Much has been said of the dangers of hypnotism. There seems no doubt that very nervous persons are likely to be hurt by repeated recourse to the hypnotic condition. After a time they are likely to live most of their lives in a half-dreamy condition, in which initiative and spontaneous activity becomes more difficult than before. Where persons have been hypnotised by means of the flash of a bright object, or by some other special means, it sometimes happens that accidentally some similar object may send them into hypnotic trance. After a time, too, auto-hypnotism becomes possible, and much of the individual's waking time is occupied with efforts to keep himself from going into the hypnotic trance. These are, however, very extreme cases, likely to occur only in those who are not of strong mentality in the beginning. Unfortunately these are the individuals who are most likely to be made the subjects of repeated and prolonged hypnotic experimentation on the part of unscrupulous charlatans. For the great majority of those that are susceptible to the {131} hypnotic condition, there is very little danger. We now have on record the experiences of men who have seriously devoted many years to the study of hypnotic phenomena. There is entire agreement among these men that the possible dangers of hypnotism have been exaggerated. Indeed, it may be as well to say at once that most of what has been written with regard to the dangers of hypnotism has come from those who have least practical experience with the condition. Dr. Milne Bramwell, who, for a quarter of a century, has had a very extensive experience with hypnotism in its many phases, in his recent book on hypnotism, deliberately speaks of the "so-called dangers" of hypnotism. He has never seen any evil effects, though he has been practising hypnotism very freely on all kinds of patients for over twenty years. It is on the experience of such serious, disinterested observers that we must rely for our ultimate conclusions as to hypnotism, rather than on the claims of pseudo-experts who like to magnify their own powers, or on popular magazine articles, or still less the Sunday newspapers, the writers for which are mainly interested in producing a sensation. It seems probable that in the next few years hypnotism will occupy a less prominent place in popular interest than it has in the recent past. Interest in hypnotism runs in cycles, reaching a maximum about once a generation, and we are on the downward swing of the last wave of popular attention to this subject.
