The reason the novel is dying is because of Theory. Self-important establishment writers can write novels only with books of Theory stacked high beside them; Theories upon Theories about the novel. They add more Theory upon that. They phone university presses to assure themselves more books about Theory are on the way. "Ship them to me overnight!"
At one time, authors like Dickens just wrote the things. All the novelist needs is knowledge of the world and life and the ability to tell a story.
