Law and Language

The use of language is crucial to any legal system, not only in the same way that it is crucial to politics in general, but also in two special respects. Lawmakers characteristically use language to make law, and law must provide for the authoritative resolution of disputes over the effects of that use of language. Political philosophers are not generally preoccupied with questions in the philosophy of language. But legal philosophers are political philosophers with a specialization that gives language (and philosophy of language) a special importance. [1]

Philosophy of law can gain from a good philosophical account of the meaning and use of language, and from a good philosophical account of the institutionalized resolution of disputes over language. Philosophy of language can gain from studying the stress-testing of language in legal regulation and dispute resolution. And philosophers of language can gain from the reminder that their task is not only to account for what people share in virtue of the mastery of a language; they also need to account for the possibility of disagreements over the meaning and use of language, and for the possibility that there might be good reason for resolving those disagreements in one way rather than another.

After a brief historical note on the linguistic preoccupations of legal philosophers in section 1, section 2 outlines the relation between the law of a jurisdiction and the language with which law can be made and in which it can be expressed. Section 3 surveys philosophical work on the nature of law that rejects a preconception that you can find in this introduction and in sections 1 and 2: that law can be made by the use of language. Section 4 addresses the implications for legal philosophy of the widespread use of evaluative language in law, and section 5 addresses the implications for legal philosophy of the widespread use of vague language in law. Section 6 concludes with an assessment of philosophers’ efforts to use insights from the philosophy of language to address problems of the nature of law.
