Abstract

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.
