In the back of every painting there's an entire universe that makes it possible for the painting to be there: an army of conservators, technicians, people who maintain these things, the market.

I think I'm an ambitious artist but you have to understand the measure of your influence on people. You're not going to change people's lives with your art. What you do is you give them a little pat so that you change the course of the direction that they're going.

The great challenge is how to make smart, intelligent art that can speak to everybody.

I hate to say I'm a photographer, because I learned photography as I went along. But I also hate to say I'm a painter, a draftsman, even an artist. I think it's good when you're confused about what you are; it means you haven't defined yourself as an artist yet.

I think art is the development of this interface between mind and matter, between mind and phenomenon, between what's inside of us and what's happening outside of us. It developed over the course of the last 35,000 years. We made a lot of improvements because it not only gave us the tools to understand the world better, but it also gave us better and better tools to do it. It's that continuous relationship: technology and discernment.

Every time you show something to somebody they're going in one direction, when they see that thing you did they're going to go off track - maybe towards a direction that you think is more important. They'll be more discerning, they'll probably see things a little bit more profoundly, they'll spend more time trying to understand what's in front of them.

Only in the 20th century, artists started taking the study of perception in a more humane way. They were thinking about the eye as being an instrument, the whole body as being a visual instrument. That sort of gave way a little bit with Cartesian­ - the "Cogito ergo sum" argument. It's not, "I think therefore I exist." It's, "I feel therefore I think therefore I exist."
