We must always hopefully and gladly remember that the great movements, doctrines, thoughts, which have affected the life of the world most deeply, are those which are most truly based upon the best and truest needs of humanity. We need never be afraid of a new theory or a new doctrine, because such things are never imposed upon an unwilling world, but owe their strength to the closeness with which they interpret the aims and wants of human beings. Still more hopeful is the knowledge which one gains from looking back at the history of the world, that no selfish, cruel, sensual, or wicked interpretation of life has ever established a vital hold upon men. The selfish and the cruel elements of humanity have never been able to band themselves together against the power of good for very long, for the simple reason that those who are selfish and evil have a natural suspicion of other selfish and evil people; and no combination of men can ever be based upon anything but mutual trust and affection. And thus good has always a power of combination, while evil is naturally solitary and disjunctive. Take such an attempt as that of Nietzsche to establish a new theory of life. His theory of the superman is simply this, that the future of the world was in the hands of strong, combative, powerful, predatory people. Those are the supermen, a natural aristocracy of force and unscrupulousness and vigour. But such individuals carry with them the seed of their own failure, because even if Nietzsche's view that the weak and broken elements of humanity were doomed to perish, and ought even to be helped to perish, were a true view, even if his supermen at last survived, they must ultimately be matched one against another in some monstrous and unflinching combat. Nietzsche held that the Christian doctrine of renunciation was but a translating into terms of a theory the discontent, the disappointment, the failure of the weak and diseased element of humanity, the slavish herd. He thought that Christianity was a glorification, a consecration of man's weakness and not of his strength. But he misjudged it wholly. It is based in reality upon the noble element in humanity, the power of love and trust and unselfishness which rises superior to the ills of life; and the force of Christianity lies in the fact that it reveals to men the greatness of which they are capable, and the fact that no squalor or wretchedness of circumstances can bind the thought of man, if it is set upon what is high and pure. The man or woman who sees the beauty of inner purity cannot ever be very deeply tainted by corruption either of body or of soul.
