Description:

'It has been sometimes said that art is a means of escape from 'the tyranny of the senses.' It may be so for the spectator; he may find that the spectacle of supreme works of art takes from the life of the senses something of its turbid fever. But this is possible for the spectator only because the artist, in producing those works, has gradually sunk his intellectual and spiritual ideas in sensuous form. He may live, as Keats lived, a pure life; but his soul, like that of Plato's false astronomer, becomes more and more immersed in sense, until nothing which lacks an appeal to sense has interest for him.'
