Willard has an excellent talk on the nature of moral knowledge in the university. It's well stated, although a bit grainy in the audio. The lecture can be found here as part of the Veritas forum: “The university no longer offers a body of moral truth, the closest you get to it is freshman orientation."
San Elijo College believes that there is a body of moral knowledge found in both natural law, as defended in C.S. Lewis' "The Abolition of Man" and by the majority of the great writers of the West. In addition, the College believes that the Christian tradition, as stated in the Nicene Creed, is a knowledge tradition, and in that knowledge tradition, there is a clear body of moral knowledge that regulates human life.
