The freeing of the artist in literary presentation, in other words, is as much a precondition of the desirable creation of adequate opinion on public matters as is the freeing of social inquiry. Men’s conscious life of opinion and judgment often proceeds on a superficial and trivial plane. But their lives reach a deeper level. The function of art has always been to break through the crust of conventionalized and routine consciousness. Common things, a flower, a gleam of moonlight, the song of a bird, not things rare and remote, are means with which the deeper levels of life are touched so that they spring up as desire and thought. This process is art.
Artists have always been the real purveyors of news, for it is not the outward happening in itself which is new, but the kindling by it of emotion, perception and appreciation.
John Dewey, Search for the Great Community (1927)
