Cicero

Marcus Tullius Cicero (106–43 BCE) was a Roman statesman, orator, and philosophical writer, a leading political actor of the late Roman Republic and the author of the first surviving attempt to articulate a philosophical rationale for republicanism¹^•². Around a dozen of his philosophical works survive, alongside speeches, treatises on rhetoric, and a large collection of letters¹. His writings shaped Western legal and political thought for two millennia, and he is still quoted, and argued over, today³^•⁴.

Political career

Cicero rose through Roman politics without the advantage of birth. As the most famous homo novus of Roman public life, he came from a minor provincial landowning family rather than the great clans of hereditary nobility⁵. His rhetorical training was laid down early: the principles of oratory were impressed on him by Molo the Rhodian, whose reputation as a forensic speaker matched his skill as a teacher, and Cicero practiced declamation daily, more often in Greek than in Latin⁷. He was elected consul for 63 BCE, a contest for which primary sources survive including letters to Atticus, extracts from two speeches, and his own "Short Guide to Electioneering"⁶.

His provincial command came by lot: when a law of Pompey's third consulship was enacted to curb the bribery and intrigue by which magistrates sought wealthy governorships, Cicero's name was drawn and he was assigned Cilicia, to which Pisidia, Pamphylia, some districts of Cappadocia north of Mount Taurus, and the island of Cyprus were annexed⁷.

His speeches and letters are themselves of political and philosophical interest, reworking the evaluative vocabulary of Roman law and politics to serve his shifting purposes. A critical assessment by Ingo Gildenhard concludes that in his rhetoric Cicero "consistently refused to recognize the positions of his adversaries as genuine political positions" and challenged their standing as senatorial peers, Roman citizens, or even human beings⁵.

Political philosophy

Malcolm Schofield, a professor emeritus of ancient philosophy at the University of Cambridge, reads Cicero's theoretical works as an exploration of central political concepts: freedom and equality, governance, the law, cosmopolitanism together with imperialism, the virtues of republican life, and how ethical choices are made in political affairs. Schofield situates these works in the context of a fracturing traditional Roman political order, while noting both the continuing attraction of Cicero's conceptual landscape and some of its limits as a response to the crisis engulfing Rome².

Natural law. At the heart of Cicero's political theory lies a novel conception of natural law: realist, in that the natural law is an objective part of the world discoverable by reason, yet novel against Greek antecedents in that it does not incorporate a substantive conception of the highest good⁸. In De re publica, Scipio asserts that there is a universal natural law with authority over any civil law, so that what carries ultimate moral weight is the judgment of the wise person who understands it rather than the decree of the Roman people (1.27); the dialogue's closing Dream of Scipio, the most famous excerpt in all of Cicero's philosophy, survived only because it came down in a separate manuscript tradition¹⁰. In the academic-skeptic mode of his rhetorical works, the speech for justice adopts Stoic themes: "true law is right reason, consonant with nature", and there is "one eternal and unchangeable law"⁵.

Law and eloquence. Cicero's practical relationship to law was that of an advocate, and a chapter of Cicero the Advocate argues that his courtroom use of law is best explained by three factors: the nature of public pleading; the many uncertainties and obscurities inherent in Roman law of the first century BCE, which left space for genuine dispute; and his contention, expressed most fully in the De Oratore of 55 BCE, that knowledge of law per se mattered less than eloquence in winning cases¹¹. Later scholarship on Cicero as a legal thinker frames the question as a paradox: anyone interested in him as a legal thinker and in his importance for the development of Roman law faces a somewhat paradoxical situation, given that he wrote as advocate and outsider rather than jurist¹².

Philosophy and method

Philosophy was a lifelong passion. One of Cicero's stated purposes in writing it was to bring the best of the Greek philosophical inheritance to wider Roman attention, and modern scholarship long valued his work chiefly as a report on the schools of his day: Stoicism, Epicureanism, and Academic skepticism¹. He is now increasingly studied as a philosopher in his own right, partly because of the creative way he engages with predecessors¹.

His method was deliberately skeptical. He set himself against the "dogmatic" schools of his time, in particular Epicureanism and Stoicism, where dogmatism means doctrines that their advocates treat as settled truth rather than positions argued without support¹³. The Academica, which survives in a rather misshapen state containing portions of two different editions, presents the epistemological viewpoint of the skeptical Academy and so serves as a defense of the method he employs in much of his philosophical writing¹⁴. Its recent critical edition, prepared by Tobias Reinhardt for the Oxford Classical Texts, was the first new edition of the text since 1908¹⁵.

Influence

Mortimer N. S. Sellers, a professor at the University of Baltimore School of Law, calls Cicero "the father of modern law and politics" and argues that his influence, significant throughout subsequent European history, was never greater than in the emergence of modernity and the development of modern law and constitutional government³. On representation, Gary Remer argues against the view that political representation is a purely modern phenomenon: in De oratore and De republica Cicero describes his ideal orator-statesman with terms such as procurator, auctor, tutor, dispensator, and vilicus that suggest representation, and the characteristics he assigns the orator parallel those modern theorists such as Edmund Burke and John Stuart Mill associate with the representative¹⁶.

Cicero also made himself a subject of the historical record. In 59 BC he wrote privately to his close friend Titus Pomponius Atticus that he worried "far more what the judgement on me will be in a 1,000 years time than what the trolls are saying today"; more than 2,000 years later he is still being quoted⁴.

Afterlife and modern reception

Cicero's account of the Republic's end remains influential in how later ages imagine Rome. Donna Zuckerberg, a classics scholar who studies Silicon Valley culture, notes that Cicero strongly influenced how we picture the late Roman Republic and, motivated partly by self-definition, sought to portray Rome as a meritocracy in which exceptionally gifted men such as himself would attain the highest positions; she contends that this story glosses over the entrenched power structures that made success easier for men with wealth and connections.¹⁷

His last act fixed the terms of his reputation. After Julius Caesar was assassinated in 44 BCE, he judged it a civic duty to speak out against the threat to the republic posed by Mark Antony, denouncing Antony as a tyrant in the speeches called the Philippics⁹. Textual scholarship on him continues: Robert Kaster's Oxford Classical Text edition of the Tusculan Disputations, which presents in dialogue form Cicero's views on the fear of death, the endurance of pain, and virtue as the basis of the best human life, is the first new edition of that work in over forty years¹⁸.
