Abstract

The essence of consciousness, the ability to know self, is not something that can be detected with the aid of physical devices. Therefore, the study of consciousness cannot be limited to the methods of sciences. A human being is the “detector” of his or her own self and so a human being is in a sort of space with both physical and nonphysical dimensions. The latter is what C. S. Lewis calls “Supernature.” Conceptual thought, free will, moral autonomy, the notion of God, etc. are all unique to humans and cannot be reduced to the purely physical. Of course, different levels of conscious experience are related to brain-states but self cannot be reduced to such physical states. It is analogous to electrical charge that must always be accompanied by mass but cannot be reduced to it.
