When we say that we love a writer’s work, we are always stretching the truth: what we really mean is that we love about half of it. Sometimes rather more than half, sometimes rather less. The vast presence of Joyce relies pretty well entirely on “Ulysses,” with a little help from “Dubliners.” You could jettison Kafka’s three attempts at full-length fiction (unfinished by him, and unfinished by us) without muffling the impact of his seismic originality. George Eliot gave us one readable book, which turned out to be the central Anglophone novel. Every page of Dickens contains a paragraph to warm to and a paragraph to veer back from. Coleridge wrote a total of two major poems (and collaborated on a third). Milton consists of “Paradise Lost.” Even my favorite writer, William Shakespeare, who usually eludes all mortal limitations, succumbs to this law. Run your eye down the contents page and feel the slackness of your urge to reread the comedies (“As You Like It” is not as we like it); and who would voluntarily curl up with “King John” or “Henry VI, Part III”?
