 A central goal of ME is to determine the rules guiding practical rationality and to present these as “methods”—“rational procedures for determining right conduct in any particular case” (78). ME argues at length for the rationality of benevolence: that our actions should have “Universal Good or Happiness” as their goal (507). But, alongside this primary rule or method, Sidgwick also recognizes a secondary rule of self-love or egoism. The latter rule, he is forced to acknowledge, is equally rational: “even if a man admits the self-evidence of the principle of Rational Benevolence, he may still hold that his own happiness is an end which it is irrational for him to sacrifice to any other; and that therefore a harmony between the maxim of Prudence and the maxim of Rational Benevolence must be somehow demonstrated, if morality is to be made completely rational” (498; emphasis added).
