If there had been good arguments for a genetically determined grammar, I'msure Pinker would have mentioned them, so I consider this book a very good indication that thetheory is a wild guess at best.
Still, Pinker is an excellent stylist, and his collection of factsis extremely interesting taken individually. For these reasons alone the book is well worth reading.
Pinker, one of theacknowledged greats in the 30-year-young field of linguistics, explores the ability of humans tothink and to communicate in language from a variety of angles and with reference to many differentfields of study.
Topics covered include: - the structure/grammar of language and forcomparative languages - the 'correctness' of standard American English and self-designated"language mavens". - structures and regions of the brain which seem to control our ability to speak - observations on the relationship between age and learning language - evolutionary theory andhow come only humans can talk? - universal characteristics of all human cultures and all humangrammars - animals who have been trained to "talk"
Pinker may or may not be 100% right, but histhinking is clear-headed and his view of humanity is refreshing, in that it is both broad enough tocover every speaking (human) culture, and specific enough to rely on individually observed andexperimental evidence in describing the ways we learn.
