A Method of Doubt and Descartes
In his first meditation, Descartes sets out with amazing clarity and persistence to clear himself of every false idea that he has acquired previous to this, and determine what he truly knows. To rid him of these "rotten apples" he has developed a method of doubt with a goal to construct a set of beliefs on foundations which are indubitable. On these foundations, Descartes applies three levels of skepticism, which in turn, generate three levels at which our thoughts may be deceived by error. Descartes states quite explicitly in the synopsis, that we can doubt all things which are material as long as "we have no foundations for the sciences other than those which we have had up till now"(synopsis:12). This skepticism also implies that doubt can free us from prejudices, enabling the mind to escape the deception of the senses, and possibly discover a truth which is beyond doubt. The first and main deception in Descartes opinion has evolved from sense perception "What ever I have up till now accepted as most true I have acquired either from the senses or through the sense. But from time to time I have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once"(1:18[13]). At the root of our beliefs, Descartes argues, lie the experiences we gain from our senses, because these are sometimes mistaken, as in the case of mirages or objects which appear small in the distance, and because of this he will now forfeit all of his most reliable information . More importantly it may be to follow in the steps of Plato and require knowledge that is certain and absolute ( Prado 1992 ). This argument consists of four main premises: 1. All that he has accepted as tru...

...nd necessary, "When Descartes begins to doubt in an epistemological mode, he cannot stop short of doubting whether Cartesian Doubt 9 he himself exists as a doubter" (Prado 1992). . Perhaps, when the poet Charles Bukowski said "the more crap you believe, the better off you are," he realized that such an extensive doubt can be harmful to the majority of people, because they are in fact "better off" believing in their senses, their God, and their ability to determine whether they are sleeping or awake. It is possible that it may be beneficial to live and die being deceived, and be ignorant to that deception, than to live and die searching for truth where truth may not be found, for the true determinant to whether such an extensive skepticism is beneficial or necessary depends on the individual. Neither Descartes nor Bukowski can speak for anyone other than themselves.
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.

Does Descartes give any good reason for saying that his mind could exist without his body?
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.
According to Descartes, “because our senses sometimes deceive us, I wanted to suppose that nothing was exactly as they led us to imagine (Descartes 18).” In order to extinguish his uncertainty and find incontrovertible truth, he chooses to “raze everything to the ground and begin again from the original foundations (Descartes 59).” This foundation, which Descartes is certain to be the absolute truth, is “I think, therefore I am (Descartes 18).” Descartes argues that truth and proof of reality lies in the human mind, rather than the senses. In other words, he claims that the existence of material objects are not based on the senses because of human imperfection. In fact, he argues that humans, similarly to Plato’s Allegory of the Cave, are incapable of sensing the true essence or existence of material objects. However, what makes an object real is human thought and the idea of that object, thus paving the way for Descartes’ proof of God’s existence. Because the senses are easily deceived and because Descartes understands that the senses can be deceived, Descartes is aware of his own imperfection. He
In Descartes’ Meditations on First Philosophy he proposes several arguments regarding human perception. He begins this exploration by examining the principles that his beliefs are founded on. By doing this, Descartes is choosing not to question each of his beliefs individually; he is choosing to examine the foundation of his perceptions. Descartes proceeds to question where he has attained his knowledge. The answer, he decides, is from his senses. Descartes also determines that there have been instances where his senses have been deceptive. It is from this idea that Descartes forms his deductions for Meditations I, II, and VI, and begins to question the concept of dualism.
In the first meditation, Descartes makes a conscious decision to search for “in each of them [his opinions] at least some reason for doubt”(12). Descartes rejects anything and everything that can be doubted and quests for something that is undeniably certain. The foundation of his doubt is that his opinions are largely established by his senses, yet “from time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(12). First, Descartes establishes that error is possible, employing the example of the straight stick that appears bent when partially submerged in water, as mentioned in the Sixth Replies (64-65). Secondly, he proves that at any given time he could be deceived, such is the case with realistic dreams. Further, Descartes is able to doubt absolutely everything since it cannot be ruled out that “some malicious demon … has employed all his energies in order to deceive me” (15). The malicious demon not only causes Descartes to doubt God, but also sends him “unexpectedly into a deep whirlpool which tumbles me around so that I can neither stand on the bottom or swim on the top”(16). Descartes has reached the point where he must begin to rebuild by searching for certainty.
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. Moving up the tower of certainty, he focuses on those ideas that can be supported by his original foundation. In such a way, Descartes’s goal is to establish all of human knowledge of firm foundations. Thus, Descartes gains this knowledge from the natural light by using it to reference his main claims, specifically
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.
Having faith is believing in things that you don’t see. According to the Meditations, Descartes gets rid of beliefs that he isn’t certain of and keeps the ones that are undoubtable. He tries to prove that God has must exist since we have such a clear and distinct idea of him. I believe it is impossible to prove without a doubt that God exists.
Philosophical context: I shall use Descartes’ Meditations 1 and Blackburn 's “Think” to discuss the question and my initial answer. In Meditations 1, Descartes sets out to destroy all preconceived notions from his childhood and establish a new foundation for the sciences -- a lasting foundation and explores methods of doubt to his own senses and how to deal with them properly.
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
Cartesian Skepticism, created by René Descartes, is the process of doubting ones’ beliefs of what they happen to consider as true in the hopes of uncovering the absolute truths in life. This methodology is used to distinguish between what is the truth and what is false, with anything that cannot be considered an absolute truth being considered a reasonable doubt. Anything which then becomes categorized as a reasonable doubt is perceived as false. As Descartes goes through this process, he then realizes that the one thing that can be considered an absolutely truth is his and every other individual’s existence. Along with the ideology of Cartesian skepticism, through the thinking process, we are capable of the ability to doubt that which is surrounding them. This ability to think logically and doubt is what leads us to the confirmation of our existence.
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.
Descartes then states that he wishes to extend his knowledge through knowledge in his own self. He judges things that he once knew as fact to possibly now be doubtful and uncertain and that all his prior knowledge could have just been a work from a deceitful God. If then he wishes to learn from within himself and a deceitful God does in fact exist how can he affirm any knowledge within himself or even any knowledge he has affirmed through his meditations? If ideas that he once had now seemed uncertain then does that not mean all he knows can just be a work of a deceitful God, if of course a God does exist.
