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!

14. If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle. The Art Of War

“He alone knew something that even initiates didn’t know how easy it was to fast.”  A Hunger Artist

“Wherever you are , some will want to ask questions about your skin or your prayers. Beware of gratifying their instincts, my son, beware of bending before the multitude! Muslim, Jew or Christian, they must take you as you are, or lose you. When men's minds seem narrow to you, tell yourself that the land of God is broad; broad His hands and broad His heart. Never hesitate to go far away, beyond all seas, all frontiers, all countries, all beliefs.' Leo Africanus
