I sent Maureen's post about Terrence Deacon's critique of Chomsky to Chomsky, who replied below.

Dennis,

Deacon's book was reviewed as soon as it came out by Robert Berwick, a very prominent computer scientist, with an extremely strong background in biology, linguistics, and psycholinguistics. He tried to be polite, but was able to do so only by keeping to the neuroanatomy, which is solid. He mentioned the work on language, dismissing it (politely) as worthless. There is a devastating critique by Lyle Jenkins, _Biolinguistics: Exploring the Biology of Language_ (Cambridge U, 2000). Jenkins is an outstanding linguist who has been working in biology for 25 years, and is highly expert. Jenkins did try to get Deacon to explain some of his outlandish ideas in scientific conferences, but it was hopeless; at some level, he presumably recognizes the absurdity, and just avoids discussion, so Jenkins and other participants report.. I've written a little about it, but not much; could send you if you are interested, but don't see why you should be. Others haven't written about it much either, because it is an embarrassment. He hasn't a clue about the work in linguistics to which he alludes -- in such a vague way that it is not easy to trace his often comical errors to the source; probably some second-hand gossip he heard. His own proposals are sheer mysticism: "language" is some extra-human entity that "co-evolves" with humans and then mysteriously "attaches" to people (like a parasite and a host). So my granddaughter in Massachusetts has one of these parasites, and my granddaughter in Managua has another (actually two, since she's bilingual). It surpasses silliness, which is why there isn't much in the way of discussion.

Glad to hear about the Voice exchange. If you have copies of Hentoff and your response I'd like to see them. I've been collecting some of the recent nauseating accolades to this self-confessed mass murderer, and read the Hodgson biolgraphy and reviews of it. Everyone talks about his noble time in the UN, standing up forthrightly against Idi Amin and defending Israel (which takes enormous courage in New York). I have yet to see a single word referring to his proud description of his responsibility for undermining any UN action to impede Indonesia's invasion -- which must be one of the most extraordinary passages on record, describing what is surely the most important act of his life (he casually notes that 60,000 were killed in the first few months, pretending that this had to do with the "civil war" that was over months earlier, and then goes on to another topic. I'm surprised at Hentoff. He's been away from the activist solidarity scene for decades, as far as I know, but he surely must have known about this, if only from his earlier contacts in the pacifist nonviolent community.

Noam
