Weaknesses of Descartes' Arguments Essays

     After he has established himself as a thinking thing, he then goes on to argue that the mind is more certainly known then the body. He goes on to say that it is possible that all knowledge of external objects, including his body, could be false as the result of the actions of an evil demon. It is not, however, possible that he could be deceived about his existence or his nature as a thinking thing. This is true because if he can be deceived about anything, then he can be certain, as he is a thinking thing.

The one thing Descartes cannot doubt is that he exists, because he thinks and question the world around him. Descartes felt that our senses and perception of can skew every aspect of our understanding of reality, so only the fact that he exists is without doubt. This reasoning is known as solipsism (1). Basically, everything seen, felt, heard, or experienced are misrepresented by perception. With perception skewing everything, the only certainty is mind and the thoughts it holds, not necessarily that the thoughts are correct.

Like many people today, Descartes believed that the mind and soul were separate. He believed that the mind’s purpose was only for “thinking” and “non-extended” things. While, the body is an extension; non-thinking. Descartes thought that the mind and body were different substances, thus they

René Descartes believed that the mind and body are separate; that the senses could not always be trusted, but that because we as humans are able to think about our existence, we possess some sort of entity separate than our fleshly body. I believe this separate entity to be a soul”an immaterial and

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:

Something very essential to know about Descartes is his idea of Cogito Ergo Sum; I think, therefore I am. He believes that he exists because he is thinking, making him a thinking thing. Descartes first premise states, "I have a clear and distinct idea of myself, in so far as I am simply a thinking, non-extended thing" (Descartes, 54). The first thing that we need to understand from this premise is what Descartes means by extended; to occupy space. So, since he believes that he is not an extended thing, it follows that he does not take up space. Given this, he looked inside himself and saw no parts within his mind, no space or boundaries that his mind contains. In addition, the mind provides a place for free will and faith, which are not parts but different ways of thinking. He rationalizes this by making the mind of a qualitative substance. By saying that only things that can be measured must be of a material substance and those things that cannot be measured are of a thought like substance. The relation between body and mind now seem to be more divided since he believes that his mind is not extended. In short, this premise states that the mind has no parts, making it indivisible.

In conclusion, this paper has explained Descartes view on bodies and animals, and analyzed whether Descartes believed that animals had minds. Explanation of Descartes view of minds and bodies has been provided, indicating that he believed that the mind and body were “tightly jointed”, as well as, his view of how the body would act without a mind. From these explanations, we have been able to conclude and explain why that Descartes would believe that animal do have minds.

Descartes discusses the existence of the human mind as a separate entity from the human body, including the a passage confirming his own existence as nothing but a thinking entity, in his writing Principles of Philosophy (I. 63-65). Following his rejection of all knowledge, in order to divide what was false from what could be proven, Descartes strives to prove the existence of his own mind, as a basis from which to prove the existence of the rest of the universe. I think his premise is flawed, Through the concept of doubt, he finds a contradiction (I am thinking about not

     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

In my eyes this does not cancel out that God is real, because it is possible that at first God created everything with good intentions, and left individuals to live and react to certain situations their own ways.

Descartes concludes that the attribute of thinking is the only quality that he can justifiably claim at this point. But he is quick to point out that thinking is the only attribute about which he is sure; not that thinking is the only attribute that he has. Nevertheless, this is the starting point of a radical ontological distinction that carries Descartes through his Meditations. That distinction is between a "thinking thing" and a corporeal body. The two are mutually exclusive. A "thinking thing" is nonphysical or spiritual in nature, whereas a corporeal body is physical, but not capable of consciousness or thought. For Descartes, a "thinking thing" is consciously aware of what is around it and doubts, understands some, is ignorant of most, imagines, and feels.

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

While numerous philosophers have debated how to quantify personal identity, It is my contention that Rene Descartes presents the best argument .This essay will examine the strengths and weaknesses within his theory. This essay will also also compare Descartes argument to Rick Parfit and David Humes individual interpretations of what personal identity is. Lastly, this essay will examine the weaknesses within Descartes argument and the points some have contention with.

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).

‘Cogito Ergo Sum,’ - ‘I think therefore I am ‘ one of the most famous and well known quotes or arguments in all of modern philosophy; a phrase instantly recognizable to all those studying in the field of philosophy. This phrase refers to an attempt by Descartes to prove with absolute certainty his own existence; a systematic way to philosophize. The argument, while first proposed by ancient philosophers such as Aristotle and Saint Augustine, was utilized as an argument by French philosopher Rene Descartes in his influential text “Meditations on First Philosophy“. This argument appears in the books second meditation and provides the cornerstone for Descartes argument in the following five meditations and serves as the basis for Descartes overall metaphysical thesis, without which Descartes reasoning system would collapse. Throughout this paper I will
