During meiosis, homologous chromosomes must pair in order to permit recombination and correct chromosome segregation to occur. Two recent papers1,2 show that meiotic pairing is also important for correct gene expression during meiosis. They describe data for the filamentous fungus Neurospora crassa that show that a lack of pairing generated by ectopic integration of genes can result in silencing of genes expressed during meiosis. This can result in aberrant meioses whose defects are specific to the function of the unpaired gene. (...) Furthermore, mutations affecting the silencing mechanism have been selected in a gene encoding a putative RNA‐dependent RNA polymerase. This finding indicates the involvement of a meiotic specific post‐transcriptional gene silencing mechanism (PTGS) similar to that observed in vegetative cells in N. crassa and other organisms. Finally, this gene product is essential for normal meiosis, suggesting that RNA‐dependent processes are fundamental to the sexual cycle. BioEssays 25:99–103, 2003. © 2003 Wiley Periodicals, Inc.

Using data collected from people with at least one brother and one sister, and consistent with an evolutionary perspective, we find that older men and women (a) are more upset by a brother’s partner’s sexual infidelity than by her emotional infidelity and (b) are more upset by a sister’s partner’s emotional infidelity than by his sexual infidelity. There were no effects of participant sex or sex of in-law on upset over a sibling’s partner’s infidelities, but there was an effect of (...) participant sex on reports of upset over one’s own partner’s infidelities. The results suggest that the key variable among older participants is the sex of the sibling or, correspondingly, the sex of the sibling’s partner, as predicted from an evolutionary analysis of reproductive costs, and not the sex of the participant, as predicted from a socialization perspective. Discussion offers directions for future work on jealousy. (shrink)

Young men are more distressed by a partner’s sexual infidelity, whereas young women are more distressed by a partner’s emotional infidelity. The present research investigated (a) whether the sex difference in jealousy replicates in an older sample, and (b) whether younger people differ from older people in their selection of the more distressing infidelity scenario. We presented forced-choice dilemmas to 202 older people (mean age = 67 years) and to 234 younger people (mean age = 20 years). The sex difference (...) replicated in the older sample. In addition, older women were less likely than younger women to select a partner’s emotional infidelity as more distressing than a partner’s sexual infidelity. Discussion offers directions for future work on sex differences and age differences in jealousy. (shrink)

Michael Bergmann seeks to motivate his externalist, proper function theory of epistemic justification by providing three objections to the mentalism and mentalist evidentialism characteristic of nonexternalists such as Richard Feldman and Earl Conee. Bergmann argues that (i) mentalism is committed to the false thesis that justification depends on mental states; (ii) mentalism is committed to the false thesis that the epistemic fittingness of an epistemic input to a belief-forming process must be due to an essential feature of that input, (...) and, relatedly, that mentalist evidentialism is committed to the false thesis that the epistemic fittingness of doxastic response B to evidence E is an essential property of B–E; and (iii) mentalist evidentialism is “unmotivated”. I object to each argument. The argument for (i) begs the question. The argument for (ii) suffers from the fact that mentalist evidentialists are not committed to the consequences claimed for them; nevertheless, I show that there is, in the neighborhood, a substantive dispute concerning the nature of doxastic epistemic fittingness. That dispute involves what I call “Necessary Fittingness”, the view that, necessarily, exactly one (at most) doxastic attitude ( belief , or disbelief , or suspension of judgment ) toward a proposition is epistemically fitting with respect to a person’s total evidence at any time. Reflection on my super-blooper epistemic design counterexamples to Bergmann’s proper function theory reveals both the plausibility of Necessary Fittingness and a good reason to deny (iii). Mentalist evidentialism is thus vindicated against the objections. (shrink)

What system of morals should rational people select as the best for society? Using a contemporary psychological theory of action and of motivation, Richard Brandt's Oxford lectures argue that the purpose of living should be to strive for the greatest good for the largest number of people. Brandt's discussions range from the concept of welfare to conflict between utilitarian moral codes and the dictates of self-interest.

Scholars of ethics, and of human behavior more generally, will find this book consistently stimulating and rewarding.

Richard Brandt is one of the most eminent and influential of contemporary moral philosophers. His work has been concerned with how to justify what is good or right not by reliance on intuitions or theories about what moral words mean but by the explanation of moral psychology and the description of what it is to value something, or to think it immoral. His approach thus stands in marked contrast to the influential theories of John Rawls. The essays reprinted in (...) this collection span a period of almost 30 years and include many classic pieces in metaethical and normative ethical theory. The collection is aimed at both those moral philosophers familiar with Brandt's work and at those philosophers who may be largely unfamiliar with his work. The latter group will be struck by the lucid unpretentious style and the cumulative weight of Brandt's contributions to topics that remain at the forefront of moral philosophy. (shrink)

This essay demonstrates proof-theoretically the consistency of a type-free theoryC with an unrestricted principle of comprehension and based on a predicate logic in which contraction (A (A B)) (A B), although it cannot holds in general, is provable for a wide range ofA's.C is presented as an axiomatic theoryCH (with a natural-deduction equivalentCS) as a finitary system, without formulas of infinite length. ThenCH is proved simply consistent by passing to a Gentzen-style natural-deduction systemCG that allows countably infinite conjunctions and in (...) which all theorems ofCH are provable.CG is seen to be a consistent by a normalization argument. It also shown that in a senseC is highly non-extensional. (shrink)

The relief of suffering is the great goal of medicine. That physicians give up on suffering when they can do nothing about the underlying condition is one of the contemporary criticisms of medicine. Yet even in irremediable suffering there is something noble, to which physicians should attend.

Richard Brandt is one of the most influential moral philosophers of the second half of the twentieth century. He is especially important in the field of ethics for his lucid and systematic exposition of utilitarianism. This new book represents in some ways a summation of his views and includes many useful applications of his theory. The focus of the book is how value judgments and moral belief can be justified. More generally, the book assesses different moral systems and theories (...) of justice, and considers specific problems such as the optimal level of charity and the moral tenability of the criminal law. This book will be essential reading for all professional philosophers concerned with ethics, and will prove helpful to students as well. (shrink)

This essay critically explores resources and reasons for the study of culture in religious ethics, paying special attention to rhetorics and genres that provide an ethics of ordinary life. I begin by exploring a work in cultural anthropology that poses important questions for comparative and cultural inquiry in an age alert to "otherness," asymmetries of power, the end of value-neutrality in the humanities, and the formation of identity. I deepen my argument by making a foundational case for the importance of (...) culture as a topic of normative analysis through a discussion of the emotions as cultural artifacts. To illustrate how cultural analysis can inform religious ethics, I turn to works by Wayne Meeks, Margaret Trawick, and Charles Taylor. I conclude by sketching some implications of a "cultural turn" for future work in religious ethics. (shrink)

This book presents a theoretical treatment of externalities, public goods, and club goods. The new edition updates and expands the discussion of externalities and their implications, coverage of asymmetric information, underlying game-theoretic formulations, and intuitive and graphical presentations. Aimed at well-prepared undergraduates and graduate students making a serious foray into this branch of economics, the analysis should also interest professional economists wishing to survey recent advances in the field. No other single source for the range of materials explored is currently (...) available. Topics investigated include Nash equilibrium, Lindahl equilibria, club theory, preference-revelation mechanism, Pigouvian taxes, the commons, Coase Theorem, and static and repeated games. The authors use mathematical techniques only as much as necessary to pursue the economic argument. They develop key principles of public economics that are useful for subfields such as public choice, labor economics, economic growth, international economics, environmental and natural resource economics, and industrial organization.

Interventions are medically necessary when they are vital in achieving the goal of medicine. However, with varying perspectives comes varying views on what interventions are (un)necessary and, thus, what potential treatment options are available for those suffering from the myriad of conditions, pathologies and disorders afflicting humanity. Medical necessity's teleological nature is perhaps best illustrated in cases where there is debate over using contentious medical interventions as a last resort. For example, whether it is appropriate for those suffering from body (...) integrity dysphoria to receive healthy limb amputations. This paper explores how one's perception of medicine's goal underpins whether interventions are necessary or unnecessary, using the controversial topic of therapeutic amputation as an example. By contrasting ‘classical’ amputations with their more contentious counterparts, it highlights how the idea of medical necessity influences and restrains clinical decision-making. The paper starts by giving an account of body integrity dysphoria, focusing on the debate concerning elective amputation's justifiability. It then introduces Georges Canguilhem's vitalist theory of health, paying particular attention to his emphasis on adaptability. Then, this paper uses his theory as a lens through which to evaluate the appropriateness of therapeutic amputation as a medically necessary procedure. Ultimately, the paper highlights how the label of medical necessity is withheld from potential therapeutic interventions because they fail to conform to pre-established ideas of medicine's purpose and that by doing so, potential harm befalls those who are left with no effective treatments and must look for solutions in the non-clinical world.

Analytically inclined philosphers of religion have commonly assumed that 1) “God” must be defined before arguments for or against his existence can be evaluated 2) the history of religious beliefs is irrelevant to their justification. In this paper I apply the causal theory of reference to “God” and challenge both assumptions. If, as Freud supposes, “God” originates in the delusions of the mentally ill then it does not refer. On the other hand, if “God” originates in encounters with some Entity, (...) no matter how vaguely conceived, then That is God. (shrink)

Individuals with body integrity identity disorder seek to address a non-delusional incongruity between their body image and their physical embodiment, sometimes via the surgical amputation of healthy body parts. Opponents to the provision of therapeutic healthy-limb amputation in cases of BIID make appeals to the envisioned harms that such an intervention would cause, harms such as the creation of a lifelong physical disability where none existed before. However, this concept of harm is often based on a normative biomedical model of (...) health and disability, a model which conflates amputation with impairment, and impairment with a disability. This article challenges the prima facie harms assumed to be inherent in limb amputation and argues in favour of a potential treatment option for those with BIID. To do this, it employs the social model of disability as a means to separate the concept of impairment and disability and thereby separate the acute and chronic harms of the practice of therapeutic healthy-limb amputation. It will then argue that provided sufficient measures are put in place to ensure that those with atypical bodily constructions are not disadvantaged, the chronic harms of elective amputation would cease to be.

Opponents of the provision of therapeutic, healthy limb amputation in Body Integrity Identity Disorder cases argue that such surgeries stand in contrast to the goal of medical practice – that of health restoration and maintenance. This paper refutes such a conclusion via an appeal to the nuanced and reflective model of health proposed by Georges Canguilhem. The paper examines the conceptual entanglement of the statistically common with the normatively desirable, arguing that a healthy body can take multiple forms, including that (...) of an amputee, provided that such a form enables the continuing ability to initiate new norms of existence. It concludes that the practice of healthy limb amputation in cases of Body Integrity Identity Disorder is not only compatible with the goal of medicine but is potentially the only method of achieving this goal in the face of a complex and often mischaracterized disorder.
