The dogma of the Ghost in the Machine ... maintains that there exist both bodies and minds; that there occur physical processes and mental processes; that there are mechanical causes of corporeal movements and mental causes of corporeal movements.
Gilbert RyleWhen the epistemologists' concept of consciousness first became popular, it seems to have been in part a transformed application of the Protestant notion of conscience."Consciousness" was imported to play in the mental world the role played by light in the mechanical world.
Gilbert RyleOnly through the medium of the public physical world can the mind of one person make a difference to the mind of another. The mind is in its own place and in each of us lies an inner life, 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
