I don't understand why a Mark Rothko painting - as much as I love Mark Rothko - has to cost $73 million. I mean, I think $14 million is a pretty reasonable sum of money for a good Rothko painting. What's disturbing about this present moment is that these prices have been so out of control.

I will do a lot of research and create a lot of material for use in one painting. And then I go on discovering and working with a whole other range of material in another painting. I'm interested in a fairly comprehensive and orchestrated synthesis that might bring about a new situation consisting of this hidden material. I'm interested in hidden source material.

It's hard to fathom the psychology of the economics of art. I don't quite understand it, and I don't necessarily want to understand it.

I'm not so interested in this series of ruptures, where minimalism took over pop art, and then neo-expressionism was a triumph over that. I'm not interested in rupture - I'm interested in healing, bringing things together, building bridges. Not dismissing what has come before as a kind of modernist precedent, where one thing has to be broken in order to achieve something else. I don't believe in that kind of attitude. I think we're beyond that at this stage.

An artist makes something to be physically experienced by another person. It's a raw, freely chosen, interpersonal relationship between the maker and the viewer, so it's close to what a musical composer does, or a poet or a dancer. It is coming out of one's inner being.

For me, the whole idea of the radically new is tied to a close reconsideration of older sources. I like to give myself over to those sources, as points of origin, in order to bring things forward. My approach requires me to internalize my sources as much as possible in the hope that new themes might emerge. The material has to be internalized in order for it to live again. Ultimately, paintings reveal themselves on the basis of what they are. They are inseparable from the physical process that goes into their making.

Ideas in art may be quite evident, and sometimes they're hidden. Sometimes they're simple, and sometimes they're quite complex. Great works of art can be based on very simple ideas, but it's all in the making, isn't it? It's in the facture.
