Rene Descartes and David Hume both have had a profound effect on the philosophical world. Both these philosophers are associated explicitly with two separate schools of philosophy which are Rationalism and Empiricism. It is this division between Rationalism and Empiricism that allows for Descartes and Hume to present differing accounts of the mind and mentality.
Descartes is widely recognized as the father of modern philosophy, he is a rationalist, who considers knowledge of the metaphysical as existing separate from physical reality believing that truth cannot be acquired through the senses but through the intellect in the form of deductive reasoning. Rationalism does not involve the overcoming of religious thought. Descartes began with the basic epistemological premise of "the prior certainty of consciousness," which is the belief that the existence of an external world is not self-evident but needed to be proved by deduction from the contents of one's consciousness.
Descartes asserted that what is true knowledge is literally inborn with us. He had an attitude of doubt toward certain beliefs and that knowledge is limited. This attitude and methodology of thinking led him to doubt the existence of God and whether our own human existence was real or not. Descartes used the deductive method where he labeled all that was doubtful as false until nothing remained but that which was not doubtful as the truth. Descartes concluded that if one doubts, the doubting itself proves that one is thinking and therefore one exists.
By using the process of reason in geometry, Descartes found that the three angles of a triangle makes two right angles but that this same process of reasoning could not prove its presence. With this in mind, he went ...

Descartes on the other hand assumes that the "I think therefore I am" argument is the correct way to go about things. He assumes our thoughts are correct thoughts only when they appear to be correct. How do we know that we exist, because we think? How do we know for sure those two ideas correlate? He ignored the certainty of existence, proven by the contents of his mind, and instead opted for the belief that only his mind existed until he could prove otherwise. “How can I know I exist?”, or “How do I prove I exist?”
Maybe we should refer to an old classic: Star Trek the Next Generation. When the android, Lieutenant Data, asks if he is human, Descartes’ answer would be “yes” solely because he thinks. Yet Hume would probably disagree because he has no feelings therefore he cannot experience life. So the question remains; is Data human?
At the start of the meditation, Descartes begins by rejecting all his beliefs, so that he would not be deceived by any misconceptions from reaching the truth. Descartes acknowledges himself as, “a thing that thinks: that is, a thing that doubts, affirms, denies, understands a few things, is ignorant of many things” He is certain that that he thinks and exists because his knowledge and ideas are both ‘clear and distinct’. Descartes proposes a general rule, “that whatever one perceives very clearly and very distinctly is true” Descartes discovers, “that he can doubt what he clearly and distinctly perceives is true led to the realization that his first immediate priority should be to remove the doubt” because, “no organized body of knowledge is possible unless the doubt is removed” The best probable way to remove the doubt is prove that God exists, that he is not a deceiver and “will always guarantee that any clear and distinct ideas that enter our minds will be true.” Descartes must remove the threat of an invisible demon that inserts ideas and doubts into our minds to fool us , in order to rely on his ‘clear and distinct’ rule.
Before students can judge others ideologies they must understand the philosopher first. Rene Descartes, the father of modern western philosophy, was born in 1596 to French parents. Rene Descartes excelled in mathematics. By 1616 Descartes received his baccalaureate and became a licensed lawyer. In 1618 Descartes joined the army of Prince Maurice of Nassau. During his service Descartes never saw combat, but while in the service he was able to travel and explore the world. During his time in Germany Descartes began to inquire about life’s hardest questions regarding logic, reasoning, arithmetic, God and knowledge. By the early 1830’s Descartes continued his conquest of knowledge; he secluded himself from all temptations and began to write. Descartes
In the “Mediations of First Philosophy” Descartes tries to prove the existence of God in the third meditation. He does this by coming up with several premises that eventually add up to a solid argument. First, I will explain why Descartes ask the question, does god exist? And why does Descartes think he needs such and argument at this point in the text. Secondly, I will explain, in detail, the arguments that Descartes makes and how he comes to the conclusion that God does exist. Next, I will debate some of Descartes premises that make his argument an unsound one, including circular reasoning. Finally, I will see if his unsound argument has diminished and undermined his principal goals and the incorrigible foundation of knowledge.
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 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
There was one thing that Descartes knew for certain, he existed. If Descartes was able to think, then he existed, which comes from one of his most famous quotes, “I think; therefore I am.” He knew that since he existed, he could not have created himself, so something else had to have created his existence. He believed that one could go down the line and keep asking what caused that person to exist and so on until eventually ending with an infinite self-causing being, which is God. He used this notion of an existing God to prove his distinction of ideas.
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.
Descartes is a prime example of a rationalist. Descartes begins his Meditations on First Philosophy by doubting his senses in the first meditation. “From time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(Descartes: 12). In the second meditation, Descartes begins to rebuild the world he broke down in the first meditation by establishing cogito ergo sum with the aid of natural light. It is with this intuition that the cogito is established, from the cogito, intellect, from the intellect, knowledge; thus knowledge has been defined in this world that Descartes is constructing from scratch. Descartes uses the fact that he is a thinking thing to establish the existence of other things in the world with the cosmological and ontological arguments, as well as a meditation on truth and falsity. “So now I seem to be able to lay it down as a general rule that whatever I perceive very clearly and distinctly is true” (Descartes: 24). Descartes only utilizes his perceptions to establish ideas of the things t...
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’ attempts to extricate himself from his sceptical doubts of the meditations had a varying degree of success, his doubt of his own existence was well surmounted with the indubitable ‘cogito’ argument. The second of his doubts, that of the existence of God was not extricated as successfully with the unconvincing trademark argument and the out of date ontological argument. Descartes then went on to tackling his doubt regarding the existence of the external world, which was done well but was based on the shady proofs for the existence of God. Descartes may not have proven the existence of God or the existence of the external world however he did produce a new style of philosophy in which he attempted to base all of his epistemological knowledge (or beliefs) on a single indubitable premise, this style of philosophy now known as foundationalism has been and is still used by philosophers today at great credit to Descartes, Rene Descartes proved himself within this book to be the father of modern philosophy.
Unlike one of empiricism’s major tenets, Tabula Rasa, or blank slate, Descartes believed that the mind was not a blank slate, but actually came pre-loaded, if you will, with ideas, which are part of our rational nature and that our rational nature allows us to grasp . Descartes begins his journey deep within his own mind by claiming that all truths can be conceived by thinking about them. He calls his method cogito or pure reasoning. His famous words “I think, therefore I am,” describes the way that he thinks the mind is the true reality with the rest of reality being an extension. His example to prove thi...
Descartes was incorrect and made mistakes in his philosophical analysis concerning understanding the Soul and the foundation of knowledge. Yes, he coined the famous phrase, “I think therefore I am,” but the rest of his philosophical conclusions fail to be as solid (Meditation 4; 32). Descartes knew that if he has a mind and is thinking thoughts then he must be something that has the ability to think. While he did prove that he is a thinking thing that thinks (Meditation 3; 28), he was unable to formulate correct and true philosophical arguments and claims. For instance, his argument for faith that a non-deceiving God exists and allows us to clearly reason and perceive was a circular argument. Another issue with Descartes' philosophy is that he wanted to reconcile scientific and religious views, which is wrong since the two maintain completely different foundational beliefs and they should exist exclusively- without relation to the other. Thirdly, he believed that the mind was the Self and the Soul, failing to recognize that humans have bodies and the outside world exists, and through which we gain our knowledgeable. Lastly, Descartes argues that ideas are all innate while they actually are not- we gain knowledge through experience.
Descartes believes that the mind and body are separate of one another causing the problem to form in the transmission of information between the mind and the body. Hume does not conquer this task of mind and body one or separate. He is more concerned with the idea of self and how one is maintained over a period of time. He believes there is no such thing as self. That each moment we are a new being due to the fact that we are forever changing and nothing remains constant within ourselves. Yes, our DNA may be the same but that is not
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.
