This paper argues that there are practical problems of such a kind that neither impartial morality nor rational choice theory can provide us with comfort and guidance in our attempt to make the right choice if confronted with such a problem. It argues that both morality and rational choice theory are bound to misconstrue problems of this kind. Appreciating the limits of both morality and rational choice theory, as currently discussed in the literature (Wolf, Morton, Pettit, Hollis & Sugden), enables (...) us to identify the features of these particular practical problems, and allows us to elaborate the idea of an alternative of oneself, which is crucial to a proper understanding of the kind of practical problem the paper draws attention to.
