Abstract

This paper aims to describe the Cartesian conception on the universals, as well as the way in which this conception could be related to the position developed by Locke in the Essay. Firstly, some considerations about the role of sensorial knowledge in Cartesian philosophy are analyzed. Secondly, some considerations about Locke’s conception of idea are reviewed. Then, the Cartesian concept of universal is reviewed considering his position in the Principia. Finally, Descartes’ and Locke’s view about universals are compared highlighting the role that both thinkers assign to the sensory experience in their theory of knowledge.
