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 playwrights 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. The document argues that the ancients were superior because their plays had a single, complete action, unlike many modern English plays.
