The estimate of courage differs with respect to the two sexes, as does also that of chastity. The historical explanation is simple; courage was necessary in men in early social stages, to race-preservation; to women, on the other hand, has been given, from early times, a class of social functions not requiring courage. The estimate, once fixed, survives even when some of its early conditions disappear. The savage acquired his wife by knocking her down; to him the ideal feminine character must have included readiness to be knocked down, or at least unreadiness to strike again; and, as some of the forms of marriage recall the early system, so in the sentiments with which it is regarded there may still linger something of the early instinct associated with striking and being struck. The virtues of chastity and temperance occupy an intermediate position between the virtues of strength and the directly social virtues. Some of them are a part of the prudential, and others of the directly moral code. Temperance is primarily prudential, but the sexual and parental instincts concern the most intimate structure of society. Our instinctive classification of temperance as higher than courage has good reason; the classification of it as a personal virtue cannot be maintained. A man whose vice injures only himself in the first place, becomes incapable of benefiting others. As we condemn the man whose character is bad, whether external circumstances do, or do not, give him an opportunity of displaying it, so we object logically to the man who is destroying his social qualities, whether the immediate effect of his conduct tells upon himself or upon others. Another element, an instinctive disgust at sensuality, seems to precede judgment upon intemperance, with a strength not to be accounted for by a mere summing up of consequences. The human hog revolts us as the smell of the sty turns our stomach. The justification of the instinct is not that it implies a judgment of what is useful, but rather that it is a useful judgment. As men become more intellectual, sympathetic, and so forth, they gain fresh sensibilities, which are not simple judgments of consequences but as direct, imperative, and substantial, as any of the primitive sensibilities. To get rid of the sensibility you must lower the whole tone of the character. Asceticism, which has arisen chiefly at times of great indulgence, may have been of use if only as a demonstration of the possibility of conquering the prevailing passions. In a similar manner, we may think a great reformer, a Howard for example, admirable, though he neglects duties which must be performed in the ordinary case. We thus admit that the general moral code of benevolence prescribes different conduct according to a man's opportunities and talents.
