Paper 1 Descartes brings up an interesting idea and methodology, and specifically the idea that we should take everything that we believe is true, and be skeptical of it, thus in doing so we find one undeniable truth and build upon the truth to reinforce our other beliefs. During the process of skepticism, if any doubt arises to the mind of whatever you believe in, you deem the entire belief as false. When finding the foundational truth, it must be undeniably true. This method of finding an undeniable truth is necessary, because this would allow all other philosophers to be on the same page and able to agree, thus being able to build knowledge around one central and undeniable truth to establish a belief.

Descartes states that “…even though the senses do sometimes deceive us when it is a question of very small and distant things, still there are many other matters concerning which one simply cannot doubt, even though they are derived from the very same senses…” (Descartes 60). He believes that the senses can deceive you, and they cannot be trusted. For example, Descartes states that our senses are deceived when we dream. Dreams are able to deceive you, for instance, you are having a dream that you are flying over the Atlantic Ocean. Your eyes are telling you that you see blue whales swimming gracefully in the beautiful blue ocean, but in reality, you are sleeping in your cramped room in Chicago hoping you don’t have to shovel your car out of snow the following day. Your dreams lead you to believe that you are sensing something other than reality. How do we know we are not dreaming right now? It is impossible to entirely rule out the possibility. Once we have deemed that one sense does not work, we can deem all other senses to be untrusted as Descartes believes that these senses are encapsulated. We can also relate to his foundational methodology, where once we have skepticism, we can deem it as false and untrue. If we are unable to use senses as a means of finding a foundational truth, then can we possibly use math and …show more content…
You have to be able to distinguish between what false and true is. Because if we were to mistakenly confuse between truth and false, our system for finding truths would be impossible. To find this truth, I believe following Descartes method of using an undeniable truth as a foundation and building upon it. Thus, rejecting all current beliefs and deeming them as untrue is the only way to building a solid foundation. Once you reject all current beliefs, you find your solid foundation of truth, and build a skyscraper of knowledge upon the foundation, which in theory, would be an undeniably true set of knowledge. But there are drawbacks to this method. Going through all the information and trying to prove everything based off of one undeniable truth would take too long, thus being

Physically, humans consist of muscle, bones, blood, cells, but how do we really classify what makes a human a human? What if someday a scientific finding occurs and we learn that we can move a person's brain to another person's body, or into an robot. Are they still the same person or even a person? Opposite sides would say no, because the flesh is not the same or even there at all, but those sides are forgetting all the memories that the brain possess.If a person is aware of their conscious and unconscious minds, they are human.
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.
René Descartes was a French philosopher who refused to believe that true knowledge was obtainable through the means of sense perception. Descartes believed that the senses; as we know them, could be manipulated and twisted into providing false understanding of the external world. In the search for the truth amongst what we perceive in life, Descartes is justified in his claims that our senses cannot be trusted. Only by questioning all that is known as human beings, can one find the absolute truth in life. Through the use of two different thought experiments, Descartes uses reasoning to questions what we perceive as reality and truth.
The next stage in the system, as outlined in the Meditations, seeks to establish that God exists. In his writings, Descartes made use of three principal arguments. The first (at least in the order of presentation in the Meditations) is a causal argument. While its fullest statement is in Meditation III, it is also found in the Discourse (Part IV) and in the Principles (Part I §§ 17–18). The argument begins by examining the thoughts contained in the mind, distinguishing between the formal reality of an idea and its objective reality. The formal reality of any thing is just its actual existence and the degree of its perfection; the formal reality of an idea is thus its actual existence and degree of perfection as a mode of mind. The objective reality of an idea is the degree of perfection it has, considered now with respect to its content. (This conception extends naturally to the formal and objective reality of a painting, a description or any other representation.) In this connection, Descartes recognized three fundamental degrees of perfection connected with the capacity a thing has for independent existence, a hierarchy implicit in the argument of Meditation III and made explicit in the Third Replies (in response to Hobbes). The highest degree is that of an infinite substance (God), which depends on nothing; the next degree is that of a finite substance (an individual body or mind), which depends on God alone; the lowest is that of a mode (a property of a substance), which depends on the substance for its existence.
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.
It is easy for us to believe that what we experience with our senses is true, including in our dreams, but according to Descartes, we should look beyond our senses and use reasoning to determine what is certain. Descartes’ question, “For how do we now that the thoughts that arise in us while we are dreaming are more false than others, since they are often no less vivid and explicit?” (34), is asked so that we will acknowledge that our senses can easily mislead us. This should then cause us to use reasoning to differentiate between truth and illusion, and both authors agree that reasoning should be the guide to true knowledge. Though he believes in the attainability of certain knowledge through using reasoning, Descartes argues that there are only a few things about which we can be certain. Descartes’s philosophy “Cogito, Ergo Sum,” which means I think, therefore I am proves this. He believes that because our mind acknowledges that we can think and have doubts, we can be sure of our existence; if we stopped th...
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.
Descartes was incorrect and made mistakes in his philosophical analysis concerning understanding the Soul and the foundation of knowledge. Yes, he coined the famous phrase, “I think therefore I am,” but the rest of his philosophical conclusions fail to be as solid (Meditation 4; 32). Descartes knew that if he has a mind and is thinking thoughts then he must be something that has the ability to think. While he did prove that he is a thinking thing that thinks (Meditation 3; 28), he was unable to formulate correct and true philosophical arguments and claims. For instance, his argument for faith that a non-deceiving God exists and allows us to clearly reason and perceive was a circular argument. Another issue with Descartes' philosophy is that he wanted to reconcile scientific and religious views, which is wrong since the two maintain completely different foundational beliefs and they should exist exclusively- without relation to the other. Thirdly, he believed that the mind was the Self and the Soul, failing to recognize that humans have bodies and the outside world exists, and through which we gain our knowledgeable. Lastly, Descartes argues that ideas are all innate while they actually are not- we gain knowledge through experience.
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
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 is clearing away all knowledge that can be called into doubt. By doing this he hopes to create something real and lasting in the sciences, a foundation to build on. This indisputable fact will become the starting point or origin of all other true knowledge he can build upon it. He starts the first argument by attacking the very beginning of knowledge, human senses. Descartes states, "Surely whatever I had admitte...
