"They're aphasias. An individual forgets his name, and he picks, or is given, another, if he happens to wander among strangers. He forgets much of his past experience; the second personality is merely what's left of the first—sort of a vestige of his normal character. There isn't any such thing as a dual personality in the sense of two distinct characters living in one body."
"Isn't there?" queried the girl musingly. "Could the second personality have qualities that the first one lacked?"
"Not any more than it could have an extra finger! The second is merely a split off the first, a forgetfulness, a loss of memory. It couldn't have more qualities than the whole, or normal, character; it must have fewer."
"Isn't that just too interesting!" said Pat in a bantering tone. "All right, Dr. Carl. It's your turn."
"Then what's the reason for all this curiosity about perversions and aphasias? What's happened to your genius now?"
"Oh, I'm thinking of taking up the study of psychiatry," replied the girl cheerfully.
"Aren't you going to answer me seriously?"
"No."
"Then what's the use of my asking questions?"
"I know the right answer to that one. None!"
