DDD # 18 is a particularly contemptible form of ad hominem, which Mark Frank and Elizabeth Liddle do us the service of demonstrating in the combox to this post. In the post Dr. Torley refers to Darwin’s Doubt by Dr. Stephen C. Meyer, which explains many of the shortcomings of various Darwinian narratives. Frank and Liddle tag team for a DDD #18:
[Meyer] explains perceived weaknesses in his understanding of evolutionary theory but gives no reason why design is a better alternative.
Exactly. His understanding of evolutionary theory is weak, and actual evolutionary theory is a better alternative.
Follow this link and take a look at what scientists who actually know what they are talking about have said about Darwin’s Doubt. A sample:
Darwin’s Doubt is by far the most up-to-date, accurate, and comprehensive review of the evidence from all relevant scientific fields that I have encountered in more than forty years of studying the Cambrian explosion. An engaging investigation of the origin of animal life and a compelling case for intelligent design.
Dr. Wolf-Ekkehard Lönnig, Senior Scientist Emeritus (Biologist) at the Max Planck Institute for Plant Breeding Research
Darwin’s Doubt is an intriguing exploration of one of the most remarkable periods in the evolutionary history of life—the rapid efflorescence of complex body plans written in the fossils of the Burgess Shale . . . No matter what convictions one holds about evolution, Darwinism, or intelligent design, Darwin’s Doubt is a book that should be read, engaged, and discussed.
Dr. Scott Turner, Professor of Biology, State University of New York
Does anyone believe that numerous highly-credentialed scientists, many of whom specialize in biology, would recommend Meyer’s book if his “understanding of evolutionary theory is weak”? Of course not. What does this mean? It means that Elizabeth Liddle’s statement is false. I will leave it to others to debate whether she is merely too muddle-headed to understand that she has made an egregiously false ad hominem attack as a substitute for argument, or she knows the truth and has deliberately misled. The point is that either way, Liddle has avoided having to actually defend against Meyer’s claims by simply dismissing him as too stupid to understand why Darwinists like her are smarter than he. And that is contemptible.
