"When I speak of the aspiration towards the beautiful, of the ideal as the ultimate aim of art, which grows from a yearning for that ideal, I am not for a moment suggesting that art should shun the 'dirt' of the world. On the contrary! the artistic image is always a metonym, where one thing is substituted for another, the smaller for the greater. To tell of what is living, the artist uses something dead; to speak of the infinite, he shows the finite. Substitution... the infinite cannot be made into matter, but it is possible to create an illusion of the infinite: the image."
