 By contrast, our notion of demons did not come to find a new home in contemporary theories of mental disorder. There is nothing in the theories of schizophrenia, Tourette’s Syndrome, neuro-pathology or any of the other modern explanations for bizarre behavior, that we can sensibly identify with malevolent spirits with supernatural powers. The notion of a demon is just too far removed from anything we now posit to explain behavior that was once explained by demonology. Consequently, the transition from demonology to modern accounts of this behavior was ontologically radical. We dropped demons from our current ontology, and came to realize that the notion is empty—it refers to nothing real.
