Did God create life? Or did life arise via naturalistic processes, along the lines of random mutation and natural selection as suggested by Darwin? Intelligent design proponents attempt to use William Dembski’s design inference to argue that the existence of intelligent life is due to design. I will argue that the design inference is flawed, because it does not take into account the fact that the universe is spatially infinite.

In his keynote address at a recent Intelligent Design (ID) conference at Biola University, ID leader William Dembski began by quoting "a well-known ID sympathizer" whom he had asked to assess the current state of the ID movement. Dembski explained that he had asked because, "after some initial enthusiasm on his part three years ago, his interest seemed to have flagged" (Dembski 2002). The sympathizer replied that..

William Dembski holds that "the origin of information is best sought in intelligent causes" ("Intelligent Design as a Theory of Information", 1997). In particular, Dembski argues that Darwinism is not able to explain the existence of biological structures that contain a certain kind of information – "complex specified information" (CSI). To explain these informational features of living systems, we must instead appeal to the choices made by an intelligent designer.

Intelligent design theorist William Dembski has proposed an ``explanatory filter'' for distinguishing between events due to chance,lawful regularity or design. We show that if Dembski's filter were adopted as a scientific heuristic, some classical developments in science would not be rational, and that Dembski's assertion that the filter reliably identifies rarefied design requires ignoring the state of background knowledge. If background information changes even slightly, the filter's conclusion will vary wildly. Dembski fails to overcome Hume's objections to arguments from design.

Talk delivered at CSICOP's Fourth World Skeptics Conference in Burbank, California, 21 June 2002, at a discussion titled "Evolution and Intelligent Design." The participants included ID proponents William Dembski and Paul Nelson as well as evolutionists Wesley Elsberry and Kenneth Miller. Massimo Pigliucci moderated the discussion.

Intelligent design advocate William Dembski has introduced a measure of information called “complex specified information”, or CSI. He claims that CSI is a reliable marker of design by intelligent agents. He puts forth a “Law of Conservation of Information” which states that chance and natural laws are incapable of generating CSI. In particular, CSI cannot be generated by evolutionary computation. Dembski asserts that CSI is present in intelligent causes and in the flagellum of Escherichia coli , and concludes that neither have natural explanations. In this paper, we examine Dembski’s claims, point out significant errors in his reasoning, and conclude that there is no reason to accept his assertions.

I was recently on an NPR program with skeptic Michael Shermer and paleontologist Donald Prothero to discuss intelligent design. As the discussion unfolded, it became clear that they were using the phrase "intelligent design" in a way quite different from how the emerging intelligent design community is using it.

Darwin's greatest accomplishment was to show how life might be explained as the result of natural selection. But does Darwin's theory mean that life was unintended? William A. Dembski argues that it does not. In this book Dembski extends his theory of intelligent design. Building on his earlier work in The Design Inference (Cambridge, 1998), he defends that life must be the product of intelligent design. Critics of Dembski's work have argued that evolutionary algorithms show that life can be explained apart from intelligence. But by employing powerful recent results from the No Free Lunch Theory, Dembski addresses and decisively refutes such claims. As the leading proponent of intelligent design, Dembski reveals a designer capable of originating the complexity and specificity found throughout the cosmos. Scientists and theologians alike will find this book of interest as it brings the question of creation firmly into the realm of scientific debate.

Anyone new to the debate over intelligent design encounters many conflicting claims about whether it is science. A Washington Post front page story (Slevin 2005) asserts that intelligent design is “not science [but] politics.” In that same story, Barry Lynn, the director of Americans United for Separation of Church and State, claims that intelligent design is merely “a veneer over a certain theological message,” thus identifying intelligent design not with science but with religion. In a related vein, University of Copenhagen philosopher Jakob Wolf (2004) argues that intelligent design is not science but philosophy (albeit a philosophy useful for understanding science). And finally, proponents of intelligent design argue that it is indeed science (e.g., Dembski 2002a, ch. 6). Who is right?

Wisdom -- because he understands that ideas are best taught not by giving them a monopoly (which is how evolutionary theory is currently presented in all high school biology textbooks) but by being played off against well-supported competing ideas.
