"The thing that drove Dickens forward into a form of art for which he was not really suited, and at the same time caused us to remember him, was simply the fact that he was a moralist, the consciousness of ‘having something to say’. 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."
