Intelligent design begins with a seemingly innocuous question: Can objects, even if nothing is known about how they arose, exhibit features that reliably signal the action of an intelligent cause? To see what’s at stake, consider Mount Rushmore. The evidence for Mount Rushmore’s design is direct—eyewitnesses saw the sculptor Gutzon Borglum spend the better part of his life designing and building this structure. But what if there were no direct evidence for Mount Rushmore’s design? What if humans went extinct and aliens, visiting the earth, discovered Mount Rushmore in substantially the same condition as it is now?

There are good and bad reasons to be skeptical of intelligent design. Perhaps the best reason is that intelligent design has yet to establish itself as a thriving scientific research program. Thus far philosophical, theoretical, and foundational concerns have tended to predominate. From the vantage of design advocates, this simply reflects the earliness of the hour and the need to clear the decks before a shift of paradigms can take place. Give us more time, and we'll deliver on the program. That's our promise. Skeptics are at this point in their rights to refuse such promissory notes, albeit without sabotaging our efforts to make good on this promise.

In the case of Kitzmiller et al. v. Dover Area School District, et al., Judge Jones ruled that a pro-intelligent design disclaimer cannot be read to public school students. In his decision, he gave demarcation criteria for what counts as science, ruling that intelligent design fails these criteria. I argue that these criteria are flawed, with most of my focus on the criterion of methodological naturalism. The way to refute intelligent design is not by declaring it unscientific, but by showing that the empirical evidence for design is not there.

Proponents of intelligent design have been remarkably successful, at least in the United States, in creating a cultural movement. They have also been remarkably successful at exasperating a scientific and intellectual world that dismisses intelligent design as the latest incarnation of creationism—more sophisticated than previous incarnations to be sure, but with many of the old faults. In this paper I want to focus on intelligent design’s merits as an intellectual project. I will show that the questions it raises are legitimate and cannot be dismissed on a priori grounds. Having demonstrated that intelligent design constitutes a valid intellectual project, I want next to review intelligent design’s progress to date. Finally, I will indicate certain milestones that intelligent design needs to achieve before it can expect broad recognition from the scientific community that it is making a fruitful contribution to our understanding of the natural world.

Intelligent Design creationism is often criticized for failing to be science because it falls afoul of some demarcation criterion between science and non-science. This paper argues that this objection to Intelligent Design is misplaced because it assumes that a consistent non-theological characterization of Intelligent Design is possible. In contrast, it argues that, if Intelligent Design is taken to be non-theological doctrine, it is not intelligible. Consequently, a demarcation criterion cannot be used to judge its status. This position has the added advantage of providing reasons to reject Intelligent Design creationism without invoking potentially philosophically controversial demarcation criteria.

Intelligent design is the science that studies how to detect intelligence. Recall astronomer Carl Sagan’s novel Contact about the search for extraterrestrial intelligence (or SETI). Sagan based the SETI researchers’ methods of design detection on scientific practice. Real-life SETI researchers have thus far failed to detect designed signals from distant space. But if they encountered such a signal, as the astronomers in Sagan’s novel did, they too would infer design. Intelligent design research currently focuses on developing reliable methods of design detection and then applying these methods, especially to biological systems.

In his recent anthology, Intelligent Design Creationism and Its Critics, Robert Pennock continues his attack on what he considers to be the pseudoscience of Intelligent Design Theory. In this critical review, I discuss the main issues in the debate. Although the rhetoric is often heavy and the articles are intentionally stacked against Intelligent Design, there are many interesting topics in the philosophy of science to be found. I conclude that, contra Pennock, there is nothing intrinsically unscientific about Intelligent Design. At this stage, however, it remains more of a provocative idea than a research program. Whether design theorists can bridge this gap is still very much in question. In any case, the debate serves as a modern case study for such classic problems as the nature of scientific explanations, theory change, the demarcation problem, and the role of metaphysical assumptions in the development of science.

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.

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?
