Eric Olson argues in The Human Animal that thought-experiments involving body-swapping do not in the end offer any support to psychological continuity theories, nor do they pose any threat to his Biological View. I argue that he is mistaken in at least the second claim.

Most philosophers in the analytical philosophy answer the question what personal identity is in psychological terms. Arguments for substantiating this view are mainly based on thought experiments of brain transfer cases and the like in which persons change brains. However, in these thought experiments the remaining part of the body plays only a passive part. In this paper I argue that the psychological approach of personal identity cannot be maintained, if the whole body is actively involved in the analysis, and (...) that the body is an intrinsic part of what I am as a person.

It is worthwhile comparing Hylomorphic and Animalistic accounts of personal identity since they both identify the human animal and the human person.The topics of comparison will be three: The first is accounting for our intuitions in cerebrum transplant and irreversible coma cases. Hylomorphism, unlike animalism, appears to capture “commonsense” beliefs here, preserves the maxim that identity matters, and does not run afoul of the Only x and y rule. The next topic of comparison reveals how the rival explanations of transplants (...) and comas are both at odds with some compelling biological assumptions. The third issue deals with our practical concerns, most notably, the possibility of an afterlife. It turns out that the hylomorphic treatment of Purgatory raises the spectra of the “too many thinkers” problem and some considerable unfairness. Contrary to expectations, an animalist insistence on uninterrupted bodily continuity between this life and the next does not involve deceptive body snatching. (shrink)
