A glimpse into Carl Jung's formative years, this book draws on previously unpublished details revealed to the author during interviews with Jung's son, Franz. It explores the period of Jung's life up to 1900, when he left medical school in Basel for Zurich to become a psychoanalyst.;Put into perspective are the historical influences and early experiences of Jung's life and their impact on his work. Jung himself attributed his theory of the collective unconscious to early childhood experiences, and to a particularly vivid dream of an underground phallus king, which haunted Jung throughout his life.
