"...It consisted in finding an opinion that had not a leg to stand on, and then giving it two legs to stand on."

Sadly, I did not realize until it was too late that yesterday was Charles Dickens's 200th birthday. To make up for it, I will include a quote about Dickens today, however. :-)

Dickens was among other things a satirist, a pure satirist...The essence of satire is that it perceives some absurdity inherent in the logic of some position, and that it draws that absurdity out and isolates it, so that all can see it...This is the great quality called satire; it is a kind of taunting reasonableness; and it is inseparable from a certain insane logic which is often called exaggeration. Dickens was more of a satirist than Thackeray for this simple reason: that Thackeray carried a man's principles as far as that man carried them; Dickens carried a man's principles as far as a man's principles would go. Dickens in short (as people put it) exaggerated the man and his principles; that is to say he emphasised them. Dickens drew a man's absurdity out of him; Thackeray left a man's absurdity in him...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.

...To put it roughly, he is not describing characters, he is satirising fads. To put it more exactly, he is not describing characters; he is persecuting heresies. There is one thing really to be said against his American satire; it is a serious thing to be said: it is an argument, and it is true. This can be said of Martin's wanderings in America, that from the time he lands in America to the time he sets sail from it he never meets a living man. He has travelled in the land of Laputa. All the people he has met have been absurd opinions walking about. The whole art of Dickens in such passages as these consisted in one thing. It consisted in finding an opinion that had not a leg to stand on, and then giving it two legs to stand on.
