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.
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 major concern is what we can know to be actually real. This concern starts from a dream he has, in his dream he thinks he is actually awake, so when Descartes does wake up he begins to question reality. On page 75 and 76 he says “ But I had the persuasion that there was absolutely nothing in the world, that there was no sky and no earth, neither minds nor bodies; I was not, therefore, at the same time, persuaded that I did not exists? To solve this he tosses out all emotions and reasons to try to figure out what actually exists. He starts himself on this hyperbolic doubt, increasing levels of doubt, meaning he continues to doubt himself until what he is left with is Cogito Ergo Sum. . Cogito Ergo Sum is being aware of disembodied thinking. He uses this as proof of his existence, because having thought, whether wrong or right, is proof that one does exist.
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.
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”.
...s" and the "Father of Modern Rationalism." His system of deductive reasoning has been adapted to almost every field of study. His major contributions to the field of math were the Cartesian coordinate system, the exponent, and the development of analytical geometry. His major contributions to the field of philosophy were the "cogito," the system of doubt, and the classical ontological proof of God. Descartes has influenced thought throughout the ages. His works, especially Meditations, Geometry, and his Discourse on Method have become classics. Rene Descartes, although he died at the premature age of 54, was a great mathematician and philosopher well disciplined in all genres. He will always be best remembered for proving his own existence by the statement, "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
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.
The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
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.
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.
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.
