The indefatigable Michael Shermer has joined the lists of those authors bent on providing ammunition for the ongoing struggle against that old shape-shifting dragon, creationism, in its latest avatar, the "intelligent design" movement. His new book, Why Darwin Matters, gets high marks for its amiable style, its readability, and the unmistakable moral passion of the author. It is impressive in the wide range of issues and questions it addresses. Most important, it is likely to be a useful contribution to the unfinished task of providing the resistance to creationism, among both scientists and laypeople, with a repository of direct arguments, rhetorical devices, and philosophical themes useful in defeating or deflecting the spectrum of creationist assaults now directed against the educational system. On the other hand, if one is looking for a definitive volume of heavyweight analysis of theoretical questions about evolution and its place among the sciences, or about the history and sociology of American creationism, or about the interface between science and religion, Shermer's brisk little volume is not really in the running. It has flaws, gaps, and lapses, none fatal to its intended purpose, to be sure, but cumulatively serious enough so that it has to be said that a reader armed with this book alone will not be entirely prepared for a full-bore debate with a seasoned creationist, in or out of the context of fights over curricula and biology textbooks.

Among its virtues is the fact that Why Darwin Matters covers a very wide range of topics, citing a host of arguments against standard evolutionary theory from a number of strands of creationist ideology, and providing brief, accessible rejoinders — for the most part effective — to those arguments. Among its defects is the problem that this breadth, combined with the brevity of the book as a whole and its occasional digressiveness, inevitably renders some of the counterarguments sketchy and even shallow. The unpretentious informality of Shermer's style is welcome, but the downside is that some of his debating points have an improvised and off-the-cuff feel to them, and lack the depth and heft necessary to make really telling points in serious debate. They are starting points indicating the possibility of more elaborate and focused lines of argument, rather than crushing weapons in their own right.

The wide range of issues considered by the author also has the lamentable effect of diffusing the ostensible focus of the book, that is, how to counteract the ambitions of the "intelligent design" movement per se. The somewhat haphazard organization of chapters and topics has a similar effect. There are some matters that Shermer ought to have thought through seriously, from both a theoretical and expository point of view. Instead, he seems to have tried to work them out on the fly, at the cost of precision and even relevancy. In particular, the notion of what is supposed to be meant by "intelligent design" is somewhat wooly in this treatment, leading to the needless conflation of very different positions and attitudes.

What does "intelligent design" of the visible universe mean? Presumably, any religion or set of spiritual convictions that posits some kind of shaping intelligence in the cosmos and its history, some kind of entelechy, no matter how vague, providing purpose and direction for the universe, ipso facto incorporates a kind of "intelligent design theory". These belief-systems range from dogmatic, orthodox religion to non-sectarian theism, Deism, and even Spinozan pantheism. Rank atheists (like me) might not cotton to any of these ideas, but the point is that "intelligent design" in this very broad sense includes many creeds not particularly inimical to evolutionary theory or its privileged presence in biology classrooms.

But "intelligent design", as formulated and promulgated by the paladins of the Discovery Institute, is a very different matter. To keep things clear, let's refer to this as Intelligent Design™. This is a very narrow doctrine, or rather, scheme for denigrating standard evolutionary theory. The core tactic is to provide "scientific" arguments purporting to show that the quintessential Darwinian mechanism — random variation at the genetic level acted upon by various selective forces — cannot possibly account for the observed complexity and intricacy of living forms. It is conjoined with the thesis that the putative inadequacy of selection in accounting for various biological phenomena leads inexorably to the inference that a creative intelligence must be directly responsible for these phenomena. Intelligent Design™, moreover, incorporates a highly focused legal, political, and cultural strategy for making its ideals ultimately prevail in popular opinion. Its further goal, which it has been indiscreet enough to display from time to time, is to re-legitimatize the biblical creation story, rendering it immune to scientific refutation. Its ultimate goal is to remake this country and perhaps others as virtual theocracies subject to the dogmas of conservative Christianity.

Shermer finally gets around to defining and analyzing Intelligent Design™, as such, about two-thirds of the way through his book. But first, he spends quite a bit of time refuting some very different aspects of the broad notion of "intelligent design" — sometimes aptly, sometimes not. Finally, he appears to contradict himself, in that he adds a chapter on the desirability of irenic and mutually respectful relations between science and some kinds (necessarily liberal) of religious and spiritual belief. To the extent that these are teleological in character — and it is hard to think of any that are not — they encompass an "intelligent design" in the broad sense indicated above, albeit one that may be quite benign in the context of the current bloodletting over Intelligent Design™.

Shermer would have served his book and its readers better had he focused primarily on Intelligent Design™, its godfather Phillip E Johnson, and its hit squad, notably Michael Behe and William Dembski. Still, a parent or student menaced by an aggressively creationist school board would be well advised to get hold of a copy of Why Darwin Matters as a ready-to-hand source of arguments useful and pertinent enough to force the battle-lines to be accurately drawn.
