Fiction writers always confine themselves to narrative as distinct from discourse. Or, if they do write discourse, they develop a piece to serve as prologue to the narrative and then, after reaching the transitio, [48] quickly wind it up, evidently fearing a hopeless confusion. How can they conduct a philosophical discussion while poised for the fray? The author of this book is the only one who can display calm amid the panic and cool amid the heat. Into every tense passage of narrative he inserts a piece of leisurely discourse, posing and answering his questions in such an orderly fashion that the reader, far from finding it a distraction, is loath to see it end. When the author has finished his discourse and takes up the narration again, he is able to make it dovetail perfectly with what has gone before. A true master of the art! Ever since he invented this mode, he has been the only one capable of practicing it. Those who imitate his technique merely earn the reader's boredom.
