The author's book combines a historical approach to the literature of Freud, Klein and the Post Kleinian development, with demonstrations of the central role of dream analysis. Students and practitioners of psychoanalysis and psychotherapy, educationalists, social scientists, doctors, and alll those who value the endeavour to enrich their work with imagination will find fine food for thought in these seminars, both in the survay of the literature, the case histories described, and in the concluding question and answer debates.
