Ver. 652. _Who conquered nature, &c._] By this we must not understand physical nature, but moral. The force of the observation consists in giving it this sense. The poet not only uses the word nature, for human nature, throughout this poem; but also, where in the beginning of it, he lays down the principles of the arts he treats of, he makes the knowledge of human nature the foundation of all criticism and poetry. Nor is the observation less true than apposite. For Aristotle's natural inquiries were superficial and ill made, though extensive; but his logical and moral works are supremely excellent. In his moral, he has unfolded the human mind, and laid open all the recesses of the heart and understanding; and in his logical, he has not only conquered nature, but by his categories, has kept her in tenfold chains; not as dulness kept the muses in the Dunciad, to silence them; but as Aristæus held Proteus in Virgil, to deliver oracles. Ver. 665. _See Dionysius, &c._] In the first of these lines, on which the other depends, the peculiar excellence of this critic, and indeed the most material and useful part of a critic's office, is touched upon, who, like the refiner, purifies the rich ore of an original writer; for such a one busied in creating, often neglects to separate and refine the mass, pouring out his riches rather in bullion than in sterling. Ver. 667. _Fancy and art, &c._] "The chief merit of Petronius," says an objector,[302] "is that of telling a story with grace and ease." But the poet is not here speaking, nor was it his purpose to speak, of the chief merit of Petronius, but of his merit as a critic, which consisted, he tells us, in softening the art of a scholar with the ease of a courtier, and whoever reads and understands the critical part of his abominable story-telling will see that the poet has given his true character as a critic, which was the only thing he had to do with. Ver. 693. _At length Erasmus, &c._] Nothing can be more artful than the application of this example, or more happy than the turn of the compliment. To throw glory quite round the character of this admirable person, he makes it to be (as in fact it really was) by his assistance chiefly, that Leo was enabled to restore letters and the fine arts in his pontificate. Ver. 694. _The glory of the priesthood and the shame!_] Our author elsewhere lets us know what he esteems to be the glory of the priesthood as well as of a christian in general, where comparing himself to Erasmus, he says, In moderation placing all my glory, and consequently what he regards as the shame of it. The whole of this character belonged eminently and almost solely to Erasmus: for the other reformers, such as Luther, Calvin, and their followers, understood so little in what true christian liberty consisted, that they carried with them, into the reformed churches, that very spirit of persecution, which had driven them from the church of Rome.
