New in paperback. Hardcover was published in 2009. This book presents a state-of-the-art account of what we know and would like to know about language, mind, and brain. Chapters by leading researchers in linguistics, psycholinguistics, language acquisition, cognitive neuroscience, comparative cognitive psychology, and evolutionary biology are framed by an introduction and conclusion by Noam Chomsky, who places the biolinguistic enterprise in an historical context and helps define its agenda for the future.
