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

My first reaction to finding Robert Smithson's Spiral Jetty in a book was, Wow, what a great photograph! I could not believe that someone had gone to so much trouble just to end up with a picture.

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.

When someone tells you it’s a grain of sand, there’s a moment where your reality falls apart and you have to reconstruct it. You have to step back and ask what the image is and what it means.

I think pure light has something to do with actually seeing everything at once. It's kind of a nirvana of sorts.

Now that photography is a digital medium, the ghost of painting is coming to haunt it: photography no longer retains a sense of truth. I think that's great, because it frees photography from factuality, the same way photography freed painting from factuality in the mid-nineteenth century.
