Rene Descartes
Once upon a time we were told of the earth being the center of the universe. The sun, moon, and all planets even unknown were all revolving around our planet. We now look at that statement and wonder in amazement how our species could have pondered such a thought. Through advanced mathematical and persistently working to prove his theory, Rene Descartes transformed yet another one of these worldly assumptions and proved it all wrong.
Rene Descartes Method of Doubt was simply his mathematical method in discovering the unanswered questions about the universe. He wanted to prove every unknown question and be certain that he could prove his truths with knowledge given only by mathematical proof. "Common Sense", which Descartes refers to as natural reason, is the understanding of all humans with many given subjects. He feels that in some common sense areas, one should just be expected to know what all humans are assumed to know and therefore, does not need to be mathematically proven.
In the face of Rene Descartes extreme doubt, he found that he hoped to use skepticism to find complete certainty. When doubting something, Descartes would start by asking if it is rationally possible to doubt everything. When proceeding to do this, he will find if there is any undoubtedly truth. Instead of Descartes trying to examine every belief that he holds, he examines the origins of different types of beliefs. In doing this, he rejects any idea that could be mistaken, and will reject it right away.
The importance of Rene Descartes view of Philosophy is the mere fact that he was completely about proof. He needed proof to believe in something, and proof was found through a truth, which is gained in knowledge. His knowledge was thus gained mathematically. His importance was not only by proving ideas through mathematics, but proving the existence of God. He tried building a reliable foundation for knowledge with the idea of God. As Descartes states, "If God is all knowing, all good, and all powerful, he would not let us live in constant ignorance." He gives other individuals incentive to find the truth, even if they feel the basis of there finding a truth is impossible. Descartes uses methodic doubt as a form of ruling out all obstacles of ideas that could even remotely be false.
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 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 asserts knowledge is done through experimentation using a scientifc method to removing opinions, and come up with a solution to conflicts. In the Discourse on Method, Descartes describes his unique style of reasoning, and makes clear that his main goal for writing is to solve epistemology, or the theory of knowledge. Similar to Socrates, Descartes sensory perceptions cause a false belief in the world around us, he believes one needs to be thinking on the intelligible level, however Descartes provides a different method to achieving this goal.
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
René Descartes was the first philosopher to raise the question of how we can claim to know anything about the world with certainty. The idea is not that these doubts are probable, but that their possibility can never be entirely ruled out. If we can never be certain, how can we claim to know anything?
Montaigne and Descartes both made use of a philosophical method that focused on the use of doubt to make discoveries about themselves and the world around them. However, they doubted different things. Descartes doubted all his previous knowledge from his senses, while Montaigne doubted that there were any absolute certainties in knowledge. Although they both began their philosophical processes by doubting, Montaigne doubting a constant static self, and Descartes doubted that anything existed at all, Descartes was able to move past that doubt to find one indubitably certainty, “I think, therefore I am”.
Descartes explains that math is one of the only perfect things in the world. Math has a solid foundation, and there certainty in every question. Descartes has a huge influence in the Cartesian coordinate system, which “allows to take reference points in space in a set of numbers”. One reason why I reject Geocentrism is because of the Cartesian coordinate system. Scientists have used this to understand and plot Earth’s elliptical orbit in a mathematical sense. Descartes did not trust anyone he didn’t even trust himself. This caused him to fall in love with math and physics, because of the certainty and truth in the principles. In his Discourse, he explains, “For my notions had made me see that it is possible to reach understandings which are extremely useful for life, and that instead of the speculative philosophy which is taught in the schools, we can find a practical philosophy by which, through understanding the force and actions of fire, air, stars, heavens, and all the other bodies which surround us” (Part 6). Explaining how life is more than the mind and soul, Descartes provides society with the beginning of the laws of nature as well as an introduction of planetary motion. Using his newly acquired knowledge he shows us that
After all of Descartes' study and contemplation of math and science, he decided to find a single principle without doubt on which to build knowledge. His purpose in life became the development of a metaphysical theory that would prove the mathematical truth he had found. His analytical system of doubt led him to doubt everything in the world. He finally reached the conclusion that everything can be doubted except for one thing, his own existence. Even this was called into doubt and found true. Descartes rationalized that by doubting his own existence, he was thinking. If he was thinking, then he must exist. Then he contemplated whether he was awake or asleep. If he was asleep, then he was dreaming that he was thinking and therefore not existing. He decided that one could use sense perception to realize if one was awake of asleep. Finally he concluded, "I think, therefore I am." This became the basis for his entire system of beliefs. Descartes' argument for existence was called "cogito ergo sum." All of Descartes philosophical arguments were made by analytical means. He deduced the conclusion.
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.
In conclusion, Descartes efforts in changing the traditional way of learning where not so successful, but because he had such unique ways of thinking he was considered the father of modern philosophy. I think because of his confusing thoughts of doubting everything even thing that may be 100% correct to still doubt it and then saying to forget get all about the doubting to prove that (i.e. God) something is really. I personally do not think this is a logical when of learning.
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 argued that this inscription can sometimes be faulty and therefore what one accepts as being knowledge may be questioned. In Meditations Descartes tried to ensure that his tableaux contained certain truths, he therefore used doubt, as a sieve, to achieve this. Scepticism played a large role in Descartes' quest for certain knowledge. He constantly questioned accepted truths, this meant that he never accepted facts based purely on assumptions. For Descartes a conclusion was not valid unless it was supported by evidence.
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...
