versify it on the back of an envelope. Nor must we forget, like some of his commentators, that after all Pope was an exceedingly clever man. His rapidly perceptive mind was fully qualified to imbibe the crude versions of philosophic theories which float upon the surface of ordinary talk, and are not always so inferior to their prototypes in philosophic qualities, as philosophers would have us believe. He could by snatches seize with admirable quickness the general spirit of a doctrine, though unable to sustain himself at a high intellectual level for any length of time. He was ready with abundance of poetical illustrations, not, perhaps, very closely adapted to the logic, but capable of being elaborated into effective passages; and, finally, Pope had always a certain number of more or less appropriate commonplaces or renderings into verse of some passages which had struck him in Pascal, or Rochefoucauld, or Bacon, all of them favourite authors, and which could be wrought into the structure at a slight cost of coherence. By such means he could put together a poem, which was certainly not an organic whole, but which might contain many striking sayings and passages of great rhetorical effect.
The logical framework was, we may guess, supplied mainly by Bolingbroke. Bathurst told Warton that Bolingbroke had given Pope the essay in prose, and that Pope had only turned it into verse; and Mallet—a friend of both— is said to have seen the very manuscript from which Pope worked. Johnson, on hearing this from Boswell, remarked that it must be an overstatement.
