A study of fundamental questions of political theory framed in the context of the institutions and writings of ancient Greek and Roman thinkers, from the classical period into late antiquity and the spread of Christianity. Topics include the meaning of justice in Plato's Republic, the definition of the citizen in Aristotle's Politics, Cicero's reflections on the purpose of a commonwealth, and Augustine's challenge to those reflections and to the primacy of political life at all in light of divine purposes. We consider both the primary texts and secondary literature debates to equip students with a working mastery of this tradition.
