The primary aim of this paper is to provide a new account of Descartes’s positive philosophical view on sensory perception, and to do so in a way that will establish a hitherto unnoticed continuity between his thought and that of his scholastic Aristotelian predecessors on the topic of sensory perception. I will argue that the basic framework of the scholastic Aristotelian view on sensory perception (as traditionally understood) is operative within Descartes's own view, and then reveal some insights on the issue of whether Descartes was a representationalist about sensory perception by critically examining one kind of representationalist reading of Descartes under the lens of my account. I will conclude by examining the implications that my view has for the proposed distinction between Descartes and the scholastics based on attributing representationalism to the former and direct-realism to the latter.

At the heart of Descartes’s theory of cognition is the act of perceiving an idea. However, it remains unclear what precisely an idea is, what the act of perceiving ideas amounts to, and how that act contributes to the formation of cognition under Descartes’s view. In this paper, I provide an account of perceiving ideas that clarifies Descartes’s notion of an idea and explains the fundamental role that the perceiving of ideas occupies in his theory of cognition. At the end of the paper, I will address an issue that arises regarding the objective reality of ideas and the unity of mind.
