The essays that are collected in Controversy and Confrontation provide a closer insight into the relationship between controversy and confrontation that deepens our understanding of the functioning of argumentative discourse in managing differences of opinion. Their authors stem from two backgrounds. First, the controversy scholars Dascal, Marras, Euli, Regner, Ferreira, and Lessl discuss historical controversies in science, both from a theoretical and an empirical perspective; Saim concentrates on a historical controversy; Fritz provides a historical perspective on controversies by analyzing communication principles. Second the argumentation scholars Johnson, van Laar, van Eemeren, Garssen and Meuffels address theoretical or empirical aspects of argumentative confrontation; Aakhus and Vasilyeva examine argumentative discourse from the perspective of conversation analysis; Jackson analyzes argumentative confrontation in a recent debate between scientists and politicians. Last but not least, two contributors, Kutrovátz and Zemplén, make an attempt to bridge the study of historical controversy and the study of argumentation.
