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 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.

Design is meant to grab you and win you over. It is meant to function in a way so as to make life easier. Obviously painting has to do with something quite beyond that. It's not about communication per se. It doesn't necessarily telegraph anything. It's more about understanding who we are and where we come from.

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.

I'm not so interested in the effort that it takes to have a self-promotional outlook. I believe in being quiet and making my work and just trying to make discoveries and let the painting evolve.

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.

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.
