"Artists, like cats, communicate abstractly, at a remove. This is why artists hate to be asked what their work means. Even if what they make is a picture of a landscape, or a race riot, it's not 'about' only those things. It's about much more -- including itself, its materials and how they were used, and how the artist sees the world."
"As for art itself, that's much more like a dog: never quite behaving, making a mess, costing a lot, always making you get supplies, but paying you back in wonder and delight."
-- Jerry Saltz, in his book "How to Be An Artist"
