Of course, sometimes I get the impression that Art might consider anyone who doesn't accept Darwinian theory as a nut case and a charlatan, but I'm perfectly willing to take that back if he has more specific criteria (which he's welcome to mention here).
Here is the press copy on the man in question:
Scott's chief witness will be the real-life Dr. Ben Scripture, who received his Ph.D. in biochemistry from the University of Notre Dame in1998. Dr. Scripture has earned degrees from the University of California at Berkeley (a A.B. in zoology) and Grace Theological Seminary (M.Div.). Dr. Scripture has published articles in the Journal of Biological Chemistry and the Journal of Molecular Biology. He hosts weekly radio programs, "Scripture on Creation" and "That's What Scripture Says" on radio stations in Fort Wayne, Ind., and Indianapolis, and on the Good News Network stations covering the southeastern region of the U.S.On the one hand, he's apparently credentialed, but on the other, he is apparently at the far right end of the spectrum on the issue, believing in a literal six-day creation. I don't happen to share that view, but I also don't think someone is a nut case for believing it.
It would be interesting to know what person Art considers to be the least nutty non-charlatan representative of the creationist side.
But Art's main point has to do with the question of whether the creationist side will be adequately represented. I have been around long enough to know that when such "debates" take place under the auspices of institutions that are hostile to those views, often the worst representatives are chosen to give the unpopular view. Art is right about that. If you doubt it, just go back and watch PBS's "Judgment Day".
Whether this is one of those cases remains to be seen I suppose. But, as I mention on the other post, there are two questions here: the first is the question of free and open discussion if important issues, and the second is the question of whether that discussion is done in a fair and representative way.
We already know where the pro-evolution side is on the question of free and open discussion in our educational institutions: they're against it. Whether the institution now promoting the free and open discussion does it fairly is something we'll have to see about.
