Nietzsche comments wryly on contemporary religious morality:
“One believes one must disapprove of Cesare Borgia; that is simply laughable. The church has excommunicated German emperors on account of their vices: as if a monk or priest had any right to join in a discussion about what a Frederick II may demand of himself. A Don Juan is sent to hell: that is very naive. Has it been noticed that in heaven all interesting men are missing? — Just a hint to the girls as to where they can best find their salvation.”
