The Ship of Theseus
Captions available
The idea
The ship of Theseus: replace a ship's planks one at a time until none remain—is it the same ship? Gradual replacement strains identity.
In practice
Sharpen it: reassemble the discarded planks into a second ship. Two candidates, one history, and a verdict owed to each.
