Ship of Theseus

We’re going to do a thought experiment called The Ship of Theseus. Here’s how it works:

Imagine a famous ship. Over many years, every single plank of wood rots and gets replaced with a new one. Eventually, not a single original piece remains.

Is it still the same ship?

Stand up if you think yes, it’s the same ship.

Stay seated if you think no, it’s a different ship.

Now here’s the twist: Someone has collected all the old rotting planks and built a ship from them.

Which one is the real Ship of Theseus — the one that was continuously repaired, or the one made from the original parts?

This applies to you too — your body replaces almost all its cells over time. Are you the same person you were 10 years ago?
