This book is just pure silliness. Lacking in subtlety, straw-manning opponents, not up to date with the latest in linguistic theory, the author tries to argue against linguistic nativism. In the beginning of the book it seemed weird to me that he was taking arguments from popular linguistics books and attacking a disproportionate version of those, but at the end it became apparent why he was doing this. The author is a dualist, an anti-determinist, he believes minds are different from brains, and minds use brains. Biology has nothing to do with the ideas we produce, or the way we think and behave. He then ends the book by basically urging the readers to accept this vision on Man, since it presents a far nobler depiction of human nature. As if nature bends itself to our puny desires
To start with, I don't think the author fully understands what the nativists are actually saying. This is was I mean by straw-men and exaggerations and a complete lack of subtlety. Along with language, the author thinks the nativists are saying that we have genetically built-in knowledge about very specific things. like one specific individual language, or possibilities for scientific ideas, and therefore creativity is ruled out. I don't think one can find many modern nativists arguing that we are born with knowledge so specific such as scientific theories or how to use a washing machine. What is innate is the predisposition and ability for language, not Japanese or Italian. I don't think the author is misrepresenting the nativist case on purpose, I think he just doesn't understand it.
Then there is the dislike for the idea that biology constrains our behavior and ways of thinking. Clearly he has never spoken to a biochemist, or to a depressed person for that matter. Or is it a sign of the creativity of the *mind* that we think of suicide when we are depressed? Yet, a successful suicide end up killing the brain. Like it or not, we are heavily constrained by our biochemistry, and there is nothing we can do about it except to change the biochemistry. Culture and biology are not mutually exclusive, the different cultures we see are just as biologically-based as languages are. What would be interesting and would make his case is to see a culture that is disallowed by biology.
If you want a good laugh, read the book. Otherwise, it is really not worth the trouble
