Everyone agrees that men and women are at least identifiable with their bodies, and that to doubt that is to exhibit total ignorance. But it is controversial to say that there are minds or souls and that to doubt that is not to show one's ignorance. The arguments for mentalism are refutable. We should revise how we use these words aswell. Although we have been led to think so, there is nothing essentially private about these things.
People are capable of dissimulating and certain things are difficult to determine.
We can imagine surviving the death of our bodies. All this shows is that not everyone realizes that he and his body are one and the same thing. But this is wrong-headed. To distinguish something as a living animal, e.g., is only to call attention to the very complicated way the matter of its body is organized and to a large class of activities which result from such organization. A living body is simply one in which certain processes, some of them frightfully complex and ill understood, take place.
