Questions on Rene Descartes (1596-1650 CE)
(PHI 102)
Dr. Foster
1. Explain the philosophical mission undertaken by Descartes in his Meditations.
Descartes’s mission in his Meditations was to use the method of doubt in order to rid his mind of all beliefs that could be proved false. This provided him with the opportunity to arrive at some beliefs that could be proved ultimately right. In other words he wanted to find all beliefs that could not be false at all.
2. Would you describe Descartes’ epistemology as a priori or a posteriori? Explain your answer.
I would describe Descartes’ epistemology as a priori. Descartes uses the method of doubt in order to prove ideas and beliefs to be ultimately true or false. He does not use his experiences

As in the definition of 2+2=4. Descartes spent what seemed like such a massive amount of time doubting beliefs and ideas that math seemed like the only thing that could not be doubted.
4. What role does extreme doubt play in Descartes’ philosophical mission?
Descartes use the method of doubt in order to prove beliefs and ideas to be true or false. This allowed him to make skeptical hypotheses that even called doubt upon his own knowledge. Which ultimately allowed him to come up with the conclusions found in his Meditations.
5. Delineate the epistemological criteria that Descartes relies upon to determine which ideas are not legitimately subject to doubt.
Descartes grouped certain ideas and beliefs into categories in order to use his method of doubt effectively. He uses the imagination, senses, and reason in order to make sense of the beliefs derived from the specific categories listed. Like I said before he then provides himself with skeptical hypotheses that even bring doubt into his own beliefs. So each of these categories go through this skeptical hypothesis and those that pass the first go through a second and so on, but those that fail can be proved false. This allows him to find beliefs and ideas that cannot be proved false at all such as how
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.
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.
Descartes knows that with the mathematical theory everything in the mind is self-evident. However, the more outside of the mind something is the greater the challenge it is to know something is self-evident then when it is visibly seen, and out of the mind. This is what he is explaining when he says “I readily discover that there is nothing more easily or clearly apprehended than my own mind” (Descartes 83). This stems his idea to create the mathematical superstructure. To think about something quantifiably is think of something
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
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.
Descartes’ theory of systematic doubt centered on his belief that individuals cannot trust their perceptions of the external world because sensory stimuli do not necessarily reflect true depictions of the world. Throughout his life, Descartes assumed information being received through his senses to be accurate representations of the external world until he realized that the senses as a source for information can occasionally mislead both himself and all other people. With this knowledge in mind, Descartes knew that an absolute confidence in sensory perception could deceive individuals about the external world and lead to a challenging of beliefs. As an example of this, Descartes considered that, as he wrote this meditation on systematic doubt,
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.
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 Meditations on First Philosophy, it is the self-imposed task of Descartes to cast doubt upon all which he knows in order to build a solid foundation of knowledge out of irrefutable truths. Borrowing an idea from Archimedes, that with one firm and immovable point the earth could be moved, Descartes sought one immovable truth. Descartes' immovable truth, a truth on which he would lay down his foundation of knowledge and define all that which he knows, was the simple line "Cogito ergo sum": I think, therefore I am. This allowed for his existence.
While on his journey to reveal the absolute truths and debunk anything that could be considered doubtful, Descartes’ experiences using this form of skepticism has allowed him to
Descartes’ method is ultimately about finding the truth within yourself. He says that there are two types of people that would not benefit from his method: those who think they know more than they do and who lack the patience for such careful work, and those who are modest enough to think that they are more capable of finding out the truth if they follow a teacher. Descartes also creates a three to four maxim moral code to guide his behavior while he experiences his period...
Descartes’ first two Meditations are arguably the most widely known philosophical works. Because of this, one can make the error of assuming that Descartes’ method of doubt is self-evident and that its philosophical implications are relatively minor. However, to assume this would be a grave mistake. In this paper, I hope to spread light on exactly what Descartes’ method of doubt is, and how, though it furnishes challenges for the acceptance of the reality of the external world, it nonetheless does not lead to external world skepticism.
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.
Firstly, Descartes made the mistake of supporting a conclusion with premises that can only be true if the conclusion was a premise for the other premises that were supporting it. To clarify, Descartes basically stated that the clarity of his reasoning and perceptions are only possible through the existence of a non-deceiving God and that the non-deceiving God can only be proved through the clear reasoning and perceptions that the non-deceiving God bestowed upon him (51, 52). This is clearly a...
Rene Descartes, a 17th century French philosopher believed that the origin of knowledge comes from within the mind, a single indisputable fact to build on that can be gained through individual reflection. His Discourse on Method (1637) and Meditations (1641) contain his important philosophical theories. Intending to extend mathematical method to all areas of human knowledge, Descartes discarded the authoritarian systems of the scholastic philosophers and began with universal doubt. Only one thing cannot be doubted: doubt itself. Therefore, the doubter must exist. This is the kernel of his famous assertion Cogito, ergo sum (I am thinking, therefore I am existing). From this certainty Descartes expanded knowledge, step by step, to admit the existence of God (as the first cause) and the reality of the physical world, which he held to be mechanistic and entirely divorced from the mind; the only connection between the two is the intervention of God.
