Chapter 2 considers how Cicero responded to the model of the body politic proposed by Catiline. Rejecting the head of state metaphor, his oratory describes a civic healer capable of diagnosing and curing the ills of the Republic. This idea drew upon a well-established moralizing tradition that identified vice as a contagion that had infected the res publica. Whereas Varro, Sallust, and Lucretius employed such imagery to indict Rome’s governing class for its ambitio and avaritia, Cicero used it to justify the extralegal execution of the Catilinarian conspirators. Although he sought to protect a constitution under threat, his medically inspired language helped legitimize violence as a tool of political engagement. Identifying Clodius and his allies as new malignancies in need of amputation, he contributed to a corrosive cycle of civic conflict that culminated in Pompey’s sole consulship and Caesar’s dictatorship, two constitutional innovations justified as curative remedies. In the end, his rhetoric proved susceptible to appropriation by those less invested in collegial governance than he.
