Real life, life at last laid bare and illuminated — the only life in consequence of which can be said to be really lived – is literature, and life thus defined is in a sense all the time immanent in ordinary men no less than in the artist. But most men do not see it because they do not seek to shed light upon it. And therefore their past is like a photographic darkroom encumbered with innumerable negatives, which remain useless because the intellect has not developed them. But art, if it means awareness of our own life, means also awareness of the lives of other people – for style for the writer, no less than color for the painter, is a question not of technique but of vision: it is the revelation, which by direct and conscious methods would be impossible, of the qualitative difference, the uniqueness of the fashion in which the world appears to each one of us, a difference which, if there were no art, would remain forever the secret of every individual. Through art alone we are able to emerge from ourselves, to know what another person sees of a universe which is not the same as our own and of which, without art, the landscapes would remain as unknown to us as those that may exist on the moon. Thanks to art, instead of seeing one world only, our own, we see that world multiply itself and we have at our disposal as many worlds as there are original artists, worlds more different from the other than those which revolve in infinite space, worlds which, centuries after the extinction of the fire from which their light first emanated, whether it is called Rembrandt or Vermeer, send us still each one its special radiance.
–Marcel Proust, Time Regained
