Descartes', Sixth Meditation: The External World, ‘Nature’ and Human Experience

Abstract

The Sixth Meditation deals, as its title proclaims, with ‘the existence of material things, and the real distinction between the mind and body of man’. In this paper, I want to start by examining Descartes' argument for the existence of material things—for the existence of an ‘external’, physical world around us. Next, in section two, I shall use this argument concerning the external world to bring out an important general point about the ‘dialectical’ way in which Descartes presents his reasoning in the Meditations. This will lead me on to the third section of the paper, which will analyse the concept of ‘nature’ and the role it plays in Descartes' reasoning, particularly in the Sixth Meditation. And this in turn will bring me to the fourth and final part of the paper, which will focus on what is by general consensus the most fascinating part of the Sixth Meditation—Descartes' account of the relation between mind and body. What I shall try to do in this final section is to highlight a curious tension between Descartes' recognition of the facts of human experience on the one hand, and on the other hand his doctrine that we are essentially incorporeal or non-physical substances.
