Abstract

The centrepiece of Cicero's De re publica is a discussion of justice. This discussion, which evokes the theme of the Platonic dialogue after which it was named, consists of a set of three speeches. It begins with a speech opposing justice, placed in the mouth of L. Furius Philus and alleged by him to be modelled on the second of a pair of speeches for and against justice delivered in Rome in 155 B.C. by the Greek Academic philosopher Carneades. Philus' speech lays the dialectical foundation for the two subsequent speeches, a defence of justice as the prerequisite for government by C. Laelius, and an explanation of its role in various forms of government by Scipio Aemilianus.
