This eternal output of divine derision has never been so truly typified as by the character of Sam; he is a grotesque fountain which gushes the living waters for ever. Dickens is accused of exaggeration and he is often guilty of exaggeration; but here he does not exaggerate: he merely symbolises and sublimates like any other great artist. Sam Weller does not exaggerate the wit of the London street arab one atom more than Colonel Newcome, let us say, exaggerates the stateliness of an ordinary soldier and gentleman, or than Mr. Collins exaggerates the fatuity of a certain kind of country clergyman. And this breath from the boisterous brotherhood of the poor lent a special seriousness and smell of reality to the whole story. The unconscious follies of Winkle and Tupman are blown away like leaves before the solid and conscious folly of Sam Weller. Moreover, the relations between Pickwick and his servant Sam are in some ways new and valuable in literature. Many comic writers had described the clever rascal and his ridiculous dupe; but here, in a fresh and very human atmosphere, we have a clever servant who was not a rascal and a dupe who was not ridiculous. Sam Weller stands in some ways for a cheerful knowledge of the world; Mr. Pickwick stands for a still more cheerful ignorance of the world. And Dickens responded to a profound human sentiment (the sentiment that has made saints and the sanctity of children) when he made the gentler and less-travelled type--the type which moderates and controls. Knowledge and innocence are both excellent things, and they are both very funny. But it is right that knowledge should be the servant and innocence the master.
