 The impenetrability objection. The first problem for the constitution view was that it allowed for two material objects to exist in the same place at the same time. The temporal parts theorist avoids this objection for he will say that, whenever Lump and David exist, there is a single object that exactly occupies the relevant location—a temporal part that is shared by both David and Lump. Of course, those two objects will be partly present at the same location, but this is no more problematic than two roads being partly present at the same place by sharing a common road segment.
