Dickens devoted his genius in a somewhat special sense to the description of happiness. No other literary man of his eminence has made this central human aim so specially his subject matter. Happiness is a mystery--generally a momentary mystery--which seldom stops long enough to submit itself to artistic observation, and which, even when it is habitual, has something about it which renders artistic description almost impossible. There are twenty tiny minor poets who can describe fairly impressively an eternity of agony; there are very few even of the eternal poets who can describe ten minutes of satisfaction. Nevertheless, mankind being half divine is always in love with the impossible, and numberless attempts have been made from the beginning of human literature to describe a real state of felicity. Upon the whole, I think, the most successful have been the most frankly physical and symbolic; the flowers of Eden or the jewels of the New Jerusalem. Many writers, for instance, have called the gold and chrysolite of the Holy City a vulgar lump of jewellery. But when these critics themselves attempt to describe their conceptions of future happiness, it is always some priggish nonsense about "planes," about "cycles of fulfilment," or "spirals of spiritual evolution." Now a cycle is just as much a physical metaphor as a flower of Eden; a spiral is just as much a physical metaphor as a precious stone. But, after all, a garden is a beautiful thing; whereas this is by no means necessarily true of a cycle, as can be seen in the case of a bicycle. A jewel, after all, is a beautiful thing; but this is not necessarily so of a spiral, as can be seen in the case of a corkscrew. Nothing is gained by dropping the old material metaphors, which did hint at heavenly beauty, and adopting other material metaphors which do not even give a hint of earthly beauty. This modern or spiral method of describing indescribable happiness may, I think, be dismissed. Then there has been another method which has been adopted by many men of a very real poetical genius. It was the method of the old pastoral poets like Theocritus. It was in another way that adopted by the elegance and piety of Spenser. It was certainly expressed in the pictures of Watteau; and it had a very sympathetic and even manly expression in modern England in the decorative poetry of William Morris. These men of genius, from Theocritus to Morris, occupied themselves in endeavouring to describe happiness as a state of certain human beings, the atmosphere of a commonwealth, the enduring climate of certain cities or islands. They poured forth treasures of the truest kind of imagination upon describing the happy lives and landscapes of Utopia or Atlantis or the Earthly Paradise. They traced with the most tender accuracy the tracery of its fruit-trees or the glimmering garments of its women; they used every ingenuity of colour or intricate shape to suggest its infinite delight. And what they succeeded in suggesting was always its infinite melancholy. William Morris described the Earthly Paradise in such a way that the only strong emotional note left on the mind was the feeling of how homeless his travellers felt in that alien Elysium; and the reader sympathised with them, feeling that he would prefer not only Elizabethan England but even twentieth-century Camberwell to such a land of shining shadows. Thus literature has almost always failed in endeavouring to describe happiness as a state. Human tradition, human custom and folk-lore (though far more true and reliable than literature as a rule) have not often succeeded in giving quite the correct symbols for a real atmosphere of _camaraderie_ and joy. But here and there the note has been struck with the sudden vibration of the _vox humana_. In human tradition it has been struck chiefly in the old celebrations of Christmas. In literature it has been struck chiefly in Dickens's Christmas tales.
