If you want a commercial success - it's the confusion of commerce with art. A successful play is not considered to be the best written. It is the one that sells the most tickets. Those standards are destructive [to theatre].

Writing should be useful. If it can’t instruct people a little bit more about the responsibilities of consciousness, there’s no point in doing it.

Naturally, no writer who's any good at all would sit down and put a sheet of paper in a typewriter and start typing a play unless he knew what he was writing about.

When a critic sets himself up as an arbiter of morality, a judge of the matter and not the manner of a work, he is no longer a critic; he is a censor.

Art should never try to be popular.

To a certain extent I imagine a play is completely finished in my mind - in my case, at any rate - without my knowing it, before I sit down to write.

If you have no wounds, how can you know if you're alive?
