The deontic modal must has two surprising properties: an assertion of must p does not permit a denial of p, and must does not take past tense complements. I first consider an explanation of these phenomena that stays within Angelika Kratzer’s semantic framework for modals, and then offer some reasons for rejecting that explanation. I then propose an alternative account, according to which simple must sentences have the force of an imperative.

This article explores the question: what is it for two or more people to intend to do something in the future? In a technical phrase, what is it for people to share an intention ? Extending and refining earlier work of the author’s, it argues for three criteria of adequacy for an account of shared intention (the disjunction, concurrence, and obligation criteria) and offers an account that satisfies them. According to this account, in technical terms explained in the paper, people (...) share an intention when and only when they are jointly committed to intend as a body to do such-and-such in the future. This account is compared and contrasted with the common approach that treats shared intention as a matter of personal intentions, with particular reference to the work of Michael Bratman. (shrink)

De Cive (On the Citizen) is the first full exposition of the political thought of Thomas Hobbes, the greatest English political philosopher of all time. Professors Tuck and Silverthorne have undertaken the first complete translation since 1651, a rendition long thought (in error) to be at least sanctioned by Hobbes himself. On the Citizen is written in a clear, straightforward, expository style, and in many ways offers students a more digestible account of Hobbes's political thought than the Leviathan itself. This (...) new translation is both accurate and accessible, and is itself a significant scholarly event: it is accompanied by a full glossary of Latin terms, a chronology, bibliography, and an expository introduction. Throughout the editors have emphasised consistency in the translation and usage of Hobbes's basic conceptual vocabulary, respecting Hobbes's own concern for accurate definition of terms. (shrink)

Imperatives may be interpreted with many subvarieties of directive force, for example as orders, invitations, or pieces of advice. I argue that the range of meanings that imperatives can convey should be identified with the variety of interpretations that are possible for non-dynamic root modals (what I call ‘priority modals’), including deontic, bouletic, and teleological readings. This paper presents an analysis of the relationship between imperatives and priority modals in discourse which asserts that, just as declaratives contribute to the Common (...) Ground and thus provide information relevant to the interpretation of epistemic modals in subsequent discourse, imperatives contribute to another component of the discourse context, the addressee’s To-Do List, which serves as a contextual resource for the interpretation of priority modals. This analysis predicts that the interpretation of imperatives and modals in discourse is constrained in surprising ways; these predictions are borne out. (shrink)

Hong Oak Yun is a person who is over three inches tall. And now you know who Hong Oak Yun is. For if someone were to ask you ‘Who is Hong Oak Yun?’, you could answer that Hong Oak Yun is a person who is over three inches tall, and you would know what you were saying. So you know an answer to the question ‘Who is Hong Oak Yun?’, and that is sufficient for knowing who Hong Oak Yun is. (...) Getting to know who a person is may be easier than you think. (shrink)

W. Labov's & T. Labov's findings concerning their child grammar acquisition ("Learning the Syntax of Questions" in Recent Advances in the Psychology of Language, Campbell, R. & Smith, P.

Much of our know-how is acquired through practice: we learn how to cook by cooking, how to write by writing, and how to dance by dancing. As Aristotle argues, however, this kind of learning is puzzling, since engaging in it seems to require possession of the very knowledge one seeks to obtain. After showing how a version of the puzzle arises from a set of attractive principles, I argue that the best solution is to hold that knowledge-how comes in degrees, (...) and through practice a person gradually learns how to do something. However, the two standard accounts of know-how in the literature, intellectualism and anti-intellectualism, cannot properly account for the distinctive way in which know-how is gradually acquired by practice, a process in which conceptual representations and practical abilities are intimately interwoven. Drawing on Gareth Evans's work, I outline an account that may do so, and use this account to distinguish between two forms of learning to explain why skill generally cannot be learnt through testimony, and requires practice.

Some arguments include imperative clauses. For example: ‘Buy me a drink; you can’t buy me that drink unless you go to the bar; so, go to the bar!’ How should we build a logic that predicts which of these arguments are good? Because imperatives aren’t truth apt and so don’t stand in relations of truth preservation, this technical question gives rise to a foundational one: What would be the subject matter of this logic? I argue that declaratives are used to (...) produce beliefs, imperatives are used to produce intentions, and beliefs and intentions are subject to rational requirements. An argument will strike us as valid when anyone whose mental state satisfies the premises is rationally required to satisfy the conclusion. For example, the above argument reflects the principle that it is irrational not to intend what one takes to be the necessary means to one’s intended ends. I argue that all intuitively good patterns of imperative inference can be explained using off-the-shelf formulations of our rational requirements. I then develop a formal-semantic theory embodying this view that predicts a range of data, including free-choice effects and Ross’s paradox. The resulting theory shows one way that our aspirations to rational agency can be discerned in the patterns of our speech, and is a case study in how the philosophy of language and the philosophy of action can be mutually illuminating.

This paper argues that promises are proposals in joint practical deliberation, the activity of deciding together what to do. More precisely: to promise to ϕ is to propose (in a particular way) to decide together with your addressee(s) that you will ϕ. I defend this deliberative theory by showing that the activity of joint practical deliberation naturally gives rise to a speech act with exactly the same properties as promises. A certain kind of proposal to make a joint decision regarding (...) one's own actions turns out to have the very same normative effects, under the very same conditions, as a promise. I submit that this cannot be a coincidence: we should conclude that promises and the relevant kind of proposals in joint practical deliberation are one and the same. (shrink)

We often rely on others for guidance about what to do. But wouldn't it be better to rely instead on only your own solo judgment? Deferring to others about moral matters, after all, can seem to conflict what Enlightenment demands. In Guided by Voices, however, Eric Wiland argues that there is nothing especially bad about relying on others in forming your moral views. You may rely on others for forming your moral views, just as you can your views about anything (...) else. You can accept moral testimony without loss. Furthermore, there are several distinctive social goods attainable by being guided by what others say. Thus, it can be better to be guided by moral testimony than by your own moral lights. Wiland also argues that relying on others for moral advice has one advantage over relying on others for moral testimony. For when you trust your adviser's advice, you both thereby form a joint agent that can achieve autonomy, moral understanding, and morally worthy action. Sometimes taking another's advice is your only way to act well. Arguing against the presumption that moral reasoning is ideally done alone, Guided by Voices is the first book to significantly address both moral testimony and advice. (shrink)

Why is it useful to talk and think about knowledge-how? Using Edward Craig’s discussion of the function of the concepts of knowledge and knowledge-how as a jumping off point, this paper argues that considering this question can offer us new angles on the debate about knowledge-how. We consider two candidate functions for the concept of knowledge-how: pooling capacities, and mutual reliance. Craig makes the case for pooling capacities, which connects knowledge-how to our need to pool practical capacities. I argue that (...) the evidence is much more equivocal. My suggested diagnosis is that the concept of knowledge-how plays both functions, meaning that the concept of knowledge-how is inconsistent, and that the debate about knowledge-how is at least partly a metalinguistic negotiation. In closing, I suggest a way to revise the philosophical concept of knowledge how. (shrink)

A framework for pragmatic analysis is proposed which treats discourse as a game, with context as a scoreboard organized around the questions under discussion by the interlocutors. The framework is intended to be coordinated with a dynamic compositional semantics. Accordingly, the context of utterance is modeled as a tuple of different types of information, and the questions therein — modeled, as is usual in formal semantics, as alternative sets of propositions — constrain the felicitous flow of discourse. A requirement of (...) Relevance is satisfied by an utterance (whether an assertion, a question or a suggestion) iff it addresses the question under discussion. Finally, it is argued that the prosodic focus of an utterance canonically serves to reflect the question under discussion (at least in English), placing additional constraints on felicity in context.

The standard philosophical project of analysing the concept of knowledge has radical defects in its arbitrary restriction of the subject matter, and its risky theoretical presuppositions. Edward Craig suggests a more illuminating approach, akin to the `state of nature' method found in political theory, which builds up the concept from a hypothesis about the social function of knowledge and the needs it fulfils. Light is thrown on much that philosophers have written about knowledge, about its analysis and the obstacles to (...) its analysis, and on the debate over scepticism. It becomes apparent why many languages not only have such constructions as `knows whether' and `knows that', but also have equivalents of `knows how to' and `know' followed by a direct object. Thus the inquiry is both broadened in scope and made theoretically less fragile. (shrink)

First published in 1962, contains the William James Lectures delivered at Harvard University in 1955. It sets out Austin's conclusions in the field to which he directed his main efforts for at least the last ten years of his life. Starting from an exhaustive examination of his already well- known distinction of performative utterances from statements, Austin here finally abandons that distinction, replacing it by a more general theory of 'illocutionary forces' of utterances which has important bearings on a wide (...) variety of philosophical problems.

How can you give your interlocutor a reason to act? One way is by manipulating his deliberative context through threats, flattery, or other incentives. Another is by addressing him in the way distinctive of reasoning with him. I aim to account for the possibility of this non-manipulative form of address by showing how it is realized through the performance of a specific illocutionary act, that of advising as inviting to trust. I argue that exercise of a capacity for reasonable trust (...) can give us reasons that are not grounded in our motivational susceptibilities. Here I echo Kant on moral motivation. But this rational faculty assesses not principles but persons. Here I echo Hume on the moral virtues. We can thus agree with Kant about the motivational efficacy of practical reasons dispensed through advice but agree with Hume about the form of intelligence needed to put ourselves in touch with them.

This paper launches a new criticism of Michael Smith’s advice model of internalism. Whereas Robert Neal Johnson argues that Smith’s advice model collapses into the example model of internalism, the author contends that taking advice seriously pushes us instead toward some version of externalism. The advice model of internalism misportrays the logic of accepting advice. Agents do not have epistemic access to what their fully rational selves would advise them to do, and so it is necessary for a model of (...) practical reason based upon advice to reflect the fact that agents take advice only from other people. This fact mayor may not support internalism. Whether it does depends upon the content of the good adviser’s advice, something we cannot know unless we ourselves are fully rational. We see in a new way, then, how the internalism/externalism debate depends upon the content of practical reason. (shrink)

Is there a mode of sincere advice in which the standards of the adviser are put aside in favor of the standards of the advisee? I consider two sorts of cases that appear to be such that the adviser is evaluating things from within the advisee’s system of standards even though this system conflicts with her own; and I argue that these cases are best interpreted in ways that dissolve this appearance. I then argue that the nature of sincere advice (...) precludes an adviser’s putting aside her own system of standards in favor of a competing system of standards. It follows that, contrary to what some have suggested, it cannot be that practical reason judgments—which are concerned with what an agent has reason to do or not to do and which can figure as advice— evaluate actions from within the agent’s (as opposed to the judger’s) system of standards.

Recently, philosophers have employed the notion of advice to tackle a variety of philosophical problems. In particular, Michael Smith and Nomy Arpaly have in different ways related the notion of advice to the notion of a reason for action. Here I argue that both accounts are flawed, because each operates with a simplistic picture of the way advice works. I conclude that it would be wise to take more time to analyze what advice is and how it in fact works, (...) before putting it to particular philosophical uses. (shrink)
