Gradually, then, she began to accept hypnotic suggestion, and would obey trivial orders given her while asleep, such as to sweep her room, etc.; then suggestions regarding her general behavior; then, in her hypnotic condition, she began to express regret for her past life and form resolutions of amendment, which she fully adhered to when she awoke. Two years later she was a nurse in one of the Paris hospitals, and her conduct was irreproachable. M. Voisin has followed up this case by others equally striking. Such is an imperfect sketch of the discoveries, experiments, and studies which have been made in the domain of human personality. It is merely a sketch, and certainly it is in no spirit of dogmatism that it is presented; but as a collection of facts relating to human nature and the constitution and action of the human mind, it is at least curious. It need not destroy our convictions regarding the essential unity of personality, but it must necessarily enlarge our conceptions of what _constitutes an individual_, and how under various circumstances that individual may act. From many points of view, and in relation to many departments of study and of human development--legal, moral, social, and educational--the subject presents important bearings; and, furthermore, in the solution of other psychological problems it will be found to possess the greatest possible interest and value. CHAPTER VII. AUTOMATISM--PLANCHETTE. Our ordinary actions, both physical and mental, are, for the most part, subject to our own voluntary guidance and choice. Of this, at least, we feel sure. We work, walk, talk, play upon an instrument, read a book, or write a letter, because we choose to do these things; and ordinarily they are done under the full guidance of our will and intelligence. Sometimes, however, actions are performed by us without our choice or guidance, and even without our consciousness, and such actions are called automatic. The thrifty housewife, perhaps also being of a literary turn of mind, may become deeply absorbed in an exciting novel, while at the same time her busy fingers, without thought or effort on her part, skilfully ply the knitting needles, or her well accustomed foot, with gentle motion, rocks the cradle. During an exciting conversation, or the absorbing consideration of some important subject or problem, the act of walking is performed without will or consciousness; the pianoforte player runs his scales and roulades with marvellous rapidity and precision while reading a book or carrying on an animated conversation. Such actions are performed automatically.
