Virgil Thomson, the great classical music critic, who was also a composer, but said that criticism was the only antidote he knew to pay publicity. Critics at their best are independent voices people take seriously their responsibility to see as many things as they can see, put them in the widest possible perspective, educate their readers, I really do think of myself as a teacher. Newspapers that don't carry arts criticism at all while not fulfill this function. And probably their arts journalism will be deprived as a result.

A critic should always strive to recapture the sense of wonder and surprise with which he first beheld a now-familiar work of art.

We are born into a vast room whose walls consist of a thousand doors of possibility. Each door is flung open to the world outside, and the room is filled with light and noise. We close some of the doors deliberately, sometimes with fear, sometimes with calm certainty. Others seem to close by themselves, some so quietly that we do not even notice.

Direction is the most invisible part of the theatrical art. It's not like the conductor in the symphony orchestra performance because he's standing in front of you waiving his arms. You now what he's doing. You don't know what the director is doing unless you know a lot about theater and even then you can only deduce it. You know it when you go to rehearsal. You really know it when they are rehearsing something of yours. I learned more in the rehearsals for The Letter than I have ever dreamed of know in the theater as a critic. If it doesn't make me a better critic, I'm an idiot.

The most important thing to remember is that the composer is a senior partner. You cannot force a subject on a composer if it doesn't inspire him. He has to take the lead, you are an enabler, and you are creating the enabling conditions under which he can write great music. Your words are secondary. Many librettists in opera collaborations in the past have forgotten this, or not known it, or refuse to accept it and tried to get out in front of the creative process and it just doesn't work that way.

If I ever see another Shakespeare production where somebody drives a Jeep on stage, I'm going to run screaming up the aisle. These tend to be matters of design. I mean, we're seeing a lot of - it's very common to see Shakespeare with automatic weapons, things like that. They are clichés. They're new clichés, but they are clichés. And they're provincial. It's not clever to do Henry V, and have everybody dressed in United Nations soldier's costumes anymore. I've seen that one too. That kind of thing irritates me.

There will be this mix of people like me who write for major national newspapers and amateur critics, practitioner critics, whose primary way of distributing what they talk about is through blogs and on the web. The line between professional and amateur criticism will become increasingly blurred. The problem here is that if you want to do this for a living, you have to be able to earn a living doing it.
