His truth is enclosed in a transcendental vacuum. Whether he had Galton's science of Eugenics in his mind when he modelled his Zarathustra we need not concern ourselves. His revaluation of moral values has not shaken morality to its centre. He challenged superficial conventional morality, but the ultimate pillars of faith still stand. He reminds us of William Blake when he writes: "The path to one's heaven ever leads through the voluptuousness of one's own hell." And his psychical resemblance to Pascal is striking. Both men were physically debilitated; their nervous systems, overwhelmed by the burdens they imposed upon them, made their days and nights a continuous agony. The Nietzschian philosophy may be negligible, but the psychological aspects of this singularly versatile, fascinating, and contradictory nature are not. His "Will to Power" in his own case resolves itself into the will to suffer. Compared to his, Schopenhauer's pessimism is the good-natured grumbling of a healthy, witty man, with a tremendous vital temperament. Nietzsche was delicate from youth. His experiences in the Franco-Prussian war harmed him. Headache, eye trouble, a weak stomach, coupled with his abuse of intellectual work, and, toward the last, indulgence in narcotics for insomnia, all coloured his philosophy. The personal bias was unescapable, and this bias favoured sickness, not health. Hence his frantic apotheosis of health, the dance and laughter, and his admiration for Bizet's Carmen. Hence his constant employment of joyful imagery, of bold defiance to the sober workaday world. His famous injunction: "Be hard!" was meant for his own unhappy soul, ever nearing, like Pascal's, the abyss of black melancholy.
