Charles Darwin published his great work, The Origin Of Species, in 1859, and still people are writing posts like this one:
Finally, a skeptic has come to terms with reality. Douglas Kern at Tech Central Station has just posted an article on why Intelligent Design will replace neo-Darwinism as the dominant worldview on biological origins.The debate from the science side can get a bit strident at times, it is true, but that is largely because the side of nonsense has been putting forth the same arguments since (and indeed before) Darwin's day. One can understand the irritation of the practicing biologists and geologists that 80 years after the Scopes Monkey Trial, the Creationists can put the same arguments out yet again under a new name, and try to force their nonsense back into schools.Most people don't understand the ID debate, because atheist fundamentalist fruitbat critics are too busy trying to shout down any debate with vitriol - attacking the messenger instead of the message.
You've seen it in the blogosphere - the endless rants about how ID is just a 'front' for Creationism (as if Darwinism wasn't a convenient front for secular humanism) without any reasoned attempt to actually meet ID's scientific challenges head on.
And I'll ignore for now the irony of
[A]theist fundamentalist fruitbat critics ... trying to shout down any debate with vitriol - attacking the messenger instead of the message.As I wrote in comment to the above post:
A scientific theory must be predictive - you must be able to use it to make predictions (whether these are positive or negative). It must be explicative - it must explain some natural phenomenon. It must be falsifiable - there must be some experiment or observation (and one that is actually possible to perform) that can prove that it is incorrect.
Evolutionary Theory fulfils all of these requirements. That doesn't necessarily mean that it is right. (It is right, of course, but it is the never-ending avalanche of confirming evidence that tells us this.) What it means is that it is a valid scientific theory.
Intelligent Design doesn't even begin to fulfil any of these requirements. That means it is not science. It's as simple as that; it's not science. That doesn't mean that it's necessarily wrong, just that it's a load of supernatural claptrap. It could in fact be correct, and it would still be a load of supernatural claptrap.
ID is not science, by the very definition of what science is. So teaching ID in the science classroom is fraud.
And it's nonsense. It says nothing, does nothing, makes no claims, except that "Evolution is wrong". Evolution can be shown to be wrong, but the IDists (and their predecessors the Creation Scientists and their predecessors the Creationists) can't do this because there is no evidence whatsoever that Evolution is wrong. And absolute mountains of evidence that Evolution is correct.
You might as well teach homeopathy in medical school, phlogiston in chemistry and the flat-earth theory in geography. In fact, all of these are more worthwhile than ID because they can - and have - been proven false.
ID can never be proven false, and that is why it is totally worthless. You can never know if it is true or false. The whole point of science is about exactly that, of winnowing the seeds of truth from the chaff of nonsense. With ID, you simply cannot do that:
By contrast, Darwinism cannot accept even the slightest possibility that it has failed to explain any significant dimension of evolution.That's exactly the point. Evolutionary Theory must explain (or at the least, be compatible with) every significant dimension of evolution, or it is wrong. There's no point of having a theory if it doesn't explain its subject matter, and there's no point in having a theory if you can't know whether it is right or not.
Go ahead and teach ID as religion or philosophy, but it is not science, nor can it ever be.

ID arguments, in fact, all have the form of a thought experiment: a biological system is exhibited, then the expected time required for that system to be reached by random mutations is calculated, and it proves to be longer than the known lifetime of the Earth -- from which, if the calculations are right, it follows that the mutations leading to that system weren't random. The trouble is that the calculations aren't right; but as with Einstein's thought experiments, the errors in ID arguments are not simple, or scientifically uninteresting. Michael Behe's argument, for example, would be very much worth teaching, and refuting, in a high school science class.
I strongly suspect, however, that you, Pixy, aren't thinking of the arguments when you call ID "unscientific". You mean, rather, the conclusion: if ID is correct the material world cannot be wholly and correctly understood as an independent thing, yet "science" must so understand it. Therefore ID cannot be "science", even if it happens to be true; and this is your chief reason why it is almost certainly not true. The only possible remark to this is, that it is not by any stretch a refutation of ID. It is nothing more than a restatement of your personal faith in materialism.
The proper response to ID is not dismissing it as "unscientific", but giving it the same critical hearing as its proponents give to evolution.

No, I haven't discussed this with you before. If I had, you would have known what Michael Behe's argument is, since the core of his argument is a situation in which natural selection is not supposed to occur, by standard evolutionary logic.
The biological systems in question are composed of several distinct proteins (encoded in different genes) such that, if any one of them is removed, the whole system fails. Natural selection will act to preserve such systems once they exist; but natural selection cannot generate such systems. (Indeed, natural selection never generates any gene; that's what mutation is for.) So Behe's argument is, natural selection won't preserve the components of these systems independently -- each component, separated from the rest, is a neutral gene. And the odds that several neutral mutations will all occur within a single population, and be propagated into one organism, thus completing the system, are extremely low; low enough that the expected time for the happy event can easily exceed the lifetime of the Earth.
Now I've already said there's an error in this argument. But it's not failing to take natural selection into account. Standard evolutionary theory states that the incidence of neutral mutations within a population fluctuates at random, and the ages of species are estimated with the help of this rule. I leave finding the error as a exercise, for the moment ...

Wrong. The Christian assumption, that the cosmos is the creation of a rational God, entails that the cosmos is intelligible, that study of the cosmos by rational beings is not futile. Materialism doesn't entail this: for a materialist, there is no reason to expect the cosmos to be intelligible. A materialist who knew nothing of scientific enquiry would, I believe, never invent it. (And the historical record supports this: the founders of science were theists, not materialists.)
Have you ever read Eugene Wigner's essay "The Unreasonable Effectiveness of Mathematics in the Natural Sciences"? There, Wigner makes it clear just how surprising it is that the cosmos is intelligible.

Behe's argument makes no use of the idea that "evolution is supposed to work backwards". Try again, please.
All that materialism tells us is that all material events have material causes. And that is both necessary and sufficient to build science.
Would you agree that David Hume was a materialist? Because he is famous for denying the validity of science: "when we look about us towards external objects, and consider the operation of causes, we are never able, in a single instance, to discover any power or necessary connexion; any quality; which binds the effect to the cause, and renders the one an infallible consequence of the other. We only find, that the one does actually, in fact, follow the other ..."

No. Behe did not say that, nor did I. I'll repeat: Behe's argument is, natural selection won't preserve the components of these systems independently -- each component, separated from the rest, is a neutral gene. And the odds that several neutral mutations will all occur within a single population, and be propagated into one organism, thus completing the system, are extremely low; low enough that the expected time for the happy event can easily exceed the lifetime of the Earth.
More concretely, suppose a system of 4 enzymes ABCD, for which any subset does nothing -- ABC, ABD, ACD, and BCD are all useless. Once any organism has ABCD, natural selection favors that organism over other members of its population, and the system becomes common. But (according to Behe) A, B, C, and D, separately, give no advantage to an organism; therefore natural selection does not affect their frequency in a population. So the probability that any one organism will end up with ABCD, all at once, is extremely low.
I trust you see now why the suggestion that ABCD is simplified from a larger system, say ABCDE, doesn't help matters. A system of 5 components is even less likely than one of 4. Even supposing that E is a substitute for D leaves the system's likelihood at the same order of magnitude; ABCE is no more probable than ABCD.
I give no thought to David Hume whatsoever. And having read that quote, I can only point out that it is entirely irrelevant to science. In fact, I'm not at all convinced that it is actually meaningful. The only way you can connect a cause to an effect is via an intermediate cause. What does Hume expect to find? Magic fairies?
Actually, Hume was saying that the ordinary concept of causation is an appeal to magic fairies, and that there is no real connection from a cause to its effect. Scientific theories, on Hume's account, are merely summaries of patterns we find in history. We ascribe predictive power to them only because we assume, prior to all observation, a "law of uniformity". This assumption cannot be rationally justified, but everyone believes it because it works well in practice.
You see, I hope, that denying the reality of causal links is going to affect scientific enquiry if the enquirers can be induced to believe it?
