The book contains six different meditations and opens with Descartes discarding away all information and knowledge he had ever known before. This laid ground for him to begin a new search for knowledge and wisdom. The distinction between mind and body and the existence of other material things is the last piece of meditation in the book (Rozemond, 2006).
The sixth meditation deals with the existence of material things and the difference between mind and body. This meditation has two main arguments that Descartes uses to prove that the mind and the body are two distinct realities. The first argument states that since it is possible to conceive the mind and the body as two different things, God can cause them to exist independently. This argument fulfils the traditional criteria for metaphysical real distinctions. The second argument states that while the body is divisible, infinite and extended into space, the mind is unitary, indivisible and un-extended into space. These two distinct natures of mind and body distinguish the two elements as distinct and independent realities.
In this meditation, Descartes attempts to find proof about whether material things can exist out of self and God. He then proceeds to prove that the mind is distinct from the body. With regard to the latter, Descartes begins his proof by asserting that God is capable of creating anything that Descartes himself can clearly and distinctly perceive. He follows this argument by stating that if God is capable of creating things that are independent of the other, then such things are distinct and different from each other.
