I am good in the fact that most of my reviews have been very positive really. I get pretty good reviews. There have been some that aren't - critical. I think they are extremely - the people that wrote them really don't understand what they are looking at quite frankly or have a very preconceived notion of what conceptual art should be or where I am at or the fact that I may change what I have done from what I did 20 years ago. But there is always some reason that they just sort of get it wrong. And so it certainly doesn't affect my work.

But if I did read, say, [Maurice] Merleau-Ponty, for instance, it always seemed to me that the parts that I understood in what he was talking about - and I read him because - well, he wrote a book, well, the Phenomenology of Perception [New York: Humanities Press, 1962]. And it seemed to me that perception had a lot do with how we take in art.

I'm fortunate in one respect; that I don't have a lot of work in my studio. Most of it's out, gone; either sold or in galleries. I work with a lot of galleries.

So it sort of dawned on me that you have to build into your work the fact that it's going to be shown in different kinds of places and different kinds of light. And the fact that the surroundings and where you're going to be shown is always changing, so that should really not affect the meaning of the work. It should be part of what the work is about.

I usually, if I give a talk, I don't usually prepare anything. I just say - you know, I may stop talking by showing some video or slides of what I do but mainly I try to respond to what problems people have with my work.

I'm my own worst critic. I mean, I know what's wrong with everything that I've done.

I am very easy. I like to have my work out. I am not restrictive about any of that. It is the collectors that are possessive, not me, not me.
