Theophrastus on Plato’s Theory of Vision

Abstract

Abstract In paragraphs 5 and 86 of the De sensibus Theophrastus gives a brief report of Plato’s views on the sense of vision and its object, i. e. colour, based on the Timaeus. Interestingly enough, he presents the Platonic doctrine as a third alternative to the extramission and intromission theories put forward by other ancient philosophers. In this article I examine whether or not Theophrastus’ account is impartial. I argue that at least some of his distortive departures from the Platonic dialogue are due to his Aristotelian inheritance, even though they do not always represent Aristotle’s expressed views.
