Some writers—John Barth, for instance—make a point of interrupting the fictional dream from time to time, or even denying the reader the chance to enter the fictional dream that his experience of fiction has led him to expect. We will briefly examine the purpose and value of such fiction later. For now, it is enough to say that such writers are not writing fiction at all, but something else, metafiction. They give the reader an experience that assumes the usual experience of fiction as its point of departure, and whatever effect their work may have depends on their conscious violation of the usual fictional effect. What interests us in their novels is that they are not novels but, instead, artistic comments on art.
