For my part, I confess I seldom listen to the players: one has so much to do, in looking about and finding out one's acquaintance, that, really, one has no time to mind the stage. One merely comes to meet one's friends, and show that one's alive.
I want to give the audience a hint of a scene. No more than that. Give them too much and they won't contribute anything themselves. Give them just a suggestion and you get them working with you. That's what gives the theater meaning: when it becomes a social act.
By whatever means it is accomplished, the prime business of a play is to arouse the passions of its audience so that by the route of passion may be opened up new relationships between a man and men, and between men and Man. Drama is akin to the other inventions of man in that it ought to help us to know more, and not merely to spend our feelings.
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.
