For we must admit that flat people are not in themselves as big achievements as round ones, and also that they are best when they are comic. A serious or tragic flat character is apt to be a bore. Each time he enters crying "Revenge!" or "My heart bleeds for humanity!" or whatever his formula is, our hearts sink. One of the romances of a popular contemporary writer is constructed round a Sussex farmer who says, "I'll plough up that bit of gorse." There is the farmer, there is the gorse; he says he'll plough it up, he does plough it up, but it is not like saying "I'll never desert Mr. Micawber," because we are so bored by his consistency that we do not care whether he succeeds with the gorse or fails. If his formula was analysed and connected up with the rest of the human outfit, we should not be bored any longer, the formula would cease to be the man and become an obsession in the man; that is to say he would have turned from a flat farmer into a round one. It is only round people who are fit to perform tragically for any length of time and can move us to any feelings except humour and appropriateness. So now let us desert these two-dimensional people, and by way of transition to the round, let us go to _Mansfield Park_, and look at Lady Bertram, sitting on her sofa with pug. Pug is flat, like most animals in fiction. He is once represented as straying into a rose-bed in a cardboard kind of way, but that is all, and during most of the book his mistress seems to be cut out of the same simple material as her dog. Lady Bertram's formula is, "I am kindly, but must not be fatigued," and she functions out of it. But at the end there is a catastrophe. Her two daughters come to grief--to the worst grief known to Miss Austen's universe, far worse than the Napoleonic wars. Julia elopes; Maria, who is unhappily married, runs off with a lover. What is Lady Bertram's reaction? The sentence describing it is significant: "Lady Bertram did not think deeply, but, guided by Sir Thomas, she thought justly on all important points, and she saw therefore in all its enormity, what had happened, and neither endeavoured herself, nor required Fanny to advise her, to think little of guilt and infamy." These are strong words, and they used to worry me because I thought Jane Austen's moral sense was getting out of hand. She may, and of course does, deprecate guilt and infamy herself, and she duly causes all possible distress in the minds of Edmund and Fanny, but has she any right to agitate calm, consistent Lady Bertram? Is not it like giving pug three faces and setting him to guard the gates of Hell? Ought not her ladyship to remain on the sofa saying, "This is a dreadful and sadly exhausting business about Julia and Maria, but where is Fanny gone? I have dropped another stitch"?
