Later we shall have to show upon what grounds the community discriminates between acceptable and reprehensible facts, calling the former good and the latter bad. For the present it is enough to observe that Reason derives the laws, which it constantly impresses on man, from the opinion of the community. It can happen that Reason rejects the opinion of the community and forms a conclusion opposed to it. This revolt of individual morality against conventional morality is the great tragedy of man. It can only occur in the soul of a hero, for mediocre and insipid people always bow to the opinion of the majority. There is clearly imminent danger of making a mistake. Not seldom, however, the individual is right in his opposition to the community, and then the latter is fired by his example to examine its traditional dogmas and to correct or reject them. This is not the only, but it is the most common means by which Morality is developed and changed. Its progress demands martyrs. Strong personalities must be sacrificed to force a revision of moral values. Socrates has to swallow the draft of hemlock so that unfettered thought may acquire the right to doubt the legend of the gods. Jesus has to incur the dangerous anger of the Pharisees so that the adulteress may be treated with indulgence and human sympathy instead of being punished according to rigorous law. But the opposition of a self-willed, subjective Morality to the accepted moral law is always exceptional; the general rule is submission to the moral law. This is indeed a necessary preliminary to revolt against the moral law of the community, for it is only by means of a vigorous social education that man develops such a nicely balanced and keen sense of Good and Bad, that he cannot prevail upon himself to carry out generally approved actions which his own intelligence does not recognize as moral. He whose moral sense has not been intensified by strict discipline will never be assailed by doubt, as long as he follows in the footsteps of the multitude. Hence, as a rule, Reason exercises its control of the actions of man in conformity with the laws prescribed by the community. Before Morality develops into the practice of Good and the rejection of Bad it takes the form of consideration for the world at large, since it is the latter which has created the concepts of Good and Bad as well as the standard by which they are judged, and in order to avoid conflict with the community, and to maintain uninterrupted agreement with it, the individual exerts himself to persist in doing good and to refrain from doing evil.
