Four-dimensionalism

Four-dimensionalism is a philosophical theory regarding the nature of objects and time, particularly in the context of metaphysics. It posits that objects are not just three-dimensional entities existing in space, but also have an extension in time, thus making them four-dimensional. In essence, four-dimensionalism suggests that objects should be understood as 'four-dimensional entities' that persist through time by having temporal parts, much like they have spatial parts.
