The bad end unhappily, the good unluckily. That is what tragedy means. [A take-off on Oscar Wilde's "The good ended happily, and the bad unhappily. That is what Fiction means."]
A playwright is the litmus paper of the arts. He's got to be, because if he isn't working on the same wave length as the audience, no one would know what in hell he was talking about. He is a kind of psychic journalist, even when he's great.
A dramatic experience concerned with the mundane may inform but it cannot release; and one concerned essentially with the aesthetic politics of its creators may divert or anger, but it cannot enlighten.
The theatre is the best way of showing the gap between what is said and what is seen to be done, and that is why, ragged and gap-toothed as it is, it has still a far healthier potential than some poorer, abandoned arts.
