At present, people see fogs, not because there are fogs, but because poets and painters have taught them the mysterious loveliness of such effects. There may have been fogs for centuries in London. I dare say there were. But no one saw them, and so we do not know anything about them. They did not exist till Art had invented them. Now, it must be admitted, fogs are carried to excess. They have become the mere mannerism of a clique, and the exaggerated realism of their method gives dull people bronchitis. Where the cultured catch an effect, the uncultured catch cold. And so, let us be humane, and invite Art to turn her wonderful eyes elsewhere. She has done so already, indeed. That white quivering sunlight that one sees now in France, with its strange blotches of mauve, and its restless violet shadows, is her latest fancy, and, on the whole, Nature reproduces it quite admirably. Where she used to give us Corots and Daubignys, she gives us now exquisite Monets and entrancing Pissaros. Indeed there are moments, rare, it is true, but still to be observed from time to time, when Nature becomes absolutely modern. Of course she is not always to be relied upon. The fact is that she is in this unfortunate position. Art creates an incomparable and unique effect, and, having done so, passes on to other things. Nature, upon the other hand, forgetting that imitation can be made the sincerest form of insult, keeps on repeating this effect until we all become absolutely wearied of it. Nobody of any real culture, for instance, ever talks nowadays about the beauty of a sunset. Sunsets are quite old−fashioned. They belong to the time when Turner was the last note in art. To admire them is a distinct sign of provincialism of temperament. Upon the other hand they go on. Yesterday evening Mrs. Arundel insisted on my going to the window, and looking at the glorious sky, as she called it. Of course I had to look at it. She is one of those absurdly pretty Philistines to whom one can deny nothing. And what was it? It was simply a very second−rate Turner, a Turner of a bad period, with all the painter's worst faults exaggerated and over−emphasised. Of course, I am quite ready to admit that Life very often commits the same error. She produces her false Renés and her sham Vautrins, just as Nature gives us, on one day a doubtful Cuyp, and on another a more than questionable Rousseau. Still, Nature irritates one more when she does things of that kind.
