The gregarious instinct may be the most elemental of the impulses which bind the group together, but it is reinforced by sympathies and sentiments growing out of common life, common work, common danger, common religion. The morality is already implicit, it needs only to become conscious. The standards are embodied in the old men or the gods; the rational good is in the inherited wisdom; the respect for sex, for property rights, and for the common good, is embodied in the system--but it is there. Nor are the union and control a wholly objective affair. "The corporate union was not a pretty religious fancy with which to please the mind, but was so truly felt that it formed an excellent basis from which the altruistic sentiment might start. Gross selfishness was curbed, and the turbulent passions were restrained by an impulse which the man felt welling up within him, instinctive and unbidden. Clannish camaraderie was thus of immense value to the native races."[18] LITERATURE The works of Hobhouse, Sumner, Westermarck contain copious references to the original sources.
