It is all but impossible for people to talk about art and morality in the same sentence these days, a phenomenon that G. K. Chesterton saw coming, several decades ago. Consider the following from his essay "Tom Jones and Morality," published in his book All Things Considered:
"The truth is that [the inability to understand the complex view of morality presented in a book like Tom Jones] mark[s] a certain change in the general view of morals; not, I think, a change for the better. We have grown to associate morality in a book with a kind of optimism and prettiness; according to us, a moral book is a book about moral people. But the old idea was almost exactly the opposite; a moral book was a book about immoral people. A moral book was full of pictures like Hogarth's 'Gin Lane' or 'Stages of Cruelty,' or it recorded, like the popular broadsheet, 'God's dreadful judgment' against some blasphemer or murderer. There is a philosophical reason for this change. The homeless scepticism of our time has reached a sub-conscious feeling that morality is somehow merely a matter of human taste—an accident of psychology. And if goodness only exists in certain human minds, a man wishing to praise goodness will naturally exaggerate the amount of it that there is in human minds or the number of human minds in which it is supreme. Every confession that man is vicious is a confession that virtue is visionary. Every book which admits that evil is real is felt in some vague way to be admitting that good is unreal. The modern instinct is that if the heart of man is evil, there is nothing that remains good. But the older feeling was that if the heart of man was ever so evil, there was something that remained good—goodness remained good. An actual avenging virtue existed outside the human race; to that men rose, or from that men fell away. Therefore, of course, this law itself was as much demonstrated in the breach as in the observance. If Tom Jones violated morality, so much the worse for Tom Jones. Fielding did not feel, as a melancholy modern would have done, that every sin of Tom Jones was in some way breaking the spell, or we may even say destroying the fiction of morality. Men spoke of the sinner breaking the law; but it was rather the law that broke him. And what modern people call the foulness and freedom of Fielding is generally the severity and moral stringency of Fielding. He would not have thought that he was serving morality at all if he had written a book all about nice people. Fielding would have considered Mr. Ian Maclaren extremely immoral; and there is something to be said for that view. Telling the truth about the terrible struggle of the human soul is surely a very elementary part of the ethics of honesty. If the characters are not wicked, the book is. This older and firmer conception of right as existing outside human weakness and without reference to human error can be felt in the very lightest and loosest of the works of old English literature. It is commonly unmeaning enough to call Shakspere a great moralist; but in this particular way Shakspere is a very typical moralist. Whenever he alludes to right and wrong it is always with this old implication. Right is right, even if nobody does it. Wrong is wrong, even if everybody is wrong about it."
I strongly endorse Chesterton's analysis given here, and I believe that only when our critics are once again able to address the moral implications of literature in a sophisticated manner, and our authors openly analyze the moral choices of their characters with reference to some standard outside their own personal tastes, will our society, and indeed our civilization, have any hope of being thought fully healthy.
