Rene Descartes holds a dualist view that the mind and body are two totally separate entities. In response to this Gilbert Ryle has published an article showing that the argument, and its premises, of Descartes' Metaphysical Doctrine are incorrect. He does not show the premises, themselves, to be individually false, but instead shows that Descartes has simply made an error in his conceptualizations of the mind and body. In this paper I will show that Ryle's analysis of the Metaphysical Doctrine, and it faults, is correct. In addition, his arguments against the premises of the Doctrine are accurate and effective.

Ryle believes that Descartes has simply made a 'category error' in trying to explain the relationship between the mind and the body. A "category error" occurs when an individual is unable to grasp a larger concept and understand simple terminology. For example, a person may look at a closet full of clothes, yet still be unable to understand the idea of the wardrobe. He may see all the shirts and pants hanging, and all the shoes stacked up, but still be unable to see where the wardrobe is. This person has not grasped the concept that the wardrobe is not a separate, tan

5. Therefore, the mind and body can't be one thing, so they must be distinct.

Descartes has made a similar 'category error' in assuming that the mind and body must be separate items. Ryle shows that although the two cannot be spoken of in the same manner, they are still interrelated: "Because, as is true, a person's thinking, feeling, and purposive doing cannot be described solely in the idioms of physics, chemistry and physiology, therefore they must be described in counterpart idioms" (pp.54).

4. Divisibility and indivisibility are incompatible properties.

1. No one thing can have incompatible, essential properties.

ve any mechanical laws governing it (pp.54) Ryle believes this to be false because you can't compare the properties of, or the rules governing, items from two different categories. An individual orange does not fall into the same category as a group of oranges does, although they are related. The same holds true for the mind and the body: since they do not belong to the same category, they cannot be judged, or spoken of, in the same manner.
