A theatre which honours its audience will demand of its writers that they write in hazard of their consciences, for writers are paid to think dangerously, they are explorers of the imagination, the audience expects it of them. If they think safely, what is the virtue of them? Do you want to pay £10 to be told what you knew already? That is theft. Do you want to agree all the time? That is flattery, and the audience is always flattered, which is why it has become so sleek.
An honoured audience will quarrel with what it has seen, it will go home in a state of anger, not because it disapproves, but because it has been taken where it is reluctant to go. Thus morality is created in art, by exposure to pain and illegitimate thought.
