The Origins of Cartesian Dualism.

In the recently discovered Cambridge manuscript, widely regarded as an early draft of Rules for the Direction of the Mind, Descartes does not describe the mind as a 'purely spiritual' force 'distinct from the whole body'. This has led some readers to speculate that Descartes did not embrace mind-body dualism in the Cambridge manuscript. In this article, I offer a detailed interpretation of Descartes's mind-body dualism in the established Charles Adam and Paul Tannery edition of Rules, and argue that, while differences between the Cambridge manuscript and the established version of Rules are significant, the relevant passages in the Cambridge manuscript preclude interpretation along both materialist and hylomorphic lines. I then offer an account of the development of Descartes's mind-body dualism between the Cambridge manuscript and the established version of Rules. What the Cambridge manuscript reveals is not Descartes before dualism, but rather Cartesian dualism in its barest form. [ABSTRACT FROM AUTHOR]
