For more than a hundred years, dissociative states, sometimes referred to as multiple personality disorder, have fascinated the public as well as scientists. The precise nature of this disorder is a controversial one, dividing clinicians, theorists, and researchers. Challenging the conventional wisdom on all sides, Robert Rieber ?s Bifurcation of the Self traces the clinical and social history of dissociation in a provocative examination of this widely debated phenomenon. At the core of this history is a trio of related evolutions ?hypnosis, concepts of identity, and dissociation ?beginning with nineteenth-century "hysterics" and culminating in the modern boom in Dissociative Identity Disorder (DID) diagnoses and the parallel rise in childhood abuse/repressed memory cases. Rieber does not argue the non-existence of DID; rather he asserts that it is a rare disorder exaggerated by dissociation advocates and exploited by the media. In doing so, he takes on some of the most difficult questions in the field: How crucial is memory to a person ?s identity? Can two or more autonomous personalities actually exist in the same body? If trauma causes dissociation, why aren ?t there more DID cases? Why are DID cases prevalent in some eras but not in others? Does dissociative disorder belong in the DSM? The book is rigorously illustrated with two centuries ? worth of famous cases including Christine Beauchamp, Ansel Bourne, Eve Black/Eve White, and most notably the woman known as "Sybil", whose story is covered in depth with newly revealed manuscripts. And Rieber reviews the current state of DID-related controversy, from the professionals who feel that the condition is underreported to those who consider it a form of malingering, so that readers may draw their own conclusions.
