The Dawn of Day · Friedrich Wilhelm Nietzsche
327.
A FABLE.—The Don Juan of knowledge—no philosopher or poet has yet succeeded in discovering him. He is wanting in love for the things he recognises, but he possesses wit, a lust for the hunting after knowledge, and the intrigues in connection with it, and he finds enjoyment in all these, even up to the highest and most distant stars of knowledge—until at last there is nothing left for him to pursue but the absolutely injurious side of knowledge, just as the drunkard who ends by drinking absinthe and aquafortis. That is why last of all he feels a longing for hell, for this is the final knowledge which seduces him. Perhaps even this would disappoint him, as all things do which one knows! and then he would have to stand still for all eternity, a victim to eternal deception, and transformed into his enemy, the Stony Guest, who longs for an evening meal of knowledge which will never more fall to his share! for the whole world of things will not have another mouthful left to offer to these hungry men. WHAT IDEALISTIC THEORIES DISCLOSE.—We are most certain to find idealistic theories among unscrupulously practical men; for such men stand in need of the lustre of these theories for the sake of their reputation. They adopt them instinctively without by any means feeling hypocritical in doing so—no more hypocritical than Englishmen with their Christianity and their Sabbath-keeping. On the other hand, contemplative natures who have to keep themselves on the guard against all kinds of fantasies and who dread to be reputed as enthusiasts, are only to be satisfied with hard realistic theories: they take possession of them under the same instinctive compulsion without thereby losing their honesty.
