It is not to be inferred that criticism is thereby disdained and disregarded. The critical dicta of a Dryden or a Johnson, a Coleridge or a Hazlitt, and, more recently, an Arnold or a Pater, are valued and studied because they emphasize the vital elements essential to the proper appreciation of a literary product; and, moreover, because such critics, in transcending the limitations of their kind, establish higher and juster standards for the criticism of the future. On the other hand, the great majority of critical utterances must necessarily be ephemeral; they may exert considerable contemporary influence, but are usually forgotten long before the works that called them forth. Unless this criticism is more than a perfunctory examination of the merits and defects of the work under consideration, it cannot endure beyond its own brief day.
Several fruitless attempts have been made to reduce criticism to an exact science, which, quite disregarding the factor of personal taste, could refer all literature to a more or less fixed and arbitrary set of critical principles. The champions of this objective criticism point to the occasionally ludicrous divergence of the views expressed in criticism of certain poets or novelists, and insist that there is no occasion for such a bewildering difference of opinion. They seem to forget that the criticism which we esteem most highly at all times is the subjective criticism in which the personality of a competent and sincere critic is manifest. Literature, like music, painting and the other arts, has its own laws of technique--fundamental canons that must be observed in the successful pursuit of the art; but at a certain point difference of opinion is not only possible but profitable. The critics who would unite in condemning a thirteen-line sonnet or a ten-act tragedy could not be expected to agree on the relative merits of Milton's and Wordsworth's sonnets. Unanimity of opinion is as impossible and undesirable concerning the poetic achievement of Browning and Whitman as it is concerning the music of Brahms and Wagner, or the painting of Turner and Whistler. Great artists who have taken liberties with traditions and precedents have done much to prevent the critics from falling into a state of self-complacency over their scientific methods and formulas.
