I don't only write about English literature; I also write about chaos theory and... ants. I can understand ants.

I think literary theory has not been terribly good for English studies in a while. It's not that theory isn't interesting, but it isn't about books, or the idiosyncrasies and complexities of putting language together.

Plays are the marathon of scriptwriting. You fix on a point somewhere in the middle distance, and you start running, and you don't stop until you get to the end. The theory is that you have something you cannot not say: this is the engine that propels you through to the last page.
