Podsnap is all Mr. Osborne's opinions separated from Mr. Osborne and turned into a character. In short the satirist is more purely philosophical than the novelist. The novelist may be only an observer; the satirist must be a thinker. He must be a thinker, he must be a philosophical thinker for this simple reason; that he exercises his philosophical thought in deciding what part of his subject he is to satirise. You may have the dullest possible intelligence and be a portrait painter; but a man must have a serious intellect in order to be a caricaturist. He has to select what thing he will caricature. True satire is always of this intellectual kind; true satire is always, so to speak, a variation or fantasia upon the air of pure logic. The satirist is the man who carries men's enthusiasm further than they carry it themselves. He outstrips the most extravagant fanatic. He is years ahead of the most audacious prophet. He sees where men's detached intellect will eventually lead them, and he tells them the name of the place--which is generally hell. Now of this detached and rational use of satire there is one great example in this book. Even _Gulliver's Travels_ is hardly more reasonable than Martin Chuzzlewit's travels in the incredible land of the Americans. Before considering the humour of this description in its more exhaustive and liberal aspects, it may be first remarked that in this American part of _Martin Chuzzlewit_, Dickens quite specially sharpens up his own more controversial and political intelligence. There are more things here than anywhere else in Dickens that partake of the nature of pamphleteering, of positive challenge, of sudden repartee, of pugnacious and exasperating query, in a word of everything that belongs to the pure art of controversy as distinct not only from the pure art of fiction but even also from the pure art of satire. I am inclined to think (to put the matter not only shortly but clumsily) that Dickens was never in all his life so strictly clever as he is in the American part of _Martin Chuzzlewit_. There are places where he was more inspired, almost in the sense of being intoxicated, as, for instance, in the Micawber feasts of _David Copperfield_; there are places where he wrote more carefully and cunningly, as, for instance, in the mystery of _The Mystery of Edwin Drood_; there are places where he wrote very much more humanly, more close to the ground and to growing things, as in the whole of that admirable book _Great Expectations_. But I do not think that his mere abstract acuteness and rapidity of thought were ever exercised with such startling exactitude as they are in this place in _Martin Chuzzlewit_. It is to be noted, for instance, that his American experience had actually worked him up to a heat and habit of argument. A slave-owner in the Southern States tells Dickens that slave-owners do not ill-treat their slaves, that it is not to the interest of slave-owners to ill-treat their slaves.
