Deontic logics for prioritized imperatives.

When a conflict of duties arises,a resolution is often sougth by use of an ordering of priority or importance.This paper examines how such a conflict resolution works,compares mechanisms that have been proposed in the literature,and gives prefernce to one developed by Brewka and Nabel.I distinguish between two cases-that some conflicts may remain unresolved,and that a priority ordering can be determined that resolves all-and provide semantics and exiomatic systems for accordingly defined dyadic deontic operators.
