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)
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)
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.
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 ...
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.
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.
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.
As the #1 topic in bioethics, cloning has made big news since Dolly's announced birth in 1998. In a new book building on his classic Who's Afraid of Human Cloning?, pioneering bioethicist Gregory E. Pence continues to advocate a reasoned view of cloning. Beginning with his surreal experiences as an expert witness before Congressional and California legislative committees, Pence analyzes the astounding recent progress in animal cloning; the coming surprises about human cloning; the links between animal, stem cell, and (...) human cloning; embryo politics; and other hot topics like artificial wombs and transgenic animals. -/- Pence rebuts the growing chorus of naysayers headed by Leon Kass, chairman of the President's Council on Bioethics, who attack the biomedical sciences, and explains why cloning will save endangered species and beloved pets, and help future children and people with degenerative diseases.

In The Ethics of Food, Gregory E. Pence brings together a collection of voices who share the view that the ethics of genetically modified food is among the most pressing societal questions of our time. This comprehensive collection addresses a broad range of subjects, including the meaning of food, moral analyses of vegetarianism and starvation, the safety and environmental risks of genetically modified food, issues of global food politics and the food industry, and the relationships among food, evolution, and (...) human history.

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)
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)
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.

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.

: 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.

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.

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)
In a recent issue of this journal, Kevin Corcoran has argued that the metaphysical theory one holds to about the nature of human persons is irrelevant to the sort of ethical questions that occupy bioethicists as well as the general public. Specifically, he argues that whether one holds a constitution view of human persons, an animalist view, or a substance dualist view, the real work in one’s ethical reasoning is done by certain moral principles rather than by metaphysical ones. I (...) raise objections to his analysis and propose that it is a combination of ethical principles and metaphysical principles that does the work in our judgements about the morality of abortion and other actions.
