“Assessing Pollock's systems of logic-based argumentation with suppositions”
Abstract: We present and evaluate a largely unexplored line of John Pollock's work: his account of logic-based argumentation with suppositions. Via the inclusion of suppositional arguments, Pollock was able to represent a large additional class of important patterns of defeasible reasoning, such as conditionalization and reasoning by cases. The result is a formal system that exceeds the expressive power of most present-day accounts of logic-based argumentation. In our discussion of Pollock's system, we focus on a couple of general design choices that are particularly relevant for philosophical accounts of suppositional reasoning, and we highlight the problems caused by some of these choices.
