This series about intelligent design and creationism has briefly covered the nature of scientific knowledge , the issue of scientific credibility, religious agenda and the science/religion conflict. The web sites listed below provide a more in-depth coverage. However, I recommend the lecture by Eugenie C. Scott for an excellent overview on the nature, history and problems of intelligent design and creationism. (She even covers a positive outcome for science resulting from the intelligent design campaign).
To watch a video of this lecture go to the University of Washington TV link.
