Descartes Doubt

In Descartes’ First Meditation, Descartes’ overall intention is to present the idea that our perceptions and sensations are flawed and should not be trusted entirely. His purpose is to create the greatest possible doubt of our senses. To convey this thought, Descartes has three main arguments in the First Meditation: The dream argument, the deceiving God argument, and the evil demon “or evil genius”. Descartes’ dream argument argues that there is no definite transition from a dream to reality, and since dreams are so close to reality, one can never really determine whether they are dreaming

By the first premise Descartes refers to an activity that the body does not participate in. For instance, perception and walking are two activities which either directly requires the body (walking) or relies upon the body (perception). The activity of thinking can be done without a body. You can clearly and distinctly imagine yourself without a body, but you cannot imagine not thinking. Premise 2 indicates this distinction even more. Since the activity of thinking is separate from the body then this activity does not fall into doubt. Anything the body senses or is part of the body can be doubted because the mind’s eye would only perceive the image the body creates which has previously be shown to be dubious. A possible objection is that Descartes is pointing to another representation which the body has created. For instance, the body has created the image of thinking which the mind’s eye views. In addition, could we not be dreaming and thus deceived that we are thinking or could there be a demon deceiving

Descartes’ method of radical doubt focuses upon finding the truth about certain things from a philosophical perspective in order to truly lay down a foundation for ideas that have the slightest notion of doubt attached to them. He believed that there was “no greater task to perform in philosophy, than assiduously to seek out, once and for all, the best of all these arguments and to lay them out so precisely and plainly that henceforth all will take them to be true demonstrations” (Meditations, 36). The two key concepts that Descartes proves using the method of doubt are that the “human soul does not die with the body, and that God exists” as mentioned in his Letter of Dedication, since there are many that don’t believe the mentioned concepts because of the fact that they have not been proven or demonstrated. (Meditations, 35). In order to prove the above, he lays out six Meditations, each focusing on a different theme that leads us “to the knowledge of our mind and of God, so that of all things that can be known by the human mind, these latter are the most certain and the most evident” (Meditations, 40).

As a thinking entity, Descartes is a consciousness mind aware of the potential to engage in various modes of existence. To the numerous operations of “thought” he includes doubting, understanding, affirming, denying, willing, refusing, imagining, and sensing. As varied and manifold as these operations appear, they are but expressions of two principal types of conscious activity, to which Descartes eventually traces the nature of error. Thinking and reasoning, together with all belief in general, depend upon the operation of the twin faculties “knowing” and “choosing,” or the free will. Garrett Thompson writes:

Recalling his previous thoughts in Meditation Two, the Meditator supposes that what he sees does not exist, that his memory is faulty, that he has no senses and no body, and that extension, movement and place are mistaken notions. Perhaps, he remarks, the only certain thing remaining is that there is no certainty. Although this argument often seems logical and fully-developed, Descartes uses this meditation to as inspiration prove that perhaps there is one thing that is absolutely certain in the universe: his existence.

This then leads him to question the existence of God, and then whether he himself truly exists as well. Descartes concludes his claim in stating, “So after considering everything very thoroughly, I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind,” (25). Therefore, in spite of everything he is skeptical of, Descartes manages to believe that his true existence is not something worthy of doubt.

In Meditation six: Concerning the Existence of Material Things, and the Real Distinction between Mind and Body, Rene Descartes wrote of his distinctions between the mind and the body, first by reviewing all things that he believed to be true, then assessing the causes and later calling them into doubt, and then finally by considering what he must now believe. By analyzing Descartes’ writing, this paper will explicate Descartes’ view on bodies and animals, and if animals have minds. Before explicating the answer to those questions, Descartes’ distinctions between the mind and the body should first be summarized and explained.

The existence of God has been a question since the idea of God was conceived. Descartes tries to prove Gods existence, to disprove his Evil demon theory, and to show that there is without a doubt something external to ones own existence. He is looking for a definite certainty, a foundation for which he can base all of his beliefs and know for a fact that they are true.

He cannot say that God exists, because there remains the possibility that his thoughts are in fact originating from himself (in which case there would be no need for God). Since he has abandoned all notions of existence and certainty, which includes his own body and senses, is it possible that he himself does not exist? To think a thought is bound to existence by definition; one must exist first before having the ability to think. Even if an all-powerful deceiver made it so that I do not exist, it would generate a contradiction since I cannot think that I exists if I don't. (25) Thinking about existing requires existence as a prerequisite. Descartes has arrived at his first truly tangible and useful element of truth: that it is necessarily true that he exists.

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.

Descartes' meditations are created in pursuit of certainty, or true knowledge. He cannot assume that what he has learned is necessarily true, because he is unsure of the accuracy of its initial source. In order to purge himself of all information that is possibly wrong, he subjects his knowledge to methodic doubt. This results in a (theoretical) doubt of everything he knows. Anything, he reasons, that can sustain such serious doubt must be unquestionable truth, and knowledge can then be built from that base. Eventually, Descartes doubts everything. But by doubting, he must exist, hence his "Cogito ergo sum".

Rene Descartes is a modern French philosopher, who is famous for his line, “I think, therefore I am.” The meaning of this quote is that he must exist because he has the ability to think. In Descartes most famous work, The Meditations, he starts off by doubting everything, which is known as the Method of Doubt. He believes that our senses are always deceiving us in some way and so our senses are unreliable in proving anything. By this, he means that when we use our senses, such as our vision, to look at something, the way that the object looks from afar is different from the way it looks upfront, thus, deceiving us. However, Descartes

     Through his philosophical search Descartes was able to find one indubitable certainty, that we are thinking beings. We always think, even when we have doubts that we are thinking we are still thinking because a doubt is a thought. Although Descartes found this one universal truth, he was still not able to believe in anything but the fact that he was a thinking being. Therefore he still doubted everything around him. He used this one certainty to try to find a system of knowledge about everything in the world. Descartes idea was to propose a hypothesis about something. For example he might say that a perfect being was in existence. He would go around this thought in a methodical way, doubting it, all the while trying to identify it as a certainty. Doubting everything was at first dangerous because in doubting everything he was also admitting that he doubted the existence of God, and thus opposing the church. However he made it a point to tell us at the beginning of his Discourse on Methods that what he was writing was only for himself and that he expected no one but himself to follow it (Descartes 14, 15). Descartes eventually managed to prove the existence of a higher being. He said that since he had the idea of a perfect being, then that perfect being must exist. His

The Second Meditation is one of Six Meditations by the French philosopher, René Descartes meditations were thought to have been a series of personal meditations from Descartes, with each meditation happening each day for 6 days, and in these Descartes philosophizes with ideas such as the procedure of methodical doubt, the Cogito, the arguments for God’s existence, the functions of the divinity, the independent reality of the material world, the limits of knowledge and the problem of dreaming. What was different about Modern philosophy and Descartes was how everything was derived from the ‘self’, compared to previous philosophies, for example the pre-Socratic philosophers focusing on nature. In this essay I will briefly explain the first meditation
