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.

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

'Summer of Love: Art of the Psychedelic Era,' the Whitney Museum's 40th-anniversary trip down counterculture memory lane, provides moments of buzzy fun, but it'll leave you only comfortably numb. For starters, it may be the whitest, straightest, most conservative show seen in a New York museum since psychedelia was new.

To me, the building [of Museum of Arts and Design]now looks like a lovely jewel box, and the tiled façade reminds me of a heat shield.

I love art dealers. In some ways, they're my favorite people in the art world. Really. I love that they put their money where their taste is, create their own aesthetic universes, support artists, employ people, and do all of this while letting us see art for free. Many are visionaries.

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.

Make an enemy of jealousy and envy. As fast and soon as you can…. The art world is high school with money.
