Abstract

In this article we propose contextual deontic logic. Contextual obligations are written as O(ffjfinfl), and are to be read as `ff should be the case if fi is the case, unless fl is the case'. The unless clause is analogous to the justification in Reiter's default rules. We show how contextual obligations can be used to solve certain aspects of contrary-to-duty paradoxes of dyadic deontic logic.
