  abstract = {Deontic logic, the logic of obligations and permissions, is plagued by several paradoxes that have to be understood before deontic logic can be used as a knowledge representation language. In this paper we extend the temporal analysis of Chisholm's paradox using a deontic logic that combines temporal and preferential notions.},
