People are organisms of a characteristic shape, with individual personalities, abilities and memories. Each of these features varies through time, but does not normally change very abruptly before death. Because these changes are only gradual, we are able to pick out one and the same individual through time, and refer to him, her or it by use of a proper name, just as we are able to refer to one and the same planet, animal or building. In particular, organisms change (...) shape only gradually, and we have every reason to believe in the possibility of our continuing to watch the spatiotemporally continuous life-history of one and the same organism.

In Book IV of The Odyssey , Menelaus tells Telemachus as much as he knows of Odysseus' wanderings. He reports that Odysseus, wanting to learn the end of his travels and needing directions for returning safely home through the dangerous seas, captured Proteus and held fast to him, though Proteus transformed himself into a bearded lion, a snake, a leopard, a bear, running water and finally into a flowering tree. Proteus eventually wearied, and consented to tell Odysseus something of what (...) he wished to know. (shrink)

I defend the claim that bodily continuity is the primary criterion of personal identity by arguing there is an important sense in which it (unlike rival criteria) is a necessary condition of such identity. This claim is shown to be misunderstood in recent discussions because of a confusion of it with the claim that bodily continuity is a sufficient condition of personal identity. In the course of my argument, I criticize williams, Shoemaker, Puccetti, Quinton, Miri, And others.
