Abstract

ABSTRACT The problem of “scotopic vision”, or vision under conditions of partial or total darkness, is one of the most enigmatic and least studied topics in Aristotelian psychology. In the article we present the exegesis of Averroes on this matter. We point out a dificulty that arises in the Great Commentary around some terms used to designate the obscurity in the whole of the theory. We propose as a solution a moderate interpretation of the matter, in accordance with the “principle of economy” and the traditional exegesis of the commentators.
