RHETORIC AND INCOMMENSURABILITY examines the complex relationships among rhetoric, philosophy, and science as they converge on the question of incommensurability, the notion jointly (though not collaboratively) introduced to science studies in 1962 by Thomas Kuhn and Paul Feyerabend. The incommensurability thesis represents the most profound problem facing argumentation and dialogue-in science, surely, but in any symbolic encounter, any attempt to cooperate, find common ground, get along, make better knowledge, and build better societies. This volume brings rhetoric, the chief discipline that studies argumentation and dialogue, to bear on that problem, finding it much more tractable than have most philosophical accounts. The introduction charts the many variations of incommensurability in scholarly literatures, anchoring them in Kuhn's and Feyerabend's work; probes the implications of seeing incommensurability as a rhetorical phenomenon; and introduces the ten chapters from prominent scholars in the rhetoric, history, and philosophy of science, including Paul Hoyningen-Huene, Alan G. Gross, Thomas M. Lessl, Herbert W. Simons, Leah Ceccarelli, Lawrence J. Prelli, John Angus Campbell, Jeanne Fahnestock, Charles Bazerman, René Agustín De los Santos, and Carolyn R. Miller.
