Modality specificity in priming is taken as evidence for independent perceptual systems. However, Easton, Greene, and Srinivas (1997) showed that visual and haptic cross-modal priming is comparable in magnitude to within-modal priming. Where appropriate, perceptual systems might share like information. To test this, we assessed priming and recognition for visual and auditory events, within- and across- modalities. On the visual test, auditory study resulted in no priming. On the auditory priming test, visual study resulted in priming that was only marginally (...) less than within-modal priming. The priming results show that visual study facilitates identification on both visual and auditory tests, but auditory study only facilitates performance on the auditory test. For both recognition tests, within-modal recognition exceeded cross-modal recognition. The results have two novel implications for the understanding of perceptual priming: First, we introduce visual and auditory priming for spatio-temporal events as a new priming paradigm chosen for its ecological validity and potential for information exchange. Second, we propose that the asymmetry of the cross-modal priming observed here may reflect the capacity of these perceptual modalities to provide cross-modal constraints on ambiguity. We argue that visual perception might inform and constrain auditory processing, while auditory perception corresponds to too many potential visual events to usefully inform and constrain visual perception.

Despite the effort on DSM-5 and ICD-11, few appear satisfied with these classification systems. We suggest that the core reason for dissatisfaction is expecting too much from them; they do not provide discrete categories that map to specific causes of disease, they describe clinical syndromes intended to guide treatment choices. Here we review work on anxiety and anxiety disorders to argue that while clinicians draw a pragmatic distinction between normal and abnormal emotions based on considerations such as severity and duration, (...) understanding the evolutionary origins and utility of the emotions, including the adaptive value of adverse emotions, is key for formulating comprehensive assessments of an individual patient’s symptoms and for providing a conceptual foundation for pharmacotherapy, psychotherapy, and public health.

Most philosophical explorations of responsibility discuss the topic solely in terms of metaphysics and the "free will" problem. By contrast, these essays by leading philosophers view responsibility from a variety of perspectives -- metaphysics, ethics, action theory, and the philosophy of law. After a broad, framing introduction by the volume's editors, the contributors consider such subjects as responsibility as it relates to the "free will" problem; the relation between responsibility and knowledge or ignorance; the relation between causal and moral responsibility; (...) the difference, if any, between responsibility for actions and responsibility for omissions; the metaphysical requirements for making sense of "collective" responsibility; and the relation between moral and legal responsibility. The contributors include such distinguished authors as Alfred R. Mele, John Martin Fischer, George Sher, and Frances Kamm, as well as important rising scholars. Taken together, the essays in _Action, Ethics, and Responsibility_ offer a breadth of perspectives that is unmatched by other treatments of the topic. Contributors: Joseph Keim Campbell, David Chan, Randolph Clarke, E.J. Coffman, John Martin Fischer, Helen Frowe, Todd Jones, Frances Kamm, Antti Kauppinen, Alfred R. Mele, Michael O'Rourke, Paul Russell, Robert F. Schopp, George Sher, Harry S. Silverstein, Saul Smilansky, Donald Smith, Charles T. Wolfe The hardcover edition does not include a dust jacket.

The phenomenon of ambivalence is an important one for any philosophy of action. Despite this importance, there is a lack of a fully satisfactory analysis of the phenomenon. Although many contemporary philosophers recognize the phenomenon, and address topics related to it, only Harry Frankfurt has given the phenomenon full treatment in the context of action theory – providing an analysis of how it relates to the structure and freedom of the will. In this paper, I develop objections to Frankfurt's account, (...) all revolving around the charge that his account contains a serious ambiguity between willing and identifying. With such objections in place, I then develop an analysis that avoids the difficulties and ambiguities that Frankfurt's analysis is prey to. I briefly distinguish ambivalence from other types of internal conflict. This paper aims to offer conceptual clarification on the phenomenon of ambivalence, which will then allow for discussions about the normative merits and demerits of ambivalence, the effects of ambivalence on autonomous action, and methods of resolution of ambivalence.

Two groups of scientists have just announced what is being described as a leap forward in human stem cell research.1–3 Both have found ways of producing what are being called “induced pluripotent cells” , stem cells that they hope will demonstrate the same key properties of regeneration and unrestricted differentiation that human embryonic stem cells possess, but which are derived from skin cells not from embryos. In simple terms, these scientists have succeeded in reprogramming skin cells to behave like hESCs.Stem (...) cell research has been hailed as one of the most important and exciting areas of science, because it is believed that these types of cells will not only play an important part in regenerative medicine, but also yield valuable scientific information. These latest developments in cell reprogramming represent a milestone for stem cell science. No longer does the paradigm of irreversible cell specialisation hold true; instead, almost any type of cell might have the potential to become any other.The advent of techniques for producing these iPCs has also been hailed as an ethical breakthrough. Up until now, the production of hESCs has required a process which involves the destruction of embryos. Many of these embryos are available as by-products of IVF; but in addition, the process of somatic cell nuclear transfer to produce cloned embryonic stem cells requires a supply of human oocytes, which must currently be harvested from female donors at no insignificant cost. In a nutshell, iPCs seem to enable us to produce “embryo-free” human pluripotent stem cells, and in a “gender-neutral” way—that is, without the need for human oocytes.The response from the scientific community, ethical commentators and the public has, however, reflected an inherent confusion over the ethical significance of this research.

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme-based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how (...) people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.

Bayesian probability has recently been proposed as a normative theory of argumentation. In this article, we provide a Bayesian formalisation of the ad Hitlerum argument, as a special case of the ad hominem argument. Across three experiments, we demonstrate that people's evaluation of the argument is sensitive to probabilistic factors deemed relevant on a Bayesian formalisation. Moreover, we provide the first parameter-free quantitative evidence in favour of the Bayesian approach to argumentation. Quantitative Bayesian prescriptions were derived from participants' stated subjective (...) probabilities (Experiments 1 and 2), as well as from frequency information explicitly provided in the experiment (Experiment 3). Participants' stated evaluations of the convincingness of the argument were well matched to these prescriptions. (shrink)

New UK consensus statement on core curriculum in medical ethics and lawThe most important paper in this month’s JME is not a standard paper but the new UK consensus statement on the core curriculum in medical ethics and law for medical students. The first consensus statement was published in the JME in 1998 and has been instrumental in ensuring the embedding of a common standard of teaching in these subjects across UK medical schools. 1 However, even the most hard core (...) moral realist has to accept that, even if the fundamental principles of ethics do not change, the best way to teach it might evolve and the problems of most interest may change as the healthcare system changes. The core curriculum can therefore not be cast in stone and must be revised and updated from time to time. The current revision is the result of an extensive process involving reviews of the way ….

Taking Ourselves Seriously and Getting It Right is written in a manner that is accessible to all. Frankfurt’s arguments are, as usual, clear and persuasive. Korsgaard’s, Bratman’s, and Dan-Cohen’s comments are thought provoking. There are, however, two main areas in which Frankfurt’s arguments need clarification (the notion of wholehearted identification, and the concept of ambivalence), and there are misunderstandings of Frankfurt at work in Korsgaard’s (relationship between the self and the will, and concept of the will for Frankfurt) and Bratman’s (...)

Background: While religious faith remains one of the most significant features of human life, little is known about its relationship to ordinary belief at the level of the brain. Nor is it known whether religious believers and nonbelievers differ in how they evaluate statements of fact. Our lab previously has used functional neuroimaging to study belief as a general mode of cognition, and others have looked specifically at religious belief. However, no research has compared these two states of mind directly. (...) Methodology/Principal Findings: We used functional magnetic resonance imaging to measure signal changes in the brains of thirty subjects - fifteen committed Christians and fifteen nonbelievers - as they evaluated the truth and falsity of religious and nonreligious propositions. For both groups, and in both categories of stimuli, belief was associated with greater signal in the ventromedial prefrontal cortex, an area important for self-representation, emotional associations, reward, and goal-driven behavior. This region showed greater signal whether subjects believed statements about God, the Virgin Birth, etc. or statements about ordinary facts. A comparison of both stimulus categories suggests that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks. Conclusions/Significance: While religious and nonreligious thinking differentially engage broad regions of the frontal, parietal, and medial temporal lobes, the difference between belief and disbelief appears to be content-independent. Our study compares religious thinking with ordinary cognition and, as such, constitutes a step toward developing a neuropsychology of religion. However, these findings may also further our understanding of how the brain accepts statements of all kinds to be valid descriptions of the world. © 2009 Harris et al. (shrink)

NICE must not say people are not worth treatingThe National Institute for Health and Clinical Excellence has proposed that drugs for the treatment of dementia be banned to National Health Service patients on the grounds that their cost is too high and “outside the range of cost effectiveness that might be considered appropriate for the NHS”i.1This is despite NICE’s admission that these drugs are effective in the treatment of Alzheimer’s disease and despite NICE having approved even more expensive treatments. The (...) effect is that thousands of Alzheimer’s patients will be denied the only treatment available. It is difficult to think of this as anything but wickedness or folly or more likely both. At the same time, and with no apparent sense of irony, NICE has launched a public consultation document3 on its guidelines on social value judgments. As we shall see these guidelines are ethically illiterate as well as socially divisive.Assuming permanently scarce resources it is clearly crucial that such healthcare resources as are available are not wasted. This point is often made in terms of cost effectiveness and it is argued, not implausibly, that to talk of cost effectiveness implies that we are able to measure just how cost effective each treatment is. To do so of course we need a standard of measurement. NICE has adopted the ubiquitous, but justly infamous QALY, the Quality Adjusted Life Year.The QALY combines life expectancy after treatment with measures of the expected quality of that life. There are two ways in which QALYS can be used. They might be used to determine which of rival therapies to give to a particular patient or which procedure to use to treat a particular condition, in short which of two different treatments is the more ….

The sporadic nature of Alzheimer's disease argues for an environmental link that may drive AD pathogenesis; however, the triggering factors and the period of their action are unknown. Recent studies in rodents have shown that exposure to lead during brain development predetermined the expression and regulation of the amyloid precursor protein and its amyloidogenic beta-amyloid product in old age. Here, we report that the expression of AD-related genes [APP, BACE1 ] as well as their transcriptional regulator were elevated in aged (...) monkeys exposed to Pb as infants. Furthermore, developmental exposure to Pb altered the levels, characteristics, and intracellular distribution of Abeta staining and amyloid plaques in the frontal association cortex. These latent effects were accompanied by a decrease in DNA methyltransferase activity and higher levels of oxidative damage to DNA, indicating that epigenetic imprinting in early life influenced the expression of AD-related genes and promoted DNA damage and pathogenesis. These data suggest that AD pathogenesis is influenced by early life exposures and argue for both an environmental trigger and a developmental origin of AD. (shrink)

It is commonly accepted that the golden rule—most often formulated as "do unto others as you would have them do unto you"—is a unifying element between many diverse religious traditions, both Eastern and Western. Its influence also extends beyond such traditions, since many non-religious individuals hold up the golden rule as central to their lives. Yet, while it is extraordinarily important and widespread, the golden rule is often dismissed by scholars as a vague proverb that quickly leads to absurdities when (...) one attempts to formulate it in clear terms. In this book, Harry J. Gensler defends the golden rule and addresses all of the major philosophic objections, pointing out several common misunderstanding and misapplications. Gensler first discusses golden-rule reasoning and how to avoid the main pitfalls. He then relates the golden rule to world religions and history, and to areas like moral education, egoism, evolution, society, racism, business, and medicine. The book ends with a discussion of theoretical issues . Ethics and the Golden Rule offers two introductory chapters, the first is simpler and the second more technical; a reader may start with either or both. One can then read any combination of further chapters, in any order, depending on one’s interests; but Chapters 13 and 14 are technical and assume one has read Chapter 2. This is "a golden-rule book for everyone," accessible to a wide readership. (shrink)

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predomi- nantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase ‘paradigm shift’ in (...) his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and col- leagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the man- agement of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples’ dogma makes his contribution truly a genuine paradigm shift.

There is a popular and widely accepted version of the precautionary principle which may be expressed thus: “If you are in a hole—stop digging!”. Tom Baldwin, as Deputy Chair of the Human Fertilisation and Embryology Authority , may be excused for rushing to the defence of the indefensible,1 the HFEA’s sex selection report,2 but not surely for recklessly abandoning so prudent a principle. Baldwin has many complaints about my misrepresenting the HFEA and about my supposed elitist contempt for public opinion; (...) readers of this exchange will decide for themselves.REDRAFTING THE REPORTBaldwin begins with a piece of wishful thinking:"Harris objects that in this recommendation “an absurdly high standard of caution is employed”, since a theoretical risk is associated with almost all medical procedures. This objection is misplaced: as paragraph 142 of the report indicates, the phrase “theoretical risk” is to be understood here in the light of the earlier discussion of the risks arising from the fact that flow cytometry exposes sperm to laser energy, a procedure which is known to be liable to damage DNA."Paragraph 142 does not make that clear. It does indeed refer back to a set of earlier paragraphs but these give, if anything, an upbeat assessment of the safety of flow cytometry. Paragraph 121 states: “However whilst potentially less intrusive, and with potentially lower risk to the health of patients, flow cytometry …” .2 But even if the overall burden of the report does indicate unresolved fears, the standard is still absurdly high. However, so far from endorsing the report’s judgement that flow cytometry has “potentially lower risk to the health of patients”, Baldwin now regards the risk of flow cytometry as “serious”1:"Since the application of flow cytometry to humans is a new procedure, the risk of … ".

There are two well‐known ways of doing arithmetic with ordinal numbers: the “ordinary” addition, multiplication, and exponentiation, which are defined by transfinite iteration; and the “natural” (or “Hessenberg”) addition and multiplication (denoted ⊕ and ⊗), each satisfying its own set of algebraic laws. In 1909, Jacobsthal considered a third, intermediate way of multiplying ordinals (denoted × ), defined by transfinite iteration of natural addition, as well as the notion of exponentiation defined by transfinite iteration of his multiplication, which we denote. (...) (Jacobsthal's multiplication was later rediscovered by Conway.) Jacobsthal showed these operations too obeyed algebraic laws. In this paper, we pick up where Jacobsthal left off by considering the notion of exponentiation obtained by transfinitely iterating natural multiplication instead; we shall denote this. We show that and that ; note the use of Jacobsthal's multiplication in the latter. We also demonstrate the impossibility of defining a “natural exponentiation” satisfying reasonable algebraic laws.

Many people question whether God is the source of morality. Under divine command theory, God's will creates the moral order, and therefore ethical truths are true because of God's will. Under natural law, on the other hand, some ethical truths do not depend on God's will, and yet perhaps they depend on his reason or creation. Ethics and Religion develops strong, defensible, and original versions of both divine command theory and natural law. The book also discusses ethics and atheism: how (...) atheists object on ethical grounds to belief in God and how they view ethics. The book defends belief in God from criticisms and analyzes related concepts, such as practical reason, the golden rule, ethics and evolution, the problem of evil, and the fine-tuning argument.

This paper argues that the HFEA’s recent report on sex selection abdicates its responsibility to give its own authentic advice on the matters within its remit, that it accepts arguments and conclusions that are implausible on the face of it and where they depend on empirical claims, produces no empirical evidence whatsoever, but relies on reckless speculation as to what the “facts” are likely to be. Finally, having committed itself to what I call the “democratic presumption”, that human freedom will (...) not be constrained unless very good and powerful reasons can be produced to justify such infringement of liberty, the HFEA simply reformulates the democratic presumption as saying the opposite—namely that freedom may only be exercised if powerful justifications are produced for any exercise of liberty.

ABSTRACT:This article examines the issue of gender equality within Islam in order to develop an ethical framework for businesses operating in Muslim majority countries. We pay attention to the role of women and seemingly inconsistent expectations of Islamic and Western societies with regard to appropriate gender roles. In particular, we contrast a mainstream Western liberal individualist view of freedom and equality—the capability approach, used here as an illustration of mainstream Western liberalism—with an egalitarian Islamic view on gender equality. While the (...) article identifies an opportunity for this particular approach to reform patriarchal interpretations and practices of Islam toward gender egalitarian interpretations and practices, it also contests the notions of adaptation and well-being inherent within the capability approach. We suggest that a dialectical approach to understanding the relationships among religion, culture, and business provides a better guide to responsible business action in Muslim Majority countries than does the capability approach.
