Point Counterpoint offers a series of papers and replies originally presented at a special session of the Second Language Research Forum, UCLA, March 1989. The focus of the papers is primarily the role of Universal Grammar in second language acquisition, though the agenda also includes discussion of other fundamental questions, viz., the explanatory potential of linguistic theory in native-language development. It may come as no surprise that the contributors and their respondents often present very different perspectives on the issues, for most of the authors were known in advance to hold contrasting points of view. Contributors (c) and Respondents (r) are: Wolfgang Klein (c)/Nina Hyams (r); Sascha Felix (c)/Jacquelyn Schachter (r); Suzanne Flynn & Sharon Manuel (c)/David Birdsong (r); Lydia White (c)/Robert Bley-Vroman (r); Peter Jordens (c)/Lynn Eubank (r); Jurgen Meisel (c)/Bonnie Schwartz (r); Sharon Hilles (c)/William O'Grady (r); Daniel Finer (c)/Margaret Thomas (r); Usha Lakshmanan (c)/Nina Hymans & Ken Safir (r).
