“The view I have just sketched of the relationships between the most general types—the forms of social life—and human nature is based upon two key ideas that might appear contradictory. The first notion holds that there exists a limited fund of problems and possibilities of human association. Each form of social life is defined by the way it responds to the problems and pursues the possibilities. The fact that the fund is limited makes comprehensive theory and universal comparison possible. This principle, however, seems incompatible with the other half of my thesisː that the forms of social life are constituents and re-creators, rather than just examples, of human nature. ¶ The way to reconcile these two equally important ideas is to conceive of human nature as an entity embodied in particular forms of social life, though never exhausted by them. Consequently, humanity can always transcend any one of the kinds of society that develop it in a certain direction. Nonetheless, human nature is known, indeed it exists, only through the historical types of social life.”
