Consciousness is not a simple matter and it should not be spoken of as if it were. Nor have I mentioned the different modes of conscious narratization such as verbal (having imaginary conversations — certainly the most common mode in myself), perceptual (imagining scenes), behavioral (imagining ourselves doing something), physiological (monitoring our fatigue or discomfort or appetite), or musical (imagining music), all of which seem quite distinct, with properties of their own.


Another advantage of schizophrenia, perhaps evolutionary, is tirelessness. While a few schizophrenics complain of generalized fatigue, particularly in the early stages of the illness, most patients do not. In fact, they show less fatigue than normal persons and are capable of tremendous feats of endurance. They are not fatigued by examinations lasting many hours. They may move about day and night, or work endlessly without any sign of being tired. Catatonics may hold an awkward position for days that the reader could not hold for more than a few minutes. This suggests that much fatigue is a product of the subjective conscious mind, and that bicameral man, building the pyramids of Egypt, the ziggurats of Sumer, or the gigantic temples at Teotihuacan with only hand labor, could do so far more easily than could conscious self-reflective men.


If we are correct in assuming that schizophrenic hallucinations 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 over 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 breakdown products of stress-produced adrenalin which the individual is, for genetical reasons, unable to pass through the kidneys as fast as a normal person. 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 because 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. 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 94 The Mind of Man cross an electric grid each time they wish to get food and water, such rats develop ulcers.11 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.12 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 they are often called, do not occur.13
