III. Over the century that parts Dryden from Johnson it is not well to linger. During that time criticism must be said, on the whole, to have gone back rather than to have advanced. With some reservations to be noticed later, the critics of the eighteenth century are a depressing study. Their conception of the art they professed was barren; their judgments of men and things were lamentably narrow. The more valuable elements traceable in the work of Dryden--the comparative and the historical treatment--disappear or fall into the background. We are left with little but the futile exaltation of one poet at the expense of his rivals, or the still more futile insistence upon faults, shortcomings, and absurdities. The _Dunciad_, the most marked critical work of the period, may be defended on the ground that it _is_ the Dunciad; a war waged by genius upon the fool, the pedant, and the fribble. But, none the less, it had a disastrous influence upon English criticism and English taste. It gave sanction to the habit of indiscriminate abuse; it encouraged the purely personal treatment of critical discussions. Its effects may be traced on writers even of such force as Smollett; of such genius and natural kindliness as Goldsmith. But it was on Johnson that Pope's influence made itself most keenly felt. And _The Lives of the Poets_, though not written till the movement that gave it birth had spent its force, is the most complete and the most typical record of the tendencies that shaped English literature and gave the law to English taste from the Restoration to the French Revolution: a notable instance of the fact so often observed, and by some raised to the dignity of a general law, that both in philosophy and in art, the work of the critic does not commonly begin till the creative impulse of a given period is exhausted.
