RHETORICS OF HOPE AND FEAR IN THE GREAT EMBRYO DEBATE

Legislation designed to control the conduct of research on human embry os was introduced in Britain in 1990. During the preceding debate, the re had been widespread public discussion concerning the rights and wro ngs of such research. This study examines some of the rhetorical resou rces used in the final parliamentary debate to support and oppose the continuation of embryo research. Two distinctive rhetorics employed in the dispute are described and documented. They are shown to have been associated with divergent conceptions of the membership of the human community and of the moral boundary within which embryo research shoul d be required to operate. Suggestions are offered regarding the cultur al preservation of the critical rhetoric of science, the influence of the two rhetorics upon the legislative outcome of parliamentary debate , and the relevance of these rhetorics to future reappraisals of the l imits of scientific research.
