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.
But in order to further clarify this "thing that thinks,” he admits that there is always the possibility that he may be dreaming or deceived by an evil demon, since he is something that also imagines and senses seen. (13,15). He elaborates on this idea that if he is after all dreaming or being deceived by an evil demon, he can still imagine things and he still appears to hear and see things. In other words, his sensory perceptions, that which corresponds to his body, may not be “veridical,” but they are regardless still a part of the same mind that thinks. After proving that the senses, cannot be trusted he similarly concludes the imagination can neither be trusted. The imagination can come up with many false ideas, therefore the imagination cannot be the guide to knowing the essence of his own self. At first Descartes does not understand why he has such a difficult time identifying what is this “I” that thinks.
To better define himself, Descartes elaborates on the example of wax. How does one come to understand and know a piece of wax, is it by means of the senses or something else? He reflects on what he can know about the piece of wax and determines that wax is not wax simply due to its color or shape, since all of these things can change and the substance w...

...e about the mind than about the world outside the mind. In my opinion this is not a strong argument unless every imaginative thought, perception, or idea was able to inform one something new about the mind, rather than simply support previous things already known. According to Descartes his thoughts are only implying one thing, that one exists, and that that existing thing is capable of thinking. Descartes needs to better explain particularly hoe every new thought makes the mind better known than the body. If he claims that mind is better known than the body, he is not accounting for all the things that are still unknown about the mind, since no one can be sure that they know everything about the mind. Therefore Descartes’ claims that the mind is not also a corporeal thing, but only a thinking thing cannot be valid unless every single thing about the mind is known.
Descartes' error, Antonio Damasio tells us, was his belief in "the abyssal separation between body and mind . . . " (250). As Damasio notes, there are certainly many specific "errors" in Descartes' writings--that heat causes the circulation of the blood, for example, or that movement is translated instantaneously through the plenum from one object to another--but all these notions have been "corrected" by subsequent theory in ways that we can imagine Descartes himself might easily accept. The "abyssal separation" persists as the central cliché of modern philosophy because we do not yet agree on a solution, and Descartes serves as the convenient scapegoat for those who want to argue for the reduction of mind to matter. Damasio himself is part of a new generation of neuroscientists who, using the framework of connectionism or neural network theory, think they posses a solution to the mind/body [End Page 943] problem. The actual object of his attack is thus not so much Descartes but those cognitive psychologists who have defined themselves in terms of a Cartesian "nativism" or doctrine of innate elements of knowledge not derived from sensation. None of these "nativists" literally believes in mind/ body dualism, but insofar as they cling to the central functionalist dogma that mind can be instantiated in any physical system they de facto treat mind as something that can be considered apart from embodiment, and they embrace, more or less, an overtly Cartesian methodology, which Jerry Fodor has called "methodological solipsism." 1
This idea begins the philosopher’s ongoing discussion on the body and the mind. The first thing he must do is prove he exists beyond a doubt. Descartes declares, “If I convinced myself of something then I certainly existed” (4). This idea rests on the ability of his mind, if he did not actually exist, he would not be have any sort of mental activity. From this early point in the text, Descartes foregrounds the superiority of the mind. As Blackburn puts it, “he is forced to recognize that his knowledge of his self is not based on knowledge of his embodied existence” (20). For Descartes, the ability the think defines the self (the mind/soul)– he cites thought as the one thing that cannot be separated from him. He believes if he stopped thinking he would stop existing. His ability to think sustains him, at this point in his meditations he is only a mind, his mental existence is the only thing he has
In conjunction with this theory, any matter is known through the mind. This reasoning was used as a basis toward the dualism of the mind and body. The mind is a thinking entity. It has the ability to imagine, dream, and ultimately encompass the aspects that are not fundamentally matter. The body exists outside the mind. It is the connection to the external world based on the scientific properties of mass, size, shape, and motion. Descartes argues that the mind is distinct from the body. The mind thinks and does not have scientific properties. One’s body is a non-thinking thing. This distinction leads Descartes to conclude that the mind is not the same as the body. There is no characteristic that is categorized as both mind and body; the body can be changed, the mind cannot. In continuation, the mind can exist without the body and the body can exist without the mind since each thing is distinct. Descartes later explains how the brain is not the same as the mind. The brain is the connection between the mind and body in a human being. Descartes argues that matter cannot be the same as anything mental. The mind is affected by the brain, providing one with insight into the external world. Also, the mind can influence the brain, hence one’s body being controlled by the mind. However, it is possible for the brain to cease functionally and the mind to still operate. Essentially, one can conclude that the
Descartes claims that intellect as thinking being extended as to the Aristotelian claiming intellect as a thought. He claims that there must be a conception of what the thing that thinks underlies the Cogito inference in which registers these sufficient grounds. He establishes this argument by suggesting that it must exclude anything that requires the existence of anybody from the essential properties of the ‘they’ that thinks. Therefore claiming that mind is an extended thinking thing and the body being a non-extended thinking thing. He established these claims by first questioning everything he sees and doubting of everything that he sees is false and that his deceitful memory represents ever existed. Also excluding the senses and questioning
Descartes is hopeful to prove subsistence of the external world (physical objects located in space), and so he returns to a very basic stage and acknowledges the existence of minds as an immaterial substance and God. He then accepts that matter exists as long as it is not a projection of his own mind or God. As Descartes previously established the existence of God as a perfect being, he therefore has concluded that God is not a deceiver. This very clear concept leads him to accept his clear and distinct sensory experiences are a result of external objects of material nature. Once these corporeal things (objects of a tangible, material nature) can be considered as self-evident ideas, they can no longer be products of the mind or God.
For thousands of years, the nature of human intelligence has been debated, discussed and examined. Descartes’ argument that it is not bodies that think, but an immaterial substance that exists non-spatially is problematic because it vies thinking from a flawed, incomplete understanding of the human brain and its functions. Descartes would defend his claim by arguing that the thinking soul connects to the body through the brain, and while influenced by the states of the brain, exists outside of our bodies, however that would still be ignoring years of study and scientific evidence exploring the brain. The argument that the soul is what thinks, and would therefore makes artificial intelligence impossible is highly flawed.
This radical separation of mind and body makes it difficult to account for the apparent interaction of the two in my own case. In ordinary experience, it surely seems that the volitions of my mind can cause physical movements in my body and that the physical states of my body can produce effects on my mental operations. But on Descartes's view, there can be no substantial connection between the two, nor did he believe it appropriate to think of the mind as residing in the body as a pilot resides within a ship. Although he offered several tenatative suggestions in his correspondence with Princess Elizabeth, Descartes largely left for future generations the task of developing some reasonable account of volition and sensation, either by securing the possibility of mind-body interaction or by proposing some alternative explanation of the appearances.
Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.
One of the ways in which Descartes attempts to prove that the mind is distinct from the body is through his claim that the mind occupies no physical space and is an entity with which people think, while the body is a physical entity and cannot serve as a mechanism for thought. [1]
In the Sixth Meditation, Descartes makes a point that there is a distinction between mind and body. It is in Meditation Two when Descartes believes he has shown the mind to be better known than the body. In Meditation Six, however, he goes on to claim that, as he knows his mind and knows clearly and distinctly that its essence consists purely of thought. Also, that bodies' essences consist purely of extension, and that he can conceive of his mind and body as existing separately. By the power of God, anything that can be clearly and distinctly conceived of as existing separately from something else can be created as existing separately. However, Descartes claims that the mind and body have been created separated without good reason. This point is not shown clearly, and further, although I can conceive of my own mind existing independently of my body, it does not necessarily exist as so.
Descartes was incorrect and made mistakes in his philosophical analysis concerning understanding the Soul and the foundation of knowledge. Yes, he coined the famous phrase, “I think therefore I am,” but the rest of his philosophical conclusions fail to be as solid (Meditation 4; 32). Descartes knew that if he has a mind and is thinking thoughts then he must be something that has the ability to think. While he did prove that he is a thinking thing that thinks (Meditation 3; 28), he was unable to formulate correct and true philosophical arguments and claims. For instance, his argument for faith that a non-deceiving God exists and allows us to clearly reason and perceive was a circular argument. Another issue with Descartes' philosophy is that he wanted to reconcile scientific and religious views, which is wrong since the two maintain completely different foundational beliefs and they should exist exclusively- without relation to the other. Thirdly, he believed that the mind was the Self and the Soul, failing to recognize that humans have bodies and the outside world exists, and through which we gain our knowledgeable. Lastly, Descartes argues that ideas are all innate while they actually are not- we gain knowledge through experience.
But his habitual ideas and opinions are still present no matter how hard he tries not to present them, to solve this problem he decides that all of his opinions are false. Descartes finds himself certain about one thing that nothing is certain. Resorting back to the idea that his senses are the only way he is able to obtain the truth in life, he believes that his senses are apart of his mind and body. He uses a honeycomb to examine this topic that the body and mind are one. The wax changes shape therefore he uses imagination to understand it
...nclude, Ryle is correct in his challenge of Descartes’ Cartesian dualism, the mind and body are not two separate parts as dictated by dualist, rather the working of the mind are not distinct from the body. As a result, an observer can understand the mind of another through the actions of the body. It is the combination that makes up a human, human, as they are one and the same.
Descartes is a very well-known philosopher and has influenced much of modern philosophy. He is also commonly held as the father of the mind-body problem, thus any paper covering the major answers of the problem would not be complete without covering his argument. It is in Descartes’ most famous work, Meditations, that he gives his view for dualism. Descartes holds that mind and body are com...
...ning of mind is something that cannot be divisible but that is hard to see because I have already proved that by my understanding of the mind it has parts. It is also hard to think of a mind or soul that does not have such things as memory and personality therefore I believe Descartes argument is false.
