Multiple Man is a reissue of Crabtree's classical study of possession, multiple personality, and other dissociative states. The book deals both with normal human multiplicity and problematic forms. It is being republished at a time when the issues dealt with are every bit as relevant as when it first appeared.

"Adam Crabtree's Multiple Man is a classic in a field still in search of its own identity. His unifying perspective, in an area characterized by multiplicity and inconsistency, is based on considerable sophistication in psychology, the history of hypnosis and trance, where he has an especially thorough grounding, and psychotherapy. Crabtree has drawn, with a nicely detailed hand, the outline of a new psychophysics: a science of the forces that make for human integrity--or fragmentation. This book is a marvelous Odyssey into the wonders and terrors of human fragmentation and coming whole again."
--Stephen Larsen, Ph.D. is the author of The Mythic Imagination and with his wife Robin, A Fire in the Mind: The Life of Joseph Campbell.

"Adam Crabtree accomplishes the unusual in his groundbreaking book. He helps the reader come to grips with the fact that all is not as it seems--far from it. He explores the concepts of possession by the personalities of dead people, possession by living people, splintered off aspects of the core personality, as well as the conscious and subconscious minds, all within one individual. Crabtree's book will greatly reward the reader. I highly recommend it!"
--Edith Fiore, Ph.D. Author of The Unquiet Dead, You Have Been Here Before, and Encounters.

"Adam Crabtree is a pioneer in the field of multiple personality and he is to be commended for his scientific approach to this enigmatic disorder."
--From the Foreword by Chris Sizemore, subject of The Three Faces of Eve and author of The Final Face of Eve, I'm Eve, and A Mind of My Own.

"Adam Crabtree, drawing on the work of others and his own extensive clinical experience, has written a lucid description of our multiplicity. His courage in dealing with the unfashionable (but all-too-real to some people) phenomena of possession is commendable....He writes so clearly that I didn't know I was mastering difficult ideas as if I were reading an interesting novel!"
--Charles Tart, Ph.D., author of States of Consciousness and Waking Up.

"Multiple Man is a masterpiece at synthesizing a number of different concepts usually thought to be at odds with each other,...a milestone in the understanding of multiple personality and...evidence of possession, whatever that may mean to those involved."
--Ralph B. Allison, M.D., author of Mind in Many Pieces.

"Multiple Man is invaluable as a reference for case material. It surveys things that Freud did not mention, Jung only hinted at, and even modern writers have not yet explored. Crabtree's study of the multiplicity of human personality will force us to reconsider concepts of self, continuity, and identity."
--Joel Whitton, M.D., Ph.D., author of Life Between Life.

"Multiple Man is an original and masterful overview of the history and literature of possession and multiple personality, within both the psychological and occult traditions. In a measured and unsensational tone (the hallmark of Crabtree's writing, the literary equivalent of the calm and unfazed professional therapist), Multiple Man brings into a coherent context the dramatically outré phenomena of radically dissociated personality components and extraordinary spiritualistic occurrences, illustrating that these states are variations in degree of elements that are common-however moderately, latently or merely potentially-to all."
