Einstein and relativity.
Edison and the light bulb. Newton and that ripe red apple—falling,
it seems, from the tree of knowledge itself. If anyone can change
the way we live, it’s scientists. One such scientist is Edward O.
Wilson, the man whose name is wedded forever to the word sociobiology,
the study of nature’s role in determining human behavior. Wilson
launched a revolution with his monumental 1975 book, Sociobiology: The
New Synthesis. There were 26 chapters covering the biology and behavior
of animals and insects—Wilson is the world’s leading authority on the 9,500
species of ants—but it was the 27th chapter, arguing that genes play a
central role in human behavior, that ignited a public fire and remapped
our world. Like Galileo, who was put under house arrest for saying the
earth moves around the sun, Wilson was ostracized before being canonized.
Colleagues at Harvard University, where Wilson was a professor of biology,
excoriated him as a racist and 15 top scientists damned him in a letter
printed in The New York Review of Books for subscribing to the same genetic
determinism that led to “the establishment of gas chambers in Nazi Germany.”
The two decades since have seen a remarkable turnaround. Wilson has
won two Pulitzers, for On Human Nature and The Ants. He’s been named to
one of the most prestigious professorships at Harvard and elected to the
National Academy of Sciences. Today he is lauded as the world’s most
eloquent biologist and the grandfather of evolutionary psychology, a field
that explores the links between genetic and cultural evolution helps explain
what makes us what we are.
In his newest book, Consilience
(Knopf), Wilson looks up from the ants once again and argues for the unity
of all knowledge. He suggests that a small number of natural laws
underly far flung disciplines—from the arts and religion to biology, anthropology
and psychology—and that it’s time for cross-fertilization. PT’s Jill
Neimark caught up with the 69-year-old scientist recently at the Ritz-Carlton
hotel in New York City for a lively discussion of life, death, the universe,
ants, faith, free will, and whether there is even such a thing as “self”.
PT: Back in 1978, you gave a talk at the Association for the Advancement of Science and were picketed with placards bearing swastikas. A young woman even poured a pitcher of cold water over your head. Twenty years later you write a cover story for The Atlantic called “The Biology of Morality”, and nobody blinks. What’s changed?
EO: The entire political climate of the world has changed. Twenty years ago leftist activists in particular felt science was being used to justify the policies of colonialist governments. There was a moral outrage that has now passed almost completely. The fall of the Berlin wall had something to do with that. And there’s also the mounting evidence from genetics and neurobiology.
PT: Your theory has actually become mainstream.
EO: It’s very respectable now. I was reading a complaint not long ago by an anthropologist who said, “If you want to get a grant, you’d better put some biology in your anthropology.” Twenty years ago if you wanted NOT to get a grant, you put it in.
PT: You’ve said that ants have given you everything, and it’s to them you always return. What have they taught you?
EO: One thing is that natural selection is brutal. It is brutal to see strong, beautiful ant queens and males go forth and realize that they’re all going to be devastated, that one out of 10,000 queens will make it into the ground to start a new colony. Every little advantage that an organism has can make an enormous difference. The other thing is that natural selection grinds exceedingly small. Natural selection doesn’t allow for foul-ups in an ant colony any more than in a hunter-gatherer society. Real biologists who actually do the research will tell you that they almost never find a phenomenon, no matter how odd or irrelevant it looks when they first see it, that doesn’t prove to serve a function. The outcome itself may be due to small accidents of evolution. And ants are very good for telling us about chemical communication. For instance, one ant may use a heptanone and another may use a methylheptanone as an alarm substance. What’s fascinating is that different species will not intermingle, even though they are so closely related that all that separates them is one isomer of one organic substance. Their gene pools are isolated.
PT: Are there ever accidental spinoffs of evolution? Could there be some traits that really don’t seem to serve an obvious function, but persist anyway?
EO: There are no accidental spinoffs, and there is very little probability that inferior traits will survive. If you told an arm-chair theorist about the tiny differences in chemical communication in ants their inclination would be to say, “Well, it’s an accident, a spin-off. Evolution is full of accidents.” Not when you get down to the nitty-gritty and you find these tiny differences have a major function in separating species. This is the way biology has unfolded through natural history.
PT: But what if one particular variation had such a huge benefit that it generated a huge number of spinoffs and those survived? Like the human brain. The benefit you get from a brain like ours is so large that maybe it can pay for all the spinoffs because of the gain. For instance, is the capacity to make music a spinoff?
EO: Some scientists suggest that music is an accidental spinoff of rhythmicity and speech. But I feel music has a very important role in ritual activity and that being able to join in musical activity, along with dancing, could have been necessary at a very early stage of human culture. It probably served then, as it does today, to bind the society together, and especially during rites of passage and reaffirmation of tribal communion.
PT: But both accounts might be true. It could have been an accidental spinoff, and then the system found a use for it.
EO: That’s entirely possible. We don’t know where rhythm comes from but we do know it has great meaning for us.
PT: What was the big evolutionary trigger that produced the human brain?
EO: That’s the mother of all questions. The paleoanthropologists put a lot of emphasis on climate change. I don’t believe that for a minute, because geological history is full of vast climactic changes, and large numbers of animal species that lived through them unchanged. I think evolution came up with a fairly big animal, primates, with a fairly big brain, and then this animal somehow got on its hind legs. And once it were erect, it had the freedom of hands. It could carry things. It could try out tools. This was the takeoff point. Nothing like that had ever happened before. Climactic change could have speeded the process, but was not critical.
PT: What about dinosaurs? They had hands.
EO: We don’t know why they didn’t go the distance. There was one line of dinosaurs that were big-bodied and big-brained, though not as neurally well-endowed as primates, and they had free hands, but they didn’t take off the way humans did.
PT: Can you talk about taking big risks in science? You’ve called it steering through the blue waters, and abandoning sigh of land.
EO: You either hug the coast or you head for blue water.
PT: Did you start out hugging the coast?
EO: Very much.
PT: When did you shift?
EO: It started in my twenties. I wrote a very controversial paper showing that it’s almost impossible to define a geographic race. If you define a race on skin color, you can do that neatly. Red people here and white people there. But if you throw in noses, you’ve got white people with short noses and long noses and then you throw in another trait and pretty soon you’ve got chaos. I published that when I was 24, and at that pointed I’d genuine controversy and I liked it. Then when I wrote Sociobiology, I knew what it was like to be in blue water during a typhoon!
PT: Did you develop your biggest ideas gradually, or did they hit all at once?
EO: Each time, the whole thing came within minutes. You’ve got the beginnings of a pattern in your mind and at first it doesn’t seem much out of the ordinary, and then you start expanding the implications. And during the few minutes of expanding you sense that the idea may be important. Those moments don’t happen very often in a career but they’re climactic and exhilarating.
PT: In Consilience you said that our essential spiritual dilemma is that we evolved to accept one truth—God—and discovered another—evolution.
EO: And the struggle for men’s souls in the 21st century will be to choose between the two. The transcendentalist view was so powerfully advantageous in early paleolithic and agricultural societies. And if there’s anything disagreeable about secular humanism, it’s that its bloodless. Secular humanists can sit around and talk about their love of humanity, but it doesn’t stack up against a two-millenium-old funeral high mass. I used a phrase called the evolutionary epic back in 1978 to try and convey the grandeur of biology, and it’s beginning to catch on. A colleague of mine speaks of “the sacred depths of nature” to try and evoke that same reverence.
PT: Scientists are trying to capture the awe that religion has, while theologians have had to move a long way from the communities that they’re supposed to represent to make theology consistent with science.
EO: Theology today is really two separate worlds. There’s the world of the fundamentalists who have a set of absolute beliefs that do not need to be justified. They’re armored against any logical argument or evidence, and if logic seems compelling, it’s the voice of the devil. Then there is the theology of the searchers, the thinkers about the meaning of human existence, and they’re trying to accommodate pretty well-rounded views of how the real world works without surrendering the mystery of the Almighty and the need for communal liturgy.
PT: You’ve said that the brain is really a kind of ever shifting network, a republic of responses to information. And yet we walk around with a sense of a core self. Isn’t that peculiar?
EO: I’m aware of you, you’re aware of me. There’s a sense of self. But there is no transcendental center of the brain somewhere that is in control of the machinery, pulling the levers and possessed of the capacity to float free of our mortal coil when that moment comes.
PT: But how does the brain even create that sense of self?
EO: You’ll hear the voice of the neurobiologist emerging from me on this. It’s natural we feel there’s a self because of the body that we’re in. The brain is mapping the world. Often that map is distorted, but it’s a map with constant immediate sensory input. The brain is organized heavily around sensations coming from the body, and that is so intense, so much at the center of conscious experience, including all the input coming from our body, and so it’s seen as the principal protagonist. That’s what the self is.
PT: One of the most precious beliefs of the “self” is that it has free will.
EO: A lot of philosophers and thinkers have believed that the human mind was not based in material reality. They had a vague notion of angelic, transcendent activity that they never could define because, of course, they couldn’t translate it into any materialist terms and make sense. That’s really the basis of the notion of free will, that there is a whole different faculty, probably true for human beings only, a truly human quality that helps lift us up above the animals, somewhere between here and the angels.
PT: But when you talk about free will, you describe it only in the sense that the brain is so complex, so constantly bombarded with input, that it’s able to cascade in any direction at any time. That’s freedom, but not self-determined free will.
EO: There are really two meanings of
free will. One we all agree on is that you have your own mind, you
make your own decisions, your soul is your own. No matter what is
done to you, that’s the one thing that cannot be surrended. Of course,
now we know that with the right pharmaceutical or biochemical manipulation,
you can get people to shift moods, attitudes and maybe even beliefs.
So that view isn’t holding up quite so well anymore. But let’s say
that’s what we mean by free will.
The other kind of free will stops people
cold in their attempt at self-understanding. We don’t know our own
minds. We don’t know all the processes inside and we can’t predict
what kind of responses and decisions we’ll make. And even if we believed
we could, there is so much chaos in the mind brought about by tiny perturbations
or external events. Not even with a gigantic computer could we predict
what any of us sitting at this table will do precisely one hour from now.
PT: So we’re free like the weather.
EO: Or like the wind. We will get up when we are ready to get up. That will be our free will. And we will go out that door and events will happen and we will think about them and make decisions that we can’t predict right now. This thing we’re walking around in is not in complete control. It could do marvelous things. It could encounter disasters.
PT: A world where the brain gives rise to the mind is a world where when we die physically, we’re dead forever. That’s one of the difficult truths of evolutionary biology.
EO: We’ve all descended from a common ancestor, and our genes are moving on into future generations in very closely the same manner as they would if you as an individual were the particular conduit. Looked at that way, you get a sense of near immortality from the human species. Homo sapiens is 500,000 years old, give or take a hundred thousand years. That’s a long time. That’s virtual immortality as far as human beings are concerned. If we last another half-million years, then that’s almost time out of mind, time beyond our personal imagining. However, that notion of immortality is still part of a secularist world view. That’s what humanism really is, you know, concentration on the continuity of the human spirit.
PT: But what do you do as an individual, faced with death? Remember Dylan Thomas’ line, “Do not go gentle into that good night…”
EO: I think what he was telling us was, “Stay healthy, don’t smoke, and be as vigorous and involved as you can.” No…I think that’s what he ought to have told us. I don’t think it would be wise to say that, as the time approaches, you should start raging against death. I don’t think there’s any greater fear of death among atheists or secularists as there is among the devoutly religious. As Francis Bacon has said, “Men fear not death, but the moment of the strike thereof.” If I tell you, “Listen, on May 2nd, 2040, you are going to be executed for having been wrongly accused of murder,” or “On that date you are going to die of a massive heart attack,” that’s distressing, isn’t it?
PT: Right. The date itself doesn’t matter, but knowing the exact moment does.
PT: You call yourself a deist. What do you mean by that?
EO: A deist is a person who’s willing to buy the idea that some creative force determined the parameters of the universe when it began.
PT: And a theist is someone who believes that God not only set the universe in motion, but is still actively involved.
EO: But I’ve been doing a kind of Pascalian waffling as a deist. I think being an atheist is to claim knowledge you cannot have. And to say you’re agnostic is to arrogantly dismiss the whole thing by saying that it’s unknowable. But a provisional deist is someone like myself who leaves it open. You see, evolutionary biology leaves very little room for a theistic God. I’d like it to be otherwise. Nothing would delight me more than to have real proof of a transcendental plane.
PT: Why?
EO: If the neurobiologists came through with enough evidence and said, There is another plane, and it is quite conceivable that the individual essence somehow implanted there is immortal, wouldn’t you be happy? I’d be very, very happy. I’d congratulate my colleagues when they went to Stockholm to get the Nobel Prize, and I’d be personally relieved.
PT: Relieved of what?
EO: It would mean that human existence really is exalted and that immortality is a prospect, providing this God is not a God of irony and cruelty who is going to send everybody the other way. That reminds me of an argument I like to give. Maybe God is sorting the saved from the damned, but the saved will be those who have the intellectual courage to press on with skepticism and materialism. They would be His most independent and courageous creations, would they not? Particularly the ones who faced the charges of heresy.
PT: They get to heaven because they still wanted to, even though they believed there was no heaven.
EO: Right.
PT: I would be deeply disappointed if there was a God. The universe looks so stunningly impressive because it can do this trick all by itself. A deity undercuts it.
EO: I understand what you’re saying. That the human soul was self-created in such an astonishing way that we’re only just beginning to understand.
PT: A universe that needs a push to get it right every now and then—that’s just a second class universe.
EO: So the universe that made itself after it got started, however it got started, is a first class universe. This is what I say, actually, in Consilience. We’re free, thank God.
PT: Or thank something.
EXCERPT FROM CONSILIENCE (check with publisher)
For many the urge to believe in transcendental
existence and immortality is overpowering. Transcendentalism, especially
when reinforced by religious faith, is psychically full and rich; it feels
somehow right. In comparison empiricism seems sterile and inadequate.
That is why, even as empiricism is winning the mind, transcendentalism
continues to win the heart. Science has always defeated religious
dogma point by point when the two have conflicted. But to no avail.
In the United States there are fifteen million Southern Baptists, the largest
denomination favoring literal interpretation of the Christian Bible, but
only five thousand members of the American Humanist Association, the leading
organization devoted to secular and deistic humanism…
Science has taken us very far from the personal
God who once presided over Western civilization. It has done little
to satisfy our instinctual hunger…The essence of humanity’s spiritual dilemma
is that we evolved genetically to accept one truth and discovered another.
Is there a way to erase the dilemma, to resolve the contradictions between
the transcendentalist and empiricist world views?
No, unfortunately, there is not…For centuries
the writ of empiricism has been spreading into the ancient domain of transcendentalist
belief, slowly at the start but quickening in the scientific age.
The spirits our ancestors knew intimately first fled the rocks and trees,
then the distant mountains. Now they are in the stars, where their
final extinction is possible. But we cannot live without them.
People need a sacred narrative…
The true evolutionary epic, retold as poetry,
is as intrinsically ennobling as any religious epic. Material reality
discovered by science already possesses more content and grandeur than
all the religious cosmologies combined.
