We need saints; we need this head - this talking head - to communicate. Every single religion you have people that go in-between, that can talk to god or communicate ideas. Then there are the talking heads in the news every time we watch TV. No matter how complex, you still need a person there to tell you what happened: a storyteller of sorts. I find that fascinating that we feel so attached to this primitive mode of connection, this primitive interface to the world.

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.

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."

I'm not creating art that starts with politics or starts with ethics. I feel I am a conceptual artist because my art is more concerned with epistemology than ethics or politics or even aesthetics.

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.

If you find an idea without form, please let me know because I would love to take a picture of it.

I think that the development of any culture has something to do with the way people deal with the concept of illusion. The fact that the sound of my voice and the way I modulate it creates pictures in your head... in order for us to accumulate knowledge, we have to create symbolic exchanges that let ourselves be fooled temporarily by something that's not there - by a substitute for reality. When you talk about representation, you're talking about language.
