The first link below is from an event written up in the Weekly Standard last week. Both links were sent by the Discovery Institute.
I've heard Arnhart before, and have never found anything particularly compelling in his approach. If there is a biological nature given by Darwin's mechanism of natural selection, I still don't see why one can't argue that humans have evolved to the point that we can transcend whatever it is we want to transcend--or at least try to do so. If we fail, then, so what? Sort of like monkeys reaching for bananas too far out on the limb, we might fall and get eaten by a lion. Sounds like more survival of the fittest, to me. Whatever. Species just do what they do. Including stupid things in the case of humans. I prefer something like "natural law" given by the Creator (by design). I fail to see why we need Darwin to give us a fixed biological nature. It doesn't seem to me, layman that I am, that there is anything particularly "fixed" in Darwin's scheme.
Anyway: from Discovery:
To see or listen to “Darwinism and Conservatism: Friends or Foes?” at the American Enterprise Institute, featuring John West, George Gilder, Larry Arnhart, and John Derbyshire, go here.
And to listen to Dr. John West’s lecture “Darwin’s Dangerous Idea: The Disturbing Legacy of America’s Eugenics Crusade” at the Family Research Council, go here.
