Author’s Abstract

  1. I contest the following assumptions regarding the conditions of diachronic identity for natural kind1 members:
    1. That there is a principle whereby a and b can be located on a single continuous spatio-temporal path, and thereby be identified as stages of the same continuant particular;
    2. That the identification of a and b must be sortal-governed2;
    3. That a particular cannot change kind-membership3 without contravening its identity-conditions.
  2. I argue that these issues are best treated in terms of Derek Parfit4's 'Relation R' rather than in terms of the identity relation.
