Descartes aimed to rebuild knowledge and philosophy. The first and primary principle of his methodology was “never accept anything as true that I did not plainly know to be such (Discourse 19).” He believed that a large number of opinions, beliefs, and knowledge of human beings were false, but he could not justify which ones were true or which ones were false because all of knowledge are interacted and correlated with each other. Why are not existed beliefs, opinion, or knowledge true? All of those are got by and through sensations which deceive human beings sometimes. Descartes introduces the dreaming doubt arguments to prove that people’s sensations can be false.
People often have very similar sensations both in dream and in reality. For example, I am writing course paper about Descartes’ philosophy in front of my computer. How do I know I do not finish this action in my dream? I mean I am dreaming right now in which I am writing course paper about Descartes’s philosophy in front of my computer. I cannot distinguish whether I am sleeping or awake. Consequently, all of my perceptions and sensations are false. Another argument aiming to prove that all of our knowledge can be doubt is the Evil Demon Doubt. He starts his argument by supposing that there is a God who creates me and can do anything. I am like a puppet who is manipulated by the God. The God makes me believe that the sum of all the angles of a triangle is 180 degrees. He has the power to create and control use, so he also can deceive us. The sum of three angles of a triangle may be not 180 degrees, but the God deceives that it is that number. Descartes ascertains that even the fundamental part of knowledge may be false. However, people firmly believe that the God is supremely good, so he cannot deceive us. Here, Descartes introduces the evil genius who has the same power as the God, but the former is a not good one and he deceives all of our perceptions …show more content…
The process of thinking whether there is not anything else proves that he exist. If he does not exist, why can he provide this question? He may be deceived by some evil genius that he mentioned above, but how these clever deceivers deceive nothing if nothing exists? Descartes concludes that he exists. How long can he exist? One will exist as long as he can think. In other words, he ascertains that he is a thinking thing. The knowledge of a thinking thing is true and indubitable. He discovers the truth and his knowledge of science and philosophy depends upon the truth. One is able to doubt the square of ten is one hundred if the fact that one plus one equal to two is doubtful. Likewise, all of knowledge will be true if they are built upon the Cogito argument. Moreover, he shows that mind is more dependable than senses by using the example of wax.
Descartes points out that the senses are not reliable by using the dreaming out argument and the evil demon argument. People attain their knowledge through seeing, hearing, smelling, and imagining, so all existed beliefs should be open to doubt. Is there anything that is certain? Descartes discovers that I think therefore I am and he uses this truth as the foundation to build a new system of knowledge and
