This earlier variant is represented by the temperament which characterises the primitive phase of peaceable savagery. The circumstances of life and the ends of effort that prevailed before the advent of the barbarian culture, shaped human nature and fixed it as regards certain fundamental traits. 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.
