Gilbert Ryle and the Map of the Mind

Gilbert Ryle (1900-1976) was a British philosopher of mind and language best known for his book The Concept of Mind. He developed a novel argument against Cartesian dualism, which he called “the doctrine of the ghost in the machine”—the idea that our minds and bodies are separate substances. Ryle introduced a new term for the problem with this argument: Descartes was making a “category mistake.” But what exactly is a category mistake, and how bad is it to make one? If Cartesian dualism is false, what is the relationship between our minds and our bodies? And what does it have to do with the distinction between “knowing-how” and “knowing-that”? Josh and Ray turn their minds to Michael Kremer from the University of Chicago, author of “The Development of Gilbert Ryle’s Concept of Knowledge.”
