Zarathustra, the first psychologist of the good, is—consequently—a friend of the evil. when a decadent type of man ascended to the rank of the highest type, this could only happen at the expense if its countertype, the type of man that is strong and sure of life. When the herd animal is irradiated by the glory of the purest virtue, the exceptional man must have been devaluated into evil. When the mendaciousness at any price monopolizes the word "truth" for its perspective, the really truthful man is bound to be branded with the worst names. Zarathustra leaves no doubt at this point: he says that it was his insight precisely into the good, the "best," that made him shudder at man in general; that it was from this aversion that he grew wings "to soar off into distant futures"; he does not conceal the fact that his type of man, a relatively superhuman type, is superhuman precisely in its relation to the good—that the good and the just would call his overman devil.
"You highest men whom my eyes have seen, this is my doubt about you and my secret laughter: I guess that you would call my overman—devil."
"What is great is so alien to your souls that the overman would be terrifying to you in his goodness." [Thus Spake Zarathustra, II, 43.]
It is here and nowhere else that one must make a start to comprehend what Zarathustra wants: this type of man that he conceives, conceives reality as it is, being strong enough to do so; this type is not estranged or removed from reality but is reality itself and exemplifies all that is terrible and questionable in it—only in that way can man attain greatness.
