Abstract

A familiar interpretation of the Stoic doctrine of the πάθη runs as follows: The Stoics claim the πάθη are impulses. The Stoics take impulses to be causes of action. So, the Stoics think the πάθη are causes of action Premise is uncontroversial, but the evidence for needs to be reconsidered. I argue that the Stoics have two distinct but related conceptions of ὁρμή – a psychological construal and a behavioural construal. On the psychological construal is true, but there is strong evidence that is true only on the behavioural construal. That is, when the Stoics classify πάθη as impulses they are thinking of them not as impulses to act, but as cases of action in their own right.
