The Ship of Theseus is an artefact in a museum. Over time, its planks of wood rot and are replaced with new planks. When no original plank remains, is it still the Ship of Theseus? Secondly, if those removed planks are restored and reassembled, free of the rot, is that the Ship of Theseus? Neither is the true ship. Both are the true ship.
