Talking about the particles, I know I don't have any special theory of particles. It's just the way it came out and that's the way I want to do it. Also, there are advantages to particles: you can't break them; they don't break apart. They don't have any rigid connections; there are no rigid connections to break. The particles are always shifting around a little bit and you have to kick them back into shape. It's like tuning a piano every once in a while. I like the idea of something being permanent by being non-rigid, being absolutely non-rigid but not having a rigid form that can be broken. But a theory of particles, I don't know. Maybe late one night after a few drinks I explained to Lucy Lippard a theory of particles. I'm sure I didn't remember the next day.
