The Importance of Beliefs in the Brain

There are a couple of theories of mind that do say that the mental is not causally operative. One is limitivism, which just says the mind doesn't exist at all. Another is called epiphenomenalism, which suggests that the mind is an emergent property but it doesn't have any causal powers. They're just sort of not the same emergent properties out of it because it's just not organized the way our brains are. And so we know that, you know, physical processes can produce true beliefs in the brain.
