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

There's one Baldessari work I genuinely love and would like to own, maybe because of my Midwestern roots and love of driving alone. 'The backs of all the trucks passed while driving from Los Angeles to Santa Barbara, California, Sunday, 20 January 1963' consists of a grid of 32 small color photographs depicting just what the title says.

It's art that pushes against psychological and social expectations, that tries to transform decay into something generative, that is replicative in a baroque way, that isn't about progress, and wants to - as Walt Whitman put it - 'contain multitudes.'

Contrary to popular opinion, things don't go stale particularly fast in the art world.

These days, newish art can be priced between $10,000 and $25,000. When I tell artists that a new painting by a newish artist should go for around $1,200, they look at me like I'm a flesh-eating virus.

Yes, 85 percent of the art you see isn't any good. But everyone has a different opinion about which 85 percent is bad. That in turn creates fantastically unstable interplay and argument.

Auction houses run a rigged game. They know exactly how many people will be bidding on a work and exactly who they are. In a gallery, works of art need only one person who wants to pay for them.
