In the philosophy of time, '''four dimensionalism''' is a term sometimes used to refer to the view that the past, present and future are all equally real, and that (tenselessly) there exist dinosaurs, people and (if there will be such things) cities on Mars. These things don't exist ''now'' but they do exist, with the analogy often being that, if I am in London, New York doesn't exist ''here'' even though it does exist. It is to be contrasted with presentism. 'Four dimensionalism' is also sometimes used to refer to this view ''plus'' the B-Theory of time.

But sometimes the term is instead used to refer to the view that objects persist by having temporal parts.

Der '''Vierdimensionalismus''' ist eine bestimmte Position der konstituiert sind. Beide Verwendungen können unterschieden werden oder in Verbindung miteinander vorkommen. Gegenthesen zum Eternalismus sind der Präsentismus (nur Gegenwärtiges existiert) und der Possibilismus (auch Vergangenes, nicht aber Zukünftiges existiert, da die Zukunft noch offen ist in dem Sinne, dass unterschiedliche Alternativen metaphysisch möglich sind).
