The purpose of this paper is to identify the upholders of the thesis reported by Plutarch, De Stoicorum repugnantiis 23, aimed to reject Stoic determinism. A brief introduction will be devoted to the relationship between this text and the more general context of the Stoic philosophy. Then, I will take into account the objection against Stoic determinism raised by some anonymous philosophers: according to it, causal determinism would be inconsistent with the choice among indistinguishables. Chrysippus replied that if that choice (...) were not determined, it would occur without causes; and this would be absurd. Then I will summarize the most likely hypotheses about the identification of Chrysippus’ opponents, and I will opt for Academics. Finally, I will try to conjecture the link between Plutarch’s passage and the debate among Stoics and Academics about indistinguishables, as we know it from other sources. (shrink)

Surprisingly little attention has been devoted to Musonius Rufus, a noted teacher and philosopher in first–century CE Rome, despite ample evidence for his impact in the period. This paper attempts to situate Musonius in relation to his philosophical predecessors in order to clarify both the contemporary status of the Stoic tradition and the value of engaging with the central figures of that school’s history. I make the case for seeing Cleanthes as a particularly prominent predecessor for Musonius and reaffirm the (...) importance of framing his philosophical commitments in the context of the Stoic tradition. On this latter point, I attempt to connect Musonius’ perspective on askesis and moral development with that of Posidonius (and Seneca). In doing so, I push back against the sometimes overly schematic intellectualism attributed to Stoic ethics generally. (shrink)
