Abstract
The ancient Stoics insisted that everything happens by fate, and repeatedly defended themselves against objections from their Academic, Epicurean, and Peripatetic opponents to the effect that this thesis would entail that our actions are not “up to us”. In both their determinism and their compatibilism, the Stoics strike readers today as extremely modern in their philosophical orientation, and their concerns seem continuous with those expressed in modern debates about the compatibility of free will and determinism.
