Interface Design - Aristotle's Definition of Theater

Aristotle's definition of theater is not necessarily, I think, a direct quote from Aristotle. There is kind of some Aristotelian language there, which we're going to learn about very, very soon. Brenda Laurel says that interface design should concern itself with representing whole actions with multiple agents. She doesn't have a super robust theory of it, but she's trying to think, what is it? We know that theater is entirely artifice when we go to see it, right?
