In the preceding sections of this essay, I have outlined a dialectical procedure whereby a doubting mind might be led to the recognition of moral truth. What has been given is the bare plot of a conversation between teacher and student. The student was, at the beginning, a skeptic about moral matters, denying the objectivity of moral knowledge, supposing that all moral judgments were a matter of opinion, entirely relative to the individual or to his cultural location at a given time and place. The teacher, by asking him to explain the undeniable fact that men exercise preference, gradually made him realize that his own criteria for preference — pleasure and quantity of pleasure — had a certain universal validity; and then, as a result of seeing the inadequacy of these criteria, the student began to understand that happiness, rather than pleasure, was the ultimate principle of moral judgments. The crucial steps in the argument were: (1) the distinction between pleasure as one among many objects of desire and pleasure as the satisfaction of any desire; (2) the enumeration of the variety of goods which are objects of human desire; (3) the point that only the totality of goods could completely satisfy desire; (4) the realization that this totality of goods, leaving nothing to be desired, is the end of all our seeking, and that everything else is sought for the sake of its attainment; (5) the conception of happiness as “all good things,” a whole constituted by every type of good, the complete good being the end, the incomplete good its parts or constitutive means; (6) the conclusion that the end, as the first principle in the practical order, is the ultimate criterion of preference, for preferor choice is exercised only with respect to means, and hence we should, in every case, prefer whatever is more conducive to the attainment of happiness.
