 The extensionality objection. The second problem for the constitution view was that it allowed for two objects to be composed of all the same parts. The temporal parts theorist avoids this problem in the case of the statue and the lump, since he will say that those objects share some, but not all, of the same temporal parts. Of course, those objects will have all the same parts when they both exist, but this is no more problematic than two roads sharing all the same parts where they overlap.
