The difference of the evolutionist view from utilitarianism comes out at another point. The latter places the standard and test of conduct in its effects on the sensibility. The best is that which brings most pleasure. Utilitarians are now, for the most part, ready to admit that, to be in earnest with their theory, they must reject Mill's attempt to distinguish qualities among pleasures. "If morality is to be defined by happiness, we must, of course, allow all kinds of happiness to count, and to count equally so far as they are actually equal. We must reckon the pleasures of malevolence as well as those of benevolence."[151] Of his own pleasures--of the relative amounts of pleasure he gets from various sources--each man is the final judge. One man prefers "push-pin" to poetry, another poetry to "push-pin"; and neither has a right to call the other mistaken. If we are to aim at the greatest maximum pleasure, therefore, we must not strive for what are commonly called "high" pleasures rather than "low" pleasures, except as greater in intensity. If we must have a standard, the judgment of the φρόνιμος (~phronimos~) for which Mill contended must be superseded by the judgment of the average man. If pleasure is the only end, and satisfaction is simply another name for it, then it is plainly incorrect to say that "it is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied."[152] As has been urged from the evolutionist point of view, "there is no common measure of happiness to enable us to say that the more perfect being enjoys more of it than the less."[153] There seems one way only in which utilitarianism can bring its moral ideal into harmony with the upward tendency claimed for itself by evolutionist ethics--and that is, by maintaining that the pleasures incident to what are regarded as the higher functions are the pleasures which excel others in respect of "fecundity": they are the source of future pleasures, and are frequently inexclusive even in their present enjoyment. The difficulty in making this assertion is just that these "higher" pleasures are but slightly appreciated by the majority of men, and can hardly be said to be pleasures for them at all. But here the theory of evolution, whose adherents have been acting the part of the candid friend to utilitarianism, must come to its aid, and admit that human nature may be so modified in the future as to allow of the "highest" becoming also the "greatest" of pleasures. The argument in the mouth of the utilitarian is perhaps a somewhat arbitrary one, since it could be applied equally well to any class of pleasures. The notion of "higher," as applied either to conduct or to pleasure, has been accepted from current moral opinion. But the theory of evolution has set itself to explain this notion, and to develop a theory of morality in harmony with its own scientific positions, and
