The joy is in the surprise. It can be as small as a felicitous coupling of noun and adjective. Or a whole new scene, or the sudden emergence of an unplanned character who simply grows out of a phrase. Literary criticism, which is bound to pursue meaning, can never really encompass the fact that some things are on the page because they gave the writer pleasure. A writer whose morning is going well, whose sentences are forming well, is experiencing a calm and private joy. This joy itself then liberates a richness of thought that can prompt new surprises. Writers crave these moments, these sessions. If I may quote the second page of Atonement, this is the project’s highest point of fulfillment. Nothing else—cheerful launch party, packed readings, positive reviews—will come near it for satisfaction.
