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 at every moment of their existence. 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. 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.

Subsistence, Substance. The former of these words is derived from the verb subsisto, which among its shades of meaning signifies to remain. A thing subsistens per se is therefore something which has endurance in itself. Substance is derived by St. Augustine from the same verb; but by the majority from substo, to stand under. A thing substans therefore is that which is standing under attributes or accidents, that of which they are the attributes or accidents.

Przy tej wersji warto-by rozważyć jakiś przymiotnik (przydawkę) poprzedzający-ą.

SURVIVAL oczywiście też wchodzi - w pewnych kontekstach- w rachubę.

DWA zaproponowane słowa to swego rodzaju także gra językowa- rymują sie. Akurat nie to jest tu najważniejsze-tylko spójność znaczeniowa, ale i ten fakt można wziąć pod uwage przy wyborze/ doborze odpowiedzi.
