The term "eighteenth century" in the vocabulary of the literary historian is commonly as vaguely used as the term Elizabethan. It borrows as much as forty years from the seventeenth and gives away ten to the nineteenth. The whole of the work of Dryden, whom we must count as the first of the "classic" school, was accomplished before chronologically it had begun. As a man and as an author he was very intimately related to his changing times; he adapted himself to them with a versatility as remarkable as that of the Vicar of Bray, and, it may be added, as simple-minded. He mourned in verse the death of Cromwell and the death of his successor, successively defended the theological positions of the Church of England and the Church of Rome, changed his religion and became Poet Laureate to James II., and acquiesced with perfect equanimity in the Revolution which brought in his successor. This instability of conviction, though it gave a handle to his opponents in controversy, does not appear to have caused any serious scandal or disgust among his contemporaries, and it has certainly had little effect on the judgment of later times. It has raised none of the reproaches which have been cast at the suspected apostasy of Wordsworth. Dryden had little interest in political or religious questions; his instinct, one must conceive, was to conform to the prevailing mode and to trouble himself no further about the matter. Defoe told the truth about him when he wrote that "Dryden might have been told his fate that, having his extraordinary genius slung and pitched upon a swivel, it would certainly turn round as fast as the times, and instruct him how to write elegies to Oliver Cromwell and King Charles the Second with all the coherence imaginable; how to write _Religio Laici_ and the _Hind and the Panther_ and yet be the same man, every day to change his principle, change his religion, change his coat, change his master, and yet never change his nature." He never changed his nature, he was as free from cynicism as a barrister who represents successively opposing parties in suits or politics; and when he wrote polemics in prose or verse he lent his talents as a barrister lends his for a fee. His one intellectual interest was in his art, and it is in his comments on his art--the essays and prefaces in the composition of which he amused the leisure left in the busy life of a dramatist and a poet of officialdom--that his most charming and delicate work is to be found. In a way they begin modern English prose; earlier writing furnishes no equal to their colloquial ease and the grace of their expression. And they contain some of the most acute criticism in our language--"classical" in its tone (_i.e._, with a preference for conformity) but with its respect for order and tradition always tempered by good sense and wit, and informed and guided throughout by a taste whose catholicity and sureness was unmatched in the England of his time.
