Just as Hypnotism, through the very dramatic abnormality of it, in altering the sensitiveness of those physical tracts from which attention is withdrawn or in producing physical effects through suggestive focusing, has helped us to understand the part which attention plays in the flux of physical states, so our later studies of the subconscious help us here. We do know that a great deal may really take place in personality of which consciousness takes no account. Consciousness in its most active phases is alert, purposeful and preoccupied with the immediate concern of the moment. Consciousness heeds commands and takes account of such conditions as strongly assert themselves, but does not in its full drive take much account of suggestion unless the suggestion possesses unusual force. Suggestions usually need leisurely turning over in the mind and the mind commonly refers them--often without knowing it--to those regions of mental action which lie beneath the threshold of strongly focused consciousness. But suggestion does not thereby cease to work. It starts processes all its own which go on till they are worked through. After a longer or shorter period of incubation the outcome of suggestion is lifted into the light of consciousness, often to produce results all the more striking because we cannot explain them to ourselves or any one else. All this does not withdraw such phenomena from the realm of law; it only clothes them with the mystery of the unknown and extends the fields in which they may operate. Proper suggestion let fall into these unknown depths or improper suggestion as well, becomes an incalculable force in shaping the ends of life. We have here, then, well attested truths or laws--it is difficult to know what to call them--which help us to understand the bases of faith healing or mental healing by suggestion. Now directly we turn to such records as remain to us we find that such forces as these have been in action from the very beginning. All disease was in early times referred generally to spirit possession. If only the evil spirit could be exorcised the patient would get well and the priest was, of course, the proper person to undertake this. Religion and medicine were, therefore, most intimately united to begin with and healing most intimately associated with magic. The first priests were doctors and the first doctors were priests and what they did as priests and what they did as doctors were alike unreasonable and capricious. The priest and his church have very unwillingly surrendered the very great hold over the faithful which this early association of medicine and religion made possible. Any order or institution which can approach or control humanity through the longing of the sick for health, has an immense and unfailing empire. _Demon Possession the Earliest Explanation of Disease_
