ye to them likewise," which lies at the foundation of morality. These social instincts, thus leading at last to the great rule of social morality, are developed very slowly. They are at first confined to the benefit of the same tribe, and they have no force in the relations of that tribe to the members of any other. To a savage it is a highly meritorious action to save the life of another member of his own tribe, and if he loses his own life in the effort it is so much the more meritorious. But he does not extend this idea of doing a good action to the members of a different tribe, and, whether his own tribe is or is not at war with the other tribe, he and his own community will think it no harm if he murders a member of that other tribe. But as the approach to civilization goes on--as man advances in intellectual power, and can trace the more remote consequences of his actions, and as he rejects baneful customs and superstitions, he begins to regard more and more not only the welfare but the happiness of his fellow-men. Habit, resulting from beneficial experiences, instruction and example, renders his sympathies more tender and widely diffused, until at last he extends them to men of all races, to the imbecile, maimed, and other useless members of society, and to the inferior animals. Thus the standard of morality rises higher and higher; but its origin is in the social instincts, which spring out of the love of approbation and the fear of disapprobation.[121] But morality comprehends also the self-regarding virtues, those which directly affect the individual, and which affect society but remotely and incidentally. How did the idea of these originate? There is a very wide difference between the morality of savages, in respect to the self-regarding virtues, and the morality of civilized nations. Among the former, the greatest intemperance, utter licentiousness, and unnatural crimes are very common. But as soon as marriage was introduced, whether monogamous or polygamous, jealousy led to the inculcation of female virtue; and this, being honored, spread to the unmarried females. Chastity, the hatred of indecency, temperance, and many other self-regarding virtues, originating first in the social instincts, have come to be highly prized by civilized nations as affecting, first, the welfare of the community, and, secondly, the welfare of the individual. This was the origin of the so-called "moral sense." It rejects the intuitive theory of morality, and bases its origin on the increasing perception of the advantage of certain conduct to the community and the individual.[122] SOPHEREUS. And in this origin of the social and the self-regarding virtues, which I understand you to say is the theory of Darwin, is the idea of a divine command to practice certain things, and to avoid doing certain other things, left out?
