A preliminary hearing is held in the lowest local court (municipal or police court), but only if the prosecutor has filed the charge without asking the Grand Jury for an indictment for the alleged crime.
On the one hand, Descartes argues that the mind is indivisible because he cannot perceive himself as having any parts. On the other hand, the body is divisible because he cannot think of a body except as having parts. Hence, if mind and body had the same nature, it would be a nature both with and without parts.e reaches this conclusion by arguing that the nature of the mind (that is, a thinking, non-extended thing) is completely different from that of the body (that is, an extended, non-thinking thing), and therefore it is possible for one to exist without the other.
First he decides he can be certain that he exists, because if he doubts, there must be a thinking mind to do the doubting. He does not yet accept that he is a thinking mind inside a body. After all, the demon could have convinced him that his body and the physical world exist.escartes concedes, however, that though what he perceives with his senses may be false, he cannot deny that he perceives. So the human mind is capable of both thought and perception. He explains this using the example of a piece of wax. We understand that solid wax and wax melted by a candle are both wax.
