 Unfortunately, the temporal parts solution cannot be extended to the case Lumpl and Goliath since those objects exist at all of the same times and thus share the same temporal parts. The four-dimensionalist who accepts extensionality will therefore be forced to conclude that Lumpl is identical to Goliath. This, however, is problematic, since those objects seem to differ in their modal properties. Lumpl, for example, could survive beings squashed, whereas Goliath could not.
