Gilbert Ryle

Gilbert Ryle (19 August 1900 – 6 October 1976) was a British philosopher. Today, he is mostly known for his critique of Cartesian dualism, which he called "ghost in the machine." He was a f British ordinary language philosophers who shared Ludwig Wittgenstein's approach to philosophical problems.
Some of Ryle's ideas in philosophy of mind have been called behaviourist. In his best-known book, "The Concept of Mind" (1949), he writes that the "general trend of this book will undoubtedly, and harmlessly, be stigmatised as 'behaviourist'." Having studied the philosophers Bernard Bolzano, Franz Brentano, Alexius Meinong, Edmund Husserl, and Martin Heidegger, Ryle suggested that the book instead "could be described as a sustained essay in phenomenology, if you are at home with that label."
