 Assuming that organisms persist by virtue of some sort of brute-physical continuity, animalism implies a version of the brute-physical view. Some endorse a brute-physical view without saying that we are animals. They say that we are our bodies (Thomson 1997), or that our identity through time consists in the identity of our bodies (Ayer 1936: 194). This has been called the bodily criterion of personal identity. It is obscure, and its relation to animalism is uncertain.
