Ship of Theseus

Paradox: if you have some thing and replace all of its parts one by one, do you still have the same thing by the end?

Called, "Ship of Theseus," because Plutarch posited that the Athenians preserved the ship that Theseus used to return from Crete by replacing parts as they decayed.

The 17th century philosopher, Thomas Hobbes, played with this paradox further by asking if someone gathered all of the old parts that were replaced and rebuilt the ship with those parts in all the same places, would that then become the "original" ship? Or is it the ship the one that was preserved by repairs and replacements?
