Endurantism

According to the endurantist view, material objects are persisting three-dimensional individuals wholly present at every moment of their existence, which goes with an A-theory of time.

This conception of an individual as always present is opposed to perdurantism or four-dimensionalism, which maintains that an object is a series of temporal parts or stages, requiring a B-theory of time.

The use of "endure" and "perdure" to distinguish two ways in which an object can be thought to persist can be traced to David Lewis.

[1] Thus, endurantism cannot harmonize identity with change and then cannot explain persistence clearly even if endurantists appeal to intrinsic properties.

Similarly, endurantism could find a way to bypass this problem and to reconcile the persistence of objects and intrinsic properties.
