I believe men capable of this self-discipline, once they recognize the need for it. I believe in this capacity because we see it achieved daily within narrow limits, as in a court of law, where judge and jury set aside their natural emotions and apply cold reason to the evidence. But we evade this responsibility to rise above emotion, instinct, passion, wherever collective conflicts like those of nationalism, race, class war, political partisanship are involved. In those fields we have seen, in our own generation, irrational passion rising to the point of hallucination and insanity. The German nation, educated and cultured beyond most, engaged in the wholesale massacre of millions of human beings because they belonged to the race which gave the world Jesus Christ.
