De Officiis is a 44 BC treatise by Marcus Tullius Cicero 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, what is to one's advantage, and what to do when the honorable and private gain apparently conflict. For the first two books Cicero was dependent on the Stoic philosopher Panaetius, but wrote more independently for the third book.
