In an interview about his book Darwinian Conservatism, Larry Arnhart makes this statement:
In my book, I explain why the arguments of the intelligent design folks are weak. They assume unreasonable standards of proof in dismissing the evidence for Darwin's theory, and they don't offer any positive theory of their own as an alternative.
Note that he doesn't say that he explains "...why, in his opinion, the arguments of the ID folks are weak." Nosiree. No sissified qualifications or equivocations from this man. Arnhart is a political science professor, after all, and if such an exalted expert proclaims the ID arguments to be weak, then that settles that.
Professor Arnhart is evidently convinced that a professorship in political science is close enough to real science to give him sufficient standing to pontificate on controversies in the philosophy of science as though he had some authority in the field. This is almost as presumptuous as Ann Coulter's pronouncements on the short-comings of the theory of evolution in her book Godless.
To be sure, there's nothing wrong with a non-specialist venturing opinions on matters outside their field of expertise - at Viewpoint we do it all the time - but it would be wise of non-specialists to exercise a little intellectual humility and avoid presenting their opinions as if they commanded the assent of the rest of us.
