Man gains enormous values from dealing with other men; living in a human society is his proper way of life-but only on certain conditions. Man is not a lone wolf and he is not a social animal. He is a contractual animal. He has to plan his life long-range, make his own choices, and deal with other men by voluntary agreement.
