Recommended: Rene Descartes and his idea of knowledge
The topic of the mind and how do we know has been around since the beginning of time.
It is one of those questions that will most likely never be answered. I mean, the mind itself is so perplexing that we are still learning stuff about it daily. One question that Descartes proposed was “how do we know?” we still are pondering this one today. We ask it almost every day, maybe not in that way but in some form or another. So honestly, how do we know?
Whenever Descartes started studying about the mind he denounced all of his previous opinions and started fresh. He first stated that “knowledge is seen as a building in which all the superstructure is resting on a foundation, and the building is only as strong as its foundation” (Palmer 55). He wasn’t trying to prove that all of his previous opinions were false but rather try to stay away from the things that he did not know whether or not they were true. This technique was known as the methodological doubt. It has a motto which states: Everything is to be doubted.
This required Descartes to doubt anything and everything that he was not for sure of. He was looking for something that could not be doubted at all, the foundation of knowledge. He first went at this a very rushed manner but then he realized that maybe he was going at it a little to fast. After slowing down he went back and looked at what he had already looked at and thought this: “But it may be that although the senses sometimes deceive us concerning other thing which are hardly perceptible, or very far away, there are yet many others to be met with as to which we cannot reasonably have any doubt, although we recognize them by their means. For example, there is the fact that I am here. How should I deny that thes...

...him reach the truth. But he didn’t stop, he pushed on until he beat his dilemma. It was this mentality that helped him to succeed, he knew what he wanted to do and he wasn’t stopping until he achieved that.
Looking at all that Descartes did then one could say that he was a pretty successful person. He did what 95% of the world will never even be able to think about achieving in their lifetime. One could compare him to Bill Gates and say that he wasn’t as rich but I don’t think that Descartes really cared about riches. He had all that he had wanted and he was intellectually happy.

At the start of the meditation, Descartes begins by rejecting all his beliefs, so that he would not be deceived by any misconceptions from reaching the truth. Descartes acknowledges himself as, “a thing that thinks: that is, a thing that doubts, affirms, denies, understands a few things, is ignorant of many things” He is certain that that he thinks and exists because his knowledge and ideas are both ‘clear and distinct’. Descartes proposes a general rule, “that whatever one perceives very clearly and very distinctly is true” Descartes discovers, “that he can doubt what he clearly and distinctly perceives is true led to the realization that his first immediate priority should be to remove the doubt” because, “no organized body of knowledge is possible unless the doubt is removed” The best probable way to remove the doubt is prove that God exists, that he is not a deceiver and “will always guarantee that any clear and distinct ideas that enter our minds will be true.” Descartes must remove the threat of an invisible demon that inserts ideas and doubts into our minds to fool us , in order to rely on his ‘clear and distinct’ rule.
Baird and Kaufmann, the editors of our text, explain in their outline of Descartes' epistemology that the method by which the thinker carried out his philosophical work involved first discovering and being sure of a certainty, and then, from that certainty, reasoning what else it meant one could be sure of. He would admit nothing without being absolutely satisfied on his own (i.e., without being told so by others) that it was incontrovertible truth. This system was unique, according to the editors, in part because Descartes was not afraid to face doubt. Despite the fact that it was precisely doubt of which he was endeavoring to rid himself, he nonetheless allowed it the full reign it deserved and demanded over his intellectual labors. "Although uncertainty and doubt were the enemies," say Baird and Kaufmann (p.16), "Descartes hit upon the idea of using doubt as a tool or as a weapon. . . . He would use doubt as an acid to pour over every 'truth' to see if there was anything that could not be dissolved . . . ." This test, they explain, resulted for Descartes in the conclusion that, if he doubted everything in the world there was to doubt, it was still then certain that he was doubting; further, that in order to doubt, he had to exist. His own existence, therefore, was the first truth he could admit to with certainty, and it became the basis for the remainder of his epistemology.
In the second meditation, Descartes is searching for an Archimedian point on which to seed a pearl of certainty. By doubting everything in his first meditation, Descartes consequently doubts his own existence. It is here that a certainty is unearthed: “If I convinced myself of something then I certainly existed”(17). However, Descartes “does not deduce existence from thought by means of syllogism, but recognizes it as something self-evident by a simple intuition of the mind,” or in other words, by natural light (Second Replies:68).
In his work, Meditations on First Philosophy, Descartes narrates the search for certainty in order to recreate all knowledge. He begins with “radical doubt.” He asks a simple question “Is there any one thing of which we can be absolutely certain?” that provides the main question of his analysis. Proceeding forward, he states that the ground of his foundation is the self – evident knowledge of the “thinking thing,” which he himself is.
In the New Merriam Webster Dictionary, sophism is defined as a plausible but fallacious argument. In Rene Descartes Meditation V, he distinguishes the existence of God, believing he must prove that god exists before he can examine any corporeal objects outside of himself. By proving that the existence of God is not a sophism, he also argues that God is therefore the Supreme Being and the omnipotent one. His conclusion that God does exist enables him to prove the existence of material things, and the difference between the soul and the body.
Rene Descartes’ greatest work, Meditations on First Philosophy, attempts to build the base of knowledge through a skeptical point of view. In the First Meditation, Descartes argues that his knowledge has been built on reason and his senses, yet how does he know that those concepts are not deceiving him? He begins to doubt that his body exists, and compares himself to an insane person. What if he is delusional about his social ranking, or confused about the color of his clothes, or even unaware of the material that his head is made of? This is all because the senses are deceiving, even in our dreams we experience realistic visions and feelings. Finally, Descartes comes to the conclusion that everything must be doubted, and begins to build his

The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
using certain truths. To arrive at these truths Descartes doubted everything and especially could not trust authoritarian knowledge. This was known in the four "D's" as doctrine. The other three "D's" included the deceiving senses (empiricism), dreams (intuition), and demons (innate putting wrong ideas into our minds). Originally he doubted empirical thought because he could not even trust his senses. He used his senses only as a tool for doubting. Through doubting he felt that he could clear prejudices, which would allow him to arrive at certain truths. The goal of this destructive process was to find one clear and evident intuition that could be 100 percent certain. What he originally arrived at for a conclusion, was that everything could be doubted except doubting. However, to arrive at a truth he had to begin with a clear, evident intuition (an innate idea). This would be followed by moving from universals to particulars through deductive reasoning. He moved from the simple onto the complex incrementally, or step by step. He discovered the "I" to be the only certain truth, as his mind had to exist for him to be able to doubt. As stated earlier, Descartes truths had to begin with intuition, or an innate idea. This was the beginning of his constructive program of certainties. The first certainty wa...
In Meditations, Descartes brings doubt to everything he believes because it is human nature to believe that which is false. He states that most of what he believes comes from the senses and that a lot of times those senses can be deceived. His conclusion of doubting everything is based on his example of a basket of apples. It goes as follows; you have a basket of apples but you fear that some apples have gone bad and you don't want them to rot the others, so you throw all the apples out of the basket. Now that the basket is empty you examine each apple carefully and return the good apples to the basket. This is what he does with his beliefs, he follows and keeps only those beliefs of which he is sure of. Our beliefs as a whole must be discarded and then each individual belief must be looked at carefully before we can accept it. We must only accept those beliefs we feel are good.
since the existence of the mind could not be proven from the observation of behavior,
In Meditation Six entitled “Concerning the Existence of Material Things, and Real Distinction between the Mind and Body”, one important thing Descartes explores is the relationship between the mind and body. Descartes believes the mind and body are separated and they are two difference substances. He believes this to be clearly and distinctly true which is a Cartesian quality for true knowledge. I, on the other hand, disagree that the mind and body are separate and that the mind can exist without the body. First, I will present Descartes position on mind/body dualism and his proof for such ideas. Secondly, I will discuss why I think his argument is weak and offer my own ideas that dispute his reasoning while I keep in mind how he might dispute my argument.
Psychophysical dualism — the distinction between mind and body — is the counterposition between essentially irreducible elements: the mind and body. Such a dualism implies the main ontological problem of the philosophy of cognitive science and philosophy of mind: the mind-body problem (MBP). The dualism and the referred-to problem has been insistently discussed in the philosophical tradition and several solutions have been proposed. Such solutions are properly philosophical or require a scientific approach. First, I will expound the philosophical solution to the MBP proposed by Descartes, to be followed by an exposition of Ryle's criticisms to the solution. Second, from Ryle's criticism, I will deduce a scientific solution to the MBP related to the neural framework model of mind in cognitive science by means of what I call 'the principle of the embodiment of the mind.' Finally, I shall point out the philosophical difficulties that are to be found in using such a principle.
