Cicero’s De Officiis is the only surviving extended Stoic-style treatment of practical deliberation, offering guidance on what counts as well-judged decision-making. This chapter explores two questions raised by this feature of the work: (1) what is the general form of Stoic thinking on valid practical deliberation? (2) how far does Cicero’s De Officiis reflect the Stoic view of deliberation? On the first question, after considering recent scholarly discussions which stress the importance for Stoic deliberation of gaining advantages (‘preferable indifferents’), the chapter highlights the relevance for Stoic thought of a modern virtue ethical treatment of deliberation, which stresses the criterial role of virtue. On the second question, the chapter brings out how the structure and argumentation of De Officiis reflect the Stoic conception of deliberation, as presented here (that is, as centred on virtue).
