If "introversion" and "extraversion" are standard words in most people's vocabulary; if we now recognize a link between the contents of the individual psyche and the archetypal themes of myth and religion; if psychology has evolved into a genuine philosophy whose function is not only to cure mental illness but to find meaning in daily life, much of the credit belongs to Carl Gustav Jung. This comprehensive collection of writings by the epoch shaping Swiss psychoanalyst was edited by Joseph Campbell, himself the most famous of Jung's American followers. It comprises Jung's pioneering studies of the structure of the psyche -- including the works that introduced such notions as the collective unconscious, the Shadow, Anima and Animus -as well as inquiries into the psychology of spirituality and creativity, and Jung's influential "On Synchronicity," a paper whose implications extend from the I Ching to quantum physics. Campbell's introduction completes this compact volume, placing Jung's astonishingly wide-ranging oeuvre within the context of his life and times.
