It is no longer possible to ignore the teachings of Friedrich Nietzsche, or to consider the trend of modern thought without giving the philosopher of the superman a prominent place in the list of thinkers who contributed to the store of present-day knowledge. His powerful and ruthless mind has had an influence on contemporary thought which even now, in the face of all the scholarly books of appreciation he has called forth, one is inclined to underestimate. No philosopher since Kant has left so undeniable an imprint on modern thought. Even Schopenhauer, whose influence coloured the greater part of Europe, made no such widespread impression. Nietzsche has penetrated into both England and America, two countries strangely impervious to rigorous philosophic ideals. Not only in ethics and literature do we find the moulding hand of Nietzsche at work, invigorating and solidifying; but in pedagogics and in art, in politics and religion, the influence of his doctrines is to be encountered.
