Is Intelligent Design A Duplicitous Ruse?

Is intelligent design a duplicitous ruse to get religion into science and schools as Jerry Coyne believes?
“Far from a respectable scientific alternative to evolution, it is a clever attempt to sneak religion, cloaked in the guise of science, into the public schools.” -- Jerry Coyne, here.
Not according to William Dembski:
Intelligent design is a modest position theologically and philosophically. It attributes the complexity and diversity of life to intelligence, but does not identify that intelligence with the God of any religious faith or philosophical system....
Even so, there is an immediate payoff to intelligent design: it destroys the atheistic legacy of Darwinian evolution. Intelligent design makes it impossible to be an intellectually fulfilled atheist. This gives intelligent design incredible traction as a tool for apologetics, opening up the God-question to individuals who think that science has buried God." -- William Dembski, 2005, here.
Intelligent design asserts design but stops short of speculating about the nature or identity of the intelligent designer. It does so because it is a scientific construct. It is a disciplined theory which stops where the empirical evidence ends.

Unlike darwinism, which endlessly asserts there can be no God because God "would not have designed it this way":
Would an intelligent designer create millions of species and then make them go extinct, only to replace them with other species, repeating this process over and over again?” If so, the intelligent designer must be “a cosmic prankster".  -- Jerry Coyne, here.
This philosophical/theological strain began with Darwin, and continues to the present day.

However, going beyond the science, philosophically and theologically there is little common sense doubt whose imprint marks of design in nature would point to, as Dembski acknowledges in his second paragraph.

So, is ID duplicitous?

No. It is honest and disciplined in what it asserts.

It's unclear the same can be said about darwinism.

Does Intelligent Designer = Intelligent Intervenor?

Michael Behe, professor of biochemistry at Leh...              Image via Wikipedia
 “Those who worry about ‘interference’ should relax. The purposeful design of life to any degree is easily compatible with the idea that, after its initiation, the universe unfolded exclusively by the intended playing out of the natural laws.” (Behe, Edge of Evolution 232)
Last week I was hammered at an Intelligent Design-friendly Christian apologetics site for suggesting that information, language, and design complexity in nature point to intelligent agency, but they do not necessarily require that an agent actively intervened in natural processes at point(s) in time. I suggested that while natural processes as viewed by materialists and atheists could not account for life and species, natural processes created and sustained by an intelligent agent (especially an omnipotent creator, since I was arguing theologically at a Christian site) at least in principle could.

It was not a kick against direct agency, it was just leaving the door open to another possibility. (And it was securing a place for ID even if plausible law-based natural processes should be discovered that would adequately explain anomalies such as the origin of life or the Cambrian explosion.) I certainly didn't deny the possibility or even likelihood of direct agency.

But that didn't matter. I had offended the site's ID orthodoxy and the site went into attack-mode. I was accused of intellectual dishonesty. I was accused of disbelieving in miracles. It was demanded of me that I provide peer-reviewed science articles to back my claims (which was interesting because a sub-point I was making was the epistemological limits of science). Finally, I was flat-out accused of misrepresenting the claims of ID. One guy said I was flat-out wrong and he wasn't interested in anything further I had to say. So, there was a lot of heat. And the site administrator heartily endorsed this guy's comments.

I figure when the ref is in the other guy's corner, it's probably time to get out of the ring. So, I exited, stage right (to metaphor my mixes).

Because I had been pummelled, yet still thinking my point was well-reasoned, I started digging.  What I found was gratifying: the leading proponents of ID agree with me.

The first hint of this came during my debate at the ID-friendly site. I ran across this in a blogpost at Uncommon Descent entitled "Does ID presuppose a mechanistic view of nature?"
Michael Behe, Michael Denton and Bill Dembski are all on record as saying that design is not in principle incompatible with a wholly naturalistic evolutionary process. Design theory does not require miracles. One can imagine, for example, a “front-loaded” evolutionary program which over time “outputs” the various species via wholly naturalistic means. But such a program would be intelligently designed, not driven by chance. Darwin, Dawkins, Dennett, etc. would still therefore be wrong. It is not “naturalistic means” per se that ID is against; it is naturalistic means conceived of in terms of blind natural laws combined with sheer chance. On this point, I would suggest that you read carefully Michael Denton’s work, *Nature’s Destiny*, which shows how one can logically combine naturalistic evolution, anti-Darwinism, and intelligent design. 
Next, I discovered an article by Bill Dembski which I hi-lited last week.
Intelligent design is not... an interventionist theory at all. Indeed, intelligent design is perfectly compatible with all the design in the world being front-loaded in the sense that all design was introduced at the beginning (say at the Big Bang) and then came to expression subsequently over the course of natural history much as a computer program's output becomes evident only when the program is run. 
Then, today, while listening to Michael Behe's The Edge of Evolution I came across the money-quote shown at the top of this post. Intelligent design theory is compatible with the view that all of life was created by natural laws.  If you read it carefully Behe doesn't say he endorses this view, but that it is a live option; it's on the table.

What both Dembski and Behe say is that while the evidences of intelligent design do not (necessarily) require active intervention by an intelligent agent, they do require that we reject the materialistic, dumb-luck view of nature espoused by darwinism.

Which was the point I was making.

And that's the way the Ball bounces.

Update: This quote is relevant:

"A theory of design detection is quite different from a theory of design implementation."

ID is primarily a theory of design detection rather than design implementation.

Does Intelligent Design Require An Interventionist View?

Picture of William Albert Dembski taken at lec...                                Image via Wikipedia
A common assumption among both defenders and detractors of Intelligent Design (ID) is that the hypothesis demands an interventionist view of the designer. While I think given the evidence associated with origins of life and biological evolution (e.g., the Cambrian explosion)  that this is in fact most likely the case, I also believe that it is not essential to the hypothesis. It simply needs to show that there are clear marks of intelligent agency in the outcomes achieved. I recently discovered to my chagrin how some defenders of ID react with belligerence when a more nuanced point of view is presented crossed on this issue.

So, I went and did a bit of digging.  And struck gold. With this 2003 article by William Dembski, a leading spokesman in the ID movement. The relevant section is section 2, Interventionism, beginning on page three. I can't copy/paste/quote directly because this is a pdf file, but with a bit more digging I found a similar passage online:
For a designing intelligence to make a discernible difference in the emergence of some organism, however, seems to Miller to require that an intelligence intervened at specific times and places to bring about that organism and thus again seems to require some form of special creation. This in turn raises the question: How often and at what places did a designing intelligence intervene in the course of natural history to produce those biological structures that are beyond the power of material mechanisms? Thus, according to Miller, intelligent design draws an unreasonable distinction between material mechanisms and designing intelligences, claiming that material mechanisms are fine most of the time but then on rare (or perhaps not so rare) occasions a designing intelligence is required to get over some hump that material mechanisms can't quite manage. Hence Miller's reference to "an outside designer violat[ing] the very laws of nature he had fashioned."
As I've pointed out to Miller on more than one occasion, this criticism is misconceived. The proper question is not how often or at what places a designing intelligence intervenes but rather at what points do signs of intelligence first become evident. Intelligent design therefore makes an epistemological rather than ontological point. To understand the difference, imagine a computer program that outputs alphanumeric characters on a computer screen. The program runs for a long time and throughout that time outputs what look like random characters. Then abruptly the output changes and the program outputs the most sublime poetry. Now, at what point did a designing intelligence intervene in the output of the program? Clearly, this question misses the mark because the program is deterministic and simply outputs whatever the program dictates.
There was no intervention at all that changed the output of the program from random gibberish to sublime poetry. And yet, the point at which the program starts to output sublime poetry is the point at which we realize that the output is designed and not random. Moreover, it is at that point that we realize that the program itself is designed. But when and where was design introduced into the program? Although this is an interesting question, it is ultimately irrelevant to the more fundamental question whether there was design in the program and its output in the first place. We can tell whether there was design (this is ID's epistemological point) without introducing any doctrine of intervention (ID refuses to speculate about the ontology of design)
Intelligent design is not a theory about the frequency or locality at which a designing intelligence intervenes in the material world. It is not an interventionist theory at all. Indeed, intelligent design is perfectly compatible with all the design in the world being front-loaded in the sense that all design was introduced at the beginning (say at the Big Bang) and then came to expression subsequently over the course of natural history much as a computer program's output becomes evident only when the program is run. This actually is an old idea, and one that Charles Babbage, the inventor of the digital computer, explored in the 1830s in his Ninth Bridgewater Treatise (thus predating Darwin's Origin of Species by twenty years).
This is similar to an idea that I was expressing. I used the example of a signature on a document. Does a signature indicate a signator, an intelligent agent. Yes. Does it "prove" that the signator signed the document at the moment it appeared on the document? No, it does not. The signator may have designed a signature-writing machine and programmed the machine to write the signature under certain conditions. Can we tell if the signature was directly signed, or signed by the machine? Maybe. Either way, a signature is evidence of an intelligent agent.

Dembski then goes on to raise another point I had made -- that what is really at stake is the materialistic-mechanical view of the universe assumed by darwinism.
Let's be clear, however, that such preprogrammed evolution would be very different from evolution as it is now conceived. Evolution, as currently presented in biology textbooks, is blind -- nonpurposive material mechanisms run the show. Within this naturalistic conception of evolution, the origin of any species gives no evidence of actual design because mindless material mechanisms do all the work. Within a preprogrammed conception of evolution, by contrast, the origin of some species and biological structures would give evidence of actual design and demonstrate the inadequacy of material mechanisms to do such design work. Thus naturalistic evolution and preprogrammed evolution would have different empirical content and be distinct scientific theories.
The terms naturalistic vs. preprogrammed evolution are perhaps imprecise. It depends on one's view of nature. But this was 2003. He may have evolved since then.

Having established his point, he then rounds things out to show the broader picture:
Of course, such preprogrammed evolution or front-loaded design is not the only option for the theory of intelligent design. Intelligent design is also compatible with discrete interventions at intermittent times and diverse places. Intelligent design is even compatible with what philosophers call an occasionalist view in which everything that occurs in the world is the intended outcome of a designing intelligence but only some of those outcomes show clear signs of being designed. In that case the distinction between natural causes and intelligent causes would concern the way we make sense of the world rather than how the world actually is (another case of epistemology and ontology diverging). 
He concludes by commenting on the epistemological limits to science.
 We may never be able to tell how often or at what places a designing intelligence intervened in the world or even whether there was any intervention in Miller's sense of violating natural laws. But that's okay. What's crucial for the theory of intelligent design is the ability to identify signs of intelligence in the world -- and in the biological world in particular -- and therewith conclude that a designing intelligence played an indispensable role in the formation of some object or the occurrence of some event. That is the start. Often in biology there will be clear times and locations where we can say that design first became evident. But whether that means a designing intelligence actually intervened at those points will require further investigation and may indeed not be answerable. As the computer analogy above indicates, the place and time at which design first becomes evident need have no connection with the place and time at which design was actually introduced.
 In the context of biological evolution, this means that design can be real and discernible in evolutionary change without requiring an explicit "design event," like a special creation, miracle, or supernatural intervention. At the same time, however, for evolutionary change to exhibit actual design would mean that material mechanisms were inadequate by themselves to produce that change. The question, then, that requires investigation is not simply what are the limits of evolutionary change, but what are the limits of evolutionary change when that change is limited to material mechanisms. This in turn requires examining the material factors within organisms and in their environments capable of effecting evolutionary change. The best evidence to date indicates that these factors are inadequate to drive full-scale macroevolution. Something else is required -- intelligence.
I found it very satisfying to find this article which mapped to my thoughts so closely. Will I be sharing it with the ID-friendly site in question? No. If I want to open myself to intemperate smack-downs characterized by a failure to even listen to and try to understand the point I am trying to make, there are lots of atheist sites I can visit.
