The court and both parties in Kitzmiller v. Dover Area School District battled about whether intelligent design was science or religion. None of them showed any interest in the right answer – a little (or a lot) of both.
The experts who testified in favor of ID insisted that, as far as their theory went, the intelligent designer might be someone other than God. But come on. If you discovered the intelligent designer of every life form on the planet (including you), what would you call him? Probably not Uncle Zeke.
The Dover court is wrong, however, when it says that anything that “implicates” religion also “endorses” it. The Constitution does not forbid all discussion of religion in the schools, especially when the proponents of religious ideas do not rely on faith or revelation or claim to “believe it because it is absurd.” The proponents of ID look to the evidence of their senses and respond on empirical grounds to a view of the world sharply different from their own, one that the public schools are already teaching.
Opponents of ID might ask themselves whether, if they did not regard ID’s scientific claims as junk – if they concluded that ID posed a serious intellectual challenge to Darwinism – they would nevertheless forbid discussing it in the schools because it is religious. Would the establishment clause demand the presentation of only one side of a genuinely debatable issue and impose the resulting ignorance on students? Whether ID should be banished from the schools because it’s about God is a different issue from whether it should be banished because it’s nonsense.
The Dover court argues that ID is “a religious and not a scientific proposition” because it does not follow “the ground rules of science” or the “scientific method.” As Einstein observed, however, "The whole of science is nothing more than a refinement of everyday thinking." Human knowledge – all of it except the intuitive – consists of perceived patterns in experience. Pattern seekers in science and every other field use all the mental techniques that God or natural selection gave them. The claim of a distinctive “scientific method” is as conceited as my own profession’s claim of a distinctive method of “legal” reasoning.
The court argues that ID does not follow the ground rules of science because it is not “testable” or “falsifiable.” Like most writers on the subject, the court invokes the image of science associated with Karl Popper – a view still endorsed by many scientists but rejected for good reason by most philosophers of science. W. V. Quine (and before him Pierre Duhem) showed that paradigm-preserving explanations are always available. New data never require the abandonment of a particular belief when we are willing to sacrifice other beliefs. In that sense, no scientific proposition is ever falsifiable.
To be sure, the preservation of a proposition in the face of new experimental or other data may require the revision of so many other beliefs (or of such core beliefs) that, in practical terms, the proposition is effectively falsified. More important than the ultimate analytic falsity of the Popperian picture is the inaccuracy of that picture as a description of everyday science. As the Dover court recognized, “[R]eal gaps in scientific knowledge . . . indisputably exist in all scientific theories.” In practice, scientists do not abandon a paradigm whenever any contradictory evidence appears. Nowhere is the weakness of the Popperian model more evident than in evolutionary biology, the land of the “just so” story.
If a peacock’s tail were brown and blended nicely into the background, the tail’s colors would illustrate how random mutation allows genetically fortunate birds to elude predators. The colors would show natural selection at work. And when the male peacock’s tail is iridescent and multi-colored and stands out against the background, the tail’s bright colors signal the hen that the cock is resistant to parasites and desirable as a mate. The bright colors thus show natural selection at work. In other words, heads I win, tails you lose. Show a Darwinist an anomaly, and he will devise a story that fits it to his theory. As long as he can do that, the theory of natural selection cannot be falsified. New bits of evidence can merely shift the plausibility of this theory in one direction or the other.
When commentators on my December 21 post challenged other commentators to specify what evidence they would accept as falsifying Darwinism, the responses cited J. B. S. Haldane’s remark that discovering a rabbit fossil in a pre-Cambrian rock would do it. But the order of life forms in the fossil record indicates only of the emergence of some forms before others, a fact that ID does not dispute. What is contested is whether this ordering was the product of random selection or intelligent design.
Again, some questions should be disaggregated. “Evolution” is not at issue. None of the principal spokesmen for intelligent design dispute “microevolution.” Scientists can breed fruit flies so that they have great big heads or teeny tiny heads, and when birds eat all the black moths, only the white moths will have offspring.
“Macroevolution” or “speciation” is somewhat more problematic. Setting aside the strange world of microbes, the evolution of one species into another does not appear to have happened in the laboratory, and the Cambrian explosion brought the sudden appearance of life forms without obvious precursors in the fossil record.
Many proponents of intelligent design question macroevolution, but I don’t. Even if no obvious precursors of the first rabbit appear in the fossil record, it seems more plausible that the first rabbit had a mommy and a daddy than that God put the creature on the earth fully formed. Evolution was a familiar theory before Charles Darwin, and the idea raised few religious hackles. As I see it, the most important issue posed by intelligent design is neither microevolution nor macroevolution but Darwin’s explanation of how it happened. Is a mindless process driven by random mutation adequate to explain all life forms, or might the process of creation have a purpose?
Popperian images of science to the contrary notwithstanding, paleontologists rarely perform experiments or make predictions. They can’t. The dinosaurs are all dead. These scientists simply examine the fossil record in an effort to infer how life forms developed. Inference to the best explanation is the name of the game, and the proponents of intelligent design want to play.
The champions of intelligent design start with ordinary inference on their side. No biologist denies that, on first inspection, complex life forms appear to be designed. But ordinary inference can be wrong. I cannot be confident that the sun goes around the earth just because it seems that way at first glance.
The Dover court declares that “arguments against evolution are not arguments for design” and that “irreducible complexity is a negative argument against evolution, not proof of design.” In determining whether natural selection offers a more convincing explanation of biological complexity than ordinary inference, however, anomalies and gaps in the theory of natural selection obviously matter. Astronomers made the case for Copernican astronomy by pointing to the epicycles Ptolemaic astronomy required. If a Ptolemaic astronomer had been able to show that Copernican astronomy required equally inelegant stretches, ordinary inference probably would have triumphed, and the earth would have remained at the center of the planetary system.
The Dover court responds to the argument that “we infer design when we see parts that appear to be arranged for a purpose” by saying, “Expert testimony revealed that this inductive argument is not scientific.” Induction (pattern recognition), however, is what science is about. It is always useful to see whether a perceived pattern can be shaken or reinforced by experimental or other previously unobserved data, but if either experimentation or prediction were an essential part of the scientific enterprise, many notable scientists would have been drummed from the profession.
The fact that ID has ordinary inference on its side may justify its focus on the anomalies of natural selection and may explain why ID scientists do less laboratory research and publish less in peer reviewed journals than some Darwinist biologists. The academic role of the ID biologist is essentially negative – to challenge Darwinist explanations and look for phenomena that the Darwinists cannot explain or, more realistically, can explain only by stretching. This critical role (“look at all those epicycles”) cannot fairly be excluded from science.
The court writes that “ID violates the centuries-old ground rules of science by invoking and permitting supernatural causation,” that “since the scientific revolution of the 16th and 17th centuries, science has been limited to the search for natural causes,” and that “rigorous attachment to ‘natural’ explanations is an essential attribute to science by definition and by convention.” If the court’s point were simply that science excludes faith, mysticism, revelation, and appeals to unchallengeable authority, the proponents of ID would agree. But nothing can be said for a convention that excludes intelligent design by fiat if that is where the evidence leads.
The exclusion of ID from science “by definition and by convention” becomes particularly unfair when ID and natural selection provide competing explanations of the same phenomena. The court, however, insists that the perception of a conflict between natural selection and intelligent design is a “contrived dualism.” My third and final post on the Dover case will consider this “compatibilist” claim.
Fair enough, Kimball -- I agree with you, but Deborah has been exceedingly rude to me. She's made it clear that there's no point in arguing with her. So while I think her arguments can be defeated, I don't see the point in trying to defeat them. She has been marginally less abusive to you, so it might make sense for you to engage her. But I can only be insulted so many times before I lose interest in continuing the "discussion."

Government will always contradict religious views to some extent by not establishing or honoring them, as it should. However, home schooling is one out here. But to address your concern directly, the perspective of many that evolution is hokum, natural selection is nonexistent, the earth is 10,000 years old and we were placed here as sentient beings is just repudiated by too much evidence from the natural world, just as is the religious view that the our earth is the center of not only our solar system, but also the whole universe as well. While evolution theory is not without its present difficulties and gaps and our understanding is as yet incomplete (matters which can and should be also taught, along with the limitations on scientific knowledge), it is demonstrably right in regard to too much to be discarded as science unworthy to be taught. Moreover, the Cathloic Chruch accepts evolution as not being inconsistent with Church doctrine, contending that Genesis may not be read literally , but must to understood allegorically, because too much good science repudiates a literal reading.

"...but simply posites it as an unprovable alternative to coincidence..."
Kimball, I'm sure that, as a trial lawyer, you're used to using language precisely. What coincidence are you referring to? What two or more unlikely events seem coincidental to you?

To pick one example more or less at random from the laundry list of scientists making comments that superficially and tenuously appear at a glance to support something like ID - George Sim Johnson characterizes evolutionary theory as saying that life arose and diversified randomly.
It does no such thing. Natural selection is not random. Nobody with any familiarity at all with natural selection would call it random. Certainly not trained biologists (except for a few inevitable exceptions on the fringe). This is simply a baseless confusion.
Posted by: Tom Castle | January 09, 2006 at 08:52 AM
Furthermore, many of the quotes in that laundry list address the origination of life, not of diversity. Since evolutionary theory deals with the origin of species, not life itself, those quotes miss the point entirely.

Sir Fred Hoyle, British physicist and astronomer:
"The likelihood of the formation of life from inanimate matter is one to a number with 40,000 nought's after it...It is big enough to bury Darwin and the whole theory of Evolution."
This just proves that a British physicist and astronomer can be just as ignorant of evolutionary theory as anybody else (I did note that he's not described as a British biologist, which explains the confusion). The theory of evolution doesn't deal with the "spark of life" at all. Period.

More shoddy thinking:
"There was no primeval soup, neither on this planet nor on any other, and if the beginnings of life were not random, they must therefore have been the product of purposeful intelligence.
"The chance that higher life forms might have emerged through evolutionary processes is comparable with the chance that a tornado sweeping through a junk yard might assemble a Boeing 747 from the material therein."
Since damage from a tornado is more or less random, and evolutionary processes are not, this quote again misses the point entirely and could be easily dispatched in a courtroom setting by any trained biologist.
The formation of snowflakes isn't random, either. Snowflakes are incredibly complex and strike most people who look at them closely as miraculously beautiful and, well, intelligently designed. Does that mean we should throw out everything we know about snowflake formation and say, instead, that God builds snowflakes?
Fred Hoyle hopefully knows more about planet formation than biology. I'd love to ask him under oath how planets formed...specifically, how Saturn formed. It's a beautiful planet with amazing rings around it. People marvel at its complexity and beauty when they look at it.
And I'd as Dr Hoyle what our best scientific understand is of how those rings and the planet they encircle formed. And I doubt *very much* that he'll reply by saying, "God built those rings. They just appeared one day because God told them to."
Does anybody seriously doubt this? Planet formation is *neither* random nor intelligently designed. So Hoyle's random-or-designed dichotomy quoted above is false and absurd on its face.
I agree with Kimball, however, that it would be quite productive to address these arguments in court, under oath.

What would an "ID experiment" look like? If a group of scientists went into a lab and designed a flagella would that mean that all flagellum were the product of design?
Dr. Behe proposed an experiment that would demonstrate that a population of bacterium without flagelum could "evolve" into a population with. However it is very telling that the evolutionists are avoiding the experiment like it was the bird flu.

scientists studies on years earth's being are still dreaming in myths!
They have gone on from theory to theory on how earth and living creation came to being. And now they have came up with string theory and such and still hanging on with that "Bang Theory". This is called no faith and this is why they send up space vehicles to try to out-rule that there is a God and shun guilt trips as part of evil that the 1st set of people created. A baby comes into this world as 'precious' soon they have parents ruled by their whims; not all the time but many and they soon have you or others wrapped around their tiny fingers. If you let them rule they will keep it going. I have seen this happen and also those with mental and physical problems. The Word tells that we have it built into us from the time we are consceived. The world will be destroyed as it is stated in the Bible; but not until His people are taken out as well as the dead in Christ. The scientist will give their theory on that like-wise instead of the Real Book that has been around for centuries, The Bible. Yes the sky is falling, the ground is quivvering, the earth's nature is unbalanced, people have over populated and is destroying God's properties for greed and it isn't all the rich people either. I wish the times were in the days of 1700-1800, then lets see if people will buy all the garbage that is being bought today, that is cheap made just to please the eyes. I am always looking up waiting for the things to fall from the sky from the orbit that man placed up there. They will collide. they say that the right combination will take place one day, can you imagine you might type something to inquire about and wow; outer limits just happened or alfred hitchcock thriller. beam me up,huh!!

ID is most often and wrongly linked to God and creationism, as opposed to Darwinism and evolutionism. We are there in fact facing an old philosophical problem transposed this time from man to the universe: the difficult and even impossible distinction between what is innate and what is acquired. But the reader of my pages http://controlled-hominization.com/ will perhaps agree that evolutionism is not in contradiction with all forms of ID. As a materialist, I think that the confrontation between both concepts is sterile and that a synthesis is even possible.
If any great complexity of a feature could not exclude evolutionism, science itself could not reject some forms of ID in the evolution of the universe, at least in some steps of the process. After all, man himself is already a local actor in this evolution, an actor showing little intelligence so far (global warming, life sciences …). He could however be led to play a greater and nobler part if he succeeds to survive long enough (dissemination of life in the cosmos, “terraforming” of planets, planetary and even stellar formation, artificial beings…). The development of this kind of “draft ID” could only be limited by our refusal to do so and by our ability to survive. We would be viewed as gods by our ancestors from the middle Ages, and we would also view our descendants as gods if we could return in a few hundreds or thousands years.
By his refusal to consider that intelligence could already have played a significant part in the evolution of this universe, man takes in fact for granted that he is the most advanced being. It is in fact just another way for placing himself once again in the middle of everything, as for the Earth before Galileo. This anthropocentric view is not very rational.
Within the frame of evolutionism, the concept of ID could however be applied to the future man if he manages to survive long enough to be able to play a significant part in the evolution of this solar system, in the galaxy, and why not more. And it could also apply to eventual advanced ET preceding man in this cosmic part, advanced ET who could for instance, thanks to their science, have already played a significant part, even if they were themselves born from random processes.
Without going back to a controversial God, pure intelligence born from random processes is so far too easily ignored in the evolution of this universe, and I think that this choice has more to do with faith in man’s solitude in the universe than with true science. Even if it appears later that the ID concept has yet never been used by other beings in this universe, what could prevent man from applying it in the future? As with the Big Bang, ID would certainly remain in the field of hypotheses, but science progresses that way, and it would not be scientific to exclude one hypothesis that could be quite credible. ID is too easily discarded and laughed at, somewhat like continental drift not long ago, and a lot of other concepts too.
