“I was the only one to go to university, and the last thing my dad wanted was for…” — Sean Scully

I was doing an interview with a curator, and he asked me to sum up art in one word. Before he even finished asking the question, I said, 'Impurity.' Because that's it.

That's the job of art: to undo the logic of the world.

My art is based on impurity. You have to mix things from different refined cultures to get something raw, to make it go again.

When I was a teenager, I was very political.
