The Ship of Theseus
is it still the same ship?
The ship of the hero Theseus is kept in a harbor. As planks rot, they are replaced one at a time, until eventually no original plank remains. Is it still the ship of Theseus? And if someone collects all the old planks and rebuilds a ship from them, which one is the real ship?
