All his natural and all his acquired powers fitted him to found a good critical school of poetry. Indeed he carried his reforms too far for his age. After his death our literature retrograded; and a century was necessary to bring it back to the point at which he left it. The general soundness and healthfulness of his mental constitution, his information, of vast superficies, though of small volume, his wit scarcely inferior to that of the most distinguished followers of Donne, his eloquence, grave, deliberate, and commanding, could not save him from disgraceful failure as a rival of Shakspeare, but raised him far above the level of Boileau. His command of language was immense. With him died the secret of the old poetical diction of England,--the art of producing rich effects by familiar words. In the following century it was as completely lost as the Gothic method of painting glass, and was but poorly supplied by the laborious and tesselated imitations of Mason and Gray. On the other hand, he was the first writer under whose skilful management the scientific vocabulary fell into natural and pleasing verse. In this department, he succeeded as completely as his contemporary Gibbons succeeded in the similar enterprise of carving the most delicate flowers from heart of oak. The toughest and most knotty parts of language became ductile at his touch. His versification, in the same manner, while it gave the first model of that neatness and precision which the following generation esteemed so highly, exhibited at the same time, the last examples of nobleness, freedom, variety of pause, and cadence. His tragedies in rhyme, however worthless in themselves, had at least served the purpose of nonsense-verses; they had taught him all the arts of melody which the heroic couplet admits. For bombast, his prevailing vice, his new subjects gave little opportunity; his better taste gradually discarded it. He possessed, as we have said, in a pre-eminent degree the power of reasoning in verse; and this power was now peculiarly useful to him. His logic is by no means uniformly sound. On points of criticism, he always reasons ingeniously; and when he is disposed to be honest, correctly. But the theological and political questions which he undertook to treat in verse were precisely those which he understood least. His arguments, therefore, are often worthless. But the manner in which they are stated is beyond all praise. The style is transparent. The topics follow each other in the happiest order. The objections are drawn up in such a manner that the whole fire of the reply may be brought to bear on them. The circumlocutions which are substituted for technical phrases are clear, neat, and exact. The illustrations at once adorn and elucidate the reasoning. The sparkling epigrams of Cowley, and the simple garrulity of the burlesque poets of Italy, are alternately employed, in the happiest manner, to give effect to what is obvious or clearness to what is obscure.
