Nonperceptual Kataleptic Impressions in Stoicism

The kataleptic impression—an impression that is, in some special way, “true and such as could not be false”—is at the core of Stoic epistemology. Since Gisela Striker’s groundbreaking work on the criterion of truth, the dominant view among scholars is that the Stoics restricted kataleptic impressions to certain perceptual impressions. I argue that the Stoics in fact countenanced nonperceptual kataleptic impressions and explain how they thought nonperceptual impressions can meet the definition of the kataleptic impression.
