Just as Pollock used the drip to meld process and product, Richter 'found' and used the smudge and the blur to ravish the eye, creating works of psychic and physical power.

Our culture now wonderfully, alchemically transforms images and history into artistic material. The possibilities seem endless and wide open.

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 think that cynicism is the enemy. Cynicism thinks it knows how things work. "Oh yeah, you know how that works." I think uncertainty is the thing you have to keep embracing. You have to keep saying, I actually don't know, and going out is going to tell me something every time.

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.

A great artist has a unique vision...obsession. They are someone willing to fail flamboyantly.

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.
