A spirit of license makes a man refuse to commit himself to any standards. The right time is the way he sets his watch. The yardstick has the number of inches that he wills it to have. Liberty becomes license, and unbounded license leads to unbounded tyranny. When society reaches this stage, and there is no standard of right and wrong outside of the individual himself, then the individual is defenseless against the onslaught of cruder and more violent men who proclaim their own subjective sense of values. Once my idea of morality is just as good as your idea of morality, then the morality that is going to prevail is the morality that is stronger.
