Abstract

Ted Sider’s book makes a beautifully presented and compellingly argued case for four dimensionalism. Most of the arguments for four dimensionalism to be found in the literature seem to me to be uncompelling. Ted’s argument from vagueness, given in the last section of chapter 4, is a notable exception. After discussing that argument I will respond to his objections in section 5 chapter 5 to my own temporary identity view.
