A comparison of qualities, however, is one thing, and a comparison between different degrees of merit is quite another. The former is the essence of criticism; the latter, one of the most futile pastimes that can readily be imagined. That each man should have his own preferences is right enough. It would be a nerveless and unprofitable mind to which such preferences were unknown. More than that, some rough classification, some understanding with oneself as to what authors are to be reckoned supreme masters of their craft, is hardly to be avoided. The mere fact that the critic lays stress on certain writers and dismisses others with scant notice or none at all, implies that in some sense he has formed an estimate of their relative merits. But to drag this process from the background--if we ought not rather to say, from behind the scenes--to the very foot-lights, to publish it, to insist upon it, is as irrelevant as it would be for the historian-- and he, too, must make his own perspective--to explain why he has recorded some events and left others altogether unnoticed. All this is work for the dark room; it should leave no trace, or as little as may be, upon the finished picture. Criticism has suffered from few things so much as from its incurable habit of granting degrees in poetry with honours. "The highest art", it has been well said, "is the region of equals." It must be admitted that the Restoration critics had an immoderate passion for classing authors according to their supposed rank in the scale of literary desert. A glance at _The Battle of the Books_--a faint reflection of the quarrel between the ancients and the moderns--is enough to place this beyond dispute. Dryden himself is probably as guilty as any in this matter. His parallel between Juvenal and Horace, his comparison of Homer with Virgil, are largely of the nature of an attempt to show each poet to his proper place, to determine their due order of precedence in the House of Fame. In the early days of criticism this was perhaps to be expected. Men were feeling their way to the principles; and the shortest road might naturally seem to lie through a comparative table of the men. They were right in thinking that the first step was to ascertain what qualities, and what modes of treatment, give lasting pleasure in poetry; and, to do this, they could not but turn to compare the works of individual poets. But they were wrong in supposing that they could learn anything by striking the balance between the merits of one poet, as a sum total, and the merits of another.
