Abstract

Stage Theory is the view that ordinary objects are instantaneous things. Nevertheless, an object O can have counterparts, which are instantaneous objects appropriately related to O. O “persists” by way of its counterparts. In this paper, I argue that stage theory implies that persons cannot do temporally extended acts, since in order to do such an act, one must do each part of the act, and no instantaneous person can do each part of a temporally extended act. Thus, since it is obvious that persons do temporally extended acts, we should reject stage theory.
