As nearly as I have been able to make out, Villiers de l'Isle-Adam had this same method of working. Once an idea had entered his mind--and it sometimes entered quite suddenly, in the course of a conversation most often, for he was a great talker, and profited by everything--this idea, which had come in timidly and silently through the side-door, soon installed itself as if it were at home, and invaded all the reserve spaces of the subconscious. Then, from time to time, it rose to the conscious level, and really obliged Villiers to act under its obsession. At such moments, no matter who was with him, he talked. He talked even when he was alone. Indeed he always talked as if he were alone, when he talked of his idea. I heard thus, fragmentary, several of his last stories, and once when we were seated in front of a café on the boulevard, I had the impression that I was listening to veritable mental wanderings in which this assertion recurred periodically: "There was a cock! There was!" It was only some months later, when _Le Chant du Coq_ appeared, that I understood. He spoke in a low voice, without addressing me. Yet his conscious aim, in thus turning over his ideas aloud, was to attempt to divine their effect upon a hearer. But, little by little, this purpose became obscured. It was the subconscious that was talking in his stead. He worked slowly. There exist five or six superimposed manuscripts of _L'Ève Future_, and the first differs so much from the last that Edison's name alone serves to link them together. It is often said of a man, who has written little, that he has done little work; but I am convinced that Villiers de l'lsle-Adam never stopped working an instant, even when asleep. In spite of the often absolute blockade that his ideas established about his attention, no mind ever worked more rapidly or was better gifted for conversation. He knew nothing of the twilight moments of awaking. After the fewest hours of sleep, he found himself, at a bound, in full possession of his verve and of his lucidity. Though, he was unquestionably the man of his books, it would, however, be possible to find in him the sketch of a dual personality, in which the conscious and unconscious so overlapped that it would be difficult to disentangle them. It would, on the other hand, be easy to write two lives of Mozart--one on the social individual, the other on the man in his second state, both perfectly legitimate.
