From his lecture at the PEN World Voices Festival in May, 2012:
Originality is dangerous. If you want to increase the sum of what is possible for human beings to say, to know, to understand, and therefore in the end to be, you actually have to go to the edge and push outwards…. This is the kind of art whose right to exist we must not only defend but celebrate. Art is not entertainment. At its very best, it’s a revolution.
That’s exactly what I want to do: add to the long list of possible thoughts human beings can have. What other reason are any of us here, really? When really we’re at our best, that’s what we do.
