Vagueness and Kataleptic Impressions


tamer nawar


Clear and Distinct Perception in the Stoics, Augustine, and William of Ockham


The Stoic theory of kataleptic impressions looks different once we attend to their analysis of the Sorites Paradox. In defending this view, I reject the long-standing assumption that the Stoics develop their theory by focusing on sensory impressions. The Stoic approach to vagueness shows, for example, that non-sensory impressions can be seemingly indistinguishable by belonging to a series. It also draws attention to an understudied dimension of Stoic theory: in aiming to assent only to kataleptic impressions, one aims to avoid not only assent to false impressions, but also assent to those that are neither true nor false.

There is a long history of philosophers granting a privileged epistemic status to cognition of directly present objects. In this paper, I examine three important historic accounts which provide different models of this cognitive state and its connection with its objects: that of the Stoics, who are corporealists and think that ordinary perception may have an epistemically privileged status but who seem to struggle to accommodate non-perceptual cognisance; that of Augustine, who thinks that incorporeal objects are directly present to us in ‘intellectual perception’ and that, by way of contrast, ordinary sense-perception does not have a privileged epistemic status; and that of William of Ockham, who allows for action at a distance and is fairly generous about what counts as being directly present.
