A reviewer, however (unless he publishes a collected edition and becomes a critic), has so far remained in the eyes of the public just a reviewer. In fiction we have been told (by the reviewers) of romancers and realists, sociologists and ethicists, naturalists and symbolists, objectivists and psychologists. Are there no adjectives, no brevet titles of literary distinction for the men and women who have made it possible to talk intelligently about modern fiction without reading it? My experience with reviewers has led me to classify them by temperament rather than by the theories they possess; and this is not so unscientific as it sounds, for theories usually spring from temperaments. No man whose eliminatory processes function perfectly is ever a pessimist, except under the compulsion of hard facts. No sluggish liver ever believes that joy of living is the prime quality to be sought in literary art. And by the same eternal principle, moody temperaments embrace one theory of criticism; cold, logical minds another. I identify my classes of reviewers by their habits, not their dogmas. But in order to clear the ground let me make first a larger distinction, into mythical reviewers, bad but useful reviewers, bad and not useful reviewers, and good reviewers. Like the nineteenth century preacher I will dispose of the false, dwell upon the wicked, and end (briefly) with that heaven of literary criticism where all the authors are happy and all the reviewers excellent. The reviewer I know best never, I profoundly believe, has existed, and I fear never will exist. He is the familiar figure of English novels--moderately young, a bachelor, with a just insufficient income in stocks. Oxford or Cambridge is his background, and his future is the death of a rich aunt or a handsome marriage. In the meantime, there is always a pile of books waiting in his chambers to be reviewed at "a guinea a page," when he has leisure, which is apparently only once or twice a week. The urban pastoral thus presented is one which Americans may well be envious of--_otium cum dignitate_. But I have never encountered this reviewer in London. I fear he exists only for the novelists, who created him in order to have a literary person with enough time on his hands to pursue the adventures required by the plot. Yet in so far as he is intended as a portrait of a critic, he stands as an ideal of the leisured view of books. There has been no leisured view of books in America since Thoreau, or Washington Irving. Even Poe was feverish. Our books are read on the subway, or after the theater, and so I fear it is in London--in London as it is.
