Abstract

In his book Objective Becoming (Skow 2015), Bradford Skow has offered a rich and systematic treatment of the passage of time. We learn much about what objective passage could and could not amount to from engaging with his careful work. Skow’s overall conclusion is that the ‘block universe’ deflationary theory of passage is stronger than any currently available version of the recently-popular moving spotlight theory of temporal passage. To help establish this conclusion, Skow provides a taxonomy of theories of temporal passage, including some new and unfamiliar theories that he classifies as versions of the moving spotlight view. These new theories are worthy of further study; however, in this commentary I will argue that they suffer from some problems that render them uncongenial to committed believers in temporal passage (Sections 2–5). I’ll also make a few brief remarks about some other arguments in the book, concerning branching time (Section 6), relativistic presentness (Section 7), and temporal experience (Section 8).
