Abstraction is one of the greatest visionary tools ever invented by human beings to imagine, decipher, and depict the world.

Poor Georgia O'Keeffe. Death didn't soften the opinions of the art world toward her paintings.

Maybe the museum [of Arts and Design ]needs to follow the advice of its acronym and not be afraid to go a little M.A.D.

Pictures artists staged their own images or copied or cut out others already in existence. The viewer took them in separately, in sometimes paradoxical waves: an original image, then the manipulations of it, then the places where image and idea intersected. This created a crucial perceptual glitch that irony and understanding filled.

I'm noticing a new approach to art making in recent museum and gallery shows. It flickered into focus at the New Museum's 'Younger Than Jesus' last year and ran through the Whitney Biennial, and I'm seeing it blossom and bear fruit at 'Greater New York,' MoMA P.S. 1's twice-a-decade extravaganza of emerging local talent.

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.

Don't talk. I can't hear myself see.
