Heidegger wrote a book called Was Ist Das Ding - What Is a Thing? which was kind of interesting and influential to me, as a matter of fact. It's a small paperback, which I read. It's about the nature of thingness; what is it? It's a very penetrating analysis of that, and I think a rather influential book. I know other artists who have read it and come up with it.

I know where the mistakes are. Nothing is perfect and I understand that.

I had always spoken about the space between the art object and the person looking at it as this dynamic space, which I referred to over and over. So the idea of the space between two things was sort of interesting to me.

A text makes the word more specific. It really kind of defines it within the context in which it is being used. If it is just taken out of a context and presented as a sort of object, which is what - you know, which is a contemporary art idea, you know. It is like an old surrealist idea or an old cubist idea to take something out of context and put it in a completely different context. And it sort of gives it a different meaning and creates another world, another kind of world in which we enter.

I was a guest at CalArts. John Baldessari invited me out a few times. I've been there. I've been in Pasadena, taught out at Boulder, University of Colorado. And I've taught in Europe. I've lectured and taught. I've taught at the École des Beaux-Arts in Nigne [sp]. I was there for a couple of weeks, I was there. I've taught all over - in Switzerland, Germany.

I am very generous with my dealers in terms of the art that they have of mine. They all have a very good selection of work that they can work with. And it is up to them to find the dealers. I don't interfere with their selling.

I think words speak to us even though they may be written on a wall. So we hear them in our mind. We say it to ourselves. But they are also visual things. You draw them. They are designed. They are colored. They have a certain size. I put them in a certain place. So they are objects that have to be - artistic decisions have to be made in terms of the color and the size and the line and whatever.
