Booth argues, however, that pure fiction is virtually impossible and that a certain degree of rhetoric is necessary for successful literature. He sites examples of rhetoric used subtly in modern literature which directs the reader toward a clear comprehension of the work. The audience must be given clues through rhetoric in order to respond emotionally at the proper time and to the desired degree. In chapter five, Booth explores the modern critics theory of approaching literature without emotional involvement with the characters or the plot. Some degree of rhetoric is necessary not only to keep the audience involved but also to guide the reader to the intended moral judgements and values of the characters.
Booth devotes chapter six to expounding on the many possibilities of the role of the narrator.
Choice of narration is the author's most effective rhetorical device and merits extensive consideration in examining literature. In conclusion we agree with Booth that rhetoric is important and necessary for a thorough understanding of literature. Without the aid of rhetoric, readers may not fully understand the author's emotional intent and the meaning of the work is at risk of being misunderstood. Narration plays a key role in understanding the meaning of the work. Through narration the implied author allows the biological author to decide what information is useful and necessary to the work of fiction produced.
