Carl Gustav Jung (1875-1961) Founded the analytical school of psychology and is responsible for bringing psychology into the twentieth century by developing a new theory of the unconscious.

'Indispensable for anyone who wants to understand something of Jung's psychology and metapsychology.' - Rosemary Gordon, Journal of Analytical Psychology'In this essay Jung reveals himself as the most original and widely informed psychologist of the twentieth century. With a dazzling combination of scholarship and clinical acumen, he addresses the problem of how we can know that the unconscious exists and how we can bring its contents to consciousness. With his characteristic emphasis on the primacy of psychic experience - 'the only reality which is given to us without a medium' - he carries his thinking beyond the psychodynamics of patients in analysis to examine the social and political catastrophes which follow when collective consciousness becomes dissociated from the collective unconscious. A basic text for anyone concerned with the spiritual life and psychic destiny of our species.' - Anthony Stevens'Next to Freud, no psychiatrist of today has advanced our insight into the nature of the psyche more than Jung has.' - Hermann Hesse
