 According to a four dimensionalist like David Lewis a table is extended through the time of its life, and constituted from temporal parts which are themselves short lived tables. As such a four dimensionalist like Lewis would not hesitate to give the following answer to the above question. The problem is, in part, a problem about whether a cup-like object that exists only at t′ is suitably related to a cup-like object, itself a proper part of a larger cup-like object, that exists only at t so that both cup-like objects are temporal stages or parts of a four-dimensionally extended cup.
