Gilbert Ryle (1900–1976) was a British philosopher who served as Waynflete Professor of Metaphysical Philosophy at Oxford. His 1949 book *The Concept of Mind* attacked Cartesian [[Dualism]], famously dismissing it as the "ghost in the machine"—the mistaken view that mind and body are separate substances. Ryle argued this commits a "category mistake": treating mental concepts as if they named hidden inner processes rather than dispositions to behave.
Ryle's work laid groundwork for [[Functionalism]] and ordinary language philosophy. He influenced [[Daniel Dennett]] and the broader move away from introspectionist psychology toward behavioral and functional analyses of mind. His concept of "knowing how" vs "knowing that" remains influential in epistemology and cognitive science.
