Individuals who become ill as a result of personal lifestyle choices often shift the monetary costs of their healthcare needs to the taxpaying public or to fellow members of a private insurance pool. Some argue that policies permitting such cost shifting are unfair. Arguments for this view may seem to draw support from luck egalitarian accounts of distributive justice. This essay argues that the luck egalitarian framework provides no such support. To allocate healthcare costs on the basis of personal responsibility (...) would arbitrarily and publicly burden socially detectable risk-takers while undetectable risk-takers continue to get a free ride. That problem is unavoidable even on the assumption that distributive institutions outside the healthcare sector are fully just. In actual, farfrom-just societies, imposing personal liability for the costs of voluntary risk taking would be wrong for an additional reason. Doing so would tend to magnify existing distributive injustices. These conclusions draw attention to two common ‘moral fallacies of the second best’ that can arise when applying ideal normative theory to matters of institutional design and in real-world policy contexts.

International borders concentrate opportunities in some societies while limiting them in others. Borders also prevent those in the less favored societies from gaining access to opportunities available in the more favored ones. Both distributive effects of borders are treated here within a comprehensive framework. I argue that each state should have broad discretion under international law to grant or deny entry to immigration seekers; but more favored countries that find themselves under immigration pressure should be legally obligated to fund development (...) assistance for countries that generate immigration pressure. Funding should be subject to conditions of fair and effective use in recipient countries, and should aim at a near-term target of immigration-pressure equilibrium. Equilibrium obtains between two countries when, given appropriate background circumstances, the same proportion of individuals in each manifests a preference to migrate to the other. If meeting the equilibrium target in the short term would be to the long-term disadvantage of the worst-off countries, then a Pareto-superior alternative target supersedes. It mandates development assistance at the level that yields the most favorable human development projections for the worstoff countries. An implementable set of institutions is described that can achieve the equilibrium goal in the long term without unduly sacrificing other important ends, including economic growth, political stability, cultural integrity, the political autonomy of distinct societies, and their proper accountability for policy choices. Key Words: global justice • immigration • borders • development • distributive justice • development assistance • equality • international law • cosmopolitanism. (shrink)

Wealth and income are highly predictive of health and longevity. Egalitarians who maintain that this “socioeconomic-status gradient” in health is unjust are challenged by the fact that a significant component of it is owed to the higher prevalence of certain kinds of voluntary risk-taking among members of lower socioeconomic groups. Some egalitarians have argued that these apparently free personal choices are not genuinely free, and that those who make them should not be held morally responsible for the resulting harms to (...) their health. I argue to the contrary that such choices usually are fully free, and that those who make them are responsible for their consequences. This does not imply, however, that society cannot also be responsible for those consequences. It is responsible for them if they are statistically foreseeable and avoidable outcomes of unjust public institutions and policies. I show that many of the harms to health that contribute to the voluntary behavioral component of the SES health gradient satisfy that description. Society can therefore be morally responsible for those harms, even though the individuals who suffer them are also fully responsible for them. (shrink)

According to the popular-choice theory of secession, the inhabitants of any territory, as a group, should have an internationally recognized right to secede from a sovereign state if their majority chooses by referendum to do so, and if they are capable of sustaining legitimate state institutions. Prior efforts to defend this group right on individualistic grounds—such as the individual right to associate freely or to participate as an equal in democratic decision-making—have failed. As a result, some recent defenders of the (...) choice theory have suggested that the group right the theory implies is “irreducibly collective.” I argue, to the contrary, that this group right can be grounded fully in the fundamental right of each individual to be treated as an equal by the political institutions to which he is subject. The territorial implications of the choice theory are, moreover, consistent with a plausible account of the territorial rights of states. (shrink)

A normative account of global political organization must address three fundamental questions. One concerns the way in which political jurisdictions are to be delimited and their territorial boundaries drawn; another concerns the allocation of powers of sovereignty to those jurisdictions; the third concerns the principles for the distribution of economic benefits and burdens worldwide. The aim of my dissertation is to defend an account of global justice that extends to each of these questions. In doing so, I reject the answers (...) embodied in the prevailing international states system. ;In Chapter One, I consider one of the most sophisticated attempts to defend the states system on grounds of political morality---John Rawls's "The Law of Peoples." I argue that Rawls's defense fails because it is not adequately responsive to its own animating moral ideal, namely the ideal of popular sovereignty. Properly understood, popular sovereignty imposes on global political institutions constraints that are inconsistent with the features of the states system that Rawls defends. These constraints are expressed in two conditions: a deliberativeness condition, which ensures the integrity of the communicative structures required for rational collective will formation; and a pre-commitment condition, which ensures the willing acceptance by individuals of membership in the same polity. Together, these conditions entail a set of political human rights for individuals, and a set of self-determination rights for groups. ;Thomas Pogge has proposed a federative model of global political organization that, suitably modified, is responsive to these rights. His account calls for a federative dispersion of sovereign powers among nested jurisdictions, and incorporates a voluntaristic principle for the demarcation of borders. However, Pogge's defense is incomplete. In Chapter Two, I argue that the ideal of popular sovereignty provides the necessary foundation for his model. The same ideal leads us to reject Pogge's assertion of a universal right to democratic governance. ;In Chapter Three I articulate and defend a conception of global distributive justice that mandates transfers of wealth from more- to less-affluent societies with the disjunctive target of either immigration-pressure equilibrium---roughly, the point at which all economically motivated applications for immigration are granted---or maximal human development rates for the worst-off societies worldwide.

Abstract: In this essay a set of principles is defended that yields a determinate allocation of sovereign competences across a global system of territorially nested jurisdictions. All local sovereign competences are constrained by a universal, justiciable human rights regime that also incorporates a conception of cross-border distributive justice and regulates the competence to control immigration for a given territory. Subject to human rights constraints, sovereign competences are allocated according to a conception of global democracy. The proposed allocation scheme can accommodate (...) substantial local autonomy while at the same time ensuring that everyone has a voice in the political decisions that affect his or her interests. The relevant class of affected interests is fully specified. Relevant affects are of two kinds: those that impose norms of governance on individuals, and those that impose external costs on them. The favored sense of "an external cost" is developed and defended. (shrink)

Summary A provocative examination of the consequences of Levinas’s and Adorno’s thought for contemporary ethics and political philosophy. This book sets up a dialogue between Emmanuel Levinas and Theodor W. Adorno, using their thought to address contemporary environmental and social-political situations. Eric S. Nelson explores the “non-identity thinking” of Adorno and the “ethics of the Other” of Levinas with regard to three areas of concern: the ethical position of nature and “inhuman” material others such as environments and animals; the (...) bonds and tensions between ethics and religion and the formation of the self through the dynamic of violence and liberation expressed in religious discourses; and the problematic uses and limitations of liberal and republican discourses of equality, liberty, tolerance, and their presupposition of the private individual self and autonomous subject. Thinking with and beyond Levinas and Adorno, this work examines the possibility of an anarchic hospitality and solidarity between material others and sensuous embodied life. “This is an extremely impressive, original, and thorough treatment of two key twentieth-century thinkers and their applicability to the most pressing social and political issues of our time.” — Jeffrey A. Bernstein, author of Leo Strauss on the Borders of Judaism, Philosophy, and History “This book is an excellent and timely contribution to political and environmental philosophy, located around a nuanced historical and philosophical approach to Levinas and Adorno. It will be of great interest to anyone concerned with these figures or with the current moment.” — Martin Shuster, author of Autonomy after Auschwitz: Adorno, German Idealism, and Modernity.

Daoism and Environmental Philosophy explores ethics and the philosophy of nature in the Daodejing, the Zhuangzi, and related texts to elucidate their potential significance in our contemporary environmental crisis. This book traces early Daoist depictions of practices of embodied emptying and forgetting and communicative strategies of undoing the fixations of words, things, and the embodied self. These are aspects of an ethics of embracing plainness and simplicity, nourishing the asymmetrically differentiated yet shared elemental body of life of the myriad things, (...) and being responsively attuned in encountering and responding to things. These critical and transformative dimensions of early Daoism provide exemplary models and insights for cultivating a more expansive ecological ethos, environmental culture of nature, and progressive political ecology. This work will be of interest to students and scholars interested in philosophy, environmental ethics and philosophy, religious studies, and intellectual history. (shrink)

In this wide-ranging and authoritative volume, leading scholars engage with the philosophy and writings of Wilhelm Dilthey, a key figure in nineteenth-century thought. Their chapters cover his innovative philosophical strategies and explore how they can be understood in relation to their historical situation, as well as presenting incisive interpretations of Dilthey's arguments, including their development, their content, and their influence on later thought. A key focus is on how Dilthey's work remains relevant to current debates around art and literature, the (...) biographical and autobiographical self, knowledge, language, science, culture, history, society, and psychology and the embodied mind. The volume will be important for researchers in hermeneutics, aesthetics, practical philosophy, and the history of German philosophy, providing a valuable introduction to Dilthey's work as well as detailed critical analysis of its ongoing significance.

Abstractabstract:This article examines Harold Ramis’s 2005 noir comedy The Ice Harvest as the critically dystopian counter-panel to his beloved 1993 film Groundhog Day, a film frequently discussed within the paradigm of utopia. While starkly different in genre, tone, and reception, the two films comprise a dialectical dyad that registers the historical transition from the utopian cultural effervescence of the early 1990s to the tragic foreclosure of imaginative horizons and the dystopian transformation of economic, political, and social landscapes in the new (...) millennium. In The Ice Harvest, the author argues, this is achieved through a strategic reactivation of film noir as a variant of the critical dystopia. (shrink)

Un livre pour défaire le régime esthétique de l'image, en vue d'une nouvelle pensée diagrammatique, après Deleuze et Guattari, entre art et philosophie : un ouvrage introductif et spéculatif sans équivalent qui, partant de la rupture opérée par Matisse et Duchamp avec la phénoménologie picturale de l'image esthétique, constitue une archéologie de l'art contemporain qui passe par Daniel Buren, Gordon Matta-Clark, Günter Brus et le néoconcrétisme brésilien.

For critical legal scholars, the ongoing far-right assault upon the liberal status quo poses a distinct dilemma. On the one hand, the desire to condemn the far-right is overwhelming. On the other hand, such condemnations are susceptible to being appropriated as a validation of the very liberalism that critical theorists have long questioned. In seeking to transcend this dilemma, my focus is on the discourse of ‘white genocide’ — a commonplace belief amongst the far-right/white nationalists that ‘whites’, as a discrete (...) group, are facing demographic destruction as a result of deliberate policy choices. Such a belief has motivated acts of extreme violence. While libel to dismissal by experts on mainstream understandings of genocide, namely international criminal lawyers, I argue that this ‘white genocide’ discourse deserves careful scrutiny as a jurisprudential and socio-legal phenomenon that reveals key weaknesses in present modalities of liberal justification. Drawing upon an array of recent critical theories, I show how a liberalism unable to face its own decline enables the very far-right assertions it purports to oppose. Thus, given liberalism’s failure to act as a neutral arbiter, an alternative approach for those opposing the far-right is to develop a vision of politics and society that confront believers in ‘white genocide’ on a more substantive level. This, I argue, forces the far-right’s opponents to disavow liberal scepticism towards utopian transformation as well as the juridical understandings and institutions that allow this scepticism to durably persist.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.

In the present meta-analysis, we examined the effect of cognitive training on the Executive Function (EF) of preschool children (age range: 3-6 years). We selected a final set of 32 studies from 27 papers with a total sample of 123 effect sizes. We found an overall effect of cognitive training for improving EF (g =.352; k = 123; p <.001), without significant difference between near and far transfer effects on executive domains. No significant additional outcome effects were found for behavioral- (...) and learning-related outcomes. Cognitive training programs for preschoolers are significantly more effective for developmentally at-risk children (ADHD or low socio-economic status) than for children with typical development and without risks. Other significant moderators were computerized versus non-computerized training, individual versus group sessions, and length of training. The number of sessions was not a significant moderator. This is the first demonstration of cognitive training far transfer effects among different executive processes. We discuss this result in relationship with the lower level of modularization of EFs in younger children. (shrink)

Here is a thoroughly updated edition of a classic in palliative medicine. Two new chapters have been added to the 1991 edition, along with a new preface summarizing where progress has been made and where it has not in the area of pain management.

Included are a number of compelling patient narratives. Praise for the first edition "Well (...) written. . .should be read by everyone in medical practice or considering a career in medicine."---JAMA. "Memorable passages, important ideas, and critical analysis. This is a book that clinicians and educators should read."---New England Journal of Medicine. (shrink)

Do philosophy professors specializing in ethics behave, on average, any morally better than do other professors? If not, do they at least behave more consistently with their expressed values? These questions have never been systematically studied. We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one's mother, vegetarianism, organ and blood donation, responsiveness to (...) student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues, we also had direct behavioral measures that we could compare with the self-reports. Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show unequivocally better behavior than the two comparison groups. Our findings on attitude-behavior consistency were mixed: ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation. We discuss implications for several models of the relationship between philosophical reflection and real-world moral behavior. (shrink)

This paper explains Sophie de Grouchy’s philosophical debts to Adam Smith. I have three main reasons for this: first, it should explain why eighteenth-century philosophical feminists found Smith, who has—to put it mildly—not been a focus of much recent feminist admiration, a congenial starting point for their own thinking; second, it illuminates De Grouchy’s considerable philosophical originality, especially her important, overlooked contributions to political theory; third, it is designed to remove some unfortunate misconceptions that have found their way into Karin (...) Brown’s ‘Introduction’ to the recent and much-to-be-welcomed translation of Sophie de Grouchy’s Lettres Sur La Sympathie. While Brown claims that there are major ‘differences’ in their programs of ‘social reform’, I argue there are important commonalities between Smith and De Grouchy. In particular, I highlight how they share a common understanding of how human sensibilities are shaped by social institutions and I show that De Grouchy’s path-breaking analysis of negative and positive liberty is grounded in her extension of Smith’s political theory and moral psychology.

This work focuses on the reading and analysis of the work of Nicholas Machiavelli made by the Argentinian historian José Luis Romero in several of his historical and historiographical writings. It attends, particularly, to the assessment that Romero has made of the famous Florentine thinker as historian. From this perspective, it will be studied the impact of the Machiavellian work on the thought and intellectual work of the Argentinian academician. This work seeks to show that Machiavelli was, for the aforementioned (...) author of the 20th Century, a source of inspiration, a master in the analysis of “the real reality” and an example of commitment to public affairs. However, Machiavelli's work entailed a strong warning for him: there must be proper balance between academic rigor and political com­mitment, between the historian's own claim to truth and the citizen's ideological position.

It has been widely demonstrated that dreaming occurs throughout human sleep. However, we once again are facing new variants of the equation “REM sleep = Dreaming.” Nielsen proposes a model that assumes covert REM processes in NREM sleep. I argue against this possibility, because dream research has shown that REM sleep is not a necessary condition for dreaming to occur. [Nielson].

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment. Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

From the time of Locke, discussions of personal identity have often ignored the question of our basic metaphysical nature: whether we human people are biological organisms, spatial or temporal parts of organisms, bundles of perceptions, or what have you. The result of this neglect has been centuries of wild proposals and clashing intuitions. What Are We? is the first general study of this important question. It beings by explaining what the question means and how it differs from others, such as (...) questions of personal identity and the mind-body problem. It then examines in some depth the main possible accounts of our metaphysical nature, detailing both their theoretical virtues and the often grave difficulties they face. The book does not endorse any particular account of what we are, but argues that the matter turns on more general issues in the ontology of material things. If composition is universal--if any material things whatever make up something bigger--then we are temporal parts of organisms. If things never compose anything bigger, so that there are only mereological simples, then we too are simples--perhaps the immaterial substances of Descartes--or else we do not exist at all (a view Olson takes very seriously). The intermediate view that some things compose bigger things and others do not leads almost inevitably to the conclusion that we are organisms. So we can discover what we are by working out when composition occurs. (shrink)

The changes in the short version of Leontios of Neapolis’ Life of John the Almsgiver are analyzed in order to evaluate their cause and to expose their literary character. It is shown that the saint’s oaths are suppressed due to a misunderstanding of a passage in the Prologue, and by respect of the Evangelical commandment. The short version also eliminates pagan concepts of fortune, emphasises the social hierarchy, the accordance between words and thoughts, the action of God as a cause (...) of miracles, and avoids to name God as a reason. The short version raises the stylistical level of the text using the methods of the Metaphrast which is common in the 10th century. The textual tradition also allows to date it into this century. The long version is surely the original text, and the changes made to it show a cultural change between the 7th and 10th centuries. (shrink)

Plato argues that four political arts—politics, kingship, slaveholding, and household-management—are the same. His argument, which prompted Aristotle’s reply in Politics I, has been universally panned. The problem is that the argument clearly identifies household-management with slaveholding, and household-management with politics, but does not fully identify kingship with any of the others. I consider and reject three ways of saving the argument, and argue for a fourth. On my view, Plato assumes that politics is identical with kingship, just as he does (...) elsewhere, but he begs no questions because the point of his argument is to identify the public arts of politics and kingship with the private arts of household-management and slaveholding. He does this successfully by answering three reasons why one might distinguish the private from the public arts. His argument leaves room for Aristotle to propose other reasons. One of them—involving differences among men and women and slaves—is unfortunate, but another is more promising. The Aristotelian can assume that political expertise is a matter of know-how gathered by experience of the particular actions which differ in the public and private arts. But Plato might well be right to reject this, and to insist that the essential difference between the expert and non-expert—the dividing line between good and bad rule—is not in experience but in their grasp of their goals.

Some argue that the term “explanation” in science is ambiguous, referring to at least three distinct concepts: a communicative concept, a representational concept, and an ontic concept. Each is defined in a different way with its own sets of norms and goals, and each of which can apply in contexts where the others do not. In this paper, I argue that such a view is false. Instead, I propose that a scientific explanation is a complex entity that can always be (...) analyzed along a communicative dimension, a representational dimension, and an ontic dimension. But all three are always present within scientific explanations. I highlight what such an account looks like, and the potential problems it faces (namely that a single explanation can appear to have incompatible sets of norms and goals that govern it). I propose a solution to this problem and demonstrate how this account can help to dissolve current disputes in philosophy of science regarding debates between epistemic and ontic accounts of mechanistic explanations in the life sciences.
