In his works, Meditations on First Philosophy and The Passions of the Soul, René Descartes sets out his views on the mind. Descartes is a dualist, specifically an interactionalist, that is, someone who believes that mental states and physical states are distinct from each other, but still influence each other. This vision, however, faces significant obstacles, to which Descartes believes he has an answer. In this article I will outline Descartes' argument for the distinction between mind and body, explain the problems facing his theory, and conclude that his dualist explanation cannot survive objections. method of doubt in his research. He admits that everything he was certain of until now came from his senses, but he also realizes that his senses often deceive him. For example, when something far away seems small, but is actually large, or difficulty determining whether one is dreaming or not, are noteworthy reasons not to doubt one's senses. Then, he discusses an evil demon who has deceived him and all his thoughts, and goes so far as to doubt his senses, his body, and even mathematical truths like two plus two equals four. After fearing that without a body he too might not exist, he realizes that as long as the demon deceives him, there is one thing that is deceived, himself. Therefore, no matter what happens, he cannot doubt his own existence to the extent he thinks. Of what it exists, however, he is not sure, other than a thinking thing, a thing that "doubts, understands, affirms, denies, wills, wills not, and also imagines and has sensory perception... half of the paper.. .... a material extended thing by saying that a non-extended immaterial thing interacts with a material extended thing. Furthermore, it fails in its attempt to explain how it interacts with the rest of the body, since nerves, blood, etc. also exist. they are all physical and material substances. Although a brilliant and convincing argument, Descartes' dualism cannot survive. the two charges leveled against him. Namely, that it is impossible to conceive of something that does not exist in space and time, and that if such a thing existed, how would it interact with something that exists in space and time? His main reasoning for the distinction appears to be flawed and his solution to the interaction gets him nowhere. Therefore, we are left with the general notion that mind and body are not separate entities of different substance that influence each other.
