Republican Virtues: Merits and Morals in Polybius’ Constitutional Analysis of the Histories, Book 6

John Adams asserted that the historical summation of republican political thought can be found in one writer: Polybius of Megalopolis. More clearly than any other, Polybius articulated those qualities that define good statesmen and citizens and make republics strong and successful. This article will examine this claim by bringing new historical analysis to Book 6 of Polybius’ Histories in order to identify the republican virtues important to Polybius. Polybius believed that Rome survived its early defeats in the Second Punic War and emerged triumphant over all of its enemies due to a unique combination of morals and merits that characterized good statesmen and strong republics. These extended deeper than political institutions and into the social fabric that bound the Roman people together and defined their relationships with one another, both in their homes as citizens and on campaign as soldiers. This article will work through Polybius’ analysis and show how Rome’s constitution used political institutions to suppress civic vices; armies in the field to cultivate civic service, sacrifice, and skill; military camps to shape public notions of duty, honor, and shame; and Roman families—as exemplified in public funerals—to habituate and showcase personal and civic virtues.
