Trask, S. W. 2006. Evolution, science, and ideology: why the establishment clause requires neutrality in science classes. Chapman Law Review 10:359.
The article isn't available on line, and I haven't seen a hard copy, so you'll have to refer to the posts above for a detailed analysis. I just want to point out that Sandefur gets the title of his post right, “All epistemologies are not created equal.” It's right because, as Sandefur notes, the scientific method has proven itself unequaled as a method of learning about the observable world. And it's right because Sandefur correctly locates the argument about the status of revelation, religious belief, and other ways of knowing as an argument about epistemology, i.e., an argument in philosophy, not science.
In that sense, Sandefur's argument goes even further than is necessary. He argues that science and reason are the only legitimate source of knowledge about the world. But to show that creationism doesn't belong in science classes we don't need to deny the legitimacy of religious belief, and we don't need to claim that science is the only legitimate source of knowledge about the world. We only need to show that creationism doesn't follow the norms and practices of science, a task that's been repeated innumerable times.
For the record, the philosophical arguments in favor of science as the only legitimate source of knowledge convince me. But I have not thought deeply enough about metaphysics to be sure that the arguments are right. That's why I will treat those with deeply held religious beliefs with respect – provided they return the favor.
