In fact, the belief that neurophysiology is even relevant to the functioning of the mind is just hypothesis. Who knows if we’re looking at the right aspects of the brain at all. Maybe there are other aspects of the brain that nobody has even dreamt of looking at yet. That’s often happened in the history of science. When people say that the mental is the neurophysiological at a higher level, they’re being radically unscientific. We know a lot about the mental from a scientific point of view. We have explanatory theories that account for a lot of things. The belief that neurophysiology is implicated in these things could be true, but we have every little evidence for it. So, it’s just a kind of hope; look around and you see neurons; maybe they’re implicated.
