What Psychologists Say: Jung's 1946 BBC Broadcast Talk "The Fight with the Shadow"
". . . the tide that rose in the unconscious after the first World War was reflected in individual dreams, in the form of collective, mythological symbols which expressed primitivity, violence, cruelty: in short, all the powers of darkness. When such symbols occur in a large number of individuals and are not understood, they begin to draw these individuals together as if by magnetic force, and thus a mob is formed. Its leader will be found in the individual who has the least resistance, the least sense of responsibility and, because of his inferiority, the greatest will to power. He will let loose everything that is ready to burst forth, and the mob will follow with the irresistible force of an avalanche” (220).
