““It is eminently reasonable that men should seek to associate with those who share their convictions and values. It is impossible to deal or even to communicate with men whose ideas are fundamentally opposed to one’s own (and one should be free not to deal with them). All proper associations are formed or joined by individual choice and on conscious, intellectual grounds (philosophical, political, professional, etc.)—not by the physiological or geographical accident of birth, and not on the ground of tradition. When men are united by ideas, i.e., by explicit principles, there is no room for favors, whims, or arbitrary power: the principles serve as an objective criterion for determining actions and for judging men, whether leaders or members.””
