This book discusses a range of important issues in current philosophical work on the nature of possible worlds. Areas investigated include the theories of the nature of possible worlds, general questions about metaphysical analysis and questions about the direction of dependence between what is necessary or possible and what could be.

David Lewis's work is of fundamental importance in many areas of philosophical inquiry and there are few areas of Anglo-American philosophy where his impact has not been felt. Lewis's philosophy also has a rare unity: his views form a comprehensive philosophical system, answering a broad range of questions in metaphysics, philosophy of mind, philosophy of language, philosophy of action and many other areas. This breadth of Lewis's work, however, has meant that it is difficult to know where to start in (...) Lewis's work and a casual reader may often miss some of the illuminating connections between apparently quite disparate pieces of Lewis's work. This book aims to make this body of work more accessible to a general philosophical readership, while also providing a unified overview of the many contributions Lewis has made to contemporary Anglo-American philosophy. The book can be divided into four parts. The first part examines Lewis's metaphysical picture - one of the areas where he has had the greatest impact and also the framework for the rest of his theories. The second section discusses Lewis's important contributions in the philosophy of mind, language and meaning. The third part explores some of Lewis's work in decision theory, metaethics and applied ethics, areas where his work in not necessarily as widely appreciated, but in which he has done a range of work that is both accessible and important. The final section focuses on Lewis's distinctive philosophical method, perhaps one of his most significant legacies, which combines naturalism with "common-sense" theorizing. (shrink)

In this book, Daniel Patrick Kelly examines Kant's Critique of Pure Reason through the lens of historical contextualization and highlights the importance of Kant's "Transcendental Dialectic" in the greater justification of his overarching transcendental idealism.

The successful specification of the definition of art has so far proven elusive. Discouraged by repeated failed attempts at the definition of art, numerous anti-essentialist philosophers have suggested alternative accounts. In this paper I defend the project of the definition of art by arguing that the strongest anti-essentialist arguments are unsuccessful in ruling out either the possibility or the value of a definition of art. Based on my observations regarding a blind spot in Wittgenstein’s anti-essentialist “look and see” approach, I (...) conclude by suggesting a new avenue of investigation for essentialism regarding art.

In this study Daniel Lister assesses the radical critiques of state schooling in America and criticises reliance on functional explanations to articulate the connection between schools and society.

Christian Smith has described the religious attitudes of American youth and many adults as Moralistic Therapeutic Deism. In this formulation the word “therapeutic” does much work, and is meant to indicate that the goal of life is to be happy, to which end religion is instrumental. Martha Nussbaum has argued that Hellenistic schools of philosophy were therapeutic and instrumental in much the same way, and that this is a possible mode of philosophy even today. Appealing to the historical investigations of (...) Pierre Hadot and Giovanni Reale, this paper shows that Neoplatonism was an even more successful form of therapeutic philosophy, a fact which Augustine recognized and to which he responded in his therapeutic masterpiece Confessions, through his depiction of his mother as a sage. This suggests that Catholicism can be powerful when presented therapeutically, which might be a more appropriate mode for evangelism in our therapeutic age. (shrink)

The Cambridge History of Science, vol. 1, Ancient Science. Edited by Alexander Jones and Liba Taub. Cambridge: Cambridge University Press, 2018. Pp. xix + 642. $160.

This article takes stock of the seeming wealth of visual and material sources concerning stars and numbers that has come down to us from early imperial China (221 BCE–755 CE) and their minimal impact on how we write the history of astronomy and mathematics in this period. My goal is to offer ideas about how we might better engage with these sources and work across ancient and modern disciplines. I begin by outlining the conceptual categories into which our historical subjects (...) divided these sciences, followed by an overview of those visual and material sources we know from textual sources to have once existed versus those that are currently extant. The historiographic disconnect, I argue, is due in part to an inherent disconnect in the sources that have survived and, in some degree, to terminological and categorical confusion between those working in the history of science, divination, and art. Pointing to what are, in my opinion, good examples of how we might move forward and beyond the limits imposed by our sources and disciplinary boundaries, I then end on a list of questions I think fruitful to explore. What, for example, do we mean by “accuracy” when speaking of how constellations are represented in technical literature and tomb murals? (shrink)

The literature on conscience in medicine has paid little attention to what is meant by the word ‘conscience.’ This article distinguishes between retrospective and prospective conscience, distinguishes synderesis from conscience, and argues against intuitionist views of conscience. Conscience is defined as having two interrelated parts: (1) a commitment to morality itself; to acting and choosing morally according to the best of one’s ability, and (2) the activity of judging that an act one has done or about which one is deliberating (...) would violate that commitment. Tolerance is defined as mutual respect for conscience. A set of boundary conditions for justifiable respect for conscientious objection in medicine is proposed. (shrink)

For decades, physicians, philosophers, theologians, lawyers, and the public considered brain death a settled issue. However, a series of recent cases in which individuals were declared brain dead yet physiologically maintained for prolonged periods of time has challenged the status quo. This signals a need for deeper reflection and reexamination of the underlying philosophical, scientific, and clinical issues at stake in defining death. In this paper, I consider four levels of philosophical inquiry regarding death: the ontological basis, actual states of (...) affairs, epistemological standards, and clinical criteria for brain death. I outline several candidates for the states of affairs that may constitute death, arguing that we should strive for a single, unified ontological definition of death as a loss of integrated functioning as a unified organism, while acknowledging that two states of affairs may satisfy this concept. I argue that the clinical criteria for determining whole-brain death should be bolstered to meet the epistemic demand of sufficient certainty in defining death by adding indicators of cerebro-somatic dis-integration to the traditional triad of loss of consciousness, loss of brainstem function, and absence of confounding explanations.

Increasingly, physicians are being asked to provide technical services that many believe are morally wrong or inconsistent with their beliefs about the meaning and purposes of medicine. This controversy has sparked persistent debate over whether practitioners should be permitted to decline participation in a variety of legal practices, most notably physician-assisted suicide and abortion. These debates have become heavily politicized, and some of the key words and phrases are being used without a clear understanding of their meaning. In this essay, (...) I endeavor, firstly, to clarify the meaning of some of these terms: conscience, conscientious action, professional judgment, conscientious objection, conscience clauses, civil disobedience, and tolerance. I argue that use of the term conscientious objection to describe these refusals by health care professionals is mistaken and confusing. Secondly, relying on a proper understanding of the moral and technical character of medical judgment, the optimal deference that the state and markets ought to have toward professions, and general principles of Lockean tolerance for a diversity of practices and persons in a flourishing, pluralistic, democratic society, I offer a defense of tolerance with respect to the deeply held convictions of physicians and other health care professionals who hold minority views on contested but legal medical practices.

The word ‘dignity’ is used in a variety of ways in bioethics, and this ambiguity has led some to argue that the term must be expunged from the bioethical lexicon. Such a judgment is far too hasty, however. In this article, the various uses of the word are classified into three serviceable categories: intrinsic, attributed, and inflorescent dignity. It is then demonstrated that, logically and linguistically, the attributed and inflorescent meanings of the word presuppose the intrinsic meaning. Thus, one cannot (...) conclude that these meanings are arbitrary and unrelated. This categorization and logical and linguistic analysis helps to unravel what seem to be contradictions in discourse about dignity and bioethics, and provides a hierarchy of meaning that has potential normative implications.

Abstract:Arguments against physicians’ claims of a right to refuse to provide tests or treatments to patients based on conscientious objection often depend on two premises that are rarely made explicit. The first is that the protection of religious liberty (broadly construed) should be limited to freedom of worship, assembly, and belief. The second is that because professions are licensed by the state, any citizen who practices a licensed profession is required to provide all the goods and services determined by the (...) profession to fall within the scope of practice of that professional specialty and permitted by the state, regardless of any personal religious, philosophical, or moral objection. In this article, I argue that these premises ought to be rejected, and therefore the arguments that depend on them ought also to be rejected. The first premise is incompatible with Locke’s conception of tolerance, which recognizes that fundamental, self-identifying beliefs affect public as well as private acts and deserve a broad measure of tolerance. The second premise unduly (and unrealistically) narrows the discretionary space of professional practice to an extent that undermines the contributions professions ought to be permitted to make to the common good. Tolerance for conscientious objection in the public sphere of professional practice should not be unlimited, however, and the article proposes several commonsense, Lockean limits to tolerance for physician claims of conscientious objection.

One of the most important questions in the debate over the morality of euthanasia and assisted suicide is whether an important distinction between killing patients and allowing them to die exists. The U.S. Supreme Court, in rejecting challenges to the constitutionality of laws prohibiting physician-assisted suicide, explicitly invoked this distinction, but did not explicate or defend it. The Second Circuit of the U.S. Court of Appeals had previously asserted, also without argument, that no meaningful distinction exists between killing and allowing (...) to die. That court had reasoned that if this were so, it would be discriminatory to allow persons on life support to end their lives by removing such treatment, while those who are not connected to life support would be denied similar access to death.

A number of practices at the end of life can causally contribute to diminished consciousness in dying patients. Despite overlapping meanings and a confusing plethora of names in the published literature, this article distinguishes three types of clinically and ethically distinct practices: double-effect sedation, parsimonious direct sedation, and sedation to unconsciousness and death. After exploring the concept of suffering, the value of consciousness, the philosophy of therapy, the ethical importance of intention, and the rule of double effect, these three practices (...) are defined clearly and evaluated ethically. It is concluded that, if one is opposed to euthanasia and assisted suicide, double-effect sedation can frequently be ethically justified, that parsimonious direct sedation can be ethically justified only in extremely rare circumstances in which symptoms have already completely consumed the patient’s consciousness, and that sedation to unconsciousness and death is never justifiable. The special case of sedation for existential suffering is also considered and rejected. (shrink)

While there has been much discussion about the role of oaths in medical ethics, this discussion has previously centered on the content of various oaths. Little conceptual work has been done to clarify what an oath is, or to show how an oath differs from a promise or a code of ethics, or to explore what general role oath-taking by physicians might play in medical ethics. Oaths, like promises, are performative utterances. But oaths are generally characterized by their greater moral (...) weight compared with promises, their public character, their validation by transcendent appeal, the involvement of the personhood of the swearer, the prescription of consequences for failure to uphold their contents, the generality of the scope of their contents, the prolonged time frame of the commitment, the fact that their moral force remains binding in spite of failures on the part of those to whom the swearer makes the commitment, and the fact that interpersonal fidelity is the moral hallmark of the commitment of the swearer. Oaths are also distinct from codes. Codes are collections of specific moral rules. Codes are not performative utterances. They do not commit future intentions and do not involve the personhood of the one enjoined by the code. Recent attacks on oath-taking by physicians are discussed. Two arguments in favor of oath-taking are presented: one on the basis of the nature of medicine as a profession and the other on the basis of rule-utilitarian considerations. No attempt is made to define which oath a physician should swear. (shrink)

Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

The Rule of Double Effect has played an important role in bioethics, especially during the last fifty years. Its major application in bioethics has been in providing physicians who are opposed to euthanasia with a moral justification for using opioid analgesics in treating the pain of patients whose death might thereby be hastened. It has also prominently been applied to certain obstetric cases. The scope of application of double effect is actually much broader than medical ethics, extending to cover such (...) topics as strategic bombing in warfare. This article, while general in theory, concentrates on its applications in medical ethics. (shrink)

Pellegrino was there at the beginning of the field. In the 1950s and 60s, before there was a Kennedy Institute of Ethics or a Hastings Center; before the word ‘bioethics’ itself was coined, Pellegrino was writing articles such as "Ethical Considerations in the Practice of Medicine and Nursing," published in 1964. He was among those who started the Society for Health and Human Values—a precursor organization to the American Society for Bioethics and Humanities. He was the founding editor of the (...)

The notion of the value of life is often invoked in discussions regarding medical care for the sick and the dying. This theme has figured in arguments about medical ethics for decades, but many of the phrases associated with this concept have received little serious scrutiny. It is true that some philosophers have declared a few commonly used phrases such as “the sanctity of life,” “the infinite value of life,” and “the value of life itself” to be unclear at best (...) or misguided at worst. Their hasty dismissal of these phrases, however, is not the end of the story. I generally agree with this philosophical judgment but for reasons very different from those typically given by others. Moreover, the reasons I wish to .. (shrink)

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive (...) for diversity policies, we advise against interpreting such results overly broadly. (shrink)

The dead donor rule (DDR) originally stated that organ donors must not be killed by and for organ donation. Scholars later added the requirement that vital organs should not be procured before death. Some now argue that the DDR is breached in donation after circulatory determination of death (DCDD) programs. DCDD programs do not breach the original version of the DDR because vital organs are procured only after circulation has ceased permanently as a consequence of withdrawal of life-sustaining therapy. We (...) hold that the original rendition of the DDR banning killing by and for organ donation is the fundamental norm that should be maintained in transplantation ethics. We propose separating the DDR from two other fundamental normative rules: the duties to prevent harm and to obtain informed consent. (shrink)

Many states in the U.S. have adopted policies regarding human embryonic stem cell (hESC) research in the last few years. Some have arrived at these policies through legislative debate, some by referendum, and some by executive order. New York has chosen a unique structure for addressing policy decisions regarding this morally controversial issue by creating the Empire State Stem Cell Board with two Committees—an Ethics Committee and a Funding Committee. This essay explores the pros and cons of various policy arrangements (...) for making public policy decisions about morally controversial issues in bioethics (as well as other issues) through the lens of Deliberative Democracy, focusing on the principles of reciprocity, publicity, and accountability. Although New York's unique mechanism potentially offers an opportunity to make policy decisions regarding a morally controversial subject like hESC research in accord with the principles of Deliberative Democracy, this essay demonstrates its failure to do so in actual fact. A few relatively simple changes could make New York's program a real model for putting Deliberative Democracy into practice in making policy decisions regarding controversial bioethical issues.

Media coverage and statements by various Catholic spokespersons regarding the case of Terri Schiavo has generated enormous and deeply unfortunate confusion regarding Church teaching about the use of life-sustaining treatments. Two weeks ago, for example, I received a letter from the superior of a community of Missionary Sisters of Charity, who operate a hospice here in the United States The Missionary Sisters of Charity are the community founded by Mother Theresa, the 20th Century saint whose primary ministry was to rescue (...) dying Untouch-ables from the streets of Calcutta and bring them into her convent where they were washed, sheltered, fed if they were able to eat, prayed for, and cherished. In other words, the sisters gave these poor souls the gift of a death with dignity. The order Mother Theresa founded has continued this ministry, running hospices in the United States and elsewhere for the homeless, the destitute, those dying of AIDS and poverty and drug addiction, and all those dying alone and otherwise unwanted.

David Thomasma called for the development of a medical ethics based squarely on the philosophy of medicine. He recognized, however, that widespread anti-essentialism presented a significant barrier to such an approach. The aim of this article is to introduce a theory that challenges these anti-essentialist objections. The notion of natural kinds presents a modest form of essentialism that can serve as the basis for a foundationalist philosophy of medicine. The notion of a natural kind is neither static nor reductionistic. Disease (...) can be understood as making necessary reference to living natural kinds without invoking the claim that diseases themselves are natural kinds. The idea that natural kinds have a natural disposition to flourish as the kinds of things that they are provides a telos to which to tether the notion of disease – an objective telos that is broader than mere survival and narrower than subjective choice. It is argued that while nosology is descriptive and may have therapeutic implications, disease classification is fundamentally explanatory. Sickness and illness, while referring to the same state of affairs, can be distinguished from disease phenomenologically. Scientific and diagnostic fallibility in making judgments about diseases do not diminish the objectivity of this notion of disease. Diseases are things, not kinds. Injury is a concept parallel to disease that also makes necessary reference to living natural kinds. These ideas provide a new possibility for the development of a philosophy of medicine with implications for medical ethics. (shrink)

This article traces the history of the concept of dignity in Western thought, arguing that it became a formal Catholic theological concept only in the late nineteenth century. Three uses of the word are distinguished: intrinsic, attributed, and inflorescent dignity, of which, it is argued, the intrinsic conception is foundational. The moral norms associated with respect for intrinsic dignity are discussed briefly. The scriptural and theological bases for adopting the concept of dignity as a Christian idea are elucidated. The article (...) concludes by discussing the relevance of this concept of dignity to the spiritual and ethical care of the dying. (shrink)

We situate Henrich’s book in the larger research tradition of which it is a part and show how he presents a wide array of recent psychological, physiological, and neurological data as supporting the view that two related but distinct processes have shaped human nature and made us unique: cumulative cultural evolution and culture-driven genetic evolution. We briefly sketch out several ways philosophers might fruitfully engage with this view and note some implications it may have for current philosophic debates in moral (...) and political theory and over the nature of extended cognition. We end by noting how Henrich’s view of the source of cultural design and innovation, and the prominence of place he gives to the extended process of cultural evolution, cuts against a cluster of broad but common views about human minds, recasting putative bugs as features and indicating that many of the distinctive features of our individual minds evolved to allow them to be effective cogs in the larger, more productive cultural machine.

One major argument against prohibiting euthanasia and physician-assisted suicide (PAS) is that there is no rational basis for distinguishing between killing and allowing to die: if we permit patients to die by forgoing life-sustaining treatments, then we also ought to permit euthanasia and PAS. In this paper, the author argues, contra this claim, that it is in fact coherent to differentiate between killing and allowing to die. To develop this argument, the author provides an analysis of Saint Augustine’s distinction between (...) martyrdom and suicide, highlighting the relevance of intention in the assessment of an agent’s actions. As a general matter of ethics, the intentions of agents, not just the outcomes of their actions, matter enormously for drawing distinctions between what is permissible and what is impermissible. Constructing an Augustinian account of this distinction between killing and allowing to die, the author argues that it is coherent to hold that assisted suicide is wrong, while also accepting that it is permissible to withhold or withdraw life-sustaining treatments.

Recent years have witnessed a growing concern that terminally illpatients are needlessly suffering in the dying process. This has ledto demands that physicians become more attentive in the assessment ofsuffering and that they treat their patients as `whole persons.'' Forthe most part, these demands have not fallen on deaf ears. It is nowwidely accepted that the relief of suffering is one of the fundamentalgoals of medicine. Without question this is a positive development.However, while the importance of treating suffering has generally (...) beenacknowledged, insufficient attention has been paid to the question ofwhether different types of terminal suffering require differnt responsesfrom health care professionals. In this paper we introduce a distinctionbetween two types of suffering likely to be present at the end of life,and we argue that physicians must distinguish between these types if theyare to respond appropriately to the suffering of their terminally illpatients. After introducing this distinction and explaining its basis,we further argue that the distinction informs a (novel) principle ofproportionality, one that should guide physicians in balancing theircompeting obligations in responding to terminal suffering. As weexplain, this principle is justified by reference to the intereststerminally ill patients have in restoration, as well as in therelief of suffering, at the end of life. (shrink)

The word ‘dignity’ arises continuously in the debate over euthanasia and assisted suicide, both in Europe and in North America. Unlike the phrases ‘autonomy’ and ‘slippery slope’, ‘dignity’ is used by those on both sides of the question. For example, the organizations most prominently associated with the campaign that culminated in the recent legalization of euthanasia in Belgium are the Association pour la Droit de Mourir dans la Dignité and Recht op Waardig Sterven. Yet when Belgium passed its euthanasia law, (...) that nation’s Catholic bishops declared, “All this is opposed to the fundamental respect for human life that lies at the heart of a society based on human dignity”. Or, consider the fact that the legislation that legalized assisted suicide in the state of Oregon, U.S.A., was called the “Death with Dignity Act.” Yet opponents of assisted suicide in the United States, such as the Family Research Council, have declared that, “The idea of assisted suicide is a poison pill that kills the dignity of a precious human life”.Over and above differences in translation, the word ‘dignity’ cannot mean the same thing in all four of the preceding sentences. It cannot be the univocal basis of moral arguments both for and against euthanasia and assisted suicide. A better understanding of this word would therefore help to bring clarity and insight to the arguments about euthanasia and assisted suicide in Europe, North America, and throughout the world.

Virtue ethics seems to be a promising moral theory for understanding and interpreting the development and behavior of artificial moral agents. Virtuous artificial agents would blur traditional distinctions between different sorts of moral machines and could make a claim to membership in the moral community. Accordingly, we investigate the “machine question” by studying whether virtue or vice can be attributed to artificial intelligence; that is, are people willing to judge machines as possessing moral character? An experiment describes situations where either (...) human or AI agents engage in virtuous or vicious behavior and experiment participants then judge their level of virtue or vice. The scenarios represent different virtue ethics domains of truth, justice, fear, wealth, and honor. Quantitative and qualitative analyses show that moral attributions are weakened for AIs compared to humans, and the reasoning and explanations for the attributions are varied and more complex. On “relational” views of membership in the moral community, virtuous machines would indeed be included, even if they are indeed weakened. Hence, while our moral relationships with artificial agents may be of the same types, they may yet remain substantively different than our relationships to human beings. (shrink)
