Pierre Janet's De l'Automatisme Psychologique, originally published in 1889, is one of the earliest and most important books written on the study of trauma and dissociation. Here it is made available in English for the first time, with a new foreword by Giuseppe Craparo and Onno van der Hart.

Published here in two volumes, this seminal work will be of great interest to researchers and students of psychoanalysis, philosophy and modernism, as well as psychotherapists and psychoanalysts working with clients who have experienced trauma.
