Crane's Citation of Wittgenstein
Wittgenstein is said to have asked his students why people used to think that the sun went around the earth. One replied: ‘because it looks as if the sun goes around the earth.’ To which Wittgenstein is said to have responded: ‘and how would it look if the earth went around the sun?’ The obvious answer—‘exactly the same!’—can be given to the analogous question about mind and brain: why did people use to think that the mind was not the brain? Because it seems as if the mind is not the brain? And how would it seem if the mind were the brain?
