Sober (1992) has recently evaluated Brandon's (1982, 1990; see also 1985, 1988) use of Salmon's (1971) concept of screening-off in the philosophy of biology. He critiques three particular issues, each of which will be considered in this discussion.

Comparisons between modally and amodally completed regions show that perceptual filling-in is not merely the ignoring of absences. Illusory filled-in colour arises for modal completion, but not for amodal completion in comparable displays. We find that attention spreads automatically to modally but not amodally completed regions from their inducers, revealing a functional effect of filled-in colour.

The complex relationship between attention and STM forms a core issue in the study of human cognition, and Cowan's target article attempts, quite successfully, to elucidate an important part of this relationship. However, while I agree that aspects of STM performance may reflect the action mechanisms that we normally consider to subserve “ attention ” I shall argue here that attention is not subject to a fixed four-object capacity limit as Cowan suggests. Rather, performance in attention tasks as well as (...) STM may be best accounted for in terms of decay and interference. (shrink)

There exists no completely satisfactory theory of risk attitude in current normative decision theories. Existing notions confound attitudes to pure risk with unrelated psychological factors such as strength of preference for certain outcomes, and probability weighting. In addition traditional measures of risk attitude frequently cannot be applied to non-numerical consequences, and are not psychologically intuitive. I develop Pure Risk theory which resolves these problems – it is consistent with existing normative theories, and both internalises and generalises the intuitive notion of (...) risk being related to the probability of not achieving one’s aspirations. Existing models which ignore pure risk attitudes may be misspecified, and effects hitherto modelled as loss aversion or utility curvature may be due instead to Pure Risk attitudes. (shrink)

We respond to Stephen T. Davis’ criticism of our earlier essay, “Assessing the Resurrection Hypothesis.” We argue that the Standard Model of physics is relevant and decisive in establishing the implausibility and low explanatory power of the Resurrection hypothesis. We also argue that the laws of physics have entailments regarding God and the supernatural and, against Alvin Plantinga, that these same laws lack the proviso “no agent supernaturally interferes.” Finally, we offer Bayesian arguments for the Legend hypothesis and against (...) the Resurrection hypothesis.

The two-dimensional modal logic of Davies and Humberstone [3] is an important aid to our understanding the relationship between actuality, necessity and a priori knowability. I show how a cut-free hypersequent calculus for 2D modal logic not only captures the logic precisely, but may be used to address issues in the epistemology and metaphysics of our modal concepts. I will explain how the use of our concepts motivates the inference rules of the sequent calculus, and then show that the completeness (...) of the calculus for Davies–Humberstone models explains why those concepts have the structure described by those models. The result is yet another application of the completeness theorem. (shrink)

In response to Stephen Davis’s criticism of our previous essay, we revisit and defend our arguments that the Resurrection hypothesis is logically incompatible with the Standard Model of particle physics—and thus is maximally implausible—and that it cannot explain the sensory experiences of the Risen Jesus attributed to various witnesses in the New Testament—and thus has low explanatory power. We also review Davis’s reply, noting that he evades our arguments, misstates their conclusions, and distracts the reader with irrelevancies regarding, (...) e.g., what natural laws are, what a miracle is, and how “naturalism” and “supernaturalism” differ as worldviews. Contrary to what Davis claims (even in his abstract), we do not argue that “if the Standard Model of particle physics is true, then the resurrection of Jesus did not occur and physical things can only causally interact with other physical things.” Davis distorts our claims and criticizes straw men of his own creation.

Drawing on contexts of critical theory offered by Simone de Beauvoir, Herbert Marcuse, and Angela Davis, this article argues that Alain Locke’s theory of valuation should be of interest to theorists who apprehend struggle as a process of desire. Locke’s value theory with its classification of “form-feelings” may be used to develop appreciation for value’s genealogical dependence on desire. This has consequences for theorizing the challenges faced by liberation from oppressive structures. A case study is provided from popular film.

Greg Bognar has recently offered a prioritarian justification for ‘fair innings’ distributive principles that would ration access to healthcare on the basis of patients' age. In this article, I agree that Bognar's principle is among the strongest arguments for age-based rationing. However, I argue that this position is incomplete because of the possibility of ‘time-relative' egalitarian principles that could complement the kind of lifetime egalitarianism that Bognar adopts. After outlining Bognar's position, and explaining the attraction of time-relative egalitarianism, I (...) suggest various ways in which these two kinds of principle could interact. Since various options have very different implications for age-based rationing, proponents of such a rationing scheme must take a position on time-relative egalitarianism to complement a lifetime prioritarian view like Bognar's.

La menzogna è irrinunciabile per vincere in politica? Davi ci spiega quali sono i meccanismi di persuasione a cui ricorrono taluni politici per farsi eleggere e quali le responsabilità di quegli elettori che scelgono comunque di votare chi sostiene anche ciò che non può essere vero. È indubbio che la comunicazione politica si rifaccia al simbolismo e al linguaggio delle favole; non necessariamente per occultare la realtà, ma più direttamente per esprimere con maggiore efficacia il suo messaggio. Alle celebri favole (...) di 'Biancaneve', 'Cenerentola', 'Il brutto anatroccolo' sono ricorsi infatti uomini politici del calibro di Berlusconi, Prodi, Nixon, Carter, Mitterrand e partiti quali la Democrazia Cristiana; l'hanno fatto per conquistare voti ma anche per attivare ampi meccanismi di consenso che attingessero direttamente dall'inconscio collettivo. Le conseguenze - ammonisce l'autore - possono essere molto serie, come nel caso dell'attuale politica americana che ha portato la manipolazione e l'inganno a essere riconosciuti come tratti identitari della presidenza di George W. Bush. (shrink)

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)

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.

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.

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.

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)

Western philosophers have traditionally concentrated on theory as the means for expressing knowledge about a variety of phenomena. This absorbing book challenges this fundamental notion by showing how objects themselves, specifically scientific instruments, can express knowledge. As he considers numerous intriguing examples, Davis Baird gives us the tools to "read" the material products of science and technology and to understand their place in culture. Making a provocative and original challenge to our conception of knowledge itself, _Thing Knowledge _demands that (...) we take a new look at theories of science and technology, knowledge, progress, and change. Baird considers a wide range of instruments, including Faraday's first electric motor, eighteenth-century mechanical models of the solar system, the cyclotron, various instruments developed by analytical chemists between 1930 and 1960, spectrometers, and more.

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.

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).

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)

When we read On the Origin of Species, we cannot help but hear echoes of the Wealth of Nations. Darwin’s “economy of nature” features a “division of labour” that leads to complexity and productivity. We should not, however, analyze Darwin’s ethics through this lens. Darwin did not draw his economic ideas from Smith, nor did he base his ethics on an economic foundation. Darwin’s ethics rest on Smith’s notion—from the Theory of Moral Sentiments—of an innate human faculty of sympathy. Darwin (...) gave this notion an evolutionary interpretation, concluding that any species of social animals that develops a high enough level of intelligence will evolve moral principles. But the specific moral principles evolved by any particular species will vary, depending on that species’ particular evolutionary history. Darwin’s theory of moral sentiments thus diverged profoundly from Smith’s, while remaining in the same intellectual lineage. Although my reading of Darwin’s ethics departs from the dominant trend, it is not without precedent. A century ago, William James propounded a similar interpretation of Darwin. James’s interpretation has been largely forgotten, but he had Darwin right. It seems that James then developed his own moral philosophy on what he saw as a Darwinian foundation. It may be that James read Darwin’s evolutionary ethics through a pragmatic lens and so refashioned it, in his turn, into something again profoundly different from what Darwin had conceived, but again remaining in the same intellectual lineage.

This article underlines and draws attention to critical insights Esposito makes regarding the prospects of rethinking community in a globalized world. Alongside Agamben and Nancy, Esposito challenges the property prejudice found in mainstream models of community.

Esposito responds to this problem by developing what I call a “deontological communal contract” where being and (...) ethics are prioritized over having and economics. I examine this new perspective on community in relation to mainstream models found in contemporary and classical social theory. (shrink)

Rather than a prescriptive, step-by-step book, After Awareness is a presentation of how the Direct Path works, examining lesser-known aspects of the path and providing context, examples, and critiques of its methods. You'll learn how to use the tools of non-dual self-inquiry-as well as when to discard them-and find a set of less doctrinaire terms and pointers for discussing non-dual awareness and the (...) Direct Path in a twenty-first-century context. With this open, pragmatic, and deconstructive approach, you'll see the Direct Path from all angles and be able to draw your own conclusions. You'll also discover ways to talk about self-inquiry and non-dual awareness in mixed settings. Most important, you'll learn how an exploration that begins with everyday perspectives and experiential investigations into the nature of the "I" can lead to a sense of true peace, free from all judgments and self-consciousness.

Karl Popper defines an ad hoc hypothesis as one that is introduced to immunize a theory from some (or all) refutation but which cannot be tested independently. He has also attempted to explicate ad hocness in terms of certain other allegedly undesirable properties of hypotheses or of the explanations they would provide, but his account is confused and mistaken. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which need not be. (...) In the former case, I argue that non-circularity is in any event preferable to non-ad hocness as a necessary condition for a satisfactory explanation or an explanans, as the case may be, and I try to sort out various persistent errors surrounding this comparison. In the latter case, I suggest that Popper is barking up the wrong tree, that important scientific progress sometimes does consist in just such reductions in empirical content as he proscribes. This provides a further reason for not taking ad hoc hypotheses as Popper conceives them to pose the danger for science he believes they do. (shrink)

Loïc Wacquant argues for a radicalization of the habitus concept provided by Pierre Bourdieu, suggesting that habitus is a site and mode for conducting research, not simply an explanatory or theoretical mechanism. Taking seriously this call to examine skills and communities of practice through apprenticeship, however, requires that the theoretical account of habitus be subject to empirical testing. Moreover, enquiry into communities of practice, especially the subtle psychological, behavioural and even neurological consequences of skill acquisition, means that claims about the (...) habitus can be scrutinized by fields such as psychology, neurology and even human biology. Habitus as a truly open path of inquiry will demand, not wholly novel concepts, but a recognition of when claims about practice are simultaneously testable, and falsifiable, by other forms of empirical enquiry, including the human sciences.

Utilitarianism has an apparent pedigree when it comes to animal welfare. It supports the view that animal welfare matters just as much as human welfare. And many utilitarians support and oppose various practices in line with more mainstream concern over animal welfare, such as that we should not kill animals for food or other uses, and that we ought not to torture animals for fun. This relationship has come under tension from many directions. The aim of this article is to (...) add further considerations in support of that tension. I suggest three ways in which utilitarianism comes significantly apart from mainstream concerns with animal welfare. First, utilitarianism opposes animal cruelty only when it offers an inefficient ratio of pleasure to pain; while this may be true of eating animal products, it is not obviously true of other abuses. Second, utilitarianism faces a familiar problem of the inefficacy of individual decisions; I consider a common response to this worry, and offer further concerns. Finally, the common utilitarian argument against animal cruelty ignores various pleasures that humans may get from the superior status that a structure supporting exploitation confers. (shrink)

Although we are still in the dark when it comes to giving necessary and jointly sufficient criteria for what it takes to be thinking a singular thought, the paradigm cases are just ones where an agent is thinking about some particular object. When we erroneously think that Vulcan is a planet, our thought appears to be singular since it is, after all, about Vulcan. A promising way to explain this is to claim that there is something, a merely hypothetical entity, (...) that is Vulcan. There have been notable supporters for positing hypothetical entities for some time now, but the account of how we create hypothetical entities is still underdeveloped. In fact, we face a puzzle if we assume: hypothetical entities are created by us; we create a given hypothetical entity only when we falsely hypothesize something to be the unique F; we create the hypothetical entity long before we learn that there is no unique F. How can we possibly manage to conditionally and unknowingly create some entity when there is no unique F? In showing how this is possible, it will become clear that we have good reason for preferring a view that posits hypothetical entities over the alternative ways of accounting for our apparently singular thoughts about Vulcan, Pegasus, the Fountain of Youth, and so on.
