ABSTRACT
Bodily continuity theories identify persons with their bodies (or sometimes with their brains), and in doing so ground personal identity in facts about the diachronic identity (i.e. identity over time) of bodies (or of brains): for grey-haired Old Jack in 2010 to be one and the same person as Wee Johnny, who ran in the 1952 Olympics in Helsinki, is for Old Jack and Wee Johnny to be identical to one and the same body (or brain).
