James Baillie finds this counterintuitive; to avoid it he holds that the identity of these things is governed by Andrew Brennan's survival relation (a generalization of Derek Parfit's relation R). Wiggins' theory is defended here by appealing to his conceptualism, which correlates criteria of identification with conditions of identity, and by arguing that since the survival relation is one-to-many it cannot supply criteria of identification for epistemically primary things, which natural things are presumed to be.</ol></FONT> <U>Second Abstract</U><FONT COLOR = "800080"><ol type="1">Discusses two different philosophers' points of view regarding their theories of identity and <a name="2"></a><A HREF="../../Notes/Notes_0/Notes_27.htm">natural kinds</A><SUP>2</SUP>.
