illustrates of Move 13 — A transposition: two different move orders reach the identical position. Same place, different history. The same game?
The Ship and the Plank
Replace every plank of a ship, one by one. Is it the same ship? Replace every cell, every memory. Are you the same you?
concludes of Move 1 — Theseus's ship is whatever we keep mending.
So we are ships and rivers and repositories: kept not by our matter but by the care that keeps replacing it. Identity is not a substance. It is maintenance.
The dialogue is concluded
You are not the planks. You are the keeping.
