- Instantaneous(describing temporal parts that exist at just one moment)
- Existing or occurring at a single moment in time with zero duration, like a snapshot rather than a video.
- Ontology(Carnap argues this enterprise is based on a mistake)
- The philosophical discipline that tries to answer hard questions about what there really is.
- Property-bearer(describing what temporal parts are in this theory)
- Something that possesses or holds properties; basically, a thing that has characteristics or qualities.
- Robust(in the discussion of mathematical properties)
- Strong, reliable, and stable—something that doesn't break or change significantly when conditions vary slightly.
- Sider(as the philosopher whose theory is being discussed)
- Theodore Sider is a contemporary philosopher who studies metaphysics—the nature of reality—and has developed influential theories about how objects exist through time.
- Temporal parts(Four-dimensionalist solution to the problem of change)
- Distinct stages of a temporally extended object, such that the puppy Oscar and the old gray-muzzled Oscar are distinct parts of the whole Oscar
- four-dimensionalism(metaphysics of identity and time)
- The philosophical view that objects (including people) are made up of temporal parts or stages, just like a physical object has spatial parts; you exist across time like a movie reel exists as many frames.
- intrinsic property(Contrasted with relational property in the analysis of molecular shape)
- A property possessed by an object independently of its relations to other things
- perdurance(Lewis's account of change)
- The account on which objects persist by having distinct temporal parts at different times
- presentism(Philosophy of time)
- The view that, necessarily, it is always true that only present objects exist; no objects exist in time without being present
