Epistemology can be defined as the theory of the nature and knowledge in reference to its value. This means the study of facts on knowledge. Epistemologists, try to evaluate the commonsense idea that we have knowledge and that we are rationally justified in the beliefs we have. Descartes way of thinking is through Method of Doubt. Descartes attempted to use the fundamentals of knowledge and the method of doubt he used during his time of mediation became an essential part of epistemology.
Descartes meditations can be described as doubt. He tries to find something that will last and stay stable. By him doubting all known facts, he shows purpose and asks the question if anything is really and truly certain. Descartes looked at history and discovered that facts that were thought to be completely true actually were later found to be wrong. Descartes found that facts can stand alone in the test of doubt and these facts can be used as fundamentals of knowledge.
There is a close connection between knowing something to be true and being certain of it. Descartes, as well as many other philosophers, have maintained the belief that knowledge and certainty go together. This leads to the question, if everything is certain, then a person cannot have knowledge at all. This is the reason Descartes attempted to find the fundamentals of knowledge by doubting existing facts.
People’s knowledge can be usually connected in three meanings. Knowing can be used in the context of having skill, having awareness or object knowledge, and prepositional knowledge. This is the point where Descartes begins to doubt the things that people seem to know as factual knowledge but not always certain in what they know. An example of this idea is, someone could be aske...

People would say that Descartes was a skeptic because he doubted all knowledge. He was actually not a skeptic. He did not doubt knowledge to falsify a truth. He doubted knowledge that was indubitably correct and that could serve as fundamental knowledge. Through Descartes method, Epistemologists and Descartes created a new way in philosophy.
Descartes doubted common sense that everyone took as fact. His thinking led to a useful use in epistemology. Now people would say that there is no other life in the universe. With this statement you can either deem it as true or false. There is an attempt to find certain that there is intelligent life in the universe. Descartes attempt to eliminate things that are thought to be fact to things that are certain.
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.
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.
In his book Meditations on First Philosophy, Descartes tries to accomplish several subject concerns. Firstly, Descartes attempts to accomplish the use of methodological doubt to rid himself of all beliefs that could be false. Then, he arrives at particular beliefs that could not possibly be false. Next, he discovers a criterion of knowledge. Also, he proves that the mind is distinct from the body and also the existence of God.
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. 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
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,
Not only did Descartes set aside all of his previous knowledge, but he also set aside all knowledge he had gained, and that he continued to gain from his five senses. He would not believe what his eyes saw, or what his hand felt, because he could not yet determine his senses as giving him knowledge that could be turned into certainties. He did not have any reason to believe that he could rely on his senses. Descartes doubting of his senses also caused him to reject any knowledge that he had gained through life experience. Most of the knowl...
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.
Understanding Descartes’ philosophy begins with understanding his method of doubt. Think about it like this. Almost everything you believe to be true comes from the senses or through the senses. However, the senses are sometimes deceptive. Since the senses are not completely trustworthy, it is irrational to place complete trust in them. However it is no small leap of faith to presume that everything our senses tells us is false. In fact, it seems almost preposterous to say such a thing. But as Descartes points out, we have dreams regularly and in these dreams everything we experience is a figment of our imagination, or at least not real in the physical sense. So, at least according to Descartes, it is reasonable to doubt everything our senses tell us, for the time being. Now, using similar logic, we can say that everything we have learned from physics, astronomy, medicine, and other such fields are all doubtful. Descartes even believed we could say that such simple, logical statements as 2+3 = 5 or a square has 4 sides could be conceived to be false. “Since I judge that others sometimes make mistakes in matters that they believe they know most perfectly, may I not, in like fashion, be deceived every time I add two and three or count the sides of a square…'; We are now at the point where we are doubting everything – the world around us, that we have a body, and anything else that we could possibly...
The question now is how are we to doubt everything? Descartes claims that we are fooled by our minds, meaning we do not really know what is false or not. For instance, one a hot day you look at a the ground at a distance and think you see water, but in reality the heat rising from the ground which from a certain angle looks like water but then when you get closer you see the ground not water. In addition, Descartes que...
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.
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.
“The basic strategy of Descartes’ method of doubt is to defeat scepticism on its own ground. Begin by doubting the truth of everything—not only the evidence of the senses and the more extravagant cultural presuppositions, but even the fundamental process of reasoning itself.”( Kemerling).
Descartes defines knowledge as doubt and uncertainty. He describes that our main source of knowledge is our sense perception.
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...
