I quote from it: "Someone asked me once if abstraction was subversive. I did not think so. And I don't think so now. It's subversive in the sense that it makes or helps people to think freely. But it's not trying to bring some other structure down to be seen. It makes its own space or has invented its own space. A space that didn't previously exist. This, coincidentally, Morandi did."
