De Officiis (On Duties or On Obligations) is a political and ethical treatise by the Roman orator, philosopher, and statesman Marcus Tullius Cicero written in 44 BC. The treatise is divided into three books, in which Cicero expounds his conception of the best way to live, behave, and observe moral obligations. The work discusses what is honorable (Book I), what is to one's advantage (Book II), and what to do when the honorable and one's private interest apparently conflict (Book III). In the first two books Cicero was heavily influenced by the Stoic philosopher Panaetius, but wrote more independently for the third book. Though under-appreciated in modern scholarship and philosophy curriculums, De Officiis is one of the most famous philosophical works ever written. In addition to being a central component of liberal education for centuries, the work was held in high regard among many prolific philosophers and statesman including Augustine, Thomas Aquinas, Hugo Grotius, Montesquieu, Voltaire, and the American Founding Fathers. De Officiis, along with Xenophon's Cyropaedia, are considered among the foundational works in the genre of the mirrors for princes, now most famously associated with Machiavelli's The Prince.


De Officiis was written in October–November 44 BC, in under four weeks.[1] This was Cicero's last year alive, and he was 62 years of age. Cicero was at this time still active in politics, trying to stop revolutionary forces from taking control of the Roman Republic. Despite his efforts, the republican system failed to revive even upon the assassination of Caesar, and Cicero was himself assassinated shortly thereafter.


De Officiis is written in the form of a letter to his son Cicero Minor, who studied philosophy in Athens. Judging from its form, it is nonetheless likely that Cicero wrote with a broader audience in mind. The essay was published posthumously.

Although Cicero was influenced by the Academic, Peripatetic, and Stoic schools of Greek philosophy, this work shows the influence of the Stoic philosopher Panaetius.[2][3] Panaetius was a Greek philosopher who had resided in Rome around eighty years previously.[4] He wrote a book On Duties (Greek: Περὶ Καθήκοντος) in which he divided his subject into three parts but had left the work unfinished at the third stage.[4] Although Cicero draws from many other sources, for his first two books he follows the steps of Panaetius fairly closely.[5] The third book is more independent,[5] and Cicero disclaims having been indebted to any preceding writers on the subject.[6] Michael Grant tells us that "Cicero himself seems to have regarded this treatise as his spiritual testament and masterpiece."[7]

Cicero urged his son Marcus to follow nature and wisdom, as well as politics, and warned against pleasure and indolence. Cicero's essay relies heavily on anecdotes, much more than his other works, and is written in a more leisurely and less formal style than his other writings, perhaps because he wrote it hastily. Like the satires of Juvenal, Cicero's De Officiis refers frequently to current events of his time.


From a German edition – 1531

The work discusses what is honorable (Book I), what is expedient or to one's advantage (Book II), and what to do when the honorable and expedient conflict (Book III). Cicero says they are the same and that they only appear to be in conflict. In Book III, Cicero expresses his own ideas.[8]

Book One[edit]

The first book treats of what is honorable in itself.[6] He shows in what true manner our duties are founded in honor and virtue.[6] The four constituent parts of virtue are truth, justice, fortitude, and decorum, and our duties are founded in the right perception of these.[6]

161 Conclusion

Book Two[edit]

The second book enlarges on those duties which relate to private advantage and the improvement of life.[6] The book focuses on political advancement, and the means employed for the attainment of wealth and power.[6] The honorable means of gaining popularity include generosity, courtesy, and eloquence.[6]

Book Three[edit]

The third book discusses the choice to be made when there is an apparent conflict between virtue and expediency.[6] True virtue can never be put in competition with private advantage.[6] Thus nothing should be accounted useful or profitable if not strictly virtuous, and there ought to be no separation of the principles of virtue and expediency.[6]

Cicero proposes some rules for cases of doubt, where seeming utility comes into competition with virtue.[6] He examines in what situations one may seek private gain with honour.[6] He takes his examples from Roman history, such as the case of Marcus Atilius Regulus who was released by the Carthaginians to negotiate a peace, advised the Roman Senate to reject the proposals, and fulfilled his oath by returning to Carthage.[6]


De Officiis has been characterized as an attempt to define ideals of public behavior.[9] It criticizes the recently overthrown dictator Julius Caesar in several places, and his dictatorship as a whole. Cicero claims that the absence of political rights corrupts moral virtues. Cicero also speaks of a natural law that is said to govern both humans[10] and gods alike.[11]


The work's legacy is profound. Although not a Christian work, St. Ambrose in 390 declared it legitimate for the Church to use (along with everything else Cicero, and the equally popular Roman philosopher Seneca, had written). It became a moral authority during the Middle Ages. Of the Church Fathers, St. Augustine, St. Jerome and even more so St. Thomas Aquinas, are known to have been familiar with it.[12] Illustrating its importance, some 700 handwritten copies remain extant in libraries around the world dating back to before the invention of the printing press. Though this does not surpass the Latin grammarian Priscian's 900 extant handwritten copies, it places De Officiis far above many classical works. Following the invention of the printing press, De Officiis was the third book to be printed—third only to the Gutenberg Bible and Donatus's "Ars Minor", which was the first printed book.[13]

Petrarch, the father of humanism and a leader in the revival of Classical learning, championed Cicero. It is suspected that Machiavelli's The Prince is at least in part meant to be a direct refutation of Cicero's De Officiis. is Several of his works build upon the precepts of De Officiis.[14] Prince Peter, Duke of Coimbra, member of the Order of the Garter, translated the treatise to portuguese in 1437, signal of the wide spread of the work in medieval courts.[15] The Catholic humanist Erasmus published his own edition in Paris in 1501. His enthusiasm for this moral treatise is expressed in many works.[14][16] The German humanist Philip Melanchthon established De Officiis in Lutheran humanist schools.[14]

Henry VIII's childhood copy of De Officiis, bearing the inscription "Thys boke is myne" in his hand, from the collection of the Folger Shakespeare Library.

T. W. Baldwin said that "in Shakespeare's day De Officiis was the pinnacle of moral philosophy".[17] Sir Thomas Elyot, in his popular Governour (1531), lists three essential texts for bringing up young gentlemen: Plato's works, Aristotle's Ethics, and De Officiis.[18]

In the 17th century it was a standard text at English schools (Westminster and Eton) and universities (Cambridge and Oxford). It was extensively discussed by Hugo Grotius and Samuel von Pufendorf.[19] Grotius drew heavily on De officiis in his major work, On the Law of War and Peace.[14] It influenced Robert Sanderson and John Locke.[19]

In the 18th century, Voltaire said of De Officiis "No one will ever write anything more wise".[20] Frederick the Great thought so highly of the book that he asked the scholar Christian Garve to do a new translation of it, even though there had been already two German translations since 1756. Garve's project resulted in 880 additional pages of commentary.

In 1885, the city of Perugia was shaken by the theft of an illuminated manuscript of De Officiis from the city's Library Augusta. The chief librarian Adamo Rossi, a well-known scholar, was originally suspected but exonerated after a lengthy administrative and judicial investigation. The culprit in the theft was never found. Suspicion fell on a janitor who a few years later became well-to-do enough to build for himself a fine house. The former janitor's house was nicknamed "Villa Cicero" by residents of Perugia.

The 2002 George Mason Memorial in Washington, D.C. includes De Officiis as an element of the statue of a seated Mason.

De Officiis continues to be one of the most popular of Cicero's works because of its style, and because of its depiction of Roman political life under the Republic.


  • ...and brave he surely cannot possibly be that counts pain the supreme evil, nor temperate he that holds pleasure to be the supreme good. (Latin: fortis vero dolorem summum malum iudicans aut temperans voluptatem summum bonum statuens esse certe nullo modo potest) (I, 5)
  • Not for us alone are we born; our country, our friends, have a share in us. (Latin: non nobis solum nati sumus ortusque nostri partem patria vindicat, partem amici) (I, 22)
  • Let us remember that justice must be observed even to the lowest. (Latin: Meminerimus autem etiam adversus infimos iustitiam esse servandam) (I, 41)
  • Let arms yield to the toga, the laurel defer to praise. (Latin: cedant arma togae concedat laurea laudi) (I, 77)
  • It is the function of justice not to do wrong to one's fellow-men; of considerateness, not to wound their feelings; and in this the essence of propriety is best seen. (Latin: Iustitiae partes sunt non violare homines, verecundiae non offendere, in quo maxime vis perspicitur decori) (I, 99)
  • Is anyone unaware that Fortune plays a major role in both success and failure? (Latin: Magnam vim esse in fortuna in utramque partem, vel secundas ad res vel adversas, quis ignorat?) (II, 19)
