CARL JUNG BELIEVED that to learn about the human experience, it was important to study dreams and mythology. History is the story of events that played out in civilization, but dreams and myths are expressions of the human heart. The themes and archetypes of our dreams and myths, Jung pointed out, transcend time and culture. They arise from unconscious instincts that governed our behavior long before civilization papered over and obscured them, and they therefore teach us about what it means to be human on the deepest level.
