In this paper, I argue that standard psychological continuity theory does not account for an important feature of what is important in survival – having the property of personhood. I offer a theory that can account for this, and I explain how it avoids the implausible consequences of standard psychological continuity theory, as well as having certain other advantages over that theory.

What makes a person the same over time is a question dealt with by many philosophers. I too offered a purely metaphysical answer in a different work, however, as with many other theorists, I offered an answer outside of considering the political consequences of the theory I offered. Upon reflection, I now see that this was a mistake in need of correction. This is because I believe that conceptually a theory about how a person remains one and the same over (...) time presupposes an understanding of the nature of personhood as an ontological kind. That is, to remain the same person over time logically requires remaining a person. While being a counting as a person is a purely metaphysical matter, the fact is having the status of being a person is highly significant both morally and politically, as any social movement fighting for being granted this status to groups of individuals who have been denied it. To ignore the moral and political consequences of a metaphysical theory of persons is therefore ethically irresponsible. I argue that many of the assumptions concerning personhood are ethically and politically biased in favor of a conception of persons that disadvantages certain individuals, and that examining and correcting these biases is essential to be ethically responsible theorists of personhood.
