Models of recognition memory have traditionally struggled with the puzzle of criterion setting, a problem that is particularly acute in cases in which items for study and test are of widely varying types, with differing degrees of baseline familiarity and experience (e.g., words vs. random dot patterns). We present a dynamic model of the recognition process that addresses the criterion setting problem and produces joint predictions for choice and reaction time. In this model, recognition decisions are based not on the (...) absolute value of familiarity, but on how familiarity changes over time as features are sampled from the test item. Decisions are the outcome of a race between two parallel accumulators: one that accumulates positive changes in familiarity (leading to an ‘‘old’’ decision) and another that accumulates negative changes (leading to a ‘‘new’’ decision). Simulations with this model make realistic predictions for recognition performance and latency regardless of the baseline familiarity of study and test items. (shrink)

This commentary argues against the indictment of current experimental practices such as piecemeal testing, and the proposed integrated experiment design (IED) approach, which we see as yet another attempt at automating scientific thinking. We identify a number of undesirable features of IED that lead us to believe that its broad application will hinder scientific progress.

One of the themes running through this issue of the Hastings Center Report is the complexity of how private moral commitments cash out in the public sphere. It's a theme I find both fascinating and important.The lead article is about how hospices in Oregon have dealt with the state's law permitting physician-assisted death. Most patients who have sought physician-assisted death in Oregon did so while in hospice, suggesting to some people that hospices are centrally involved in physician-assisted death—both in patients' (...) decision-making and in administering the medications. In fact, their involvement is much more limited and circumspect, as authors Courtney Campbell and Jessica Cox document.The focus of the article .. (shrink)

Human cloning raises the most profound questions about human nature, our faith in ourselves, and our ability to make decisions that could significantly alter the character of humanity. In this exciting and accessible book, Gregory Pence offers a candid and sometimes humorous look at the arguments for and against human cloning. Originating a human being by cloning, Pence boldly argues, should not strike fear in our hearts but should be examined as a reasonable reproductive option for couples. Pence considers (...) how popular culture has influenced the way we think about cloning, and he presents a lucid and non-technical examination of the scientific research and relevant moral issues in the cloning debate. This book is a must-read for anyone who is concerned about the impact of technology on human life and for those with interests in medical ethics, sociology, and public policy. (shrink)

This rich collection, popular among teachers and students alike, provides an in-depth look at major cases that have shaped the field of medical ethics. The book presents each famous (or infamous) case using extensive historical and contextual background, and then proceeds to illuminate it by careful discussion of pertinent philosophical theories and legal and ethical issues.

This collection highlights such issues as how the nature of time is relevant to the question of whether God is temporal and how God's other attributes are ...

A majority opinion seems to have emerged in scholarly analysis of the assortment of technologies that have been given the label “synthetic biology.” According to this view, society should allow the technology to proceed and even provide it some financial support, while monitor­ing its progress and attempting to ensure that the development leads to good outcomes. The near‐consensus is captured by the U.S. Presidential Commission for the Study of Bioethical Issues in its report New Directions: The Ethics of Synthetic Biology (...) and Emerging Technologies, which arguably marked the end of a preliminary round of analysis about the ethical and policy questions raised by synthetic bi­ology. Like a number of other, earlier documents issued by various groups around the world, the re­port called attention to questions about how the technology will be used; whether it might be mis­used; what sorts of accidents might happen along the way; the economic, environmental, and social impacts of the eventual applications; whether the very idea of “synthetic biology” should be trou­bling; and how the debate over all of these ques­tions will be conducted. Also like most similar documents, however, while it called for careful monitoring and oversight of technology, it did not recommend any significant new constraints on its development and use. The commission's stance was that it would be “imprudent either to declare a moratorium on synthetic biology until all risks can be determined and mitigated, or to simply ‘let science rip,’ regardless of the likely risks.”In this report, we will take stock of the current consensus, comment on some of the major points of disagreement, and identify the next steps for the debate. In part I, we offer a brief overview of the research and applications commonly grouped together under the heading of synthetic biology, partly in order to set the stage for the rest of the discussion and partly because we want to highlight some conceptual problems that attend the very la­bel given this field. In parts II, III, and IV, we take up, respectively, three broad classes of concerns that arise in the context of synthetic biology: con­cerns about the intrinsic or inherent value of do­ing synthetic biology, concerns about the concrete harms and benefits of doing synthetic biology, and concerns about justice. Addressing these concerns requires a method for bringing the public's values to bear on policy‐making concerning emerging biotechnologies; in part V, we discuss the chal­lenges in developing such a method.

A range of views on the morality of synthetic biology and its place in public policy and political discourse.

How strong is the argument for requiring public deliberation by very large publics—at national or even global levels—before moving forward with efforts to use gene editing on wild populations of plants or animals? Should there be a general moratorium on any such efforts until such broad public deliberation has been successfully carried out? This article works toward recommendations about the need for and general framing of broad public deliberation. It finds that broad public deliberation is highly desirable but not flatly (...) necessary before moving forward with any local cases of gene editing in the wild. It also finds that broad public deliberation would be most helpful in generating very general guidance and is unlikely to be appropriate for specific cases. Broad public deliberation is most helpful for cases that involve higher levels of uncertainty and moral ambiguity, but separating out a distinct class of cases for deliberation is not yet possible.

Much work in bioethics tries to sidestep bedrock questions about moral values. This is fine if we agree on our values; arguments about human enhancement suggest we do not. One bedrock question underlying these arguments concerns the role of emotion in morality: worries about enhancement are derided as emotional and thus irrational. In fact, both emotion and reason are integral to all moral judgment.

Financial ties between physicians and pharmaceutical companies are pervasive and controversial. However, little is known about how patients perceive such ties. This paper describes an experiment examining how a national sample of U.S. adults perceived a variety of financial relationships between physicians and drug companies. Each respondent read a single scenario about a hypothetical physician and his financial ties to the pharmaceutical industry; scenarios varied in terms of payment type of and amount. Respondents then evaluated the physician on several dimensions (...) . Findings revealed that perceptions of the physician were more strongly influenced by payment type than by payment amount. Specifically, respondents were quite critical of doctors who owned drug company stock or received industry payments for meals and lodging, but were more forgiving of physicians who received free drug samples or consulting fees . Interestingly, physicians who received no payments, while seen as honest, were also viewed by some respondents as inexperienced or uninformed about new treatments. Implications for public policy and future research are discussed. (shrink)

The emergence of de‐extinction is a study in technological optimism. What has already been accomplished in recovering ancient genomes, recreating them, and reproducing animals with engineered genomes is amazing but also has a long ways to go to achieve “de‐extinction” as most people would understand that term. Still, with some caveats in place, creating a functional replacement for an extinct species may sometimes be doable, and given the right goals, might sometimes make sense. The International Union for Conservation of Nature (...) guidelines for de‐extinction do a reasonable job of keeping the caveats in place and clarifying the goals. In fact, given the right caveats about what de‐extinction can accomplish, we should pay a lot of attention to the technology and should think carefully about the goals. Not only has the technology been advancing, but our environmental standards have been getting looser and more flexible, providing less guidance for implementing the technology. The guiding ideals for conservation are often explained as a choice between John Muir, founder of The Sierra Club, and Gifford Pinchot, who helped create the U.S. Forest Service. Muir argued for preserving some places in the world in their natural state because of their great value and beauty. Pinchot, by contrast, was bluntly utilitarian. He argued for trying to keep some natural places more or less undamaged so that we could use them later. There has long been dissatisfaction with this choice, and in the last couple of decades, a number of prominent voices have proposed a “gardening ethic” as a new standard that combines elements of Muir and Pinchot. A gardening ethic is supposed to both celebrate the land and declare that it must now be managed. But what would good gardening mean when it comes to de‐extinction? (shrink)

Financial relationships and business transactions between physicians and the health care industry are common. These relationships take a variety of forms, including payments to physicians in exchange for consulting services, reimbursement of physician travel expenses when attending medical device and pharmaceutical educational conferences, physician ownership in life science company stocks, and the provision of free drug samples. Such practices are not intrinsic to medical practice, but as the Institute of Medicine described in its 2009 report, these relationships have the potential (...) to produce positive collaborations that improve patient care and public health, and most physicians view it as “ethically proper to accept items ranging from drug samples to a lucrative consultantship.”However, financial relationships between physicians and pharmaceutical, medical device and biotechnology companies can also create negative influences on physician judgment that compromise patient care and jeopardize the public’s trust.

In How to Build a Better Human, prominent bioethicist Gregory E. Pence argues if, we are careful and ethical, we can use genetics, biotechnology, and medicine in safe ethical ways for human enhancement. He looks at the innovations and challenges that have occurred since the birth of bioethics almost 50 years ago and considers the ethical implications of the technological advances that are just around the corner.

God’s regular causal activity is traditionally held to include his creation of the world, his conserving all created things in being and his concurrence with the causal activities of finite causes. Divine causation requires that God is an agent. In this paper, I apply E. J. Lowe’s view of human agency to God. This application requires certain adjustments. Lowe takes it that when a person acts for reasons, these reasons are lacks of some kind. I argue that his account can (...) apply to God if we think of the reasons for God’s action as connected to purposes rather than to needs. (shrink)

: A comparison of casuistry with the strain of particularism developed by John McDowell and David Wiggins suggests that casuistry is susceptible to two very different mistakes. First, as sometimes developed, casuistry tends toward an implausible rigidity and systematization of moral knowledge. Particularism offers a corrective to this error. Second, however, casuistry tends sometimes to present moral knowledge as insufficiently systematized: It often appears to hold that moral deliberation is merely a kind of perception. Such a perceptual model of deliberation (...) cannot offer a convincing account of the possibility of moral progress. This second problem is one to which particularism is itself prone. To redress it, other aspects of casuistry must be exploited: Casuistry contains an account of presumptive generalizations that explains how moral deliberation might be structured by rules while also depending at critical junctures on perception.

Richard Dawkins’s best argument against the existence of God aims to show that the universe fits better with atheism than with theism. The fact that complex life developed gradually over a long period of time is required by an atheistic view but is not required by a theistic view. This fact, then, supports the atheistic view. This argument does raise the probability of atheism. I discuss four analogous arguments that point towards theism. I conclude that Dawkins’s argument lends some support (...) for atheism, but his strategy suggests sufficient arguments to see that the total case points in the opposite direction. (shrink)

In response to the need for Holocaust curricula in Latvia, Latvians and Americans worked collaboratively to overcome the historical silence surrounding this event. During their project, Latvian curriculum writers worked with teachers and scholars at the United States Holocaust Memorial Museum. This descriptive analysis of the Latvians' experience with Museum Fellows revealed opportunities to learn from each other the complexities of teaching the Holocaust in a country viewed by some as collaborators and still somewhat anti-Semitic. Findings included depth of guidance, (...) values, and limits of innovative teaching methods, cross-cultural benefits, and continued collaboration. Recommendations for future efforts by post-Communist countries and American partners to develop curriculum on teaching a most complex and contentious aspect of history such as the Holocaust conclude the study.

Can we make wise policy decisions about still‐emerging technologies—decisions that are grounded in facts yet anticipate unknowns and promote the public's preferences and values? There is a widespread feeling that we should try. There also seems to be widespread agreement that the central element in wise decisions is the assessment of benefits and costs, understood as a process that consists, at least in part, in measuring, tallying, and comparing how different outcomes would affect the public interest. But how benefits and (...) costs are best weighed when making decisions about whether to move forward with an emerging technology is not clear. Many commentators feel that the weighing is often inadequate or inappropriate. Those who argue for a “precautionary” approach to the weighing do so precisely because they feel the need for a restraint on the dominant decision‐making tools and processes for assessing outcomes.This Hastings Center special report examines those tools and processes, taking the method known as cost‐benefit analysis as a starting point. In U.S. governance, CBA, sometimes informed by risk assessment, is the most widely used and extensively studied method, and authoritative reports on genetic and reproductive technologies often use language suggestive of cost‐benefit analysis. There is also a long‐running debate about the role of values in CBA and other formal impact assessment mechanisms—and about how those mechanisms compare to the precautionary principle. The guiding idea in the report is to engage in a close examination of the strengths and limits of CBA for ensuring that emerging technologies are used in ways that square with the public's values, drawing on applications of synthetic biology to illustrate and sharpen the analysis and then considering corrections to CBA and some alternative methodologies that handle values differently.

This essay contends that God created humanity as His co-creators to bring Him glory with one’s entire being, including imagination and creativity. Throughout Scripture, YHWH is depicted as the artistic Creator of all that is beautiful, true, and transcendent. The Bible attests the creation of humanity in the imago Dei--sharing God’s innate creativity--and divine gifting of Spirit-inspired artisans utilizing their talents for God’s glory. Yet, over the centuries, “art” was oft misunderstood and grossly neglected in Christ’s church. Philip Ryken explains (...) how medieval skeptics began removing and destroying art believed to violate the Decalogue. Imbalanced suspicions toward art in Christendom still persist, despite the positive, inspirational effects of icons in Catholic and Orthodox traditions and scientific research that shows the therapeutic value of art across a broad spectrum of mental and physical challenges, including isolation and depression. Makoto Fujimura posits that Christian creatives possess a common faith as “border-walkers,” and can affect phoenix-like positive cultural and ecclesial change by reintroducing beauty as a visible “sermon” into a fragmented, post-pandemic world.

In this important new book Gregory E. Pence looks at issues on the frontiers of medicine including gene therapy to produce 'brave new babies,' cloning, human eggs and embryos for sale, and experiments on human embryos. Pence argues that the conservatism of the medical establishment, the bioethics community, and the public at large has created shibboleths that impede improvements in our quality of life.

In this article I reflect on meeting Professor Drucilla Cornell as a bachelor’s student at Rutgers University, working as her assistant, and the irreversible impact she had on my life. I argue that Cornell was a thinker of profound courage and that this virtue was crucial to her developing several ways beyond the philosophical anthropology of Euro-modern man. Cornell envisioned three main ways beyond what she called the “dead ends of man”: feminism, critical philosophy (including dialectics and Marxism), and African (...) humanism. These three traditions combine in an explosive, revolutionary way in Cornell’s writings; each are essential pillars of her thought. I also identify a dialectical or “productive” tension in her thinking between tendencies toward both idealist and materialist metaphysics. I conclude by recounting personal experiences with Cornell, exploring the consequences of her ethical philosophy, and posing questions that I think she could help us answer in the tumultuous times we are currently living through.

Concerns about the sacred—common in everyday moral thinking—have crept into bioethics in various forms. Further, given a certain view of the metaphysics of morals that is now widely endorsed in Western philosophy, there is in principle no reason that judgments about the sacred cannot be part of careful and reasoned moral deliberation.

Evan Fales has argued that divine causation is not possible. His central argument involves an analysis of causation that requires that there has to be a mapping feature to guarantee that the particular effect follows the particular cause. He suggests that being related in space and time will provide the means to map the right effects onto their causes. In this paper, I argue that the spatial relation between cause and effect is not necessary to the causal relation. In cases (...) of volition, it appears that the mapping of particular effects onto volitions is achieved by the intentional content of the volition. Therefore, spatial relations are not necessary to causation and the impossibility of divine causation has not been shown. (shrink)
