This is that the only universal forms of behavior appear to be characteristic of people who must be termed abnormal. Such people are acting disappointing though this may be, according to the true nature of man because they are not under any artificial restraints. Cultured man is not natural man. Natural man does not naturally behave in a cultured way. Those who retain too great a measure of independence are necessarily confined to the asylum or the jail.
Culture is any artificial restraint of natural conduct.
This anthropological conclusion is remarkably close to the theological view of man as a sinner. And all that we know of history forces us to assent to his judgment. So deeply ingrained is this natural bent for destruction of himself and society that we have to conclude with Augustine that man was free to choose to do either good or evil until he fell, thereafter he had freedom only to choose the kind of evil he would do. As with the individual, so it is with the group. Its falsification of intention is so obvious that it becomes visible to the most short-sighted.
