The theory and practice of hypnosis.
There are many theories about just what hypnosis is, but most investigators concede that whatever else it may be, it is at least a state of increased suggestibility. By limiting the field of consciousness and increasing concentration we do much to increase the force of suggestion. Thus, when suggestion is applied scientifically, it is possible to produce a state of hyper-suggestibility-which we know as hypnosis.
