All the while that Jean was listening to him, he was vaguely conscious that what gives literature its reality is the result of work accomplished by the human spirit, no matter what the material facts that may have stimulated it (a walk, a night of love, a social drama), of a sort of discovery in the world of the spirit, of the emotions, made by the human intelligence, so that the value of a book is never in the material presented by the writer, but in the nature of the operation he performs upon it.
