In his classic, provocative work, Dr. Carl Jung-one of psychiatry"s greatest minds-argues that the future depends on our ability to resist society"s mass movements. Only by understanding our unconscious inner nature-"the undiscovered self"-can we gain the self-knowledge that is antithetical to ideological fanaticism. But this requires facing the duality of the human psyche-the existence of good and evil in us all. In this seminal book, Jung compellingly argues that only then can we cope and resist the dangers posed by those in power.
