In translation from the French--after all France was the original proving ground With Charcot and Mesmer of this ""fact"" if somewhat imprecise science--this is a partly clinical, qualified if ultimately affirmative view of hypnosis. Or is it hypnotism? Even the correct term entertains doubt although the state is incontrovertible and it is not hysteria, sleep or paralysis. M. Dauven traces the earliest magnetizers, the period of disrepute which followed, the areas of related inquiry (Pavlov, for instance), and primarily its practice today (only 1 to 3% of all people are nonhypnotizable but induction is predicated on consent). Hypnosis can and has been used in medicine (primarily psychoanalytic and psychosomatic aspects thereof), anesthesia (sometimes it is definitely preferable), childbirth, and aspects of daily life (from sports to accelerating learning patterns). He also deals briefly with hypnosis as a collective as well as individual phenomenon. A serious and positive presentation.
