Lawmaking is – paradigmatically – a type of speech act: people make law by saying things. It is natural to think, therefore, that the content of the law is determined by what lawmakers communicate. However, what they communicate is sometimes vague and, even when it is clear, the content itself is sometimes vague. This monograph examines the nature and consequences of these two linguistic sources of indeterminacy in the law. The aim is to give plausible answers to three related questions: In virtue of what is the law vague? What might be good about vague law? How should courts resolve cases of vagueness? It argues that vagueness in the law is sometimes a good thing, although its value should not be overestimated. It also proposes a strategy for resolving borderline cases, arguing that textualism and intentionalism – two leading theories of legal interpretation – often complement rather than compete with each other.

Vagueness is a subject of long-standing interest in the philosophy of language, metaphysics, and philosophical logic. Numerous accounts of vagueness have been proposed in the literature but there has been no general consensus on which, if any, should be be accepted. Kit Fine here presents a new theory of vagueness based on the radical hypothesis that vagueness is a "global" rather than a "local" phenomenon. In other words, according to Fine, the vagueness of an object or expression cannot properly be considered except in its relation to other objects or other expressions. He then applies the theory to a variety of topics in logic, metaphysics and epistemology, including the sorites paradox, the problem of personal identity, and the transparency of mental phenomenon. This is the inaugural volume in the Rutgers Lectures in Philosophy series, presenting lectures from the most important contemporary thinkers in the discipline.

Presents a systematic, contemporary defence of the natural law outlook in ethics, politics and jurisprudence.

If you keep removing single grains of sand from a heap, when is it no longer a heap? From discussions of the heap paradox in classical Greece, to modern formal approaches like fuzzy logic, Timothy Williamson traces the history of the problem of vagueness. He argues that standard logic and formal semantics apply even to vague languages and defends the controversial, realist view that vagueness is a form of ignorance - there really is a grain of sand whose removal turns a heap into a non-heap, but we can never know exactly which one it is.

Vagueness is a deeply puzzling aspect of the relation between language and the world. Is it a feature of the way we represent reality in language, or a feature of reality itself? How can we reason with vague concepts? Cuts and Clouds presents the latest work towards an understanding of these puzzles about the nature and logic of vagueness.

This collection brings together the best contemporary philosophical work in the area of intersection between philosophy of language and the law. Some of the contributors are philosophers of language who are interested in applying advances in philosophy of language to legal issues, and some of the participants are philosophers of law who are interested in applying insights and theories from philosophy of language to their work on the nature of law and legal interpretation. By making this body of recent work available in a single volume, readers will gain both a general overview of the various interactions between language and law, and also detailed analyses of particular areas in which this interaction is manifest. The contributions to this volume are grouped under three main general areas: The first area concerns a critical assessment, in light of recent advances in philosophy of language, of the foundational role of language in understanding the nature of law itself. The second main area concerns a number of ways in which an understanding of language can resolve some of the issues prevalent in legal interpretation, such as the various ways in which semantic content can differ from law's assertive content; the contribution of presuppositions and pragmatic implicatures in understanding what the law conveys; the role of vagueness in legal language, for example. The third general topic concerns the role of language in the context of particular legal doctrines and legal solutions to practical problems, such as the legal definitions of inchoate crimes, the legal definition of torture, or the contractual doctrines concerning default rules. Together, these three key issues cover a wide range of philosophical interests in law that can be elucidated by a better understanding of language and linguistic communication.
