Appraisal of René Descartes

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

For Descartes, this means that a substance is really distinct from anything else other than God whom Descartes credits as the creator of such an object. The ramification of such a principle leads Descartes to believe that the mind and body could exist completely separately of one another, allowing that God chose to create them in this particular way. Despite this, the possibility that the two could exist separately does not mean they actually do. This is an issue of its own entirely.

In his Meditations on First Philosophy, Descartes states “I have a clear and distinct idea of myself, in as far as I am only a thinking and unextended thing, and as, on the other hand, I possess a distinct idea of body, in as far as it is only an extended and unthinking thing”. [1] The concept that the mind is an intangible, thinking entity while the body is a tangible entity not capable of thought is known as Cartesian Dualism. The purpose of this essay is to examine how Descartes tries to prove that the mind or soul is, in its essential nature, entirely distinct from the

Descartes concludes from his first meditation that he is a thinking thing, and as long as he thinks, he exists. In the second meditation, Descartes attempts to define what the “thinking thing” that he concluded himself to be in the first meditation actually was. Descartes’ determines that he gains knowledge of the world, that is, knowledge that is separate from the mind, through the senses; and that the senses can deceive. This he outlines within the first meditation, and mentions on the second meditation. Furthermore, in the second meditation, Descartes refuses to define himself as a rational animal, instead going back and relying on labeling him mind as a thinking thing. In the fifth and sixth paragraphs of the second meditation, Descartes distinguishes the body from the soul. Descartes indicates that there is the presence of the body, and it seems to be in the physical world, but he also notes that his mind does not seem to exist in the same manner. Descartes also claims that the ability to perceive is a power of the soul, but inoperable without the body. Descartes then explores another object with physical substance, which is a piece of wax. The piece of wax is undeniably physical; it takes up space within the material world. The body falls into the category, just as any other physical object in the material world. The main point of Descartes’ second meditation is that any given person can know more about their mind than of the world surrounding them.

As Descartes defines the mind and body, as clearly and distinctly separate entities with mental and physical properties, only when considered separately from each other. But then they cannot without irrationality also be considered as united, for this would be to consider them at the same time as two different and one single substance, which, as Descartes admits,

     This is where the wax argument comes into play. All the properties of the piece of wax that we perceive with the senses change as the wax melts. This is true as well of its primary properties, such as shape, extension and size. Yet the wax remains the same piece of wax as it melts. We know the wax through our mind and judgement, not through our senses or imagination. Therefore, every act of clear and distinct knowledge of corporeal matter also provides even more certain evidence for the existence of Descartes as a thinking thing. Therefore his mind is much clearer and more distinctly know to him than his body. At this

As the first “premise” of his proof Descartes makes a very important distinction between the various types of ideas. The first type of idea he discusses is ideas that are images of things. This type of idea, when thought of, is apprehended as an object of my thought, but there is something more embraced in the thought than merely the representation of the object. Now if these ideas are considered only in themselves, and are not referred to any object beyond them, they cannot, properly speaking, be false. This even applies to the will and affections, a second type of idea, for although I may desire objects that are wrong, it is still true that I desire them. The third type of idea is that of judgement. Descartes goal in this classification is to find in his mind which of the ideas are the proper bearers of truth and falsehood. Considered in themselves, ideas are not false nor are desires. The only place where mistakes can be made is in making judgements. As Descartes says, “And the chief and most common mistake which is to be found here consists in my judging that the ideas which are in me resemble, or conform to, things located outside me.” Descartes further classifies his ideas by their origin: those that appear

that you exist is proof that you in fact exist as how can you doubt

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.

Descartes dualism proposal is an interesting concept due to its simplicity. Yet, being so simply makes one more and more want to dismiss. His argument begins with what is known as Real Distinction. This is the term used to describe a substance or non-physical object that exists on due to the help of a higher being or power—be it God or science, though Descartes would likely argue for God. The mind, in Descartes view, can only exist because of this higher power. One knows the mind exists simply due to being able to ask the question of its existence. However, to prove that the body exists one must think about the physical nature, shape, and sensations of said body. In Descartes sixth meditation he discusses the idea that a person can conceive their mind without their body, but cannot conceive of the reverse. This argument seems to be the most sounds.

The next task that Descartes must consider is to define what he is, and in doing so be careful not to make assumptions. He cannot consider himself to be an animal, since that would require a definition of what an animal is. Such an examination is beyond the discussion. (25) Instead of making random guesses, Descartes begins to think about what came to mind when he considered what he was. (25, 26) The first thought that occurs to him is that he has a body - something that by definition has a determinable shape, defined location and that can occupy space. However, if an all-powerful deceiver is at work, then that which

Some have suggested that René Descartes argues that sense perception relies on the mind rather than on the body. Descartes asserts that we can know our mind more readily than we can know our body. In support of this idea he gives the example of a piece of wax which is observed in its solid form and its liquid form. After pointing out the difficulties of relying on the senses of the physical body to understand the nature of the wax he makes this claim: [P]erception ... is neither a seeing, nor a touching, nor an imagining. ... [R]ather it is an inspection on the part of the mind alone (Section 31). 1 This quote is perhaps the most direct statement of the author's thesis on this subject.

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

To support his claim of dualism, Descartes presents a number of arguments that attempt to prove that the mind is separate from his body. Two of his strongest points are from the conceivability argument and divisibility argument. Further reinforcement of his claims comes from the idea of privileged first-person access, where he concludes that only an individual has full access to his own thoughts and state of mind.

Descartes has a very distinct thought when thinking about the mind, and how it relates to the body, or more specifically then brain. He seems to want to explain that the mind in itself is independent from the body. A body is merely a physical entity that could be proven to be true scientifically and also can be proven through the senses. Such things are not possible with the meta-physical mind because it is independent of the body. Building on his previous premises, Descartes finally proves whether material things exist or not and determines whether his mind and body are separate from each other or not. In Meditation Six, Descartes lays the foundation for dualism which has become one of the most important arguments in philosophy.
