“The ship wherein Theseus and the youth of Athens returned … was preserved by the Athenians … for they took away the old planks as they decayed, putting in new and stronger timber in their place, insomuch that this ship became a standing example among the philosophers, for the logical question of things that grow; one side holding that the ship remained the same, and the other contending that it was not the same.”
– The Paradox of Theseus’s Ship, from Plutarch’s Parallel Lives, written in 75 A.D.
