I agree with your general point about the confounding of anti-evolutionism with ID in the public mind. I even agree that ID people haven’t always done enough to combat this misperception. But here, I hope you and I can discuss these things as theoretical men, not as analysts of culture-war activity. The interesting parts of ID are its thoughts on design detection, its critique of neo-Darwinism, its highlighting of the latest results of secular thought on evolutionary mechanism, and its broader methodological ruminations. I’m interested in ID as part of a general intellectual movement, including many non-ID scientists and thinkers, interested in reformulating thought on evolution, the nature of life, and scientific method. I like discussing things at the high level. All the stuff about courts and ENV columns etc. depresses me.
Not in all cases. Collins argues for God, for example, from the existence of moral conscience, an approach which Behe would not disagree with. Also, on the origin of life, Collins has remained open to the possibility that it might require some special intervention, i.e., because it seems to be a stretch that it happened by accident. Behe also would find it a stretch that it happened by accident. And on the fine-tuning of the cosmos they would have some common ground. It is really mainly on evolutionary biology that they would disagree, and even there, not on age of the earth or even common descent, but only on mechanisms. And it would an odd thing if disagreement over the mechanisms of evolution should be enough to prevent two Christians from working together against two atheists.
Also, in such a scenario, Behe and Collins would have weeks or months of notice, and they could get together and hammer out a best common strategy for the debate. It’s not as if they would be yanked out of their offices and told they would be debating Coyne and Myers in an hour.
In fact, however, even before his NIH appointment, Collins was deeply averse to meeting ID people on stage, even as an opponent. I saw him speaking on podcasts, etc., and he would speak against ID people (usually misrepresenting their views in some way), but I never saw him speaking to ID people. So the main reason such a teaming would not take place is partisanship – a disinclination of Collins to even try to find common ground with fellow-Christians – the very opposite of the approach here at Peaceful Science, where Joshua tries to find common ground not only with ID folks but even YECs. Thus, for all Collins’s gentleness as a person (and he seems to be a nice guy), he behaves tribally when it comes to ID. The ID folks rub him the wrong way. It’s that tribal dislike between ID and TE that prevents them from working together, even against enemies that would destroy them both if they could, and thus makes them less effective Christian witnesses against atheism than they could be.
