Dissent, polemics and rivalry have always been at the centre of intellectual development. The scholarly Streitkultur was given a fresh impetus by the newly founded universities in the High Middle Ages and later turned into a quintessential part of early modern intellectual life, with the emergence of the Protestant Reformation creating a new momentum. It was not only mirrored in various well-known intellectual disputations and controversies, but also embodied in numerous literary genres and non-literary modes of expression, as well as discursive or political strategies. Moreover, the harsh debates notwithstanding, consensus was also actively searched for, both within particular disciplines and within society as a whole. This volume collects thirteen contributions offering a very rich variety of topics with regard to the negotiation of disagreements from the twelfth till the eighteenth centuries. They reflect inter alia upon the rules and conventions of the intellectual debate, upon the media used to negotiate dissent, as well as upon the role of formal institutions created to judge and decide in cases of dissent. The contributions are offered by scholars from fields as diverse as history of literature, political history, history of philosophy, history of Church and theology, and legal history.
