I show that resolution-oriented discourse has a distinctive normative structure, partially subject to theoretical explication.Those with a keen commitment to the idea of working out differences of opinion dialogically may fail to grasp what such a commitment entails. In the heat of discursive conflict, discerning our obligations is often difficult. These difficulties yield a general lack of clarity concerning the norms in question. Yet theory can inform reason-giving practice by clarifying the normative structures underlying such discourse. A logic of disputation must be anchored in the relevant features of concrete discursive contexts, even as it abstracts from their particularities. Different types of challenge present claimants with different options for redeeming the claim challenged, and defending moves, too, open up and close off various options for the challenger. I show that the structure of the normative "field" at any point in the dialectic can be characterized with surprising precision.
