Bernard Lonergan has argued for a theory of cognition that is transcendentally secure, that is, one such that any plausible attempt to refute it must presuppose its correctness, and one that also grounds a correct metaphysics and ontology. His proposal combines an identity theory of knowledge with an intentional relation between knower and known. It depends in a crucial way upon an appropriation of one’s own cognitional motives and acts, that is, upon “knowing one’s own knowing.” I argue that because (...) of conflicts between the identity and intentionality components of the theory, rational self-appropriation cannot, as Lonergan claims, be an iteration of just the same acts by which we acquire other sorts of knowledge. I propose an amended theory in which the relation between intending-subject and intended-object of first-level cognition becomes, in RSA, a numerical identity of knower and known and of the epistemic and the ontological.

This note calls attention to the fact that efficient causes – the sort of cause that changes something or makes something happen – can play no constitutive role in the immediate, cognitively conscious relation between cognitive subject and a cognit-ive object. It notes that: (1) it is a necessary condition for an efficient causal relation that it alter its relata; and (2) it is a necessary condition for a conscious cognitive relat-ion that it does not alter its relata. This has (...) important implication for the theories of knowledge and consciousness, the “Hard Problem,” and related puzzles. (shrink)

In this paper I argue that Bonjour’s claim that empirical beliefs can only be justified by other empirical beliefs and his use of non-normative “spontaneous empirical beliefs” and the “The Doxastic Preumption” fail to solve the problems of coherence theory. I propose a justification of empirical (and other beliefs) based on the work of B. Lonergan.

David Chalmers argues that consciousness -- authentic, first-person, conscious consciousness -- cannot be reduced to brain events or to any physical event, and that efforts to find a workable mind-body identity theory are, therefore, doomed in principle. But for Chalmers and non-reductionist in general consciousness consists exclusively, or at least paradigmatically, of phenomenal or qualia-consciousness. This results in a seriously inadequate understanding both of consciousness and of the “hard problem.” I describe other, higher-order cognitional events which must be conscious if (...) the “hard problem” is to be solved -- in any sense of ‘solve’ which would make us any the wiser about it -- but whose consciousness is quite different from the qualia and phenomena usually inventoried. Events of this kind are both part of the hard problem and the means by which we will solve it, if we ever do. (shrink)

In this paper I call attention to the fact that Lonergan gives two radically opposed accounts of how sense perception relates us to the external world and of how we know that this relation exists. I argue that the position that Lonergan characteristically adopts is not the one implied by what is most fundamental in his theory of cognition. I describe the initial epistemic position with regard to the problem of skepticism about the external material world that is in fact (...) implied by his theory of cognition, and I sort out some confusion about various forms of direct and representative perceptual realism. The paper concludes with a critique of Lonergan’s theory of description and explanation in empirical science that makes evident the difficulties into which he is led by lack of clarity in his theory of perception.

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)

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.

Some philosophers and disability advocates argue that disability is not bad for you. Rather than treated as a harm, it should be considered and even celebrated as just another manifestation of human diversity. Disability is mere difference.

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)

In 1969 Stanley Cavell's Must We Mean What We Say? revolutionized philosophy of ordinary language, aesthetics, ethics, tragedy, literature, music, art criticism, and modernism. This volume of new essays offers a multi-faceted exploration of Cavell's first and most important book, fifty years after its publication. The key subjects which animate Cavell's book are explored in detail: ordinary language, aesthetics, modernism, skepticism, forms of life, philosophy and literature, tragedy and the self, the questions of voice and audience, jazz and sound, Wittgenstein, (...) Austin, Beckett, Kierkegaard, Shakespeare. The essays make Cavell's complex style and sometimes difficult thought accessible to a new generation of students and scholars. They offer a way into Cavell's unique philosophical voice, conveying its seminal importance as an intellectual intervention in American thought and culture, and showing how its philosophical radicality remains of lasting significance for contemporary philosophy, American philosophy, literary studies, and cultural studies.

The author offers an accessible, non-dogmatic guide to sharing secrets of the Direct Path that are rarely revealed. 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.

This book argues that peace must be a public thing. Philosophers of peace have long worked for public results. Opposing nuclear weapons, organizing the disinherited, challenging violence in the status quo, such are the legacies of engaged philosophers. Our authors remember these examples as we confront modern challenges such as immigration, police interrogation, or mental health.

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)

To a world assaulted by private interests, this book argues that peace must be a public thing. Distinguished philosophers of peace have always worked publicly for public results. Opposing nuclear proliferation, organizing communities of the disinherited, challenging violence within status quo establishments, such are the legacies of truly engaged philosophers of peace. This volume remembers those legacies, reviews the promise of critical thinking for crises today, and expands the free range of thinking needed to create more mindful and peaceful relations. (...) With essays by committed peace philosophers, this volume shows how public engagement has been a significant feature of peace philosophers such as Camus, Sartre, Dewey, and Dorothy Day. Today we also confront historical opportunities to transform practices for immigration, police interrogation, and mental health, as we seek to sustain democracies of increasing multicultural diversity. In such cases our authors consider points of view developed by renowned thinkers such as Weil, Mouffe, Conway, and Martín-Baró. This volume also presents critical analysis of concepts for thinking about violence, reconsiders Plato’s philosophy of justice, and examines the role of ethical theory for liberation struggles such as Occupy!

This chapter explores how the dialectical approaches by Mao Zedong and Martin Luther King, Jr., may assist philosophical analysis of nonviolent social change applied to achievement of economic justice and positive peace in this life. “Martin and Mao” are both interested in the theoretical and practical problems of creating conditions for a world where economic justice and positive peace may be pursued from within dialectical processes that are, in Mao’s words, “non-antagonistic.” The dialectical logics of Mao and King reveal a (...) convergence upon the claim that contradictions with antagonistic aspects can and should be transformed into non-antagonistic ones. Both philosophers value unity as an end, and both argue that our conceptions of purpose must aim toward a world where practical conditions of unity are taken seriously. Therefore, we must aim toward economic justice and posisdtive peace. (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.

Cost effectiveness analysis is a tool for evaluating the aggregate benefits of medical treatments, health care services, and public health programs.

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)
