Rediscovering Pierre Janet explores the legacy left by the pioneering French psychologist, philosopher and psychotherapist (1859–1947), from the relationship of between Janet and Freud, to the influence of his dissociation theory on contemporary psychotraumatology. Divided into three parts, the first section places Janetian psychological analysis and psychoanalysis in context with the foundational tenets of psychoanalysis, from Freud to relational theory, before the book explores Janet’s work on trauma and dissociation and its influence on contemporary thinking. Part three presents several contemporary psychotherapy approaches directly influenced by Janetian theory, including the treatment of posttraumatic stress disorder and dissociative identity disorder. Rediscovering Pierre Janet draws together eminent scholars from a variety of backgrounds, each of whom has developed Janetian constructs according to his or her own theoretical and clinical models. It provides an integrative approach that offers contemporary perspectives on Janet’s work, and will be of significant interest to practicing psychoanalysts, psychiatrists and psychotherapists, especially those treating trauma-related dissociative disorders, as well as researchers with an interest in psychological trauma.
