Separating this from the Boston Marathon bombing thread
Is invoking Darwin's name, or some supposed similarity between Darwin and Dembski, supposed to be meaningful?
There is an entire field of evolutionary design and programming that contradicts this. You set up a few conditions that determine success and some basic starting point. You repeatedly generate a couple of thousand designs with small, random changes (random variation) and then pick out the ones the best fit the criteria (natural selection). You keep repeating this until you get the behavior you want. Among other things, I recall there was an antenna designed by this process, one that looked nothing like any previous antenna designed by humans, that worked better than a human-designed antenna.
By the way, tumors are also very sophisticated forms of life. Some have existed for generations, being passed on from animal to animal (or in the case of Hela cultures, Petri dish to Petri dish)
So would I. However, the reason is that, unlike the Man in the Mountain, Mt. Rushmore exhibits simplicity in it's design. Its faces are smooth, its lines are straight, its curves are steady. That's why it looks designed. That's why Complex Specified Information is an unworkable concept -- specifications are simplifications, thematically opposed to complexity.
Mt. Rushmore has no dangling parts, jury-rigged systems, useless baggage, etc. (By contrast, the man in the Mountain does have many extraneous features). Our biological systems show all kinds of complexities, but that puts them in opposition to Mt. Rushmore.
No, there are better arguments to make in this particular case.
I take it you are responding to my point that, when you join the two copies of a book together end-to-end, the result has more information than the original book. To be clear, I agree that there is no more information in the second half of the book than in the first half. It is also true that the joining of the two copies together has more information than either half does, often significantly more.
Why do you think the lack of a final step, or truly distinct steps, makes the theory untestable?
First, I'm going to replace "CSI" with "useful information". Second, this is a reductionist fallacy. You can produce something by a sequences of steps even when no one step is responsible for producing the result. One example is the division algorithm (aka long division). Subtraction is not division, and multiplication is not division, comparing the size of two numbers is not division, but by using subtractions, multiplications, and comparison in the right order, you perform division. Similarly, by combining chance and necessity, you produce useful information, even though no individual step produces it.
I think you mean "dependent", not "independent". I agree, they are dependent. Yet, the two copies laid end-to-end still has more information.
You don't think it looked like a man? Or do yo think that it was sculpted by human?
The most common languages and alphabets were not designed. They evolved. Today we design languages that imitate the products of evolution.
There is no million-year leap, just evidence of millions of years. However, By the way, do you know you are invoking super-evolution? No evolutionist would accept the huge changes in the structure of humans had occurred in hundreds or thousands of years; that would be much too fast a time for evolution to operate to that degree on a species that had a generation every fifteen/twenty years. You downplay what evolution can do, and then invoke a much stronger version of it.
Saying humans are "ape-like" is like saying house cats are "feline-like" and dogs are "canine-like". House cats are felines, dogs are canines, humans are apes. There is no evolutionary "ape-like ancestor", there is a common ancestry between humans and other apes, closer than the ancestry between any human and any non-ape, an ape ancestry.
I ain't claiming he is strictly a professional mathmetician. He has had varied professions, and it is simply one of his many professional pursuits
He happens to write in book form (20x), like Chuck Darwin. But let's move on.
Is invoking Darwin's name, or some supposed similarity between Darwin and Dembski, supposed to be meaningful?
I understand now that Dembski doesn't rule out natural, undirected contingencies (chance) altogether, but he shows how it is unable to account for the creation of coordinated, and complex systems that make up humans, other animals, and plant life.
Undirected contingencies don't account for much of anything...maybe tumors.

Dembski has no desire to deny that rocks can be eroded to look like a face, but then again if you claim the faces on Mount Mushmore are merely a product of erosion, it is then he will have a problem with your claim.

The problem for Darwiniacs is that most, if not all, of our biological systems look like "Mount Rushmore."
Mt. Rushmore has no dangling parts, jury-rigged systems, useless baggage, etc. (By contrast, the man in the Mountain does have many extraneous features). Our biological systems show all kinds of complexities, but that puts them in opposition to Mt. Rushmore.
This is where the Darwiniac quip, "God of the gaps," comes in. Except in this case the so called "gaps" are grand-canyonesque.
No, there are better arguments to make in this particular case.
Formula (*) asserts that the information in both A and B jointly is the information in A plus the information in B that is not in A. Its point, therefore, is to spell out how much additional information B contributes to A. As such, this formula places tight constraints on the generation of new information. Does, for instance, a computer program, call it A, by outputting some data, call the data B, generate new information? Computer programs are fully deterministic, and so B is fully determined by A. It follows that P(B|A) = 1, and thus I(B|A) = 0 (the logarithm of 1 is always 0). From Formula (*) it therefore follows that I(A&B) = I(A), and therefore that the amount of information in A and B jointly is no more than the amount of information in A by itself.
Dembski's formula accounts for A & B when the two are "probablistically independent" so your book could be divided into the 1st half and the second half. There is no more information in the second half than in the first half.

To be clear, I agree that there is no more information in the second half of the book than in the first half. It is also true that the joining of the two copies together has more information than either half does, often significantly more.
If that is the case then you've got yourself a crazy *** piece of dogma rather than a scientifically testable theory, which has been my point all along.
Why do you think the lack of a final step, or truly distinct steps, makes the theory untestable?
Okay, I read more thoroughly and found where Dembski addresses chance (random mutation) paired with necessity (natural selection):
Because information presupposes contingency, necessity is by definition incapable of producing information, much less complex specified information. For there to be information there must be a multiplicity of live possibilities, one of which is actualized, and the rest of which are excluded. This is contingency.
Whenever chance and necessity work together, the respective contributions of chance and necessity can be arranged sequentially. But by arranging the respective contributions of chance and necessity sequentially, it becomes clear that at no point in the sequence is CSI generated.
First, I'm going to replace "CSI" with "useful information". Second, this is a reductionist fallacy. You can produce something by a sequences of steps even when no one step is responsible for producing the result. One example is the division algorithm (aka long division).

Similarly, by combining chance and necessity, you produce useful information, even though no individual step produces it.
As I mentioned above the book could be divided into 2 halves as they would be "probablistically independent" in that way.
I think you mean "dependent", not "independent". I agree, they are dependent. Yet, the two copies laid end-to-end still has more information.
If that useless pile of rocks that collapsed 10 years ago was capable of disagreeing with me I could see it's significance.

PearlWatson: I haven't read your new responses yet but I just realized that I am either being punked or you just unwittingly provided the perfect example of Complex Specified Information with intelligent causes (language) ...
Dembski uses language as an example himself so I understand it perfectly.
Intelligent causes act by making a choice. How then do we recognize that an intelligent cause has made a choice? A bottle of ink spills accidentally onto a sheet of paper; someone takes a fountain pen and writes a message on a sheet of paper. In both instances ink is applied to paper. In both instances one among an almost infinite set of possibilities is realized. In both instances a contingency is actualized and others are ruled out. Yet in one instance we infer design, in the other chance.
The most common languages and alphabets were not designed. They evolved. Today we design languages that imitate the products of evolution.
Human teeth have different wear patterns based on human adaption. The appendix "would have" changed if development occurred over millions of years, but the changes can already be accounted for over the span of hundreds or thousands of years, so there is no need to make huge million year leaps.

If humans are "ape-like" now then the Darwiniac "ape-like ancestor" is an even more meaningless concept.
Saying humans are "ape-like" is like saying house cats are "feline-like" and dogs are "canine-like". House cats are felines, dogs are canines, humans are apes. There is no evolutionary "ape-like ancestor", there is a common ancestry between humans and other apes, closer than the ancestry between any human and any non-ape, an ape ancestry.
