We prove that if p ≠ q are distinct primes, then the classification problems for p-local and q-local torsion-free abelian groups of rank two are incomparable with respect to Borel reducibility.

Safe stair negotiation is an everyday task that children with developmental coordination disorder are commonly thought to struggle with. Yet, there is currently a paucity of research supporting these claims. We investigated the visuomotor control strategies underpinning stair negotiation in children with and without DCD by measuring kinematics, gaze behavior and state anxiety as they ascended and descended a staircase. A questionnaire was administered to determine parents' confidence in their child's ability to safely navigate stairs and their child's fall history. (...) Kinematics were measured using three-dimensional motion capture, whilst gaze was measured using mobile eye-tracking equipment. The parents of DCD children reported significantly lower confidence in their child's ability to maintain balance on the stairs and significantly more stair-related falls in the previous year compared to the parents of typically developing children. During both stair ascent and stair descent, the children with DCD took longer to ascend/descend the staircase and displayed greater handrail use, reflecting a more cautious stair negotiation strategy. No differences were observed between groups in their margin of stability, but the DCD children exhibited significantly greater variability in their foot-clearances over the step edge, which may increase the risk of a fall. For stair descent only, the DCD children reported significantly higher levels of state anxiety than the TD children and looked significantly further along the staircase during the initial entry phase, suggesting an anxiety-related response that may bias gaze toward the planning of future stepping actions over the accurate execution of an ongoing step. Taken together, our findings provide the first quantifiable evidence that safe stair negotiation is a significant challenge for children with DCD, and that this challenge is reflected by marked differences in their visuomotor control strategies and state anxiety levels. Whilst it is currently unclear whether these differences are contributing to the frequency of stair-related falls in children with DCD, our findings pave the way for future research to answer these important questions.

The miniseries Frank Herbert’s Dune (2000) and Frank Herbert’s Children of Dune (2003) offer a stark warning that people must think for themselves rather than relying on authority. In particular, they warn against overreliance on leaders and on religious authorities. The series tell the story of how, in the far future, Paul Atreides becomes dictator and religious leader over the human race, bringing slaughter and oppression in his wake. The chapter will consider the views of philosophers like Plato, who believed (...) that power should be concentrated in the hands of leaders with absolute authority, along with the views of philosophers who advocated democracy, like John Locke, John Stuart Mill, and John Dewey. The chapter will also examine the views of philosophers on religion, especially philosophers critical of religion, such as Locke, Thomas Paine, and Bertrand Russell. It is argued that the series present a strong case against allowing others to think for us, because the story they tell matches the historical record of the real world. When leaders have been given the power to be arbiters of truth, they have too often exploited those beneath them, using their positions to accumulate wealth, power, and glory. When too much trust has been placed in religious authority, it has likewise too often led to exploitation and repression. What is worse, the power of religion is uncontrollable, easily leading to violence and destruction. Having said that, the series fail to reflect that religion does good in the world. This chapter argues that, as maintained by W. K. Clifford, whether people should accept religious views depends on whether they have good grounds to believe that these views are true. This implies that people must not accept religious views without thinking the views through for themselves. (shrink)

This essay is an examination of Dante Alighieri as a spiritual theologian of grace. Using Cantos 9 and 29–30 of the Purgatorio the essay shows that Dante constructs his other-worldly journey as one that is grace-filled and dependent on the grace bestowed through the church's sacraments, in concert with Thomas Aquinas’ theology of grace. Further, in light of the creation of the Feast of Corpus Christi in the thirteenth century, the essay offers a unique interpretation of the figure of (...) Beatrice, showing that she, at least within the context of Purgatorio 29–30, is divine grace. (shrink)

Nowadays references to the afterlife-angels strumming harps, demons brandishing pitchforks, God enthroned on heavenly clouds-are more often encountered in New Yorker cartoons than in serious Christian theological reflection. Speculation about death and its sequel seems to embarrass many theologians; however, as Greg Garrett shows in Entertaining Judgment, popular culture in the U.S. has found rich ground for creative expression in the search for answers to the question: What lies in store for us after we die? The lyrics of Madonna, (...) Los Lonely Boys, and Sean Combs; the plotlines of TV's Lost, South Park, and The Walking Dead; the implied theology in films such as The Dark Knight, Ghost, and Field of Dreams; the heavenly half-light of Thomas Kinkade's popular paintings; the ghosts, shades, and after-life way-stations in Harry Potter; and the characters, situations, and locations in the Hunger Games saga all speak to our hopes and fears about what comes next. In a rich survey of literature and popular media, Garrett compares cultural accounts of death and the afterlife with those found in scripture. Denizens of the imagined afterlife, whether in heaven, hell, on earth, or in purgatory, speak to what awaits us, at once shaping and reflecting our deeply held-if often somewhat nebulous-beliefs. They show us what rewards and punishments we might expect, offer us divine assistance, and even diabolically attack us. Ultimately, we are drawn to these stories of heaven, hell, and purgatory--and to stories about death and the undead--not only because they entertain us, but because they help us to create meaning and to learn about ourselves, our world, and, perhaps, the next world. Garrett's deft analysis sheds new light on what popular culture can tell us about the startlingly sharp divide between what modern people profess to believe and what they truly hope and expect to find after death--and how they use those stories to help them understand this life.

For much of the second half of the 20th Century, the primary role logical empiricism played was that of the argumentative foil. The 'received view' on a given topic (especially in philosophy of science, logic, or language) was frequently identified with some supposedly dogmatic tenet of logical empiricism. However, during the last twenty-five years, scholars have paid serious, sustained attention to what the logical positivists, individually and collectively, actually said. Early scholarship on logical empiricism had to engage in heavy-duty PR (...) work: why should anyone study the now-discarded mixture of blunders and implausibilities collected under the label 'logical empiricism'? However, thanks to the efforts of the pioneers, people studying the logical empiricists today need not articulate an extended apologia for their chosen subject of study -- rather, they can simply get on with their work. Many of the best fruits of these recent labors are on display in The Cambridge Companion to Logical Empiricism (CCLE), edited by Alan Richardson and Thomas Uebel. (shrink)

Bounds consequence provides an interpretation of a multiple-conclusion consequence relation in which the derivability of a sequent is understood as the claim that it is conversationally out-of-bounds to take a position in which each member of Γ is asserted while each member of Δ is denied. Two of the foremost champions of bounds consequence—Greg Restall and David Ripley—have independently indicated that the shape of the bounds in question is determined by conversational practice. In this paper, I suggest that the (...) standard treatments of bounds consequence have focused heavily on the matter of veridicality at the expense of ignoring other features by which conversational bounds are set, prime among them being the matter of content or subject-matter. Furthermore, I argue that the semantic behavior of propositions containing “monstrous” content—content whose introduction is inappropriate to a context independently of veridical considerations—leads to a weak Kleene account of bounds consequence.

Sport continues to be one of the primary means through which notions of Englishness and Britishness are constructed, contested, and resisted. The legacy of the role of sport in the colonial project of the British Empire, combined with more recent connections between sport and far right fascist/nationalist politics, has made the association between Britishness, Englishness, and ethnic identity(ies) particularly intriguing. In this paper, these intersections are explored through British media coverage of the Canadian‐born, British tennis player, Greg Rusedski. This (...) coverage is examined through the lens of ‘performativity,’ as articulated by Judith Butler. Through a critical application of Butler's ideas, the ways in which the media seek to recognise and normalise certain identities, while problematising and excluding others, can be more fully appreciated. Thus, it was within newspaper framings of Rusedski that hegemonic notions of White Englishness could be performed, maintained, and embedded. (shrink)

In view of scholarly work that has explored the socio-psycho significance of national performativity, the body and the “other,” this article critically analyses newspaper representations of the Canadian-born British tennis player Greg Rusedski. Drawing on Lacanian interpretations of the body, it illustrates how Rusedski’s media framing centered on a particular feature of his body—his “smile.” In doing so, we detail how Rusedski’s “post-imperial” Otherness—conceived as a form of “extimacy” (extimité)—complicated any clear delineation between “us” and “them,” positing instead a (...) dialectical understanding of the splits, voids and contradictions that underscore the national “us.”.

A.P. Martinich's interpretation that in Leviathan Thomas Hobbes believed that the laws of nature are the commands of God and that he did not rely on the Bible to prove this has been criticized by Greg Forster in this journal (2003). Forster uses these criticisms to develop his own view that Hobbes was insincere when he professed religious beliefs. We argue that Forster misrepresents Martinich's view, is mistaken about what evidence is relevant to interpreting whether Hobbes was sincere (...) or not, and is mistaken about some of Hobbes's central doctrines. Forster's criticisms are worth discussing at length for at least three reasons. He takes the debate about Hobbes's sincerity to a new level of sophistication; his misinterpretations of Hobbes may become accepted as correct; and his criticisms raise issues about the proper method of interpreting historical texts.

Something has been going wrong on many college campuses in the last few years. Speakers are shouted down. Students and professors say they are walking on eggshells and are afraid to speak honestly. Rates of anxiety, depression, and suicide are rising--on campus as well as nationally. How did this happen? First Amendment expert Greg Lukianoff and social psychologist Jonathan Haidt show how the new problems on campus have their origins in three terrible ideas that have become increasingly woven into (...) American childhood and education: What doesn't kill you makes you weaker; always trust your feelings; and life is a battle between good people and evil people. These three Great Untruths contradict basic psychological principles about well-being and ancient wisdom from many cultures. Embracing these untruths--and the resulting culture of safetyism--interferes with young people's social, emotional, and intellectual development. It makes it harder for them to become autonomous adults who are able to navigate the bumpy road of life. Lukianoff and Haidt investigate the many social trends that have intersected to promote the spread of these untruths. They explore changes in childhood such as the rise of fearful parenting, the decline of unsupervised, child-directed play, and the new world of social media that has engulfed teenagers in the last decade. They examine changes on campus, including the corporatization of universities and the emergence of new ideas about identity and justice. They situate the conflicts on campus within the context of America's rapidly rising political polarization and dysfunction. This is a book for anyone who is confused by what is happening on college campuses today, or has children, or is concerned about the growing inability of Americans to live, work, and cooperate across party lines.

In an attempt to address the theoretical gap between linguistics and philosophy, a group of semanticists, calling itself the Generic Group, has worked to develop a common view of genericity. Their research has resulted in this book, which consists of a substantive introduction and eleven original articles on important aspects of the interpretation of generic expressions. The introduction provides a clear overview of the issues and synthesizes the major analytical approaches to them. Taken together, the papers that follow reflect the (...) current state of the art in the semantics of generics, and afford insight into various generic phenomena. (shrink)

NEW YORK TIMES BESTSELLER • More than one million copies sold! Essentialism isn’t about getting more done in less time. It’s about getting only the right things done. “A timely, essential read for anyone who feels overcommitted, overloaded, or overworked.”—Adam Grant Have you ever: • found yourself stretched too thin? • simultaneously felt overworked and underutilized? • felt busy but not productive? • felt like your time is constantly being hijacked by other people’s agendas? If you answered yes to any (...) of these, the way out is the Way of the Essentialist. Essentialism is more than a time-management strategy or a productivity technique. It is a systematic discipline for discerning what is absolutely essential, then eliminating everything that is not, so we can make the highest possible contribution toward the things that really matter. By forcing us to apply more selective criteria for what is Essential, the disciplined pursuit of less empowers us to reclaim control of our own choices about where to spend our precious time and energy—instead of giving others the implicit permission to choose for us. Essentialism is not one more thing—it’s a whole new way of doing everything. It’s about doing less, but better, in every area of our lives. Essentialism is a movement whose time has come. (shrink)

Big Ideas for Little Kids includes everything a teacher, a parent, or a college student needs to teach philosophy to elementary school children from picture books. Written in a clear and accessible style, the book explains why it is important to allow young children access to philosophy during primary-school education. Wartenberg also gives advice on how to construct a "learner-centered" classroom, in which children discuss philosophical issues with one another as they respond to open-ended questions by saying whether they agree (...) or disagree with what others have said.

Should organ transplants be given to patients who have waited the longest, or need it most urgently, or those whose survival prospects are the best? The rationing of health care is universal and inevitable, taking place in poor and affluent countries, in publicly funded and private health care systems. Someone must budget for as well as dispense health care whilst aging populations severely stretch the availability of resources. The Ethics of Health Care Rationing is a clear and much-needed introduction to (...) this increasingly important topic, considering and assessing the major ethical problems and dilemmas about the allocation, scarcity and rationing of health care. Beginning with a helpful overview of why rationing is an ethical problem, the authors examine the following key topics: What is the value of health? How can it be measured? What does it mean that a treatment is "good value for money"? What sort of distributive principles - utilitarian, egalitarian or prioritarian - should we rely on when thinking about health care rationing? Does rationing health care unfairly discriminate against the elderly and people with disabilities? Should patients be held responsible for their health? Why does the debate on responsibility for health lead to issues about socioeconomic status and social inequality? Throughout the book, examples from the US, UK and other countries are used to illustrate the ethical issues at stake. Additional features such as chapter summaries, annotated further reading and discussion questions make this an ideal starting point for students new to the subject, not only in philosophy but also in closely related fields such as politics, health economics, public health, medicine, nursing and social work.

In barely the space of one generation, Athens was transformed from a conventional city-state into something completely new--a region-state on a scale previously unthinkable. This book sets out to answer a seemingly simple question: How and when did the Athenian state attain the anomalous size that gave it such influence in Greek politics and culture in the classical period? Many scholars argue that Athens's incorporation of Attica was a gradual development, largely completed some two hundred years before the classical era. (...) Anderson, however, suggests that it is not until the late sixth century that we see the first systematic attempts by the Athenian polis to integrate all of Attica. Anderson first takes issue with the prevailing view of Cleisthenes' landmark political reforms of 508-7 b.c., arguing that they were animated by a more comprehensive vision of regional political community in Attica. The Athenians' strengthened the state by establishing institutional mechanisms that would allow inhabitants of the Attic periphery to participate as never before in the life of the center. The creation of a suitable physical setting for the new order was accompanied by religious, military, and symbolic innovations. Regional participation in Athenian affairs was stimulated by encouraging the Attic populace to imagine themselves, for the first time ever, as members of a single, like-minded, self-governing political community.

I am grateful to Catharine Abell and Jonathan Gilmore for their comments and for the opportunity to think again about some important questions. Before I respond.

The idea that fictions may educate us is an old one, as is the view that they distort the truth and mislead us. While there is a long tradition of passionate assertion in this debate, systematic arguments are a recent development, and the idea of empirically testing is particularly novel. Our aim in this chapter is to provide clarity about what is at stake in this debate, what the options are, and how empirical work does or might bear on its (...) resolution. We distinguish between merely influencing people’s opinions and providing genuine learning, where the latter requires that the source of the change in opinion should be reliable. Other important ideas here are the extent to which authors of fiction may be considered to provide testimony, or something like it, and the possibility of recognizing an unstated purpose in the project of the fictional work. We ask whether fictions can furnish us not merely with ideas but with reasons for believing them, perhaps by constituting thought experiments. We consider whether the focus should be on understanding rather than on knowledge, and whether fictions can inform us about the qualities of another’s experiences. We briefly describe some experimental work of recent decades and suggest that the evidence for learning from fiction is currently meagre. (shrink)

According to classical and postclassical sources, the early Greek turannoi were, by definition, illegitimate rulers who overturned existing political arrangements and installed rogue monarchic regimes in their place. And on this one fundamental point at least, modern observers of archaic turannides seem to have little quarrel with their ancient informants. To this day, it remains axiomatic that Cypselus, Peisistratus, and the rest were autocrats who gained power by usurpation. Whatever their individual accomplishments, they were still, in a word, "tyrants." Relying (...) mostly on evidence from the contemporary literary and material records, my paper aims to challenge this time-honored conventional wisdom and restore the first turannoi to the political mainstream.

In many societies, the aging of the population is becoming a major problem. This raises difficult issues for ethics and public policy. On what is known as the fair innings view, it is not impermissible to give lower priority to policies that primarily benefit the elderly. Philosophers have tried to justify this view on various grounds. In this article, I look at a consequentialist, a fairness-based, and a contractarian justification. I argue that all of them have implausible implications and fail (...) to correspond to our moral intuitions. I end by outlining a different kind of consequentialist justification that avoids those implications and corresponds better to our considered moral judgments. (shrink)

In the near future developments in non-invasive prenatal testing may soon provide couples with the opportunity to test for and diagnose a much broader range of heritable and congenital conditions than has previously been possible. Inevitably, this has prompted much ethical debate on the possible implications of NIPT for providing couples with opportunities for reproductive choice by way of routine prenatal screening. In view of the possibility to test for a significantly broader range of genetic conditions with NIPT, the European (...) Society of Human Genetics and American Society of Human Genetics recommend that, pending further debate, prenatal screening for reproductive choice should only be offered where concerning serious congenital conditions and childhood disorders. In support of this recommendation, the ESHG and ASHG discuss a number of ethical issues on which they prompt further debate: the informational privacy of the future child, the trivialization of abortion, the risk of information overload, and issues of distributive justice. This paper responds to this call with further reflection on each ethical issue and how it relates to the moral justification of providing couples with opportunities for meaningful reproductive choice. The paper concludes that whilst there may be good reasons for qualifying the scope of any unsolicited prenatal screening offer to serious congenital conditions and childhood disorders, if prenatal screening is justified for providing couples with opportunities for meaningful reproductive choice, then health services may have obligations to empower couples with the same opportunity where concerning other conditions.

Cette étude essaye d’établir qu’il y a deux notions très différentes de « fondation » à l’œuvre dans les Recherches logiques de Husserl. Dans la IIIème Recherche, où le terme est formellement introduit, lorsqu’il se demande quels sont les contenus qui peuvent exister d’une manière autonome (indépendants) et lesquels peuvent exister uniquement en tant que moments d’autre chose (dépendants), Husserl suit ce que j’appelle un « modèle ontologique ». Selon ce modèle, le concret possède une priorité sur à l’abstrait qui (...) est fondé en lui. Dans la VIème Recherche, en revanche, Husserl s’oriente principalement sur un « modèle gnoséologique » qui voit le complexe comme fondé sur ce qui est relativement simple, étant donné que les expériences d’ordre supérieur (telles les perceptions de types d’objets plus complexes) sont « fondées sur » des expériences plus simples, bien qu’elles ne puissent pas y être réduites. L’exemple principal ici est celui des intuitions catégoriales : fondées sur les intuitions sensibles, elles n’y sont pas réductibles. Mais cette distinction entre deux sens différents du terme de « fondation » peut également nous aider à mieux comprendre de nombreuses thèses husserliennes plutôt controversées. Par exemple, elle peut nous permettre de mieux comprendre dans quelle mesure faire l’expérience d’un être humain comme un tout se fonde sur l’expérience d’un corps physique, et cela même si l’étant que nous rencontrons inclut à la fois des aspects corporels et des aspects spirituels – les deux étant vus, d’une manière essentielle, comme des moments de cette unique personne qui fait l’objet de notre expérience.

Developments in Non-Invasive Prenatal Testing (NIPT) and cell-free fetal DNA analysis raise the possibility that antenatal services may soon be able to support couples in non-invasively testing for, and diagnosing, an unprecedented range of genetic disorders and traits coded within their unborn child’s genome. Inevitably, this has prompted debate within the bioethics literature about what screening options should be offered to couples for the purpose of reproductive choice. In relation to this problem, the European Society of Human Genetics (ESHG) and (...) American Society of Human Genetics (ASHG) tentatively recommend that any expansion of this type of screening, as facilitated by NIPT, should be limited to serious congenital and childhood disorders. In support of this recommendation, the ESHG and ASHG cite considerations of distribution justice. Notably, however, an account of justice in the organization and provision of this type of screening which might substantiate this recommendation has yet to be developed. This paper attempts to redress this oversight through an investigation of Norman Daniels’ theory of Just health: meeting health needs fairly. In line with this aim, the paper examines what special moral importance (for Just health) screening for the purpose of reproductive choice might have where concerning serious congenital and childhood disorders in particular. The paper concludes that screening for reproductive choice where concerning serious congenital and childhood disorders may be important for providing women with fair opportunity to protect their health (by either having or not having an affected child).

Some philosophers and disability advocates argue that disability is not bad for you.

In early 2017, Nevada amended its Uniform Determination of Death Act, in order to clarify the neurologic criteria for the determination of death. The amendments stipulate that a determination of death is a clinical decision that does not require familial consent and that the appropriate standard for determining neurologic death is the American Academy of Neurology’s guidelines. Once a physician makes such a determination of death, the Nevada amendments require the withdrawal of life-sustaining treatment within twenty-four hours with limited exceptions. (...) Neurologists have generally supported Nevada’s amendments for clarifying the diagnostic standard and limiting the ability of family members to challenge it. However, it is more appropriate to view the Nevada amendments with concern. Even though the primary purpose of the UDDA is to ensure that all functions of a person’s entire brain have ceased, the AAN guidelines do not accurately assess this. In addition, by characterizing the determination of death as solely a clinical decision, the Nevada legislature has improperly ignored the doctrine of informed consent, as well as the beliefs of particular faiths and cultures that reject brain death. Rather than resolving controversies regarding brain death determinations, the Nevada amendments may instead instigate numerous constitutional challenges. (shrink)

Technological progress may eventually produce sophisticated robots with human-like traits that result in humans forming meaningful relationships with them. Such relationships would likely lead to a demand for human–artificial intelligence matrimony. U.S. Supreme Court decisions that expanded the definition of marriage to include interracial and same-sex couples, as well as those that have not extended marriage to polygamous relationships, provide guidance regarding the criteria that human–AI would have to meet to successfully assert a right to marry. Ultimately, robots will have (...) to possess certain characteristics of personhood to marry, including the capacity to contract and to engage in an intimate relationship. Alternatively, if AIs can simulate these abilities sufficiently, we may believe that they have these capacities. Even if AIs genuinely possess the capabilities necessary to enter into a marriage, it is social acceptance of intelligent non-humans as life partners that will likely influence legal development is this realm rather than personhood criteria. However, AIs are likely to face bias due to their “artificial” rather than biological nature. Yet, Peter Singer’s influential argument regarding speciesism in the context of animal rights implies that AIs with specific human-like qualities cannot be justifiably denied certain rights.

It is argued that the English bare plural (an NP with plural head that lacks a determiner), in spite of its apparently diverse possibilities of interpretation, is optimally represented in the grammar as a unified phenomenon. The chief distinction to be dealt with is that between the generic use of the bare plural (as in Dogs bark) and its existential or indefinite plural use (as in He threw oranges at Alice). The difference between these uses is not to be accounted (...) for by an ambiguity in the NP itself, but rather by explicating how the context of the sentence acts on the bare plural to give rise to this distinction. A brief analysis is sketched in which bare plurals are treated in all instances as proper names of kinds of things. A subsidiary argument is that the null determiner is not to be regarded as the plural of the indefinite article a. (shrink)

:The distinction between brute luck and option luck is fundamental for luck egalitarianism. Many luck egalitarians write as if it could be used to specify which outcomes people should be held responsible for. In this paper, I argue that the distinction can’t be used this way. In fact, luck egalitarians tend to rely instead on rough intuitive judgements about individual responsibility. This makes their view vulnerable to what’s known as the neutrality objection. I show that attempts to avoid this objection (...) are unsuccessful. I conclude that until it provides a better account of attributing responsibility, luck egalitarianism remains incomplete.

Some empirical findings seem to show that people value health benefits differently depending on the age of the beneficiary. Health economists and philosophers have offered justifications for these preferences on grounds of both efficiency and equity. In this paper, I examine the most prominent examples of both sorts of justification: the defence of age-weighting in the WHO's global burden of disease studies and the fair innings argument. I argue that neither sort of justification has been worked out in satisfactory form: (...) age should not be taken into account in the framework of the burden of disease measure, and on the most promising formulations of the fair innings argument, it turns out to be merely an indicator of some other factor. I conclude by describing the role of age in theories of justice of healthcare resource allocation. (shrink)
