It is interesting to observe that the superstitious, the savage, the negro, and the soldier are excellent subjects for hypnotic purposes. Soldiers as experiments show, have a strong predisposition to hypnotic states. I was told by Professor Münsterberg that the hypnotic predisposition was strongly developed in the German soldier. M. Liebault experimented on ten hundred and twelve persons, and found only twenty-seven refractory. Berenheim remarks on this that “It is necessary to take into account the fact that M. Liebault operates chiefly upon the common people.” The great pressure exerted on the lower social strata, and especially on soldiers, the dull monotony of their life, the habit of strict obedience to command, predisposes them to social subconscious automatisms,--to the formation of mobs, clubs, unions, lodges, associations, parties, clans, sects, mobocracies. In all such organizations there is present the same servile spirit--the impersonal self and the gregarious fear instinct--the basis of subconscious, social somnambulism. Man is a social somnambulist, he lives, dreams, and obeys with his eyes open. Whenever the impulse of self-preservation gets a special grip on the gregarious individual, when he becomes wild with terror in the bosom of the herd, then he may be regarded as a psychopathic victim. The historian of the future will represent our age as dark, barbaric, savage, an age of the cruel Napoleonic wars, of commercial crises, financial panics, religious revivals, vicious, brutal, savage world wars,--mobs, crazes, plagues, social pests of all sorts and description.... A herd of sheep stand packed close together, looking stupidly into space.... Frighten them,--and if one begins to run, frantic with terror, the rest are sure to follow,--a stampede ensues, each sheep scrupulously reproduces the identical movements of the one in front of it. This susceptibility to imitation is but what we, in relation to man, term suggestibility, which consists in the impressing on the person of an idea, image, movement, however absurd and senseless, which the person in his hypnotized state reproduces like an automaton,--although he or she thinks it is done quite voluntarily. Suggestibility is natural to man as a social animal. Under specially favorable conditions this suggestibility which is always present in human beings may increase to an extraordinary degree, and the result is a stampede, a mob, an epidemic. It is sometimes claimed that somnambulic persons are asleep. Sleep and somnambulism have been identified. This is a misuse of words since there are a whole series of subconscious states in which not one symptom of sleep appears. _Extreme susceptibility to suggestions and mental automatisms are the chief traits of the subconscious._
