René Descartes Does Not Reject Sense Perception Essay

Descartes is now clear on his perception of God so he looks at material things. He points out that a body must exist in reality, because for him to dream about his body, it must exist before he would know what to dream about. So although he can perceive qualities of material things, he is still confused about some things because of is imperfect perception. He concludes that the senses are meant to help him get around in the world, not to lead him to the truth. ( SparkNotes Editors, 2012 )

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

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.

Despite this problem, we believe it is the same piece of wax we see, touch, or imagine. But it is not our feelings or imagination that gives us the idea. If we had evaluated these abilities, and if the wax is distorted, we would not be able to agree that it is the same wax. This study enables us to recognize that the imagination, just like sensation, does not convey the true nature of wax; rather, this difficulty indicates that only understanding, exercising its powers of conception and judgment, performs the unifying function that constitutes the self-identity of the piece of wax: “our perception of the wax is neither a seeing, nor a touching, nor an imagining… but the mind alone” (68). Although the changing characteristics of the body has been transported through our senses and imagination, the identity of the matter is provided by the understanding of the wax itself. This analysis confirms Descartes’ view that “what we thought we had seen with our eyes, we actually grasped solely with the faculty of judgment, which is in our mind” (68). Therefore, any sense of the body is actually an introspection of our mind, not an external inspection.

Descartes’ argue that mind is better known than body by first claiming humans as fundamentally rational, meaning “a thing that doubts, understands, affirms, denies, is willing, is unwilling,” ( Descartes, 19) he therefore argues that humans have the ability to know their proper minds clearly and distinctly. He proposes the conception of the mind where the imagination and the senses are also inherent capabilities of the body (faculties), specifically powers of the mind.

     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 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 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.

He finds it plausible that we are all living in a dream and we have never experienced reality. He can no longer give any credence to his senses and finds himself in a place of complete uncertainty. Descartes comes to the conclusion that nothing can be perceived more easily and more evidently than his own mind. He has discovered that even bodies are not accurately perceived by the senses or the faculty of imagination, and are only accurately being perceived by the intellect. He also realizes that they are not distinguished through being touched, smelled, or tasted, but by being understood alone. (An apple is an apple because our mind tells us that it is an apple.) It is the faculty of reason that gives the knowledge and lets the mind know the truths and essences of objects. Descartes assumes that all of us can be decided by our senses, someone can see something far away, and then discover that is not what we thought it was. Or even a oar when is immerse half in water attempt to be bent, but instead is straight. Descartes think that we cannot always be sure of what we sense, and gives the example of himself seated by the fire.

The concept of mind and body interactions has been debated among many modern philosophers. Some believe that our minds and bodies are different things, thus existing separately, while others believe that they exist as a whole. In this paper, I will be introducing two rationalist philosophical views regarding this topic, one which is by Rene Descartes and the other by Gottfried Wilhelm Leibniz. Rationalists, in philosophical terms, are the ones who obtain their knowledge through reasoning rather than the human senses. Descartes and Leibniz both have similar perspectives, but Leibniz takes a slightly different approach to improve Descartes’ argument. This paper will first show Descartes’ original argument, an example that proves the argument to be invalid, and then lastly, a revised version of the argument with Leibniz’s help.

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.

This paper will attempt to explain Descartes’ first argument for the distinction that exists between mind and body. Dualism is a necessary aspect of Descartes’ metaphysics and epistemology. This distinction is important within the larger framework of Meditations on First Philosophy (1641) because after doubting everything (body, extension, senses, etc.), Descartes comes to the conclusion that because he doubts, he must be a thinking thing and therefore exist (p.43). This means that the mind must be separate and independent from the body. One can doubt that the body exists while leaving the mind intact. To doubt that the mind exists, however, is contradictory. For if the mind does not exist, how, or with what, is that doubt being accomplished.

Before these changes were apparent, Descartes pointed out the difficulties of relying on the senses, of the physical body. In section 31 of Meditation two, he says that the perception he has, "is a case not of vision or touch or imagination - nor has it ever been, despite previous appearances - but of purely mental scrutiny". Descartes shows that our senses cannot be used to have knowledge of things in the external world, and that knowledge of these things must come through the mind alone.

In Meditation Six entitled “Concerning the Existence of Material Things, and Real Distinction between the Mind and Body”, one important thing Descartes explores is the relationship between the mind and body. Descartes believes the mind and body are separated and they are two difference substances. He believes this to be clearly and distinctly true which is a Cartesian quality for true knowledge. I, on the other hand, disagree that the mind and body are separate and that the mind can exist without the body. First, I will present Descartes position on mind/body dualism and his proof for such ideas. Secondly, I will discuss why I think his argument is weak and offer my own ideas that dispute his reasoning while I keep in mind how he might
