In the final analysis, science is not more provable as knowledge than religion is; it is the nature of scientific knowledge to be contingent. Science is not about knowledge or provable facts; science is about a process. Incidentally enough, so is religion. However, religion and science are in completely different spheres of inquiry; a good scientist with an understanding of the epistemological underpinnings of their avocation will understand that science cannot comment on statements of faith, while a good theologian with a good understanding of the epistemology of their faith will understand that attempts by a church (xtian, muslim, or other) to legislate the nature of nature are doomed from the start.

Can't remember if it was Popper or some other dude that first pointed that out... Foucault, maybe (my epistemology classes were ten years ago now). Either way, the argument is compelling and should be read by anyone that wants to discuss science and scientific discovery in any meaningful way.
