Abstract

We argue that four-dimensionalists should adopt a contextualist semantics, according to which ordinary speakers’ judgments may concern person-stages, person-segments or person-worms, depending on the context. We explain how context helps select the boundaries of the temporal parts we refer to or quantify over and show that contextualism offers the best treatment of ordinary predications and ordinary counting judgments. Contextualism implies an error theory; however, we explain why this error theory is less problematic than those entailed by the worm and stage theories.
