This bold and insightful book is the first to present the full work of highly influential British analyst, Herbert Rosenfeld. This Contemporary Introduction covers all of Rosenfeld’s significant publications between 1947 and 1987, as well as the later edited version of his clinical seminars in Italy. Hinshelwood deftly shows how Rosenfeld adopted Melanie Klein's theories on schizoid mechanisms and psychotic psychodynamics and applied them to working with patients experiencing psychosis. He traces the use of these ideas in an evolving understanding of psychotic states and other forms of disturbance. This book will be of interest to psychoanalysts and psychotherapists working with the development of Kleinian ideas. It will also be the perfect guide for students, mental health workers and psychotherapists who wish to know more about Rosenfeld’s approach to psychotic states.
