 Traditional approaches to law treat legal rules as normative, i.e., as giving citizens reasons for action. These approaches present two philosophical questions: what is the nature of the reasons for action that law gives? and do individuals have a general obligation to obey the law? The first question is generally understood as asking whether a legal rule provides a moral reason for action. The second question has been extensively examined in the legal and philosophical literature. Murphy [2014] provides a clear perspective on this literature.
