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."

Illusions as bad as mine make people aware of the fallacies of visual information and the pleasure to be derived from such fallacies.

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 don't want to fool people. If I wanted to do that, I would be working with virtual reality. I want to operate on the other level, the other end of the illusion spectrum. I want to create the worst possible illusions so it doesn't really fool people, but instead give people a measure of their own belief. It makes them aware of how much they need to be fooled in order to understand the world around them.

The moment when one thing turns into another is the most beautiful moment. A combination of sounds turns into music. And that applies to everything.

Art objects are inanimate sad bits of matter hanging in the dark when no one is looking. The artist only does half the work; the viewer has to come up with the rest, and it is by empowering the viewer that the miracle of art gains its force.

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.
