Belief is the systematic taking of unanalysed words much too seriously. Paul’s words, Mohammed’s words, Marx’s words, Hitler’s words—people take them too seriously, and what happens? What happens is the senseless ambivalence of history—sadism versus duty, or (incomparably worse) sadism as duty; devotion counterbalanced by organized paranoia; sisters of charity selflessly tending the victims of their own church’s inquisitors and crusaders.
