Recent news accounts about controversies over evolution in Ohio and Georgia have contained references to the scientific theory of "intelligent design." Some advocates of Darwinian evolution try to conflate "intelligent design" (ID) with "creationism," sometimes using the term "intelligent design creationism." (1) In fact, intelligent design is quite different from "creationism," as even some of its critics have acknowledged. University of Wisconsin historian of science Ronald Numbers is critical of intelligent design, yet according to the Associated Press, he "agrees the creationist label is inaccurate when it comes to the ID movement." Why, then, do some Darwinists keep trying to identify ID with creationism? According to Numbers, it is because they think such claims are "the easiest way to discredit intelligent design." (2) In other words, the charge that intelligent design is "creationism" is a rhetorical strategy on the part of those who wish to delegitimize design theory without actually addressing the merits of its case.

I'm used to death threats. I get them five times a day at home.
What does science do when to two go opposite ways?
Can you give an example of this? I am not sure of what your trying to get at here.
DallasMike:Of course it does.
Really? Following is a schematic of something as simple as blood clotting in response to an injury. Note that each of the proteins depend upon the presence of another for activation, and several of the proteins play multiple roles (for example, thrombin is an allosteric enzyme that exists in two forms, slow and fast, that play both anticoagulant and procoagulant roles). Remember that the absence of a single component wouldn't make blood clot less effectively, it would prevent blood from clotting at all. There's the rub. If Darwinian evolution explained complex chemical systems, we would expect the body to be full of millions of compounds in the evolutionary hope that they might work together to the benefit -- not harm -- of the organism. That just isn't the case.
Schematic representation of the blood coagulation cascade showing the major interactions and regulatory feed-backs that lead to the conversion of zymogens (rectangles) to active proteases (ovals). Also shown is the fibrinolytic pathway leading to digestion of the fibrin clot. Procoagulant reactions are in green, reactions with protease inhibitors are black dotted lines and the protein C mediated anticoagulant pathway is in red. The vitamin K-dependent proteases thrombin (factor IIa), factors Xa, IXa, VIIa and activated protein C all possess a functional Na+ binding site (yellow) that is required for efficient catalysis. These proteases occupy strategic positions in the cascade and define the intersection between the intrinsic and extrinsic pathways. Na+ is a coagulation factor necessary for rapid activation of factor X by factors IXa and VIIa, leading to rapid thrombin generation from prothrombin (factor II) and efficient cleavage of fibrinogen by the fast form of thrombin.

[see Di Cera et al (1997) Cell Mol Life Sci 53:701-730; Di Cera (1998) Trends Cardiov Med 8:340-350].
As I said, evolution gives an explanation for blood clotting; it is very simple. An organism with blood that doesn't clot is disadvantaged in passing on its genes compared to an organism that does but is in other respects the same.
If you're expecting a detailed, step-by-step breakdown of the advent of the blood clotting processes in your post, that may be forthcoming as we get more understanding of the genetics. But maybe not; suppose I flip a coin 1000 times. I get 507 heads and 493 tails. Would you want a detailed explanation of why? Would it be meaningful to you?
In other words, given enough time, anything can happen. That's what Behe calls the "black box" of evolution, and we're just supposed to have faith in that "black box."
My experience is that chemists and biochemists in particular very often have huge doubts in evolution as currently preached. We specialize in the details and that is where devils often hide.
Notice that the originial blood clotting systems had to stem leaks from largely unpressurized blood vessels. Right there you have a much simpler environment that the blood clotting system has to work in. The way Doolittle built the case for the blood clotting cascade's evolution is a fascinating scientific detective story, IMO.
1. "Intelligent Design Creationism" is a pejorative term coined by some Darwinists to attack intelligent design; it is not a neutral label of the intelligent design movement.2. Unlike creationism, intelligent design is based on science, not sacred texts.
3. Creationists know that intelligent design theory is not creationism.
4. Like Darwinism, design theory may have implications for religion, but these implications are distinct from its scientific program.
5. Fair-minded critics recognize the difference between intelligent design and creationism.
Mike Dunford's post at talk.origins, which became December 2002's Post of the Month, implicitly refutes all these claims:

To my knowledge, they have not made any statements detailing why they believe their "theory" can say nothing about the nature of the designer. In general, their tactic has been to make that assertion loudly and frequently, and hope that it goes unquestioned.
Here's one example:
Within biology, intelligent design holds that a designing intelligence is indispensable for explaining the specified complexity of living systems. Nevertheless, taken strictly as a scientific theory, intelligent design refuses to speculate about the nature of this designing intelligence. Whereas optimal design demands a perfectionistic, anal-retentive designer who has to get everything just right, intelligent design fits our ordinary experience of design, which is always conditioned by the needs of a situation and therefore always falls short of some idealized global optimum. (Dembski, 2000)
Notice that while Dembski states that "intelligent design refuses to speculate about the nature of this designing intelligence", he provides no reason, no justification for this refusal. In every other science where we identify design, such "speculation" is a major, massive part of the effort. Scientists do not, for example, refuse to speculate about the nature of the "designer" when they find the ancient, well dressed remains of a dead girl preserved in an archaeological site high up an Andes Mountain. Instead, they "speculate" that she was probably sacrificed to the mountain gods of the Incan culture. (for more information on this, see http://www.mountain.org/reinhard/docs/academic/newsart.htm). If the designer that Dembski and others claim to see in biology is truly unknown, why shouldn't we use the very evidence (they claim) leads us to conclude that a designer is the cause to make conclusions regarding the nature of this "designer"? Dembski's answer is somewhat revealing.
Dembski continues:
The success of the suboptimality objection comes not from science at all, but from shifting the terms of the discussion from science to theology. In place of How specifically can an existing structure be improved? the question instead becomes What sort of God would create a structure like that?...The problem of suboptimal design is thus transformed into the problem of evil.... Critics who invoke the problem of evil against design have left science behind and entered the waters of philosophy and theology. A torture chamber replete with implements of torture is designed, and the evil of its designer does nothing to undercut the torture chamber's design. The existence of design is distinct from the morality, aesthetics, goodness, optimality, or perfection of design. Moreover, there are reliable indicators of design that work irrespective of whether design includes these additional features (cf. my previous posts to META).
Notice Dembski's tactic here. The problem of evil, he now claims, is a theological one, not a scientific one. But how does he know this? Dembski is one of the people in the ID movement who has been most vocal about claiming that "space aliens" could have been the designer, and that they are not making any assumptions about the designer (see, for example, Hall, 2002). If he is sincere about that, why would he call the question one of "philosophy or theology"? In principle, shouldn't we proceed from the identification of design in biology just as was done with the identification of design at the Incan sacrifice site I referred to above?
There is something that I should make explicitly clear at this point. Dembski's argument in the article I am quoting from is directed toward those who claim that the fact that the "design" is "evil" or "suboptimal" indicates that there is no actual design. That is not my argument here. In fact, at least to a limited extent, I agree with Dembski that the presence of "suboptimal" or "evil" design does not in and of itself argue against the presence of a designer (it does not necessarily argue for one, either, of course). My point is a bit more basic: if the advocates of "Intelligent Design" are sincere in their statements that they are not committed to any particular "designer", what possible scientific reason could there be for refusing to make inferences about the "designer" from the "designed"?
Reading the conclusion of Dembski's article, the answer becomes all too clear:
One looks at some biological structure and remarks, "Gee, that sure looks evil." Did it start out evil? Was that its function when a good and all-powerful God created it? Objects invented for good purposes are regularly co-opted and used for evil purposes. Drugs that were meant to alleviate pain become sources of addiction. Knives that were meant to cut bread become implements for killing people. Political powers that were meant to maintain law and order become the means for enslaving citizens.
This is a fallen world. The good that God initially intended is no longer fully in evidence. Much has been perverted. Dysteleology, the perversion of design in nature, is a reality. It is evident all around us. But how do we explain it? The scientific naturalist explains dysteleology by claiming that the design in nature is only apparent, that it arose through mutation and natural selection (or some other natural mechanism), and that imperfection, cruelty, and waste are fully to be expected from such mechanisms. But such mechanisms cannot explain the complex, information-rich structures in nature that signal actual and not merely apparent design--that is, intelligent design.
The design in nature is actual. More often than we would like, that design has gotten perverted. But the perversion of design--dysteleology--is not explained by denying design, but by accepting it and meeting the problem of evil head on. The problem of evil is a theological problem. To force a resolution of the problem by reducing all design to apparent design is an evasion. It avoids both the scientific challenge posed by specified complexity, and it avoids the hard work of faith, whose job is to discern God's hand in creation despite the occlusions of evil.
Clearly, Dembski does have a firm commitment to a particular designer. He is so firmly committed, in fact, that he is refusing to consider the possibility that any other possible "designer" is involved, no matter what comments he might make in public about "space aliens". Unfortunately, he is so committed to his particular designer that he misses a massive, fundamental flaw in his claim that the "problem of evil" is a theological one.
The "problem of evil" is only a theological problem if you presume a priori the presence of a benevolent, all-powerful God. In fact, it is a theological problem because it appears to argue against the existence of such a benevolent deity. If we make no presumptions about the nature of the designer, then the presence of what Dembski calls "dysteleology" is not a "problem", nor is it evidence of a "perversion of design", nor of a "fallen world". Instead, it is simply one piece of evidence which could potentially help to identify the nature and motives of the designer. The only reason not to draw inferences is if you are attempting to insulate your own particular theological beliefs from the conclusions.
If we have no preconceived conclusions about who is responsible for the "intelligent designer", what would we conclude from our observations of nature? We observe, in nature, a great deal of activity that most of us find to be distasteful, repulsive, and cruel. If we conclude that living organisms are designed, and we know that some of these organisms reproduce by laying eggs within a living organism, so that their newly-hatched young can quite literally eat the helpless creature from the inside out, how can we infer that the designer of this system is a kind and benevolent one? That is the "problem of design" -- if you look at nature without faith that it is the product of an all-powerful and kind deity, it is difficult (perhaps impossible) to conclude that it is.
So, to (finally) answer your question, I think that their refusal to "speculate" or "draw inferences" about the nature of the designer is nothing more than trickery. It is a tactic that is clearly designed to insulate their Christian beliefs from the possible consequences of what they claim is a scientific investigation of design in nature. It makes a mockery out of both their claim to have no particular designer in mind and their claim that they are simply following the scientific evidence where it leads -- especially that second one.
> Their motives aside, is their intent then only to demonstrate
> intelligent design?
That depends, I suppose, on how you make the distinction between "motives" and "intent". In front of school boards, or in the media, you do tend to find the major proponents of "Intelligent Design" claiming essentially that their intent is only to demonstrate design (see, again, Hall, 2002). Dembski, for example, usually manages to leave out the stuff about "fallen world" and "perversion of design" when he is trying to get ID taught in the public schools. So do other major proponents of ID (see, for example, Chapman & Meyer, 2002), claiming instead that this is entirely a scientific debate.
All three of the authors I just cited are associated with the Discovery Institute (DI) and/or its Center for Science and Culture (CRSC). Chapman is the president of the DI, Meyer is the director of the CRSC, and Dembski is a "Senior Fellow". The currently available statement of the public purpose of the CRSC (see http://www.discovery.org/crsc/about.html) mirrors their statements to public audiences. Both an earlier version of their "about" page, (http://web.archive.org/web/19970514072337/www.discovery.org/crsc/aboutcrsc.html) and a widely circulated internal memo, known as the "Wedge Document" (CRSC, undated) provides a somewhat different view. (See Forrest, 2001, for a discussion of the authenticity of the document.)
From the Wedge Document:
"Discovery Institute's Center for the Renewal of Science and Culture seeks nothing less than the overthrow of materialism and its cultural legacies." (An identical statement was a part of the 1997 version of their "About CRSC" page cited above.)
Is it their intent simply, as they claim, to follow the evidence where it leads (and if so, why stop short of looking at the intent of the designer), or is their "scientific" objection to evolution simply a tactic designed to aid their expressed intention of overthrowing "materialism"? Personally, I think that even a casual examination of what they have done and written seems to strongly favor the second. They say that they intend to overthrow materialism and replace it with something that is theistically based, and I see no reason to doubt them on that.
> And then would you say that they are correct or incorrect in
> their demonstration of that design being intelligent?
[snip]
I think that they are incorrect in saying that they have demonstrated that design is present. Currently, the entire "scientific" portion of their "theory" seems to rest on the work of two people -- Michael Behe (see Behe, 1996), and William Dembski (see Dembski, 2002). Numerous authors have pointed out major flaws in the work of both, in fora ranging from internet websites and discussion forums to popular and scholarly works. (for example, see Miller, 1999, for a detailed criticism of Behe's work.) This post has run long enough already, and a detailed explanation of intelligent design's flaws would take up too much more time and space to go into now. For more information on those topics, you can go to www.talkorigins.org, www.talkdesign.org, or www.antievolution.org.

For Michael Behe's take on Kenneth Miller's critiques, see his response to Kenneth Miller. Behe points out that Miller engages in bombastic, exaggerated prose (true) and that he misrepresents experiments by Barry Hall, who in the 1970s produced a strain of E. coli in which the gene for just the B-galactosidase of the lac operon was deleted. Miller neglected to mention that the strain of E. Coli was supported by the addition of IPTG to bring lactose into the cell before the adaptive mutations took place.
What part of "do not copy me on any more of your moronic posts" did you not understand? Quit your infantile harassment.
Although true (so long as physical law is not violated), that's not what I said. You asked for an evolutionary explanation and I gave one. And btw, my recollection is that Behe means the cell when referring to the "black box."
We specialize in the details and that is where devils often hide.
Sometimes details are informative and sometimes not. For example, you didn't seem every interested in a recounting of the sequence of heads and tails in my 1000 tosses. Me neither.

They have no business encouraging homosexuality, or forcing its acceptance upon students or faculty. The schools should teach the kids to behave like civilized people, that every individual should be treated with respect. Instead, they choose to indoctrinate them in leftist ideology. The entire school should be a safe zone for everyone. The whole idea of special protection for any one group is unAmerican.
