Nor does partially developed industrialism fail to furnish a root. With social evolution, which implies transition from the life of wandering hunters to the life of settled peoples engaged in labor, and which therefore entails activities widely unlike those to which the aboriginal constitution is adapted, there comes an under-exercise of faculties for which the social state affords no scope, and an overtaxing of faculties required for the social state; the one implying denial of certain pleasures and the other submission to certain pains. Hence, along with that growth of population which makes the struggle for existence intense, bearing of pains and sacrifice of pleasures is daily necessitated. Now always and everywhere, there arises among men a theory conforming to their practice. The savage nature, originating the conception of a savage deity, evolves a theory of supernatural control sufficiently stringent and cruel to influence his conduct. With submission to despotic government severe enough in its restraints to keep in order barbarous natures, there grows up a theory of divine right to rule, and the duty of absolute submission. Where war is made the business of life by the existence of warlike neighbors, virtues which are required for war come to be regarded as supreme virtues; while, contrariwise, when industrialism has grown predominant, the violence and the deception which warriors glory in come to be held criminal. In like manner, then, there arises a tolerable adjustment of the actually accepted (not the nominally accepted) theory of right living, to living as it is daily carried on. If the life is one that necessitates habitual denial of pleasures and bearing of pains, there grows up an answering ethical system under which the receipt of pleasures is tacitly disapproved and the bearing of pains avowedly approved. The mischiefs entailed by pleasures in excess are dwelt on, while the benefits which normal pleasures bring are ignored; and the good results achieved by submission to pains are fully set forth, while the evils are overlooked. But while recognizing the desirableness of, and indeed the necessity for, systems of ethics adapted, like religious systems and political systems, to their respective times and places, we have here to regard the first as, like the others, transitional. We must infer that like a purer creed and a better government, a truer ethics belongs to a more advanced social state.
