The greatest work of art about New York? The question seems nebulous. The city's magic and majesty are distilled in the photographs of Alfred Stieglitz and Paul Strand.

Lucian Freud's career affirms that the only thing an artist can do is remain true to whatever vision, (lack of) talent, or ideas that happened to pick them in order to be made known to the world.

Probably only an art-worlder like me could assign deeper meaning to something as simple and silly as Tebowing. But, to us, anytime people repeat a stance or a little dance, alone or together, we see that it can mean something. Imagistic and unspoken language is our thing.

Photography is the easiest thing to make, and one of the hardest things to make well.

Being critical of art is a way of showing art respect. No sports writer would say, "Well the Yankees had a great season this year." No food critic would get a bad meal and say, "Oh, it was so lovely." It always strikes me as odd when people say, "Why do you write negatively about any art?" I think that everybody has mixed feelings about everything - even Goya. I mean, I look at Rembrandt sometimes and I hear a voice in my head go, "It's pretty brown."

I think that a lot of artists have succeeded in making what I might call "curator's art." Everybody's being accepted, and I always want to say, "Really? That's what you've come for? To make art that looks a lot like somebody else's art?" If I am thinking of somebody else's art in front of your art, that's a problem.

After its hothouse incubation in the seventies, appropriation breathed important new life into art. This life flowered spectacularly over the decades - even if it's now close to aesthetic kudzu.
