The Concept of Mind

Name: The Concept of Mind
Author: Gilbert Ryle

The Concept of Mind is a 1949 book by philosopher Gilbert Ryle, in which the author argues that "mind" is "a philosophical illusion hailing chiefly from René Descartes and sustained by logical errors and 'category mistakes' which have become habitual." The work has been cited as having "put the final nail in the coffin of Cartesian dualism" and has been seen as a founding document in the philosophy of mind, which received professional recognition as a distinct and important branch of philosophy only after 1950.

“Contemporary philosophers have exercised themselves with the problem of our knowledge of other minds. Enmeshed in the dogma of the ghost in the machine, they have found it impossible to discover any logically satisfactory evidence warranting one person in believing that there exist minds other than his own. I can witness what your body does, but I cannot witness what your mind does, and my pretensions to infer from what your body does to what your mind does all collapse, since the premises for such inferences are either inadequate or unknowable.”

“It is of first-rate importance to notice from the start that stupidity is not the same thing, or the same sort of thing, as ignorance. There is no incompatibility between being well-informed and being silly, and a person who has a good nose for arguments or jokes may have a bad head for facts.”

“The mind is its own place and in his inner life each of us lives the life of a ghostly Robinson Crusoe. People can see, hear and jolt one another’s bodies, but they are irremediably blind and deaf to the workings of one another’s minds and inoperative upon them.”

“Such in outline is the official theory. I shall often speak of it, with deliberate abusiveness, as "the dogma of the Ghost in the Machine." I hope to prove that it is entirely false, and false not in detail but in principle. It is not merely an assemblage of particular mistakes. It is one big mistake and a mistake of a special kind. It is, namely, a category mistake. It represents the facts of mental life as if they belonged to one logical type or category (or range of types or categories), when they actually belong to another. The dogma is therefore a philosopher’s myth.”
