How has a theory of man as a social being to be formulated if we are to do justice to his individuality, to the subtle ways in which his love and hate compete within his relations with others and to the anxieties and resistances he shows when he seeks to change himself? To answer this question is the task which the author sets himself. After assessing Freud’s basic principles, the author proceeds to make a uniquely comprehensive review of subsequent theoretical contributions to psychoanalysis with special emphasis on the work of Fairbairn and Melanie Klein. From a background of philosophy, theology and social studies, the author went on to take a personal psychoanalysis and to become a full time psychotherapist, and it is from this combination of wide knowledge and intensive work with people beset by conflicts in their relations with themselves and others that he evolves his views.
