Throughout the evening, Stephen Meyer kept repeating that we only know of “specified information” occurring because of an intelligent agent acting. Then, because we only know one cause in the present for “specified information”, we should accept that as the cause of “specified information” in the past.
Besides the philosophical problems with rarefied design inferences, there is the rather more simple class of empirical counterexamples. To wit, Meyer has consistently ignored available evidence that is not in accord with his outlook. What designer, for example, must be posited as acting in any of the various cases of duplicated genes that diverge and where the copies now each yield different functional protein products? Meyer has been ignoring this despite notice in 2004 of this class of evidence.
