What Was God Thinking? Science Can't Tell
By ERIC CORNELL
Scientists, this is a call to action. But also one to inaction. Why am I the messenger? Because my years of scientific research have made me a renowned expert on my topic: God. Just kidding. You'll soon see what I mean. Let me pose you a question, not about God but about the heavens: "Why is the sky blue?" I offer two answers: 1) The sky is blue because of the wavelength dependence of Rayleigh scattering; 2) The sky is blue because blue is the color God wants it to be.
My scientific research has been in areas connected to optical phenomena, and I can tell you a lot about the Rayleigh-scattering answer. Neither I nor any other scientist, however, has anything scientific to say about answer No. 2, the God answer. Not to say that the God answer is unscientific, just that the methods of science don't speak to that answer.
Before we understood Rayleigh scattering, there was no scientifically satisfactory explanation for the sky's blueness. The idea that the sky is blue because God wants it to be blue existed before scientists came to understand Rayleigh scattering, and it continues to exist today, not in the least undermined by our advance in scientific understanding. The religious explanation has been supplemented--but not supplanted--by advances in scientific knowledge. We now may, if we care to, think of Rayleigh scattering as the method God has chosen to implement his color scheme.
Right now there is a federal trial under way in Dover, Pa., over a school policy requiring teachers to tell students about "intelligent design" before teaching evolution. The central idea of intelligent design is that nature is the way it is because God wants it to be that way. This is not an assertion that can be tested in a scientific way, but studied in the right context, it is an interesting notion. As a theological idea, intelligent design is exciting. Listen: If nature is the way it is because God wants it to be that way, then, by looking at nature, one can learn what it is that God wants! The microscope and the telescope are no longer merely scientific instruments; they are windows into the mind of God.
But as exciting as intelligent design is in theology, it is a boring idea in science. Science isn't about knowing the mind of God; it's about understanding nature and the reasons for things. The thrill is that our ignorance exceeds our knowledge; the exciting part is what we don't understand yet. If you want to recruit the future generation of scientists, you don't draw a box around all our scientific understanding to date and say, "Everything outside this box we can explain only by invoking God's will." Back in 1855, no one told the future Lord Rayleigh that the scientific reason for the sky's blueness is that God wants it that way. Or if someone did tell him that, we can all be happy that the youth was plucky enough to ignore them. For science, intelligent design is a dead-end idea.
My call to action for scientists is, Work to ensure that the intelligent-design hypothesis is taught where it can contribute to the vitality of a field (as it could perhaps in theology class) and not taught in science class, where it would suck the excitement out of one of humankind's great ongoing adventures.
Now for my call to inaction: most scientists will concede that as powerful as science is, it can teach us nothing about values, ethics, morals or, for that matter, God. Don't go about pretending otherwise! For example, science can try to predict how human activity may change the climate, but science can't tell us whether those changes would be good or bad.
Should scientists, as humans, make judgments on ethics, morals, values and religion? Absolutely. Should we act on these judgments, in an effort to do good? You bet. Should we make use of the goodwill we may have accumulated through our scientific achievements to help us do good? Why not? Just don't claim that your science tells you "what is good" ... or "what is God."
Act: fight to keep intelligent design out of science classrooms! Don't act: don't say science disproves intelligent design. Stick with the plainest truth: science says nothing about intelligent design, and intelligent design brings nothing to science, and should be taught in theology, not science classes.
My value judgment is that further progress in science will be good for humanity. My argument here is offered in the spirit of trying to preserve science from its foes--but also from its friends.

Pois. Essa é a simpática tese dos "Nonoverlapping Magisteria", no artigo descrita sem as peneiras intelectuais do Gould. Há uma outra versão também pouco académica da mesma postura: "não pregues na minha sala de aula que em não pensarei na tua igreja". Por mim, aceito a ideia dos "Nonoverlapping Magisteria". Mas gostaria que o papa deixasse Darwin em paz. Como se já não bastasse ter os evangelistas à perna...
A pope for our times: why Darwin is back on the agenda at the Vatican
William Rees-Mogg
IN THE mid-1980s I was a member of a Vatican body with the impressive title International Committee of the Pontifical Council for Culture. Each year we had a meeting with Pope John-Paul II; on one occasion he gave us lunch and served a light white wine from, I think, a papal vineyard.
The other members of the committee included a splendid Ibo lady, the head of the Catholic Women’s Movement in Nigeria, an Indian nun, a Japanese Jesuit and a Francophone president of an African nation who believed that French culture and a sound classical education would be the best answer to Africa’s educational problems. I enjoyed our discussions, which were almost always held in French.
The idea, which came from the Pope himself, was far-sighted. We foresaw what has subsequently been called the “clash of civilisations”; we tried to relate that conflict to the widely differing cultures of the billion members of the Roman Catholic Church. We discussed the impact of particular developments in modern science but so far as I can remember we did not try to deal with the central problem of the relationship between science and religion; that seems to have come now.
Our chairman was Cardinal Paul Poupard, an admirable example of the cultivated French intellectual in the Roman Curia; he is still the head of the Pontifical Council for Culture. Whether the council still has an international committee I do not know, since I left it nearly 20 years ago. Last week the cardinal was giving a press conference before a meeting in Rome of scientists, philosophers and theologians; this week they will be discussing the difficult subject of infinity. Cardinal Poupard had a beautifully trained French mind and inner loyalty to the Catholic faith. Nothing he says is said without careful thought. At the press conference he was discussing the issue of evolution, which is the critical dividing line between science and religion. Charles Darwin’s On the Origin of Species shook religious belief when it was first published in 1859 in a way that Isaac Newton’s equally important Principia had not shaken the faith of 1687.
In The Times Martin Penner reported the cardinal’s argument. He had said that the description in Genesis of the Creation was “perfectly compatible” with Darwin’s theory of evolution, if the Bible were read properly. “Fundamentalists want to give a scientific meaning to words that had no scientific aim.”
He argued that the real message of Genesis was that the Universe did not make itself, and had a creator. “Science and theology act in different fields, each in its own.” In Rome, the immediate reaction was that this was a Vatican rejection of the fundamentalist American doctrine of “intelligent design”. No doubt the Vatican does want to separate itself from American creationists, but the significance surely goes further than that. This is not another Galileo case; the teachings of the Church have never imposed a literal interpretation of the language of the Bible; that was a Protestant mistake. Nor did the Church condemn the theory of evolution, though it did and does reject neo-Darwinism when that is made specifically atheist.
Indeed, one can go back nearly 1,500 years before Darwin and find St Augustine of Hippo, the most commanding intellect of all the early doctors of the Church, teaching a doctrine of evolution in the early 5th century. In one of his greatest works, De Genesi ad Litteram, he stated that God did not create an organised Universe as we see it now, but in the beginning created all the elements of the world in a confused and “nebulous” mass. In this mass were the mysterious seeds of the creatures who were to come into existence.
Augustine’s thought does therefore contain the elements of a theory of evolution, and even a genetic theory, but does not have natural selection. St Augustine has always been orthodox. He did not foresee modern science in AD410, but he did have an extraordinary grasp of the potential evolution of scientific thought. Cardinal Poupard’s address to the journalists should not be seen as a matter of the Roman Church changing its mind and accepting Darwin after 145 years.
It is a precautionary statement, distancing the Church from the American attack on Darwinism that Rome considers to be neither good science, nor good theology. It will also be taken as an indication of the priorities of the present Pope Benedict XVI.
His critics had expected him to be more conservative than his predecessor. I tended to share this expectation myself, but refrained from expressing it because new leaders always surprise one; they move in directions no one had previously foreseen. We should have been more conscious of differences between the national traditions of the Catholic Church in Poland and in Germany. The Polish Church, which trained John-Paul II, had always combined conservative theology with support for the national claims to liberty. The German Church has always been challenged by the modernism of German theology.
In the 16th century Germany was the region where the Reformation happened. German theologians on the Roman Catholic side had to understand the arguments of the Reformers if they were to reply to them. In the 18th century Germans were fully exposed to the French Enlightenment. In the 19th century they were exposed to German philosophers such as Hegel, and to the challenge of German biblical scholarship. Modernism itself in the late 19th century had a great influence on German Catholic opinion.
All these arguments are well understood by Benedict XVI, because so many of them are German arguments.
Cardinal Poupard’s statement clarified the acceptance of Darwinism and rightly asserted that religious belief is compatible with the theory of evolution. He also gave a further indication that the mindset of Benedict XVI may be a good deal more modern than had been expected. One should have foreseen that with a German pope. The German Church has a strong tradition of theological inquiry in which Benedict XVI has been educated.

Absolutamente. Quando um cientista afirma que "design inteligente" e' falso, no fundo está a cometer o mesmo erro que as pessoas do outro lado da barricada fazem; ou seja confundir alhos com bugalhos.
