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.

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.

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.

What excites me and what I find most compelling is clearly not what excites other artists. It comes from my own idiosyncratic background and what I'm drawn to. Maybe this is a result of having lived in Naples during a formative period of time. I'm interested in telling a unique story in a very intense way.

I have been very influenced by the Japanese concept of space - the preciousness of space, and how one's environment can be shaped to make the most out of limited resources. That's the kind of thing we need to look at again - how momentous the results can be from very subtle changes.

I have a fairly unwieldy set of concerns that go into determining what I do in the paintings, such as the history of the decorative, patterns of cultural migration, Islamic art and design, Byzantine architecture, the annals of natural history, as well as contemporary painting. All of these things are filtered through my own sense of cultural urgency. How I proceed with the work has to do with how I respond to this instinctively chosen mass of materials. I'm weighing many things and making many decisions before I even get started on a painting.

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.
