And Dickens sometimes succeeds in reaching a higher unity than that of mere plot. He takes one central idea, and makes of it the soul of his novel, animating and vivifying every part. That central idea in “Martin Chuzzlewit” is the influence of selfishness. The Chuzzlewits are a selfish race. Old Martin is selfish; and so, with many good qualities and possibilities of better things, is his grandson, young Martin. The other branch of the family, Anthony Chuzzlewit and his son Jonas, are much worse. The latter especially is a horrible creature. Brought up to think of nothing except his own interests and the main chance, he is only saved by an accident from the crime of parricide, and afterwards commits a murder and poisons himself. As his career is one of terrible descent, so young Martin’s is one of gradual regeneration from his besetting weakness. He falls in love with his cousin Mary—the only unselfish member of the family, by the bye—and quarrels about this love affair with his grandfather, and so passes into the hard school of adversity. There he learns much. Specially valuable is the teaching which he gets as a settler in the swampy backwoods of the United States in company with Mark Tapley, jolliest and most helpful of men. On his return, he finds his grandfather seemingly under the influence of Pecksniff, the hypocrite, the English Tartuffe. But that, as I have already mentioned, is only a ruse. Old Martin is deceiving Pecksniff, who in due time receives the reward of his deeds, and all ends happily for those who deserve happiness. Such is something like a bare outline of the story, with the beauty eliminated. For what makes its interest, we must go further, to the household of Pecksniff with his two daughters, Charity and Mercy, and Tom Pinch, whose beautiful, unselfish character stands so in contrast to that of the grasping self-seekers by whom he is surrounded; we must study young Martin
