Painting seems to be to the eye what dancing is to the limbs. When that has educated the frame to self-possession, to nimbleness,to grace, the steps of the dancing-master are better forgotten; so painting teaches me the splendor of color and the expression of form, and as I see many pictures and higher genius in the art, I see the boundless opulence of the pencil, the indifferency in which the artist stands free to choose out of the possible forms.
