People of taste tell us nowadays that Renoir is a great eighteenth-century painter. But in so saying they forget the element of Time, and that it took a great deal of time, even at the height of the nineteenth century, for Renoir to be hailed as a great artist. To succeed thus in gaining recognition, the original painter or the original writer proceeds on the lines of the oculist. The course of treatment they give us by their painting or by their prose is not always pleasant. When it is at an end the practitioner says to us: 'Now look!' And, lo and behold, the world around us (which was not created once and for all, but is created afresh as often as an original artist is born) appears to us entirely different from the old world, but perfectly clear. Women pass in the street, different from those we formerly saw, because they are Renoirs, those Renoirs we persistently refused to see as women. The carriages, too, are Renoirs, and the water, and the sky; we feel tempted to go for a walk in the forest which is identical with the one which when we first saw it looked like anything in the world except a forest, like for instance a tapestry of innumerable hues but lacking precisely the hues peculiar to forests. Such is the new and perishable universe which has just been created. It will last until the next geological catastrophe is precipitated by a new painter or writer of original talent.
