Thanks Jim for notice of Mike's book. I ran out to my local Barnes and
Noble Booksellers here in Grand Rapids and there were five copies on
the shelf. And, yes, I did contribute to Mike's royalties.

Congratulations to Mike for his book and for the forceful statement of
his argument, well summarized by Jim's glowing blurb!

I have my own take on Mike's thesis and hope to do a formal review of
the book at some point. Mike and I "debated" his point at the ASA
meeting at Bethel College in 1994. Here is the abstract of my
contribution. The full talk is now on the web at

ABSTRACT

Complexity--Yes! Irreducible--Maybe! Unexplainable--No!

A Creationist Critique of the Irreducible Complexity Argument for
Intelligent Design

Irreducible complexity has long been used by Creationists as an
argument against evolution. The classic example is the origin of the
eye. It is hard to imagine how natural selection could have produced
in stepwise fashion such a complex system with so many interworking
parts; therefore such systems are explained by appeal to "intelligent
design".

The irreducible complexity argument has recently been advanced again
in the context of various systems that are observed at the cellular and
molecular level in organisms. Protein structure, cilia and flagella,
and protein targeting have been cited as examples of irreducibly
complex systems.

I will respond to the irreducible complexity argument in four ways.
1) The entire universe, as the product of God's creative and governing
hand, is designed, even when we can account for its various features
with scientific explanations. 2) Hemoglobin, the oxygen transporting
protein of the blood, is a complex molecular machine. Although
hemoglobin is a fairly simple system compared to a cilium, I believe
that comparative studies of hemoglobin at the protein and gene level
have suggested to us how such molecular machines might come about. 3)
The relatively new science of complexity theory may provide a
non-Darwinian solution to this problem. A property of complex systems
far from thermodynamic equilibrium is that order and new properties
arise spontaneously. 4) Premature appeal to special divine activity
to explain the world around us damages the Christian theistic
apologetic.
