 Legal philosophers have tried to explain the normativity of law—the fact that the law of a community is, or presents itself as, a guide to the conduct of members of a community. One easy way to express this abstract feature of law is by pointing out that the law can be stated by making normative statements (i.e. statements that use expressions like ‘obligation’, ‘right’, ‘must’, ‘may’). And one attractive way of trying to explain the normativity of law is by explaining the meaning and use of the normative language that is often used in stating the law. That is, the problem of explaining the nature of legal norms (obligations, rights, etc.) can be addressed by explaining the meaning or the use of the normative words that are used in law (‘obligation’, ‘right’,…). Joseph Raz has put it that ‘The problem of the normativity of law is the problem of explaining the use of normative language in describing the law or legal situations.’ (1990, 170)
