The library has slim pickings on linguistics, but it happened to have a couple of books on opposite sides of the innatism debate: Ray Jackendoff’s Patterns in the Mind, and Daniel Everett’s Language: The Cultural Tool.

Overall judgment: both books are full of interesting things; both are extremely convinced of their position; both reduce their opponents (i.e. each other) to straw men.
It’s a lesson, I suppose, in letting one’s speculations get ahead of the evidence. Many a Chomskyan book has a long annoying section on how children could not possibly learn language; the arguments are always the same and they’re always weak. The Chomskyans’ problem is that they don’t spend five minutes trying to think of, or combat, any alternative position. They present the “poverty of the stimulus” as if it’s an obvious fact, but don’t do any actual research into child language acquisition to show that it’s really a problem.
Yet Everett doesn’t do much better on the other side. He’s all about language as a cultural invention, and he mocks the Chomskyans’ syntax-centrism and their inability to explain how or why Minimalism is embedded in the brain and the genome, but he doesn’t really know how children learn languages either.
My sympathies are far more with Everett, but an honest account has to admit: we just don’t know. Well, the third book I picked up is a massive tome called Language acquisition and conceptual development, so I’ll report back if it turns out we do know.
Sometimes the two authors cover the same facts– e.g. what’s going on with Broca’s and Wernicke’s areas in the brain. Their account is different enough that it seems that both are cherrypicking the data. Jackendoff doesn’t mention the non-linguistic functions of these areas, while Everett pooh-poohs that they’re language-related at all.
What ends up being most valuable about both books is when they’re talking about other things. Everett is full of stories about Amazonian peoples and languages; Jackendoff has a very good section on ASL. (They both also have quite a bit of introductory linguistics, which I could have used less of. Sometimes it’s a pity that academics only have two modes, “write for the educated high schooler” and “write for each other”. I suspect their editors overestimated just how many people entirely ignorant of linguistics would read each book. I guess I’m lucky that readers of my more advanced books can be assumed to have read the LCK.)
I don’t mean to sound entirely dismissive. In fact Jackendoff makes the Chomskyan case about as well as it can be made (far better than Chomsky ever does); but if you find him convincing, make sure you read Everett to get a fuller perspective.
(I may also be unfair to Jackendoff calling him a Chomskyan; apparently he’s broken with Minimalism. He also makes a point, when pointing the reader to books on syntax, to include a wide range of theories, something Chomsky himself and his acolytes don’t bother to do.)
