Four non-Cartesian conceptions of a person are considered. I argue tor one of these, a position called animalism. I reject the idea that a (human) person coincides with, but is numerically distinct from, a certain human animal. Coinciding physical beings would both be psychological subjects. I argue that such subjects could not engage in self-reference. Since self-reference (or the capacity tor self-reference) is a necessary condition for being a person, no physical subject coincident with another such subject can be a person. I take all of this to support the view that we (human persons) are identical with human animals.

It no longer is true in a metaphorical sense only that a person can have a change of heart. We might grant this much — allow that a person may have one heart at one time and have another heart at still another time — and also resist the idea that a person can have a change of mind in anything other than a qualitative sense. In the discussion that follows, this standard view of the matter is called into question. If the argument presented here is sound, it can happen both that one person has numerically different minds at different times and that different people have the same mind at different times. These possibilities, as I take them to be, call for reassessment of some well entrenched assumptions concerning personal identity and responsibility. In particular, they suggest that it may not be true that person A bears responsibility for making decisions person B previously made only on the condition that A is the same person as B.

Two recent papers by Michael Burke bearing upon the persistence of people and commonplace things illustrate the fact that the quest for synchronic ontological economy is likely to encourage a disturbing diachronic proliferation of entities. This discussion argues that Burke's promise of ontological economy is seriously compromised by the fact that his proposed metaphysic does violence to standard intuitions concerning the persistence of people and commonplace things. In effect, Burke would have us achieve synchronic economy (rejection of coincident entities) by postulating strongly counterintuitive transtemporal claims of numerical diversity. The argument is made that the price of Burkean economy is too high.
