For the fault in “Pickwick” (if it be a fault) is a change, not in the hero but in the whole atmosphere. The point is not that Pickwick turns into a different kind of man; it is that “The Pickwick Papers” turns into a different kind of book. And however artistic both parts may be, this combination must, in strict art, be called inartistic. A man is quite artistically justified in writing a tale in which a man as cowardly as Bob Acres becomes a man as brave as Hector. But a man is not artistically justified in writing a tale which begins in the style of “The Rivals” and ends in the style of the “Iliad.” In other words, we do not mind the hero changing in the course of a book; but we are not prepared for the author changing in the course of the book. And the author did change in the course of this book. He made, in the midst of this book a great discovery, which was the discovery of his destiny, or, what is more important, of his duty. That discovery turned him from the author of “Sketches by Boz” to the author of “David Copperfield.” And that discovery constituted the thing of which I have spoken--the outstanding and arresting original feature in “The Pickwick Papers.” “Pickwick,” I have said, is a romance of adventure, and Samuel Pickwick is the romantic adventurer. So much is indeed obvious. But the strange and stirring discovery which Dickens made was this--that having chosen a fat old man of the middle classes as a good thing of which to make a butt, he found that a fat old man of the middle classes is the very best thing of which to make a romantic adventurer. “Pickwick” is supremely original in that it is the adventures of an old man. It is a fairy tale in which the victor is not the youngest of the three brothers, but one of the oldest of their uncles. The result is both noble and new and true. There is nothing which so much needs simplicity as adventure. And there is no one who so much possesses simplicity as an honest and elderly man of business. For romance he is better than a troop of young troubadours; for the swaggering young fellow anticipates his adventures, just as he anticipates his income. Hence, both the adventures and the income, when he comes up to them, are not there. But a man in late middle-age has grown used to the plain necessities, and his first holiday is a second youth. A good man, as Thackeray said with such thorough and searching truth, grows simpler as he grows older. Samuel Pickwick in his youth was probably an insufferable young coxcomb. He knew then, or thought he knew, all about the confidence tricks of swindlers like Jingle. He knew then, or thought he knew, all about the amatory designs of sly ladies like Mrs. Bardell. But years and real life have relieved him of this idle and evil knowledge. He has had the high good luck in losing the follies of youth, to lose the wisdom of youth also. Dickens has caught, in a manner at once wild and convincing, this queer innocence of the afternoon of life.
