The reason I love blogs so much right now is that I am seeing more critical voices appear, and that's kind of thrilling. I think a lot of critics in their forties or even their thirties have had their voice scared or trained out of them by the academy. I have nothing against the academy. I think it's brilliant and fantastic, but I also think that it's become almost monolithic. The same way a lot of art looks the same, a lot of writing can sound the same and quotes the same theorists.

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

Can space break? I mean the space of art galleries. Over the past 100 years, art galleries have gone from looking like Beaux Arts salons to simple storefronts to industrial lofts to the gleaming giant white cubes of Chelsea with their shiny concrete floors.

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.

'The Panorama' is also the last place anywhere in New York where the World Trade Center still stands, whole, as it stood in the early morning of September 11. I can also see the corner where I saw the first tower fall and howled out loud. Seeing the buildings again here is uplifting, healing.

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.'

The German ueber-photographer Andreas Gursky was the perfect pre-9/11 artist.
