A man can write one book that can be great, but this doesn't make him a great writer-just the writer of a great book. . . I think a writer has to extend very widely, as well as plunge very deep, to be a great novelist.
Anthony BurgessThere is, in fact, not much point in writing a novel unless you can show the possibility of moral transformation, or an increase in wisdom, operating in your chief character or characters. Even trashy bestsellers show people changing. When a fictional work fails to show change, when it merely indicates that human character is set, stony, unregenerable, then you are out of field of the novel and into that of the fable or the allegory. - from the introduction of the 1986 Norton edition
