Sculpture according to Richard Serra

There are a lot of people around still making objects, but I'm interested in a situation where what we call the sculpture is a catalyst for walking and looking and thinking about what you're looking at. If this work can do that, if it can just inform and change how you see, even minutely, that's a reason to do it. I mean, nobody thinks sculpture's going to change the world.
