 Among Foot’s most anthologized, celebrated, controversial, and widely cited articles is undoubtedly “Morality as a System of Hypothetical Imperatives” (1972, MSHI). In this article, Foot takes an about-face on the issue of the rationality of morality. In MSHI she retains the view from “Moral Beliefs” that self-interest is rationally required: we must have desires for what is evidently in our self-interest or else we are irrational. Yet, she drops the view that morality coincides with self-interest, and ends up with the position that morality only provides reasons if we have desires that we might rationally lack. Unfortunately, although Foot notes her change of view, she does not revisit her previous position to argue at any length against her earlier  view.[3]
