These are excerpts and elaborations from my book "The Nature of Consciousness"
The Bicameral Mind The studies conducted by the
US psychologist Julian Jaynes (and, before him, by the German
classicist Bruno Snell) gave credibility to the
idea that consciousness may be a recent acquisition of our mental life, or at
least that consciousness was not always what it is today, that it was and still
is evolving. By reviewing historical,
archeological and biological documents from ancient civilizations, he concluded
that until about 3000 years ago human beings were still devoid of
consciousness. They still relied, like all other primates, on learned reactions.
The people of even the most developed civilizations before 1000 B.C. (ancient
Assyria, Babylonia, Mesopotamia, Egypt) were not “truly” conscious. Ancient
books such as the Iliad and the Bible were composed by non-conscious minds that
explains why they could not distinguish between real and imagined events. The
characters of those books act unconsciously in making their decisions and
always rely on "voices". They tend to speak in hexameter rhythms,
which are characteristic of the automatic processing of the right-hemisphere
brain. Schizophrenics often tend to speak in the same rhythm. These stories are
all action and no introspection. Ancient people, because
non-conscious, did not feel responsible
for their actions. They had no concept of good and evil. They had no conscious
memories. They had no interest in history (past). They had no interest in
progress (future). They had no sense of themselves. Human beings did already
employ language to communicate with other human beings, and to cooperate and to
build societies and civilizations, but, in each individual's head, that
language did not serve as conscious thought: it served as communication between
the two hemispheres of the brain. Human beings were guided not by conscious
reasoning, but by "hallucinations". Hallucinations would form in the
right hemisphere of the brain and would be communicated to the left hemisphere
of the brain, which would then receive them as commands. This is what Jaynes
refers to as the “bicameral mind”. Human beings were led by these voices in
making their important decisions. "God" is one manifestation of the
bicameral mind. God is the main voice that would drive individual and social
behavior. With the emergence of oral languages, the hallucinating voices for
performing fundamental actions became standardized and consequently societies
became increasingly organized. A conscious mind appears in
the Odyssey and the most recent part of the Bible, about 3000 years ago. Those
writings gradually shifted from non-conscious actions to conscious decisions.
In the Odyssey characters are aware of the moral and physical consequences of
their actions. In the West, moral issues started spreading in written languages
around the sixth century B.C. Chinese literature moved from the bicameral mind to
the conscious mind about 500 B.C. with the writings of Confucius. Indian
literature shifted to consciousness around 400 B.C. with the Upanisad. At that time, the bicameral
mind began breaking down under the pressure caused by the complexity of the
environment (mainly, society). The
hallucinated voices became confused, contradictory, and ultimately
counterproductive. They no longer
provided automatic guidance for survival. At the same time, the development of
writing, and the permanent recording of procedures, in 2,000 B.C.,
progressively reduced the need for guidance from the hallucinated voices and
replaced them with a much more effective means of organization. Consciousness
was therefore invented by human beings through a process that entailed the loss
of belief in gods and natural selection itself, which started rewarding
conscious individuals over non-conscious ones. Jaynes thinks that, today,
governments and religions, and psychological phenomena such as hypnosis and
schizophrenia, and artistic practices such as poetry and music, are vestiges of
that earlier stage of human consciousness, when action was guided by the
bicameral mind, because these are all manifestations of an instinctive tendency
towards seeking directions, or, in general, automatic guidance, from others. Today, these two minds still
coexist: the non-conscious bicameral mind that seeks guidance from
"authorities" for important decisions in complex situations (such as
those related to society); and the conscious mind that creates its own
decisions in more local and manageable conditions. Jaynes' concept of
consciousness was revolutionary. First of all, intelligence (or, more
appropriately, cognitive faculties) and consciousness are not the same thing
and they are only vaguely related. Consciousness is not necessary for concepts,
learning, reason or even some elementary
forms of thinking. Non-conscious beings can develop sophisticated
civilizations. Secondly, awareness of an
action tends to follow, not precede, the action. Awareness of an action bears
little or no influence on the outcome. Before one utters a sentence, one is not
conscious of being about to utter those specific words. Thirdly, consciousness is an
operation rather than a thing. Consciousness requires metaphors to express one
thing in terms of another. Consciousness is being able to construct one's
narrative in terms of metaphors. Consciousness requires analogy to transform
things of the real world into meanings in a metaphorical space. The mental
space is created through metaphors and analogies. Metaphors and analogies map
the functions of the right hemisphere into the left hemisphere and make the
bicameral mind obsolete. Metaphors of "me" and analogies of
"i" enabled a greater understanding of the world and of other individuals.
In turn, consciousness expanded by creating more and more metaphors and
analogies. Ultimately, consciousness is a metaphor-generated model of the
world. Jaynes thinks that
consciousness could not have been invented if language had not evolved to the
point of facilitating metaphorical thinking. And, while oral languages
developed around 70,000 B.C. and written languages began about 3000 B.C.,
metaphorical structures did not appear until about 1,000 B.C. Early writings in
hieroglyphic and cuneiform forms reflect a non-metaphoric and non-conscious
attitude. Back to the beginning of the chapter "A History of Consciousness" | Back to the index of all chapters |
