Personal persistence

According to perdurantist accounts of persistence, transtemporal aggregates of stages, ‘worms’, are ‘the referents of ordinary terms, members of ordinary domains of quantification, subjects of ordinary predications, and so on…on the stage view…it is instantaneous stages rather than worms that play this role’. I argue the stage theory should be preferred as an account of personal persistence. I consider the way in which four‐dimensionalist accounts of personal persistence are organized and the conditions which, arguably, any plausible account of personal persistence should satisfy. I sketch a semantics for the stage theory which yields a stage‐theoretical account of personal persistence that satisfies these conditions. I argue that standard purdurantist accounts do not. I conclude that standard purdurantist accounts fail because, while persons view themselves and their worlds from the time‐bound first‐person perspective of stages, purdurantist accounts privilege the atemporal view of persons as four‐dimensional aggregates of stages or ‘worms’. Perdurantist accounts produce counterintuitive results in fission cases because there is a discrepancy between a person's time‐bound first‐person perspective and the purdurantist view from nowhen.
