スイスの精神科医で心理学者、カール＝グスタフ・ユング（1875-1961年）の分析心理学（ユング心理学）を取り上げます。その基本概念に触れ、神話、宗教、魔術、共時性、性別による心理の違いといった異なるテーマに対する分析を解説します。さらに人生の節目や心理学的類型、夢分析、ユング派精神分析などの実践についても検討します。
　　　

• Jung's ideas are of considerable general interest - in particular his theories of the unconscious, and his views on the interpretation of dreams - which gave rise to a whole branch of psychotherapy, Jungian analysis
• Anthony Stevens is himself a distinguished Jungian analyst and psychiatrist, as well as a prolific writer on Jungian themes

   
Though he was a prolific writer and an original thinker of vast erudition, Jung lacked a gift for clear exposition and his ideas are less widely appreciated than they deserve. 

In this concise introduction, Anthony Stevens explains clearly the basic concepts of Jungian psychology: the collective unconscious, complex, archetype, shadow, persona, anima, animus, and the individuation of the Self. He examines Jung's views on such disparate subjects as myth, religion, alchemy, `sychronicity', and the psychology of gender differences, and he devotes separate chapters to the stages of life, Jung's theory of psychological types, the interpretation of dreams, the practice of Jungian analysis, and to the unjust allegation that Jung was a Nazi sympathizer. Finally, he argues that Jung's visionary powers and profound spirituality have helped many to find an alternative set of values to the arid materialism prevailing in Western society.
