This week being the first
anniversary of the Newtown school massacre, I thought it a good time to try to
write something about that age-old debate: are we humans by nature warlike
killers, or are we peacemakers who are driven to pursue happiness? A book and a video and an article have each
added fuel to one side or the other of this argument: anthropologist Napoleon
Chagnon’s recent memoir, Noble Savages,
about his more than 30 years studying the Yanomamo of the Venezuelan/Brazilian
rainforest; the documentary shown recently on PBS called “Happy”; and a piece
from Think Progress, “Five Reasons Why 2013 Was the Best Year in Human
History.” Though they seem to be at odds, taken together they may add up to a
reasonable view of just what we, as humans, are and have been and may be
evolving to be.
Chagnon has a
fairly simple, though not uncontroversial theory. Based on his years living
with the Yanomamo—an essentially stone-age people living in small villages
where, until recently, they hunted, fished, gathered local crops, and farmed
some of the staples like bananas and manioc that sustain them—Chagnon concluded
something radical: their frequent fights and wars with their neighbors were not
about gaining better territory or increasing their hold on material goods.
Rather, their raids were almost always about capturing women. The headman of a
group would almost always initiate such raids, as he was the one who almost
always came away with an additional wife or wives (the Yanomamo practice polygyny, where the most powerful men
have more than one wife.) This in turn meant, according to Chagnon, that the
Yanomamo, like most other biological organisms, compete for reproductive access
and success: whoever has the most wives has the most offspring, and therefore
the most allies to count on whenever a conflict comes up. Those within a given
village cooperate with others (villagers are mostly related), but inter-village
rivalry is intense and often leads to ‘wars’ where many warriors get killed.
These wars, in turn, most often result from the attempt to avenge a previous raid
where women were abducted. This accords with Chagnon’s research which shows
that most Yanomamo villages have a shortage of women, first because of
preferential treatment of male offspring (who are helpful in wars), and second
because of polygyny: even were the number of males and females in a village roughly
equal, the fact that powerful men take several wives means that there are not
enough females for all the males who want one.
Many
anthropologists dispute Chagnon (and also Jared Diamond whose recent books have
emphasized this same extreme warlike tendency among tribal peoples in New
Guinea, who always consider a stranger a dangerous enemy) about both the
warlike nature of primal humans and the reasons for their wars. This is why
Chagnon subtitles his book: “My life Among Two Dangerous Tribes—the Yanomamo
and the Anthropologists.” According to him, conventional anthropologists insist
on a materialist view of human culture. That is, conflict is believed to arise
over access to good land for growing crops, over power in the most material
sense of ownership of the most valued goods or means of production, but not
over access to females. Chagnon, by contrast, is persuasive in his argument
that the access to fertile females really is the key to conflict. In his view,
humans are like all other organisms, wherein individual males fight with other
males to gain access to females and reproductive success; and where females
tend to select the most powerful males (and their genes) so as to give their
offspring the best chance to survive. Everything then flows from this: the
constant wars, the tendency of males to be killed in such wars (thus producing
even more imbalance between men and women), and the constant rituals and games
training males for combat. And if we look at some of the early documents in
human history, such as the Iliad of
Homer, we can see that though the Mycenean Greeks had a very advanced culture
compared to the Yanomamo, the root cause of their legendary war was the
abduction of a choice female—in this case the abduction of Helen, the beautiful
wife of Menelaus, by Paris, which led directly to the tragedy: the siege of Paris’
city by the allies of Menelaus and the destruction of that home, Troy, along
with all the Trojans save a few who managed to escape. Not coincidentally, those
few, according to legend, founded the next great city-state, Rome, where,
according to another legend, there followed the abduction or rape of the Sabine women
from the indigenous people so that they, the mostly male followers of Rome’s mythic
founder Romulus, could have wives and many offspring. Up to the present day,
most literature relies for its drama on this same male conflict over females—in
a sublimated form, to be sure, but with the same essential roots.
Chagnon’s research
uncovered one more contributing fact to this thesis. The male warriors who have
killed at least one enemy in their battles are known as unokais. Chagnon has a chart in his book showing the relation of unokais to the number of offspring. The
summary is clear: unokais have
almost three times as many offspring
as those men who have not killed anyone. That is, the unokais had, on average, 4.91 children compared to the same-age non-unokais, who average only 1.59 offspring
each. Among the yanomamo, at least, it pays to be a killer.
I should make
clear at this point that I am mainly a pacifist with an abhorrence of war and
fighting, so these conclusions do not please me. I would prefer a view that
accords with Jean Jacques Rousseau’s idea that humans in a state of nature,
without the corruptions attendant to civilization, would have been innocent and
playful and loving and peaceful—noble savages. But I also have a commitment to
the truth, and the truth seems to be that in the earliest human groups, killing
of rivals was routine, and that killing, as with all other animals, most often
occurred in the conflict that erupted over access to females. Those who were
most successful in battle were most often the ones whose genes were passed on
through reproduction. It is not hard to see, even today, the indelible marks of
that pattern in our cultural preoccupations, in our sports, in our wars, in our
very brains.
The video entitled
simply “Happy,” takes another view entirely. Like many others today, it
emphasizes the benefit of cooperation, of helping others, of being involved in
community. We are shown several “happy” communities: the Himalayan kingdom of
Bhutan, where the nation’s output is measured as “gross national happiness;”
Okinawa, which boasts more 100-year-olds per capita than any other place on
earth; several people being trained to meditate focusing on compassion for
others, whose brains are literally said to change for the better as a result;
the San Bushmen of Namibia, who testify to their complete interdependence, and
therefore their happy outlook; and a co-housing community in Denmark (said to
be the happiest industrial nation on earth) where about twenty families live
together while working at normal jobs but are happy due to the sharing of
cooking, childcaring and other chores. We are also shown the rat-race in Japan,
and one family in particular whose male head worked such long, intense hours
for Toyota that he simply dropped dead from overwork. Modern industrial Japan
is said to be the most unhappy nation on earth.
The documentary
also presents us with scientific validation of its message. Neuroscientist
Richard Davidson shows us how Buddhist monk Ricard Matthieu is put into an MRI
contraption, and measured while he does compassion meditation. His left
prefrontal cortex lights up—indicating that not only is this part of his brain
activated to make him more happy, but also that focusing on compassion changes
the brains of those who engage in it. That is to say, training the brain to
focus on compassion for others, and in fact, actually helping others, re-wires
the brain for more happiness. We are told in the very beginning, in fact, that
it is not material wealth that leads to happiness since, after a certain level
of comfort via possessions, acquiring more wealth simply has no effect. Rather,
what leads to ‘positive’ brain states and the release of ‘happiness’ brain
neurotransmitters like dopamine, are positive acts and thoughts: compassion,
cooperation, and relationships with others. P. Read Montague, PhD says this
specifically: cooperation, working with others, actually produces dopamine in
the brain, in effect being just as good in this regard as taking drugs. Added
to the testimony of old women in Okinawa smiling and dancing, and one single mother
in the Denmark co-housing community brightly telling us how well cared for she
and her children have become since living there—with the children even taking
part, once a month, in cooking for the whole community—this becomes a powerful
argument for changing the way most modern humans behave (looking out for number
one) and how modern industrial communities (commit any act to increase profit)
are structured.
It also challenges
the post-Darwinian view that humans are naturally prone to conflict and war due
to the evolutionary demand to augment, in whatever way possible, the number of
offspring one has. Human nature, in this view, is simply a variant of most
animal nature: a no-hold-barred competition to survive and out-reproduce all
rivals. Rather, according to “Happy,” human nature must be seen to include the
positive effects of selflessness and cooperation and a supportive community. To
be sure, these emotions have always been available, even to warrior societies.
The difference here is the idea that compassion for all—not just one’s
immediate family or neighbors or nation—leads to even more positive effects. We
see Andy Wimmer, for example, who trained and worked as a banker, until one day
he decided there must be more. He signed up to work in Mother Theresa’s home in
India caring for the sick and dying. According to his testimony, and despite
having to wash and feed dying, suffering humans, he has never felt more fulfilled,
happier. The same testimony is given by a woman hospice worker who deals with
terminally ill people all day every day. She is bright, cheerful, and
apparently unaffected by the dire circumstances that surround her. And it is
obvious that those whom she treats and encourages adore her.
Finally, the
article by Zack Beauchamp of Think Progress, reprinted on Nation of Change (
http://www.nationofchange.org/5-reasons-why-2013-was-best-year-human-history-1386859589)
offers 5 reasons why 2013 was ‘the best year in human history.’ The reasons
are: 1)
Fewer People are Dying Young,
which shows that as recently as 1950, global life expectancy was 47 years,
while today it is 70 years. In other words, averaged globally, most people live
twice as long today as they did in 1950. This is due both to medical technology
and a growing interest in the welfare of foreigners—as indicated by the
assistance given to poor countries in fighting diseases like smallpox,
tuberculosis, and HIV. 2)
Fewer people
suffer from extreme poverty, with its corollary, a happier world. Just since
1981, the percent of the population that lives on less than $1.25 a day has
dropped, globally, from 40% in 1981 to 14% in 2010. Even in low income
countries, the percentage has dropped from 63% in 1981 to 44% in 2010. 3)
War is becoming rarer and less deadly.
According to Steven Pinker’s book
The
Better Angels of Our Nature, both war and related forms of violence,
including the death penalty, are on a clear decline, especially in the last
fifty years. From nearly 300 war-related deaths per 100,000 world population
during World War II, the rate has declined to less than 1 death per 100,000 in
the 21
st Century. Even the death rate in civil wars has declined.
Among the factors contributing to the decline are the spread of democracies
worldwide, and the invention of U.N. and other peacekeeping operations. 4.
Murder rates and other violent crimes are
in free-fall. Even in the U.S., violent crime has declined from its peak of
750 crimes per 100,000 Americans in the 1990s to less than 450 in 2009. The same
decline is seen in other countries. Among the major reasons—including better
lives from improved economies—is one surprising one: the decline in leaded
gasoline. With lead banned in 175 countries, the decline in blood levels of lead has
reached 90%, and this decline tracks the decline in violent crimes. The reason:
lead exposure damages the brain, specifically the parts that inhibit people’s
aggressive impulses. With the decline in lead comes more control and less
violent crime. And finally, 5)
There’s
less racism, sexism, and other forms of discrimination in the world. This
is not to say that racism is dead. Far from it. But there is also no denying
that greater tolerance is demonstrable everywhere. Look only at the disabling
of white minority rule in South Africa, or the fact that much of the United
States, where discrimination was once openly defended, now operates under a
national consensus about the ideal of racial equality and integration—not
always honored in every situation or locality, but increasingly prevalent,
especially among younger populations who will soon be the majority. And when it
comes to marriage equality for all, regardless of gender preference, the trend
is clearly towards greater tolerance: in 2003, there were no states with
marriage equality laws; today there are so many that 38% of Americans live in
states with such laws.
What, then, are we
to conclude about the nature of human nature? Are we humans, by nature,
xenophobic, paranoid killers of anyone who is a stranger or a rival? Or are we
cooperative creatures disposed to tolerate each other regardless of outward
appearances or origin, cooperate with each other beyond familial or national
borders, compassionate creatures who, in helping those who need it, become more
and more happy with ourselves?
Perhaps the best
we can say is that the truth seems to be both. There is no doubting that
evolution has shaped us to be violent, aggressive creatures who fight with
little provocation and who routinely kill those who threaten either our
well-being or our ability to reproduce. But there can also be little doubt that
our brains—particularly the more recently developed parts of our brains: the
neocortex and especially the left prefrontal cortex involved in compassion—may
well be evolving (spurred by the example of culture heroes like Nelson Mandela and
Martin Luther King and the Dalai Lama) towards less aggressive, more
compassionate patterns. Otherwise, why would acting compassionately, placing
the welfare of others over our own, and living in cooperative and communal ways
deliver the good feeling we now know to be the product of dopamine release?
This is not to say that dopamine release was “designed” to make humans
cooperate (it was designed to provide a powerful reward for whatever enhanced
our survival). Rather, it is to say that human development seems to be
employing the available neurotransmitters to a greater extent in ways that
foster the expansion of cooperative, communal, helping behavior. Whether this
trend will continue is anyone’s guess. Life has a way of confounding our
fondest hopes and expectations. But if what some of the evidence shows is true,
then human development, as Abraham Maslow long ago suggested, is moving towards
an optimum functioning marked by greater tolerance, empathy, and helpfulness
towards not only our fellow nationals or even fellow humans but the entire
planetary population. The only question remaining is, will it come soon enough to
head off the residual disasters—nuclear weapons, global warming, the die-off of
species—that our older operating kit has brought to critical mass.
