Does Consciousness Perform a Function Independently of the Brain?

Even if all of the content of conscious experience is encoded in the brain, there is a considerable difference between the view that consciousness does independent processing and the view that it does not. If all processing is done by the brain, then conscious experience is unnecessary and irrelevant to behavior. If consciousness performs a function, then its association with particular aspects of brain processing reflect its functional use in determining behavior. However, if consciousness does perform a function, it cannot be described entirely by known physical laws. Rather, even if the content of conscious experience follows physical encoding in the brain, consciousness must then be governed in part by a principle which is different from any known physical principle.
