Where, if not from the Impressionists, do we get those wonderful brown fogs that come creeping down our streets, blurring the gas-lamps and changing the houses into monstrous shadows? To whom, if not to them and their master, do we owe the lovely silver mists that brood over our river, and turn to faint forms of fading grace curved bridge and swaying barge? The extraordinary change that has taken place in the climate of London during the last ten years is entirely due to a particular school of Art. You smile. Consider the matter from a scientific or a metaphysical point of view, and you will find that I am right. For what is Nature? Nature is no great mother who has borne us. She is our creation. It is in our brain that she quickens to life. Things are because we see them, and what we see, and how we see it, depends on the Arts that have influenced us. To look at a thing is very different from seeing a thing. One does not see anything until one sees its beauty. Then, and then only, does it come into existence. At present, people see fogs, not because there are fogs, but because poets and painters have taught them the mysterious loveliness of such effects. (The influence of the Impressionists on climate)
