ABSTRACT
There are two accounts of what it is for a concrete particular to persist through time: endurantism and perdurantism. The endurantist claims that for a concrete particular to persist through time is for it to exist wholly and completely at different times. The perdurantist, by contrast, denies that it is possible for numerically one and the same concrete particular to exist at different times. On this view, a concrete particular is an aggregate or whole made up of different temporal parts, each existing at its own time; and for a particular to persist from one time to another is for it to have different temporal parts existing at those different times.
