Sample chapter from H. Asgeirsson, The Nature and Value of Vagueness in the Law (Hart Publishing, 2020), in which I present and partially defend a version of what has come to be called the communicative-content theory of law. Book abstract: 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. The monograph examines the nature and consequences of these two linguistic sources of indeterminacy in the law with the aim of providing 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? (shrink)

It is natural to think that law ought not to be vague. After all, law is supposed to guide conduct, and vague law seems poorly suited to do that. Contrary to this common impression, however, a number of authors have argued that vagueness in the law is sometimes a good thing, because it is a means to achieving certain valuable legislative ends. In this article, I argue that many authors—including Timothy Endicott and Jeremy Waldron—wrongly associate vagueness with instrumental roles that (...) are really played by a closely related semantic phenomenon.

The first part of the chapter surveys some of the main ways in which the Sorites Paradox has figured in arguments in practical philosophy in recent decades, with special attention to arguments where the paradox is used as a basis for criticism. Not coincidentally, the relevant arguments all involve the transitivity of value in some way. The second part of the chapter is more probative, focusing on two main themes. First, I further address the relationship between the Sorites Paradox and (...) the main arguments discussed in the first part, by elucidating in what sense they rely on (something like) tolerance principles. Second, I briefly discuss the prospect of rejecting the respective principles, aiming to show that we can do so for some of the arguments but not for others. The reason is that in the latter cases the principles do not function as independent premises in the reasoning but, rather, follow from certain fundamental features of the relevant scenarios. I also argue that not even adopting what is arguably the most radical way to block the Sorites Paradox – that of weakening the consequence relation – suffices to invalidate these arguments. (shrink)

Roy Sorensen has argued that vagueness in the law cannot be justified by appeal to the value of power-delegation, and thereby threatens to take away one of the main reasons for thinking that vagueness can be valuable to law. Delegation of power to officials is justified, he thinks, only if these officials are in a better position to discover whether a particular x is F, a condition not satisfied in cases of vagueness. I argue that Sorensen’s argument is unsound: delegation (...) of power can be valuable even if the delegates are not in a better position to answer that question. (shrink)

The following two theses seem both plausible and consistent: in cases where it is indeterminate whether the relevant legal language applies to the relevant set of facts, officials are not bound to decide the case one way rather than the other, but may reason either way; all reasons for action are—in some relevant sense—knowable. In this paper, I point out what I take to be a robust but unacknowledged tension between these two claims. The tension requires some careful teasing out, (...) but the basic idea is that given certain further plausible assumptions concerning law, language, and normativity, the two claims turn out to be inconsistent. In addition to examining the sources of the tension in some detail, I also address several possible objections to my argument and discuss which of the many theses should be rejected. (shrink)

In "The Value of Vagueness," Timothy Endicott argues that vague law can be better than precise law. I think he is in many respects correct, but will suggest that we modify and supplement his framework in order to get a firmer grip on what I call the Lawmakers' Challenge: the scenario in which lawmakers find themselves when they must determine whether the consequences of precision are worse than the consequences of vagueness. This will allow us to identify several points of (...) actual and possible disagreement regarding the value of vagueness for law, each of which could affect Endicott's claim that vagueness is sometimes preferable to precision. The framework will also allow us to compare positions that seem - on the face of it - hard to compare, due to the fact that they rest on different theories of value and/or different theories of law.
