Query: An exciting book

OK, there are frequent fuzzy patches, and the author doesn'tknow what the phrase "beg the question" means (p. 228), butthere are enough really interesting ideas to carry the book.For instance, that Chomsky's arguments ignore selection effectson languages; or that human laughter and sobbing are calls(like other animals' calls), which makes it easy to see that language isn't like animal calls, only more complicated;or that the syntax-semantics distinction might have been driven by the computational processing constraints of the evolving humanbrain. And it's got a big picture of the co-evolution oflanguage and the human brain which is worth thinking about.It's an exciting book.
