And
the little son of a birch looked up and said, Daddy, tell me an understory.
Why
do we love stories? I here suggest that our brains evolved that way, at least since our evolutionary lineage, Homo sapiens, became distinct from the
other ape lineages.
The
natural world can be a brutal, frightening place. It is full of predators,
poisonous critters, diseases, droughts, storms. And, most of all, other human
tribes who want to claim our hunting grounds as their own. Humans have fought
over hunting grounds since prehistory, and as late as 1755, when the Cherokees
fought the Creeks over the hunting ground at Taliwa, now part of Georgia. My
sixth great grandmother Nanyehi was the Cherokee war hero in that battle.
To
fight a battle, a tribe needs a military leader. Often, tribes have distinct
war and peace leaders; traditional Cherokees had a war chief and a peace chief
simultaneously. If the military leader brings about a victory, he brings the
news back to the tribe and relates it in a narrative format, in which he is the
hero, supported by his loyal followers, and in which victory was not due to
luck but to the prowess and skill of the warriors, especially him, and to the
blessings of their gods. And he (or she) might bring back physical plunder to
share altruistically. This is the most visceral form of narrative.
In
the ensuing time of peace, guess who gets the most resources and the most
reproductive opportunities? Why, the military leader (war chief) and his top
aides. That is, the leader who not only won the battle but could tell a story.
All in the tribe who bought into the story stood a better chance of getting
resources and reproductive opportunities. The genes for brains that not only
were capable of, but craved, the narrative form spread in the population.
Making sense of the world, especially in the form of religious narrative, might
have been one of the major selective forces that resulted in the particular
form of human intelligence that we have.
And
the myth must be about an individual, not a collective. Even when the Soviets
tried to champion stories about heroic collectives of peasants against the
bourgeoisie, they had to create individual heroes; and Stalin was only too
happy to assume the role of hero himself.
As
I will explain in my forthcoming book tentatively titled Scientifically Thinking, due out in 2018 from Prometheus Books, the
human brain did not evolve to reason, but to rationalize; not to see truth but
to create it, so as to manipulate other people. Natural selection favored
brains that were delusional. Not too delusional, but sometimes pretty close to
it, as when religion causes some people to follow a leader to senseless deaths.
We cannot jeer at the Jonestown cult, because their brains were not too
different from ours. We evolved from the tribes that followed their leaders to
the deaths of many in the tribe, but from which enough survived to enjoy the
spoils of war and to reap the fitness benefits from it. This may have worked
well enough in the past, but today our population and technology has grown so
much that this kind of thinking threatens our survival. Having an ape brain
couldn’t have come at a worse time.
The
scientific method can unleash our minds. But you can see the kind of uphill
battle we face.
