SummaryThe Gainj of highland Papua New Guinea do not use contraception but have a total fertility rate of only 4·3 live births per woman, one of the lowest ever recorded in a natural fertility setting. From an analysis of cross-sectional demographic and endocrinological data, the causes of low reproductive output have been identified in women of this population as: late menarche and marriage, a long interval between marriage and first birth, a high probability of widowhood at later reproductive ages, low (...) effective fecundability and prolonged lactational amenorrhoea. These are combined with near-universal marriage, a low prevalence of primary sterility and a pattern of onset of secondary sterility similar to that found in other populations. Of all the factors limiting fertility, by far the most important are those involved in birth spacing, especially lactational amenorrhoea. (shrink)

Classical Christology provides reason to reject the principle of alternative possibilities [PAP]. The Gethsemane prayer highlights an instance in which Jesus Christ performs a voluntary and morally significant action which he could not have done otherwise, namely, Christ’s submission to God’s will. Two classical Christological doctrines undermine PAP: impeccability, and volitional non-contrariety. Classical Christology teaches that Christ could not sin, and that Christ’s human will could not be contrary to his divine will. Yet, classical Christology also teaches that Christ’s death (...) is voluntary and morally praiseworthy. First, I present the relevant elements of classical Christology: dyothelitism, impeccability, and volitional non-contrariety. Second, I define and disambiguate varieties of PAP. Third, I show that Christ’s prayer in Gethsemane disproves PAP. I respond to several objections along the way. Finally, I reflect on the implications of denying PAP. (shrink)

This book examines the lived experiences and work of African American women educators during the 1880s to the 1960s.

In a fictional conversation designed to appeal to both working teachers and social philosophers, three educators take up the question of whether critical thinking itself can, or should, be taught independently of an explicit consideration of issues related to social justice. One, a thoughtful but somewhat traditional Enlightenment rationalist, sees critical thinking as a neutral set of skills and dispositions, essentially unrelated to the conclusions of morality, problems of social organization, or the content of any particular academic discipline. A second (...) interlocutor, steeped in “critical” pedagogy of Paulo Freire, insists that the problem is the pose of neutrality itself. On this view, all honest and effective approaches to teaching must confront the hegemony of unjust relationships, institutions, and conceptual schemes. The third character attempts to resolve the tension between these two opposed camps. (shrink)

This dialogue discusses a proposal for the legalization of torture under specific circumstances and contrasts it with arguments for a total ban on torture. We consider three types of objection: first, that the difficulty of having adequate knowledge renders the stock “ticking bomb” scenario such a low-probability hypothetical as to present no realistic threat to a policy banning all torture; second, that empirically the information gleaned from torture is so unlikely to be reliable that it could not justify the moral (...) risk; and third, that sanctioning torture, even if only under the most extreme circumstances, would generate a ‘culture of torture,’ hence undermining fragile advances in international human rights rooted in unwavering commitment to human dignity. Compelling as these arguments appear, not all the conversants are wholly convinced by them; to this extent the dialogue ends aporetically. (shrink)

The discovery of a novel polypeptide (Islet Amyloid Polypeptide: IAPP) isolated from human and cat islet amyloid and from amyloid of a human insulinoma is reviewed. Structurally, IAPP from the human and cat resembles calcitonin gene‐related peptide (CGRP). The structural similarities between the neuropeptide CGRP and IAPP support the premise that IAPP is hormonal in nature. Our immunohistochemical studies also indicate that normal islet B‐cells of several mammalian species (including man and cat) give strong immunoreactivity with antiserum directed to a (...) synthetic peptide segment of IAPP. The fact that IAPP is deposited as amyloid in the pancreatic islets of type 2 (noninsulin‐dependent) diabetics strongly supports an important but yet unknown link between IAPP and the development of this disease.

SummaryThe effects of infant suckling patterns on the post-partum resumption of ovulation and on birth-spacing are investigated among the Gainj of highland New Guinea. Based on hormonal evidence, the median duration of lactational anovulation is 20·4 months, accounting for about 75% of the median interval between live birth and next successful conception. Throughout lactation, suckling episodes are short and frequent, the interval changing slowly over time, from 24 minutes in newborns to 80 minutes in 3-year olds. Maternal serum prolactin concentrations (...) decline in parallel with the changes in suckling patterns, approaching the level observed in non-nursing women by about 24 months post-partum. A path analysis indicates that the interval between suckling episodes is the principal determinant of maternal prolactin concentration, with time since parturition affecting prolactin secretion only in so far as it affects suckling frequency. The extremely prolonged contraceptive effect of breast-feeding in this population thus appears to be due to a slow decline in suckling frequency with time since parturition and absence of a decline over time in hypothalamic–pituitary responsiveness to the suckling stimulus.

In this informed and comprehensive assessment of current issues in international policies, Kenneth W. Thompson addresses the role that traditions and values play in shaping change and in helping us to understand its implications. He challenges the idea that the enormous changes in contemporary national and international life have rendered the consideration of traditions and values obsolete. Thompson’s purpose is to illuminate the problems we face and to set forth general principles directed toward an informing theory on traditions and (...) values as they affect politics and diplomacy, while at the same time warning of the pitfalls and limitations of theory. In the first section of this book, Thompson draws on classical and Judaeo-Christian traditions in defining the relationship between philosophy, religion, and politics. He then examines the application of abstract values to such political realities as national interest, and goes on to consider the question of moral values in international diplomacy and politics. In a series of case studies, Thompson reflects on human rights, disarmament and arms control, and human survival. Maintaining that the implementation of traditions and values is sometimes uniquely the task of the American presidency, he studies the administrations of four postwar presidents—Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, and Richard M. Nixon—in the light of the executives’ attitudes toward ethics and politics. Finally, Thompson considers the implications of national decline and the breakdown of international order for the future of the United States. The vast knowledge of international affairs and the literature of politics that Kenneth W. Thompson brings to this timely and reflective books makes it exceptionally readable as well as intellectually challenging. (shrink)

Our thesis is that reasoning plays a greater—or at least a different—role in understanding oral discourse such as lectures and speeches than it does in understanding comparatively long written discourse. For example, both reading and listening involve framing hypotheses about the direction the discourse is headed. But since a reader can skip around to check and revise hypotheses, the reader’s stake in initially getting it right is not as great as the listener’s, who runs the risk of getting hopelessly lost. (...) We also consider how representing the content of discourse and dealing with its pragmatic logic differs in reading and listening. (shrink)

“Imagination may be thought of as a ‘work-around.’ It is a resourceful tactic to ‘undo’ a rule by creating a path around it without necessarily defying it.... Transgression, on the other hand, is rule breaking. There is no pretense of reinterpretation; it is defiance pure and simple. Whether imagination or disobedience is the source, constraints need not constrain, ties need not bind.” So writes Kenneth A. Shepsle in his introduction to Rule Breaking and Political Imagination. Institutions are thought to (...) channel the choices of individual actors. But what about when they do not? Throughout history, leaders and politicians have used imagination and transgression to break with constraints upon their agency. Shepsle ranges from ancient Rome to the United States Senate, and from Lyndon B. Johnson to the British House of Commons. He also explores rule breaking in less formal contexts, such as vigilantism in the Old West and the CIA’s actions in the wake of 9/11. Entertaining and thought-provoking, Rule Breaking and Political Imagination will prompt a reassessment of the nature of institutions and remind us of the critical role of political mavericks.

Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, (...) that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory led to transitive causal judgments. On the other hand, chains schematized as multiple chunks led to intransitive judgments despite strong intermediate links. Normative accounts of causal intransitivity could not explain these intransitive judgments. (shrink)

My aesthetic judgements seem to make claims on you. While some popular accounts of aesthetic normativity say that the force of these claims is third-personal, I argue that it is actually second-personal. This point may sound like a bland technicality, but it points to a novel idea about what aesthetic judgements ultimately are and what they do. It suggests, in particular, that aesthetic judgements are motions in the collective legislation of the nature of aesthetic activity. This conception is recommended by (...) its ability to explain some important but otherwise recondite features of aesthetic practice and, more importantly, by allowing us to ground the normativity of aesthetic judgement in the familiar normativity of practice. It also offers a more systematic way of understanding the rivalry between the ideals of aesthetic universality and diversity. (shrink)

You might think a simple “No” would suffice as an answer. But there are features of Kant’s ethics that appear to be strikingly similar to virtue oriented views, so striking that some Kantians themselves have argued that Kant’s ethics in fact shares these features with virtue ethics. In what follows, I will argue against this view, though along the way I will acknowledge the features of Kant’s view that make it appear more like a kind of virtue ethics than it (...) really is. My plan is to first set out the distinctive features of what is nowadays called “virtue ethics”, those features that make it a genuine alternative to other normative theories. I then consider the features Kant’s view might share in common with virtue ethics and the case for saying that it is, therefore, fundamentally the same sort of theory. I follow these two sections with an argument against this position. I want to warn you at the outset, however, that my argument itself will be quite unsurprising, since it is an argument that has been central to the way in which most philosophers have understood Kant’s ethics. Any novelty I can claim here is in my account of what makes virtue ethics a genuine alternative to other normative theories, and my defense of this argument against those, in particular Barbara Herman, who have apparently found the argument unpersuasive.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors (...) We Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

This chapter develops and defends an account of reason: to reason is to scrutinize one’s attitudes by consulting the perspectives of other persons. The principal attraction of this account is its ability to vindicate the unique of authority of reason. The chapter argues that this conception entails that reasoning is a robustly social endeavor—that it is, in the first instance, something we do with other people. It is further argued that such social endeavors presuppose mutual respect on the part of (...) those participating in them. The account therefore yields a form of Kantian constructivism: we have an unconditional duty of respect for persons because such a duty is implicit in the very nature of reasoning. -/- . (shrink)

Many people find comparisons of the value of persons distasteful, even immoral. But what can be said in support of the claim that persons have incomparable worth? This chapter considers an argument purporting to show that the value of persons is incomparable because it is so great—because it is infinite. The argument rests on two claims: that the value of our capacity for valuing must equal or exceed the value of things valued and that our capacity for valuing is unbounded (...) in a very strong sense. After laying out this argument, I consider its implications for how we should regard each other. In particular, I suggest that it complicates efforts to understand morality as a system of principles. Instead, I propose that an aesthetic attitude, not unlike our experience of the sublime, is an apt response to humanity’s infinite value. -/- . (shrink)

Two problems are considered here. One relates to who has moral status, and the other relates to who has moral responsibility. The criteria for mattering morally have long been disputed, and many humans and nonhuman animals have been considered “marginal cases,” on the contested edges of moral considerability and concern. The marginalization of humans and other species is frequently the pretext for denying their rights, including the rights to health care, to reproductive freedom, and to bodily autonomy. There is broad (...) agreement across cultural and philosophical traditions about the capacities and responsibilities of moral agents. I propose an inclusive and expansive way of thinking about moral status, situating it not in the characteristics or capacities of individuals, but in the responsibilities and obligations of moral agents. Moral agents, under this view, are not privileged or entitled to special treatment but rather have responsibilities. I approach this by considering some African communitarian conceptions of moral status and moral agency. I propose that moral agency can also be more expansive and include not just individual moral agents but collective entities that have some of the traits of moral agents: power, freedom, and the capacity to recognize and act on the demands of morality and acknowledge and respect the rights of others. Expanding who and what is a moral agent correspondingly extends moral responsibility for respecting rights and fostering the conditions for the health and well-being of humans and animals onto the collective entities who uniquely have the capacity to attend to global-scale health threats such as pandemics and human-caused climate change.
