 Endurantism, Endurantism or Endurance Theory is a Philosophical Theory of Persistence and Identity. According to the Endurantist view, material objects are persisting three-dimensional individuals wholly present that have moment of their existence, which goes within a theory of time. This conception of an individual as always present is opposed to Perjurantism or for Dimensionalism, which maintains that an object is a series of temporal parts or stages, requiring the beat theory of time. The use of Endurer and Perjurer to distinguish two ways in which an object can be thought to persist can be traced to David Lewis.
