So too Plato was, in my view, a very unreliable Platonist. He was too much of a philosopher to think that anything he had said was the last word.
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
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 RyleThe 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 RyleContemporary 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.
Gilbert RyleIt 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.
