It does seem true that Berlinski is short on answers of his own. I think he is perhaps best seen as a Socrates questioning the Sophism of the modern Scientific Establishment, especially the sort who like to sermonize about "The Science," or even worse conflate "The Science" with themselves. He's a gadfly harrying the polis that is science pointing out its arrogance and its self-contradictions. When dealing with the speculative intangibles that are theoretical physics and cosmology, he may not be at his best. I think his finest moments are when he is taking down the colossal hubris (and fraudulent practices) of the most extreme modern Darwinists, as he does in The Devil's Delusion.
