Philosophy

The Metaphysics of Material Constitution and the Ship of Theseus

Quick fact

The Ship of Theseus paradox, described by Plutarch, has been debated for over two millennia; some philosophers argue the rebuilt ship is a different object, while others claim it remains the same, and a few say the puzzle disappears under four-dimensionalism.

Why this is interesting

You watch your favorite wooden ship, plank by plank, replaced over decades—until not a single original board remains. Is it still the same ship?
