Even so, the distinction between facts and values has outgrown its name: it applies not only to matters of fact vs, matters of value, but also to statements that something is, vs. statements that something ought to be. Roughly, factual statements - 'is statements' in the relevant sense - represent some state of affairs as obtaining, whereas normative statements - evaluative, and deontic ones - attribute goodness to something, or ascribe, to an agent, an obligation to act. Neither distinction is merely linguistic. Specifying a book's monetary value is making a factual statement, though it attributes a kind of value. 'That is a good book' expresses a value judgement though the term 'value' is absent (nor would 'valuable' be synonymous with 'good'). Similarly, 'we are morally obligated to fight' superficially expresses a statement, and 'By all indications it ough to rain' makes a kind of ought-claim; but the former is an ought-statement, the latter an (epistemic) is-statement.
Theoretical difficulties also beset the distinction. Some have absorbed values into facts holding that all value is instrumental, roughly, to have value is to contribute - in a factual analysable way - to something further which is (say) deemed desirable. Others have suffused facts with values, arguing that facts (and observations) are 'theory-impregnated' and contending that values are inescapable to theoretical choice. But while some philosophers doubt that fact/value distinctions can be sustained, there persists a sense of a deep difference between evaluating, and attributing an obligation and, on the other hand, saying how the world is.
Fact/value distinctions, may be defended by appeal to the notion of intrinsic value, as a thing has in itself and thus independently of its consequences. Roughly, a value statement (proper) is an ascription of intrinsic value, one to the effect that a thing is to some degree good in itself. This leaves open whether ought-statements are implicitly value statements, but even if they imply that something has intrinsic value - e.g., moral value - they can be independently characterized, say by appeal to rules that provide (justifying) reasons for action. One might also ground the fact value distinction in the attributional (or even motivational) component apparently implied by the making of valuational or deontic judgements: Thus, 'it is a good book, but that is no reason for a positive attribute towards it' and 'you ought to do it, but there is no reason to' seem inadmissible, whereas, substituting, 'an expensive book' and 'you will do it' yields permissible judgements. One might also argue that factual judgements are the kind which are in principle appraisable scientifically, and thereby anchor the distinction on the factual side. This ligne is plausible, but there is controversy over whether scientific procedures are 'value-free' in the required way.
Philosophers differ regarding the sense, if any, in which epistemology is normative (roughly, valuational). But what precisely is at stake in this controversy is no clearly than the problematic fact/value distinction itself. Must epistemologists as such make judgements of value or epistemic responsibility? If epistemology is naturalizable, then even epistemic principles simply articulate under what conditions - say, appropriate perceptual stimulations - a belief is justified, or constitutes knowledge. Its standards of justification, then would be like standards of, e.g., resilience for bridges. It is not obvious, however, that there appropriate standards can be established without independent judgements that, say, a certain kind of evidence is good enough for justified belief (or knowledge). The most plausible view may be that justification is like intrinsic goodness, though it supervenes on natural properties, it cannot be analysed wholly in factual statements.
Thus far, belief has been depicted as being all-or-nothing, however, as a resulting causality for which we have grounds for thinking it true, and, all the same, its acceptance is governed by epistemic norms, and, least of mention, it is partially subject to voluntary control and has functional affinities to belief. Still, the notion of acceptance, like that of degrees of belief, merely extends the standard picture, and does not replace it.
Traditionally, belief has been of epistemological interest in its propositional guise: 'S' believes that 'p', where 'p' is a reposition towards which an agent, 'S' exhibits an attitude of acceptance. Not all belief is of this sort. If I trust you to say, I believer you. And someone may believe in Mr. Radek, or in a free-market economy, or in God. It is sometimes supposed that all belief is 'reducible' to propositional belief, belief-that. Thus, my believing you might be thought a matter of my believing, is, perhaps, that what you say is true, and your belief in free markets or God, is a matter of your believing that free-market economies are desirable or that God exists.
Some philosophers have followed St. Thomas Aquinas (1225-74), in supposing that to believer in God is simply to believer that certain truths hold while others argue that belief-in is a distinctive attitude, on that includes essentially an element of trust. More commonly, belief-in has been taken to involve a combination of propositional belief together with some further attitude.
The moral philosopher Richard Price (1723-91) defends the claim that there are different sorts of belief-in, some, but not all reducible to beliefs-that. If you believer in God, you believer that God exists, that God is good, you believer that God is good, etc. But according to Price, your belief involves, in addition, a certain complex pro-attitude toward its object. Even so, belief-in outruns the evidence for the corresponding belief-that. Does this diminish its rationality? If belief-in presupposes believes-that, it might be thought that the evidential standards for the former must be, at least, as high as standards for the latter. And any additional pro-attitude might be thought to require a further layer of justification not required for cases of belief-that.
Belief-in may be, in general, less susceptible to alternations in the face of unfavourable evidence than belief-that. A believer who encounters evidence against God's existence may remain unshaken in his belief, in part because the evidence does not bear on his pro-attitude. So long as this ids united with his belief that God exists, and reasonably so - in a way that an ordinary propositional belief that would not.
The correlative way of elaborating on the general objection to justificatory externalism challenges the sufficiency of the various externalist conditions by citing cases where those conditions are satisfied, but where the believers in question seem intuitively not to be justified. In this context, the most widely discussed examples have to do with possible occult cognitive capacities, like clairvoyance. Considering the point in application once, again, to reliabilism, the claim is that to think that he has such a cognitive power, and, perhaps, even good reasons to the contrary, is not rational or responsible and therefore not epistemically justified in accepting the belief that result from his clairvoyance, despite the fact that the reliablist condition is satisfied.
One sort of response to this latter sorts of an objection is to 'bite the bullet' and insist that such believers are in fact justified, dismissing the seeming intuitions to the contrary as latent Internalist prejudice. A more widely adopted response attempts to impose additional conditions, usually of a roughly Internalist sort, which will rule out the offending example, while stopping far of a full internalism. But, while there is little doubt that such modified versions of externalism can handle particular cases, as well enough to avoid clear intuitive implausibility, the usually problematic cases that they cannot handle, and also whether there is and clear motivation for the additional requirements other than the general Internalist view of justification that externalist is committed to reject.
A view in this same general vein, one that might be described as a hybrid of internalism and externalism holds that epistemic justification requires that there is a justificatory factor that is cognitively accessible to the believer in question (though it need not be actually grasped), thus ruling out, e.g., a pure reliabilism. At the same time, however, though it must be objectively true that beliefs for which such a factor is available are likely to be true, in addition, the fact need not be in any way grasped or cognitively accessible to the believer. In effect, of the premises needed to argue that a particular belief is likely to be true, one must be accessible in a way that would satisfy at least weak internalism, the Internalist will respond that this hybrid view is of no help at all in meeting the objection and has no belief nor is it held in the rational, responsible way that justification intuitively seems to require, for the believer in question, lacking one crucial premise, still has no reason at all for thinking that his belief is likely to be true.
An alternative to giving an externalist account of epistemic justification, one which may be more defensible while still accommodating many of the same motivating concerns, is to give an externalist account of knowledge directly, without relying on an intermediate account of justification. Such a view will obviously have to reject the justified true belief account of knowledge, holding instead that knowledge is true belief which satisfies the chosen externalist condition, e.g., a result of a reliable process (and perhaps, further conditions as well). This makes it possible for such a view to retain Internalist account of epistemic justification, though the centrality of that concept to epistemology would obviously be seriously diminished.
Such an externalist account of knowledge can accommodate the commonsense conviction that animals, young children, and unsophisticated adults' posse's knowledge, though not the weaker conviction (if such a conviction does exist) that such individuals are epistemically justified in their beliefs. It is, at least, less vulnerable to Internalist counter-examples of the sort discussed, since the intuitions involved there pertain more clearly to justification than to knowledge. What is uncertain is what ultimate philosophical significance the resulting conception of knowledge, for which is accepted or advanced as true or real on the basis of less than conclusive evidence, as can only be assumed to have. In particular, does it have any serious bearing on traditional epistemological problems and on the deepest and most troubling versions of scepticism, which seems in fact to be primarily concerned with justification, and knowledge?`
A rather different use of the terms 'internalism' and 'externalism' have to do with the issue of how the content of beliefs and thoughts is determined: According to an Internalist view of content, the content of such intention states depends only on the non-relational, internal properties of the individual's mind or grain, and not at all on his physical and social environment: While according to an externalist view, content is significantly affected by such external factors and suggests a view that appears of both internal and external elements are standardly classified as an external view.
As with justification and knowledge, the traditional view of content has been strongly Internalist in character. The main argument for externalism derives from the philosophy y of language, more specifically from the various phenomena pertaining to natural kind terms, indexicals, etc. that motivate the views that have come to be known as 'direct reference' theories. Such phenomena seem at least to show that the belief or thought content that can be properly attributed to a person is dependant on facts about his environment, e.g., whether he is on Earth or Twin Earth, what is fact pointing at, the classificatory criterion employed by expects in his social group, etc. - not just on what is going on internally in his mind or brain.
An objection to externalist account of content is that they seem unable to do justice to our ability to know the content of our beliefs or thought 'from the inside', simply by reflection. If content is depending on external factors pertaining to the environment, then knowledge of content should depend on knowledge of these factors - which will not in general be available to the person whose belief or thought is in question.
The adoption of an externalist account of mental content would seem to support an externalist account of justification, apart from all contentful representation is a belief inaccessible to the believer, then both the justifying statuses of other beliefs in relation to that of the same representation are the status of that content, being totally rationalized by further beliefs for which it will be similarly inaccessible. Thus, contravening the Internalist requirement for justification, as an Internalist must insist that there are no justification relations of these sorts, that our internally associable content can also not be warranted or as stated or indicated without the deviated departure from a course or procedure or from a norm or standard in showing no deviation from traditionally held methods of justification exacting by anything else: But such a response appears lame unless it is coupled with an attempt to show that the externalised account of content is mistaken.
Except for alleged cases of thing s that are evident for one just by being true, it has often been thought, anything is known must satisfy certain criteria as well as being true. Except for alleged cases of self-evident truths, it is often thought that anything that is known must satisfy certain criteria or standards. These criteria are general principles that will make a proposition evident or just make accepting it warranted to some degree. Common suggestions for this role include position ‘p’, e.g., that 2 + 2 = 4, ‘p’ is evident or, if ‘p’ coheres wit h the bulk of one’s beliefs, ‘p’ is warranted. These might be criteria whereby putative self-evident truths, e.g., that one clearly and distinctly conceive s ‘p’, ‘transmit’ the status as evident they already have without criteria to other proposition s like ‘p’, or they might be criteria whereby purely non-epistemic considerations, e.g., facts about logical connections or about conception that need not be already evident or warranted, originally ‘create’ p’s epistemic status. If that in turn can be ‘transmitted’ to other propositions, e.g., by deduction or induction, there will be criteria specifying when it is.
Nonetheless, of or relating to tradition a being previously characterized or specified to convey an idea indirectly, as an idea or theory for consideration and being so extreme a design or quality and lean towards an ecocatorial suggestion that implicate an involving responsibility that include: (1) if a proposition ‘p’, e.g., that 2 + 2 = 4, is clearly and distinctly conceived, then ‘p’ is evident, or simply, (2) if we can’t conceive ‘p’ to be false, then ‘p’ is evident: Or, (3) whenever are immediately conscious o f in thought or experience, e.g,, that we seem to see red, is evident. These might be criteria whereby putative self-evident truth s, e.g., that one clearly and distinctly conceives, e.g., that one clearly and distinctly conceives ‘p’, ‘transmit’ the status as evident they already have for one without criteria to other propositions like ‘p’. Alternatively, they might be criteria whereby epistemic status, e.g., p’s being evident, is originally created by purely non-epistemic considerations, e.g., facts about how ‘p’ is conceived which are neither self-evident is already criterial evident.
The result effect, holds that traditional criteria do not seem to make evident propositions about anything beyond our own thoughts, experiences and necessary truths, to which deductive or inductive criteria ma y be applied. Moreover, arguably, inductive criteria, including criteria warranting the best explanation of data, never make things evident or warrant their acceptance enough to count as knowledge.
Contemporary epistemologists suggest that traditional criteria may need alteration in three ways. Additional evidence may subject even our most basic judgements to rational correction, though they count as evident on the basis of our criteria. Warrant may be transmitted other than through deductive and inductive relations between propositions. Transmission criteria might not simply ‘pass’ evidence on linearly from a foundation of highly evident ‘premisses’ to ‘conclusions’ that are never more evident.
A group of statements, some of which purportedly provide support for another. The statements which purportedly provide the support are the premisses while the statement purportedly support is the conclusion. Arguments are typically divided into two categories depending on the degree of support they purportedly provide. Deductive arguments purportedly provide conclusive support for their conclusions while inductively supports the purported provision that inductive arguments purportedly provided only arguments purportedly in the providing probably of support. Some, but not all, arguments succeed in providing support for their conclusions. Successful deductive arguments are valid while successful inductive arguments are valid while successful inductive arguments are strong. An argument is valid just in case if all its premisses are true its conclusion is only probably true. Deductive logic provides methods for ascertaining whether or not an argument is valid whereas, inductive logic provides methods for ascertaining the degree of support the premisses of an argument confer on its conclusion.
Finally, proof, least of mention, is a collection of considerations and reasonings that instill and sustain conviction that some proposed theorem-the theorem proved-is not only true, but could not possibly be false. A perceptual observation may instill the conviction that water is cold. But a proof that 2 + 5 = 5 must not only instill the conviction that is true that 2 + 3 = 5, but also that 2 + 3 could not be anything but 5.
No one has succeeded in replacing this largely psychological characterization of proofs by a more objective characterization. The representations of reconstructions of proofs as mechanical and semiotical derivation in formal-logical systems all but completely fail to capture ‘proofs’ as mathematicians are quite content to give them. For example, formal-logical derivations depend solely on the logical form of the considered proposition, whereas usually proofs depend in large measure on content of propositions other than their logical form.
THE ATTAINABLE GRASP TO THOUGHT
Cogito ergo sum
At the onset, its position is summed by the term of Cartesianism, the name given to the philosophical movement inaugurated by René Descartes (after’Caetesius,’ the Latin version of his name). The main features of Cartesianism are (1) the use of methodical doubt as a tool for testing beliefs and reaching certainty, (2) a metaphysical system that starts from the subject’s indubitable awareness of his own existence; (3) a theory of ‘clear and distinct ideas’ based on the innate ideas and propositions implanted in the soul by God (these include the ideas of mathematics, which Descartes takes to be the fundamental building blocks of science); (4) The theories now known as ‘dualism’-in that, there are two incompatible kinds of substance in the universe, mind (or thinking asymmetry) and matter (or extended substance). A corollary of this last theory is that human bings heterogeneously vary among composites of the unexceeded, immaterial consciousness united to a piece of purely physical machinery -the body. Another element in Cartesian dualism is the claim that the mind has perfect and transparent awareness of its own nature or essence.
The self conceived issues that Descartes presented in the first two Meditations: Aware only of its own thoughts, and capable of disembodied existence, neither in a space nor surrounded by others. This is the pure self or the ‘I’ that we are tempted to imagine as a simple unique thing that makes up our essential identity. Descartes’s view that he could keep hold of this nugget while doubting Lichtenberg and Kant criticize everything else, and most subsequent philosophers of mind.
For many people understanding their place of mind and in nature are the greatest philosophical problem. Mind is often thought to be the last domain that stubbornly resists scientific understanding, and philosophers differ over whether they fin that a cause for celebrating or scandals, Descartes gave the mind-body problem in the modern era its definitive shape, although the dualism that he espoused is far more widespread and far older, occurring in some form wherever there is a religious or philosophical tradition under which the soul may have an existence apart from the body. While most modern philosophies of mind would reject the imaginings that lead us to think that this makes sense, there is no consensus over the best way to integrate our understanding of people as bearers of physical properties on the one hand, as subjects of mental lives on the other.
The affixed nature of the philosophy of mind seeks to answer such questions as: Is mind distinct from matter? Can we define what it I to be conscious, and can we give principled reasons for deciding whether other creatures are conscious, or whether machines might be made so that thy being conscious? What is thinking, feeling, expedience, remembering? Is it useful to divide the functions of the mind up, separating memory from intelligence, rationality from sentiment, or do mental functions form an integrated whole? The dominant philosophies of mind in the current western tradition include varieties of physicalism and functionalism.
Still, the belief that philosophy of language is had informed much philosophy, especially in the 20th century, the fundamental basis of all philosophical problems, in that language is the distinctive exercise of mind, and the distinctive way in which we give shape to metaphysical beliefs. Particular topics will be made up of the division between syntax and semantics, and problems of understanding the number and nature of specifically semantic relationships, such ad meaning, reference, predication, and quantification. Pragmatics includes the theory of speech acts, while problems of rule-following and the indeterminacy of translation infects philosophies of both pragmatics and semantics.
During our intervening time, it is said of René Descartes (1596-1650) who was a French pphilosopher, scientist and mathematician. Descartes is often called the ‘father of modern philosophy,’ since he made epistemological questions the primary and central questions of the discipline. Nonetheless, this is misleading for several reasons. In the first place, Descartes’ conception of philosophy was very different from our own. The term ‘philosophy’ in the seventeenth century was far more comprehensive than it is today, and embraced the whole of what e nowadays call natural science, including cosmology, and physics, with subjects like anatomy, optics and medicine. Desecrates’ reputation as a ‘philosopher’ in his own time was based in these scientific areas. In the second place, even in those Cartesian writings that are philosophical in the modern academic sense, the epistemological concerns are different from the conceptual and linguistic inquires that characterize present-day ‘theory of knowledge.’ Descartes saw the need to base his scientific system on secure metaphysical foundations; by ‘metaphysical’ he meant inquires into ‘God and the soul and in general, all the first things to be discovered by philosophizing.’ These foundational inquiries included, to be sure. Questions about knowledge and certainty, but even here, Descartes is not primarily concerned with the criteria for knowledge claims, or with definitions of the epistemic concerns involved; his aim, is to provide a unified framework for understanding the universe. In place of the fragmented scholastic world of separate disciplines, each with its own methods and standards of precision, he aimed to construct a coherent theory of the world and man’s place within it. And this project required him ‘once in his life’ systematically to test all his former beliefs, and ti subject them to radical scrutiny, to see whether he could ‘establish’ anything at all in the science that was stable and likely to last
Briefly, Descartes’ views on knowledge were conditioned by the time in which he lived, which had witnessed a gradual erosion of beliefs held for centuries and apparently based on straightforward observation and ‘common sense.’ The most notable example of this was a long-held conviction, bolstered by the authority of the Church, hat an immovable earth was the centre of the universe. Galileo’s discovery of the moons of Jupiter (made when Descartes was a nine-year-old pupil at La Flèche) was but one piece in a mounting pile of evidence suggesting that the traditional view was radically mistaken. Descartes became obsessed by the thought that no lasting progress could be made in the sciences unless a systematic method could be devised for sifting through our preconceived opinions and establishing which of them, if mine, it was reliable. ‘Suppose we had a basket full of apples and were worried that some of them were rotten. How would be we proceed? Would we not begin by tipping the whole lot out and then pick up and put back only those we saw to be sound?’ Descartes’ ‘’Method of Doubt’ involved a determined effort to test our preconceived opinions or ‘prejudices’ to the limit, by applying a series of deliberate sceptical techniques (often derived from classical arguments for doubt that had ben revived in the sixteenth century). He points out first, that the senses (sight, hearing, touch, etc.) are often unreliable, and ‘never trusting entirely those who have deceived us is even prudent once’ (First Meditation); later, he cited such instances as the straight stick that looks bent in water, and the square tower that look round from a distance. This argument from illusion, has not, on the whole, impressed commentators; yet, there were some of Descartes’ contemporaries that pointed out that since contemporary errors become known from further sensory information, casting wholesale doubt on the evidence of the senses cannot be right. Nevertheless, Descartes, he regarded the argument from illusion as only the first stage in softening up process which would ‘lead the mind away from the senses.’ He admits that there are some cases of sense-based belief about which doubt would be insane -‘for example the belief that I am sitting here by the fire, wearing a winter dressing gown.’
At this point, Descartes introduces a fresh reason for doubt -the celebrated ‘dreaming argument. ‘How often, asleep at night, am I convinced of just such familiar events, that I am here in my dressing gown, sitting by the fire, when in fact I am laying undressed in bed observing that there are ‘no’ conclusive signs: In which being awake can be distinguished from being asleep, Descartes proceeds, in effect to mount a general doubt about whether we are justified in asserting the really extra-mental existence of any particular object that we appear to perceive via the senses. Critics of this argument have suggested that the very concept of dreaming is parasitic on the concept of waking life, so that, again, we have not been offered an overall reason for doubting the existence of external objects. Descartes’ defenders, however, can plausibly reply that if in any particular instance te possibility that one is dreaming cannot be ruled out, the solitary doubter has no guarantee of the independent existence of any given object of perception. The conclusion that Descartes eventually draws is that any paradigm of science makes existential assumptions (such as physics, astronomy and medicine) are potentially doubtful, and that only disciplines like arithmetic and geometry ‘which deal only with the simplest and most general things, despite whether they exist in nature or not enjoy intuitive certainty.’
Yet, even this last certainty is undermined in Descartes’ most radical argument for doubt -the deceiving God hypothesis: if, as I have been taught, there is an omnipotent being who created me, then ‘how do I know that he has not brought it about that I go wrong every time I add two and three or count the sides of a square?’ There may, of course, be no God, but then, Descartes reasons, I owe my existence not to a divine creator but to some chance chain of imperfect causes. Then, there is even less reason to suppose that my basic mathematical judgements are sound. By the end of the First Meditation, the mediator is ‘tumbling around’ in a vortex of doubt. There is ‘no one of my former beliefs about which a doubt may not properly be raised.’ Descartes dramatizes this horror of extreme uncertainty by invoking a ‘supreme powerful and malicious demon’ intent on deceiving me in any way he possibly can.
Despite the commonly employed label ‘Cartesian scepticism’ realizing that Descartes is in no sense a sceptic is important. The systematic doubt is merely a means to an end: The aim is to demolish to rebuild -to throw out the rubble and lose sand to reach a bedrock of certainty. That bedrock is reached in the Second Meditation in the famous Cogito argument: ‘Let the demon deceive me as much as he can, he will never bring it about that I am nothing while I think I am something. So, I must conclude that this proposition, I am, I exist is necessarily true whenever it is put forward by me or conceived in my mind,’ as Descartes phrased it in the Discourse, ‘I am thinking therefore I exist’ (je pense donc je suis) is ‘so firm and sure that the most extravagant suppositions of the sceptics were incapable of shaking it.’ The most interesting epistemic feature of the Cogito argument is the way in which Descartes extrudes certainty from the very process of doubting: The act of casting doubt on the proposition that one is thinking confirms its truth, and this in turn unavoidably implies that there must be an existing subject. Even that in existential truth, I exist, surviving everything the sceptics throw at it.
Descartes’ questioning of his previous beliefs is not as radical as is often supposed. To reach the certainty of the Cogito, he has to rely on an unquestioned underlying conceptual apparatus -for example, his grasp of what is meant by knowledge, or by doubt, and of the principal that ‘to think one must exist’ this that the Cartesian project is not, as is something suggested, ‘the validation of reason’ apart from the fleeting suggestion in the First Meditation, that even the fundamental truths of logic and mathematics might be unstable, there is never any attempt to start with a completely blank slate. If the doubt were as extreme as that, the very process of systematic meditation could never get off the ground in the first place. What Descartes aims to show, is that there is an inescapable logical limit to scepticism about what exists: Pushing such doubt to its limits shows that it is self-defeating. Once the existence of at least one item, the thinking self, has been arrived t, Descartes will attempt systematically to reconstruct a reliable body of knowledge. Yet we come up against the most striking feature of the Cartesian system from an epistemological point of view: Its radically subjective orientation. Descartes has to reconstruct the knowledge ‘from the inside outward’ -from awareness of self to knowledge of the external world. Given the wholesale doubts he has raised about the latter, he can only reinstate it by relying on the resources of his own subjective consciousness. One such resource is the idea he finds within him of a supremely perfect being, and he reasons that this can only have been placed in his mind by a really existing perfect creator -God. Once God’s existence is established by this route, Descartes can proceed to reinstate his former belief in an external world, reasoning that, since God has given him a powerful propensity to believe that many of his ideas have their source in really external objects, such objects must exist -otherwise e the deity would be systematically deceiving him, which would be incompatible with divine perfection.
Two important points need to be made about the general Cartesian approach to conative knowledge. The first is that when Descartes’ reconstruction project has been completed, the resulting edifice is very different from the ‘commonsense,’ pre-philosophical world of the man of the senses. Physical objects exist -that much is guaranteed but, ‘they may not at all exist in the way that exactly corresponds to my sensory grasp of them -for often the grasp of the senses is obscure and confused.’ To achieve a reliable grasp of the nature of physical reality. Descartes urges that we must systematically disregard the confused deliverance of the senses, and rely instead on the ‘clear and distinct’ concepts of pure mathematics that God has implanted in our souls. Even so, the resulting structure of Cartesian sciences sets out to reduce all physics to ‘what the geometers calls quantity, and take as the object of their demonstration, i.e., that to which every kind of division shape and motion is applicable.’ The world of the senses, the quantitative world of smells and tastes and colours and sounds, is thus, resolutely excluded from Cartesian science -an exclusion that remains to this day a problem for those who wish, as Descartes did, to achieve a systematic and unified understanding of reality.
The two most widely known of Descartes' schematic ideas are those of the methods of hyperbolic doubt. Each bit of an argument that, even if he may doubt, he cannot doubt that he exists. Yet we are to realize upon the fundamental components by whose functionally dynamic attributions are for Descartes' his schematic world-view that accountably his philosophical approach may objectively refuse to accept for which of depictive reason’s find in them a continuing source from which might by its concurring and evidential agreements, as we are by some understandings as formed by some sustaining primordial philosophy -all the same, he refuses to take on the obviousness for which its common sense make known to or so by understanding of indistinguishable communication. In the search for some scrupulous structural foundations in philosophically assumptive thought, which might we conclude from evidence, that is in the finding detection for which premises of doubt, again, in construing constructions by some labouriously contained fractions, are those that ease the given rejection. In that this obviousness might lay succumbing to all resolutions toward trust, and to affix the understandable value’s qualities and bring to a clearer and more of a distinctively foreseeable affirmation as to any cancellation to consider by some measure of trust. This, of course, may be construed as of Descartes’ proportionate aesthetic values, for which in their own layers of beliefs and opinions overshadow that which is thoroughly given toward his view of truth. Composite characteristics are exceedingly hesitant, that the simple fact of doubting it, and the inescapable inference that something exists doubting, namely Descartes himself.
His next task is to reconstruct our knowledge piece by piece, such that at no stage is the possibility of doubt allowed to creep back in. In this manner, Descartes proves that he himself must have the basic characteristic of thinking, and that this thinking thing (mind) is quite distinct from his body, that the existence of God, which of the existence and the nature of the external world, and so on. What is important of this, as, of course, that for Descartes is, first, that he has shown that knowledge is genuinely possible (and thus that sceptics must be mistaken), and, second, that, more particularly, a mathematically-based scientific knowledge of approving to the material world of its studious possibilities.
A self-knowledge and self-identity are normally the way one knows something about oneself is significantly different from the way one knows the same sort of thing about anyone else. Knowledge of one’s own current mental states is ordinarily not grounded on information about behaviour and physical circumstances. Knowledge of one’s actions, and of such facts as that one is sitting or standing, is usually ‘without observation’ o r, at any rate, not based on the sorts of observations that ground one’s knowledge of the actions and posture of others. One’s perceptual knowledge of one’s situation in the world, e.g., that one is facing a tree, differs markedly from the perceptual knowledge others have of the same facts, since it usually does not involve perceiving itself. One’s memory knowledge of one’s own past is normally very different from one’s memory knowledge of the pasts of others; one remembers one’s thoughts, feelings, perceptions and actions ‘from the inside,’ in a way that does not depend on the use of any criterion of personal identity to identity a remembered self as oneself.
Although in all these cases’ one could speak of a ‘special’ first-person access, it is the excess people have to their own mental state’s hat has attracted the most attention. Some philosophers have denied that there is a fundamental difference between first-person and third-person knowledge of mental states. Others, have maintained that where the difference seems most pronounced, i.e., for pain ascriptions, the first-person’avowals’ are not really expressions of knowledge at all. So that, of the philosophy of mind, is founded on the rejection of the Cartesian idea that a person discloses the contents of his mind by identifying inner objects and describing them, hence of an intension is not based on a self-examination that parallels the investigation of the world around us, it is only marginally liable to error and is an artificial expression of the intention replacing a natural one.
Such views are manifestations of the twentieth-century reaction against Cartesian views about self-knowledge that are often associated with the claim that their ae radical first-person/third-person asymmetries. These include the views that the mind is transparent to itself, which mental states are ‘self-intimating,’ those first-person ascriptions of mental states are infallible, and that self-knowledge of mental states serves as the foundation for the rest of our empirical knowledge, least of mention, tat the view is sometimes stated about the structure of knowledge than of its justified belief. If knowledge is true justified belief, and some further condition, one may think of knowledge as exhibiting a foundationalist structure by virtue of the justified belief it involves. Such views have been undermined by the work of Freud, with its postulation of a realm of unconscious whishes, intentions, etc., by work in cognitive psychology that shows most of the ‘information processing’ in the mind to be unconscious which shows many sorts of introspective reports to be unreliable, and by philosophical criticisms of foundationalist account of knowledge. All the same, most recent theorists who reject these Cartesian claims would agree that the reasons for their rejection are not reasons for denying that there is first-person knowledge of mental states that differs importantly from third-person knowledge of the same phenomena.
One question about such knowledge is whether it is appropriately thought of as observational, i.e., as grounded in as kind of perception that could be called ‘inner sense.’ Modern defenders of the view that such knowledge is observational, e.g., D.M. Armstrong, 1968, that perceiving something to be a matter of a bing so related to it that it’s having certain properties is apt to cause the non-inferential belief, that there is something that has them. On this conception, saying it seems plausible, that one perceives mental states and events occurring in one’s own mind, in virtue of an internal mechanism by which mental states cause true beliefs about themselves, but cannot perceive those occurring in the minds of others, and that it is in this that one’s ‘special access’ to one’s mind consists.
Some who agree with such a ‘reliable internal mechanism’ view of introspective awareness would object to describing such knowledge as perceptual. In paradigm cases of perception, e.g., vision, the causal connection between the object perceived and the perceiver’s belief bout it is mediated by a state of the perceiver, a ‘sense-experience,’ which in some sense represents the object, that the subject can be aware of (in being aware of the look or feel of a thing). There may be no such intermediaries between our sensations, thoughts, beliefs, etc. and our beliefs about them, and this seem a reason for denying that our awareness of them is perceptual.
A different objection questions the idea, implicit in the perceptual model, that there is only a contingent connection between having mental states and being aware of them, just as there is only a contingent connection between there being trees and mountains and thee being perceptual awareness of them. It makes doubtful sense to suppose that there are creatures that have pain without having any capacity whatever to be aware of their pains. A consideration of the explanatory role of self-knowledge suggests that for many kinds of mental states the very capacity to have and conceive of such states involves immediate ‘first-person access’ to the existence of these states in oneself. To mention just one instance, if being a subject of beliefs and desires involves being at least minimally rational, and if rational revision of one’s belief-desire system in the light of new experiences requires some knowledge of what one’s current beliefs and desires are, then being a subject of such states requires the capacity to be aware of them. While we should reject any self-intimation thesis strong enough to rule out the possibility of a self-deception, or to deny mental states to animals and infants, it is far from obvious that the nature of mental states is distinct from their introspective accessibility in the way the observational model implies
Lichtenberg denied that Descartes had a right to say, ‘I think,’ Claiming that he was only entitled to ‘It thinks.’ Hume (1739) famously denied that when one introspects one find any item, beyond one’s individual perceptions, that could be the self or subject that ‘has’ them. Such denials have led some (including Hume) to deny that there is any such self or subject, and have led others to wonder how we can have knowledge of such a thing or refer to it with ‘I.’ Arguably, such denials lose their force if we abandon the observational model of self-knowledge; what is disturbing is the idea we do perceive ‘b y inner sense’ perceptions, thoughts, etc., but do not perceive anything that could be their subject. Of course, if perceiving something is construed merely for being so related to it as to acquire, in a reliable way, true beliefs about it, our capacity for self-knowledge involves our being able to perceive both individual mental events or stares and the self individuals who have them.
The peculiarities of self-knowledge are, nevertheless, closely tied to the peculiarities of a self-reference. If the amnesiac Joe Jones discovers that Joe Jones is the culprit, without realizing that he himself is Joe Jones, this will not be case of self-knowledge in the sense that concerns us, eve n though it is a case in which the person known about is the Knower himself. We are concerned with cases in which someone knows that he himself, or she herself, is so and so, where this is knowledge the Knowers would express by saying ‘I am so and so.’ One feature of first-person reference is that it in no way depends on the availability of individuating descriptions: One can refer to oneself with ‘me’ without knowing of any description that could be used to fix its reference. A related feature of ‘me’ is precisely where ‘I . . .
Judgements are known in distinctively first-personal as that they have this immunity to error through misidentification. ‘I’-judgements that do not have this immunity, e.g., ‘I am bleeding,’ if implied from the blood on the floor, always have among their grounds some that do, e.g., ‘I see blood’ OR ‘There is blood near me.’ It is arguable that part of what gives first-person content to beliefs and other mental states are their relations to distinctively first-person ways of knowing, and that without such ‘special access’ there could be no first-person reference t all. Still, another important feature of ‘me’-. . . . Judgements are their intimate relation to action, the amnesiac Joe Jones will not be moved to action b learning that Joe Jones is I danger, but will be if he learns in addition that he is Joe Jones and so he himself is in danger.
A stronger and more controversial claim are that the special excess persons have to themselves enters the very identity conditions for the sort of things the persons are. Many have argued, following Locke, that memory access is pat of what determines the temporal boundaries of persons. A major determinant o the spatial boundaries of persons, i.e., o what counts as part of a person’s body, is the extent of direct voluntary control, and this is intimately tied to the special epistemic excess persons have to their own voluntary actions. A familiar Kantian idea is that unit of consciousness. Different states belonging to the same subject-in some way involve consciousness, or the possibility of consciousness, of this unity.
For the question of why there is something and not nothing, everything real and nothing unreal belongs to the domain of Being. Nevertheless, there is little useful that can be said about everything that is real, especially from within the philosopher’s study, so there can apparently be such a subject as Bering by itself. Nevertheless, the concept has a central place in philosophy from Parmenides to Heidegger. The central question of ‘why is there something and not nothing?’ prompts logical reflection on what it is for a universal to have an instance, and a long history of attempts to explain contingent existence by reference to a necessary ground. In the tradition since Plato, this ground becomes a self-sufficient, perfect, unchanging, and eternal something identified along some God or God, but whose relation with the every-day world remains unknown. By defining God as ‘something than which nothing greater can be conceived,’ God then exists in the understanding, since we understand this concept. However, if, . . . He only existed in the understanding, something greater could be conceived, for a being that exists in reality is greater than one that exists only in the understanding. However, we can conceive of something greater than that which nothing greater can be conceived, which is contradictory. Therefore, God cannot exist only in the understanding, but exists in reality. For if the answer to the question of why anything exists is that some other thing of a similar kind exists, the question merely arises again. So, the God that ends the question must exist necessarily, it must not be an entity of which the expressions as a quantity are the kinds of questions obtainably in their raise of a relief.
Modern logic gives little comfort to these speculations, and prompts suspicion that the question of why there is something ad not nothing is either ill-formed or profitless, since any intelligible answer will merely invite the same question. A central mistake in the area is to treat Being as a noun that identifies a particularly deep subject-matter. This is parallel to treating nothing as a name of a particular thing, perhaps is an object of dread or fear. The modern logical treatment of these notions by means of quantifiers and variables provides a defence against this error and others. The less abstract par of the study of being concerns the kinds of things whose existence e we have to acknowledge: Abstract entities, possibilities, numbers, and so on, and disputes over their reality from the subject of ontology.
The modern treatment of existence in the theory of ‘quantification’ is sometimes put by saying that existence is not a predicate. The idea is that he existential qualifiers are themselves an operator on a predicate, indicating that the property it expresses has instances. Existence is therefore treated as a second-order property, or property of properties. In this it is like number, for when we say that there are three things of a kind, we do not describe the things (as we would if we said there are red things of the kind), but instead attribute a property to the kind itself. The parallel with numbers is exploited by Frége in the dictum that affirmation of existence is merely denial of the number nought. A problem for the account is created by sentences like ‘This exists,’ where some particular thing is indicated. Such a sentence seems to express a contingent truth (for this might not have existed), yet no other predicate is involved. ‘This exists’ is therefore unlike ‘Tame tigers exist,’ where a property is said to have an instance, for the word ‘this’ does not locate a property, but only an individual. Possible worlds seem able to differ from each other purely in the presence or absence of individuals, and not merely in the distribution of exemplifications of properties.
Descartes proves the existence of the world, not from the testimony of our experience of this fact but from the innate idea of the ‘res extensa.’ We have a certain idea that is clear (presenting but one quality, extension), and it is distinct from the ‘res’ cogitans.’ This idea, granted the facility of God, and privy to any falseness, therefore the world exists, and its contributive principal claims to the attribute of extension or the annex of supplementary progression.
Concerning the nature of this corporeal world, Descartes distinguishes between what is presented for us through our senses (colours, odours, tastes, tactile sensations). That in which comes by means of the world is a machine, an inorganic world of plants and animals, and even mans, i.e., a dimension, figures, weight, position, motion. The first, not guaranteed by the veracity of God, do not have objective value; they are secondary qualities, modes with which the subject represents reality. The second that, according to Descartes, must originate through innate values, that are primary qualities and are guaranteed by the veracity of God, therefore they are real and objective.
The essential attribute of extension characterizes the Cartesian World (‘res’ extensa’), which is infinite. In this extension the power of God has placed force and movement, which the principal of absolute causality has determined. Not purpose (finalism), but mechanical determination (the laws governing ‘matter’ and ‘mathematical motion’), the determining succession of phenomena in the physical world of theory, is claimed by virtue in the ‘res extensa.’ By which, the world is a machine, an inorganic world of plants and animals, and even mans, our uniformity through which even bodies at rest or otherwise, are comfortably considered as they are machines governed by laws established by the continuity of their causal motions. As for us, the accessible groundwork may that to see, in what is otherwise the discontinuity that is so justified through the acquiring associations by some non-uniform motion and in opposition too such, is the continuity of justifications, under which motion may freely bring us the secret reservoir of continuatives phenomenons, that to its topic, is alike, maintained by some functional reason of truth, so in that respect has the quality of being to restrictive harmonious causalities, for which it may not have what is freely given peripherally by its most favourable differentiation.
The entire Cartesian system rests upon metaphysical dualism: ‘res cogitans’ (God and the human soul) and ‘res’ extensa’ (the corporeal world). These peculiar and yet particular realities are considerately as to think, that, in as far as liberty and activity are essential to a world-view of thought, the thinking being. The succession by which mechanical determinism and passivity are predominately of what is best for all possible worlds, especially of those that establishes them of the ‘res’ extensa.’ Metaphorical duality in both the soul and corporeal worlds are essentially a bipolar product of existent value qualities that have excluded all reciprocal action between the two substances because it is impossible. Thus there is opened the problem that rationalism later took up: the determination of the relationship between spirit and matter; between God (the infinite spirit) and the world (finite matter).
This problem presented even graver difficulties about the Cartesian idea of substance -that which exists without need of want concurs by its arranging evidence that may by chance of any other to exist. Such a definition of substance is applicable only to God, who because, he is ‘Causses’ is a substance that does not need of wanting to concur of another to exist. However, finite beings also are substances and although Descartes had added that finite beings need to align with want if there is to be of any concurring intent of the God that exists, the passage to the monistic idea of single substance appears quite open; this was to be the point of departure for Spinoza.
To this we must add the fact that Descartes considers thought not as a desire toward actions upon, but as the thinking substance (‘res cogitans’), that is, as a soul, whose essence is thought. Indirectly, this formality of uniting designated by its consistency that only when to God, had consequentially amounted by some detectable teachings of Descartes, and especially the danger of unifying the ideas between man and God is made easier, so that the inactive latency through which its danger is unquestionably its source to pantheism.
In the world of Cartesian matter, there exist no qualities, but only quantity, matter and motion, which act fatally, necessarily and mechanically. The mechanistic concept was to be inherited by Rationalism and Empiricism, which considered the world as a huge machine acting through mechanical forces, without purposes.
Cartesian Rationalism finds its application even in ethics. For Descartes, ethics is the science of the end of man, and this end must be determined by reason. Before one can accredit reasons for arriving at the knowledge of such an end, and by means of attributed sanction would mean in having been by reaching it. The philosopher and only he can have by reassuring those troubled of peace of mind, least of mention, the paradigm from which he will comply with until determining the rational morality that appears through reason alone. Provisory morality is made up of a few precepts: Live according to the politico-religious opinions and customs of the country, inference of mind moderates, and not exemplified by extreme opinions; govern yourself with constancy, without leaving undisturbed or, placed of yourself in having the quality of being distracted by opportunistic considerations. In a word, live in a way that assures you the greatest tranquillity.
Regarding definitive morality, Descartes holds to the full liberty of God, so that all depends on the divine liberty. God, if he so wished, could have created a world governed by moral principle opposed to those which hold today. Such an idea brings ethics to the brink of disaster. For which is interchangeably accorded by the similarity that in returning to its absolute majority, the principals, from which we can trace from such is to realize of the outstanding behaviour as familiarized in those of the same features as characterologically emphasized through their justification. In the absolute essence of God the interconnective activities are once, again, very well grounded in the subjective act of his will.
Granted the present order of creation, Descartes recognizes that the end of man is virtue and happiness. The actuation of this end is caused through reason -through the knowledge of God, of the soul, and of the world. It is attained through knowledge of God because God is the creator and unifier of the universe; of the soul, because the soul makes clear to us our superiority over material nature; of the physical world, because, governed by causal necessity, it teaches man the virtue of resignation and indifference in the face of the evils of life. As are evident, Cartesian morality does not greatly differ from Stoic ethics in which the wise man appeals to reason to assure himself of tranquillity and felicity.
The first possible solution lay in uniting Cartesianism with Platonism and conceiving of the two Cartesian substances (thought-substance and extended substance) as attributes deriving from a single divine substance. This was the solution of Spinoza, the strongest and most coherent of the Cartesian thinkers. He abolished the distinction between finite and infinite, and explained monistically and pantheistically the procession of the finite from the infinite. Spinoza answered the first of the unsolved questions, that of the relationship between God and creatures. Still, he maintained the second distinction and determined the relationship between soul and body by a psycho-physical law: That which is produced in thought by means of it’s very nature that from its particular premise of axiomatic determination, for which it can be properly detected in the accession of (body).
The second possible solution came from Augustinians. Augustinians, faced with the impossibility of deriving ideas from experience, had recourse to God, to a divine illumination in which God implants ideas in the human intellect. This supernatural intervention or influence could be extended to all finite reality in a way that fills the gap between the infinite and the finite, between spirit and matter, through the intervention of God Himself. This was the solution taken by Malebranche, according to whose creatures are the simply occasioned; a directorial intervention of God is the direct cause of all effects.
As Christian Malebranche maintains the distinction between God and the world, two forces, which were unified in Spinoza. Yet in determining the relationship between God and the world, Malebranche also has recourse to God. This was to achieve within the assemblage that the latent immanentism in Cartesian Rationalism was not revealed in the concept of substance in that their relationship between the two substances.
The third possible solution was sought in bringing Cartesian Rationalism into harmony with Aristotelian Scholasticism. As bearing for its consequent reason, wherefore to endeavouring a yield that is succumbing to fill the gap, in that which it can only subsist between what could we prove as a discerning relationship is respected between spirit and matter, least of mention, we are properly equipped within us to endorse of all sustaining properties that reserve the containing of rights toward that which is moderately the proper idea of potency, and so, that, as to flow spontaneously in accord within those pre-established propositional intuitivism are sanctioned by God. This law would also explain the relationship between the finite and the infinite. The monad of Leibniz is developed according to a pre-established harmony; its development is a passage or transition from a potential state to a state of representation.
Despite these intrinsic deficiencies and despite the opposition that Cartesianism has caused, that from its foremost appearances are both in the field of philosophy (Gassendi, Hobbes). Moreover, that of religions (both Catholic and Protestant), are we to be suspended from our participation through which Cartesianism, as in following the rapid circulatory presentations as displaced throughout European representations of ascendancy, and if, by way through which thought has succumbed of the period. It influenced all branches of culture. Catholic thinkers for example, those at noted centres like the Paris Oratory and the Benedictine abbey of Port-Royal, favoured the supereminent position it gave to God and the soul. The Jansenist polemics that Cartesianism instigated are a proof of this; scientists liked the geometric spirit of the system; philosophers and litterateurs were pleased with the clear and distinct ideas and the spirit of criticism carried out according to rational methods. The classic land of Cartesianism, naturally, is France during its golden age of literature.
Empiricism also developed along with Cartesian Rationalism, and felt its influence. Intuitive Empiricism is opposed to Rationalism as sensitive and intellective knowledge is in opposition. Nevertheless, it felt the influence of Cartesianism, first in a negative sense, in as far as Empiricism now rose to reaffirm its premises in its debates with Rationalism (Hobbes, Locke), in a positive way it was also influenced in as far as the principle of immanence in common to both Empiricism and Rationalism. In that Cartesianism, directly or indirectly, is that predominating tendency in the philosophy of this period; it prepares the way for Illusionism, and through Illusionism it reaches Immanuel Kant.
Descartes, in his work ‘Discourse on Method,’ has been given to the criticism of the education under which he had received (a criticism that is indirectly an attack on the Scholasticism of his day). He goes on to set up the new method, but, yet, according to him, it must be based within the characterized potential given to assure of some essential formalities as to prove, by its significance to follow all scientific and philosophical research. These laws are four: (1) To accept nothing as true that is not recognized by the reason as clear and distinct; (2) To analyse complex ideas by breaking them down into their simple constitutive elements, which reason can be intuitively apprehended; (3) Their resultant amount is to be reconstruction for within the beginning come the sublime simplicity of ideas and working synthetically toward the complex; (4) Show some accountable adequacy in a complete figure in work, the data to the problem, expending of steps in both methods of induction and deduction.
Better to understand these laws, we must note that for Descartes the point of departure is the ideas, clearly and distinctly known by the intellect
-the subjective impressions on the intellect. Beyond these clear and distinct ideas one cannot go, and why the ultimate principle of truth consists in the clearness of the idea. Clear and distinct intuitions of the intellect are true. For Descartes, such clear and distinct intuitions are thought representations held by themselves as they stand alone for the I-ness that they represent (‘Cogito’) and the theory of some enlarged and developing expansion.
Having arrived at this starting point (uncluttered and distinctive ideas), the intellect begins its discursive and deductive operation (represented by the second and third rules). The second law (called analysis) directs the elementary notions reunited with the clear and distinct ideas (the minor of the Scholastic syllogism). The third law (synthesis) presents them in every bit as the conclusion flows from the preface. The final law (complete enumeration) stresses that no link in the deductive chain should be omitted and that every step should be logically deduced from the starting point of distinctively clear and distinct ideas. Labouriously, our gaiting endeavours of motion, can only prove proper when issues are established from an ancestral bipedalistic locomotion, as well, we can only travel one step to the next. Nonetheless, we will have obtainably gained representation through our own achieve, that of a set function of coordinate systems is regulated by their truths from which all will clearly be justly as distinct from one another. Because all those that is categorized as in participants might there be of them the same degree of truth enjoyed, least of mention, as of us that forfeit the directorial direction through it’s most originally formidable of ideas, and, from only which it can be explicitly clearer and distinctively purposive.
This, as we know, is the method adopted in mathematics. Descartes transferred it to philosophy to find clear and distinct concrete ideas, and of deducing from these, through reason alone, an entire system of truths that would also be real or objective. The Aristotelia-Scholastic method (and that, given to an overall inclination to classical realism) is also deductive, but it is very different from that of Descartes. Scholastic deduction is connected with objective reality because ideas are abstractions of the forms of the objects that experience presents. Thus, both the concreteness of the ideas and the concreteness of the deductions based on these ideas is justified.
In Descartes ideas do not come from experience, but the intellect finds them within itself. Descartes declares that only these ideas are valid in the field of reality. Thus the concreteness (or the objective validity) of an idea is dependent upon its own clearness and distinction.
Descartes, because of the principle already established in his method, had first to seek out a solid starting point (a clear and distinct concrete idea), and from this opens his deductive process. To arrive at this solid starting point, he begins with methodical doubt, that is, a doubt that will be the means of arriving at certitude. This differs from the systematic doubt of the Skeptics, who doubt to remain in doubt. Made accessibly available, as far as having made possible to see the doubt of all the impressions that exist within my knowing faculties, whether they are those impressions that come to me through the senses or through the intellect. I may doubt even mathematical truths, in as far as it could be that the human intelligence is under the influence of a malignant genius which takes sport in making what is objectively irrational appear to me as rational.
Doubt is thus carried to its extreme form. Nonetheless, asides this fact, doubt causes to rise in me the most luminous and indisputable certainty. Even presupposing that the entire content of my thought is false, the incontestable truth is that I think: One cannot lack confidence in doubt without thinking, and if I think, I exist: ‘Cogito ergo sum.’
It is to be observed that for Descartes the validity of ‘Cogito ergo sum’ rests in this, that the doubt presents intuitively to the mind the subject who doubts, that is, the thinking substance. In this, Cartesian doubt differs from that of St. Augustine (‘Si fallor, sum’), which embodies a truth sufficiently strong to overcome the position of Skepticism. Gainfully to employ the ‘Cogito ergo sum,’ Descartes is to presume, not only stifling or to subdue the Skeptic position, but as the supportive foundation for which its structural data format of a primary reality, the existence of the ‘res cogitans,’ is of the essence, in ways too further research, for which it has betaken.
This is the point that distinguishes the classic realistic philosophy from Cartesian and modern philosophy. With Descartes, philosophy ceases to be the science of being, and becomes the science of thought (epistemology). Whereas, at the outset, being applied to as conditioned to thought, now it is thought that conditions being. This principal, mostly realized by the philosophers immediately following Descartes, was to reach its full consciousness in Kant and modern Idealism.
The ‘Cogito’ reveals the existence of the subject, limited and imperfect because liable to doubt. Arriving at an objective and perfect reality is necessary, i.e., to prove the existence of God. Descartes uses three arguments that can be summarized thus: (1) Cogito has given me a consciousness of my own limited and imperfect being. This proves that I have not given existence to myself, for in such a case I would have given myself a perfect nature and not the one I have, which is subject to doubt. (2) I have the idea of the perfect: If I did not possess it, I could never know that I am imperfect. Within all possibilities, from where comes the emergent idea of the perfect? Not from myself, for I am imperfect, and the perfect cannot arise from the imperfect. Therefore it comes from a Perfect Being, that is, from God. (3) The very analysis of the idea of the perfect includes the existence of the perfect being, for just as the valley is included in the idea of a mountain, so also existence is included in the idea of the perfect.
Regarding the nature of God, Descartes chose for less of the same attributes as does traditional Christian theistic thought. In Descartes, however, these attributes assume a different significance and value. God, above all, is absolute substance: The only substance, properly so-called (so the way is open to the pantheism of Spinoza). An attribute that has great value for Descartes is the veracity of God.
God: the perfect being, cannot be deceived and is unable to deceive. Thus, the singularity of God serves as a guarantee for the entire series of collection as acclaimed by an intuitive certainty and its distinctiveness inhabited of such characteristic cleanliness in order, that is readily seen through the perfection of ideas. They are true because if they are not true, I, having proved the existence of God, would have to say that he is deceiving, and perhaps, less than creating a rational creature from which one who is, can be deceived even in the apprehension of clear and distinct ideas. Thus, with the proof of the existence of God, the hypothesis of a malignant genius falls of its own weight.
Regarding the origin of ideas, Descartes holds that the idea of God, all primitive notions, all logical, mathematical, moral principals, and so forth, are innate. God is the guarantee of the truth of these innate ideas. Alongside these innate ideas Descartes distinguishes two other groups of ideas (a) the adventitious, which are derived from the senses; (b) the fictitious, which are fashioned by the thinking subject out of the former. Both groups are considered of little worth by Descartes because they do not enjoy the guarantee of the divine veracity, and so are fonts of error. Only innate ideas and the rational deduction prospered from them have the value of truth. This proves the existence of the world, not from the testimony of our experience of this fact but from the innate idea of the ‘res extensa.’ We have a certain idea that is clear (presenting but one quality, extension), and it is distinct from the ‘res’ cogitans.’ This idea, granted the veracity of God, cannot be false; Therefore the world exists, and its principal attribute is extension.
Concerning the nature of this corporeal world, Descartes distinguishes between what is presented through the senses (colours, odours, tastes, tactile sensations) and that which comes by way of the intellect, i.e., dimensions, figures, weight, position, motion. The first, not guaranteed by the veracity of God, do not have objective value; they are secondary qualities, modes with which the subject represents reality. The second that, according to Descartes, must be innate ideas, are primary qualities and are guaranteed by the veracity of God; therefore, they are real and objective.
To this we must add the fact that Descartes considers ‘thought’ not as an executed function but as the thinking substance (‘res cogitans’), that is, as a soul, whose essence is thought. Forthwith, this is the identification that could only belong to God. Therefore, seeing it in this teaching of Descartes throughout the dangers of unifying the conceptual representations of man and God is easy (‘Homo Deus’) and consequently the latent danger of pantheism.
In the world of Cartesian matter, there exist no qualities, but only quantity, matter and motion, which act fatally, necessarily and mechanically. The mechanistic concept was to be inherited by Rationalism and Empiricism, which considered the world as a huge machine acting through mechanical forces, without purposes.
Regarding definitive morality, Descartes holds to the full liberty of God, so that all depends on the divine liberty. God, if he so wished, could have created a world governed by moral principals opposed to those with which we hold today. Such ideas bring ethical disaster, in that, if morality is like this would it not be found through its justification in the absolute essence of God or in the arbitrary act of his will.
Granted the present order of creation, Descartes recognizes that the end of man is virtue and happiness. The actuation of this end is caused through reason -through the knowledge of God, of the soul, and of the world. It is attained through knowledge of God because God is the creator and unifier of the universe; of the soul, because the soul makes clear to us our superiority over material nature; of the physical world, because, governed by causal necessity, it teaches man the virtue of resignation and indifference in the face of the evils of life. As evident, Cartesian morality does not greatly differ from Stoic ethics, in which the wise man appeals to reason to assure himself of tranquillity and felicity. Descartes left two questions unsolved: (i) the determination of the relationship between the infinite substance (God) and finite substance (the world), and (ii) the relationship between the spirit-substance (the soul) and the extended substance (body).
To fill the gap that he left between the infinite and finite, between spirit and matter, as it was, only three possible solutions are to be, that only once are we to have had to enjoy of something through the recourse to an earlier shape or type that in all forms that enlighten us to some philosophical deprivation. All three solutions were tried and developed by later philosophers: Spinoza, Malebranche and Leibniz, whose systems can justly be considered as developments of the rationalistic premises of Cartesian principals.
The first possible solution lay in uniting Cartesianism with Platonism and conceiving of the two Cartesian substances (thought-substance and extended substance) as attributes deriving from a single divine substance. This was the solution of Spinoza, the strongest and most coherent of the Cartesian thinkers. He abolished the distinction between finite and infinite, and explained monistically and pantheistically the procession of the finite from the infinite. Spinoza answered the first of the unsolved questions, that of the relationship between God and creatures. Nonetheless, he maintained the second distinction and determined the relationship between soul and body by a psycho-physical law: That which is produced in thought by it’s very nature finds’ determination in extension (body).
The second possible solution came from Augustinians. Augustinians, faced with the impossibility of deriving ideas from experience, had recourse to God, to a divine illumination in which God’s very implantation to not any but of more ideas that implicate man as having to enact in the light of a unique and comprehensible intellect. This supernatural intervention or influence could be extended to all finite reality in a way that filled the gap between the infinite and the finite, between spirit and matter, through the intervention of God Himself. This was the solution taken by Malebranche, according to whom creatures are the simple occasions; a direct intervention of God is the direct cause of all effects -Occasionalism.
As Christian Malebranche maintains the distinction between God and the world, two forces, which were unified in Spinoza. However, in determining the relationship between God and the world, Malebranche also has recourse to repose of God. By this he obtainably achieves the originality that is found, through the means of the latent constructs that seem most effectively striking for the Cartesian Rationalists. That, not to acknowledge the conceptual substances, is not to exceed in the differentiations between any two substances, from which will be found to have all of the same. The third possible solution was sought in bringing Cartesian Rationalism into some related harmonic symmetry with Aristotelian Scholasticism. Yet, to endeavour through the persuasions, least of mention, those that have possession for bringing us to a certain state of particular satisfactions, in that of some fixed relationship between spirit and matter can by way of accommodating any of the ideas from which are construed by their conceptual determinants. Their circulatory spontaneity is comparatively distributively contributive, as they over flow within the dynamics of emptiness, by that, their participating functions are accorded by laws that pre-established the penetrations curtailed through discovery, also, it might be to some effect, that their appraisals are very much as been sanctioned from God. This law would also explain the relationship between the finite and the infinite. The monad of Leibniz is developed according to a pre-established harmony; its development is a passage or transition from a potential state to a state of representation.
In the face of these intrinsic deficiencies and in spite of appositional constraints with which Cartesianism has caused, in a major way there is given to appear of both subject fields of philosophy (Gassendi, Hobbes), and the religiosity of combining formidable denominations (both Catholic and Protestant), bringing together the estranged dissimilarities by foreign legitimacies that are thoroughly categorized by enforcing priorities of culminating Cartesianism, but, it is nonetheless, that a spread of rapid emigration throughout Europe and representations in the dominant vectors of thought, so let us be pleased of the ripening season. It influenced all branches of culture. Catholic thinkers for example, those at noted centres like the Paris Oratory and the Benedictine abbey of Port-Royal, favoured the supereminent position it gave to God and the soul. The Jansenist polemics that Cartesianism instigated are a proof of this; Scientists liked the geometric spirit of the system; philosophers and litterateurs were pleased with the clear and distinct ideas and the spirit of criticism carried out according to rational methods. The classic land of Cartesianism, naturally, is France during its golden age of literature, the age of Louis XIV.
Descartes proves the existence of the world, not from the testimony of our experience of this fact but from the innate idea of the ‘res extensa.’ We have a certain idea that is clear (presenting but one quality, extension), and it is distinct from the ‘res’ cogitans.’ This idea, granted the veracity of God, cannot be false; therefore the world exists, and its principal attribute is extension.
Concerning the nature of this corporeal world, Descartes distinguishes between what is presented through our senses (colours, odours, tastes, tactile sensations) and that which comes by way of the intellect, i.e., dimensions, figures, weight, position, motion. The first, not guaranteed by the veracity of God, do not have objective value; they are secondary qualities, modes with which the subject represents reality. The second that, according to Descartes, must be innate ideas, are primary qualities and are guaranteed by the veracity of God; so they are real and objective.
The Cartesian World is characterized by the essential attribute of extension (‘res extensa’), which is infinite. In this extension the power of God has placed force and movement, which are determined by the principal of absolute causality. Not purpose (finalism), but mechanical determination (the laws governing matter and mathematical motion) governs the succession of phenomena in the physical world, in the ‘res extensa.’ The world is a machine. The inorganic world, plants and animals, and even man, to his body, are machines governed in the laws existent through the causality of motion.
The integrated priority bestowed of the Cartesian system rests upon its metaphysical dualism: ‘res cogitans’ (God and the human soul) and ‘res’ extensa’ (the corporeal world). These two realities are irreducible, in so far as thought, liberty and activity are essential to the world of the thinking being, and extension, mechanical determinism and passivity are essential to the world of the ‘res extensa.’ All reciprocal action between the two substances is excluded because it is impossible. Thus there is opened up the problem that was later to be taken up by rationalism: the determination of the relationship between spirit and matter; between God (the infinite spirit) and the world (finite matter).
Rationalism, however, is a philosophical system based on methods of inquiry grounded in reason, primarily that of mathematical deductive reasoning. Discounting sensory experience as the source of knowledge, extreme rationalists believe that all complex systems of information, such as the truths of the physical sciences and history can be derived simply by thinking about the subjects as consequences of axiomatic principle and their logical corollaries.
Rene Descartes is one best-known proponent of rationalism. He sought to outline a process of philosophical thought that was independent of the old scholastic and theological traditions of his time. Believing that all sound judgments must go on from a mathematical basis, he created of what is called ‘The Cartesian Method.’ Its four basic laws are as follows: The Cartesian Methods comprise as of: (1) Committing to nothing, would define of anyone as not to accept any propositions as true, that are not clear and distinct. (2) Break a problem down into its constituent parts and analyse it as such. (3) Structure thoughts from simple too complex as the order of study. (4) Enumerations must be complete with nothing omitted.
This systematic approach is a way that mathematics is structurally given. As, Descartes applied it to philosophy with which its intention was that it might make metaphysically inquire into the supplementary formality as distinguished through the methodological clearnesses justly as of making of analogous examples much as they can be made clearly by meaning. Making into of what might be agreeable, is that of the satisfactory behaviour -fixed and as a user of this method that is mostly famous to the Cartesian statement: ‘Cogito ergo sum‘ (I think; therefore I exist), where he formed the basis for his metaphysics. He thought that doubt was simply a different form of thought, so ‘doubting’ that one did exist was not a serious threat to validity of that principal. It was the intuitively known axiom that formed the basis for the rest of Descartes' philosophy of Rationalism.
Descartes' next work was with the concept of God, a perfect being in his belief that he sought to prove in existence of, . . . He constructed his proof in the following manner, following his own Rationalist method to do so: The Cartesian Proof of God: (A) I am subject to doubt; therefore I am ‘the perfect’ to grasp onto the imperfect; thus, I am not the cause of my existence. (B) I have the ‘idea‘ of ‘the perfect.’ This idea must come from a perfect Being. That to a greater extent and made clearly satisfactorily, when its point is implied directorially furnished by the analysis of the idea does the existence of the perfect being.
As for ideas, Descartes holds that some ideas come from God; these ideas are innate. Others are derived from sensory experience, and still others are fictitious, that is; they are created by the imagination. He thinks that the only ideas from which are, in fact, valid in those that are innate. All others are subject to fallacy. Also, central to Descartes' argument was his notion of the dualism of substances. Cartesian thought has remained central to philosophy, especially during the 17th century of almost 300 years since. Its understanding of a regiment of guideline principal is most fundamental to grasping rationalism itself. Descartes left several things out of his medium-line of reasoning, in particular, his analysis of God and his lack of defining the interconnection between the sensory and rational world. Other proponents of rationalism would attempt to rectify these problems as rationalism was developed as to simplify a philosophic system after Descartes.
Another famous rationalist, Baruch Spinoza, expanded upon the basic principal of rationalism. His philosophy entered on several principal, most of which relied on his notion that God was the only absolute substance; this idea is very similar to Descartes' conception of God. Spinoza argued that God was a substance composed of two attributes: thought and extension. ‘Substance’ in Spinoza's view is something actual, eternal and perceived by the intellect. Any attributes that a substance has define its essence.
Spinoza also defined the term ‘mode‘ in his philosophy to be any variations or modification of that basic substance; essentially they are different forms of a similar thing. He believed that man and all aspects of the natural world were modes of the eternal substance of God. God can only be known through pure thought. This fact is distinctly rationalist; Spinoza thought that the only eternal substance could be known via reason alone, not sensory evidence. Through ethics, then, Spinoza believed that all moral behaviour could only be defined by the fact that we were variations on the definitions, so morality had to come through a definition of God's essence.
Gottfried Leibniz was another famous rationalist. Determined to rectify some problems that were not ratified by Descartes, he explored certain Aristotelian notions and attempted to combine Descartes' work with Aristotle's concept of form. He so believed that ideas exist in the intellect innately, however through his virtuality that established a sense that it is only when the mind reflects upon its own Beingness that it soon becomes actualized. Most of what is real of the substance, the real from Leibniz's point of view, which is the ‘monad.’ Monads are not things of extension, or have the continuance through succession and bring forth a progressive expansion, moreover, all without any supplementary delay. Every bit as their similarity is built upon the same edifice under which is to its supporting structure by which Spinoza, in addition to the many things that include of its strengthening activity, may consist of representational states that are pleasantly apperceptive in their boasting representations that peak within their existent force fields of consciousness. All activity that is represented in the monads is regulated by God, a being that is also a ‘monad.’
Rationalism relies on the idea that reality has a rational structure in that all aspects of it can be grasped through mathematical and logical principle and not simply sensory experience. Ethical and political principals are structures accorded of what is often given in agreement to the concepts of God as the absolute for moral conduct. The mind under this doctrine is not ‘a blank slate,’ thinking that these are not blank imprints seems positive, but show the evidence for providing senses of some functional details that evoke, least of mention, the principal by whom of responding to mathematical formulation and makes for methodological reason as exceptionally cognate.
It is not really as overwhelming that the philosophical/theological error that we call ‘modernism’ should begin with a dream. The dream, or actualities of self as perhaps are an arousing set of consecutive dreams, that happened on the night of November 10, 1619, the vigil of the Feast of St. Martin of Tours, under which a time of great feasting in the France of Rene Descartes' time. We are right to wonder whether Descartes ‘protests too much’, when he asserted in his autobiographical work that he had abstained from wine for some time before the night of his famous dreams. What he does admit, however, is that for several days before his experience, which would transform the basic orientation of philosophy, he had felt a ‘steady rise of temperature in his head.’
The young Descartes, some 23 years old when he found himself on that cold November night ‘shut up alone in a stove-heated room, had been quite an eccentric in his early years. Might there be of some controversy between English-speaking commentators about their concerns that regard of whether poles show that Descartes was ‘shut up in a stove-heated room’ or that he was ‘shut up in a stove,’ or whether of possibilities that might say that, ‘Dogs bark’ is true, or whether they simply say that, dogs bark, still might they say that the truth condition of ‘snow is white’ is that snow is white, also saying that ‘Britain would have capitulated had Hitler invaded’ is that Britain would have capitulated had Hitler invaded? These disputed elementary definition of running-on-the-spot disqualifies truth conditions from playing the central role in a substantive theory of meaning. It is, that Descartes' periodic intervals of general restlessness of spirit (not surprising if he were in the habit of shutting himself up in stoves) had manifested themselves during his adolescent years when he left behind his Jesuit schooling, of which he had a decidedly mixed impression, and ‘took up the book of the world.’ Tired of what he felt to be the endless intellectual discussions and controversies that taxed and left dubious the minds of so many, he put aside the reading of books and took up the practical matter of war, which the Central Europe of the early seventeenth century had made available to him as the 30 Years War between the forces of the Habsburg Catholic Holy Roman Emperor and those of the Protestant Princes of Northern Europe. It was as a ‘fighting man’ of the army of the Duke of Bavaria (although, no historic evidence had been given by Descartes, only for which he did not assert strongly of), that he found himself on that November day, holed up in a stove-heated room, wintering with the army in the German city of Ulm.
On this day, Descartes was meditating on the ‘disunity and uncertainty’ of his knowledge. Since his days at the Jesuit lycee [i.e., high-school/college] at La Fleche, he had marvelled at mathematics, especially geometry, a science in which he found certainty, necessity, and precision. How could he find a basis for all knowledge so that it might have the same unity and certainty as mathematics? Having in mind, for several years, a project and method to bring all the sciences together within the context of new universal philosophical ‘wisdom,’ Descartes interpreted the vivid dreams that he had connected along with the night of the Vigil of the Feast of St. Martin as a sign from God Himself. From that moment on, Descartes would believe that he had a divine mandate to establish an all-encompassing science of human wisdom. He himself was so convinced of this divine endorsement of his ‘mission,’ that he would make a pilgrimage to the Holy House of Loreto in Thanksgiving for this ‘favour.’
What could be the contextual representation as regarded to some immeasurable value of dreams, in that it promotes itself of the passions that are unformidably caused by the senses. However the objectivity, that its mission has taken to be so seriously that Descartes was ready to modulate all systems of thought developed before his own, perhaps, the exclusive passion of Scholasticism, was an owing requisite for his ‘pre-Philosophic.’
As for these dreams, it is the third that best expresses the original thought and intention of Rene Descartes' rationalism. During the dream that William Temple aptly calls, ‘the most disastrous moment in the history of Europe,’ Descartes saw before him two books. One was a dictionary, which appeared to him to be of little interest and use. The other was a compendium of poetry entitled Corpus Poetarum in which may have the quality of being a union of philosophy in the accompaniment of wisdom. Moreover, the way in which Descartes interpreted this dream set the stage for the rest of his life-long philosophical endeavours. For Descartes, the dictionary stood merely for the sciences gathered in their sterile and dry disconnection; the collection of poems marked more particularly and expressly the union of philosophy with wisdom. He shows that one should not be astonished that poets abound in utterances more weighty, and even more fulling is their meaning and fully expressed, than those found in the writings of philosophers. In each phraseological oddity enough there comes to the conclusion from of a man who would go down in history as the father of Rationalism. As justified by Descartes’ associates he comes through as the ‘marvel’ of wisdom, and to this, is with poets whose divine nature into which their inspiration and that dare have its phantasy. Only from which they’ll ‘strike out’ the seeds of enlightenment, they’re, is existing in the minds of all men like the sparking flames of awareness. By that of burning from the embers that once their glow gave into aflame, the fires of consciousness and their striking effortlessly indirect. Under which the more complacent came for itself, giving reason to posit for itself within the ease of philosophy. The written inscriptions by some professional philosophers of his time, have charged Descartes for failing to extend the assuring certainty for which the human urgency, and charismatic presentation with which we associate with the manifestations as capably organizing our knowledge and influencing our behavioural conduct.
It would be an unfortunate intellectual and historical mistake to take Rene Descartes for a relativist, who wished to undermine all certainty, along with dividing the individual sciences from each other into airtight compartments. That the contemporary result of Cartesian Rationalism has been nothing but relativism and the fragmentation of knowledge is, simply, the ironic outcome of Descartes' efforts toward the attainment of certainty and ‘universal mathematics.’ Here we must remember the traditional Aristotelian/Thomistic understanding that each specific science, e.g., botany and entomology had not only its own proper object of study (e.g., plants or insects), but, also, its own proper method of investigation and demonstration. This is why Descartes' insistence upon a single ‘universal’ method, resembling the method employed in geometry, are so destructive and disorienting. As we will be shown the clear and explicative comprehension for which the method that Descartes constructs to achieve scientific certainty, it was his departure from agreed upon philosophical principle and fundamental presuppositions that causes the philosophical trend he initiates to steer the post-Christian mind into the ditch of democratic relativism and religious indifferentism.
To clear an operated misconception about the thought of Rene Descartes will be needed to emphasize that although Mathematics, particularly the mathematical science of Geometry. They’re being for which collocated with to provisions for Descartes the general structure and procedure of his intellectual method, it must be remembered that Descartes did not at all view Mathematics as the highest and most intellectually efficacious science. Borrowed from the Mathematical ‘methods,’ which he defines as ‘reliable rules,’ that are easy to apply, and such that if one follows them exactly, one will never take what is false to be true or fruitlessly expend one's mental efforts, but will gradually and constantly invariant changes of the increasing abilities for ones knowledge (scientia) till one arrives at a true understanding within one's capacity. What disturbed Descartes about his own intellectual milieu was that men of learning were becoming specialists to the extent that they were forgetting achieving the state of ‘wisdom,’ which had traditionally been the objective of both philosopher and sage.
The image that Descartes used to portray his understanding of the new rationalist scientific ‘wisdom,’ was a tree, the ‘tree of wisdom.’ Every tree has three appearances, roots from which the tree is fixed to the ground and from which it gains its nourishment. The trunk of the tree that is the main quantitative mass of the tree and upholds the branches, and, finally, the branches that produce the flower or the fruit that both perpetuate the tree’s existence and expresses of the highest productive capabilities, and analogously from the tree, so to with the tree of philosophical and scientific knowledge. Descartes identifies the roots of the tree with metaphysics, especially the three most fundamental metaphysical concepts of God, the human thinking self, and the external material world. These three ideas, we can see the inevitable movement of Rationalism and all the philosophical schools related to it. The most fundamental realities in existence are spoken of and philosophically treated as ideas rather than things, provide the intellectual justification for the ‘trunk’ of the tree, a philosophically grounded physics that would give an account of all motions of quantitative being. The three branches, which Descartes speaks of, are the practical sciences of ethics, mechanics, and medicine. These three were the sciences, which Descartes felt had to be necessarily grounded in metaphysical knowledge, which would allow people to attain the goal that Descartes stated to be the primary goal of his new scientific method, making humanity the ‘master of nature.’
It is for us to see that, from the perspective of the perennial philosophical tradition, Descartes has inverted the very orientation of pedagogy and scientific speculation. In a very real way, Descartes' tree is ‘upside down.’ The practical arts and sciences should serve as the practical ‘ground’ (i.e., in the sense of providing for the necessary ordering of the physical and social realm of man) for the ultimate act of human intelligence that of intellectual contemplation of nature, the human soul, and most especially God. In Descartes' ‘Tree of Wisdom,’ the newly characterized ‘ideas’ of God, the human ‘self,’ and the external material world, are only the intellectually efficacious principles, which allow for the deduction of an entire system of truths derived from an analysis of the conceptual necessities inherent in the ‘ideas’ of God, the human thinking self, and the external material world themselves. In other words, what ought to be the highest object of intellectual contemplation -the goal and fruit of all scientific speculations become no more than a necessary intellectual step in a logical method that has as its intent the subjection of nature to the natural wishes and desires of man. It is interesting that Descartes had as one of his greatest hopes for his new rationalist science, the indefinite extension of a human longevity. That Descartes himself should have died at the young age of 54, after a short spell of cold weather in Stockholm, Sweden in 1650, foreshadowed the sterility of rationalist ‘first principles’ both in the speculative and in the practical domains.
What is prototypically necessitated, is how a system can be consenting by referring to by name ‘rationalism’ and, yet, appear prima facies to be so counterintuitive and irrational. Descartes' honest hope to derive all scientific knowledge concerning the structure and motions of the universe in a deductive way from three ‘self-evident’ ideas by simply analysing the conceptual necessities inherent in those ideas appears not only supremely irrational, but also downright fanciful. It is not surprising that the young scientist Huygens, who was both a physicist and an astronomer, along with being a contemporary of Descartes, saw nothing more in Descartes' great ‘scientific’ work Principes de la philosophe, than an extraordinarily interesting novel. What is even more irrational and counter-intuitive, which Descartes understood thoroughly as a necessity by which its deriving continence to this literal ‘universe?’ Scientific knowledge as based from the idea that Descartes had in himself these existing qualities as to assign a characteristic attribute or the condition from which some processes may have availabilities, least of mention, that individually purposive, must we then have our way of being to think. In every way, it is entirely guised for a thinking being, that may have its ways for any-one particular science, especially of ones own mind and by determining that the mind itself is, by conceiving its own ideas is likely clearer and distinctly certain to falsity and for what is true. Bringing into a different state by some sorted justification, for which are those of the Rationalists of the 17th and 18th centuries, upheld in teaching about humanly civilized intellectual autonomies. In that continues of both the absolute and that without the insignificant basis in any normal human experience. Moreover, one significant consequence of such a view of human knowledge was the rejection of all appeals to authority, both philosophical and dogmatic, in establishing intellectual certainty. Another part of the fall out of the Rationalist attack on the Thomistic synthesis of theological and philosophical learning, was the relegation of Theology, since it could not be derived from the idea of the thinking self, to the realm of ‘catechism,’ which was upheld solely based on faith. Thus, Cartesian Rationalism would relegate the believing man to a position of fideisms (i.e., an act of blind faith, unsupported or unsupportable by rational proof or argument).
Descartes’s theory of knowledge starts with the quest for certainty, for an indubitable starting-point or foundation on the basis alone of which progress is possible, however, the uses of hyperbolic doubt, or Cartesian doubt of investigating the extent of knowledge and its basis in reason or experience used by Descartes in the first two Meditations. It attempts to put knowledge upon a secure foundation by first inviting us to suspend judgement on any proposition whose truth can be doubted, as a bare possibility. The standards of acceptance are gradually raised as we are asked to doubt the deliverance of memory, the senses, and even reason, all of which can let us down. The process is eventually dramatized in the figure of the evil demon, or ‘malin génie,’ whose aim is to deceive us, so that our senses, memories and reasoning lead us astray. Making a request for then becomes one of finding some demon-proof points of certainty, and Descartes produces this in the famous ‘Cogito ergo sum,’ T think, therefore I am. It is on this slender basis that the correct use of our faculties has to be re-established, but apparently Descartes has denied himself any materials to use in reconstructing the edifice of knowledge. He has a basis, but no way of building on it without invoking principles that will not be demon-proof, and so will not meet the standards that has apparently set himself. Interpreting him as using is possible ‘clear and distinct ideas’ to prove the existence of God, whose benevolence e then justifies our use of clear and distinct ideas, e.g., ‘God is no deceiver,’ this is the notorious ‘Cartesian circle.’ Descartes’s own attitude to this problem is not quite, at times he seems more concerned with providing a stable body of knowledge that our natural faculties will endorse, than one that meets the more severe standards with which he starts. For example, in the second set of ‘Replies’ he shrugs off the possibility of ‘absolute falsity’ of our natural system of belief, in favour of our right to retain ‘any conviction so firm that it is quite incapable of being destroyed.’ The need to add such natural belief to anything certified by reason is eventually the cornerstone of Hume’s philosophy, in the basis of most 20th-century reactions to the method of doubt.
By locating the point of certainty in my own awareness of my own self, Descartes gives a first-person twist to the theory of knowledge that dominated the following centuries in spite of various counter-attacks speaking for social and public starting-points. The metaphysicians associated with this priority are the famous Cartesian dualism, or separation of mind and matter have two different but interacting substances. Descartes rigorously and rightly sees that it takes divine dispensation to certify any relationship between the two realms’ thus divided, nd to prove te reliability of the senses invokes a ‘clear and distinct perception’ of highly dubious proofs of the existence of a benevolent deity. Thus, has not net general acceptance: as Hume drily puts it, ‘to have recourse to the veracity of the supreme Being, to prove the veracity of our senses, is surely making a very unexpected circuit.’
In his own time Descartes’s conception of the entirely separate substance of the mind was recognized to cause insoluble problems of the nature of the caudal connection between the two. Although the theory of Occasionalism has never been widely popular, and in its application to the mind-body problem many philosophers would say that it was the result of misconceived Cartesian dualism. It also causes the problem, insoluble in its own terms, of ‘other minds.’ Descartes’s notorious denial that non-human animals are conscious is stark illustration of the problem. In his conception of matter, Descartes also gives preference to rational cogitation over anything derived from the senses. Since we can conceive chainages to its sensible qualities, matter is not an empirical concept, but eventually an entirely geometrical one, with extensions and motion as its only physical nature.
It is, nonetheless, adeptly derived of these foundational ‘first notions’ (i.e., of God, the thinking self, and the external material world) from which all the rest of human knowledge and science would be derived in an deductively fashion (i.e., before and exclusive of any sensible experience of the external natural world), the mind, according the Cartesian Method, needed to engage in two distinct processes. The first was analysis and the second was synthesis. Analysis involved ‘dividing up each difficulty that I was to examine into as many parts as possible and as seemed requisite. Descartes was convinced that he had followed this way of analysis (really, what should be called reductionism), in his most influential book, The Meditations on First Philosophy, by resolving the bounteous data of human knowledge and experience into the primary existential proposition, Cogito, ergo sum, i.e., I think, therefore, I am.
According to Descartes, all mental content could be reduced to three ‘innate’ (i.e., meaning ‘in born,’ that is, not gained by experience of the external world known through the senses) ideas, the idea that I have of myself, the idea I have of God, and the idea I have of materiality. These ideas were to be grasped with an absolute and certain intuition. By ‘intuition,’ Descartes meant a purely intellectual activity, and intellectual ‘seeing’ or ‘vision,’ which is so clear and distinct that it leaves no room for doubt. In another definition of intuition, Descartes said, ‘Intuition is the conception, without doubt, of an unclouded and attentive mind, which springs from rational analysis alone.’ It was from these primary and ‘irreducible’ ideas, which Cartesian Rationalism believed it could derive, through the intellectual process of deduction, all the content of human science and wisdom. That such an theoretical (i.e., that which is gained before and independent of concrete, sensible experience of the material world) conception of human science could ever pass itself off as ‘rationalism,’ is one of many ironies presented in the history of philosophy. Surely such counterintuitive gibber can only be explained by the Cartesian desire to establish the mind’s reasoning processes about which the foundation of the mind itself, rather than on a rational and lived encounter with a material created order that the mind necessarily recognizes to exist independently of the thinking ‘self.’
Several years have now since passed, when I realized how numerously faithless opinions that in my youth I had taken to be lawfully-begotten, and in such a way how doubtfully attributed were the subsequent constructs caused to be joined into a mass upon them. Thus I realized that once in my life I had to raze everything and begin again from the original foundations, if I wanted to establish anything firm and lasting in the sciences, in that providing those who follow this revolution are casually the entire orientation and objective philosophical study. As we have but to see Descartes' proposed intention toward becoming empty, in that which the edifice of his previously held opinions might be build upon those discredited misunderstands, as if by some new structural foundation that supports the possibility of some positional condition, least of mention, be that for out-of-the-ordinary is a contest that in every doubt there has been spoken by the Skeptics, under which it could possibly be among the misguided. It is the key to understanding Descartes, however, that we realize that he commenced his method to eliminate doubt by appealing to doubt. This Cartesian technique of employing doubt to achieve an overcoming of doubt and a putative certainty can be called a methodological doubt (i.e., it is a doubt employed so that all doubt can be overcome). The most important thing to notice here is that Descartes begins his philosophical reflection with doubt, rather than the wonder at the order of material creation that characterizes Aristotelian/Thomistic philosophy. Since Descartes realized that he could not analyse, in any reasonable amount of time, all of his opinions that he had newfound doubts about, he writes that: Nor therefore need I survey each opinion individually, a task that would be never-ending. Because of countervailing circumstances, the substructure of functional causation, in what of anytime can put up a reinforced edifice upon it, yet to crumble of its own accordance, so, then, I will attack of those principles that supported everything as I had once to believe.
What the death-defying crafts of Cartesian Doubt and Rationalism hits were the twin towers, of the Aristotelian philosophical system, (1) our trust that the ideas in our minds are simply perfect reflections of the perceived object in the natural world and (2) the understanding that the five senses give us a real and exact knowledge of the natures of things in the material world. These two attacks were definitely part of a philosophical jihad on Aristotle and his explanation of nature and the human mind and person, however, to forget this overarching anti-Aristotelian aim, would be to overlook the essence. In this regard, we must say that Descartes himself was more anti-Aristotelian than anti-Thomistic, since he admitted, near the end of his life, that he had never read St. Thomas' Summa Theologiae and, even, regretted the fact. What he knew about St. Thomas was, therefore, received second hand from his scholastic manuals and his Jesuit teachers.
Descartes tells us that it is the information supplied to us by sensation that is the primary object of attack in his attempt to ‘strike at the foundations’ of his former opinions. It was his ‘uncertainty’ about the reliability of the data of sensation and of the images in the imagination, which have their origin in the sensible species coming from sensation, that provoked him to state the following: ‘Surely whatever I had admitted until now as most true I received either from the senses or through the senses. However, I have noticed that the senses are sometimes deceptive. It is a mark of prudence never to place our complete trust in those who have deceived us even once.’ Following adhesive yet congestive conditions from which we are to conclude, if, in at all, to any drawn conclusions upon the observation made at the beginning of this essay, in that, we must, as much of Descartes' philosophical analysis correlated upon any relation by which Descartes himself, assails to the phenomenon of dreaming. At the end of the Meditation, Descartes states that it was the continual misjudgment that the mind warranty made throughout the relational and otherwise distribution of dynamic functional states that were of the dreams. Most undermining of his trust became the shape of future events, in that his sensible experience of the world and the surrounding surfaces about him. In Meditation one, Descartes states that his normal trust in the veracity of his mental experience of the sensible world was all ‘all right’ was I not a man who is accustomed to sleeping at night, and to experiencing in my dreams the very same things, or now and then even fewer plausible ones, as these insane people do when they are awake.
By inserting this slight doubt concerning the veracity of his sensible and imaginative experience, Descartes moved to the next stage of his method that was to state that, should I withhold my assent no less from an opinion that is not completely certain and unconditionally would I of those be patently false. Consequently, it will suffice for the rejection of all these opinions, if I find in each some reason for doubt. It would, therefore, for the sake of a procedural method supposed to yield only certain and specified knowledge. Descartes is going to reject as deceptive and distortive all his ideas that have their origin in sensation.
Descartes' mathematicians had against the probable will even turn themselves upon the science of mathematics, when, in his attempt to radicalize his methodological doubt, Descartes will postulate the idea of an evil genius. This ‘evil genius’ is used as a conceptual device to undermine our trust in the certainty of our judgments concerning mathematical truths. That 4+4=8 seems perfectly evident, with no serious reason for doubt. However, what if a being had created me who wanted to deceive me and he made me so that everything that I take to be absolutely certain is false. With this idea of a creative ‘evil genius,’ Descartes clears the mental field of all certain that could upstage his autonomous thinking self.
It is in Meditation two, where Descartes initiates the long-lasting trend, which we could name ‘philosophical modernism’ or ‘subjectivism,’ which bears its bitter fruit in the New Theology of the 20th century. It is here where we see the fatal ‘movement toward the thinking self,’ under which characterizes most of the philosophical movements endured of the last 350 years. It is, no doubt, fitting that Descartes use this counterintuitive idea of the ‘evil creative genius’, finally to achieve his one absolute certain truth, the truth that his own thinking mind exists, precisely just when he is thinking the idea ‘I exist.’ Descartes, is referring to the methodological device of the ‘evil genius’ states, ‘there is some deceiver or other who is supremely powerful and overshading shrewdness by whom in which are always deliberating deceive against me. Then there is no doubt that I exist, if he is deceiving me. Let him do his best at deception, he will never bring it about that I am nothing while I will think that I am something’. Descartes must exist, since even if there was such a thing as an ‘evil genius’ who is perpetually deceiving him, still he must exist to be deceived. The very fact of his possible complete deception is proof for the certain existence of the thinking self. Descartes has found his first certainty; he has established a new foundation for philosophy. For all those who follow in his wake, philosophy will have as its grounding human consciousness, and it will have as its subject matter the ideas present in the human mind.
Descartes, however, whatever the ultimate philosophical consequences of his ideas, did not want to fall into a position of solipsism (i.e., the philosophical position that states that the only things which one can know are the ideas in one's own mind). Yet to avoid this imprisoning subjectivism, Descartes needed to establish that there existed a being that had its existence independently of Descartes' own thinking self. He, also, needed to discover an ‘idea’ not subject to doubt, which would be conceptually rich enough to yield an entire physics of the material world. Descartes knew that the idea that he had of himself was as dominantly characterized by virtue of the enacting toward his thinking and willing of himself yet, was not enough. The only reality that could fit the bill was God Himself, and infinite, perfect, and all-powerful Being. However, an existent God for which is merely an idea, would not yield such results. Descartes', however, began an undertaking of Meditation three, given to turn, he was to provide some explanation as to the factual analysis that Descartes has had to an idea of God in his mind. In that, his God was truly existent and justifiably infinite, perfect, and the all-powerful Being. Even though, in doing this, Descartes uses a doubtless old argument called the ‘ontological argument.’ Nonetheless, it is the use of such an argument for resolving such profound and effectual charges against the modernity that philosophy and theology’s identified position for which their interconnection is or belongs to the idea of God.
Descartes' proof for the real existence of God, being restricted by his method to analysing his own ideas and not the created natural world around him, is that since he had an idea of a God who was an infinite and perfect being, that God must truly exist, since he, as a limited and imperfect thinking self, could not be the origin of the idea of an unlimited and perfect being. If there is to be an existent God, he would perhaps, be one who endures the unlimited and oversees our expansive universe as perfectly impervious, must he have inscribed all reasons, for that Descartes’ conditional state of mind, has taken to be his idea from which he becomes the activator of himself. Therefore, God must truly exist and he must exist independently of Descartes' thinking self.
Having secured the real existence of God, Descartes uses the perfection of God to deduce of his veracity (i.e., God does not lie). If it is against God's nature to be a deceitful evil genius, then I can imply that what I, His creature, perceives as ‘clear and distinct’ with my mind or what is told me by God-given ‘common sense’ (what Descartes calls the ‘teachings of nature’) from which it becomes the true and intuitively certain. One thing taught me by my ‘common sense’ is that the ideas that I have of the material world come to me from outside me. Since the Creator God is not a deceiver, we can imply that such a material world, independent of the thinking self, truly exists.
When at the end of Meditation (6), the last of the meditations, Descartes says, ‘Therefore I should no longer fear that those things that are daily shown me by the senses are false. On the contrary, the hyperbolic doubts of the last few days ought to be rejected as ludicrous,’ one is lead to believe that the created and uncreated orders, as they stood before the employment of the rationalist doubt, have now been reinforced as they were with the added note of ‘mathematical’ certainty. This initial impression is deceptive, however. Coming out from the employment of a universal and radical doubt, the basic realities, of God, man, and the natural material world have been transformed. Man has become a thinking thing. A thing that is philosophically and epistemologically restricted to analysis finds of itself its own ideas, in that the encompassing moderation related by its consciousness will seem as to over flow in the consumerist shopping mall.
The material, and perhaps, all physical theoretic correlations are taken to be an existence along the guide lines of something as already confronting us, how more real are the subjective matters and the opposing physical theories that are measures throughout the world that emerges from this doubt. Ours’ being the one under which Aristotle and St. Thomas gave in the spoken exchange, a world-view of quality values and essences from which we are the same in our motions and potential movement’s of persuasion. That the ‘cradle’ of every Being whereby it may prove of an indirect displacement for which in those might show of its complementarities, in why reasons that justify the intermittent intervals through which time will escape by unseen suspensions that radiate its remittance. The ending of all things can in this way be as one might say, that God Himself, as Descartes explicates too further explain that upon such a rational application, and by it’s very orientation that he centres of all applicable origins, that it seems almost immediate that he adjoins of a nucleated position, and can stand openly acquainted, perhaps, as toward a better understanding of what it should be, as he built upon an edifice of supporting fundamental and yet structural foundations that by exaggerated assertions that is visualizability, viewed through those of which are universally secured by supportive constructions that can only generate its orbited centre. This, of course, is in opposition from being orbital. The red rose has become, not to mention, as a thing to be marvelled at, but also a thing to be measured. Their illuminated aspects of some measurable nature are in those that must be taken seriously by modern science and education. Only from which we are merely those that can emphasize far and beyond of what nature can be measured by quantification and depreciative measure. The ghost of human consciousness floats from mall to machine.
It is the reality of God, however, which suffers the most abuse from Descartes' rationalist method, though it seems as if no one in the history of philosophy has ‘used’ God more extensively than does Descartes. Now, however, God is reduced to a ‘fruitful’ idea that helps Descartes achieve the practical scientific results that he is much in need for those who really are in want. When Nietzsche says that, echoing Hegel, that ‘God is dead,’ for which he is simply stating that the ‘idea’ of God, has slipped out, for good, of the consciousness of European Man. Justly as for caused latency, if in fact, that proves of being to exist of some non-committed presents, in other words, of his acknowledged death only causes of God’s owing recognition. The God known by the plenitude of his creation, always studiously avoided by Descartes' deductively mind, is thus banished and, therefore, hidden from the inquiring man’s reflective eye.
When considering the fallout from the Rationalist ‘razing’ of Scholastic philosophy in so much of the Christian World, more most be considered than merely the obvious subjectivism and encroaching relativism seen for the past 350 years. It was the point in which Descartes agreed with the Skeptics of his time, their rejection of the reliability of sensation as a foundation for understanding, which should concern us most and show the path of restoration ahead. Now, in the contemporary process of education, the young are being presented with mathematical reconstructions of the world around them. Having been reduced to its quantitative aspects, at least for the ‘hard sciences,’ the world of common human experience is ignored while reconstructed ‘models’ of reality are presented to the young mind. Since God, the real God and not the ‘idea’ of God of course, did not make man to interact, both physically and psychologically, with Cartesian models of things, there will necessarily be, and we might even say that it is a healthy sign of nature ‘revoking’ a lack of interest in such mathematical and scientific models by most students, and a mere mechanical, ‘problem solving’ habit for those who are ‘interested.’ Nothing resonates; nothing follows the grain of the created human embodied psyche. Is it surprising then that much of the ‘work’ which is done in the mathematically oriented disciplines has no long lasting impact on the emerging self-understanding of contemporary youth? To build bombs, it is useful; to build boys it is not.
To strike at Modernism, we must plunge into the very heart of the matter. If man is to gain both his theological, philosophical, political, and psychological balance, he must recover that hardy realm that Descartes banished. To take seriously, St. Thomas' teaching that all knowledge begins with sensation, that all our knowledge concerning the existence of real things depends first on our seeing, touching, tasting, smelling, and feeling them, such would be the beginning of a return to sanity. For the great Thomistic tradition, the soft, bitter, pungent, melodious aspects of the natural world give us both a knowledge of the existence and the nature of things, along with stepping-stones from creatures to Creator. Let the myriads of Cartesian Men have their ‘mastery of nature.’ For us, loving the gas station that stands on the spot where the yet once grew is hard.
It has been well said that ‘all the thoughts of men, from the beginning of the world until now, are linked together into one great chain’; yet the conception of the intellectual filiation of people expressed in these words may, perhaps, be more fitting metaphor. The thoughts of men are comparable to the leaves, flowers, and fruit upon the innumerable branches of a few great stems, fed by commingled and hidden roots. These stems bear the names of the half-a-dozen men, endowed with intellects of heroic force and clearness, to whom we are led, at whatever point of the world of thought the attempt to trace its history commences, just as following upon the small twigs of a tree to the branchlets that bear them, and tracing the branchlets to their supporting branches, bring us, eventually, to the bole.
It seems to me that the thinker who, more than any other, stands in the relation of such a stem toward the philosophy and the science of modernity, I mean, that if you lay hold of any chorological sequence from which in modern ways of thinking, either in the region of philosophy, or in that of science, you find the spirit of that thought, if not its form, to have been present in the mind of the great Frenchman.
There are some men who are counted great because they represent the actuality of their own age, and mirror it as it is. Such an one was Voltaire, of whom it was epigrammatically said, ‘he expressed everybody's thoughts better than anybody.’ Nevertheless, there are other men who attain greatness because they embody the potentiality of their own day, and magically reflect the future. They express the thoughts that will be everybody's two or three centuries after them. Such an one was Descartes. Born in 1596, nearly three hundred years ago, of a noble family in Touraine, Réné Descartes grew up into a sickly and diminutive child, whose keen wit soon gained him that title of ‘the Philosopher, which, in the mouths of his noble blood relations, was more than half a reproach.
In whatever way that is to learn, by its intricate and evolving transactions are the moments whereby the temporary encompassment of consciousness and especially the strong forces of latency, where all things that have pasted are supported by the accumulating of thought, that we are to learn of its surface values, by that we have given to the derivatives in shape and types that are things of the foreseeable nurturing of natures conscious endeavours, that in all, we are to belong, when of a moment has released us upwards and as afar above for us to oversee upon the endless encircling circumference, as we are the endless circle with no end nor belong within to start a beginning as there is a given pease to the end. However, of all things that walk, breath and have their lives in Being, if be to contradiction it seems as enviably given comfort in the hope of what has of hope is that hope is hope for the wrong thing. If only to serve within some purposive allowance, as, perhaps, the dawning of something new is to some created promise by the coming of a world-view that, least of mention, might this that we are to walk upon the corpses of times generations for it is only to attest of what must be truth or a trued eventuality. Only of what is right, which is found by some kindred imagination, whereas, for the moment we draw from the summations that have travelled through space and time, that we are in belonging of our duty to man. All who are unable to satisfy their mental hunger must within the east wind of authority, be allowed in those of us who are immoderately in this position. So it is final, that the circle is now closed, and equations to eternity have all been resolved, and lastly, as it must be so, that the Universe is now complete.
It is one of Descartes' great claims to our reverence as a spiritual ancestor, who, at three-and-twenty, he saw clearly that this was his duty, and acted up to his conviction. At two-and-thirty, in fact, finding all other occupations incompatible with the search after the knowledge that leads to action, and being possessed of a modest achievement, he withdrew into Holland; where he spent nine years in learning and thinking, in such retirement that only one or two trusted friends knew of his whereabouts.
In 1637 the first-fruits of these long meditations were given to the world in the famous ‘Discourse touching the Method of using Reason rightly and of seeking Scientific Truth,’ which, at once an autobiography and a philosophy, clothes the deepest thought in language of exquisite harmony, simplicity, and clearness.
The central propositions of the whole ‘Discourse’ are these. There is a path that leads to truth so surely, that anyone who will reason, if entirely possible it must need to reach the goal, or grasp to its thought to the opinions reached, because, it must be to whether his capacities are great or small. There is one guiding rule by which a man may always find this path, and keep himself from straying when he has found it. This golden domineer is -permit no propositions but those that the truth is clear and distinct, in that they cannot be doubted.
The enunciation of this great first commandment of science consecrated Doubt. It removed Doubt from the seat of penance among the serious sins to which it had long been condemned, and enthroned it in that high place among the primary duties, which is assigned to it by the scientific conscience of these latter days. Descartes was the first among the moderns to obey this commandment deliberately. As a matter of religious duty, to strip off all his beliefs and reduce himself to a state of intellectual nakedness, until he could satisfy himself as fit to be issuing. He thought a bare skin healthier than the most respectable and well-cut clothing of what might, possibly, is mere shoddy.
When I say that Descartes consecrated doubt, you must remember that it was that sort of doubt that Goethe has called ‘the active scepticism,’ whose whole aim is to conquer itself. Not that other sort born of flippancy and ignorance, whose aim is only to perpetuate itself, as an excuse for idleness and indifference. Nevertheless, defining what is meant by scientific doubt better than in Descartes’ own words is impossible. After describing the gradual progress of his negative criticism, he tells us: For all that, I did not imitate the sceptics, who doubt only for doubting involvement, and pretend to be always undecided; on the contrary, my whole intention was to arrive at a certainty, and to dig away the drift and the sand until I reached the rock or the clay beneath. Further, since no man of common sense when he pulls down his house for rebuilding it, fails to give himself some shelter while the work is in successively proceeding. Further; so, before demolishing the spacious, if not spaciously mansions in his old beliefs, Descartes thought it wise to equip himself with what he calls ‘une morale par provision,’ this may resolve to govern his practical life until he could be better prepared. The laws of this provisional self-government are embodied in four maxims, of which one binds the philosopher to submit himself to the laws and religion through which he has brought up yet another, and to facilitate the function operatively, of which once he calls for an action, as, perhaps, might he promptly and according to the best of judgments, that he abides without repining, by that result, the third rule is to seek happiness in limiting his desires, of actions that seem of their attempting satisfactions, might he be, while the last is to make the search after truth as a business of his life.
Thus prepared to go on living while he doubted, Descartes continued to face his doubts like a man. One thing was clear to him, he would not lie to himself–would, under no penalties, say, ‘I am sure’ of that of which he was not sure; nonetheless its possibilities would go on digging and delving until he came to the solid adamant or, at worst, made sure there was no adamant. As the record of his progress tells us, he was obliged to confess that life is full of delusion, that authority may be in the wrong, in that its testimony may be false or mistaken, also for what reason lands us in endless fallacies, that our very immediate memories are as often less trustworthy as hope; that the evidence of the very senses may be misunderstood; that dreams are real as long since that they last, and that what we call reality may be a long and restless dream. Nay, it is conceivable that some powerful and malicious being may find his pleasure in deluding us, and in making us believe the thing that is not, every moment of our lives. What, then, are certain? What even, if such a being exists, is beyond the reach of his powers of delusion? Why, the fact that the thought, the present consciousness, exists. Our thoughts may be delusive, but they cannot be fictitious. As thoughts, they are real and existent, and the cleverest deceiver cannot make them otherwise.
Thus, thought is existence. More than that, so far as we are concerned, existence is thought, all our conceptions of existence being some kind or other of thought. Do not for a moment suppose that these are mere paradoxes or subtleties. A little reflection upon the commonest facts is irrefragable truth. For example, I take up a marble, and I find it to be a red, round, hard, single body. We call the redness, the roundness, the hardness, and the singleness, ‘qualities’ of the marble. It sounds, at first, that the highest sculpting form of absurdity might be to say that all these qualities are modes of our own consciousness, which cannot even be conceived to exist in the marble. Yet consider the redness, with which to begin. How does the sensation of redness arise? The waves of intuitive certainty, may it attenuated matter, the particles of which are vibrating with vast rapidity, but with very different velocities, strike upon the marble, and those that vibrate with a particular velocity are thrown off from its surface in all directions. The optical apparatus of the eye gathers some of these together, and gives them such a course that they impinge upon the surface of the retina, which is a singularly delicate apparatus connected with the end of the fibres of the optic nerve. The impulses of the attenuated matter, or ether, affect this apparatus and the fibres of the optic nerve in a certain way; and the change in the fibres of the optic nerve produces yet other changes in the brain; and these, in some fashion unknown to us, lead to the feeling, or consciousness of redness. If the marble could remain unchanged, and either the rate of vibration of the ether, or the nature of the retina, could be altered, the marble seems not red, but some other colour. There are many people who are what is called colour-blind, being unable to distinguish one colour from another. Such an one might declare our marble to be green. He would be quite as right in saying that it is green, as we are in declaring it to be red. Yet then, as the marble cannot can be both green and red, while, as this shows that the quality ‘redness’ must be of our consciousness and not in the marble.
In like manners, since the roundness and the hardness are forms of our consciousness is easy, belonging to the groups that we call sensations of sight and touch. If the surface of the cornea were cylindrical, we should have a very different notion of a round body from that which we possess now. If the strength of the fabric, and the force of the muscles of the body, were increased by some hundredfold, our proportional differences of consistency would possibly equal to that of some upcoming periphery where the marble would be as soft as a pellet of bread crumbs.
Not only is it obvious that all these qualities are in us, but, if you will try, you will find it quite impossible to conceive of ‘blueness,’ ‘roundness,’ and ‘hardness’ as existing without a call for such consciousness, his frame reference is to some such consciousness as our own. Saying that even the might seem strange ‘singleness’ of the marble is about us, but simple experiments will show that this is veritably the case, and that our two most trustworthy senses may be made to contradict one another on this notable point. Hold the marble between the finger and thumb, and look at it in the ordinary way. Sight and touch agree that it is single. Now squint, and sight tells you that there are two marbles, while touch asserts that there is only one. Next, return the eyes to their natural position, and, having crossed the forefinger and the middle finger, put the marble between their tips. Then touch will declare that there are two marbles, while the naked eye says that there is only one. Our sense of touch proclaims our belief, however when we appear to it, just as imperatively as the naked eye does.
Nevertheless, it may be said, the marble takes up a certain space that could not be occupied, while, by anything else. In other words, the marble has the primary quality of matter, extension. Surely this quality must be in the thing and not in our minds? Nonetheless, the reply must still be; whatever may, or may not, exist in the thing, all that we can know of these qualities is a state of consciousness. What we call extension is a consciousness of a relation between two, or more, affections of the sense of sight, or of touch. It is wholly inconceivable that what we call extension, is the branch of a progressional contingence and should exist independently of consciousness, as we knew it to be. Whether, this is inconceivability, it does so exist, or not, is a point on which I offer no opinion. Thus, whatever our marble may be, all that we can know of it is under the shape of a bundle of our own consciousness.
Nor is our knowledge of anything we know or feel more, or less, than a knowledge of states of consciousness. Our whole life is made up of such states. Some of these relational states as inferred by its cause we call ‘self’, and others to the cause or causes that may be comprehended under the title of ‘not-self.’ Nonetheless, inform that holds the existence neither of ‘self’ nor of that of which is ‘not-being-of-self’ have or can that we by any possibility have, any such unquestionable and immediate certainty, that we have of our relational states of consciousness, under which we can consider having been their effects. They are not immediately observed facts, but results of the application of the law of causation to those facts. Strictly speaking, the existence of a ‘self’ and of a ‘not-self’ are hypotheses by which we account for the facts of consciousness. They stand upon the same footing as the belief in the general trustworthiness of memory, and in the general constancy about A Nature-as hypothetical literature or academic summations for which acquires its doctorate to be acquainted and familiarized about its defending dissertation, only to be proven, or known with by way of its highest degree of certainty given by immediate consciousness, which, is, nevertheless, of the highest practical value, since the conclusions logically drawn are from them are always verifiably experienced.
This, in my judgment, is the ultimate issue of Descartes' argument, bearing to point out that we have left Descartes himself some way behind us. He stopped at the famous formula, ‘I think, therefore I am.’ Yet, the concerning considerations will show this formula to be full of intertwining fibres and verbal dissimulations that only assimilates entanglement. In the first place, the conclusive ly idealistic term said to be, ‘therefore’ which has no deserving business, and must legitimately find its way home. Also, ‘I am’ of being assume in that ‘I think’, may from which it is simply another way of saying ‘I am thinking’ or ‘I am conscious.’ All the same, it is in the second place, ‘I think’ which is not one simple proposition, it is, that there are three distinct assertions rolled into one. The first of these is, something called ‘I exist,’ the second is, something called ’thought exists’ and the third is, ‘the thought is the result of the action of I-ness.’
Now, it will be obvious to you, that the only one of these three propositions that can stand the Cartesian test of certainty is the second. It cannot be doubted, for the very doubt is an existent thought. However, the first and third, whether true or not, may be doubted, and have been doubted. For the assenter may be asked, How do you know that thought is not self-existent, or that a given thought is not to affect of its previous line of thinking, or given to something otherwise to some external power? A diversity of other questions, much more easily put than answered. Descartes, determined as he was to strip off all the garments that the intellect weaves for itself, forgot this gossamer shirt of the ‘self’ bringing of a greater detriment, and the ruin of his expression when he began to clothe himself again.
Nevertheless, it is beside my purpose to dwell upon the minor peculiarities of the Cartesian philosophy. All I wish to put clearly before your minds thus far, is that Descartes, having commenced by declaring doubt to be a duty, found certainty in consciousness alone; and that the necessary outcome of his views is what may properly be termed Idealism; namely, the doctrine that, whatever the universe may be, all we can know of it is the picture presented to us by consciousness. This picture may be a true likeness–though how this can be is inconceivable; It may have no more resemblance to its cause than one of Bach's fugues has to the person who is playing it, than a piece of poetry has to the mouth and lips of a reciter. It is enough for all the practical purposes of human existence if we find that our trust in the representations of consciousness is verified by results. That, by their help, we are enabled ‘to walk surefootedly in this life.’
Thus the method, or path that leads to truth, showed by Descartes, takes us straight to the Critical Idealism of his great successor Kant. It is that Idealism that declares the ultimate fact of all knowledge to be consciousness, or, in other words, a mental phenomenon. Consequently, affirms the highest of all certainties, and the only absolute certainty, to be the existence of mind. However, it is moreover that Idealism that refuses to make any speculative assertions, either positive or negative, find there parallel in what lies beyond consciousness. It accuses the subtle Berkeley of stepping beyond the limits of knowledge when he declared that a substance of matter does not exist. Existence may paradoxically be for not as the arguments for which he is supposed to have vanquished into the Northern sea, but reasons hold to its existence for the sake of matter itself, only from which we were equally destructive to the existence of soul. Nevertheless, it refuses to listen to the jargon of more recent days about the ‘Absolute’ and all the other hypostasised adjectives, the initial letters of the names of which is generally printed are the capital letters, just as you give a Grenadier a bearskin cap, it much seems as to give the appearance of ponderosity for more than he is by nature.
The path indicated and followed by Descartes, which we have previously been treading, leads through doubt to that critical Idealism that lies at the heart of modern metaphysical thought. Yet the ‘Discourse’ shows us another, and apparently very different, the path, which leads, quite as definitely, to that correlation of all the phenomena of the universe with matter and motion, which lies at the heart of modern physical thought, that most people call Materialism.
The early part of the seventeenth century, when Descartes reached manhood, is an epoch of the intellectual life of manhood. Then, physical science suddenly strode into the arena of public and familiar thought, and openly challenged not only Philosophy and the Church, but that common ignorance that often passes by the name of Common Sense. The assertion of the motion of the earth was a defiance to all three, and Physical Science threw down her glove by the hand of Galileo.
Thinking of the immediate result of the combat is not pleasant, to see the defender of science, old, worn, and on his knees before the Cardinal Inquisitor, signing his name to what only he knew to be a lie. No doubt, the Cardinals rubbed their hands as they thought of themselves to how well they had silenced and discredited their adversary. Still, two hundred years have passed, and have long since diminished of any but one feeble or erroneous combatant. Physical Science sits crowned and enthroned as one legitimate ruler of the world in thought. Charity children would be ashamed not to know that the earth moves; while the Schoolmen are forgotten; and the Cardinals–well, the Cardinals are at the Ecumenical Council, still at their old business of trying to stop the movement of the world.
According to Descartes, if we make errors in our thinking, it is our own fault. Human beings are given to a free will, and most substantially significant, and just a flawless part of our species. This free will acts independently to either affirm or deny, or pursue or shun any some thing. The free will acts properly when the will has access to knowledge and reason and can ‘perceive what is true with sufficient clarity and distinctness.’ To attain truth, and to act correctly, the will must rely on those perceptions that cannot come from anything, but rather, come from something, and that something must be from God in all his supreme perfection. God, in essence, must play the celestial orchestrator in any perception that is true. Following this path cannot lead one to err; that is, the path of humility that relies on one's God-given faculties and God himself to use the will properly.
On the other hand, if freedom calls of the will, it is confronted with something of which it has no knowledge, it will act indifferently. Without God and the knowledge of what is true, the will ‘easily turns away from the true and the good,’ leading to deception and sin. In addition, use of the will with only partial knowledge, that is, without full clarity and distinct perception based on knowledge, will also lead to error. Indifference and conjecturing or making speculative assertions are not true or false, it is a misuse of the will, even if by the change of chance it could possible take or give oneself of luck, the outcome happens upon the truth. The deliberation from illiteracy, is one who arrogantly relies only upon then immigrated transitions for which all unexcepted modulations in doings, occurs from those that are without truth only inaccessibly from God, thus, the make-upon of some unequivocal misuse of free will, are ultimately and undeniably, as merely of an error.
Spinoza would disagree with Descartes' idea of the free will. While the will for Descartes uses the intellect freely (in the proper way), Spinoza asserts that ‘things could not have been produced by God in any other way or in other order than is the case.’ The will is not a free cause, but a necessary cause, because it is only a ‘definite mode of thinking’ and thus subject to the greater causal matrix. Since all causes in the matrix can be followed back to God as an absolutely infinite being, everything has its cause in God. While, not even God has freedom of the will, as he is constrained by his divine nature and can only act as his nature would have it-the only way it can be as it is perfectly so. Therefore, there are no error, no sin, and no deception. Everything simply is as it should be according to the perfection of God's divine nature.
Substance is defined differently for Descartes, Spinoza and Leibniz contributing to the fundamental differences between their assertions in their philosophies. For Descartes, there are primarily three substances: God, thought and extension. For Spinoza there is only one substance: God. For Leibniz, there are two substances: God and monads. For each of these three, their concept of substance dramatically affects the outcomes of their philosophies and their explanations for the nature of the universe and our place in humanely, and we might consider ourselves as inseparable of it, and in our relation to God.
Descartes' determination foreshadows to carry through his need to readily rethink along everything he has ever thought to be True and Right. In doing so, he realizes that the only thing he can really be sure of is his ability to think, thus affirming his existence, and the substance of thought. He bears to witness in the conditions of truth that he is in himself from that which is a prefect God, and that God must be both omnipotent and benevolent. He can then determine that because God is not a great deceiver (deception is an attribute of imperfection not consistent with perfection), then extension is the third substance. There are some discussions regarding the ability of the two substances, thought and extension, to interact. Since effect can be caused by only the same kind of substance, having it of some connotation for being causally then seems impossible for thought and effectual of the body. However, Descartes asserts that at the smallest levels interaction does occur.
Spinoza criticizes Descartes for not following through on his assertions about an infinite God. If God is infinite, then he must be absolutely infinite, that is ‘substance consisting of infinite attributes, each of which expresses eternal and infinite essence.’ Because God is also perfect in his divine nature, everything that is, is by that perfection and is only exactly as it can be. God, thought and extensions are not separate substances, but rather thought and extension are simply attributes of God, expressed through an infinite amount of finite modalities. The order and connection between thoughts correspond and those for extended things (as they are the same) according to an infinite causal matrix determined by God, the only absolutely infinite substance.
Leibniz appeals to God as not only worthy of glory for his greatness and goodness, but his ability to create the most interesting reality from the simplest system. Leibniz proposes that God perpetuate this creation and by its infinite number in that of ‘monads.’ Each monads are a singular substance that ‘expresses the whole universe in its own way, and that all events, with all their circumstances and the whole sequence of external things, is included in its notion.’ There is a hierarchy of monads from the most simple and most confused, to the minds that are self-conscious and reflective, thus much less confused. When the perceptions of these infinite number of minds (monads) harmonize, the world arises as an emergent property based on well-founded phenomenons. Monads have no windows, that is, they do not interact. Nevertheless, again, they don't need to as each substance has within it a complete notion of itself. There is not a problem with the interaction of thought and extension, because there are only ‘monads.’
Knowledge for Locke is the perception of the agreement or disagreement of ideas. Ideas are the object of thinking, and come from sensation and reflection. It is the quality of a subject that has the power to produce ideas in one's mind. Experience provides the foundation for knowledge as observations about the sensible qualities of the external physical world are perceived through the senses and understanding of the internal operations of one's mind are operations of the mind. Both processes can be reflected upon in one's mind. Ideas are only received via these two methods. The sensation that people are exposed too in a lifetime will affect their ability to both sense and reflect, that is, if they are not exposed they can neither sense nor reflect on sensation they never received, and some people will remain more confused than others about their sense experience and reflection due to their (lack of) focussed and attentively purposed. Further, because reflection requires attention, ideas resulting from reflection only surface later, and, again, to different degrees among different people based on their varied perspective, focus and attention.
Simple ideas can be conceived by means of only one sense, more than one sense, by reflection only, or by all ways of sensation and reflection. Often these simple ideas don't even have a name. The mind is as an ‘empty cabinet’ ready for the passive reception of simple ideas. These simple ideas are neither created nor destroyed by the mind, but rather gathered into the mind through the senses or operations as such.
Leibniz believed the intelligible world of ultimate knowables, the problems raised by the skeptic Hume coming after him. He has some words to say to Descartes, who came before Leibniz, was of his concern of whether the world is knowable, but proving that knowledge of the external world is possible so, he foregoes the thrust of his philosophy. He focussed so much on what he believed must be true that stripped-down ideas that leave no point unquestioned, ultimately to prove knowledge impossible, or justify it only after the most extreme doubt possible, was not with what he was concerned. This sector will rather focus on Leibniz's rationalism -his idea that our main apparatus for discovering and understanding the nature of the world comes from pure reason, and not through the senses.
First, Leibniz believed it may have turned out that we did not know necessary truths such as ‘All green things are green.’ How is it that I know this proposition holds, even in some galaxy other than ours, on the other side of the universe? It was akin to a divine sort of magic to Leibniz that we should know any proposition that holds true under all circumstances and locations. He called it ‘an inborn light within us,’ which lets us cross the wide cosmos in one stroke of thought, and know beyond all doubt that all green things have always been green, no matter where on the earth or in the heavens, from the beginning of time to the end of the cosmos.
So let us examine just how we know that all green things are green. We know it because we know if a green thing is not green, it was an error to call it a green thing in the subject, and it is not in fact green. On the other hand, we know that if a thing is green, it is green. Ultimately to deny the proposition would involve us in a contradiction. Let us not forget, that if it is thus to suppose that all examined emeralds have been green. Uniformity would lead us to expect that future emeralds will be green as well. However, now we can define a predicate grue: ‘x’ is gruing if and only if ‘x’ is examined before time ’t’ and is green, or ‘x’ is examined after time ‘t’ and is blue. Let ‘t’ refers to some time around the present. Then if newly examined emeralds are like previous ones in respect of being grue, they will be blue. We prefer blueness as a basis of prediction to glueyness, but why? An interrogative sentence, by its appearing involvements as a reference to a difference, this is just a parochial or language-relative judgement, there brings no language-independent standard of similarity to which to appeal. Other philosophers have not been convinced by this degree of linguistic relativism. What remains clear is that the possibility of these ‘bent’ predicates puts a decisive obstacle in face of purely logical and syntactical approaches to problems of ‘confirmation.’ So we know now as well of the place that given to respect may not otherwise be true, or that there are such things as true contradictions. Nevertheless, we know there are no such things as true contradictions, and so we know that all green things are green.
Consequently the interrogative sentence comes to the boiling point from which its availabilities to answer of ‘how’ do we know there are no trued contradictions? We cannot prove this is true without assuming its truth in the first place, for any demonstration of any proposition is valid only if there are no true contradictions -the very things we are trying to prove. So to avoid begging the question, we cannot reason at all. That there are no true contradictions, then, cannot be demonstrated.
How do we know there are no true contradictions? That is, would we know it if it were merely a quirk of our minds that we cannot comprehend a true contradiction, some arbitrary way our brains developed, that has nothing to do with objective reality? Could it be that we cannot simply conceive of a true contradiction in the way that our bodies cannot be sustained by eating stones? Is it merely an arbitrary aspect of the human organism that we cannot conceive of a true contradiction, than this being due to the nature of the world itself?
One would never know this if it were so. We would go on reasoning and making rules of deductive logic that have nothing to do with what is true and false in nature itself, and only reflect arbitrary quirks of our psychological biology, so to speak, and what it can and cannot process as an organism that thinks.
Nevertheless, most philosophers do not think there is much fruit to be had in thinking like this. To question the rule of non-contradictorily, that is, to deny its truth, rests upon assuming its truth as much as asserting its truth does. Aristotle solved the problem by saying if a man doubts that there are no true contradictions, if he speaks and reasons, he is assuming the principle's truth; so if he questions it let him remain silent, but if he speaks and argues he must assume there are no true contradictions to do so, and thus undermines his doubt of the principle. Put another way: we have no choice but to assume there is no true contradiction if we are to philosophize at all; for whether we use reason to deny the rule of non-contradiction or to assert its truth we are all asserting its truth as a prerequisite. This very discussion of the problem assumes the rule's truth, and so where I question its validity here, ironically, I assert its veracity, by the mere fact that I am using reason.
So let us do what we must, and assume that it is complementary for the sake as drawn upon that we who infer that nature has some consistency of things. In themselves, we have in ruling of non-contradiction, for which case, are we to know of its truth? We, on the other hand, cannot explain in how we know it, only that we cannot conceive throughout in other respects. This is the ‘inborn light within us’ that allows us to cross time and space and know the nature of the other side of the cosmos, which Leibniz found so fascinating. Assuming the rule of non-contradiction is commentary on the true nature of things, it is certainly astounding that we should find a single principle that should apply to all places, times, dimensions and modes of being, from a mere act of thought. Certainly were the empiricist correct, but they would have a very difficult time explaining just how this ‘inborn light’ is possible. To say, that we have evolved as such as that we have become rationally ingested as to arrange by coordinative orders a set of communicative combinations that once had been lacking the ability to conceive of a true contradiction, into which realms are arbitrarily biological quirks, that place the origin set to a certain position that positioned by its growth was held steadfast within the strangest formalities as set through causality, least of mention, that, in so doing, its resulting consequent from arbitrary displacement drew nothing but a marginal peripheral infraction of nature. To do so would be to question the objective veracity of the principle; perhaps we can just survive and leave more offspring if we believed there were no true contradictions, though it is not in fact true that there are none. Certainly to call it a result of evolution is to deny the very veracity of the principle, something impossible in philosophy if it is to be philosophy. Evolution works by preserving the ones who leave the most offspring, not preserving the ones who know the most truth.
Before Kant, philosophy had two categories of knowledge: those propositions we know whose contrary implies a contradiction in terms, and those whose contrary didn't. ‘This apple is yellow’ doesn't have a contrary that implies a contradiction, while ‘All apples are apples’ does. Leibniz naturally found it more incredible that we could know the latter rather than the former; the former has no bearing on anything but that particular apple; it does not signify anything beyond the particular circumstance it describes. ‘All apples are apples,’ however, hold true from the foundation of the cosmos to its end, in every time and place there is. This was substantive knowledge to Leibniz. According to Leibniz it is the principle found in such universal knowledge that allowed us to use the senses, rather than the senses being the source of our knowledge. Without pure reason, to Leibniz, sense experience would be worthless; we could never progress in knowledge without the eternal principles of analytic reason, with which we analyse and process this sensory data. The senses are subject to doubt as well; they may all be dreams and fictions, while whether I am dreaming or awake if I think to myself ‘All apples are apples’ the proposition yet holds true, and I know it to be so, whether it occurs to me as I am dreaming, or hallucinating or whatever.
Sometimes a philosopher like Hume will propound a skepticism that makes us doubt whether we can even know what the philosopher himself is arguing, if he is right and we really know that little. But equally, empiricist like Hume betray the veracity of rationalism: Hume, after all, did not show us movies to teach us, he wrote books. If pure reason is worthless, and, least of mention, matters of the sense are only the avenues of our understanding, how is it we are to learn just by following Hume's path of reason? Wouldn't he do better to show us pictures and images? After all, all reasoning, Hume's reasoning even, comes in logical form, comes in words and not images, the stuff of thought. Hume's very enterprise of reasoning his way into showing reason worthless itself betrays the value of reason. Never mind that it was mostly inductive reason; if logic and pure reason were worthless, wherefore does Hume write, filling hundreds of pages of logical processes? We might say to him that he has an awful lot to say about what must be true, for someone who believes we cannot know the truth. In addition he employs logic and reasons quite extensively, for someone who believes pure reason can give us no substantive truth.
Leibniz saw quite correctly that, though sense experience is probably essential to human nature, and necessary for us to mature our minds in the first place, it is reason that gives us the perspective and principles to use such experiential sense-data. If I should know that a particular apple is green, and a thousand other data of the daily sights and sounds, without logic, reason and mathematics, by which I process and analyse and organize such data, none of our sciences would be possible, least of all philosophy, but the physical sciences of nature also. Sense-data contains the raw facts of the world, and, nonetheless, its found knowledge comes about when the principles in universal rules of reason are used to process such facts into knowing what we do not perceive, are they things like the centre of the Earth or the nature of the infant cosmos. Without universal principles, are they creative inductions like scientific theories, or the deductive rules of logic, sense data would get us nowhere—add fact to fact all one's life, without rational analysis, without using the tools of the ‘inborn light within us,’ and knowledge would be impossible. I am not so much arguing that was there no sense data there would be in fact knowledge, but only that both are required, that reason conductively deduces through sense-data and sense-data bears its fruit by means of reason, in a two-way process, both sides of which are often essential.
Psychologists today would no doubt insist that psychology be a discipline separate and distinct from that of philosophy. The mere fact that psychology is thought of as a science sets it apart from philosophy and, at times, makes it quite incompatible with philosophy. Yet psychology and philosophy are bound by history in that it is from philosophy that psychology receives the methods that psychology employs in analysing and evaluating the mind and all that it entails. Psychology owes its existence to most philosophical thinkers including Aristotle, Plato, John Locke, and David Hume. Here, our immediate focus on the particular influences of Rationalism, is specifically focussing on the work of René Descartes and the counterarguments of Emmanuel Kant.
René Descartes was a very private man and the details of his life are only vaguely known. Born in 1596, he was an intellectually bright child and was enrolled in the College at la Flèche at the age of 10. Some time after graduating at the age of sixteen, Descartes took up residence in the Paris suburb of St. Germain. Here, between periods of seclusion, Descartes observed the workings of a set of mechanical fountain statues built for the Queen. Watching these, he developed an idea that real bodies, animal and human, operate much like these automatautilizing a system of hydraulics and fluids to animate the body and its processes. This would be the basic idea involved in his later physiological theories of the brain and visual perceptivity (Fancher, 1979).
After moving and becomingly reclusive again, Descartes found himself dissatisfied with the uncertainties of much of the information he had learned in school and afterward. He was pleased with the certainties that mathematics offered, but as of yet there were not many ways to apply math to other disciplines. One morning during these frustrations, Descartes found himself watching a fly on the wall (or so the story goes) and suddenly discovered that he could define the fly’s position using only three numbers: the perpendicular distance of the fly from each wall and from the ceiling. Generalizing from this realization, he discovered that any point in space could be defined in a similar way by measuring their distances from perpendicular lines or planes. These numbers have commonly become known as ‘Cartesian coordinates’ and the perpendicular lines as the x -and y-axes. That discovery led to the development of analytical geometry, the first mathematical blending of algebra and geometry. The discovery of the coordinate plane, alone, is a huge contribution to psychology, for without it, defining the relationship between independent and dependent variables, calculating correlations, doing tests of significance, and other quantitative analysis would not be possible (Fancher, 1979)
After this discovery, Descartes began to wonder if there were other knowledge areas that could give answers or facts that provide the same amount of certainty as their results made to mathematics. Able to think of none, he proceeded with enumerating the faults of then-current scholarship and ultimately concluded that the best course for him to follow would be to disregard everything he had learned and only accept as ‘truth’ those things that he could determine were correct or valid through his own systematic reasoning. To this end, Descartes formed a method for such reasoning that he believed would offer other disciplines the same amount of certainty afforded by mathematics. This method consisted of four rules, stated briefly they are: (1) To proceed by means of doubt, to take nothing for granted, to avoid bias and prejudgment; (2) its distributive subject matter for which the argument becomes that which are the simplest parts; (3) as to the total proceeding in each related stage soon becomes the simple, and, of course, leading to the more complex; (4) To ‘enumerate’ and review to make sure nothing is missed in the argument, and that as many sources for the correct conclusion as possible may be collated.
Descartes was sure that this method would provide the mathematical elements needed to produce valid and reliable results in scholarly thinking. The first rule of this method, however, was especially troubling to Descartes. Already plagued with doubt about many other supposed truths, Descartes began to doubt everything until he even doubted that he existed. After a long process of doubting and reasoning, he doubted his existence until he realized the only thing he could no longer doubt was that he doubted. He reasoned that because he could not doubt that he was presently doubting, he must at least exist to be doubting. It is from this doubting, and subsequent realization and affirmation of existence we obtain the oft-quoted ‘I think, therefore I am,’ or ‘Cogito, ergo sum’ (Balz, 1952.) By proving that he existed, Descartes reasoned that he could also prove other things to be logically and rationally true by using the method he created.
Like the development of analytical geometry, the ideas contained in his methodology constitute a large contribution to the future of psychology in that it is precisely from the principles Descartes laid out in his method that deductive and inductive reasoning developed. What is more important, the introduction of methodology for the precise and systematic evaluation and verification if ideas or supposition was crucial to the development of the field of science, to an over-all picture, for much had been attributed to psychology? Descartes’ method provides the fundamental building blocks of the scientific method that modern science heralds as the marrow core in of all procedural guidelines. We, like Descartes, are satisfied that if all of the rules of the scientific method are followed exactly, the results should be valid and dependable.
Descartes made yet another important contribution to the future field of psychology immediately after his realization that he did exist. As he made this realization, he also realized that he could be sure that the mind and body were separate from one to conclude, in that I was a thing or substance whose whole essence or nature was only to think, and, to exist does not need space nor of any material thing or body. Thus, it follows that this ego, this mind, this soul, by which I am what I am, is entirely distinct from the body and am easier to know than the latter, and that even if the body were not, the soul would not cease to be all that it now is.
This was an important distinction at this time, for most of the discourse had concerned the workings of the soul with the assumption that the soul controlled most aspects of the body. It had been supposed that the soul was the seat of all reasoning, thought, memory, and so on, and the animating force within the body. It is not until Descartes that the mind is ascribed with the powers of reasoning, knowledge, and emotion separate from the functioning of the rest of the body. For Descartes, the body functions independently from the mind, however the mind and body can interact to produce varying results in behaviour. Although he does still discuss his mind as part of the soul, what is important is that Descartes uses and continues to develop the concept of the rational, thinking mind for being separate and distinct from the body. This mind-body distinction is obviously an important one for psychology, allowing for the development of much of physiological psychology with cognitive and perceptual psychology, among others.
This mind/body split led Descartes to make further conclusions about how the brain functioned. His primary concerns was the workings of vision and visual perception. Descartes concluded that, based on a previously discovered ‘truth’ that everything is in motion, light and objects give off tiny vibrations and these vibrations press upon various areas of the eye. This then causes the vibrations to move through the eye to stimulate a series of hollow nerves through which essential brain fluids flow. Much like the automata from St. Germain, Descartes envisioned that these brain fluids flowed through the nerves stimulated to constrict or expand by the vibrations of the objects being viewed so that a sort of stamp was of what was seen was created in the brain. Reasoning that because we have two eyes but only seem to perceive any object we are viewing as singular, he further concluded that there must be a centre in the brain in which the vibrations from both eyes meet to create a singular image. For Descartes, this area was the Pineal gland because it entered the brain and not lateralized like the rest of the brain. It was also here, he concluded, that the soul resided.
Although much of how Descartes reasoned, the mind to work was incorrect, some basic ideas were fundamental for future work on perception and physiological psychology. Among the important ideas is Descartes’ graphing of the visual field of perception that showed that each eye not only perceives what is directly in front of it, but also receives sense information from the outer field of the opposite eye (essentially that we see much in the left side of our visual field with our right eye and vice versa). Also, though he was wrong about the vibrations and hollow nerve tubes, he was correct in reasoning that there must be some centre in the brain where the images from both eyes are combined into a singular image to be consciously dealt with by the mind.
Descartes evidently had a profound impact on ways of thinking about the world and that this impact is still seen in much of modern psychology. However, these ideas in and of themselves did little to further the cause of Psychology, for Descartes’ method of ascertaining the truth by reason alone left out an entire realm of discussion that dealt not with how the senses perceived, but what the senses perceived. Indeed, the tenets of rationalism stated that sensory information was likely to be false and unreliable and summarily dismissed it from further discussion. There was a second group of thinkers, however, who viewed sensory information and experiences as the only accurate measurements of and indicators of ‘truth,’ as this group was called the empiricist.
Basic rationalism teaches of: (1) Don’t trust senses, since they sometimes mislead, knowingly; since the ‘knowledge’ they provide is inferior (because it changes; (2). Reason alone can provide knowledge. Math is the paradigm of real knowledge. (3) There are innate ideas, e.g., Plato’s Forms, or Descartes’ concepts of self, substance, and identity. (4) The self is real and discernable through immediate intellectual intuition (Cogito ergo sum). (5) Moral notions are comfortably grounded in an objective standard external to self -in God, or Form. Basic empirics’ precepts were as of (A) senses is the primary, or only, a source of knowledge of the world. Psychological atomism. (B). Mathematics deals only with relations of ideas (tautologies); gives no knowledge of the world. © No innate ideas (though Berkeley accepts Cartesian self). General or complex ideas are derived by abstraction from simple ones (conceptualism). (D). Hume -there’s no immediate intellectual intuition of self. The concept of ‘Self’ is not supported by sensations either. (E) Hume -no sensations support the notion of necessary connections between causes and effects, or the notion that the future will resemble the past. (F) Hume -‘is,’ that does not imply to ‘ought’ for each their source of morality is feeling.
Although both of thee schools of thought believed that truth was attainable, they disagreed about the role that the senses played in discovering this truth. The rationalists employed deductive reasoning, reasoning that does not depend on experience to inform it (for example concepts and constructs such as bachelor or death that do not require certain experiences to be understood) to attain truths. The empiricist utilized empirical reasoning, reasoning that depends upon experience or contingent events in the world to inform it (that George Bush, Jr. is president in 2004 cannot be determined by examining the concepts of ‘president’ and ‘George Bush’). This disagreement over which type of reasoning was superior continued until the 1780’s when Emmanuel Kant, a German philosopher, began publishing his most influential works.
Kant’s work was primarily a reaction against the work of the empiricist David Hume. He found problems with both the empiricist and the rationalists, however. Essentially Kant proposed that neither rationalism nor empiricism were sufficient, or correct, in determining absolute truths for there were truths that neither of these two schools could prove as such by only using inductively and theoretical reasoning. Moreover, both modes of thought contained flaws that allowed two contradictory statements, or autonomies, to both be accepted as true and valid.
Kant argues that while both rationalism and empiricism assume that obtaining knowledge of how things really are is possible, as opposed to how they seem to us, they overlook the fact that the human mind is limited. The human can experience and imagine only within certain constraints; the human mind has a hand in constructing and shaping our reality as we perceive and think about it. Specifically, these constraints are synthetic and deductively. Synthetic deductive truths, which include location in space and time, causality, experiencing self, thing-ness, and identity, does not depend on experience to be realized but also cannot be arrived at by the same kind of logical reasoning used by the rationalists. Neither of the two schools of thought was equipped to deal with these kinds of truths.
The solution to this problem, Kant argued, was to understand that the world we experience must be distinguished into two categories -the noumenal, or external world, and the phenomenal, or an internal world. The noumenal world consists of ‘things-in-themselves,’ objects, as they exist in their pure and unfiltered form. However, Kant warns, the noumenal world can never be known directly because once it is perceived by the human mind it passes into the phenomenal world. What humans experience is not the actual world, but a re-creation, an interactive experience, of the world (Fancher, 1979) In this way, Kant argues that the mind is an active agent in how we perceive and interact with the world; it creates reality just as much as it perceives it.
Through this argument, Kant creates a melding of the two schools of thought-rationalism and empiricism. He verifies the methods of the empiricists, in his agreement that of all that we perceive, think about, and thus know, is filtered through our senses and experience. Empiricism is complicated however, when Kant also insists that our mind create and interprets experience and ‘reality’ as it perceives it, and therefore rational reasoning must also be employed to ascertain several truths. It is only through combining these two methods that most truths may eventually be realized.
The extensive contributions of Descartes and the rationalists provided many ideas and distinctions that necessarily predicated Kant’s philosophical works. Especially important was the mind/body distinction and the development of the idea that mind and body could interact with one another. Kant, by arguing that a cohesive and valid science would not be possible unless the conditions of his synthetic deductive reasoning were met, encouraged, if not forced, the melding of the rationalist and empiricist modes of thought into one that allowed for both sensory experiences and reasoning, together, to provide the basis of ‘truth.’ However, perhaps the most important contribution to psychology is that all of this culminated in the new idea that the mind creates reality just as much as it perceives it. This idea paved the way for, indeed, created the need for a more exact study of the mind. With these new ideas in hand, and the previous obstacles to thinking removed, it would be less than a hundred years later that the first experimental psychology labs would be established and psychology would begin to flourish as a science.
Friedrich Nietzsche is not only one of the most influential philosophers the world has seen, but he is also one of the most controversial. He has influenced the twentieth century thought more than almost any other thinker. In his numerous works, Nietzsche constantly criticizes and restructures the strongly held philosophical and religious beliefs of his time. One such principle that he refutes belongs to his predecessor Rene' Descartes, and concerns the apparent distinction and significance of the human mind over the body. Descartes explains this elaborate theory in his Meditations on First Philosophy, claiming that the mind (the conscious) is the lone essential part of the human essence. On the other hand, Nietzsche stated via his manifestation through which all dynamic contributes are functionally of his distributive order as set further ahead by his work, On the Genealogy of Morality, his beliefs that the body (the unconscious) is key to the human essence. One may find it difficult to decide between these two ideas, for both philosophers pose good arguments on the contradicting sides of this famous dilemma.
However, by analysing them further, I realize that the qualities of their arguments are only as good as the foundations upon which they are based; one cannot have an understanding of the mind or the body without first having knowledge of the essence of human existence. Consequently, I will prove that the body is superior to the mind by showing that the centre for Nietzsche's ideas, the human essence, is more valid than that of Descartes.
Descartes' idea of the human essence is based solely on his formed concept of ‘radical doubt.’ He believes the essence of human existence to be simply ‘a thinking thing.’ We must now analyse how he arrived at this conclusion. Descartes is famous for radical doubt, a concept that questions everything, and assumes nothing to be true unless it can be proved so with his idea of ‘clear and distinct perception.’ From this he states that the only thing he can clearly and distinctively perceive is that ‘I exist.’ He concludes that since he ceases to exist when he ceases to think, he can then clearly and distinctively call himself a ‘thinking thing.’ Descartes explains this train of thought when he says: From the fact that I know that I exist, and that while I judge that obviously nothing else belongs to my nature or essence except that I am a thinking thing, I rightly conclude that my essence consists entirely in my being a thinking thing. Although perhaps I have a body that is very closely joined to me, nevertheless, because on the one hand I have a clear and distinct idea of myself, insofar as I am merely a thinking thing and not an extended thing, and because on the other hand I have a distinct idea of a body, insofar as it is merely an extended thing and not a thinking thing, it is certain that I am really distinct from my body, and can exist without it.
Descartes’ arrival of the human essence as a ‘thinking thing’ in this way is obviously fully based on his beliefs of radical doubt and clear and distinct perception. He bases all of his inferences on other inferences.
Descartes also devaluates the human body and places the mind at the essence of the human existence based on his concept. Due to his radical doubt, Descartes quickly omits the body and the entire physical world as having any significance because of the simple fact that they can be doubted. He establishes a strong sense of doubt in his senses, because, according to Descartes, one cannot know clearly and distinctly that they are not being deceived into their physical sensations. Descartes thus condemns the significance of the body when he proclaims that it is ‘not a substance endowed with understanding.’ He places the body into the physical, unintelligible realm of his concept of dualism, opposite from the thinking, knowledgeable realm. Descartes now acknowledges the body for being useful only within the limits of ‘moving from one place to another, of taking on various shapes, and so on.’ It is from this condemnation of the body into the physical, unintelligible realm that Descartes further places the mind on a pedestal, and at the essence of human existence. To him the mind is superior because it thinks, which is our essence. He explains this in the indented quote I have already cited, saying that the mind can exist without the body. Analysing things with radical doubt clearly finalizes all of Descartes' ideas.
Therefore, Descartes' argument is not valid because of the fact that it is solely derived from assumptions. His idea of the superiority of the mind is based on the assumption that humans are thinking things, which it is based on the assumption of clear and distinct perception, which is further based on the assumption that radical doubt is valid. Descartes' entire argument includes the use of clear and distinct perception, a concept that he concocted, to evaluate what is true and what is false. Dubbing something valid when it is absurd based on an assumption, let alone many assumptions. Subsequently, it is false to grant Descartes' ideas any relevance because they are derived by judging things on his basis. Steven J. Wagner, in his essay ‘Descartes's Arguments for Mind-Body Distinctness,’ lends us support, at which this point becomes of us, as of when we are to believe of its good or the contrarieties of bad, that the proponents as gestured by our understanding were by him to say of: ‘Descartes's procedure only makes good sense once we see it as a product of his system. Too much in Descartes depends on things that are far too wrong.’ He explains that Cartesian (Descartes' thinking) dualism and the Cartesian mind can only be supported along Cartesian lines. It requires little intelligence to prove a point when one bases their argument for it on invalid theories of their own fabrication. The superiority of the mind in the human essence, therefore, has not been clearly proven because its ideal is based on Descartes' numerous assumptions.
Nietzsche's idea of the human essence, on the other hand, clearly holds more validity than Descartes' because it is not based on assumed principles. Nietzsche believes the human essence to be one of the competition, survival and a will to power. Unlike Descartes, Nietzsche's ideal is based on a foundation of facts. He concocts his ideal mostly by observing nature and the world around him. Bertram M. Laing, in his essay ‘The Metaphysics of Nietzsche's Immoralism,’ explains Nietzsche's belief called the ‘organic process,’ whereas the world is ‘a continual distribution and redistribution of force or power.’ Nietzsche, like Freud, attempts to account for the function of consciousness considering the new understanding of unconscious mental functioning. Nietzsche distinguishes between himself and ‘older philosophers’ who do not appreciate the significance of unconscious metal functioning, while Freud distinguishes between the unconscious of philosophers and the unconscious of psychoanalysis. What is missing if the acknowledgement of Nietzsche as philosopher and psychologist whose ideas on unconscious mental functioning have very strong affinities with psychoanalysis, as Freud himself on a number of other occasions, come to acknowledging in a specific and detailed manner an important forerunner of psychoanalysis? Although Freud has stated that Nietzsche’s insights are close to psychoanalysis, very rarely will he state any details regarding the similarities.
At its present state as a specific individual science the awakening of moral observation has become necessary, and people can no longer be spared the cruel sight of the moral dissecting table and its knives and forceps. For here thee rules that science that asks after the origin and history of the so-called moral sensations. Freud ‘who puts aside all his feelings, even his human sympathy, and concentrates his mental forces on the single aim of performing the operation as skilfully as possible.’ [However it] the unconscious must be assumed to be the general basis of psychical life. The unconscious is the true psychical reality, which in its innermost nature it is very much unknown to us as the reality of the external world, and it is as incompletely presented by the data of consciousness as is the external world by the communications of our sense organs, . . . that apart from conscious there are also unconscious psychical processes.
Nietzsche goes on to discuss a number of unconscious thoughts, feelings and motivations that are involved I the feeling of pity. Such unconscious motivations are clearly repressed (inadmissible to consciousness), although the analogy of the foot slipping points to what is unconscious but would be admissible to consciousness. As this example to Nietzsche does not make the specific distinction, but his work is filled with explorations of our emotional states that are commonly regarded as selfless and highly moral but which he demonstrate are involved in our self-enjoyment and self-gratification. Our disguised expressions of sexuality and will to power, while unconsciously denying that this is so and assuaging conscience. Nietzsche was interested in ‘the diverse operations of the conscious and the instinctive.’ In a note from 1870 or 1871, he also wrote, though in a different sense than Freud, that ‘all growth in our knowledge arises out of the making conscious of the unconscious.’
Other than the specific distinction between these systems, every major point of Freud’s, both along with and beyond Lipps, had been explicitly discussed by Nietzsche. Nietzsche was aware of the distinction between unconscious processes that were and were not ‘inadmissible to consciousness.’ It is true that he doesn’t always specifically make the distinction, though he is clearly aware of it.
Nietzsche goes on to a number of unconscious thoughts, feelings and motivations that are involved in the feeling of pity. Such anconeous motivations are clearly repressed (inadmissible to consciousness), least of mention, Nietzsche does not make the distinction, but he writes of both kinds of conscious processes. We call also change one’s mind to that by some early age Nietzsche was interested in ‘the diverse operations of the conscious and the instinctive,’ up to this point he regards conscious and unconscious for their possessives as, ‘subject to different laws of development.’
He certainly did not believe that there was a realm of ‘the things-in-themselves’ as ‘a metaphor for the chaotic and unknowable true world that lay beyond perception.’ The real world is process and change for Nietzsche, as in his later works there is no ‘unknowable true world.’ For one thing, Nietzsche was attempting to get across the point that there is only one world, not two. And that for Nietzsche, if there is anything we contribute to the world, it is the idea of a ‘thing,’ and in Nietzsche’s words, the psychological origin of the belief in things forbids us to speak of ‘things-in-themselves,’ yet points out that in regard to the distinction between ‘appearance’ and ‘reality,’ and what he repudiates is the distinction between and separation of a merely apparent world and a world of ‘true being.’
Once, again, we can consider that Nietzsche clearly thought he uncovered some truths regarding the areas into which he had inquired, whether it be the origin of bad conscience or the psychological motivations of the Apostle Paul. Truth is not illusory but it does unavoidably entail perspectivity. For Nietzsche, the apparent world is not cut off from a world of absolute truth. While Nietzsche is quite willing as in his psychological exploration, to draw destinations between ‘deeper’ realities in relation to ‘surface’ appearances, he also argues that on a fundamental level one cannot draw a distinction between a merely apparent world and a perspective-free factual world. The ‘deeper’ realities he discovered cannot be regarded as facts-in-themselves or anything else of the kind that would be free of embeddedness in human schemes, practices, theories, and interpretations, of sortal perspectives seeing and knowing.
Although Nietzsche calls into question the absolute value of truth, values the illusions (the truthful illusions) of art that ae a stimulant to life, values masks, veils and even the creative lie, he also answers the call of truth. Truth calls to us, tempts us to unveil her. If we have integrity we will say ‘Yes’ to the hardest service, surrounding much that we hold dear, including our wishes ‘not to see . . . [what] . . . one does see. When the unveiling takes place to recognize as not truth (or women) in-itself but an appearance that is reality by way of a particular perspective, as one might regard this situation as, among other possibilities an opportunity for the creative play of our interpretive capacities, fo the creating and destroying of play, for a creative sublimation of the will to power. But none of this obviates our capacity to sometimes reach what can be reasonably regarded as truth. What it does involve, is for Nietzsche ‘neither a noumenal realm of adjudication for competing truth claims, and perhaps what is most important, Nietzsche introduces the notion that truth is a kind of human practice. This entails ‘local pragmatic truth, truths as good as though Nietzsche does posit transhistorical truth claims given as his claim regarding the will to power. Nietzsche is concerned with what corresponds to or fits the facts, but such facts are not established without a human contribution, without interpretation. Of course, for those for whom the tern ‘fact’ should entail a ‘halt before the factum brutum,’ there may be an objection to the use of such terms as ‘fact, reality,’ and so forth, in such a context.
Nietzsche observes society as a barbaric, predatory world that he separates it into two groups: one having ‘slave morality,’ and the other ‘master morality.’ Those who possess master morality, or noble morality, are the ones who live their lives instinctively by trying to achieve heightened power, often at the expense of others. These people, according to Nietzsche, he, are the active and productive members of society. They exude power and confidence, and prioritize success over popularity. They are the ones who gain the power in the ‘organic process.’ Nietzsche preaches for people to have this kind of morality, for he sees this as ‘good.’ On the other hand, those who possess slave morality are the ones who do not act instinctively and thus are weak. Their weakness is apparent by observing their lack of productivity and success. They became clever to compensate for not being powerful, doing things like congregating for chances of greater defence. These people, according to Nietzsche, developed ‘resentment’ toward their superiors' power. Nietzsche thus calls them ‘the regression of humankind,’ because their morality develops out of hatred and a denial of our bodily instincts. The human essence, therefore, is one of some desires for power and success. Nietzsche cleverly legitimizes this claim by comparing it with the `survival of the fittest' aspects of nature. ‘Beasts of Prey’ hold the qualities of master morality, for they achieve their goals instinctively at the expense of their prey. They do what is needed for them to survive. Lambs, the prey, are equal to those included in Nietzsche's slave morality because they are weak, and congregate in herds for protection. The Beasts of Prey are obviously the ones who survive, so Nietzsche believes that we should strive to act instinctively like them. Rather than following the intimate steps that gaiting from Descartes' would lead by some trivial reason, it is clear that Nietzsche based his concoction of the human essence mostly on irrefutable observations. In this way his idea surpasses Descartes' in relevance and validity, thus giving him clear ground to employ this ideal in proving the superiority of the body.
Finally, Nietzsche uses this valid assertion of the human essence to prove that the body is essential to the human existence than the mind. Nietzsche argues that since the human essence is based on a predatory competition necessary in the ‘organic process’ of the world, the body is more important than the mind. Instinct, he says, is rooted in the body that we are given. Thus our bodies define who we are because they determine to what morality, masters or slave, we cohere. Nietzsche believes that one's placement within these categories is decided at birth as an unalterable ‘assignment’ determined by the genealogy of a person's morals. Our bodies determine whether we act according to our natural instincts for success and the will of power (master morality), or if we turn away from them (mutualist morality). These bodily instincts are the key element to our existence, for they completely govern our personalities. By analysing the Beasts of Prey argument again, it is clear that the lambs were born into their existence as preemptively instinctual, and as well as, primitively defensive from which is in as much as ado about its own obviousness for only being duly given to the physically structured consistency. The bodies of birds have also held to an estranged dissimulation, as of their unmannered instinct. It is likewise that this substantiates the body and is therefore the principal element of our existence. It is the difference between eating, and getting eaten, that Bertram M. Laing describes Nietzsche's ‘body’ when she calls it ‘the source of all inspiration; the power that breathes or speaks through one is not an alien deity, but the self, the man as he really is.’ The body, then, is superior to the mind, because it holds our natural instincts that fully determine who we are and how we will fare in the ‘organic process’ of our existence.
Nietzsche writes: ‘The evidence of the body reveals itself of a tremendous multiplicity,’ Also, ‘Suppose all unity were unity only as an organization? But the thing in which we believe was only invented as a foundation for the various attributes. Similarly: ‘The ‘subject’ is the fiction that many similar states in us are the effect of one substratum.’ Also, for Nietzsche there is no ‘I’ which thinks as a separate entity from the relations which persons have to the world in general. Nietzsche denies that one can suppose any inner thing are from its expressions in relationships. Unity can be attained to a degree, and such unity is highly valued by Nietzsche. But there is no perfect unity through self-creation nor one fixed true self, conscious or unconscious, waiting to be uncovered. And the structure of any ruling unity may at the same time be open to creative self-conflict and possible transformation -: If we are to ‘become who will open ourselves to ‘unremitting transformation -: you must, within a short space of time, pass though and throughout many individuals. The means are unremitting struggles.’ If we allow ourselves to have access to, and develop and utilize, more affects and more eyes, different eyes, we may be on the way to passing though and throughout many individuals. Such possibilities may be both potentially enriching and dangerous.
Had Wittgenstein ever had at any time feel to have to do with to write about himself, this apparently most ‘intellectuals’ of philosophers might have said: I have always thought with my whole body and my whole life. I do not know what purely intellectual problems are. You know these things by way of thinking, yet your thought is not your experience but the reverberation of the experience of others, as your room trembles when a carriage passes. I am sitting in that carriage, and as often, I am the carriage.
Although written by Nietzsche, Wittgenstein’s work is none the less suffused with authentic pathos, and it will be seen as an integral pat of the tragically self-destructive design of European thought.
In the First Meditation, Rene Descartes is to bring of a certain state, the question what he knows. He convinces himself that his senses cannot be trusted and that all his experiences may be nothing more than mere dreams. Descartes finally concludes that he may not know anything, not even the fact that he has a physical body
His Second Meditation focuses on the finding, in at least, of a single truth, or the intuitive certainty under which he can hold onto. In his quest for this certainty, Descartes rejects ‘whatever admits of the least doubt, just as if [he] found it to be wholly false.’ He even concedes perhaps ‘that nothing is.’ But Descartes is not so easily defeated. He convinces himself that he exists as a thing that thinks, in other words, a ‘thinking thing.’
How does Descartes reach such an unyielding conclusion? He first proves that despite all his uncertainties, he actually exists. His notion that all physical objects do not exist precludes him from having a body to prove his existence. Instead, Descartes argues that due to the very fact that he has these notions prove that ‘I’ exist. ‘But if I did convince myself of anything, I must have existed.’ He argues that even if deceived by and all-power being then he must also exist because, ‘[the deceiver] will never bring it about that, at the time of thinking that I am something, I am in fact nothing.’ Thus Descartes concludes that ‘I am’, ‘I exist’ is necessarily true whenever he conceives it in his head.
But what does Descartes mean by his expressing gesture of ‘I-ness’, of course, as might be expected, it was meant for himself. It certainly cannot be a body since he believes all physical objects to be mere illusions. Without the body, there can be no such things as nutrition, location motion or sensation. The only immovable attribute he can find that does not require his physical body is his consciousness or experience. He goes far to say that ‘maybe, if I wholly ceased from experiencing, I should at once wholly ceases to be.’ Furthermore, he says that ‘‘I am’ precisely taken refers only to a conscious being; that is a mind, a soul, an intellect, a reason.’ It is this consciousness that allows him see what is necessarily true. He argues that physical objects and attributes are not really perceived by the senses, but only by intellect and by being understood. Descartes concludes his argument by suggesting that it be as obviously perceived by his own mind through intellect and understanding. Thus he proves he knows that he exists of a thinking thing that experiences.
There are many different points in Descartes’ arguments. Some are more powerful than others but I believe his construct of an all-powerful deceiver is a pervasive one. He uses the evil spirit argument quite well to prove his own existence. I think where he fails adequately to defend his argument is proving that he is a being of consciousness and thus being able to think. For the remainder of this report, I will assume the existence of an evil spirit that deceives him.
He successfully defends that even if an evil spirit were deceiving him, he must undoubtedly exists. I agree with Descartes because if he did not exist, there would be nothing to deceive. So, if there is an evil spirit out to deceive him, he must exist. I agree that he has proven that he is at least a ‘thing’ but not yet of a ‘thinking thing.’
This brings us to the question of what does it mean to think? Descartes firmly believes that he is ‘a being that doubts, understands, asserts, denies, is willing, is unwilling; further that has sense and imagination.’ He asks the following rhetorical questions to build support his argument: ‘How can any of these things be less of a fact than my existence? Are there any in these of something distinct from consciousness? Can any of them be called a separate thing from myself?’ What Descartes fails to address is that perhaps the evil spirit tricks him into thinking that he has doubts, of which he understands and so forth. What and then? Does he still know he exists? Yes. Is he still a being with consciousness? Perhaps. Is he a thinking thing? Definitely not.
We already know that we can defend existence with the presence of the evil spirit as described earlier in this paper. He may or may not be a being of consciousness because he may be deceived of the thoughts that lead him to believe that he is conscious. But one might argue that even if he has been deceived that he is conscious then he is. Consequently, I will continue within a framed mind that any assumption that he is conscious being of, sets, least of mention, onto their indirective crystallized assumptions, as sharply as not for a thinking thing. To be the thinking thing that he claims at the end of the meditation would imply that he can perceive by intellect and understanding. However, the evil spirit has deceived him on those matters. He has neither the intellect nor the capacity to understand and thus to perceive. Furthermore, by inverting his argument ‘that nothing is more easily or manifestly perceptible to me than my own mind’ we can suggest that since he cannot perceive his own mind, he cannot exist.
But this raises a contradiction, has already been stated that his existence has been defended in the presence of an evil spirit. So is my last assertion invalid? Indeed it is because I have assumed that the mind and therefore existence can only be perceived through intellect and understanding as Descartes described. However, the mind need not be perceived by intellect nor understanding, it may be perceived due to deception caused by the evil spirit, thereby solving the contradiction. So, Descartes perception that he has intellect and understanding is caused by the evil spirit therefore he does not think.
What of consciousness? I have to reassume, if not for the moment through which time is an essential fraction for being humanly conscious. Some may argue that consciousness itself leads to thinking for consciousness cannot be without thinking. But just as I eluded sooner than expected, the reasons for believing he is conscious may be caused by the evil spirit. By Descartes’ own definition, a conscious being is one who doubts, understands and so on. However, if those doubts and understanding are not his own, but rather caused by an evil spirit, he does not really have those thoughts and feelings. And without those thoughts and feelings, he cannot be a conscious being. If he is not a conscious being, then he obviously cannot be a thinking thing. In short, the evil spirit can deceive Descartes into thinking he has consciousness when in fact he does not therefore he does not think.
So although we agree that Descartes can convince himself that ‘I am’, ‘I exist’, I do not agree that he has adequately shown that he is a thinking thing. I have shown that if the evil spirit deceives Descartes’ on perceived notion that he doubts, understands and so on, then Descartes has a false impression that he is conscious and therefore has a false impression about his ability to think. If the evil sprit does exist, Descartes can prove he exists but not as a thinking thing.
Descartes' human commitment to innate ideas places him in a rationalist tradition tracing back to Plato. Knowledge of the nature of reality derives from ideas of the intellect, not the senses. An important part of metaphysical inquiry therefore involves learning to think with the intellect. The allegory of the cave portrays this rationalist theme about epistemically distinct worlds. Plato likens what the senses reveal to shadowy imagery on the wall of a poorly lit cave -to brain images of mere figurine beings; he likens what the intellect reveals to a world of fully real beings illuminated by mental capacities. The metaphor aptly depicts our epistemic predicament, on Descartes' own doctrines. An important function of his methods is to help would-be Knowers redirect their attention from the confused imagery of the senses, to the luminous world of the intellect's clear and distinct ideas.
Further comparisons arise with Plato's doctrine of recollection. The Fifth Meditation comments of occupying -of having applied Cartesian methodology, thereby discovering innate truths within: ‘on first discovering them it seems that I am not so much learning something new as remembering before what I knew. Elsewhere Descartes adds, of innate truths: We come to know them by the power of our own native intelligence, without any sensory-data to go through. All geometrical truths are of this sort -not just the most obvious ones, but all the others, however abstruse they may appear. Hence, according to Plato, Socrates asks a slave boy about the elements of geometry and thereby makes the boy able to dig out certain truths from his own mind that he had not previously recognized were there, thus attempting to establish the doctrine of reminiscence. Our knowledge of God is of this sort.
The famous wax thought experiment of the Second Meditation is supposed to illustrate (among other things) of a procedural layout, from which it gives by saying it has underlying implications for being innate. The thought experiment purports to help the mediator achieve a purely mental recapitulation. Much more of an easily apprehending mode for it is the innate idea of body. According to Descartes, our minds come stocked with a variety of intellectual concepts -ideas whose content derives solely from the nature of the mind. This storehouse includes ideas in mathematics (e.g., number, line, a triangle), logic (e.g., contradiction, necessity), and metaphysics (e.g., identity, substance, causality). Interestingly, Descartes holds that even our sensory ideas involve innate content. On his understanding of the new mechanical physics, bodies have no real properties resembling our sensory ideas of colours, sounds, tastes, and the like, thus implying that the contentual ideas are drawn to bear out in the mind. Unlike purely intellectual concepts, however, the formation of these sensory ideas depends on sensory stimulation. I suggest that on Descartes' official doctrine, ideas are innate insofar as their content derives from the nature of the mind alone, as opposed to deriving from sense experience. This characterization allows that both intellectual and sensory concepts draw on native resources, though not to the same extent.
Though the subject of rationalism in Descartes' epistemology deserves careful attention, the present essay generally focuses on Descartes' efforts to achieve indefeasible Knowledge. Relatively little attention is given to his interesting doctrines of innateness, or, more generally, his ontology of thought.
Scholars have established many relations of Descartes' philosophy to medieval sources, as antidote to the supposition that the history of philosophy begins de novo with Descartes, though sometimes obscuring the difference between Cartesian, hence modern, philosophy and earlier thought. From the first appearance of the Cartesian philosophy, there was noted a remarkable similarity, especially respecting the Cogito, between Descartes and Augustine, and Arnauld then began a controversy in the fourth set of Objections to the Meditations 1, on which much has been written, especially in the twentieth century, the question whether Descartes' Cogito is or is not original to him. Nothing needs to be added to the side of kinship, nor to the side of difference in this controversy, than the two sides need to be drawn together to shed some light on the logic of the Cogito in both St. Augustine and Descartes, and the movement in thought from one to the other.
As any fair reading to the texts would show, both Descartes and Augustine find in the Cogito a deliverance from skepticism, then a movement from the Cogito to the spirituality of the soul, finally to an argument for God's existence. Yet there are also important differences, on the face of it, but as you are aware, it is, especially in the movement from the Cogito that knowledge of God's existence. Though both Augustine and Descartes required that we enter of ourselves into knowing that God exists, Augustine moves through eternal, immutable truths, such as the truths of mathematics, for him the standard whereby the human mind judges and higher than the temporal, changing human subject, to the unchangeable substance, God. There is present in Descartes, opposing such a proof, a theological presupposition of God's freedom and omnipotence extending as well to essences or ‘eternal truths’ as to existence, to the possibility as to reality, to truth as to being. This is the remarkable doctrine of the ‘creation of eternal truths,’ revealed by him directly in correspondence with Mersenne, later in the replies to the fifth and sixth set of objections to the Meditations, which appears obliquely in his published treatises in the extension of methodic doubt to the truths of mathematics and in the rejection of final causes. The Augustinian proof, since it moves through eternal truths in themselves dubitable acquired of a guarantee of the Divine veracity, would not for Descartes be valid.
Descartes' movement to the knowledge of God from the Cogito is through the idea of God, eternal, Infinite, immutable, omniscient, omnipotent, Creator of all things, also to have been regarded for being that whose celestial totality exists of itself in reasons that speak for saying, ‘just as it should be.’ The Law Maker, the idea, is, perhaps, more than is less or fewer than should be, is not, for which is born the thoughts that have power of neither additional nor supplementary attributions. That its essential essence of an idea is born infinitely contentual of its thought and is addressed through one who is imperfect, limited yet dependent. It is the only idea that is not by his attained upright position, so to speak, and is not brought forth through himself. For all other ideas are not very content by its superior realms to his thoughts. Yet he knows this idea not by a via negative, but positively, clearly and distinctly. That the Cartesian philosophy may come upon in the Cogito movement in this manner to knowledge of the existence of God, whether as in the Meditations to the cause of such an idea of God, or as in the Principles of Philosophy through an ontological argument, is foreign to the Augustinian philosophy. Though it is true that for Augustine as for Descartes the soul does have within itself an idea of God, still because of its weak and fallen nature, its mutability and finitude, it is by faith that it initially grasps the true idea of God as Trinity. The first admonition of Augustine, credo ut intelligas, is violated in the Cartesian procedure that begins solely with the ‘natural light’ of reason.

Nothing needs to be added to the side of kinship, nor to the side of difference in this controversy; rather the two sides need to be drawn together to shed some light on the logic of the Cogito in both St. Augustine and Descartes, and the movement in thought from one to the other. There is then this important difference in the Augustinian and Cartesian Cogito detected in the movement to the existence of God: in Augustine, it is a finding of exemplary ideas having a universality at variances with their being of a particular subject, a movement from a changeable subject to its underlying universality; the Cogito of Descartes is already apart from change, finds itself with universal ideas of which it feels perfectly competent to be the cause. For Descartes, only the idea of a perfect being surpasses it and gives it pauses, whereas Augustine's Cogito is not competent even to the ideas of mathematical truths.
Both forms of the Cogito are contra Academicos, and both forms affirm to the spirituality of the soul: As two rely upon their relationships. It ought not to be thought that the Augustinian or Cartesian argument against skepticism is merely destructive, that si fallor, sum or ego sum si me fallit simply refutes the sceptical position. Rather, the Cogito shows what the real error of skepticism is: it assumes the separation of thinking from its object; and in the same act it both reveals the fundamental ground of certainty and gives to thought a content appropriately its own. Mind thus remaining true to itself knows itself as a spiritual being and the content appropriate to it also as immaterial or idea. In these two respects the Cartesian Cogito and the Augustinian are in the closest harmony. But to this it must be noted that whereas for Augustine the Cogito occurs as part of the movement to scientia of matters revealed and held absolutely by faith, a movement that begins with a presupposition, the absolute standpoint of revealed truth, for Descartes the Cogito occurs as the absolute beginning. The Cartesian Cogito is more than a refutation of skepticism and an assertion of the pure spirituality of the soul; it is further the affirmation that nothing is acceptable to think which is not as clear and distinct as thought itself. As such, the Cartesian Cogito can ably give to the movement through which are the ontological arguments for God's existence, justly caused for only a Cogito is without a presupposition that makes possible the ultimate demand of argumentively conducted deductions, and, within the mind, appealing to nothing external. Finding within thought an idea of God to which necessary existence pertains just as clearly and distinctly as existence pertains to the thinking subject, its demand is fulfilled.
Certain differences in the philosophical standpoints of Descartes and St. Augustine are exemplified and take their origin in this difference in the Cogito as it occurs in the one and in the other. For both, knowledge through the senses is dubitable: in St. Augustine, because it is not immediate, for Descartes because its falsity is conceivable. Again in both there is a knowledge that is absolutely certain: For St. Augustine, it is because it is immediate, not by representation, for Descartes because its falsity is inconceivable. Thus, for Augustine ‘eternal truths,’ since unchangeable and immutable, are indubitable, whereas for Descartes, their truth is not immediate, but mediated through the knowledge of God's existence, and hence thought cannot by its own measure derive the truth of God's existence from them, their truth from God's existence.
It would be wrong to think of the Cartesian beginning with no other presupposition than thought alone as apart from all relation to the theology given more comprehensively in St. Augustine. It is rather the beginning of the philosophical reconstruction of that theology in finite subjectivity, that is, from the human standpoint. The Divine Revelations that must, with Augustine, be explicated at the outset, that the doctrine of the Trinity might be grasped as the fundamental doctrine of Christian faith, has by the seventeenth century informed human reason itself, the purgatio mentis has been effected. Modern philosophy, after the Christianization of those one thousand years has had its effect, takes into the finding that any presupposition superfluous and unworthy of the Divine Revelation itself, not through pride, but that the truth might reveal itself now as true.
Descartes' doctrine of the ‘creation of eternal truths,’ to which attention has been drawn, is a direct consequence of theological wisdom endeavouring to take seriously in its conception of Nature the Christian doctrine of Creation and the Divine Incarnation. Not content simply to grasp the ideal exemplars of nature, and their relation to God in the Divine Word, there is found in modern philosophy at least implicitly the need to know the activity of God in Creation. If at first this appears in Descartes as an unbalanced stress on God's freedom as purely volitional activity, as might be said of his first enunciation of the position in 1630 (this was the criticism of Mersenne), the position was tempered in the Meditations where the pure volitional activity of the genius malignus gives way to the idea of God, infinite power, infinite thought, infinite goodness.
An ontological argument, which is not found in Augustine, cannot fittingly be found there, where there is a Cogito and hence a grasp of a finite thinking about God, and yet a prior presupposition that cannot allow the Cogito its ultimate development. As the ontological argument occurs in Anselm, it occurs without a Cogito and hence admits of the further criticism of St. Thomas that the finite subjective element is an impediment and an element of which the concept of God must be divested, lest the concept be something merely in thought. Yet it is the most Trinitarian of arguments, as Anselm knew. A long development in making the belief in God one's own must occur from the thirteenth century to the dawn of modern philosophy before an ontological argument can be grasped as properly one's own. There is then this important

As to an idea, from which is infinitely to surpass all contentual implications that are representationally obtainable of their thoughts are inclined of being ingested for oneself, imperfect, limited, dependent. It is the only idea that is not his by right, so to speak, not begotten by himself, for all other ideas are not contentually superior to his thought. Yet he knows this idea not by a via negative, but positively, clearly and distinctly. That the Cartesian philosophy can in finding the Cogito movement in this manner, the knowledge sustained through the existence of God, whether as in the Meditations to the cause of such an idea of God, or as in the Principles of Philosophy through an ontological argument, is foreign to the Augustinian philosophy.

As the 19th century progressed, the problem of the relationship of mind to brain became ever more pressing. Indeed, so deep was the concern with mind/brain relations that it is difficult to find a systematic text written after 1860 that does not contain a discussion of this issue. Usually, this directly reflected two major developments that converged to impress philosophers and psychologists with the centrality of the mind/brain problem. The first of these involved progress in understanding the localization of cerebral function, based on the idea that the brain serves as the organ of mind. The second involved a growing familiarity with the thesis that mental events -beliefs, mental suggestions, mesmeric trance states, psychic traumas and the like -sometimes cause radical alterations in the state of the body. This change occurred as progress was made in understanding the nature of functional nervous disorders. Before proceeding further, we will briefly describe some major mind/brain perspectives articulated in response to these trends.
Although the theories of mind/brain relationship prevalent in the 19th century -epiphenomenalism, interactionism, dual-aspect monism, and mind stuff -were formulated in science, they, like their predecessors, were attempts to deal with the metaphysical complexities of the Cartesian impasse. It is not surprising, therefore, that these views evolved for the most part as variations on themes already addressed.
Prince was born in Boston and educated at Boston Latin, Harvard College, and Harvard Medical School. Inspired by the work of Chariot and Janet on hysteria, Liébeault and Bernheim on suggestion, Gurney on the hypnotic induction of dissociation, and James on automatic writing, Prince entered early upon the study of conscious and unconscious mental phenomena that was to become his life's work. Indeed, while he was still a medical student, he won the Boylston Prize for his graduation thesis, a treatise that eventually formed the core of The Nature of Mind and Human Automatism.
Like Mind and Human Automatism, Prince concerned himself with justifying the intuitive belief that our thoughts have something to do with the production of our actions. ‘No amount of reasoning,’ he wrote, ‘can argue me out of the belief that I drink this water because I am thirsty.’ After rejecting parallelism for being at variances with this intuition, Prince presented the classic formulation of the mind-stuff metaphysic: ‘instead of there being one substance with two properties or 'aspects,' -mind and motion, -there is one substance, mind; and the other apparent property, motion, is only the way in which this real substance, mind, is apprehended by a second organism: only the sensations of, or effect upon, the second organism, when acted upon (ideally) by the real substance, mind.’ For Prince, in other words, the psychical monism of mind-stuff constituted a modern form of immaterialism.
Like Prince, William James could never shake his conviction in the efficacy of mind, yet, is there to be some parallelled efficaciousness with Hodgson. Who during an early stage, exerted an influence over the development of James's thought. Even so, is there of any case that neither by him, who couldn’t escape from his belief in the reality and the efficacy of the brain. In 1890, when The Principles of Psychology was finally published, James devoted two chapters to the analysis and critique of contemporary mind/brain views, one to the automaton theory and another to the mind-stuff theory. Both chapters present extensive discussions of reasons for and against the views under analysis. The reader proceeding through the systematic dismantling of each of these views expects James, at any moment, to produce his own brilliant synthesis. Instead, however, even the redoubtable James, like many of those who had preceded him, found him confounded by the Cartesian impasse: ‘What shall we do? Many would find relief at this point in celebrating the mystery of the Unknowable and the 'awe' which we should feel at having such a principle to take final charge of our perplexities. Others would rejoice that the finite and separatist view of things with which we started with had, at last developed its contradictions, and was more or less to lead us dialectically upwards to some 'higher synthesis' in which inconsistencies cease from troubling and logic is at rest. It may be a constitutional infirmity, but I can take no comfort in such devices for making a luxury of intellectual defeat. They are but spiritual chloroform. Better live on the ragged edge, better gnaw the file forever’
James's ‘solution’ is to opt for a provisional and pragmatic empirical parallelism of the sort to which many psychologists still subscribe. The ‘simplest psycho-physic formula,’ he writes, ‘and the last word of a psychology that contents itself with verifiable laws, and seeks only to be clear, and to avoid unsafe hypotheses’ would be a ‘blank unmediated correspondence, term for term, of the succession of states of consciousness with the succession of total brain processes. . . .’ Beyond that, James suggests that we are unable to go at present without leaving the precincts of empirical science.
As the 19th century progressed, the problem of the relationship of mind to brain became especially acute as physiologists and psychologists began to focus on the nature and localization of cerebral function. In a diffuse and general way, the idea of functional localization had been available since antiquity. A notion of ‘soul’ globally related to the brain, for example, can be found in the work of Pythagoras, Hippocrates, Plato, Erisistratus, and Galen, among others. The pneumatic physiologists of the middle ages thought that mental capacities were located in the fluid of the ventricles. As belief in animal spirits died, however, so also did we give verification about any contradictory ventricularistic findings that would supplement each hypothesis made, and by 1784, when Jiri Prochaska published his de functionibus systematic nervosi, interest had shifted to the brain stem and cerebrum.
Despite these early views, the doctrine of functional localization proper, that the notion that specific mental processes are correlated with discrete regions of the brain and the attempt to establish localization by means of empirical observations were essentially 19th century achievement. The first critical steps toward those ends can be traced to the work of Franz Josef Gall (1758 -1828). Gall was born in Baden and studied medicine at Strasbourg and Vienna, where he received his degree in 1785. Impressed as a child by apparent correlations between unusual talents in his friends and striking variations in facial or cranial appearance, Gall set out to evolve a new cranioscopic method of localizing mental faculties. His first public lectures on a cranioscopy date from around 1796. Unfortunately, his lectures almost immediately aroused opposition on the grounds of his presumed materialism, and in 1805, he was forced to leave Vienna. After two years of travel, he arrived in Paris accompanied by his colleague, Johann Gaspar Spurzheim (1776-1832). In 1810, Gall and Spurzheim published the first volume of the Anatomie et Physiologie du système nerveux en général, Gall's most important contribution to neuroanatomy and the first major statement of his cranioscopy.
The essence of Gall's method of localization lay in correlating variations in character with variations in external craniological signs. The validity of this approach depended on three critical assumptions: that the size and shape of the cranium reflected the size and shape of the underlying portions of the cerebrum that mental abilities were innate and fixed, and that the relative level of development of an innate ability was a reflection of the inherited size of its cerebral organ. On these assumptions, an observed correlation between a particularly well developed ability and a particularly prominent area of the cranium could be interpreted as evidence of the functional localization of that ability in the correlative portion of the cerebrum.
