[17] The association of these two desires may surprise readers. It rests on a metaphysical ground, much of which will be more apparent when I have developed my theory of eroticism further. Time, like space, is conceived of as unlimited, and man, in his desire for freedom, in his efforts stimulated by his power of free will to transcend his limits, has the craving for unlimited time and unlimited space. The desire for travel is simply an expression of this restlessness, this fundamental chafing of the spirit against its bonds. But just as eternity is not prolonged time, but the negation of time, so however far a man wanders, he can extend his area but cannot abolish space. And so his efforts to transcend space must always be heroic failures: I shall show that his eroticism is a similar notable failure. As for Schopenhauer, he had just as little idea of the higher form of eroticism; his sexuality was of the gross order. This can be seen from the following: Schopenhauer’s countenance shows very little kindliness and a good deal of fierceness (a circumstance which must have caused him great sorrow. There is no exhibition of ethical sympathy if one is very sorry for oneself. The most sympathetic persons are those who, like Kant and Nietzsche, have no particle of self-pity). But it may be said with safety that only those who are most sympathetic are capable of a strong passion: those “who take no interest in things” are incapable of love. This does not imply that they have diabolical natures. They may, on the contrary, stand very high morally without knowing what their neighbours are thinking or doing, and without having a sense for other than sexual relations with women, as was the case with Schopenhauer. He was a man who knew only too well what the sexual impulse was, but he never was in love; if that were not so, the bias in his famous work, “The Metaphysics of Sexual Love,” would be inexplicable; in it the most important doctrine is that the unconscious goal of all love is nothing more than “the formation of the next generation.”
