Philosophers Index Abstract

I contest the following assumptions regarding the conditions of diachronic identity for natural kind 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-governed1;
  3. That a particular cannot change kind-membership without contravening its identity-conditions.
I argue that these issues are best treated in terms of Derek Parfit's 'Relation R' rather than in terms of the identity relation.
