Qualities and sensory perception

Overview & Synopsis

This article describes the conception of sensory perception during the early modern period. It discusses David Hume's Treatise of Human Nature where he contrasted the ancient metaphysics of substantial forms and occult qualities with the metaphysics of the Moderns. The article argues that Hume was fundamentally correct and that the doctrine of secondary qualities is indeed a distinctively modern doctrine that captures something of the very essence of the new philosophical age.
