 (See Plutarch, Life of Theseus.) Imagine a wooden ship restored by replacing all its planks and beams (and other parts) by new ones. Plutarch reports that such a ship was “… a model for the philosophers with respect to the disputed arguments … some of them saying it remained the same, some of them saying it did not remain the same” (cf. Rea 1995). Hobbes added the catch that the old parts are reassembled to create another ship exactly like the original. Both the restored ship and the reassembled one appear to qualify equally to be the original. In the one case, the original is “remodeled”, in the other, it is reassembled. Yet the two resulting ships are clearly not the same ship.
