It would, however, be a mistake to treat, as did Pope's first editor, the 'Essay on Criticism' as a methodical, elaborate, and systematic treatise. Pope, indeed, was flattered to have a scholar of such recognized authority as Warburton to interpret his works, and permitted him to print a commentary upon the 'Essay', which is quite as long and infinitely duller than the original. But the true nature of the poem is indicated by its title. It is not an 'Art of Poetry' such as Boileau composed, but an 'Essay'. And by the word "essay," Pope meant exactly what Bacon did,--a tentative sketch, a series of detached thoughts upon a subject, not a complete study or a methodical treatise. All that we know of Pope's method of study, habit of thought, and practice of composition goes to support this opinion. He read widely but desultorily; thought swiftly and brilliantly, but illogically and inconsistently; and composed in minute sections, on the backs of letters and scraps of waste paper, fragments which he afterward united, rather than blended, to make a complete poem, a mosaic, rather than a picture. Yet the 'Essay' is by no means the "collection of independent maxims tied together by the printer, but having no natural order," which De Quincey pronounced it to be. It falls naturally into three parts. The first deals with the rules derived by classic critics from the practice of great poets, and ever since of binding force both in the composition and in the criticism of poetry. The second analyzes with admirable sagacity the causes of faulty criticism as pride, imperfect learning, prejudice, and so on. The third part discusses the qualities which a true critic should possess, good taste, learning, modesty, frankness, and tact, and concludes with a brief sketch of the history of criticism from Aristotle to Walsh. This is the general outline of the poem, sufficient, I think, to show that it is not a mere bundle of poetic formulae. But within these broad limits the thought of the poem wanders freely, and is quite rambling, inconsistent, and illogical enough to show that Pope is not formulating an exact and definitely determined system of thought. Such indeed was, I fancy, hardly his purpose. It was rather to give clear, vivid, and convincing expression to certain ideas which were at that time generally accepted as orthodox in the realm of literary criticism. No better expression of these ideas can be found anywhere than in the 'Essay' itself, but a brief statement in simple prose of some of the most important may serve as a guide to the young student of the essay.
