Art is for anyone. It just isn't for everyone. Still, over the past decade, its audience has hugely grown, and that's irked those outside the art world, who get irritated at things like incomprehensibility or money.

When I criticize Joseph Beuys or Francis Bacon, nobody calls those opinions anti-male. Putting female artists or their subject matter off-limits is itself sexist and limiting.

I also take pleasure in the so-called negative power in Grotjahn's work. That is, I love his paintings for what they are not. Unlike much art of the past decade, Grotjahn isn't simply working from a prescribed checklist of academically acceptable, curator-approved 'isms' and twists.

Art is a self-replicating force.

All great contemporary artists, schooled or not, are essentially self-taught and are de-skilling like crazy. I don't look for skill in art... skill has nothing to do with technical proficiency... I'm interested in people who rethink skill, who redefine or reimagine it: an engineer, say, who builds rockets from rocks.

There are many, many art worlds. Art contains multitudes.

The art world is molting - some would say melting. Galleries are closing; museums are scaling back.
