If any man outside the pulpit were to ask himself what were the main conditions of happiness, the answer would certainly include health as the first, most essential, most sufficient condition. But the whole process of nature, upon the evolutionist doctrine, implies a correlation between the painful and the pernicious, and thus the elaboration of types in which this problem is solved by an ever-increasing efficiency and complexity of organization. Hence we may infer that the typical or ideal character, at any given stage of development, the organization which, as we may say, represents the true line of advance, corresponds to a maximum of vitality. It seems, again, that this typical form, as the healthiest, must represent not only the strongest type--that is, the type most capable of resisting unfavorable influences--but also the happiest type; for every deviation from it affords a strong presumption, not merely of liability to the destructive processes which are distinctly morbid, but also to a diminished efficiency under normal conditions. However, the typical man, though he is, on this theory, the virtuous man, is also much more than is generally understood by that name. Happiness is the reward offered, not for virtue alone, but for conformity to the law of nature, "Be strong." Beauty, strength, intellectual vigor, aesthetic sensibility, prudence, industry, and so forth, are all implied in the best type, and are, so far, conducive to happiness. If virtue be taken in the narrower sense as implying chiefly the negative quality of habitual abstinence from forbidden actions, there is no reason to suppose that it coincides with happiness. You can raise a presumption that moral excellence coincides closely with a happy nature only when you extend "moral" to include all admirable qualities. It is chiefly practical reasons which cause an attempted evasion of this conclusion; the practical moralist holds that the non-social qualities may be left to take care of themselves, but that stress must be laid upon the social qualities as the more important, in order to obtain them in society.
