If the audience is made to do not enough work, they resent it without knowing it. Too much and they get lost. There's a perfect pace to be found. And a perfect place that is different for every line of the play.
Tom StoppardHe's never known anything like it! But then, he has never known anything to write home about, so this is nothing to write home about.
Tom StoppardPoetical feelings are a peril to scholarship. There are always poetical people ready to protest that a corrupt line is exquisite. Exquisite to whom?
