Thomas B. Fowler has written an outstanding and disinterested analysis of Intelligent Design theory for Catholic Culture. It is, for the most part, very accessible to those with a modicum of philosophical and scientific background knowledge and I recommend it to anyone who wishes to gain a better understanding of the scientific status of ID and an appreciation its strengths and weaknesses.
Fowler also does a fine job of summarizing ID's chief competitors including Creationism, Neo-Darwinism, and Meta-Darwinism.
His conclusion gives us a good idea of the terrain he covers in the main body of the discussion:
Intelligent Design has been proposed as a new scientific hypothesis about the possibility of certain types of transitions occurring naturally. The thrust of its proposal is that biological (and other) entities may be partitioned into groups or classes within which transitions are possible, but between which they are not. This is an empirically testable hypothesis, one which contradicts a key assumption of Neo-Darwinism. As yet, only preliminary steps have been taken to formulate and test this hypothesis: Behe's irreducible complexity and Dembski's Design Filter. So no definitive statement about its truth can be made as yet.
Of course, there is no guarantee that the Intelligent Design school will be able to reach its goals; nature may not be the way the theory postulates that it is. The notion of an "Intelligent Designer," for which the school is perhaps best known, is not part of its scientific basis, but rather an inference from it, or rather, an inference about reality based on the physical limitations in nature that the theory proposes. The school is, in some ways, its own worst enemy by not clearly distinguishing its scientific hypotheses from the extra-scientific inferences it draws.
Intelligent Design does not deny naturalism - that is, it does not require science to begin utilizing non-natural forces and entities. It does dispute metaphysical naturalism, which asserts that all phenomena can be explained by science and that there is no other reality. But the latter assertion is a metaphysical inference from the former, which is itself an extra-scientific assumption. The common attacks on Intelligent Design, accusing it of being Creationism in disguise, a Trojan Horse, and of injecting theology into science, are completely baseless. Its critics should therefore concentrate on the scientific issues raised, ignore the metaphysics and eschew the propaganda arguments, however satisfying these may be. But Intelligent Design must also deliver on the science.
