Noam Chomsky's work has had a decisive influence on the development of linguistics and more broadly on the study of mind and language. This book, which contains two new papers by Chomsky, assesses that 'Chomskyan Turn' in linguistics and the cognitive sciences. The articles by Chomsky Linguistics and Adjacent Fields and Linguistics and Cognitive Science are particularly valuable both in reviewing the current state of the generative enterprise and in presenting his new 'functional' approach to principles of Universal Grammar. The concluding papers focus on syntactic issues in Government and Binding.
