“Well sure, my sculptures are floor pieces. Each one, like any area on the surface of the earth, supports a column of air that weighs – what is it?”

Carl Andre (1935) American artist

14.7 pounds per square inch. So in a sense, that might represent a column. It's not an idea, it's a sense of something you know, a demarked place. Somehow I think I always thought of it going that way, rather than an idea of a narrowing triangle going to the center of the earth.. .I have nothing to do with Conceptual art [in contrast to his Physical Art, as Carl Andre called his sculpture art already in 1969]]. I'm not interested in ideas. If I were interested in ideas, I'd be in a field where what we think in is ideas.. .I don't really know what an idea is. One thing for me is that if I can frame something in language, I would never make art out of it. I make art out of things which cannot be framed in any other way.
