"The amnesia made life very difficult; indeed, except for the help you gave me, I think it would have been impossible, and that I should have gone truly mad. How can I describe or give any clear idea of what it is to wake suddenly, as it were, and not to know the day of the week, the time of the day, or why one is in a given position? I would come to myself as A, perhaps on the street, with no idea of where I had been, or where I was going; fortunate if I found myself alone, for if I was carrying on a conversation I knew nothing of what it had been; fortunate, indeed, in that case, if I did not contradict something I had said, for, as B, my attitude toward all things was quite the opposite of that taken by A." Picture to yourself, my reader, how you would feel if, for a few hours almost every day, and sometimes for whole days at a stretch, you became virtually nonexistent, yet were made to realize, from what your friends told you, that a something or a somebody had taken possession of your organism, and was veritably acting in your place, and in a way utterly unlike your natural self. This was the state of affairs with Doctor Prince's luckless patient. In moods, tastes, points of view, habits of thought, and controlling ideas, her secondary personality was the very reverse of that which had been dominant when she first sought medical advice. There even were pronounced physical differences. Whenever she was in the A state, she was extremely neurasthenic, being afflicted now by one, now by another, of the multifarious functional disturbances that accompany neurasthenia, and being exhausted by the slightest effort. A walk of a few hundred yards would be almost enough to prostrate her. In the B state, on the contrary, she did not know the meaning of the word "pain," and was seemingly incapable of feeling fatigue. She would walk for miles without experiencing the slightest distress, was constantly on the go, and appeared to be in every way an exceptionally robust, healthy woman. Thus, physically, she was--as B--a decided improvement over herself as A. But with respect to psychical differences it was altogether another matter. In the A state, she was kind, considerate of others, self-sacrificing, animated by a keen sense of, and devotion to, duty; profoundly stirred by any tale of sorrow or suffering, and most conscientious--if anything, overconscientious, being tortured at times in an extraordinary degree by moral doubts. In the B state, she was selfish, thoughtless, and cold; one might almost say devoid of human feeling. Here is the way she herself has put it:
