complexity

Whenever biochemist Michael Behe’s argument for design from “irreducibly complex” molecular machines appears, there is a Darwinist waiting in the wings with a devastating critique (or so he thinks).

Take as an example the following passage from biologist Craig M. Story. He recently reviewed Fazale Rana’s new book The Cell’s Design for Christianity Today (see “Same Song, Second Verse“). In his review, he critiques Behe’s argument, because according to Dr. Story, Rana merely regurgitates Behe.

Rana, like Behe before him, may be commended for providing a layman’s description of a number of astonishingly intricate cellular processes. But his portraits of cellular workings will fail to convince most mainstream scientists for the same reason that Behe’s book has been roundly dismissed: The analogy between manmade machines and cells is a poor one at best. Cellular components, although machine-like in some respects, do not behave like manmade machines. They self-assemble and self-manufacture, and they are able to transform available energy sources such as light to fuel metabolic activity.

Now what’s wrong with this reply? Didn’t we all learn from Hume that arguments from analogy are inherently weak?
