The contributions of Carl Jung to understanding of the human psyche are immense. Starting as Freud's most famous disciple, Jung soon broke away from his mentor to follow his own lines of investigation and discovery. Many of Jung's ideas are now considered fundamentals in the study of the mind, but other, more controversial theories dealing with the psychological relevance of alchemy, ESP, astrology, and occultism are only now being seriously examined. This condensation and summary of Jung's life and work by two eminent psychology professors is written with deep understanding and extraordinary clarity and is essential reading for anyone interested in the hidden depths of the mind.
