Relevant to philosophy, law, management, and artificial intelligence, these papers explore the applicability of nonmonotonic or defeasible logic to normative reasoning. The resulting systems purport to solve well-known deontic paradoxes and to provide a better treatment than classical deontic logic does ofprima facieobligation, conditional obligation, and priorities of normative principles. | Defeasible Deontic Logic by Donald Nute, Paperback | Indigo Chapters
