ABSTRACT
This chapter shows that the biological animalists' response to the transplant intuition is unconvincing, and the additional arguments against the psychological approach answerable by a hybrid theorist. It provides a further understanding of the biological animalist view. The biological animalist approach is therefore inconsistent with any form of the psychological-continuity view, including the hybrid view to be defended. According to the biological animalist, things of very different kinds can be persons, and the persistence conditions of a person of a particular kind will depend on the kind. Many defenders of animalism will resist the formulation as being too weak and failing to capture the distinctive philosophical interest animalism is supposed to have. The biological property of the biological animal is more tied to the persistence through time of its possessor than the biological property of the dog, though the two properties have the same name.
