Here is a good review by Doug Groothuis of a recent talk that Michael Shermer gave in Denver. While I didn’t see this particular talk by Shermer, I did see him talk a few years ago, and it sounds like nothing’s changed; Groothuis’s critiques are mostly on-target.
I’m mentioned in one part of the review:
Shermer emphasized that creationists and ID thinkers believe that Darwinism leads to atheism which leads to relativism and social decay. He said, “It’s all about worldview.” His argument seems to be that since there is no good science involved, the challenge to Darwinism can be reduced to a political agenda. But Shermer did nothing to refute the idea that atheism can lead to relativism and social decay—besides scoffing at the idea. …
More importantly, the social motivations of critics of Darwinism and defenders of design are utterly irrelevant with respect to the science they are assessing. What counts are their arguments. To attack motives in order to discredit arguments is to commit the fallacy of poisoning the well. Bradley Monton, an atheist who is sympathetic to ID, makes just this case in Seeking God in Science.
