Gods, Voices and the Bicameral Mind: The theories of Julian Jaynes
Julian Jaynes, a professor of psychology at Princeton, is responsible for the most intriguing and extensive thesis yet to emerge from brain research. Did our ancestors have god-directed minds? Is consciousness little more than 3,000 years old? He starts by asking what consciousness is - that irradicable difference between what others see and our own sense of self. Consciousness is not the same as being awake. To be knocked 'unconscious' is to lose many automatic functions. It is not continuity since even 'stream of consciousness' is full of gaps. The Cartesian notion of 'the helpless spectator' asks us to believe that the intensification of consciousness during decisions has nothing at all to do with outcomes. We know that we can learn, judge, think abstractly and even generalize without consciousness (see Map 9). Many skills like oratory, music and skiing fail us when consciousness interferes. Einstein had so many creative ideas while shaving that he would cut himself with surprise.
Jaynes' solution is that consciousness is a metaphor, a relationship between two or more unlike experiences joined by likenesses. The countryside 'blanketed by snow' is more than a superficial connection. It teems with associations, contours, warmth, protection, slumber, and an awakening in spring. Consciousness is a lexical field, whose terms are metaphors or analogues of behaviour in the physical world. We project syntheses of associations into an imagined screen within our heads. Consciousness has thus the relationship of a map to a territory, as when in the 'pith' and 'kernel' of Jaynes' thesis he mounts metaphors on metaphors in levels of abstraction (see Maps 39-40). The origins of even our most basic verbs are metaphorical. 'To be' is from Sanskrit bhu 'to grow'. 'Am' and 'is' derive from amsi 'to breathe'. Thus the metaphor of our being is literally stretched like a screen between brain hemispheres and between referents like growing, breathing and standing out (ex-istere). Conscious being is the relationship between these, a 'between'.
Jaynes sees consciousness as right-left brain synthesis with five characteristics: 1. Spatialization, when we stretch out dimensions of time and space. 2. Excerption, by which maps record only selected parts of the territory. 3. The analogue 'I' and 'me', a projected personification of ourselves moving in space and time which anticipates doing and being done by. 4. Narratization, wherein events are selected for their congruence and sequential unfolding. 5. Conciliation, wherein experiences are consciously assimilated to each other.
With consciousness so defined we must recognize that in a book like the Iliad (shorn of its later accretions), human beings are not conscious at all! Words are not used metaphorically, but have only their original concrete referents from which consciousness later developed. Hence psyche in the Iliad means 'breath', not soul or conscious mind as it meant by the sixth century BC. Thumus means motion or agitation of limbs not emotional sensibility. Nous means simple perception not the imaginal mind, and so on. Jaynes believes that the world of the Iliad, indeed the whole known world of theocratic god-kings, prior to about 1500 BC was possessed of a bicameral mind, split in two, with a right hemisphere, executive part called a god, and a left hemisphere, follower part, called a man. Gods ordered men to act, directly or through priests and men obeyed. There was no argument, love or personal relationship with divine executors.
For the most part such minds would operate, learn, think, react and retain equilibrium as ours do, unconsciously. But when something unexpected happened and hence stressful, instead of a period of intense consciousness, with inner deliberation and argument, bicameral man would receive a god-like command from his right hemisphere instructing him to act, as Zeus ordered Agamemnon to attack before the walls of Troy. This is essentially similar to the reported auditory hallucinations in schizophrenia, which are frequently accurate comments on events, and which Jaynes regards as partial relapses to an earlier state of ancestral bicamerality. Just as contemporary psychotics have a low stress tolerance, combined with an existing schizoid form of personality organization, so that breaks occur readily, so bicameral civilizations heard stress-precipitated commands at almost every crisis point. The remarkable unanimity of such mass action is a consequence of pre-structured collective beliefs, just as the patients of phrenologists oblige with behaviour appropriate to the bump being magnetized and research has found that hypnotized subjects confine themselves to actions which they considered 'possible' and 'permissible before hypnosis began.
Were whole peoples once organized by a mixture of hallucinated voices and hypnotic suggestions? Incredible? Jaynes has amassed considerable circumstantial evidence to which this precis cannot do justice. Recall from Map 23 that speech areas are almost entirely confined to the left hemisphere (that is for the 95% of the population which is right handed). This high degree of hemisphere specialization is peculiarly human, and is generally attributed to language acquisition. There are three major language areas (see diagram), the supplementary motor area, Broca's areas, low down on the left frontal lobe, and Wernicke's area, mostly in the posterior part of the left temporal lobe. The latter seems the most crucial, since extensive damage involves permanent loss of language function, while equivalent damage to the right temporal lobe produces deficit, despite the near-identity of neural structures. However, persons with left temporal lobe damage at birth utilize their right hemispheres to acquire language, so what is this vast underutilized area for?
Jaynes believes that during a crucial period in our evolution, at the very time that language was being acquired by the left hemisphere, the right temporal lobe was pre-empted for the issuance of god-like commandments, across the thin anterior commissure that joins the two temporal lobes like a private corpus callosum. Auditory commands would have been the most economical code for getting elaborate information processing through so small a channel.
When this hallucinatory area was stimulated by an electric current in recent experiments by Wilder Penfield, subjects would hear voices (and sometimes have visions) addressing them. One typical subject exclaimed, 'That man's voice again! My father's ... and it frightens me!' Others heard voices to the accompaniment of music, chanting or singing, which would criticize, advise, command, but they were consistently other than the hearer, often a dead relative or friend. We also know that while the right hemisphere cannot speak, or barely so, it can comprehend and interpret quite complicated instructions. Patients with strokes in their left hemisphere can obey their doctors or researchers in detail.
Recall also that when the corpus callosum between the hemispheres is severed or communication anaesthetized, one hemisphere can try and 'help' the other in the manner of two, independent persons. The left hemisphere feeling a frown on the face, produced by the right hemisphere, whose left hand knows the answer, will be prompted to change its verbal answer. It is like Athena taking Achilles in hand. For in many respects the right hemisphere acts in god-like ways. It is timeless, immediate, visionary, coherent, with recognizable forms and faces. It responds to over-arching purposes and grand designs and has an affinity for music, rhythm, cadence and patterns in general. It binds people together (religion is from religare 'to bind') and its intuitive style is given to inspiration and seeming miracle.
How could bicamerality have evolved? There was no one to cut the corpus callosum. Jaynes argues from studies that reveal the great plasticity of the brain to changes in environment. Persons with their brains damaged have developed additional areas to overcome injuries. The principle of natural selection could well have given an advantage over several millenia to persons bicamerally organized. They may have evolved from small groups of hunter-gatherers into whole communities remotely controlled by the internalized voices of god-kings, a form of social control far more sophisticated than the signs and calls of earlier primates, and one that allowed for the development of language.
Jaynes dates bicameral man from the Natufian settlement at Eynan just north of the Sea of Galilee, discovered in 1959. Those parts of it which date from 9000 BC show town settlements theocratically organized around the burial mounds of god-kings. Thenceforward theocratic organization spread rapidly with dead kings as living gods and their tombs as temples. We find them propped up on thrones of stone, surrounded by food and gifts. Later, some bicameral theocracies became literate, the Babylon of Mesopotamia, the Kings of Ur and Isin, the Memphite theology, and the Dead King's Voice of Osiris. These were not 'authoritarian' regimes, for there was no subjectivity or private ambition to crush, only an innocent obedience to voices reverberating in the brain.
The end of bicameral civilizations may have come from the strains produced by their initial success. Controlling more than a thousand people must have posed difficulties, but nothing compared with the conflicts resulting from collisions between god-programmed peoples each marching to a different drummer. The biblical story of the Tower of Babel may well refer to this. The spread of writing must also have weakened auditory commands. But the most proximate cause was surely the cataclysmic events in the second millenia BC, when volcanic eruptions on the island of Thera, estimated to have been 350 times greater than an H-bomb, turned half the world's known population into refugees and drowned the lost continent of Atlantis beneath a tidal wave 700 feet high. The once stable hierarchies crumbled in mass migrations, wiping out the great empires of the Hittites and Mycenae, as primal hordes turned on god-kings ... Assyria having fallen into two centuries of anarchy emerged as a monster of sadistic ferocity, terror replacing the sudden loss of authority.
Yet there was no turning back to lost Edens. The languages, cities and foreigners were there and only consciousness could survive in the confusion. The Odyssey, which probably followed the Iliad by at least a century, is a myth marking the transformation. The heroes who battle before Troy 'were the will-less gigolos of divinities' whose Olympian rivalry was in bloody impasse. It took 'wily Odysseus' and his Trojan Horse to break free, conquer Troy, and defying gods wander homelessly abroad using the serpentine wits of an exiled Adam. In the Odyssey we suddenly encounter conscious actors, moral judgements and psyche, nous and thumus used as metaphors for consciousness. We find a similar transition between Amos and Ecclesiastes, from 'Thus Spake the Lord . . .' to 'For all things there is a season . . .'The Lord who walks in the Garden and closes the ark, yields to a Yaweh who appears only to Moses in disguise and condemns bicameral idolators.
Jaynes' thesis thus adds to Maps 1 to 5. The Greek epic poets in their tales of mythic heroes were surely celebrating a novel orchestration of hemispheric functions. Tragic drama stressed the price of consciousness, that the hubris of the analogue 'I' on the screen of consciousness could find itself in agonizing contradiction with real events. The psychic heroism of Orestes, Oedipus, Antigone, Socrates, and eventually Christ, was that all remained defiantly conscious in crucifying circumstances which threatened relapse into bicamerality and oblivion of mind.
[Sidebar]
Achilles directed by the goddess Athena, before the walls of Troy, to attack Hector. Throughout the 'Iliad' and in the surviving
fragments of writing before the first millennia BC, there is little evidence that people were conscious. Jaynes argues that human brains from about 9000 to 1000 BC were bicameral, ie that the known halucinatory area in the right temporal lobe processed information intuitively and issued auditory, god-like commands through the anterior commissure to Wernicke's area in the left hemisphere, where the message was relayed or enacted.
In short, the brain was split in a manner similar to schizophrenic functioning, save that sociologically schizophrenics today are withdrawn, stigmatized and relapsed, while in bicameral ages collective cognitive imperatives sanctioned divine commands. Even contemporary schizophrenics have capacities reminiscent of archaic man. A majority of those not on Thorazine report matter-of-fact auditory hallucinations. Schizophrenics surpass normals on sensory perception, allowing themselves to be flooded. Many show the kind of endurance needed to build pyramids, with greater attentiveness in their right hemispheres than normals. Their somewhat thicker corpus callosi may produce greater reciprocal inhibition by one hemisphere of the other, in any event they switch between hemispheres less frequently, and when their left hemispheres become confused or deprived of stimulation, they switch more readily to the right. Theatrical hypnotism, with audiences reinforcing suggestions, is another modern echo of bicameral antiquity.
