Book excerpt: Rhetoric, as a general teaching -- while preaching locality of action and guidelines for handling that locality -- has tended from the beginning to serve as a universality. It has offered a generalized techne with only limited categories, appropriate for all discursive situations, at least for those that were not excluded from the realm of rhetoric. Nonetheless, from its beginnings, rhetoric limited its interests to certain activity fields such as law, government, religion, and most important, the educators of leaders in these activity fields. This collection presents landmarks showing where the Writing-Across-the-Curriculum (WAC) and Writing in the Disciplines (WID) movements have gone. They have opened up a number of prospects that were impossible to see when rhetoric and composition confined their gaze to relatively few discursive activities. This suggests that the rhetorical landscape is becoming more complex and interesting, as well as more responsive to life in the complex, differentiated societies that have emerged in the last few centuries. This volume will reveal to scholars and researchers a range of possibilities for the study of disciplinary discourse and its teaching, and suggest to them new prospects for the future -- and for the better.
