Creative ideas, in my opinion, show their value in that, like keys, they help to “unlock” hitherto unintelligible connections of facts and thus enable man to penetrate deeper into the mystery of life. I am convinced that Jung’s ideas can serve in this way to find and interpret new facts in many fields of science (and also everyday life) simultaneously leading the individual to a more balanced, more ethical, and wider conscious outlook. If the reader should feel stimulated to work further on the investigation and assimilation of the unconscious-which always begins by working on oneself-the purpose of this introductory book would be fulfilled.
