The Language of God, Chapter 9
By B.J. Marshall
The subtitle to this chapter is “When Science Needs Divine Help,” which immediately sets up a couple of problems. First, is Collins asserting that Intelligent Design (ID) is science? Second, where does divine help fit in with the application of the scientific method? In response to the first, Collins concludes that ID is not science. He doesn’t really address the second problem. That second problem brings to mind a quote by J.B.S. Haldane:
My practice as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world.
Focusing on that first problem, we want to see whether ID is a valid scientific endeavor. According to Collins, the ID movement rests upon three propositions:
- Evolution promotes an atheistic worldview and therefore must be resisted by believers in God (p.183)
- Evolution is fundamentally flawed, since it cannot account for the intricate complexity of nature (p.184)
- If evolution cannot explain irreducible complexity, then there must have been an intelligent designer involved somehow, who stepped in to provide the necssary components during the course of evolution (p.186)
Collins doesn’t really address the first claim at all. He states right up front that Phillip Johnson, the founder of the ID movement, was more interested in defending the faith than by a “scientific desire to understand life (he makes no claim to be a scientist)” (p.183). Referencing the “wedge document,” which “was originally intended as an internal memorandum but found its way onto the Internet” (p.183), Collins concludes that ID is not science. It fails to make predictions, is an unfalsifiable position (Collins says one couldn’t verify it “outside of the development of a time machine” (p.187), and makes no claims providing a mechanism by which the postulated supernatural interventions would give rise to complexity. (Here’s another example of where double-standards apparently elude Collins. His own position, that every naturalistic explanation just shows you how God works, seems to be an unfalsifiable position; even if we were to somehow explain the Moral Law, that would just show you how God works.)
The proposition Collins seems to be refuting here is “ID is science.” He doesn’t address the proposition as stated of whether evolution promotes an atheistic worldview. I found this very interesting, given that this would have been a perfect time for Collins to once again drive home his thesis of theistic evolution. He tore down Johnson’s claim without ever reminding readers of the alternate case that is the main thesis of this book. Fail.
Collins does a much better job addressing the second proposition. He addresses the problems of irreducible complexity with examples such as the evolution of eyes, the bacterial flagellum, and the human blood-clotting cascade. He also talks about the suboptimal design in eyes, which seems problematic. Ultimately, he concludes that claims to irreducible complexity are just arguments from ignorance.
So one can see how ID is getting really close to the edge of where Collins wants to take theistic evolution, but ID just can’t seem to cross that line. And the next chapter will bring us there. Collins concludes this chapter on Intelligent Design with an exhortation. He starts by citing William Dembski, who said in “The Design Revolution”:
If it could be shown that biological systems that are wonderfully complex, elegant, and integrated – such as the bacterial flagellum – could have been formed by a gradual Darwinian process (and thus that their specified complexity is an illusion), then Intelligent Design would be refuted on the general grounds that one does not invoke intelligent causes when undirected natural causes will do. In that case, Occam’s razor would finish off Intelligent Design quite nicely (p.194 of The Language of God).
Of course, one cannot expect Dembski to just let ID die, but that’s as separate an issue as the fact that Collins has pushed God so far back that Occam’s razor can’t even touch it. Collins instead focuses on the question of what happens to a believer’s faith when one can no longer give God a resting place in ID. Take away ID, and where does that leave God?
Enter what Collins calls BioLogos.
