Argues for a "cognitivist" account of the instrumental principle, on which it is the application of theoretical reason to the beliefs that figure in our intentions. This doctrine is put to work in solving a puzzle about instrumental reason that plagues alternative views.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

In this paper I offer an account of the meaning of must and can within the framework of possible worlds semantics. The paper consists of two parts: the first argues for a relative concept of modality underlying modal words like must and can in natural language. I give preliminary definitions of the meaning of these words which are formulated in terms of logical consequence and compatibility, respectively. The second part discusses one kind of insufficiency in the meaning definitions given in (...) the first part, which arise from the ex falso quodlibet paradox of logical consequence. In stepwise fashion, I make an attempt to avoid most of the consequences of this paradox for the meaning definitions of must and can. (shrink)

In this paper, I discuss the distribution and interpretation of free choice items (FCIs) in Greek, a language exhibiting a lexical paradigm of such items distinct from that of negative polarity items. Greek differs in this respect from English, which uniformly employs any. FCIs are grammatical only in certain contexts that can be characterized as nonveridical (Giannakidou 1998, 1999), and although they yield universal-like interpretations in certain structures, they are not, I argue, universal quantifiers. Evidence will be provided that FCIsare (...) indefinites; the quasi-universal effect is shown to be the result of binding by an operator with universal force. Additionally, the limited distribution of FCIs in non veridical contexts can be accounted for by analyzing them as indefinites which must always be interpreted in an intensional type. The difference between ``regular'' indefinites and FCIs, therefore, is reduced to a type difference which captures the fact that only the latter exhibit limited distribution: because of their intensional type, FCIs will be grammatical only in contexts providing alternatives (worlds or situations), and nonveridical contexts do exactly this. By contrast, FCIs are excluded from veridical and episodic contexts because these provide no alternatives and hence do not satisfy the lexical semantic requirement ofFCIs. The proposed analysis is supported by data from other languages as well (Spanish, Catalan,French) and has important consequences regarding the analysis of English any. If FCIs are not universal quantifiers but indefinites, then the usual ambiguity thesis (free choice any being universal, negative polarity any an existential) can no longer be maintained, at least not as one in terms of quantificational force.

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

Accounts of ability in the philosophical literature have tended to be modal ones: claims about an agent’s abilities are understood in terms of what she does in certain non-actual scenarios. In contrast, a prominent account of ability ascriptions in the recent semantics literature appeals to genericity: claims about an agent’s abilities are understood in terms of what she generally manages to do. The latter account resolves some long-standing problems for modal accounts, but encounters problems of its own. I propose a (...) hybrid view, on which ability involves both a modal and a generic element. (shrink)

This essay challenges the widely accepted principle that a person is morally responsible for what he has done only if he could have done otherwise. The author considers situations in which there are sufficient conditions for a certain choice or action to be performed by someone, So that it is impossible for the person to choose or to do otherwise, But in which these conditions do not in any way bring it about that the person chooses or acts as he (...) does. In such situations the person may well be morally responsible for what he chooses or does despite his inability to choose or to do otherwise. Finally the author considers certain suggestions for revising the principle he rejects or for replacing it with a principle of an altogether different kind. (shrink)

An object's disposition to A in circumstances C is masked if circumstances C obtain without the object Aing. This paper explores an analogous sense in which abilities can be masked, and it uses the results of this exploration to motivate an analysis of agents' abilities in terms of dispositions. This analysis is then shown to provide the resources to defend a version of the Principle of Alternate Possibilities against Frankfurt-style counterexamples. Although this principle is often taken to be congenial to (...) incompatibilism concerning free action and determinism, the paper concludes by using the dispositional analysis of abilities to argue for compatibilism, and to show why the 'master argument' for incompatibilism is unsound.

We consider a range of cases—both hypothetical and actual—in which agents apparently know how to \ but fail to believe that the way in which they in fact \ is a way for them to \. These “no-belief” cases present a prima facie problem for Intellectualism about knowledge-how. The problem is this: if knowledge-that entails belief, and if knowing how to \ just is knowing that some w is a way for one to \, then an agent cannot both know (...) how to \ and fail to believe that w, the way that she \s, is a way for her to \. We discuss a variety of ways in which Intellectualists might respond to this challenge and argue that, ultimately, this debate converges with another, seemingly distinct debate in contemporary epistemology: how to attribute belief in cases of conflict between an agent’s avowals and her behavior. No-belief cases, we argue, reveal how Intellectualism depends on the plausibility of positing something like “implicit beliefs”—which conflict with an agent’s avowed beliefs—in many cases of apparent knowledge-how. While there may be good reason to posit implicit beliefs elsewhere, we suggest that there are at least some grounds for thinking that these reasons fail to carry over to no-belief cases, thus applying new pressure to Intellectualism.

Attempts to give necessary and sufficient conditions for demarcating ‘dispositional’ predicates (such as ‘is fragile’) from other predicates are generally acknowledged to fail. This leaves unresolved the question of what it is about paradigm instances of dispositional predicates in virtue of which their application to an object constitutes a disposition ascription. This essay proposes that dispositional predicates are generally derived from ergative verbs, those verbs that allow for certain entailments from transitive to intransitive forms (as ‘Sam broke the glass’ entails (...) ‘The glass broke’). The connection between disposition ascriptions and ergativity is shown to have consequences for the metaphysics of dispositions. (shrink)

Building on the strengths of the first edition, the second edition of the Irwin Nicomachean Ethics features a revised translation (with little editorial intervention), expanded notes (including a summary of the argument of each chapter), an expanded Introduction, and a revised glossary.

Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. I propose an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility — a fragile vase, for instance, is one that can break easily. The view is (...) expounded in some detail and defended against the major objections. (shrink)

We discuss the semantic significance of a puzzle concerning ‘ought’ and conditionals recently discussed by Kolodny and MacFarlane. We argue that the puzzle is problematic for the standard Kratzer-style analysis of modality. In Kratzer’s semantics, modals are evaluated relative to a pair of conversational backgrounds. We show that there is no sensible way of assigning values to these conversational backgrounds so as to derive all of the intuitions in Kolodny and MacFarlane’s case. We show that the appropriate verdicts can be (...) derived by extending Kratzer’s framework to feature a third conversational background and claiming that the relevant reading of ‘ought’ is sensitive to this parameter.

Metaphysicians of modality are increasingly critical of possible-worlds talk, and increasingly happy to accept irreducibly modal properties – and in particular, irreducible dispositions – in nature. The aim of this paper is to provide the beginnings of a modal semantics which uses, instead of possible-worlds talk, the resources of such an 'anti-Humean' metaphysics. One central challenge to an anti-Humean view is the context-sensitivity of modal language. I show how that challenge can be met and a systematic modal semantics provided, given (...) an independently plausible metaphysics of dispositional properties or potentialities. (shrink)

A dynamic semantics for epistemically modalized sentences is an attractive alternative to the orthodox view that our best theory of meaning ascribes to such sentences truth-conditions relative to what is known. This essay demonstrates that a dynamic theory about might and must offers elegant explanations of a range of puzzling observations about epistemic modals. The first part of the story offers a unifying treatment of disputes about epistemic modality and disputes about matters of fact while at the same time avoiding (...) the complexities of alternative theories. The second part of the story extends the basic framework to cover some complicated data about retraction and the interaction between epistemic modality and tense. A comparison between the suggestion made in this essay and current versions of the orthodoxy is provided. (shrink)

We investigate a basic probabilistic dynamic semantics for a fragment containing conditionals, probability operators, modals, and attitude verbs, with the aim of shedding light on the prospects for adding probabilistic structure to models of the conversational common ground.

I motivate and characterize an intensional semantics for ‘ought’ on which it does not behave as a universal quantifier over possibilities. My motivational argument centers on taking at face value some standard challenges to the quantificational semantics, especially to the idea that ‘ought’-sentences satisfy the principle of Inheritance. I argue that standard pragmatic approaches to these puzzles are either not sufficiently detailed or unconvincing.

Abstract In this paper, we show that Greek distinguishes empirically ability as a precondition for action, and ability as initiating and sustaining force for action. In this latter case, the ability verb behaves like an action verb, and the sentence has the logical form of a causative structure φ CAUSE [BECOME ψ] (Dowty 1979). The distinction between ability as potential for action and ability as action itself has a venerable tradition that goes back to Aristotle, and is recently implied in (...) a number of analyses (Mari and Martin 2007, 2009, Thomason 2005). We show first that the phenomenon is not just aspectual ( pace Bhatt 1999, Hacquard 2006, 2009, Pinon 2003): actualized ability emerges with the ability verb also with imperfective aspect and present tense. They key, we argue is causation, which triggers a shift from pure ability, to ability as force (in the sense of Copley and Harley 2010, i.e. as action initiating energy). In Greek, the action reading of the ability modal comes about in an apparent co-ordinate causative structure, where the two clauses are connected with conjunction ke ‘and’— a pattern that we find also in other languages, including English, at least with some action verbs such as try, allow . Our analysis implies a meaning of ability richer than mere possibility ( pace Hacquard); and, by capitalizing on the causative meaning and the presence of force in causative structures, our analysis enables a principled explanation of the shift to action-ability without positing ambiguity for the ability verb ( pace Bhatt 1999).

A number of philosophical projects require a proper understanding of the modal aspects of agency, or of what I call ‘the agentive modalities.’ I propose a general account of the agentive modalities, one which takes as its primitive the decision-theoretic notion of an option. I relate this account to the standard semantics for ‘can’ and to the viability of some positions in the free will debates.

Oxford Philosophical Texts Series Editor: John Cottingham The Oxford Philosophical Texts series consists of authoritative teaching editions of canonical texts in the history of philosophy from the ancient world down to modern times. Each volume provides a clear, well laid out text together with a comprehensive introduction by a leading specialist, giving the student detailed critical guidance on the intellectual context of the work and the structure and philosophical importance of the main arguments. Endnotes are supplied which provide further commentary (...) on the arguments and explain unfamiliar references and terminology, and a full bibliography and index are also included. The series aims to build up a definitive corpus of key texts in the Western philosophical tradition, which will form a reliable and enduring resource for students and teachers alike. David Hume's aim in writing An Enquiry concerning Human Understanding was to introduce his philosophy to a European culture in which many educated people read original works of philosophy. He gives an elegant and accessible presentation of strikingly original and challenging views about the limited powers of human understanding, the attractions of scepticism, the compatibility of free will and determinism, and weaknesses in the foundations of religion. Hume's philosophy was highly controversial in the eighteenth century and remains so today. The text printed in this edition is that of the Clarendon critical edition of Hume's works. A substantial introduction by the editor explains the intellectual background to the work and surveys its main themes. The volume also includes detailed explanatory notes on the text, a glossary of terms, a full list of references, and a section of supplementary readings. (shrink)

In Spanish (and other Romance languages) certain predicates select the subjunctive mood in the embedded clause, while others select the indicative mood. In this paper, I present a new analysis for the predicates that select the subjunctive mood in Spanish that is based on a semantics of comparison. The main generalization proposed here is the following: in Spanish, a predicate selects the subjunctive mood in its embedded proposition if the proposition is compared to its contextual alternatives on a scale introduced (...) by the predicate. In this proposal, predicates that select the subjunctive mood are thus analyzed as gradable predicates. Furthermore, the subjunctive mood morpheme is claimed to make a semantic contribution, namely to evaluate the contextual alternatives that are compared by the predicate. In comparing this proposal to other approaches, I show that it can more straightforwardly account for a number of properties of these predicates (entailment relations, practical inferences, and contexts with more than two alternatives). New empirical evidence for two crucial properties of the predicates that select the subjunctive mood is provided: these predicates are focus sensitive and they are gradable, two properties that follow directly from the proposal developed here. In the vast literature on mood, the link between the appearance of the subjunctive mood and these important properties has never been made before. (shrink)

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.
