The thought experiment proving you're not made of the same stuff you were, you're just the same story.
means A thought experiment asking whether an object that's had every one of its original parts replaced is still, in any meaningful sense, the same object.
from Named for the actual ship said to have been preserved by the Athenians, who replaced its rotting planks one by one over time — until, as Plutarch recounts in his Life of Theseus, philosophers argued over whether it remained the same ship at all. Plutarch wasn't inventing the puzzle so much as recording it as already debated; later philosophers (notably Hobbes, who added a twist involving the discarded original planks being reassembled) picked it up and ran with it. So the paradox is ancient, but the fame of its name is really a relay race of philosophers retelling an old Greek dock story.
