A good television repair person can look at  the particular distortion of the picture or sound of a television set and  tell us exactly what is wrong with it and which parts must be replaced  to make the set work properly again. No one would see this as proof  that the set itself was responsible for the programs we see when we  turn it on. Yet, this is precisely the kind of argument mechanistic sci-  ence offers for “proof” that consciousness is produced by the brain.
