"It is the best of all impossible worlds."

But when all is said, as I have remarked before, the chief fountain in Dickens of what I have called cheerfulness, and some prefer to call optimism, is something deeper than a verbal philosophy. It is, after all, an incomparable hunger and pleasure for the vitality and the variety, for the infinite eccentricity of existence. And this word "eccentricity" brings us, perhaps, nearer to the matter than any other. It is, perhaps, the strongest mark of the divinity of man that he talks of this world as "a strange world," though he has seen no other. We feel that all there is is eccentric, though we do not know what is the centre. This sentiment of the grotesqueness of the universe ran through Dickens's brain and body like the mad blood of the elves. He saw all his streets in fantastic perspectives, he saw all his cockney villas as top heavy and wild, he saw every man's nose twice as big as it was, and very man's eyes like saucers. And this was the basis of his gaiety -- the only real basis of any philosophical gaiety. This world is not to be justified as it is justified by the mechanical optimists; it is not to be justified as the best of all possible worlds. Its merit is not that it is orderly and explicable; its merit is that it is wild and utterly unexplained. Its merit is precisely that none of us could have conceived such a thing, that we should have rejected the bare idea of it as miracle and unreason. It is the best of all impossible worlds.

-Charles Dickens (1906)
