He is always preaching a sermon, and that is the final secret of his inventiveness. For you can only create if you can care. Types like Squeers and Micawber could not have been produced by a hack writer looking for something to be funny about. A joke worth laughing at always has an idea behind it, and usually a subversive idea. Dickens is able to go on being funny because he is in revolt against authority, and authority is always there to be laughed at. There is always room for one more custard pie.

His radicalism is of the vaguest kind, and yet one always knows that it is there. That is the difference between being a moralist and a politician. He has no constructive suggestions, not even a clear grasp of the nature of the society he is attacking, only an emotional perception that something is wrong, all he can finally say is, ‘Behave decently’, which, as I suggested earlier, is not necessarily so shallow as it sounds. Most revolutionaries are potential Tories, because they imagine that everything can be put right by altering the shape of society; once that change is effected, as it sometimes is, they see no need for any other. Dickens has not this kind of mental coarseness. The vagueness of his discontent is the mark of its permanence. What he is out against is not this or that institution, but, as Chesterton put it, ‘an expression on the human face.’ Roughly speaking, his morality is the Christian morality, but in spite of his Anglican upbringing he was essentially a Bible-Christian, as he took care to make plain when writing his will. In any case he cannot properly be described as a religious man. He ‘believed’, undoubtedly, but religion in the devotional sense does not seem to have entered much into his thoughts(3). Where he is Christian is in his quasi-instinctive siding with the oppressed against the oppressors. As a matter of course he is on the side of the underdog, always and everywhere. To carry this to its logical conclusion one has got to change sides when the underdog becomes an upperdog, and in fact Dickens does tend to do so. He loathes the Catholic Church, for instance, but as soon as the Catholics are persecuted (Barnaby Rudge) he is on their side. He loathes the aristocratic class even more, but as soon as they are really overthrown (the revolutionary chapters in A Tale of Two Cities) his sympathies swing round. Whenever he departs from this emotional attitude he goes astray. A well-known example is at the ending of David Copperfield, in which everyone who reads it feels that something has gone wrong. What is wrong is that the closing chapters are pervaded, faintly but not noticeably, by the cult of success. It is the gospel according to Smiles, instead of the gospel according to Dickens. The attractive, out-at-elbow characters are got rid of, Micawber makes a fortune, Heep gets into prison — both of these events are flagrantly impossible — and even Dora is killed off to make way for Agnes. If you like, you can read Dora as Dickens's wife and Agnes as his sister-in-law, but the essential point is that Dickens has ‘turned respectable’ and done violence to his own nature. Perhaps that is why Agnes is the most disagreeable of his heroines, the real legless angel of Victorian romance, almost as bad as Thackeray's Laura.

No grown-up person can read Dickens without feeling his limitations, and yet there does remain his native generosity of mind, which acts as a kind of anchor and nearly always keeps him where he belongs. It is probably the central secret of his popularity. A good-tempered antinomianism rather of Dickens's type is one of the marks of Western popular culture. One sees it in folk-stories and comic songs, in dream-figures like Mickey Mouse and Pop-eye the Sailor (both of them variants of Jack the Giant-killer), in the history of working-class Socialism, in the popular protests (always ineffective but not always a sham) against imperialism, in the impulse that makes a jury award excessive damages when a rich man's car runs over a poor man; it is the feeling that one is always on the wrong side of the underdog, on the side of the weak against the strong. In one sense it is a feeling that is fifty years out of date.
