Contrary to horror fiction stories, negatory possession is chiefly a linguistic phenomenon, not one of actual conduct. In all the cases I have studied, it is rare to find one of criminal behavior against other persons. The stricken individual does not run off and behave like a demon j he just talks like one. Such episodes are usually accompanied by twistings and writh-ings as in induced possession. The voice is distorted, often guttural, full of cries, groans, and vulgarity, and usually railing against the institutionalized gods of the period. Almost always, there is a loss of consciousness as the person seems the opposite of his or her usual self. 'He' may name himself a god, demon, spirit, ghost, or animal (in the Orient it is often 'the fox'), may demand a shrine or to be worshiped, throwing the patient into convulsions if these are withheld. 'He' commonly describes his natural self in the third person as a despised stranger, even as Yahweh sometimes despised his prophets or the Muses sneered at their poets.12 And 'he' often seems far more intelligent and alert than the patient in his normal state, even as Yahweh and the Muses were more intelligent and alert than prophet or poet. As in schizophrenia, the patient may act out the suggestions of others, and, even more curiously, may be interested in contracts or treaties with observers, such as a promise that 'he' will leave the patient if such and such is done, bargains which are carried out as faithfully by the 'demon' as the sometimes similar cove-nants of Yahweh in the Old Testament. Somehow related to this suggestibility and contract interest is the fact that the cure for spontaneous stress-produced possession, exorcism, has never varied from New Testament days to the present. It is simply by the command of an authoritative person often following an induction ritual, speaking in the name of a more powerful god.

If we are correct in assuming that schizophrenic hallunications are similar to the guidances of gods in antiquity, then there should be some common physiological instigation in both instances. This, I suggest, is simply stress. In normal people, as we have mentioned, the stress threshold for release of hallucinations is extremely high; most of us need to be oever our heads in trouble before we would hear voices. But in psychosis-prone persons, the threshold is somewhat lower; as in the girl I described, only anxious waiting in a parked car was necessary. This is caused, I think, by the buildup in the blood of a breakdown products of stress-produced adrenalin which the individual is, for gentical reasons, unable to pass through the kidneys as fast as a normal person.\n\n During the eras of the bicameral mind, we may suppose that the stress threshold for hallucinations was much, much lower than in either normal people or schizophrenics today. The only stress necessary was that which occurs when a change in behavior is necessary becuase of some novelty in a situation. Anything that could not be dealt with on the basis of habit, any conflict between work and fatigue, between attack and flight, any choice between whom to obey or what to do, anything that required any decision at all was sufficient to cause an auditory hallucination.\n\n It has now been clearly established that decision-making (and I would like to remove every trace of conscious connotation from the word 'decision') is precisely what stress is. If rats have to cross an electric grid each time they wish to get food and water, such rats develop ulcers*. Just shocking the rats does not do this to them. There has to be the pause of conflict or the decision-making stress of whether to cross a grid or not to produce this effect. If two monkeys are placed in harnesses, in such a way that one of the monkeys can press a bar at least once every twenty seconds to avoid a periodic shock to both monkeys' feet, within three or four weeks the decision-making monkey will have ulcers, while the other, equally shocked monkey will not*. It is the pause of unknowingness that is important. For if the experiment is so arranged that an animal can make an effective response and receive immediate feedback of his success, executive ulcers, as there are often called, do not occur*.'\n\n *W.L.
