“ The light of a lamp enclosed within an alabaster vase is still lamplight, though shorn of lustre and toned to coloured softness. Even thus the spirit, immersed in things of sense presented to us by the figurative arts, is still spirit, though diminished in its intellectual clearness and invested with hues not its own. To fashion that alabaster form of art with utmost skill, to make it beautiful, to render it transparent, is the artist's function. But he will have failed of the highest if the light within burns dim, or if he gives the world a lamp in which no spiritual flame is lighted. ”
