And it is to these ancient, generic features that modern men are prone to take back in case of variation from the human nature of the hereditary present. The conditions under which men lived in the most primitive stages of associated life that can properly be called human, seem to have been of a peaceful kind; and the character -- the temperament and spiritual attitude of men under these early conditions or environment and institutions seems to have been of a peaceful and unaggressive, not to say an indolent, cast. For the immediate purpose this peaceable cultural stage may be taken to mark the initial phase of social development. So far as concerns the present argument, the dominant spiritual feature of this presumptive initial phase of culture seems to have been an unreflecting, unformulated sense of group solidarity, largely expressing itself in a complacent, but by no means strenuous, sympathy with all facility of human life, and an uneasy revulsion against apprehended inhibition or futility of life. Through its ubiquitous presence in the habits of thought of the ante-predatory savage man, this pervading but uneager sense of the generically useful seems to have exercised an appreciable constraining force upon his life and upon the manner of his habitual contact with other members of the group.
The traces of this initial, undifferentiated peaceable phase of culture seem faint and doubtful if we look merely to such categorical evidence of its existence as is afforded by usages and views in vogue within the historical present, whether in civilized or in rude communities; but less dubious evidence of its existence is to be found in psychological survivals, in the way of persistent and pervading traits of human character. These traits survive perhaps in an especial degree among those ethic elements which were crowded into the background during the predatory culture. Traits that were suited to the earlier habits of life then became relatively useless in the individual struggle for existence. And those elements of the population, or those ethnic groups, which were by temperament less fitted to the predatory life were repressed and pushed into the background.
