Cogito Ergo Sum

Cogito ergo sum, a phrase that is said to be the fundamental element of western philosophy and what was the centerpiece of Rene Descartes’ epistemology. It is a simple statement but one that sets the standard for a principle upon which all knowledge is based. Many sources assess René Descartes to be the father of modern philosophy. In his lifetime he had made many noteworthy contributions to mathematics and physics. And there are of course his philosophical contributions in the theory of knowledge. His most famous work was his epistemological project, Meditations on First Philosophy which after his was completed Descartes’ work was passed on to other philosophers for their comments and criticisms. Descartes responded with detailed replies that provide a rich source of further information about the original work. He published the first edition of the Meditations together with six sets of objections and replies in 1621 and added a seventh set with the second edition a year later in 1642. René Descartes’ did not agree and was able to disprove the traditional Scholastic-Aristotelian philosophy most common during his time. He also developed and promoted a new philosophy, what is now called western philosophy. Both these points justify his title of being the “Father of Modern Philosophy". His foundational break with Scholastic philosophy involved two facts; first, because of the reliance on sensation as the source for all knowledge Descartes thought that the Scholastics’ method was likely to lead to doubt. Second, he wanted to replace final causal model of scientific explanation with the more modern, mechanistic model which would involve mathematics and physics. The first issue Descartes had with Aristotelian philosophy was that it wasn't concrete and based on feelings so Descartes attempted to address this issue with his method of doubt. His basic strategy was to consider false any belief that could lead

    Rene Descartes lived from 1596 to 1650. He was born in France, and went to a Jesuit primary school. He earned a law degree, but later on he began focusing on math and logic in the world. During the early 17th century, his ideas deviated more and more from previous philosophers. Because of this, he became known as “The Father of Modern Philosophy.” While some of his ideas weren’t completely original, his way of getting to them was. He believed in totally ignoring everything previous philosophers had done, and starting new, as if their work had never happened. He did not even trust his own emotions. He also believed that consciousness was the only truth in the world, leading to his most famous statement, “I think; therefore I am.” He also published several books, and despite his late entrance in the subject, and early death, he is still one of the most…

    Rene Descartes was a French mathematician, scientist and philosopher. He’s known as the founder of modern philosophy. He applied the idea of the clockwork mechanism to the human body. During the 17th century Descartes came up with the idea of dualism. This idea was described as, the mind and body being two separate realms that interact to form the human experience. He employed a method called methodological skepticism, meaning, he rejected any ideas that could be doubted. He came to the conclusion that he can be certain that he exists because he thinks. Descartes is, also, known for the Wax Argument. He claimed if he looked at a piece of wax he could describe it using his senses- shape, texture, color, smell. If he moved the wax towards a flame the wax would change characteristics (A History of Modern Psychology, 2014).…

    Rene Descartes, a French philosopher attempted to craft groundwork to establish further scientific developments. He rationed that once one knows the foundations of a belief and one builds upon that, much of what one believes can be doubted. He held that through using math’s methods, he could apply these same methodologies to other ideas. Descartes believed that nothing can be perceived more easily and evidently than his own mind. By applying his theory, that he knew nothing for certain but was aware of his own thought, he started to combat already instituted ideas and conjured up the existence of…

    Both were men of science, and applied science as they understood it to their philosophies. Bacon believed in inductive reasoning which would be the basis for the scientific method. Determining truth was a matter of performing experiments, noting the conclusion, and vigorously testing the results. Descartes on the other hand was a believer of deductive reasoning, reasoning that one could infer truth from building upon self-evident statements and mathematical clarity. Descartes contributed greatly to western thinking largely due to his insistence on skepticism in science, which combined with Bacon’s inductive reasoning represents the commonly accepted method used by scientists to this…

    Descartes’ method offers definitive conclusions on certain topics, (his existence, the existence of God)but his reasoning is not without error. He uses three arguments to prove existence (His and God’s) that attempt to solidify his conclusions. For his method to function seamlessly, Descartes needs to be consistent in his use of the method, that is, he must continue to doubt and challenge thoughts that originate in his own mind. He is unable to achieve this ideal state of mind, however, and his proofs are shown to be faulty.…

    In Meditation I, Descartes reflects on his past beliefs and realizes how so much that he once believed to be true was actually false. To separate what is truth from fiction; Descartes decided to completely reject anything which he can doubt at all. He wrote, “If I am able to find in each some reason to doubt, this will suffice to justify my rejecting the whole” (Descartes 4). The belief that inspired this method was that genuine truth was clear and distinct and that any doubt whatsoever could not provide absolute certainty. In essence, if any component of something was in the very least questionable, then any conclusion drawn from it would be at the most questionable. This method led Descartes to doubt practically everything he once believed, especially knowledge attained through the senses. He wrote, “All that up to the present time I have accepted as most true and…

    Medieval techniques for ascertaining truth differed greatly from scientific views, mostly in part to what was taught in the Middle Ages by the church. Medieval traditional views put more faith in made up truths to fit their own religious dogmas or referring to long trusted authorities. Widely held by the populace in medieval times their views did come from some scientific origin in the form of a philosopher named Aristotle. Aristotle’s works merged with Christian views helped formed what we know today as medieval traditional views. During the 15th and 16th centuries however new views started to undermine this way of thinking. Neoplatonism based on the ideas of Plato combined with Hermetic doctrine provided especially powerful alternatives to Aristotelian thought. Or (helped form a bridge to the scientific revolution).…

    The aim of Descartes’ first meditation is to first rid the mind of opinion and to only believe what is true. The second goal of his is to begin to put sciences on a firm foundation. He plans on achieving these goals by using a methodological doubt process in which he will see if he can discover a basis or corrosive agent that can bring all his beliefs into doubt. He believes that once a belief can be doubted, all…
