Essay about Descartes’ Cogito

In the First Meditation, Descartes gives us the Evil Demon Hypothesis which serves to give him reason to doubt the existence of everything he perceives and believes. He describes a ‘malicious demon of the utmost power and cunning’ that has the sole purpose of deceiving Descartes (Descartes, 2010: 17). I will argue that his hypothesis has proven to be a strong one because only the cogito provides a way for us to frustrate or trick the evil demon.

Descartes’s mission in the meditations was to doubt everything and that what remained from his doubting could be considered the truth. This lead Descartes to argue for the existence of God. For the purpose of this paper, I will first discuss Descartes’s argument for the existence of God. I will then take issue with Descartes’s argument first with his view on formal reality and varying levels of reality, then with his argument that only God can cause the idea of God. I will then conclude with

The cogito, “I think” is Descartes’ first certainty and his first step into knowledge. Descartes argues that there is one thing that he is most certain of and even the evil demon can manipulate and make him doubt. He cannot doubt that he thinks because even doubting of a form of thinking and that means that he will be thinking. Even if the demon made him doubt that he is thinking, he would be confident that he is thinking that the demon is making him doubt his thinking. He cannot also doubt that he exists and if he were to doubt of his existence, he would prove that he exists because of his thoughts, and thus his thinking means he exists and hence if he exists then he must be thinking of his existence. Therefore, Descartes extends his certainty

The argument, as Descartes presented, does not give a valid reason for the existence of the body or anything else in the physical world, so we cannot accept that bodies exist. Neither does the cogito account for the existence of other minds as that would entail knowledge of the physical world where other things exist. The cogito concept does however; give a valid argument for the existence of the mind or a thinking thing that exists independently of the body. In his novel Think, Blackburn explains the cogito concept as a means of justifying the core of one’s existence as thinking, we accept that thought exists not a ‘self’ (Blackburn, 2001:20). I agree with Blackburn because his [Descartes’] concept serves well to prove that we exist as thinking things and even if we were to discard any a priori or a posteriori knowledge, we can still endorse the cogito.

First lets look at its strengths. In my opinion, the primary strength of Descartes argument lies in the fact that he claims the certainty of his own existence only. He utilizes a first person point of view throughout the meditations in order to exemplify the fact that he is not trying to prove the existence of others. This view of thinking is easily applicable to our own lives. This form of thought allowed Descartes to further his foundationalism whilst still maintaining his skepticism. Descartes acknowledged that this argument on its own proved very little and was open to questioning; yet it still provided a backdrop for the rest of his argument. Yet the Cogito is still not beyond all doubt. Just because Descartes has proven that thoughts exist does not necessarily mean that he exists. we could argue that merely thinking does not guarantee that ‘I’ exist, and therefore the cogito is not beyond all doubt. Descartes reject common definitions such as man, instead referring to simply “a thing.” Descartes concludes his

At the beginning of Meditation three, Descartes has made substantial progress towards defeating skepticism. Using his methods of Doubt and Analysis he has systematically examined all his beliefs and set aside those which he could call into doubt until he reached three beliefs which he could not possibly doubt. First, that the evil genius seeking to deceive him could not deceive him into thinking that he did not exist when in fact he did exist. Second, that his essence is to be a thinking thing. Third, the essence of matter is to be flexible, changeable and extended.

As with almost all of Descartes inquiries the roots of his second argument for the existence of God begin with his desire to build a foundation of knowledge that he can clearly and distinctly perceive. At the beginning of the third meditation Descartes once again recollects the things that he knows with certainty. The problem arises when he attempts to clearly and distinctly understand truths of arithmetic and geometry. Descartes has enough evidence to believe these things, but one major doubt is still present; the possibility of God being a deceiver. Descartes worry is that all the knowledge that he possesses through intuition could potentially be false if God merely chooses to deceive him. So in order to have a clear and distinct perception of arithmetic truths (and other such intuitive truths) Descartes delves into the question of God’s existence (and whether this God could be a deceiver or not).

Reneì Descartes’ treatise on dualism, his Meditations on First Philosophy, is a seminal work in Western intellectual history, outlining his theory of the mind and its relation to the rest of the world. The main argument running through the Meditations leads from his universal methodic doubt through his famous cogito, to proofs of dualism, God, and the world. The Cartesian dualism is one of the most influential ideas to come out of the work; the style of the Meditations, however, is one of personal rumination, following what appears to be Descartes’ stream of consciousness , and it allows for mild tangential discussions. Hence alongside his more famous argument for dualism,

In this paper, I offer a reconstruction of Descartes argument for God’s existence in the Third Meditation. Descartes tries to prove the existence of God with an argument that proceeds from the clear and distinct idea of an infinite being to the existence of himself. He believes that his clear and distinct idea of an infinite being with infinite “objective reality” leads to the occurrence of the “Special Causal Principle”. I will start by discussing and analyzing Descartes clear and distinct idea of an infinite being and how it the classification of ideas and the difference between formal and objective reality Special Causal Principle. Finally, I will examine the reasons Descartes offers for his belief in Gods existence and I will indicate the drawbacks within the proof. It will be concluded that Descartes arguments are inadequate and don’t clearly prove the existence of God.

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 the first meditation, "Concerning those things that can be called into doubt", Descartes main goal is to distinguish what it is he can take to be true, and what supposed truths hold even the smallest degree of doubt. When he reviews all of his opinions he concludes "eventually [he] is forced to admit that there is nothing among the things [he]believed to be true which it is not permissable to doubt--and not out of frivolity or lack of forethought, but for valid and considered reasons. Thus [he] must be no less careful to withhold assent henceforth even from these beliefs then [he] would from those that are patently false, if [he wishes] to find anything certain."(Pg62) At the beginning of Descartes' meditations, he finds that there is really no concrete pillars of knowledge to base the foundations of his supposed

Descartes uses the Evil Demon hypothesis to prove that all one knows for sure is that they exist. To call reality into doubt, Descartes supposes the existence of an all powerful, evil deceiver, a supposition which he asserts he cannot know to be false. Descartes supposes that it is conceivable that this deceiver has tricked him in every moment of what he perceived to be life, such that, every feeling and every experience Descartes ever had was merely a sequence synthesized by the deceiver. This being could powerful to not only manipulate our senses, but to cast doubt over other things such as mathematics.Thus, he renders himself into a state of complete uncertainty and denial of all known existence, since he cannot be certain that this deceiver does not exist. Any understanding or knowledge that there is could simply be an illusion or false input. Later, Descartes refutes the existence of such a being. Instead, he puts forth the assumption of a merciful God. His

In the meditations, Descartes evaluates whether or not everything we know is a reality or a dream. Descartes claims that we can only be sure that our beliefs are true when we clearly and distinctively perceive them to be true. As the reader analyzes the third meditation, Descartes has confirmed that some of his beliefs are in fact true. The first is that Descartes himself exists. This is expressed in what has now become a popular quote known as the “Cogito” which says, “I think therefore I am. His second conclusion is that God exist and that he is not a deceiver. Descartes then presents his arguments to prove the existence of God. He argues that by nature humans are imperfect beings. Furthermore, humankind could not possibly be able to comprehend perfection or infinite things on their own. He writes, “By the name of God I understand a substance that is infinite, independent, all-knowing, all powerful, and which myself and everything else…have been created.”(16) Descartes uses this description of God to display the distinction between God and man.

Rene Descartes Meditations is known to be one of his most famous works, it has also shown to be very important in Philosophical Epistemology. Within the meditation’s he provides many arguments that remove pre-existing notions, and bring it to the root of its foundation which Descartes, then will come up with his indubitable foundation of knowledge to defeat any doubt and to prove God is real. Descartes was a “foundationalist”, by introducing a new way of knowledge and with clearing up how people thought about things prior. Descartes took knowledge to its very foundations, and from there he can build up from it. In this essay, I will be discussing Descartes, and analyzing his first two meditations and arguing that he does indeed succeed in his argument.

During Meditations 2, Descartes establishes a version of his famous ‘cogito ergo sum’. He establishes that despite the fact that we may not know the world around us as well as we think we do, we can know the mind better and the trusting the mind can lead him to the seemingly justified conclusion that he exists.
