I've followed this issue for years. Until you showed up, I never met anyone who mentioned Pasteur's work relating to this in the least.
That's because you've been following the evolutionist's narrative for years, which, among other things, confounds the classical rendition of irreducible complexity and its scientific expression as applied to prebiotic chemistry, with Behe's rendition, which is obviously false, a straw man.
Politics? Syllogisms? Analogies? The matter is ultimately one of scientific research, experimentation, and falsification.
There is a whole other world of ID thought out there that has always begun with Pasteur's law for obvious reasons and proceeds accordingly.
On the other hand, the ID establishment is compelled to address the Darwinian notion of a common ancestry as well and that is where most of the energy is focused. Here the matter becomes less scientifically scrutable, as specified complexity and probability are inversely related and are predicated on the methodological naturalism of classical empiricism.
Is it unreasonable to conclude that highly complex and specified biological infrastructures and systems were designed rather than achieved by a mindless, stochastic and ultimately unquantifiable mechanism of natural causality?
No.
Are such calculi scientifically verifiable in any empirical sense?
Maybe. Maybe not. If not today, maybe in the future. If not now, maybe never.
And so the evolutionist will say that the calculi of specified complexity abuse the art of mathematical probability because the mathematician, whether his guesses be reasonable or not, presupposes a set of parameters that cannot be empirically substantiated. So not only is specified complexity as applied to speciation bad science or pseudo science, it's bad math because its calculations allege to show something about reality that may not be true. If the parameters are wrong, the calculation is useless. Think a syllogism whose conclusion is valid because it duly follows from the major and minor premises, but because the premises are absurd, the conclusion, however valid, is not true. So goes the evolutionist's criticism.
But what the evolutionist never tells you is that the parameters of his algorithms are a collection of educated guesses, too, starting with the jumping off points of the supposed incremental processes of complexity, which are calculated on the basis of known outcomes. The mechanisms of the pathways are presupposed, too, and the pathways themselves are in reality unpredictable but for the convenience of the known outcomes. LOL! None of the parameters but the known outcomes can be directly or empirically substantiated.
Are the Darwinian algorithms necessarily unreasonable?
No.
But the evolutionist is merely saying that a known outcome must have necessarily been achieved by a random chain of mutations within a medium of constants because, after all, the various species are here in the forms that they are, and the parameters of the Darwinian algorithms do in fact allow for the processes to arrive at the known destinations. Hence, the outcomes are specified, but not complex in the sense of their derivations.
Ultimately, the evolutionist's characterization of specified complexity is based on his rejection of the methodological naturalism of classical empiricism in favor of a methodological/absolute naturalism, an apriority that might be wrong.
The argument that ID is not scientifically valid with regard to prebiotic chemistry is nothing more than the bigotry of intellectual dishonesty and the blather of political sloganeering.
The argument that ID is not scientifically valid with regard to the history of speciation is arguably true, albeit, only when one disregards the validity of a classical naturalism. In what sense is the construct of a common ancestry scientific other than the fact that a majority of scientists say so as they embrace a metaphysical apriority that begs the question?
