Others, following hume as he is frequently interpreted, claim that morality is justified in terms of other-regarding interests, wants or intentions that people happen to have. And still others, following kant, claim that morality is justified in terms of the requirements of practical reason. In "the moral point of view" published in 1958 and in a series of articles continuing to the present, kurt baier has defended this third sort of justification for morality. In this paper, after years of respectful opposition, i join forces with baier and argue that only a justification of this third sort can be fully adequate and then only when it is developed in a certain way. I begin by showing what is wrong or defective in the other justifications. Then i consider attempts by baier and others to elaborate the third sort of justification. Drawing upon their work, i present a justification based on the requirements of practical reason that succeeds in demonstrating that the rational egoist acts contrary to reason.
