Many audiences all over the world will answer positively from their own experience that they have seen the face of the invisible through an experience on the stage that transcended their experience in life. They will maintain that Oedipus or Berenice or Hamlet or The Three Sisters performed with beauty and with love fires the spirit and gives them a reminder that daily drabness is not necessarily all.
It is because the public are a mass -- inert, obtuse, and passive -- that they need to be shaken up from time to time so that we can tell from their bear-like grunts where they are -- and also where they stand. They are pretty harmless, in spite of their numbers, because they are fighting against intelligence.
My conception of the audience is of a public each member of which is carrying about with him what he thinks is an anxiety, or a hope, or a preoccupation which is his alone and isolates him from mankind; and in this respect at least the function of a play is to reveal him to himself so that he may touch others by virtue of the revelation of his mutuality with them. If only for this reason I regard the theater as a serious business, one that makes or should make man more human, which is to say, less alone.
The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.
