Despite this public questioning of Darwinism (and neo-Darwinism), which I reported on in Scientific American, Schopf, Roughgarden, Margulis and Provine have not been persecuted, shunned, fired or even Expelled. Why? Because they are doing science, not religion. It is perfectly okay to question Darwinism (or any other "-ism" in science), as long as there is a way to test your challenge. Intelligent design creationists, by contrast, have no interest in doing science at all. In the words of mathematician and philosopher William Dembski of Southwestern Baptist Theological Seminary and a key witness in Stein's prosecution of evolution, from a 2000 speech at the National Religious Broadcasters convention in Anaheim, Calif.: "Intelligent design opens the whole possibility of us being created in the image of a benevolent God…. And if there's anything that I think has blocked the growth of Christ as the free reign of the spirit and people accepting the Scripture and Jesus Christ, it is the Darwinian naturalistic view."

When will people learn that Darwinian naturalism has nothing whatsoever to do with religious supernaturalism? By the very definitions of the words it is not possible for supernatural processes to be understood by a method designed strictly for analyzing natural causes. Unless God reaches into our world through natural and detectable means, he remains wholly outside the realm of science.

So, yes Mr. Stein, sometimes walls are bad (Berlin), but other times good walls make good neighbors. Let's build up that wall separating church and state, along with science and religion, and let freedom ring for all people to believe or disbelieve what they will.
