Personal Responsibility.--For ordinary normal individuals, this question of secondary personality has scant interest. Normal persons go about their work realizing that what they want to do, they may do, and what they do not want to do they can keep from doing, unless some contrary _physical_ force intervenes. There are many metaphysical arguments for free will, but none of them is so convincing as the observation that every sane man, with regard to his own actions, has the power to choose between two things that attract him. He may be much drawn to one thing, yet choose another. He may allow himself to be ruled by baser motives; he may sternly follow the {149} dictates of reason, or he may do neither and hold himself inactive. In any case, he realizes his power to choose. While this power may be impaired by many external conditions, his consciousness of its actuality makes him appreciate his responsibility. He realizes that punishment for wrong done is not only a part of the law, but it is also a proper vindication of that consciousness of free will which all men have, and which does not deceive them. The question has been obscured by much talk, but the reality is there, and the common-sense of mankind has proclaimed its truth. All our laws are founded on it. Without it punishment as meted out is an awful injustice and crime is a misnomer. Hysterical Phenomena.--Most of the cases of secondary personality that have been discussed at greatest length have been in persons who were as desirous of attracting attention, and as pleased over being the subject of special study as were the hysterical patients who used to delight in investigation two generations ago. That most of the phenomena of so-called dual personalities are mainly hysterical seems now to be clear. In a few cases, where the patient has found that the existence of a double personality was of special interest, a definite tendency to the formation of further personalities has been noted. Some triple personalities have been discussed and, in a few cases, a group of personalities, even up to five or more, began to assert themselves. This _reductio ad absurdum_, of the hypothesis of supernumerary personality has revealed the real hysteric character of the phenomena.
