“There exists a subterranean world where pathological fantasies disguised as ideas are churned out by crooks and half-educated fanatics [notably the lower clergy] for the benefit of the ignorant and superstitious. There are times when this underworld emerges from the depths and suddenly fascinates, captures and dominates multitudes of usually sane and responsible people, who thereupon take leave of sanity and responsibility. And it occasionally happens that this underworld becomes a political power and changes the course of history.”
