Lewis was right after all

This passage comes from A. N. Wilson's "Why I Believe Again." 

Watching a whole cluster of friends, and my own mother, die over quite a short space of time convinced me that purely materialist "explanations" for our mysterious human existence simply won't do - on an intellectual level. The phenomenon of language alone should give us pause. A materialist Darwinian was having dinner with me a few years ago and we laughingly alluded to how, as years go by, one forgets names. Eager, as committed Darwinians often are, to testify on any occasion, my friend asserted: "It is because when we were simply anthropoid apes, there was no need to distinguish between one another by giving names."

This credal confession struck me as just as superstitious as believing in the historicity of Noah's Ark. More so, really.

Do materialists really think that language just "evolved", like finches' beaks, or have they simply never thought about the matter rationally? Where's the evidence? How could it come about that human beings all agreed that particular grunts carried particular connotations? How could it have come about that groups of anthropoid apes developed the amazing morphological complexity of a single sentence, let alone the whole grammatical mystery which has engaged Chomsky and others in our lifetime and linguists for time out of mind? No, the existence of language is one of the many phenomena - of which love and music are the two strongest - which suggest that human beings are very much more than collections of meat. They convince me that we are spiritual beings, and that the religion of the incarnation, asserting that God made humanity in His image, and continually restores humanity in His image, is simply true. As a working blueprint for life, as a template against which to measure experience, it fits.

What Wilson has seen the force of, here, is the argument from reason, which was the argument that, in Wilson's own biography of Lewis, Anscombe is credited with demolishing so thoroughly that he was driven into to write children's fantasies instead of Christian apologetics. His was the most virulent version of what I have called the Anscombe Legend, the legend that Lewis critic John Beversluis (who had employed it in the first edition of his book on Lewis) dispatched with the following critique. 

First, the Anscombe debate was by no means Lewis's first exposure to a professional philosopher: he lived among them all his adult life, read the Greats, and even taught philosophy. Second, it is simply untrue that the post-Anscombe Lewis abandoned Christian apologetics. In 1960 he published a second edition of Miracles in which he revised the third chapter and thereby replied to Anscombe. Third, most printed discussions of the debate, mine included, fail to mention that Anscombe herself complimented Lewis's revised argument on the grounds that it is deeper and far more serious than the original version. Finally, the myth that Lewis abandoned Christian apologetics overlooks several post-Anscombe articles, among them "Is Theism Important?" (1952)—a discussion of Christianity and theism which touches on philosophical proofs for God's existence—and "On Obstinacy of Belief"—in which Lewis defends the rationality of belief in God in the face of apparently contrary evidence (the issue in philosophical theology during the late 1950s and early 60s). It is rhetorically effective to announce that the post-Anscombe Lewis wrote no further books on Christian apologetics, but it is pure fiction. Even if it were true, what would this Argument from Abandoned Subjects prove? He wrote no further books on Paradise Lost or courtly love either.

Language is a product of our ability to reason, and it if is to be explained naturalistically, it has to be as much a product of evolution as a finch's beak. If this is deeply problematic for evolution, then he is essentially embracing the conclusion that Peter Geach, Anscombe's husband, came to when he wrote: 

When we hear of some new attempt to explain reasoning or language or choice naturalistically, we ought to react as if we were told that someone had squared the circle or proved the square root of 2 to be rational: only the mildest curiosity is in order-how well has the fallacy been concealed?] P. T. Geach (The Virtues). 

But to do that is to accept the conclusion of Lewis's AFR.
