The document discusses the debate between those who defend ancient Greek and Roman playwrights and those who defend modern English playwrights. It outlines the three classical unities that ancient plays followed - unity of time, place, and action - and how modern English plays often violate these unities, covering long periods of time, multiple locations, and containing sub-plots. It also notes how the ancients focused on a single, complete action in their plays and represented human passions to both delight and instruct audiences.
