The prospect of using cell-based interventions (CBIs) to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such changes, although perhaps remote, is cause for concern and careful ethical analysis. Both to enable better informed consent in the future and as an end in itself, we argue that early human trials of CBIs for neurological conditions must monitor subjects for changes in cognition, mood, and behavior; further, we recommend concrete steps for that monitoring. Such steps will help better characterize the potential risks and benefits of CBIs as they are tested and potentially used for treatment.

The prospect of using memory modifying technologies raises interesting and important normative concerns. We first point out that those developing desirable memory modifying technologies should keep in mind certain technical and user-limitation issues. We next discuss certain normative issues that the use of these technologies can raise such as truthfulness, appropriate moral reaction, self-knowledge, agency, and moral obligations. Finally, we propose that as long as individuals using these technologies do not harm others and themselves in certain ways, and as long as there is no prima facie duty to retain particular memories, it is up to individuals to determine the permissibility of particular uses of these technologies.

Anthropogenic climate change is arguably one of the biggest problems that confront us today. There is ample evidence that climate change is likely to affect adversely many aspects of life for all people around the world, and that existing solutions such as geoengineering might be too risky and ordinary behavioural and market solutions might not be sufficient to mitigate climate change. In this paper, we consider a new kind of solution to climate change, what we call human engineering, which involves biomedical modifications of humans so that they can mitigate and/or adapt to climate change. We argue that human engineering is potentially less risky than geoengineering and that it could help behavioural and market solutions succeed in mitigating climate change. We also consider some possible ethical concerns regarding human engineering such as its safety, the implications of human engineering for our children and society, and we argue that these concerns can be addressed. Our upshot is that human engineering deserves further consideration in the debate about climate change

It is increasingly common for bioethicists to consult with the public to solicit their judgments and attitudes about ethical questions and issues, especially ones that arise with new and emerging technologies. However, it is not always clear what the purpose of this engagement is or ought to be: do bioethicists seek the input of the public to help them arrive at a morally correct justified policy position, or do they seek this input to help them shape and frame their already-established moral position, or something else entirely? In this essay, we discuss four distinct possible functions of collecting moral judgments from the public: issue spotting, messaging for adherence and social stability, substantive moral guidance, and procedural fairness. For each function, we offer core examples from the literature before discussing the strengths and weaknesses attendant to each. We conclude with several preliminary questions bioethicists can ask themselves to clarify their own purpose for soliciting moral judgments from the public.

In some views, philosophy’s glory days in bioethics are over. While philosophers were especially important in the early days of the field, so the argument goes, the majority of the work in bioethics today involves the “simple” application of existing philosophical principles or concepts, as well as empirical work in bioethics. Here, we address this view head on and ask: What is the role of philosophy in bioethics today? This paper has three specific aims: (1) to respond to skeptics and make the case that philosophy and philosophers still have a very important and meaningful role to play in contemporary bioethics, (2) to discuss some of the current challenges to the meaningful integration of philosophy and bioethics, and (3) to make suggestions for what needs to happen in order for the two fields to stay richly connected. We outline how bioethics center directors, funders, and philosopher bioethicists can help.

Parents and physicians often grapple with the agonizing decision of whether to continue life-sustaining treatment for critically ill infants. In this paper, we introduce a novel framework called the Fundamental Conditions Approach (FCA) to guide these difficult choices. Building on S. Matthew Liao’s work, the FCA evaluates whether an infant possesses or can develop the fundamental capacities necessary for engaging in basic activities that constitute a good life. These capacities include the ability to think, respond to facts, develop interpersonal relationships, and interact with one’ environment. We argue that if an infant lacks nearly all of these fundamental capacities and medical interventions cannot restore them, there are stronger ethical grounds for withdrawing life-sustaining treatment. Conversely, if an infant retains some fundamental capacities or could develop them with treatment, there are compelling reasons to continue care. To illustrate its practical and ethical implications, we apply the FCA to complex cases such as Tinslee Lewis and other infants with severe congenital conditions. We also compare the FCA with other prevailing models, including the best interest standard, the Life Worth Living Approach, the relational potential standard, and medical vitalism. We contend that the FCA offers more concrete guidance while avoiding some of the limitations inherent in these alternatives. While the FCA cannot eliminate all uncertainty in these challenging situations, we conclude that it provides a substantive and intuitively plausible approach to decision-making about life sustaining treatment for critically ill infants.

This chapter examines the issue of who has the duty to love a child, supposing that there is a right to be loved. It makes the striking claim that everyone has this duty, even when the biological parents are available. It explains that everyone’s having this duty does not mean that everyone has to do the same thing, and that biological parents should be given the status of primary dutybearers while others have associate duties to assist the primary dutybearers in carrying out this duty. This chapter also considers how demanding the duty to love a child should be and it argues that while there are limits as to how much we are required to sacrifice to fulfill this duty, we may be required to sacrifice more than what common sense morality supposes.

The book’s introduction points out that many international declarations claim that children have a right to be loved, but that philosophically speaking, there are a number of reasons to question whether there is in fact such a right. The introduction then lays out a plan to show that children have a right to be loved by answering questions such as whether children can have rights, what grounds the right to be loved, whether love is an appropriate object of a right, who has the corresponding duty to love a child, how demanding the duty to love should be, whether biological parenting should be licensed, and whether there is a duty to adopt those children who do not have adequate parents.

To a lay audience, it might seem surprising that it has to be shown that children are rightholders, since, for instance, the Universal Declaration of Human Rights explicitly states that “all human beings are born free and equal in dignity and rights,” which would seem to include children as rightholders. However, the claim that all human beings are rightholders is in fact surprisingly difficult to defend. When philosophers try to explain how all human beings are rightholders, they end up adopting what Peter Singer calls a “speciesist” position, where speciesism is defined as morally favoring a particular species—in this case, human beings—over others without sufficient justification. This chapter develops the “genetic basis for moral agency” account of rightholding and explains how this account can allow all human beings, including very young children, to be rightholders without being speciesist.

This chapter explores the topic of whether we should institute some kind of parental licensing scheme, that is, require biological parents to demonstrate certain competence and character before they are permitted to parent their biological children. Existing concerns regarding parental licensing tend to be practical concerns such as whether there can be a reliable way of determining who is a competent parent and whether the parental licensing scheme can be enforced. These practical concerns leave open the possibility that parental licensing is theoretically correct. This chapter presents a new, theoretical case against parental licensing. In particular, it is argued that biological parenting should not be licensed because biological parenting is a fundamental right and fundamental rights should not be licensed.

This chapter addresses a number of objections against the possibility of a duty to love. Some people believe that a duty to love is an absurdity because duty requires that one can command the action required by the duty, but love is an emotion and is therefore not commandable. This chapter argues that in fact love is commandable even if it is an emotion. This chapter also responds to the concern that really to love a person, we must be motivated to do so for the person’s sake, but to have a duty to love a person means that we would not be motivated to love the person for the person’s sake but for the sake of the duty; and the concern that someone may behave as if he loves a child when in fact he does not in order to satisfy the duty to love.

This chapter first considers how the right to be loved should be prioritized. It argues that even if children’s being loved is not as urgent as, for instance, being fed, it is still very urgent; that governments do not give absolute priority to whatever is most necessary for action; and that to develop institutional arrangements that can adequately provide for children’s various fundamental conditions, it is important to take into account all of their fundamental conditions, including their need for love. This chapter then draws the book to a close by pointing out that the proclamation that children have a right to be loved is not merely empty rhetoric and that in fact this right can be justified in the same way as other rights.

This chapter argues that there is a duty to adopt many of the children without adequate parents, and that we can derive this duty straightforwardly from the right of children to be loved. It first considers and rejects the Easy Rescue view, according to which those who want to have children have a duty to adopt rather than have biological children, because, among other things, the cost of adoption will not be much more than the cost of having a biological child. It then defends the Human Right view, according to which the duty to adopt belongs to every able person in appropriate circumstances. This chapter concludes by proposing a potential way of encouraging more people who are motivated to adopt actually to adopt.

That children need to be loved is a claim that many people would find intuitive and obvious. However, some people have questioned this claimed. Psychologists have long theorized about the importance of early relationships for all aspects of children’s later development. Drawing on their theories, this chapter offers some theoretical explanations of why being loved is a fundamental condition for children to pursue a good life—that is, why children need to be loved. In addition, there is a vast array of ongoing scientific research devoted toward understanding why children need to be loved, both at the psychological level and at the biological level. To further support the claim that children need to be loved, this chapter presents some of the key findings and details some of the latest results from this research.

Bioethics is the study of ethical issues arising out of advances in the life sciences and medicine. Historically, bioethics has been associated with issues in research ethics and clinical ethics as a result of research scandals such as the Tuskegee Syphilis Study and public debates about the definition of death, medical paternalism, health care rationing, and abortion. As biomedical technologies have advanced, challenging new questions have arisen for bioethics and new sub-disciplines such as neuroethics and public health ethics have entered the scene. This volume features ten original essays on five cutting-edge controversies in bioethics written by leading philosophers. I. Research Ethics: How Should We Justify Ancillary Care Duties? II. Clinical Ethics: Are Psychopaths Morally Accountable? III. Reproductive Ethics: Is There A Solution to the Non-Identity Problem? IV. Neuroethics: What is Addiction and Does It Excuse? V. Public Health Ethics: Is Luck Egalitarianism Implausibly Harsh? S. Matthew Liao and Collin O’Neil’s concise introduction to the essays in the volume, the annotated bibliographies and study questions for each controversy, and the supplemental guide to additional current controversies in bioethics give the reader a broad grasp of the different kinds of challenges in bioethics.

The introduction introduces the history of the concept of human rights and its philosophical genealogy. It raises questions of the nature of human rights, the grounds of human rights, difference between proposed and actual human rights, and scepticism surrounding the very idea of human rights. In the course of this discussion, it concludes that the diversity of positions on human rights is a sign of the intellectual, cultural, and political fertility of the notion of human rights. The chapter concludes with an overview of the chapters present in the volume.

Scanlon’s book aims to offer us a moral theory of right and wrong and of our obligations to one another. The theory is called contractualism and its central claim is that an act is right or wrong if and only if it could or could not be justified to others on grounds that they could not reasonably reject (p. 4). Scanlon recognizes that so stated, his contractualism might seem empty in the sense that one might think that the aim of offering grounds that others could not reasonably reject is an aim to which all plausible moral theories would aspire (p. 4). For example, as Scanlon himself acknowledges, utilitarians, who hold the view that an act is right only if it would produce the greatest happiness, presumably would believe that their view is one that no reasonable person could possibly reject (p. 189). However, Scanlon believes that his contractualism is in fact substantive. According to Scanlon, his contractualism holds the process of justifying to others to be ‘basic’ (p. 5). In other words, Scanlon believes that simply by thinking about what could be justified to others on grounds that they could not reasonably reject, we can ‘determine the shape of more specific moral notions such as murder or betrayal (p. 5).’ As Scanlon explains, even though utilitarians may also accept that an act is right if and only if it can be justified to others, what makes an action right for utilitarians is that the action has the best consequences; ‘justifiability is merely a consequence of this’ (p. 189); whereas for Scanlon’s contractualism, justifiability is what makes an action right or wrong. The aim of Scanlon’s book is to elaborate and explicate this account of contractualism.

Limited Aggregation is the view that when there are competing moral claims that demand our attention, we should sometimes satisfy the largest aggregate of claims, depending on the strength of the claims in question. In recent years, philosophers such as Patrick Tomlin and Alastair Norcross have argued that Limited Aggregation violates a number of rational choice principles such as Transitivity, Separability, and Contraction Consistency. Current versions of Limited Aggregation are what may be called Comparative Approaches because they involve assessing the relative strengths of various claims. In this paper, we offer a non-comparative version of Limited Aggregation, what we call the Threshold Approach. It states that there is a non-relative threshold that separates various claims. We demonstrate that the Threshold Approach does not violate rational choice principles such as Transitivity, Separability, and Contraction Consistency, and we show that potential concerns regarding such a view are surmountable.

"Featuring seventeen original essays on the ethics of Artificial Intelligence by some of the most prominent AI scientists and academic philosophers today, this volume represents the state-of-the-art thinking in this fast-growing field and highlights some of the central themes in AI and morality such as how to build ethics into AI, how to address mass unemployment as a result of automation, how to avoiding designing AI systems that perpetuate existing biases, and how to determine whether an AI is conscious. As AI technologies progress, questions about the ethics of AI, in both the near-future and the long-term, become more pressing than ever. Should a self-driving car prioritize the lives of the passengers over the lives of pedestrians? Should we as a society develop autonomous weapon systems that are capable of identifying and attacking a target without human intervention? What happens when AIs become smarter and more capable than us? Could they have greater than human moral status? Can we prevent superintelligent AIs from harming us or causing our extinction? At a critical time in this fast-moving debate, thirty leading academics and researchers at the forefront of AI technology development come together to explore these existential questions, including Aaron James, Allan Dafoe, Andrea Loreggia, Andrew Critch, Azim Shariff, Carrick Flynn, Cathy O'Neil, Eliezer Yudkowsky, Eric Schwitzgebel, Frances Kamm, Francesca Rossi, Hanna Gunn, Iyad Rahwan, Jessica Taylor, JF Bonnefon, K. Brent Venable, Kate Devlin, Mara Garza, Nicholas Mattei, Nick Bostrom, Patrick LaVictoire, Peter Asaro, Peter Railton, S.

In the last fifteen years, there has been significant interest in studying the brain structures involved in moral judgments using novel techniques from neuroscience such as functional magnetic resonance imaging. Many people, including a number of philosophers, believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. This has led to a flurry of scientific and philosophical activities, resulting in the rapid growth of the new field of moral neuroscience. There is now a vast array of ongoing scientific research devoted towards understanding the neural correlates of moral judgments, accompanied by a large philosophical literature aimed at interpreting and examining the methodology and the results of this research. This is the first volume to take stock of fifteen years of research of this fast-growing field of moral neuroscience and to recommend future directions for research. It features the most up-to-date research in this area, and it presents a wide variety of perspectives on this topic.

S. Matthew Liao argues here that children have a right to be loved. To do so he investigates questions such as whether children are rightholders; what grounds a child's right to beloved; whether love is an appropriate object of a right; and other philosophical and practical issues. His proposal is that all human beings have rights to the fundamental conditions for pursuing a good life; therefore, as human beings, children have human rights to the fundamental conditions for pursuing a good life. Since being loved is one of those fundamental conditions, children thus have a right to be loved. Liao shows that this claim need not be merely empty rhetoric, and that the arguments for this right can hang together as a coherent whole. This is the first book to make a sustained philosophical case for the right of children to be loved. It makes a unique contribution to the fast-growing literature on family ethics, in particular, on children's rights and parental rights and responsibilities, and to the emerging field of the philosophy of human rights.
