The secret of food lies in memory - of thinking and then knowing what the taste of cinnamon or steak is.

Chris Ofili's suave, stippled, visually tricked-out paintings of the nineties, with their allover fields of shimmering dots and clumps of dung, are like cave paintings of modern life. They crackle with optical cockiness, love, and massive amounts of painterly mojo.

Giorgio Morandi's paintings make me think that artists may not totally choose, or even control, their subjects or style.

Art schools are partly the villain here. (Never mind that I teach in them.) This generation of artists is the first to have been so widely credentialed, and its young members so fetishize the work beloved by their teachers that their work ceases to talk about anything else. Instead of enlarging our view of being human, it contains safe rehashing of received ideas about received ideas. This is a melancholy romance with artistic ruins, homesickness for a bygone era. This yearning may be earnest, but it stunts their work, and by turn the broader culture.

Abstract Expressionism - the first American movement to have a worldwide influence - was remarkably short-lived: It heated up after World War II and was all but done for by 1960 (although visit any art school today and you'll find a would-be Willem de Kooning).

A saboteur in the house of art and a comedienne in the house of art theory, Lawler has spent three decades documenting the secret life of art. Functioning as a kind of one-woman CSI unit, she has photographed pictures and objects in collectors' homes, in galleries, on the walls of auction houses, and off the walls, in museum storage.

Decades ago, Gerhard Richter found a painterly philosopher's stone. Like Jackson Pollock before him, he discovered something that had been in painting all along, always overlooked or discounted.
