SPIEGEL Interview with Evolution Philosopher Daniel Dennett: "Darwinism Completely Refutes Intelligent Design"

Intelligent Design is once again making headlines in the United States. But what is the attraction? Daniel Dennett spoke with SPIEGEL about the attraction of creationism, how religion itself succumbs to Darwinian ideas, and the social irresponsibility of the religious right in America.

Can Darwinism explain the creation of the universe as well?

SPIEGEL:

Professor Dennett, more than 120 million Americans believe that God created Adam our of mud some 10,000 years ago and made Eve from his rib. Do you personally know any of these 120 million?

Dennett: Yes. But people who are creationists are usually not interested in talking about it. Those who are actually enthusiastic about Intelligent Design, though, would talk endlessly. And what I learned about them is that they are filled with misinformation. But they've encountered this misinformation in very plausible sources. It’s not just their pastor that tells them this. They go out and they buy books that are published by main line publishers. Or they go on Web sites and they see very clever propaganda that is put out by the Discovery Institute in Seattle, which is financed by the religious right.

SPIEGEL: In the center of the debate is the theory of evolution. Why is it that evolution seems to produce much more opposition than any other scientific theory such as the Big Bang or quantum mechanics?

Dennett: I think it is because evolution goes right to the heart of the most troubling discovery in science of the last few hundred years. It counters one of the oldest ideas we have, maybe older even than our species.

SPIEGEL: Which is what exactly?

Dennett: It's the idea that it takes a big fancy smart thing to make a lesser thing. I call that the trickle-down theory of creation. You'll never see a spear making a spear maker. You'll never see a horse shoe making a blacksmith. You'll never see a pot making a potter. It is always the other way around and this is so obvious that it just seems to stand to reason.

SPIEGEL: You think this idea was already present in apes?

Dennett: Maybe in Homo Habilus, the handyman, who began making stone tools some 2 million years ago. They had a sense of being more wonderful that their artifacts. So the idea of a creator that is more wonderful than the things he creates is, I think, a very deeply intuitive idea. It is exactly this idea that promoters of Intelligent Design speak to when they ask, 'did you ever see a building that didn't have a maker, did you ever see a painting that didn't have a painter.' That perfectly captures this deeply intuitive idea that you never get design for free.

SPIEGEL: An ancient theological argument...

Dennett: ... which Darwin completely impugns with his theory of natural selection. And he shows, hell no, not only can you get design from un-designed things, you can even get the evolution of designers from that un-design. You end up with authors and poets and artists and engineers and other designers of things, other creators -- very recent fruits of the tree of life. And it challenges people's sense that life has meaning.

SPIEGEL: Even the spirit of humans -- his soul -- is produced in this manner?

Dennett: Yes. As a multi-cellular, mobile life form, you need a mind because you have to look out where you are going. You have got to have a nervous system, which can extract information from the world fast and can refine that information and put it to use quickly to guide your behavior. The basic problematic for all animals is finding what they need and avoiding what could hurt them and doing it faster than the opposition. Darwin understood this law and understood that this development has been going on for hundreds of millions of years producing ever more android minds.

SPIEGEL: But still, something out of the ordinary happened when humans came along.

Dennett: Indeed. Humans discovered language -- an explosive acceleration of the powers of minds. Because now you can not just learn from your own experience, but you can learn vicariously from the experience of everybody else. From people that you never met. From ancestors long dead. And human culture itself becomes a profound evolutionary force. That is what gives us an epistemological horizon and which is far, far greater than that of any other species. We are the only species that knows who we are, that knows that we have evolved. Our songs, art, books and religious beliefs are all ultimately a product of evolutionary algorithms. Some find that thrilling, others depressing.

SPIEGEL: Nowhere does evolution become so apparent than in the DNA code. Nevertheless, those who believe in Intelligent Design find the DNA code less problematic than the ideas of Darwin. Why is that?

Dennett: I don't know, because it seems to me that the very best evidence we have for the truth of Darwin's theory is the evidence that arrives every day from bioinformatics, from understanding the DNA-coding. The critics of Darwinism just don't want to confront the fact that molecules, enzymes and proteins lead to thought. Yes, we have a soul, but it's made up of lots of tiny robots.

SPIEGEL: Don't you think it's possible to leave life to the biologists, but let religion take care of the soul?

Dennett: That's what Pope John Paul II was demanding when he issued his oft-quoted cyclical in which he said that evolution was a fact, but he went right on to say: except on the matter of the human soul. That might make some content, but it is just false. It would be just as false to say: Our bodies are made up of biological material, except, of course, the pancreas. The brain is no more wonder tissue than the lungs or the liver. It's just a tissue.

SPIEGEL: Darwin's ideas have been misused by racists and eugenicists. Is this also one of the reasons that Darwinism is so energetically attacked?

Dennett: Yes. I think the gentler way of putting it is that the Darwinian idea is very simple -- you can explain it to somebody in a minute. But for that very reason, it is also extremely vulnerable to caricature and misuse. I very patiently teach my students the basics of evolutionary theory and then I have to go back and clean up after myself, because they get very enthusiastic about it and they keep falling into these misunderstandings. Darwinism is mind candy, it's delicious. But the thing is, having too much candy can distract from the truth. And that can play into the hands of people who are racist or sexist. So you have to maintain a sort of intellectual hygiene at all times.

SPIEGEL: It seems that everything -- from adultery to rape to murder -- is being analyzed in the light of evolution these days. How can one separate serious research from the candy?

Religion must be incomprehensible to be successful, says Dennett.

Religion must be incomprehensible to be successful, says Dennett.


Dennett: You have to be a meticulous gatherer of the relevant facts and you have to marshal those facts in such a way that you have a testable hypothesis that could actually be confirmed or disproved. That's what Darwin did.

SPIEGEL: Your colleague Michael Ruse has accused you of stepping out of the field of science and into social science and religion with your theories. He's even said you are inadvertently aiding the Intelligent Design movement as a result.

Dennett: Michael is just trying to put the implications of Darwin's insights into soft focus and to reassure people that there is not as much conflict between the perspective of evolutionary biology and their traditional ways of thinking.

SPIEGEL: And what about the accusation that you are aiding Intelligent Design?

Dennett: There is probably an element of truth to it. I've just finished writing a book in which I look at religion from the perspective of evolutionary biology. I think you can, should, and even must take this route. Others say 'no, hands off! Just don't let evolution get anywhere near the social sciences.' I think that's terrible advice. The idea that we should protect the social sciences and humanity from evolutionary thinking is a recipe for disaster.

SPIEGEL: Why?

Dennett: I would give Darwin the gold medal for the best idea anybody ever had. It unifies the world of meaning and purpose and goals and freedom with the world of science, with the world of the physical sciences. I mean, we talk about the great gap between social science and natural science. What closes that gap? Darwin -- by showing us how purpose and design, meaning, can arise out of purposelessness, out of just brute matter.

SPIEGEL: Is Darwinism at work every time something new is created? Even at the creation of the universe for example?
