I love Rauschenberg. I love that he created a turning point in visual history, that he redefined the idea of beauty, that he combined painting, sculpture, photography, and everyday life with such gall, and that he was interested in, as he put it, 'the ability to conceive failure as progress.'

As I made my way through 'On Line,' the austere, stridently dogmatic, sometimes revelatory exhibition 'about line' at MoMA, I found myself thinking, 'Someone please wake me when the seventies are over!' In the empire of curators, the sun never sets on the seventies. It is the undead decade.

Probably only an art-worlder like me could assign deeper meaning to something as simple and silly as Tebowing. But, to us, anytime people repeat a stance or a little dance, alone or together, we see that it can mean something. Imagistic and unspoken language is our thing.

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.

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.

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.
