The Notion of κοινὴ αἴσθησις and Its Implications in Michael of Ephesus

Abstract

The paper examines three innovative issues in the Byzantine commentator which seem to reflect his own views on the common sense power. First, he perceives a gap in Aristotle’s explanation of the double nature of representational images. He points to the common sense power as the factor responsible for our ability to connect representational images to things represented by them. This kind of activity is called additional perception. Second, the identification of the common sense power with touch can be explained with reference to the thesis that animal life is a life of perception and touch is the principle of this life. It may lead to the conclusion that the basic pattern of all sense perception is to be equated with the general way that touch works. Third, Michael endorses the view that the regulative force of the common sense power extends to the ability to stop the individual senses working altogether, as it is clear from the explanation of sleep. In this process, the role of sense organs—both those of the individual senses and the first sense organ—is especially important, which—along with other observations—allows us to conclude that the Byzantine commentator is committed to hylomorphic explanations.
