Mark Twain, that 19th Century freethinker, wrote in "A Connecticut Yankee in King Arthur's Court" that "every time the magic of folderol tried conclusions with the magic of science, the magic of folderol got left." Yes, the magic of folderol lost in Dover, but as the book opens, it hardly seems inevitable.
Well, Twain didn't live in 21st Century rural America. Slack's book highlights how the "Intelligent Design" movement is another battle between those who find neither meaning nor morality nor knowledge attainable except in the context of intimate relationship to the Christian Deity, and those who don't. Not all of the latter are atheists, of course, but they include all scientists who prefer not to organize the history of the natural world around 3000-year-old writings.
There are many books on the Dover trial out now. What Slack's does better than any other is peer into divisions on the anti-scientific side. The members of the Dover School Board, one of whom had completed only the eighth grade herself, are willfully ignorant. They couldn't explain or define the scientific or pseudo-scientific issues. All they saw in Intelligent Design and its pet textbook "Of Pandas and People" (entitled "Creation Science" in its original edition!) was something closer to their brain-dead reading of Genesis 1 than the traditional biology textbooks. They were also "Liars for Christ", in Slack's colorful description, swearing falsely at their depositions. (This book hints more clearly than the others that the Superintendent also lied.) But there were more sophisticated ID champions, including the author's own father. They adhere to the same need to support their faith from natural evidence: a sort of self-directed apologetics. Slack illuminates how the scientifically literate and illiterate subscribers to ID/creationism are willing to make common cause against non-theistic epistemology, but also the tensions between them.
I recommend this book for its insights into a lamentably large segment of American society. Humes' Monkey Girl: Evolution, Education, Religion, and the Battle for America's Soul is still the best of breed.
I should also point out that it has been edited just as sloppily as the other books on Dover. Friedrich Dürrenmatt was certainly not a Dutch playwright (he was Swiss), Kennedy does not have three consecutive ns, and the attempt to typeset circumflexes is somehow, even in this day of computerized publishing, bungled.
