Through skepticism and doubt Descartes raised a simple yet complex question, what can I be certain of if I doubt everything? Struck by all of the falsehoods he had come to believe, Descartes set out to determine through reason what was certain and able to exist beyond doubt. In order for his habitual opinions and false knowledge to not interfere with his ability to perceive things as they truly were, Descartes doubted everything. In terms of the physical body, our senses tell us that there are external ligaments and matter that come together to produce a body. However, when we are skeptical and doubt all previous knowledge, we are then deceived by our senses and the physical body cannot be proven to exist. Even while doubting the existence of the physical body, Descartes was still able to project skepticism and have thoughts of doubt. There must have been a thinking thing thinking those doubts. For this reason, Descartes concluded that though he may not be certain that the physical body exists, he can be certain that he in fact does exist, “I am, then, in the strict since only a thinking thing that thinks,” (Cottingham 5). Thought has proven to be inseparable from “I” and there must be a self that exists. While nonmaterial, self is the intellect and faculty of thought. “I think, therefore I am,” Descartes concluded to be the single most certain fact and closest statement to an ultimate truth. We can doubt all previous knowledge and beliefs, but we cannot assume that we who are able to have thoughts such as doubts, do not exist.
Using his new concept of self as a thinking thing, Descartes further demonstrates this concept with a melting piece of wax. All of the features of the wax such as its smell, taste, sight, and touch that he...

...the existence of the mind they do accept mental events such as perceptions and feelings. These perceptions and feelings however are unobservable and we cannot know for sure that they last a lifetime. Remember, the self is supposed to be the essential part of a person that is consistent through time. There is no way of concluding that there is a self or even person if perceptions and feelings are unobservable with no way of knowing if they remain consistent through time. The thoughts of doubt that led Descartes to form the concept of self through, “I think, therefore I am,” cannot provide evidence of a self.

Through Descartes’s Meditations, he sought to reconstruct his life and the beliefs he had. He wanted to end up with beliefs that were completely justified and conclusively proven. In order to obtain his goal, Descartes had to doubt all of his foundational beliefs so that he could start over. This left Descartes doubting the reality of the world around him and even his own existence. In order to build up to new conclusively proven and justified true beliefs, Descartes needed a fixed and undeniable starting point. This starting point was his cogito, “I think, therefore I am.” In this paper I will argue that Descartes’s argument that he is definite of his own existence, is unsound.
To read Damasio's critique alongside Stephen Gaukroger's remarkably rich intellectual biography of Descartes, however, is to realize that Damasio could just as aptly have titled his book "Descartes' Vision." As Gaukroger points out, Descartes was reviled during his lifetime and for a century after his death not for his dualism but for his materialism. Only when the history of philosophy was rewritten in the nineteenth century as the story of epistemology did Descartes come to bear the double designation of being both the "father" of modern philosophy and the ranking nativist who visited upon us the catastrophic separation of mind from body and of reason from emotion. These labels are essentially caricatures that distort the actual complexity of what Descartes struggled to work out in his cognitive theory. Gaukroger reconstructs this struggle for us, sometimes on a month-by-month basis, showing how Descartes shuttled back and forth between an account of the body and the pursuit of the mind.
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).

Descartes claims there is a real distinction between the mind and body. In the Second Meditation the Meditator establishes his existence, that he is a thinking thing and the distinction between the mind and body. Descartes claims he is a thinking thing and since he can think he exists, same too with the mind. The mind is a thing that thinks therefore the mind exists. Using the method of doubt discussed in the First Meditation, Descartes is able to doubt the existence of the body but not the mind. Descartes cannot doubt that he has a mind , but can doubt he has a body therefore Descartes is a thinking thing and not a body. He can exists as a thinking thing without a body because the body's existence can be doubted.
The first step in rationalizing that your mind is separate from your body is to understand that you exist; that you are real. To prove that you actually exist, you must first entertain the thought “I don’t exist.” Since you are entertaining your thought, it’s real; therefore, if you’re thinking a real thought, you are real, too. There’s no way to doubt something, because the act of doubting makes you a doubter, which in turn makes you real. In the same way that thinking makes you a thinker. This is also known as Descartes famous dictum “logito ergo sum” or “I think, therefore, I am.” This suggests that we are “thinking things” or what Descartes refers to as “Res Cogitans.” Hence, you are your mind and not your body, and you can certainly exist without your body.
7 - What is the point of Descartes ' discussion of the piece of wax? That is, why does he talk about it?
Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.

By this I mean, that Descartes’ method of doubt is meant as a total destruction of all previously gleaned knowledge that can be put into doubt. However, there is a question as to whether or not this foundational destruction is intrinsically possible. Whether or not I doubt that I have a body, I still act as though I do, and I am raised in an environment with other people of the same species who are similarly embodied. Can I doubt that I have a body while simultaneously working to maintain its integrity? I claim that my actions belie my beliefs, that I do not truly doubt the belief in my body in the same way that I could doubt, for example, the existence of the Abominable
Rene Descartes decision to shatter the molds of traditional thinking is still talked about today. He is regarded as an influential abstract thinker; and some of his main ideas are still talked about by philosophers all over the world. While he wrote the "Meditations", he secluded himself from the outside world for a length of time, basically tore up his conventional thinking; and tried to come to some conclusion as to what was actually true and existing. In order to show that the sciences rest on firm foundations and that these foundations lay in the mind and not the senses, Descartes must begin by bringing into doubt all the beliefs that come to him by the senses. This is done in the first of six different steps that he named "Meditations" because of the state of mind he was in while he was contemplating all these different ideas. His six meditations are "One:Concerning those things that can be called into doubt", "Two:Concerning the Nature of the Human mind: that it is better known than the Body", "Three: Concerning God, that he exists", "Four: Concerning the True and the False", "Five: Concerning the Essence of Material things, and again concerning God, that he exists" and finally "Six: Concerning the Existence of Material things, and the real distinction between Mind and Body". Although all of these meditations are relevant and necessary to understand the complete work as a whole, the focus of this paper will be the first meditation.
rity and distinction, but we can conclude what Descartes means. He is saying that we can be sure that these primary qualities exist in bodies in the same way that they do in our ideas of bodies. This cannot be claimed for qualities such as heat, color, taste and smell, of which our ideas are so confused and vague that we must always reserve judgment. This can be seen in the wax example. Do you think that Descartes qualifies to your satisfaction that the mind and body are separate from each other?
