Augustine and the Cognitive Cause of Stoic Preliminary Passionsi ( Propatheiai )

Augustine made a significant contribution to the history of philosophical accounts of affectivity which scholars have not yet noticed. He resolved a problem with the Stoic theory as it was known to him: the question of the cognitive cause of "preliminary passions" ( propatheiai ), reflex-like affective reactions which must be immediately controlled if a morally bad emotion is to be avoided. He identified this cognitive cause as momentary doubt , as I demonstrate by citing passages from sermons spanning twenty-seven years in which Augustine consistently used a particular set of scriptural images and phrases as precise analogies for mental and affective states.
