(2) In all the later stages of animal evolution, however, moral development is largely conscious, or semi-conscious. Besides our inner inheritance of altered brain-paths there is a social inheritance of habits which each generation adopts by imitation of its predecessors. Without any deliberate intention, the young of every species imitate their parents, and then the older members of the flock or herd. "Suggestion" is said by some to be the chief means of moralization; we are brave or industrious because we see others practicing these virtues and naturally do as they do. At any rate, whichever are more important, the inherited tendencies or those acquired by contagion, both of these factors play a large part in the development of the individual's morals. (3) The third method of moral development is that which we call "learning by experience." The pain or dissatisfaction which a wrong impulse brings in its train, the satisfaction which follows a moral act, are remembered, and recur with the recurrence of a similar situation, becoming perhaps the decisive factors in steering the animal or man toward his true welfare. Many animals quite low in the organic scale learn by experience; and though of course the degree of consciousness that accompanies these readjustments varies enormously, this method of moralization may be said to be always, like the preceding, a more or less conscious process. Learning by experience is subject, of course, to many mistaken judgments; the fallacy of post hoc propter hoc leads many learners to avoid perfectly innocent acts as supposedly involving some evil result with which they were once by chance connected; and the true causes of the evils are often overlooked. Even when dimly conscious readjustments become highly conscious deliberation, the results of that deliberation may be less forwarding morally than the unconscious and merciless grinding of natural selection. More and more, of course, as men grew in power of reflection, did they consciously shape their morals; and this intelligent selection, which has as yet played a comparatively small role, is bound, as men become more and more rational, to supersede in importance the other factors in moral evolution. But in the later phases of evolution all three of these processes blend together; and it would be impossible for the keenest analyst to tell how much of his conduct was determined in each of these ways.
