Metaphysical Egoism and Personal Identity

Metaphysical egoism pursues what Gregory Kavka called ‘the reconciliation project’ (roughly, the project of reconciling the demands of morality with our rational self-interest) by appealing to one version of the psychological approach to personal identity. I argue that, for reasons related to its commitment to an implausible understanding of the notion of a psychological connection, this form of egoism is not plausible. I also explore one way in which metaphysical egoism may be amended, but I ultimately reject it.
