Such experiments of the psychological laboratory can be varied a thousandfold, and it might not be unwise to introduce them into many practical fields. Everybody knows for instance how much may depend upon the suggestibility of the witness in court. The suggestible witness believes himself to have seen and heard what the lawyer suggests. The memory picture which such a witness has in mind offers, of course, much less resistance to the opposite action and attitude and belief than the immediate impression. If I show the witness a colored picture of a room and close the book and ask him whether there were three or four chairs in the picture and whether the curtain was green or red, the suggestible man will decide for one or the other proposition, even if there were only two chairs and a blue curtain. The perception would have resisted the suggestion, the fading memory image cannot resist it. Thus suggestibility is really a practical factor in every walk of life. And it is in the highest interests of psychotherapy that this intimate connection between suggestion and ordinary talk and intercourse, between suggestion and ordinary choice of motives, between suggestion and attention be steadily kept in view and that suggestion is not transformed into a kind of mysterious agency. To be sure, the importance of suggestion for psychotherapy is not confined to these suggestive processes of daily life. They play a role there, as we shall see, and we shall claim that even the mere presence of the physician may have its suggestive power and so may every remedy which he applies. But no doubt many of his suggestive effects depend on a power which far transcends the suggestions of our daily life. Yet the psychologist must insist again that no new principle is involved, that even in the strongest forms of suggestion, in hypnotism, nothing depends upon any special influence emanating from the mind of the hypnotizer or upon any special power flowing over from brain to brain; but that everything results from the change of equilibrium in the psychomotor processes of the hypnotized, and thus upon the interplay of his own mental functions. All that is needed is a higher degree of suggestibility than is found in the normal life. In a more suggestible mind even the direct sense impressions may be overwhelmed by the proposition for an untrue belief and the strongest desires may yield to the new propositions of action. This library may then become a garden where the hypnotized person picks flowers from the floor, and the wise man stands on one leg and repeats the alphabet, if the hypnotizer asks him to do so. Let us consider at first this extreme case. By a few manipulations I have brought a man into a deep hypnotic state. He is now unable to resist any suggestion, either suggestion of impulse or suggestion of belief, and as every one of the hypnotic phenomena can be explained in this way, we may claim that the hypnotic state is in its
