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 make-up 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.
Such a generic feature is not readily eliminated, even under a process of selection so severe and protracted as that to which the traits here under discussion were subjected during the predatory and quasi-peaceable stages.

These peaceable traits are in great part alien to the methods and the animus of barbarian life.
