The two minds being possessed of independent powers and functions, it follows as a necessary corollary that the subjective mind of an individual is as amenable to the control of his own objective mind as to the objective mind of another. This we find to be true in a thousand ways. For instance, it is well known that a person cannot be hypnotized against his will. As the hypnotic condition is usually induced by the suggestion of the operator, his failure is due to the contrary auto-suggestion of the subject. Again, if the subject submits to be hypnotized, but resolves beforehand that he will not submit to certain anticipated experiments, the experiments are sure to fail. One of the finest hypnotic subjects known to the writer would never allow himself to be placed in a position before a company which he would shrink from in his normal condition. He was possessed of a remarkable dignity of character, and was highly sensitive to ridicule; and this sensitiveness stepped in to his defence, and rendered abortive every attempt to cause him to place himself in a ridiculous attitude. Again, if a hypnotic subject is conscientiously opposed to the use of strong drink, no amount of persuasion on the part of the operator can induce him to violate his settled principles. And so on, through all the varying phases of hypnotic phenomena, auto-suggestion plays its subtle _rôle_, often confounding the operator by resistance where he expected passive obedience. It does not militate against the force of the rule that suggestion is the all-controlling power which moves the subjective mind. On the contrary, it confirms it, demonstrates its never-failing accuracy. It shows, however, that the stronger suggestion must always prevail. It demonstrates, moreover, that the hypnotic subject is not the passive, unreasoning, and irresponsible automaton which hypnotists, ancient and modern, have believed him to be. As this is one of the most important branches of the whole subject of psychological phenomena, it will be more fully treated when the various divisions of the subject to which the principle is applicable are reached. In the mean time, the student should not for a moment lose sight of this one fundamental fact, that the subjective mind is always amenable to the power of suggestion by the objective mind, either that of the individual himself, or that of another who has, for the time being, assumed control.
