A large number of hypnotists, including the author, has come to believe that hypnosis is a semantic problem in which words are the building blocks to success. Not just any words, but words which "ring a bell" or tap the experiential background of the subject. This is why "sleep" continues to be in the lexicon of the hypnotist even though hypnosis is the antithesis of sleep. The word is used because hypnosis superficially resembles sleep inasmuch as the eyes usually are closed, the body in a posture of complete relaxation. Actually, the mind is hyperacute. Pavlov, however, believed that there was an analogy between sleep and hypnosis in that each involved cerebral inhibition. Words, of course, would be of little use without the added effect of his conditioned reflexology. Probably the most widely held theory is that hypnosis is a transference phenomenon in which the prestige of the hypnotist and his relationship to the subject plays an important role. This theory is bolstered by the fact that all schools of psychotherapy yield approximately the same results even though the methods differ. This would logically indicate that the relationship between the therapist and the subject was the determining factor. The only trouble with this theory is that it does not explain self-hypnosis. On the other hand, we know that a strong interpersonal relationship is necessary for hypnosis. In the opening chapter of the book, I explained that hypnosis was a state of heightened suggestion in which the subject adopted an uncritical attitude, allowing him to accept suggestions and to take appropriate action. This is excellent as far as it goes, but it does not explain how suggestion works. This is the crux of the hypnotic dilemma and the answer is far from solved. Hypnotists are much like those who use electricity every day of their lives, but have no idea of the nature of electricity. It is enough for them to know it has been harnessed for their use. If there is one thing virtually certain about hypnosis it is that some parts of the brain are inhibited and other parts expanded by the process. Pin-point concentration is given as the reason for this selective procedure which narrows the horizon of the subject to what the hypnotist (or he, himself) is saying, screening out all other stimuli. But why is this high order of concentration so easy under hypnosis when Asians, notably the Chinese, have been trying for centuries to concentrate on one subject for as long as four or five seconds. We do not know the mechanics of this metamorphosis of an ordinary brain into an organ of concentrated power. According to Janet, this is accomplished through the formation of a group of unconscious memories and activities which takes over the usual stream-of-consciousness type of thinking. It is implied that the process may be atavistic.
