Then let’s be clear: Behe has responded on the Internet to recent criticisms from scientists. He just hasn’t responded on the Internet to your criticisms or Art’s.
I’ve already suggested that you, yourself, Dr. Swamidass, should be able to formulate a response that Dr. Behe could make to your counterexample of endosymbiology. You claim to be familiar with Dr. Behe’s books. If so, then you already know what he has written about Lynn Margulis’s views. And that should give you a really big clue as to how he would respond to your counterexample
Art’s ol’ T-urf13 has been around for years. I discussed it with him way back at the website TelicThoughts. That website no longer exists, so perhaps we need to have that conversation again.
The stone bridge example? It begins with three stones in a row. Remove any one of them, and the bridge no longer exists. So we begin with an IC system. The fact that it evolves into a slightly more complex IC system doesn’t seem to be a huge problem for Behe’s argument.
Lastly, your claim that Behe has different definitions of ID, and this somehow poses a major problem for him. To be honest, I don’t see how it does. Assume his first definition is the one to go with. Where’s the problem for him?
