In this paper we examine the genealogy and transmission of moral duty in Western ethics. We begin with an uncontroversial account of the Stoic notion of the kathēkon, and then examine the pivotal moment of Cicero’s translation of it into Latin as ‘officium’. We take a deflationary view of the impact of Cicero’s translation and conclude that his translation does not mark a departure from the Stoic ideal. We find further confirmation of our deflationary position in the development of the (...) notion of ‘duty’ in Germany between the 16th and 18th centuries. We examine Pufendorf’s critique of ancient eudaimonism and his appropriation of officium, and claim that it foreshadows Kant’s rejection of Garve’s Ciceronian ethics. We demonstrate the undeniable parallels between Kant’s Groundwork and Garve’s influential translation of Cicero’s De Officiis, thereby indicating a novel way in which we should understand Cicero’s contribution to the development of modern moral philosophy.

This provocative study presents philological, philosophical, and historical arguments that with the Greek term καθῆκον and its Latin equivalent officium the ancient Stoics invented a new concept that anticipated the modern notion of moral duty, for example, Pflicht in Kant. Scholars began to shift from translating kathēkon as "duty" to translating it as "appropriate or fitting action" in the late 1800s, according to Visnjic. The usage of the verb kathēkein in Greek literature prior to the Stoics suggests to him that (...) it described something prescribed by law, tradition, or decree. Visnjic argues that the Stoics did not conceive of kathekonta as rules of conduct but as prescriptions specific to situations. They held that there are some universal duties, like believing in the gods, believing that the gods are benevolent guardians of humanity, and being a good person, but that such duties offer no concrete, practical guidance for determining how to act. The most innovative contribution of this work is the collection and collation of pieces of practical advice scattered throughout extant sources to devise a four-stage process of deliberation. The two chapters on Kant seem comparatively cursory. On the whole, this book, at times daringly inventive, is occasionally unapologetically speculative. (shrink)

It is very difficult to get a clear picture of how the Stoic is supposed to deliberate. This paper considers a number of possible pictures, which cover such a wide range of options that some look Kantian and others utilitarian. Each has some textual support but is also unworkable in certain ways: there seem to be genuine and unresolved conflicts at the heart of Stoic ethics. And these are apparently due not to developmental changes within the school, but to the (...) Stoics’ having adopted implicitly incompatible solutions in response to different philosophical challenges. (shrink)
