The collective unconscious includes archetypes and symbols common to people across cultures. Jung developed this idea after studying different cultures and noting striking similarities in their patterns, myths, fairy tales, images, and religions. Traveling far afield from traditional science, Jung believed in astrology, spiritualism, telepathy, telekenesis, claivoyance, ESP and a number of other occult and paranormal phenomena.
In Deirdre Bair's recent Jung: A biography, we learn that Jung was "Agent 488", secretly working for the Office of Strategic Services, the predecessor to our CIA. In 1943, during World War II, Jung's job was to analyze the pychology of Nazi leaders for spy-recruiter Allen Dulles. In 1945, General Dwight Eisenhower, the supereme allied commander actually read Jung's ideas for persuading the German public to accept defeat Dulles thoroughly relied on Jung's pychological advice, including Jung's prediction that Hitler would kill himself. Later, Dulles said that "nobody will probably ever know how much Professor Jung contributed to the Allied cause during the war...[and that his work needed to remain] highly classified for the indefinite future."
