These are excerpts and elaborations from my book "The Nature of Consciousness"
The Origins of Civilization Sometime in the neolithic
past, humans discovered agriculture. At about the same time they started
creating cities. Beliefs coalesced around religions and political structures
arose. One way to look at this story is that the transition from
hunter-gatherer to farmer caused a new way of thinking that yielded religion
and cities. Another way to look at this
story is that a new way of thinking (due to a physical change in the structure
of the human brain) led to religion and philosophy, and this new way of
thinking manifested itself in agriculture and cities. A very small change in the
genome can cause a very big difference in the brain (after all humans share
98.5% of their genes with chimps, and the genome of Homo Sapiens is virtually
identical to the genome of the Neanderthals) and a very small change in the
brain can cause a very big difference in behavior. The traditional narrative is
that humans discovered agriculture and created cities, and then
religion/politics evolved because agriculture/cities fostered a new way of thinking, and this new way of
thinking was more rational than the previous one; but one can also view it the
other way around. For whatever reason the
bodies of Homo Sapiens change over the centuries. The most visible feature is
the height: we are way taller than neolithic people. There might also take
place more subtle changes in the brain. When the brain changes in some individuals, the other
individuals call it "madness". However, when the change is caused by
diet, pathogens or some unknown biological law, it can spread just like any
epidemic. As more and more individuals acquire the new brain, eventually they
come to rule: their brain is now the “modern” brain, and their thinking is
superior to the old thinking of the “traditional” brain. The new brain causes a new
way of thinking, initially viewed as madness but later simply accepted as
"modern". The modern way of thinking causes new behavior. Eventually
only the children born with this new brain are accepted and reproduce. The
others die away. According to this alternative
narrative, at some point the “modern” brain of the neolithic individual started
forming symbolic systems that we now call "religion" and
"politics". That new way of thinking caused a change in behavior,
from hunting/gathering to agriculture and cities, not because it is more
rational and efficient, but simply because their brains started thinking that
way. Needless to say, a brain tries to prove to itself that it is the best
brain ever. (Whatever you think the brain
is, it's your brain talking about itself). The new brains convinced themselves
that the transition to agriculture was the right thing to do and that such a
transition constitutes "progress", that it was rational discovery
when in fact it was irrational self-delusion. Because the archeological
record does not show which one happened first (agriculture/cities or
religion/philosophy), historians assumed that agriculture happened first; but it may well be the other
way around: first our brains started
(accidentally) believing in deities of fertility, rain dances and river spirits; and then we started farming and
creating cities. That is idea that the French archaeologist Jacques Cauvin proposed. In that case we may have
been doing this for thousands of years.
We think it has been constant rational progress, i.e. better adaptation
to the environment, but in fact changes in behavior have been driven by random
changes in the brain; which means that sometimes we adapt better and sometimes
we don't. But every time our brains convince themselves that we adapted better. Back to the beginning of the chapter "A History of Consciousness" | Back to the index of all chapters |
