. . . all the most convincing works of literature must possess an element of doubt. That is the calling card with which they delicately persuade us to open our doors to them; it is the proof that they do not intend to deceive us. And if this is true at the beginning of a novel, a story or a poem, it is even more noticeably true at the end. A question will always hover over the authoritative author’s conclusions, so that they are not merely conclusions, but also an opening out, a releasing of other possibilities.
