Where Cezanne captured and intensified shards of the eternal (every pear far more sharply defined than it could be in life), Monet portrayed the changeability and flux of every moment. 'The Water Lilies' give you a jittery, amorphous sense of a world seen at the speed of light.

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."

Appropriation is the idea that ate the art world. Go to any Chelsea gallery or international biennial and you'll find it. It's there in paintings of photographs, photographs of advertising, sculpture with ready-made objects, videos using already-existing film.

The forties, seventies, and the nineties, when money was scarce, were great periods, when the art world retracted but it was also reborn.

Art is a way of showing the outside world what your inside world is like.

Once artists are expected to shock, it's that much harder for them to do so.

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