Cicero (106— 43 BCE)

In many ways, M. Tullius Cicero ‘translated’ Greek philosophy into Roman culture. His works reveal an active engagement in the philosophical schools of the Hellenistic and Roman period, as well as an appreciation for the active life of the orator and politician. Nowhere was his engagement with the life of philosophy more evident than in his Discussions at Tusculum. In this work he sets out his objections to Epicureanism and his affirmation of the basic Stoic ideal.

  • In theory, an Academic Skeptic
    • There are only probabilities
  • In practice, a Stoic
    • Our life and laws should model natural law

Selected Works

  • Philosophical On the State, On Laws, Horensius, Discussions at Tusculum, Laelius: On Friedship, On Duties(See excerpts relating to a Stoic based case analysis).
  • On Rhetoric On Invention (Rhetorica), On the Orator, the Divisions of Oratory, Topica (Methods of Drawing Conclusions)
  • See excerpts from the Routledge Encyclopedia of Philosophy article on Cicero. In ethics, contemporary interest in Cicero was sparked by Jonsen and Toulmin’s revival of case-based moral reasoning (casuistry) and the value of returning to Circero’s rhetorical writings such as On Invention.
