I think you say the word in your mind anyway, you know. When you look at a word, you say it.

The space between things is important to me. The projections, that darkness between the words or the images is very important.

There's a kind of poetic aspect to inert gas. And remember, first of all, they were completely unknown a hundred years earlier. We just didn't know about them. And then when they were discovered in the atmosphere, the idea that this is a material that would breathe in and exhale and becomes part of us for a while made it even more intriguing. The names, the Greek names, are interesting, too - if you translate neon, xenon and so forth are kind of interesting.

I certainly don't believe that people can read other people's minds.

The words represent ideas first of all. That is something you have to understand. I mean, it is not just an object, but it is an object with a history and it is loaded with all kinds of implications and ideas. They exist in the world in a very special way. So they kind of represent some aspect of the world that we perceive, as do photographs, as do drawings of trees or whatever. And they are not a one to one. They are not the world, but they kind of refer to the world and they also exist in the world.

I have never had a shortage of ideas for shows. I always just do them and the gallerists don't - they stopped long ago trying to tell me what I should show in their gallery. They just don't even do it. I show whatever I want to show. They are very happy and as far as I know, they have always been very pleased with whatever I have shown, even if it is nothing to sell.

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.
