"How much reverence has a noble man for his enemies!--and such reverence is a bridge to love.--For he desires his enemy for himself, as his mark of distinction; he can endure no other enemy than one in whom there is nothing to despise and very much to honor! In contrast to this, picture "the enemy" as the man of ressentiment conceives him--and here precisely is his deed, his creation: he has conceived "the evil enemy," "the Evil One," and this in fact is his basic concept, from which he then evolves, as an afterthought and pendant, a "good one"--himself!"
