The very paradigm of revolution, of right versus wrong, good versus bad, is a relic with no bearing on the present. Yet artists, exhibitions, and curators valorize the sixties. People who wrote about these artists 30 years ago still write about them in the same ways, often for the same magazines.

Early-twentieth-century abstraction is art's version of Einstein's Theory of Relativity. It's the idea that changed everything everywhere: quickly, decisively, for good.

It is not possible to overstate the influence of Paul Cezanne on twentieth-century art. He's the modern Giotto, someone who shattered one kind of picture-making and invented a new one that the world followed.

As I went through 'This Progress,' one of two performance pieces by Tino Sehgal that transform Frank Lloyd Wright's emptied-out spiral into a dreamy Socratic-purgatorial journey, the museum literally fell away. I was suspended in some weird nonspace.

I see artists bored by light-without-heat, irked at gigantic galleries' pushing out art-as-product, leaving behind the over determined for the undetermined, guided by interior voices and bringing us out of a long tunnel to new blueness.

When people in stadiums do the Wave, it's the group-mind collective organism spontaneously organizing itself to express an emotion, pass time, and reflect the joy of seeing the rhythms of many as one, a visual rhyming or music in which everyone senses where the motion is going.

Of course art world ethics are important. But museums are no purer than any other institution or business. Academics aren't necessarily more high-minded than gallerists.
