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.
On the transition to the predatory culture the character of the struggle for existence changed in some degree from a struggle of the group against a non-human environment to a struggle against a human environment. This change was accompanied by an increasing antagonism and consciousness of antagonism between the individual members of the group. The conditions of success within the group, as well as the conditions of the survival of the group, changed in some measure; and the dominant spiritual attitude for the group gradually changed, and brought a different range of aptitudes and propensities into the position of legitimate dominance in the accepted scheme of life. Among these archaic traits that are to be regarded as survivals from the peaceable cultural phase, are that instinct of race solidarity which we call conscience, including the sense of truthfulness and equity, and the instinct of workmanship, in its naive, non-invidious expression.
Under the guidance of the later biological and psychological science, human nature will have to be restated in terms of habit; and in the restatement, this, in outline, appears to be the only assignable place and ground of these traits. These habits of life are of too pervading a character to be ascribed to the influence of a late or brief discipline. The ease with which they are temporarily overborne by the special exigencies of recent and modern life argues that these habits are the surviving effects of a discipline of extremely ancient date, from the teachings of which men have frequently been constrained to depart in detail under the altered circumstances of a later time; and the almost ubiquitous fashion in which they assert themselves whenever the pressure of special exigencies is relieved, argues that the process by which the traits were fixed and incorporated into the spiritual makeup of the type must have lasted for a relatively very long time and without serious intermission. The point is not seriously affected by any question as to whether it was a process of habituation in the old-fashioned sense of the word or a process of selective adaptation of the race.
The character and exigencies of life, under that regime of status and of individual and class antithesis which covers the entire interval from the beginning of predatory culture to the present, argue that the traits of temperament here under discussion could scarcely have arisen and acquired fixity during that interval. It is entirely probable that these traits have come down from an earlier method of life, and have survived through the interval of predatory and quasi-peaceable culture in a condition of incipient, or at least imminent, desuetude, rather than that they have been brought out and fixed by this later culture. They appear to be hereditary characteristics of the race, and to have persisted in spite of the altered requirements of success under the predatory and the later pecuniary stages of culture. They seem to have persisted by force of the tenacity of transmission that belongs to an hereditary trait that is present in some degree in every member of the species, and which therefore rests on a broad basis of race continuity.
