Opinions of Experts on the "So Called" Dangers of Hypnotism In his book Clinical and Experimental Hypnosis, Dr. William S. Kroger,MD states, "Platonof, an associate of Pavlov, who used hypnosis over 50 years in over fifty thousand cases, reports as follows: "We have never observed any harmful influences on the patient which could be ascribed to the method of hypno-suggestion therapy, or any tendency toward the development of unstable personality, weakening of the will or pathological urge for hypnosis." Dr. David Cheek, MD, who has vast experience in the field, writes, "We can do more harm with ignorance of hypnotism than we can ever do by intelligently using hypnosis and suggestion contructively." Dr. Julius Grinker states, "The so-called dangers from hypnosis are imaginary. Although I have hypnotized many hundreds of patients, I have never seen any ill effects from its use." Pierre Janet, a student of Sigmund Freud who became an ardent practitioner of hypnosis, writes, "The only danger in hypnotism is that it is not dangerous enough." Psychologist Rafael Rhodes in his book, Therapy Through Hypnosis, writes, Hypnotism is absolutely safe. There is no known case on record of harmful results from its therapeutic use." Dr. Louie P. Thorpe, Professor Emeritus, Univ. of Southern California, in his book, The Psyshology of Mental Health, writes, "Hypnotism is a natural phenomenon, and there are no known deleterious effects from its use." Dr. M. Gerald Edelstein says, "The contraindications of hypnosis that they were taught during my psychiatric residency proved to be gross exaggerations."
