This volume concerns the status and ambitions of metaphysics as a discipline.

This chapter examines the pioneering work of Gottfried Wilhelm Leibniz (1646-1716) on various number systems, in particular binary, which he independently invented in the mid-to-late 1670s, and hexadecimal, which he invented in 1679. The chapter begins with the oft-debated question of who may have influenced Leibniz’s invention of binary, though as none of the proposed candidates is plausible I suggest a different hypothesis, that Leibniz initially developed binary notation as a tool to assist his investigations in mathematical problems that were (...) exercising him at the time, namely those concerning the divisibility of composite numbers, primality, and perfect numbers. The chapter then explores Leibniz’s development of binary, his little-known work on binary fractions and expansions, his use of binary as a symbol for creation in his philosophical-theology, and his response to the suggestion that there was a correlation between binary numeration and the hexagrams of the ancient Chinese divinatory text, the Yijing. The chapter then focuses on Leibniz’s work on other number systems, in particular his invention and exploration of hexadecimal as well as his work on duodecimal. The chapter concludes by revealing a hitherto unknown practical application of binary that Leibniz devised in the last year of his life. (shrink)

What is the relation between a clay statue andthe lump of clay from which it is made? According to the defender of the standardaccount, the statue and the lump are distinct,enduring objects that share the same spatiallocation whenever they both exist. Suchobjects also seem to share the samemicrophysical structure whenever they bothexist. This leads to the standard objection tothe standard account: if the statue and thelump of clay have the same microphysicalstructure whenever they both exist, how canthey differ in their (...) de re temporalproperties, de re modal properties and soon? In this paper I develop amereological answer to this question – thestatue and the lump differ with respect totheir parts and this explains theirdifference with respect to de re temporalproperties, de re modal properties andthe like.

What is the best question to ask an omniscient being? The question is intriguing; is it also paradoxical? We discuss several versions of what Ned Markosian calls the paradox of the question and suggest solutions to each of those puzzles. We then offer some practical advice about what do if you ever have the opportunity to query an omniscient being.

This paper critically engages ethical issues in the allocation of novel, and potentially costly, health care resources to patients with disorders of consciousness. First, we review potential benefits of novel health care resources for patients and their families and outline preliminary considerations to address concerns about cost. We then address two problems regarding the allocation of health care resources to patients with disorders of consciousness: (1) the problem of uncertain moral status; and (2) the problem of accurately measuring the welfare (...) burdens these resources would relieve. We conclude by suggesting that opportunity-based frameworks might complement standard approaches for justifying resources allocation to patients with disorders of consciousness. (shrink)

In this book, S. A. Lloyd offers a radically new interpretation of Hobbes's laws of nature, revealing them to be not egoistic precepts of personal prudence but rather moral instructions for obtaining the common good.

African American distrust of medicine has consequences for treatment seeking and healthcare behaviour. Much work has been done to examine acute events that have contributed to this phenomenon and a sophisticated bioethics discipline keeps watch on current practices by medicine. But physicians and clinicians are not the only actors in the medical arena, particularly when it comes to health beliefs and distrust of medicine. The purpose of this paper is to call attention not just to ethical shortcomings of the past, (...) but to the structural contexts of those events and the contributions and responsibilities of popular media and academic disciplines in the production of knowledge. We argue that ignoring context and producing inaccurate work has real impacts on health and healthcare, particularly for African Americans, and thus engenders ethical obligations incumbent on disciplines traditionally recognised as purely academic.

This article asks whether personal ventilators should be redistributed to maximize lives saved in emergency condition, like the COVID-19 pandemic. It begins by examining extant claims that items like ventilators are literally parts of their user’s bodies. Arguments in favor of incorporation for ventilators fail to show that they meet valid sufficient conditions to be body parts, but arguments against incorporation also fail to show that they fail to meet clearly valid necessary conditions. Further progress on this issue awaits clarification (...) of difficult normative, conceptual, and metaphysical questions about the possible boundaries of a person’s body. Rather than relying solely on incorporation arguments, we propose an argument against reallocation from widely accepted anti-discrimination principles. Possession of a personal ventilator is an obvious marker of disability identity; thus, reallocating ventilators from those that already possess them discriminates on the basis of a stigmatized trait – a paradigm case of presumptively wrongful discrimination. This discrimination claim, taken together with uncertainty about the bodily status of ventilators, yields a strong presumption against personal ventilator reallocation. (shrink)

While procreation is ubiquitous, attention to the ethical issues involved in creating children is relatively rare. In Debating Procreation, David Benatar and David Wasserman take opposing views on this important question. David Benatar argues for the anti-natalist view that it is always wrong to bring new people into existence. He argues that coming into existence is always a serious harm and that even if it were not always so, the risk of serious harm is sufficiently great to make procreation (...) wrong. In addition to these "philanthropic" arguments, he advances the "misanthropic" one that because humans are so defective and cause vast amounts of harm, it is wrong to create more of them.David Wasserman defends procreation against the anti-natalist challenge. He outlines a variety of moderate pro-natalist positions, which all see procreation as often permissible but never required. After criticizing the main anti-natalist arguments, he reviews those pronatalist positions. He argues that constraints on procreation are best understood in terms of the role morality of prospective parents, considers different views of that role morality, and argues for one that imposes only limited constraints based on the well-being of the future child. He then argues that the expected good of a future child and of the parent-child relationship can provide a strong justification for procreation in the face of expected adversities without giving individuals any moral reason to procreate.

In coming decades, fetal medicine may become a routine part of reproductive care. The measures pregnant women now take to protect fetal health are largely generic, like restricting their diets and using supplements. Relatively few interventions are based on specific conditions revealed by ultrasound or genetic testing. A recent finding, though, may herald a dramatic rise in “personalized” fetal medicine: certain drugs already approved by the Food and Drug Administration can apparently boost neural growth in fetuses with Down syndrome, improving (...) cognitive functioning in the future child. Many more condition‐specific findings are likely in the near future. But as commentators have frequently observed about prenatal testing, technologies that appear to increase reproductive options also complicate and constrain them. (shrink)

We are gratified by Nelson's response to our commentary. It shows, for the first time, an appreciation of the distinctive character of our criticism of individual decisions to test and terminate for fetal impairment. Although we still find much to disagree with in Nelson's characterization and critique of our views, he has given us a welcome opportunity to clarify and develop them.

Assume that, even with a time machine, Tim does not have the ability to travel to the past and kill Grandfather. Why would that be? And what are the implications for traditional debates about freedom? We argue that there are at least two satisfactory explanations for why Tim cannot kill Grandfather. First, if an agent’s behavior at time _t_ is causally dependent on fact _F_, then the agent cannot perform an action (at _t_) that would require _F_ to have not (...) obtained. Second, if an agent’s behavior at time _t_ is causally dependent on fact _F_, then the agent cannot perform an action (at _t_) that would prevent _F_ from obtaining. These two explanations have distinct upshots for more traditional debates over freedom. The first implies that causal determinism is incompatible with the ability to do otherwise and also raises questions about the traditional arguments for the incompatibility of divine foreknowledge and the ability to do otherwise; the second does neither. However, both explanations imply that the Molinist account of divine providence renders agents unable to do otherwise, at least in certain circumstances. (shrink)

Analyses of dispositional ascriptions in terms of conditional statements famously confront the problems of finks and masks. We argue that conditional analyses of dispositions, even those tailored to avoid finks and masks, face five further problems. These are the problems of: (i) Achilles' heels, (ii) accidental closeness, (iii) comparatives, (iv) explaining context sensitivity, and (v) absent stimulus conditions. We conclude by offering a proposal that avoids all seven of these problems.

Disability and enhancement are often treated as opposing concepts. To become disabled in some respect is to move away from those who are enhanced in that same respect; to become enhanced is to move away from the corresponding state of disability. This chapter examines how best to understand the concepts of disability and enhancement in this symmetrical way. After considering various candidates, two types of accounts are identified as the most promising: welfarist accounts and typical-functioning accounts. The authors ultimately defend (...) a complex typical-functioning account as the best way to achieve a symmetrical understanding of disability and enhancement. (shrink)

I describe an ethic for business administration based on the social tradition of the Catholic Church. I find that much current thinking about business falters for its conceit of truth. Abstractions such as the shareholder-value model contain truth - namely, that business is an economic enterprise to manage for the wealth of its owners. But, as in all abstractions, this truth comes at the expense of falsehood -namely, that persons are assets to deploy on behalf of owners. This last is (...) "wrong" in both senses of the word - it is factually wrong in that persons are far more than business assets, they are supernatural beings, children of God; and it is morally wrong in that it is an injustice to treat them as the former when they are the latter. I draw upon the social tradition of the Catholic Church to recognize that the business of business is not business, but is instead the human person. Following Church teachings, I describe a person-centered ethic of business based upon eight social principles that both correct and enlarge the shareholder-centered ethic of much current business thinking. I discuss implications of this person-centered ethic for business administration. (shrink)

Noninvasive, prenatal whole genome sequencing may be a technological reality in the near future, making available a vast array of genetic information early in pregnancy at no risk to the fetus or mother. Many worry that the timing, safety, and ease of the test will lead to informational overload and reproductive consumerism. The prevailing response among commentators has been to restrict conditions eligible for testing based on medical severity, which imposes disputed value judgments and devalues those living with eligible conditions. (...) To avoid these difficulties, we propose an unrestricted testing policy, under which prospective parents could obtain information on any variant of known significance after a careful informed consent process that uses an interactive decision aid to deliver a mandatory presentation on the purposes, techniques, and limitations of genomic testing, as well as optional resources for reflection and consultation. This process would encourage thoughtful, informed deliberation... (shrink)

Previous theories of the relationship between dispositions and conditionals are unable to account for the fact that dispositions come in degrees. We propose a fix for this problem that has the added benefit of avoiding the classic problems of finks and masks.

Disability raises profound and fundamental issues: questions about human embodiment and well-being; dignity, respect, justice and equality; personal and social identity. It raises pressing questions for educational, health, reproductive, and technology policy, and confronts the scope and direction of the human and civil rights movements. Yet it is only recently that disability has become the subject of the sustained and rigorous philosophical inquiry that it deserves. The Oxford Handbook of Philosophy and Disability is the first comprehensive volume on the subject. (...) The volume's contents range from debates over the definition of disability to the challenges posed by disability for justice and dignity; from the relevance of disability for respect, other interpersonal attitudes, and intimate relationships to its significance for health policy, biotechnology, and human enhancement; from the ways that disability scholarship can enrich moral and political philosophy, to the importance of physical and intellectual disabilities for the philosophy of mind and action. The contributions reflect the variety of areas of expertise, intellectual orientations, and personal backgrounds of their authors. Some are founding philosophers of disability; others are promising new scholars; still others are leading philosophers from other areas writing on disability for the first time. Many have disabilities themselves. This volume boldly explores neglected issues, offers fresh perspectives on familiar ones, and ultimately expands philosophy's boundaries. More than merely presenting an overview of existing work, this Handbook will chart the growth and direction of a vital and burgeoning field for years to come. (shrink)

New fetal therapies offer important prospects for improving health. However, having to consider both the fetus and the pregnant woman makes the risk–benefit analysis of fetal therapy trials challenging. Regulatory guidance is limited, and proposed ethical frameworks are overly restrictive or permissive. We propose a new ethical framework for fetal therapy research. First, we argue that considering only biomedical benefits fails to capture all relevant interests. Thus, we endorse expanding the considered benefits to include evidence-based psychosocial effects of fetal therapies. (...) Second, we reject the commonly proposed categorical risk and/or benefit thresholds for assessing fetal therapy research. Instead, we propose that the individual risks for the pregnant woman and the fetus should be justified by the benefits for them and the study’s social value. Studies that meet this overall proportionality criterion but have mildly unfavorable risk–benefit ratios for pregnant women and/or fetuses may be acceptable. (shrink)

Frege's scathing comments on Mill on the empirical grounds of arithmetical truth are elaborated. The suggestion is made that some entities are ‘well-behaved' : if you perform two acts and then two more, the ‘result' will be that exactly four acts have occurred. How much it all matters or means is not further discussed.

How should we respond to individuals with disabilities? What does it mean to be disabled? Over fifty million Americans, from neonates to the fragile elderly, are disabled. Some people say they have the right to full social participation, while others repudiate such claims as delusive or dangerous. In this compelling book, three experts in ethics, medicine, and the law address pressing disability questions in bioethics and public policy. Anita Silvers, David Wasserman, and Mary B. Mahowald test important theories of (...) justice by bringing them to bear on subjects of concern in a wide variety of disciplines dealing with disability. They do so in the light of recent advances in feminist, minority, and cultural studies, and of the groundbreaking Americans with Disabilities Act. (shrink)
