"Man represses the irrational passions of destructiveness, hate, envy, revenge; he worships power, money, the sovereign state, the nation; while he pays lip service to the teachings of the great spiritual leaders of the human race, those of Buddha, the prophets, Socrates, Jesus, Mohammed-he has transformed these teachings into a jungle of superstition and idol-worship. How can mankind save itself from destroying itself by this discrepancy between intellectual-technical overmaturity and emotional backwardness?"
