'Untitled' is a time machine that can transport you to 1992, an edgy moment when the art world was crumbling, money was scarce, and artists like Tiravanija were in the nascent stages of combining Happenings, performance art, John Cage, Joseph Beuys, and the do-it-yourself ethos of punk. Meanwhile, a new art world was coming into being.

Summer is a great time to visit art museums, which offer the refreshing rinse of swimming pools - only instead of cool water, you immerse yourself in art.

Venice is the perfect place for a phase of art to die. No other city on earth embraces entropy quite like this magical floating mall.

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.

The style of ancient Egyptian art is transcendently clear, something 8-year-olds can recognize in an instant. Its consistency and codification is one of the most epic visual journeys in all art, one that lasts 30 dynasties spread over 3,000 years.

Artschwager's art always involves looking closely at surfaces, questions what an object is, wants to make you forget the name of the thing you're looking at so that it might mushroom in your mind into something that triggers unexpected infinities.

It's art that pushes against psychological and social expectations, that tries to transform decay into something generative, that is replicative in a baroque way, that isn't about progress, and wants to - as Walt Whitman put it - 'contain multitudes.'

'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.

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.'

It took me twenty years to get Steven Parrino's work. From the time I first saw his art, in the mid-eighties, I almost always dismissed it as mannered, Romantic, formulaic, conceptualist-formalist heavy-metal boy-art abstraction.

A sad fact of life lately at the Museum of Modern Art is that when it comes to group shows of contemporary painting from the collection, the bar has been set pretty low.

John Currin's exaggerated realism and his twisted women kept me off balance, never knowing if they were sincere or ironic or some new emotion.

Urs Fischer specializes in making jaws drop. Cutting giant holes in gallery walls, digging a crater in Gavin Brown's gallery floor in 2007, creating amazing hyperrealist wallpaper for a group show at Tony Shafrazi: It all percolates with uncanny destructiveness, operatic uncontrollability, and barbaric sculptural power.

There's one Baldessari work I genuinely love and would like to own, maybe because of my Midwestern roots and love of driving alone. 'The backs of all the trucks passed while driving from Los Angeles to Santa Barbara, California, Sunday, 20 January 1963' consists of a grid of 32 small color photographs depicting just what the title says.

When the purse strings tighten up at museums, the institutions usually cut back and cancel shows. That's exactly the wrong reaction. In fact, now is a good time for them to loosen up - a chance to breathe and experiment a little - and go for the juicy solution lurking in their own basements.

New Yorkers only cross water for visual culture if the water is an ocean. The East River throws us for a huge loop. If we started going to Queens and the Bronx for visual culture, many of our rent, space, and crowding problems would be over indefinitely.

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