Abstract

This chapter argues against the widely held view that the theory of relativity entails that space and time are fundamentally alike. It solves the Problem of Motion by defending a hybrid view that combines a modal account of time with substantivalism about space. This view recovers space-time at a higher level of abstraction, rather than treat it as a fundamental entity. The chapter closes with a brief discussion of the relation between space-time symmetries and the structure of space and time.
