Dembski seems to be using a quantitive approach to demonstrate that novel biostructures could not have arisen as a result of either chance (or rather, that the improbability is such that it is as good as impossilbe [he multiples the number of quarks in the cosmos by the number of plank moments or something like that to get the denominator for the inverse of his threshold of so-improbable-that-it-is-as-good-as-impossible) or necessity. He concludes that these forms have arisen as a result of specified complexity. But the specified in this term is another name for something that a rational being, especially an engineer, would think of. So it's kind of a way of talking about teleology via quantification.
Here is a summary and comments on the essay Freedom and Resentment by PF Strawson. He makes some great points, and when he is wrong, it is in such a way as to clarify things a great deal. My non-deterministic position is much better thanks to having read this. I’ll summarize it in this post and respond in a later one. In a nutshell: PFS first argues that personal resentment that we may feel toward another for having failed to show goodwill toward us would have no problem coexisting with the conviction that determinism is true. Moral disapprobation, as an analog to resentment, is likewise capable of coexisting with deterministic convictions. In fact, it would seem nearly impossible for a normally-constituted person (i.e., a non-sociopath) to leave behind the web of moral convictions, even if that person is a determinist. In this way, by arguing that moral and determinist convictions can coexist in the same person, PFS undermines the libertarian argument ...
