It ultimately relates to the fundamental unit in human society, which is the family. Individualism is an expression of the selfish ego, a reflection of the radically autonomous person that leaves no room for the family and the corresponding virtues of society. My coauthor and I disagree with the conclusion that self-interest has been the deciding force in human affairs. Rather, we believe that altruism and the willingness to create a family have been the deciding force. The family provides citizens with a commitment to the future. The society that celebrates the individual over the family is a society in decay; it is overwhelmed by aggressive selfishness.
