“No great artist ever sees things as they really are. If he did, he would cease to be an artist.”

so sad. An artist paints because it is a challenge to him – it is like trying to twist the devil. If you overcome it, there is no sport left. I don't even like to talk about painting. It is impossible to talk about painting because I don't know what it is. If I knew what it was I would get out a patent and then no one else would be able to paint.

The Principles of Success in Literature (1865)
Context: An artist produces an effect in virtue of the distinctness with which he sees the objects he represents, seeing them not vaguely as in vanishing apparitions, but steadily, and in their most characteristic relations. To this Vision he adds artistic skill with which to make us see. He may have clear conceptions, yet fail to make them clear to us: in this case he has imagination, but is not an artist. Without clear Vision no skill can avail. Imperfect Vision necessitates imperfect representation; words take the place of ideas.
