Abstract

Mellor’s theory of time includes the doctrines that (a) objectively, time does not embody tense or temporal properties other than those contained in the B-series, (b) particular objects are endurers, and (c) objectively, time does not flow. I show that these theses cannot all be true together, and that one must be rejected. Since (a) is basic to Mellor’s approach, then assuming that he would not adopt a perdurantist ontology, it follows that he should give up (c). Denying (c), however, is compatible with the essentials of his position. The falsity of (c) does not imply any version of the A-theory, and the B-theory can allow for the motion of diachronically identical entities through the dates over which their careers extend.
