Technical Report Number
This technical report consists of three chapters from a larger manuscript that was a finalist in the 1988 Journal of Philosophy Johnsonian competition. These three chapters together represent a revised version of a paper that has been circulating under the title "Defeat Among Arguments II" since January 1988. "Defeat Among Arguments" updates my Computational Intelligence paper of 1987, which represented a novel way of formalizing defeasible reasoning, based on resolving competing arguments. "The Yale Shooting Problem" updates my Cognitive Science paper of 1987, and attempts a rebuttal of Hanks and McDermott's evaluation in their 1987 Artificial Intelligence paper. The last section, "Conventionalism and Non-Monotonicity," is a brief consideration of Touretzky, Thomason, and Horty's "Clash of Intuitions," and the prospects for choosing among languages for representing defeasible knowledge.
