Descartes's classical statement of the view that the human person consists of two individual substances, the body and the soul, has often been attacked, and has been attacked from various points of view. Many of these attacks, however, so far from rejecting what is usually known as Cartesian dualism, have merely launched the same doctrine under a new rig. They have distinguished between mental and physical objects, processes and cognitions (between ideas and material things, sensation and introspection, and so forth); they have distinguished mental from physical language by the application of one criterion of intentionality or another; they have distinguished reasons from causes; they have distinguished the body as an object in the world from the body as an embodied subject.
