> which we can't get at using normal, scientific, physical observations of the world Why? This would make it unusual compared to every other process in biology and everything we actually do know about consciousness. We know that most of the faculties we subjectively attribute to the conscious experience are rooted in physical biology (reasoning, instinct, emotion, memory etc), so I am not sure what the possibility of a non-physical component adds to the model.
