If the work of art is good enough, it must not be criticized for its theme. I don't think it can be argued.

If a man writes a brilliant enough play in praise of something that is universally loathed, the play, if it is good and well enough written, should not be knocked down because of its approach to its subject.

Influence is a matter of selection - both acceptance and rejection.

Art should never try to be popular.

Audiences and, to a large extent, critics who want less from theater than it is possible for it to give. If everybody's encouraged to want less, you'll end up with less.

I have learned that neither kindness or cruelty by themselves, or independent of each other, create any effect beyond themselves.

I don't pay much attention to how the plays relate thematically to each other. I think that's very dangerous to do, because in the theater one is self-conscious enough without planning ahead or wondering about the thematic relation from one play to the next. One hopes that one is developing, and writing interestingly, and that's where it should end, I think.
