People may have open minds on whether a life-extending drug or technology is going to be developed before their sixties and may strongly desire that development. Do they therefore hope that it occurs? Do they hope for it in the substantive sense of “pinning their hopes” on the development? No, they do not. Hoping for a prospect in that sense certainly presupposes having an open mind on whether it will occur and having a desire for its occurrence. But, more crucially, (...) it means investing the prospect with a characteristic, galvanizing, and orientating role: it involves setting aside doubts about the possible nonoccurrence of the prospect and acting accordingly. This article offers a characterization of hope in that substantive sense and argues both that it can be rational and that it is ubiquitous. (shrink)

Modal sentences of the form "every F might be G" and "some F must be G" have a threefold ambiguity. in addition to the familiar readings "de dicto" and "de re", there is a third reading on which they are examples of the "plural de re": they attribute a modal property to the F's plurally in a way that cannot in general be reduced to an attribution of modal properties to the individual F's. The plural "de re" readings of modal (...) sentences cannot be captured within standard quantified modal logic. I consider various strategies for extending standard quantified modal logic so as to provide analyses of the readings in question. I argue that the ambiguity in question is associated with the scope of the general term 'F'; and that plural quantifiers can be introduced for purposes of representing the scope of a general term. Moreover, plural quantifiers provide the only fully adequate solution that keeps within the framework of quantified modal logic. (shrink)

In December 2007 it was revealed that the British government is considering the exclusion of certain groups of migrants—those considered to be present “illegally”—from primary health care provided by the National Health Service. At present, practitioners have discretion to accept any individual for NHS treatment regardless of their status. A joint Home Office and Department of Health review is examining this access for foreign nationals, and the likely outcome is the restriction of access to irregular migrants, which would, according to (...) the Institute of Public Policy Research, affect around 390,000 people. In 2004 such groups were excluded from NHS secondary care, most controversially from treatment for HIV, and so the present proposal would bar them from all but emergency health treatment. (shrink)

Arguments aimed at undermining certain accounts of the grounds of political obligations—no matter how successful they may be—fall far short of demonstrating that there are no such obligations. Doubts about the efficacy of these arguments in this latter regard seem even more justified when it is recognized that parallel lines of reasoning can be developed in the area of filial obligations , which arguments provide rather less than conclusive reasons for denying that there are filial obligations .Furthermore, we have good (...) reason to believe that there are political obligations if patriotism is a virtue, and also that patriotism is indeed a virtue. We therefore have a basis on which to affirm the existence of political obligations—a basis whose soundness is independent of the acceptability of particular accounts of the grounds of political obligation. Hence, even if standard accounts of the grounds of political obligations are problematic in certain respects, we should not regard this consideration as capable by itself of establishing that there are no such obligations.

This paper is a critical study of Christians among the Virtues: Theological Conversations with Ancient and Modern Ethics by Stanley Hauerwas and Charles Pinches. It has four parts. First, I consider several possible responses to G. E. M. Anscombe’s famous challenge to modern moral philosophy in order to provide a framework in which the project of Hauerwas and Pinches can be located. Next I criticize their attempt to eliminate the realm of obligation from morality. Then I examine their treatment of (...) Martha Nussbaum’s work onAristotle in order to explore differences between secular and Christian appropriations of Aristotle. Finally, I discuss their views on the virtue of obedience and criticize their arguments against rival Kantian and divine command views. (shrink)

Business ethics is a topic receiving much attention in the literature. However, the term 'business ethics' is not adequately defined. Typical definitions refer to the rightness or wrongness of behavior, but not everyone agrees on what is morally right or wrong, good or bad, ethical or unethical. To complicate the problem, nearly all available definitions exist at highly abstract levels. This article focuses on contemporary definitions of business ethics by business writers and professionals and on possible areas of agreement among (...) the available definitions. Then a definition is synthesized that is broad enough to cover the field of management in a sense as full as most managers might conceive of it. (shrink)

Composition as identity, as I understand it, is a theory of the composite structure of reality. The theory’s underlying logic is irreducibly plural; its fundamental primitive is a generalized identity relation that takes either plural or singular arguments. Strong versions of the theory that incorporate a generalized version of the indiscernibility of identicals are incompatible with the framework of plural logic, and should be rejected. Weak versions of the theory that are based on the idea that composition is merely analogous (...) to identity are too weak to be interesting, lacking in metaphysical consequence. I defend a moderate version according to which composition is a kind of identity, and argue that the difference is metaphysically substantial, not merely terminological. I then consider whether the notion of generalized identity, though fundamental, can be elucidated in modal terms by reverse engineering Hume’s Dictum. Unfortunately, for realists about possible worlds, such as myself,... (shrink)

Shame is a puzzling emotion. On the one hand, to feel ashamed is to feel badly about oneself; but on the other hand, it also seems to be a response to the way the subject is perceived by other people. So whose standards is the subject worried about falling short of, his own or those of an audience? I begin by arguing that it is the audience's standards that matter, and then present a theory of shame according to which shame (...) is a response to the subject's perception that he is not thought of in the way he intrinsically values himself for being thought of by someone else. Then I go on to suggest some refinements to this basic view. First, the subject of shame is primarily concerned about his audience's attitudes toward him, not what they believe about him. And second, there may be one particular attitude which he values himself for inspiring. There is no very perspicuous term for this attitude, so I call it ‘proto-respect’ – the attitude a social animal directs toward those it regards as valuable allies or bad enemies. (shrink)

In this chapter, I evaluate various conceptions of distance. Of the two most prominent, one takes distance relations to be intrinsic, the other extrinsic. I recommend pluralism: different conceptions can peacefully coexist as long as each holds sway over a distinct region of logical space. But when one asks which conception holds sway at the actual world, one conception stands out. It is the conception of distance embodied in differential geometry, what I call the Gaussian conception. On this conception, all (...) fundamental facts about distance are “local” facts.” But there is a problem: the Gaussian conception, notwithstanding its mathematical and physical credentials, appears metaphysically suspicious on Humean grounds. In the final section, I suggest that the Gaussian conception can be given a sound metaphysical footing in terms of non-standard analysis. (shrink)

This paper considers pick-the-winners contests as a simple method for harnessing the wisdom of crowds to produce probability forecasts. Pick-the-winners contests are those in which players pick the outcomes of selected future binary events with a prize going to the player with the most correct picks. In contrast to soliciting probability forecasts from experts, this paper shows that competition among players is to be encouraged because it improves the accuracy of the resulting crowd probability forecasts. This improvement comes because the (...) competition not only discourages the overbetting of favorites that occurs if prizes are awarded based on absolute performance, but also helps mitigate the public knowledge bias that occurs if everyone reports truthfully. In addition to the theoretical arguments, the paper analyzes picks from 6 years of pick-the-winners contests involving hundreds of players and 1037 college lacrosse games to find that the crowd proportions outperformed two benchmark sets of probabilities.

It follows from Humean principles of plenitude, I argue, that island universes are possible: physical reality might have 'absolutely isolated' parts. This makes trouble for Lewis's modal realism; but the realist has a way out. First, accept absolute actuality, which is defensible, I argue, on independent grounds. Second, revise the standard analysis of modality: modal operators are 'plural', not 'individual', quantifiers over possible worlds. This solves the problem of island universes and confers three additional benefits: an 'unqualified' principle of compossibility (...) can be accepted; the possibility of nothing can be accommodated; and the identity of indiscernible worlds can be decisively refuted.

Metaphor has a double life. It can be described as a directional process in which a stable, familiar base domain provides inferential structure to a less clearly specified target. But metaphor is also described as a process of finding commonalities, an inherently symmetric process. In this second view, both concepts may be altered by the metaphorical comparison. Whereas most theories of metaphor capture one of these aspects, we offer a model based on structure-mapping that captures both sides of metaphor processing. (...) This predicts (a) an initial processing stage of symmetric alignment; and (b) a later directional phase in which inferences are projected to the target. To test these claims, we collected comprehensibility judgments for forward (e.g., “A rumor is a virus”) and reversed (“A virus is a rumor”) metaphors at early and late stages of processing, using a deadline procedure. We found an advantage for the forward direction late in processing, but no directional preference early in processing. Implications for metaphor theory are discussed. (shrink)

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

First published in 1990 as the second part of volume 50 of Heidegger’s Complete Works, Introduction to Philosophy presents Heidegger’s final lecture course given at the University of Freiburg in 1944 before he was drafted into the German army. While the lecture is incomplete, Heidegger provides a clear and provocative discussion of the relation between philosophy and poetry by analyzing Nietzsche’s poetry. Here, Heidegger explores themes such as the home and homelessness, the age of technology, globalization, postmodernity, the philosophy of (...) poetry and language, aesthetics, and the role of philosophy in society. Translated into English for the first time, this text will be of particular interest to those who study Heidegger’s politics and political philosophy. (shrink)

According to David Lewis, a realist about possible worlds must hold that actuality is relative: the worlds are ontologically all on a par; the actual and the merely possible differ, not absolutely, but in how they relate to us. Call this 'Lewisian realism'. The alternative, 'Leibnizian realism', holds that actuality is an absolute property that marks a distinction in ontological status. Lewis presents two arguments against Leibnizian realism. First, he argues that the Leibnizian realist cannot account for the contingency of (...) actuality. Second, he argues that the Leibnizian realist cannot explain why skepticism about one's own actuality is absurd. In this paper, I mount a defense of Leibnizian realism. (shrink)

I am a realist of a metaphysical stripe. I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they comprise, (...) metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

This paper seeks to show Kant’s importance for the formal distinction between descriptive natural history and a developmental history of nature that entered natural history discussions in the late eighteenth century. It is argued that he developed this distinction initially upon Buffon’s distinctions of ‘abstract’ and ‘physical’ truths, and applied these initially in his distinction of ‘varieties’ from ‘races’ in anthropology. In the 1770s, Kant appears to have given theoretical preference to the ‘history’ of nature [Naturgeschichte] over ‘description’ of nature (...) [Naturbeschreibung]. Following Kant’s confrontations with Johann Herder and Georg Forster in the late 1780s, Kant weakened the epistemic status of the ‘history of nature’ and gave theoretical preference to ‘description of nature’. As a result, Kant’s successors, such as Goethe, could draw from Kant either a justification for a developmental history of nature, or, as this paper argues, a warrant from the critical philosophy for denying the validity of the developmental history of nature as anything more than a ‘regulative’ idea of reason.

The article explicates a notion of prudence according to which an agent acts prudently if he acts so as to satisfy not only his present preferences, but his past and future preferences as well. A simplified decision-theoretic framework is developed within which three analyses of prudence are presented and compared. That analysis is defended which can best handle cases in which an agent's present act will affect his future preferences.

If realism about possible worlds is to succeed in eliminating primitive modality, it must provide an 'analysis' of possible world: nonmodal criteria for demarcating one world from another. This David Lewis has done. Lewis holds, roughly, that worlds are maximal unified regions of logical space. So far, so good. But what Lewis means by 'unification' is too narrow, I think, in two different ways. First, for Lewis, all worlds are (almost) 'globally' unified: at any world, (almost) every part is directly (...) linked to (almost) every other part. I hold instead that some worlds are 'locally' unified: at some worlds, parts are directly linked only to "neighboring" parts. Second, for Lewis, each world is (analogically) 'spatio-temporally' unified; every world is 'spatio-temporally' isolated from every other. I hold instead: a world may be unified by nonspatio-temporal relations; every world is 'absolutely' isolated from every other. If I am right, Lewis's conception of logical space is impoverished: perfectly respectable worlds are missing. (shrink)

Humeans have a problem with quantities. A core principle of any Humean account of modality is that fundamental entities can freely recombine. But determinate quantities, if fundamental, seem to violate this core principle: determinate quantities belonging to the same determinable necessarily exclude one another. Call this the problem of exclusion. Prominent Humeans have responded in various ways. Wittgenstein, when he resurfaced to philosophy, gave the problem of exclusion as a reason to abandon the logical atomism of the Tractatus with its (...) free recombination of elementary propositions. Armstrong promoted a mereological solution to the problem of exclusion; but his account fails in manifold ways to provide a general solution to the problem. Lewis studiously avoided committing to any one solution, trusting simply that, since Humeanism was true, there had to be some solution. Abandonment; failure; avoidance: we Humeans need to do better. -/- In this paper, I present what I take to be the best account of quantities, tailoring it where needed to meet Humean demands as well as my own prior commitment to quidditism, and my own comparativist inclinations. In short: determinables, not determinates, are the fundamental properties, and freely recombine; determinates arise from the instantiation of determinables in an enhanced world structure; determinate quantities may be local (in a sense to be explained), but they are not intrinsic. Is the account I end up with Humean? Not, unfortunately, as it stands: the problem of exclusion still rears its ugly head. After dismissing a failed attempt at a solution, I consider in the final section the two viable Humean options. One attributes the source of the necessary exclusions to conventional definition, the other attributes it to logic. The first is safe and familiar, but not a response I can accept given my other commitments. The second is more radical and less familiar; but I am convinced it is on the right track. I don’t have space to develop it much here, but I put it out for future research. (shrink)

In this paper I argue that holes are not objects, but should instead be construed as properties or relations. The argument proceeds by first establishing a claim about angles: that angles are not objects, but properties or relations. It is then argued that holes and angles belong to the same category, on the grounds that they share distinctive existence and identity conditions. This provides an argument in favour of categorizing holes as one categorizes angles. I then argue that a commitment (...) to the existence of properties to be identified with holes provides sufficient resources to account for true claims about holes. (shrink)

Which mathematical structures are possible, that is, instantiated by the concrete inhabitants of some possible world? Are there worlds with four-dimensional space? With infinite-dimensional space? Whence comes our knowledge of the possibility of structures? In this paper, I develop and defend a principle of plenitude according to which any mathematically natural generalization of possible structure is itself possible. I motivate the principle pragmatically by way of the role that logical possibility plays in our inquiry into the world.
