Swiss psychiatrist Carl Jung created the psychological theory of archetypes and the collective unconscious. He advocated the scientific exploration of dreams, mythology, religion and art to understand the mind. Yet, unknown to millions of the people who have followed Jung’s work over the decades, Jung developed most of those ideas during a period of intense crisis and creativity between 1913 and 1918. He chronicled that voyage of self-discovery through words and images in what he called “The Red Book.”
