The link between the mind and the physical brain is described by Descartes. His account is quite believable. He claims that while the mind can’t be weighed or measured, the brain can. The brain has psychical properties (such as appearances, odours, and textures), whereas the mind cannot be seen or touched. Mental processes, thought, and consciousness are all part of the mind. I believe that the mind and brain are fundamentally different, but that they cannot exist without one another. However, I do not believe that the mind and brain are identical. Descartes claims that the mind is indivisible since he cannot perceive any pieces in himself. The body is divisible, on the other hand, because he cannot imagine a body without components.
