The basis of drama is... the struggle of the hero towards a specific goal at the end of which he realises that what kept him from it was, in the lesser drama, civilisation and, in the great drama, the discovery of something that he did not set out to discover but which can be seen retrospectively as inevitable.
David MametHere's what happens in a play. You get involved in a situation where something is unbalanced. If nothing's unbalanced, there's no reason to have a play. If Hamlet comes home from school, and his dad's not dead and asks him if he's had a good time, it's boring. But if something's unbalanced, it must be returned to order.
David MametA dramatic experience concerned with the mundane may inform but it cannot release; and one concerned essentially with the aesthetic politics of its creators may divert or anger, but it cannot enlighten.
