I have argued that a strong form of physicalism is the truth about ourselves. The answer to the question, “What am I?” is probably, “A wholly physical thing”. Since we concluded in Chapter 5 that our mental states – our thoughts, experiences and feelings – are identical with physical events in the brain, there is no scope for people themselves to be other than physical things. In this chapter we shall consider the various possible criteria of identity (over time) for physical selves, and we will raise the question whether it is possible, as physicalists, to hope for some kind of life after death.
