Education and the Theory of Evolution
One of the jobs of the U.S. Conference of Catholic Bishops is to look at the various threads of American popular culture and to identify those that should be actively opposed by Catholics. According to a recent article at catholicnews.com, the U.S. bishops are starting to worry about a particular adverse influence of fundamentalist Protestantism on Catholics. The worrisome thing, from the Church hierarchy's point of view, is the occasional Catholic's public insistence---in the face of scientific facts that militate against it---on a literal interpretation of the creation accounts in Genesis. A child, of course, is not harmed by his learning the creation story, even though he is capable only of understanding it at the literal level. Even an adult who is ignorant of the observational evidence and who has no occasion for public discussion of things scientific is not harmed by imagining the creation stories literally to be true. The stories get some points, like God's creating only good things and man's responsibility for the presence of all evil in the physical universe, right on. However, for the Catholic, who is aware of the real scientific evidence and who has some measure of responsibility publicly to discuss the issue, to insist on a merely literal interpretation of the creation narratives is wrong; such a Catholic misrepresents the Church's position.
This subject is particularly interesting to me. I have posted elsewhere in this blog comments about religion, science, and evolution. Moreover, I have indicated that my serious consideration of the Church as a true authority began in my detailed investigation, ten or so years ago, of the Church's teaching on evolution. The debate over the teaching of evolutionary theory in the public schools is a debate that seems never to die for very long. And it is back in the headlines again:
In January, the public school board in Cobb County, Ga., voted to appeal a federal judge's order to remove stickers on science textbooks which said that "evolution is a theory, not a fact."
This quote, in my view, highlights the main reason for the continuing debate: Almost everybody is confused. In the midst of confusion, even more than in the midst of heartfelt disagreement, nothing can be settled. At least when there is a clear disagreement, everyone can see it, and there is little sense in trying to clarify it further. Unfortunately, the public debate over evolution is mired in confusion about what science actually is, even among practicing scientists, many of whom have never bothered to study the philosophy and history of modern science.
On the one hand, despite what the general public might have you believe, my agreement that "evolution is a theory, not a fact" does not make me a member of the anti-evolution camp. No right-thinking person actually believes that a particular evolutionary theory is true, just as no right-thinking person actually believes that general relativity is true. Rather, the person with his head on straight recognizes that, at present, for each proper subset of the available paleontological data there is some evolutionary theory that is the best theory to fit those data. Moreover, no matter how unlikely it might now seem, some future evidence could rule out the very idea of evolution as a useful concept.
The point is that no scientific theory can ever be proved true, and, if history is any guide, every scientific theory will eventually be proved false.
By scientists.
For example, Lamarck's theory of evolution was proved false. So was Darwin's theory of universal gradual evolution. So was Newtonian mechanics.
On the other hand, there are scientific facts. Every peer-reviewed, published, repeatable experimental result or observation is a scientific fact. And it's the pesky scientific fact that always eventually spells doom for any given theory, like a cosmology based on a literal interpretation of Genesis.
Fortunately, according to the Church's position, the scientific anthropological community has the right authority to say what theory best fits the scientific facts about the origin of the human body. So the Church's position is consistent with modern science because the Church recognizes the right authority of the scientific community. The Church's position is also consistent with the Apostolic Tradition, according to which man is certainly not, in his entirety, a product of evolution: The human person is more than just a body. That is---the religious claims of the atheist notwithstanding---the human person has an immaterial soul, and the human soul certainly did not evolve, even if the human body did evolve.
Anyway, if you have read this far, then I thank you for putting up with me. My hope is to make clear and explicit what is usually, in public debate on this issue, expressed only vaguely and implicitly. My duty as a Catholic, following the direction of the U.S. bishops, is to represent the Church fairly, clearly, and precisely. I should very much be interested in any discussion on the matter, though I don't really expect much in this low-traffic blog. :^)

One need only consider the "Gravity Losing Its Pull" item that Curtis posted in December to see an example of what may turn out to be one of the those pesky scientific facts that overturns the current theory of gravity. Folks are really baffled by these data. If they turn out to be "facts" and not "artifacts" (i.e. systematic errors due to the way the data have been processed), then the implications are conceivably huge.

I come from a different viewpoint on this debate than most of you because I grew up in a very non-religious household. I only attended a church about a dozen times during my childhood all the way up to my teenage years. I learned the evolution theory long before I had ever heard of the Genesis/Adam and Eve theory.
Coming from that point of view, I found the Adam and Eve theory to lack credulity even as a small-minded lad of 10 or 11. It seemed like a fairy tale much like the rest of the bible did to me.
I do not write that to insult anyone who believes in the teachings of the bible. It's just the very simple way that I have always viewed that particular theory.
Tom is right in that I have always trusted the "science" behind the evolution theory and have never fully questioned or researched it to look for possible gaps or faults in that particular theory. It's just something I have always assumed to be true.
As for the continuing debate including the textbook stickers being imposed by Evangelical groups, I view that issue much as I do with any instance of religion creeping into education at school. I would rather the teachings of the bible be left in church and out of the secular classrooms.
Who's to say "your Bible" is better or more accurate than "my Koran" or "your neighbor's Talmud"? If I choose to send my child to public school, I would like religion to remain out of the curriculum as much as possible.
Now, you'll have to excuse me. I just got struck by a bolt of lightning and need to go to the hospital for immediate medical assistance.

Curtis, I agree that religious belief should have as small an influence as possible on a science curriculum. There are, however, two subtle---but serious---problems with the assertion that religious belief should have no influence on the curriculum.
The first is that a religious belief of a sort lies at the very heart of science itself. We tend not to see this because the theories that we have developed some three hundred years into the modern-science game are so very good at predicting how many everyday processes go. It seems obvious that science is a useful enterprise, if not for discovering great truth---remember, scientific theory can never be proved true---then at least for the advancement of practical engineering. But this was not always so. It is no accident that modern science developed in the Christian West. Especially after the work of St. Thomas of Aquinas, who convincingly demonstrated that all true knowledge is ultimately based on sense experience, there was a growing confidence that the mind of man, equipped with certain tools and the belief that the physical universe is the creation of a rational Mind, could make logical, consistent sense of careful observations. From St. Thomas in the 12th century until just after Galileo was man's final sprint toward modern science. Even Galileo screwed up by thinking that a physical theory could be proved true; that's the core reason for which he got in trouble with the Church, which insisted that Galileo present his ideas as one possible explanation, and Galileo refused to do this. Anyway, even today we can still see a bit of faith in the scientific enterprise. Our best theories still assume that the same rules will apply tomorrow as applied yesterday, and that is quite a bit like religious faith.
The second and more serious problem with the complete exclusion of religious ideas from the science curriculum is that the religious beliefs of the atheist often sneak into the science classroom under the guise of "science". For example, a biology textbook might assert that the human being is a mammal. Implicit (and even explicit in certain textbooks) is the idea that the human being is merely a mammal. Now that assertion is a religious assertion, or at least a non-scientific philosophical assertion that is inconsistent with Christianity. There are at least three good ways to see that it is at least non-scientific:
(a) Although there exist some quite good (in the predictive sense) theories of animal behavior, there is no good theory to explain human behavior, especially where that behavior is particularly interesting. Moreover, there is no physical theory of thought.
(b) Penrose has shown that human thought is non-algorithmic. This means not only that it is impossible to make a computer program that can think but also that no merely physical basis for thought (theory of thought) can be constructed within the framework of current physical theory (general relativity and quantum mechanics).
(c) The typical (Copenhagen) interpretation of quantum mechanics, which is the standard curriculum in physics graduate schools, suggests that there is something supernatural in the observer (human or otherwise) who causes by his observation the collapse of a wavefunction.
What we really need in the science classroom is some good teaching on the philosophy of science:
1. that a scientific theory can never be proved true,
2. that a scientific fact is a repeatable observation,
3. that different theories can fit the facts,
4. that a theory is scientific only if it can be proved false,
5. that the community of scientists who publish peer-reviewed articles on a particular subject have the right authority to say what the facts are,
6. that such a community also has the authority to say what the best theory to fit the facts is,
7. that science makes certain assumptions, such as the principle of the uniformity of nature and the above points,
8. that it is by no means clear that the conceiver of science can himself essentially be described by a scientific theory, regardless of what the atheists would have you believe.

It seemed like a fairy tale much like the rest of the bible did to me.Your use of "fairy tale" is apt in a sense for the first few chapters of Genesis. From the creation narratives, through the Garden of Eden, through the story of Noah, and up to the Tower of Babel, the story is all set timelessly, as "in the beginning" or "once upon a time". Unlike a "fairy tale", however, the stories at the beginning of Genesis are really true in that they convey truths about man, truths that have been true about him since the beginning, truths that will be true about him for all time. These truths concern not only man's inner nature but also his proper relationship to the natural world and his proper relationship to the Creator of the universe.
After the Tower of Babel, however, and through the end of the Torah (the first five books of the old testament) the narrative becomes more or less actually historical, literal, if you will, but not by the standards of a modern history text.

If the sticker says, "Evolution is a theory and not a fact," then the sticker is basically correct. It doesn't matter if the sponsor of the sticker is religious fanatic or not. One might feel the impulse to oppose such a sticker merely because one knows that a religious fanatic is sponsoring it, but a moment of cool thought reveals that the sticker itself only promotes right thinking. It does not represent "teachings of the bible," but it does represent a key idea in the philosophy of science.
If we resist the words of the sticker, then we regress four hundred years and make Galileo's mistake all over again.

If we're going to allow that sticker on those textbooks, then why stop there? Why not put stickers that dispute or challenge every "theory" included in the science textbooks. Pretty soon, you will have so many stickers that there will be no more room for the actual text in the books. Either that or students will be so confused, they won't know what to believe.
It feels like one of those "gateway" issues to me. If you give an inch, a mile will be taken.

You raise a good point about singling out evolution. Better would be to put one sticker in every textbook:
"No scientific theory can be proved true. The only scientific truth is the peer-reviewed, published scientific observation."
We need that one, or something like it. If I judge by looking at discussions of science in the media, then our schools need some kind of help (stickers, philosophy of science boot camps, or whatnot) to drill this into the population.

On that last point, we can definitely agree.
