This volume provides an authoritative overview of Government and Binding Theory, and - in crucial new papers by Noam Chomsky and Alec Marantz - of the subsequent development of the Minimalist Program. Written by a group of internationally respected researchers, each chapter is focused on an individual module of the theory. Articles describe the current development of and state of work on a particular topic; its place within the architecture of the GB approach to linguistic structure; and the prospects and need for change within the module. The final chapter consists of Chomsky's work "Bare Phrase Structure" which represents his latest thinking on his revolutionary "Minimalist Program". The contributors and the topics covered are: Gert Webelhuth (X-bar Theory and Case Theory); Edwin Williams (Theta Theory); C. T. James Huang (Logical Form); Wayne Harbert (Binding Theory, Control and Pro); Norbert Hornstein Randall Hendrick (Morphosyntax); Alec Marantz (The Minimalist Program); and Noam Chomsky (Bare Phrase Structure).
