The great writers of the eighty years following the Restoration were consumed by a passion for observation--observation of the men and things that lay immediately around them. They may have seen but little; but what they did see, they grasped with surprising force and clearness. They may not have gone far beneath the surface; but, so far as they went, their work was a model of acuteness and precision. This was the secret of their power. To this may be traced their victory in the various tasks that they undertook. Hence, on the one hand, their success in painting the manners of their own day--a task from which, with some notable exceptions, the greatest of the Elizabethans had been apt to shrink, as from something alien to their genius; and, on the other hand, the range and keenness of their satire. Hence, finally, the originality of their work in criticism, and their new departure in philosophy. The energies of these men were diverse: but all sprang from the same root--from their invincible resolve to see and understand their world; to probe life, as they knew it, to the bottom. Thus the new turn given to criticism by Dryden was part of a far- reaching intellectual movement; a movement no less positive and self- contained than, in another aspect, it was negative and reactionary. And it is only when taken as part of that movement, as side by side with the philosophy of Locke and the satire of Swift or Pope, that its true meaning can be understood. Nor is it the least important or the least attractive of Dryden's qualities, as a critic, that both the positive and the negative elements of the prevailing tendency--both the determination to understand and the wish to bring all things under rule--should make themselves felt so strongly and, on the whole, so harmoniously in his Essays. No man could have felt more keenly the shortcomings of the Elizabethan writers. No man could have set greater store by that "art of writing easily" which was the chief pride of the Restoration poets. Yet no man has ever felt a juster admiration for the great writers of the opposite school; and no man has expressed his reverence for them in more glowing words. The highest eulogy that has yet been passed on Milton, the most discriminating but at the same time the most generous tribute that has ever been offered to Shakespeare--both these are to be found in Dryden. And they are to be found in company with a perception, at once reasoned and instinctive, of what criticism means, that was altogether new to English literature.
