Art's means of representing a thing – style, technique and the object represented – are circumstances of art, just as the artist's individual qualities (way of life, abilities, environment and so on) are circumstances of art. Art can just as well be made in harmony with the circumstances of its making as in defiance of them. In itself art is neither visible nor definable: all that is visible and imitable is its circumstances, which are easily mistaken for the art itself.
