The essay is concerned with justice in the Oresteia and the way the Oresteia contributes to the justice it celebrates. It begins by examining the place of tragedy in Athenian politics as a preface to an analysis of the trilogy's understanding of justice. That understanding is explored using two examples of fundamentally conflicting forces which are reconciled in the play to create a whole larger and more just than either force alone. The essay goes on to argue that the form of tragedy recapitulates and reinforces the substantive teachings on justice previously analyzed. Here four elements are considered: the balances between intelligence and passion, action and boundaries, political discourse and poetry, and the Euminides and Agamemnon.
