In Book 9 of Plato's Republic we find three proofs for the claim that the just person is happier than the unjust person. Curiously, Socrates does not seem to consider these arguments to be coequal when he announces the third and final proof as ‘the greatest and most decisive of the overthrows’. This remark raises a couple of related questions for the interpreter. Whatever precise sense we give to μέγιστον and κυριώτατον in this passage, Socrates is clearly appealing to an (...) argumentative standard of some kind, and claiming that his final argument alone meets this standard. But what precise standard is Socrates invoking here? And given that the first two arguments of Book 9 fall short of this standard, why does he not simply leap directly to the third, most decisive proof? (shrink)

This paper addresses two interpretive puzzles in Plato’s Philebus. The first concerns the claim, endorsed by both interlocutors, that the most godlike of lives is a pleasureless life of pure thinking. This appears to run afoul of the verdict of the earlier so-called ‘Choice of Lives’ argument that a mixed life is superior to either of its ‘pure’ rivals. A second concerns Socrates’ discussion of false pleasure, in which he appears to be guilty of rank equivocation. I argue that we (...) can solve both puzzles by attributing to Plato an account of pleasure as a species of intentional attitude. (shrink)

The Protagoras is a contest of philosophical methods. With its mix of μῦθος and λόγος, Protagoras’ Great Speech stands as a competing model of philosophical discourse to the Socratic elenchus. While the mythical portion of the speech clearly impresses its audience—Socrates included—one of its central claims appears to pass undefended. This is the claim that the political art cannot be distributed within a community as the technical arts are. This apparent shortcoming of the Great Speech does not seem to trouble (...) philosophical commentators: it is a myth, after all, and it seems reasonable to suppose that the sly sophist slips certain claims into his myth precisely to avoid having to defend them. Nevertheless, it is worth subjecting the claim to philosophical scrutiny. What could be the reason that the political art had to be distributed differently than were the technical arts, as the myth insists? (shrink)

The eclectic problem solving methodology used by the British Medical Association is described in this paper. It has grown from the daily need to respond to doctors’ practical queries and incorporates reference to law, traditional professional codes, and established BMA policies—all of which must be regularly assessed against the benchmark of contemporary societal expectations. The two Jehovah’s Witness scenarios are analysed, using this methodology and in both cases the four principles solution is found to concur with that of the BMA’s (...) approach. The author’s overall conclusion is that although the BMA resorts to a lengthier list of thins to consider, the solutions that emerge are often likely to coincide with the four principles approach.

Many normative political theorists have engaged in the systematic collection and/or analysis of empirical data to inform the development of their arguments over the past several decades. Yet, the approach they employ has typically not been treated as a distinctive mode of theorizing. It has been mostly overlooked in surveys of normative political theory methods and methodologies, as well as by those critics who assert that political theory is too abstracted from actual political contestation. Our aim is to unearth this (...) grounded normative theory (GNT) approach – to identify its definitive practices and highlight its potential significance. We detail four overlapping commitments characteristic of GNT. These include commitments to expanding the comprehensiveness of input for normative arguments through original empirical research and/or analysis, recursivity in the development of normative claims, attentiveness to the systematic inclusion of a range of voices and ways of knowing, and accountability to those engaged by the theorist in empirical contexts. We discuss methodological distinctions within GNT, including between more- and less-solidaristic approaches. We discuss how GNT answers calls for theorists to engage more closely with empirical political dynamics and we consider responses to possible critiques. (shrink)

Can we respond to injustices in the world in ways that do more than just address their consequences? In this book, Brooke A. Ackerly argues that what to do about injustice is not just an ethical or moral question, but a political question about assuming responsibility for injustice. Ultimately, Just Responsibility offers a theory of global injustice and political responsibility that can guide action.

In the Law of Civilisation and Decay, Adams considers various societies and civilisations by the symbolism, manner and influence of their coinage, and concludes that a society or civilisation becomes sapped of its culture-vigour, when entering a cycle where money becomes the dominant factor rather than merely serving as a mechanism.

This is Thomas Reid's greatest work. It covers far more philosophical ground than the earlier, more popular Inquiry. The Intellectual Powers and its companion volume, Essays on the Active Powers of Man, constitute the fullest, most original presentation of the philosophy of Common Sense. In the process, Reid provides acutely critical discussions of an impressive array of thinkers but especially of David Hume. In Reid's eyes, Hume had driven a deep tendency in modern philosophy to its ultimate conclusions by creating (...) a phantom-world of so-called 'ideas' that sprang from objects of observation; the self was a conglomeration of perceived ideas; and the will as the source of action was nothing but the balance of passionate impulses. -/- Reid's Common Sense philosophy answers these problems by suggesting that sceptics, such as Hume, unavoidably affirm what they purport to deny, namely the existence of a stable external world, of other minds, of the continuity of their own minds, and of their own and other people's ability to ascribe and accept responsibility for actions. We can understand all of this by proper empirical observation and philosophical analysis of the activity of the mind. Reid's major positive contribution to philosophy is a detailed account of the various innate powers of the mind. While particularly influential in the first half of the nineteenth century, Reid's work has retained a significant role in philosophy, not least in recent years. At the same time, his role in the Scottish Enlightenment is becoming much better understood. -/- This is the only properly established text. It is accompanied by manuscript lectures on the nature and immortality of the soul, as well as helpful editorial annotation and introduction, making it useful to a wide variety of readers. -/- Key Features: -/- Accurate, reliable and critically established text; The Introduction explains the work's genesis and its place in Reid's system; Annotations provide an understanding of Reid's context; An Appendix contains manuscript material covering an important topic not represented in the hitherto published work.

From the diverse work and often competing insights of women's human rights activists, Brooke Ackerly has written a feminist and a universal theory of human rights that bridges the relativists' concerns about universalizing from particulars and the activists' commitment to justice. Unlike universal theories that rely on shared commitments to divine authority or to an 'enlightened' way of reasoning, Ackerly's theory relies on rigorous methodological attention to difference and disagreement. She sets out human rights as at once a research ethic, (...) a tool for criticism of injustice and a call to recognize our obligations to promote justice through our actions. This book will be of great interest to political theorists, feminist and gender studies scholars and researchers of social movements. (shrink)

In Political Theory and Feminist Social Criticism, Brooke Ackerly demonstrates the shortcomings of contemporary deliberative democratic theory, relativism and essentialism for guiding the practice of social criticism in the real, imperfect world. Drawing theoretical implications from the activism of Third World feminists who help bring to public audiences the voices of women silenced by coercion, Brooke Ackerly provides a practicable model of social criticism. She argues that feminist critics have managed to achieve in practice what other theorists do only incompletely (...) in theory. Complemented by Third World feminist social criticism, deliberative democratic theory becomes critical theory - actionable, coherent, and self-reflective. While a complement to democratic theory, Third World feminist social criticism also addresses the problem in feminist theory associated with attempts to deal with identity politics. Third World feminist social criticism thus takes feminist theory beyond the critical impasse of the tension between anti-relativist and anti-essentialist feminist theory. (shrink)

In this paper we question whether the concept of "genetic privacy" is a contradiction in terms. And, if so, whether the implications of such a conclusion, inevitably impact on how society comes to perceive privacy and responsibility generally. Current law and ethical discourse place a high value on self-determination and the rights of individuals. In the medical sphere, the recognition of patient "rights" has resulted in health professionals being given clear duties of candour and frankness. Dilemmas arise, however, when patients (...) decline to know relevant information or, knowing it, refuse to share it with others who may also need to know. This paper considers the notions of interconnectedness and responsibility to others which are brought to the fore in the genetic sphere and which challenge the primacy afforded to personal autonomy. It also explores the extent to which an individual's perceived moral obligations can or should be enforced. (shrink)

Stem cell research has important implications for medicine. The source of stem cells influences their therapeutic potential, with stem cells derived from early-stage embryos remaining the most versatile. Somatic cell nuclear transfer (SCNT), a source of embryonic stem cells, allows for understandings about disease development and, more importantly, the ability to yield embryonic stem cell lines that are genetically matched to the somatic cell donor. However, SCNT requires women to donate eggs, which involves injection of ovulation-inducing hormones and egg retrieval (...) through laparoscopy or transvaginal needle aspiration. Risks from this procedure are fiercely debated, most notably risk of ovarian hyperstimulation syndrome (OHSS). This review examines risk of OHSS resulting from oocyte donation. We conclude that risk posed by OHSS in egg donation is not significant enough to warrant undue concern, and much of this can be eliminated when proper precautions are taken. This bears relevance to the future of stem cell research policymaking. (shrink)

Members of the Y‐box (YB) family of transcription factors are expressed in a wide range of cell types and are implicated in the regulation of a rapidly increasing number of genes. Although the biological activities of YB proteins appear to be varied, distinct patterns, relating to the timing of their expression and the identity of their target genes, are beginning to emerge. A recent report by Ito et al.(1) focusses attention on cell proliferation and adds support to earlier suggestions(2, 3) (...) that a primary function of YB proteins is to help activate growth‐associated genes.

Thomas Hobbes argued for absolute sovereignty, and claimed that in Christian countries the sovereign was fully empowered to govern the church as well as the state. There are grounds for seeing Hobbes as a staunch opponent of religious toleration, and a number of scholars support some variation of this position. This chapter examines the case for and against the idea of the tolerant Hobbes, beginning with his views on the clergy, and the historical context of those views, especially in the (...) debates on church–state relations that preoccupied his English contemporaries. Hobbes noted that clerics were commonly funded by tithes, which were a tenth of the incomes of the laity to whom they catered. Many English Protestant supporters of toleration drew the line at tolerating Roman Catholicism. Hobbes contended that “there is Publique, and Private Worship”. The precept that states should establish the uniform, public worship of God stemmed, in his opinion, from reason and nature. (shrink)

Against the backdrop of a global pandemic, this study investigates how U.S. higher education leaders have centered their crisis management on values and guiding ethical principles. We conducted 55 in-depth interviews with leaders from 30 U.S. higher education institutions, with most leaders participating in two interviews. We found that crisis plans created prior to the COVID-19 pandemic were inadequate due to the long duration and highly uncertain nature of the crisis. Instead, higher education leaders applied guiding principles on the fly (...) to support their decision-making. If colleges and universities infuse shared values into their future crisis plans, they will not have to develop a moral compass on the fly for the next pandemic. This paper suggests the following somewhat universal shared values: engage in accuracy, transparency, and accountability; foster deliberative dialog; prioritize safety; support justice, fairness, and equity; and engage in an ethic of care. To navigate ethics tensions, leaders need to possess crisis-relevant expertise or ensure that such expertise is present among crisis management team members. Standing up formal ethics committees composed of diverse stakeholders also is instrumental in navigating tensions inherent in crises. The next pandemic is already on the horizon according to experts. Through infusing values into future crisis plans, higher education leaders can be confident that their responses will be grounded in their communities’ shared values. (shrink)

'Johann Sommerville's is an impeccable textbook. Simply written, it provides exposition of Hobbes' arguments in the context of English and continental thought'. P. Springborg, University of Sydney, Political Studies, Vol. XL1, No 2 6/93 Thomas Hobbes was probably the greatest of British political theorists. Too often commentators have failed to grasp his meaning because they have ignored the historical context in which he wrote.

By viewing Hobbes in his context, the book both clarifies his theories and illuminates European thinking at a critical stage in the development of modern political ideas. (shrink)

The division of labor has typically been portrayed as a complementary strategy in which men and women work on separate tasks to achieve a common goal of provisioning the family. In this paper, we propose that task specialization between female kin might also play an important role in women’s social and economic strategies. We use historic group composition data from a population of Western Desert Martu Aborigines to show how women maintained access to same-sex kin over the lifespan. Our results (...) show that adult women had more same-sex kin and more closely related kin present than adult men, and they retained these links after marriage. Maternal co-residence was more prevalent for married women than for married men, and there is evidence that mothers may be strategizing to live with daughters at critical intervals—early in their reproductive careers and when they do not have other close female kin in the group. The maintenance of female kin networks across the lifespan allows for the possibility of cooperative breeding as well as an all-female division of labor. (shrink)

Some people feel distressed reflecting on human extinction. Some people even claim that our efforts and lives would be empty and pointless if humanity becomes extinct, even if this will not occur for millions of years. In this essay, I will attempt to demonstrate that this claim is false. The desire for long-lastingness or quasi-immortality is often unwittingly adopted as a standard for judging whether our efforts are significant. If we accomplish our goals and then later in life conclude that (...) these accomplishments were of no significance, then this is a sign that the desire for long-lastingness has crept into our standards. By recognizing this, and refraining from adopting an unreasonable standard to judge whether our efforts are significant, it will be to our advantage. Then, when we look back on life from an external perspective that encompasses times after humanity has become extinct, we will not conclude that our efforts amounted to nothing. Rather, we will conclude that many people made significant accomplishments that made their lives and the lives of other people better than they would have been if their goals had never been pursued.

ABSTRACTThis symposium brings together normative and empirical scholars in dialogue on Brooke Ackerly’s innovative and compelling recent monograph, Just Responsibility. Contributors discuss the book’s distinctive grounded normative theory methodology, its arguments for how individuals can take appropriate responsibility for global structural injustices, and its potential for practical impact.

Maternal grandmothers play a key role in allomaternal care, directly caring for and provisioning their grandchildren as well as helping their daughters with household chores and productive labor. Previous studies have investigated these contributions across a broad time period, from infancy through toddlerhood. Here, we extend and refine the grandmothering literature to investigate the perinatal period as a critical window for grandmaternal contributions. We propose that mother-daughter co-residence during this period affords targeted grandmaternal effort during a period of heightened vulnerability (...) and appreciable impact. We conducted two focus groups and 37 semi-structured interviews with Himba women. Interviews focused on experiences from their first and, if applicable, their most recent birth and included information on social support, domains of teaching and learning, and infant feeding practices. Our qualitative findings reveal three domains in which grandmothers contribute: learning to mother, breastfeeding support, and postnatal health and well-being. We show that informational, emotional, and instrumental support provided to new mothers and their neonates during the perinatal period can aid in the establishment of the mother-infant bond, buffer maternal energy balance, and improve nutritional outcomes for infants. These findings demonstrate that the role of grandmother can be crucial, even when alloparenting is common and breastfeeding is frequent and highly visible. Situated within the broader anthropological and clinical literature, these findings substantiate the claim that humans have evolved in an adaptive sociocultural perinatal complex in which grandmothers provide significant contributions to the health and well-being of their reproductive-age daughters and grandchildren.

Across a wide variety of cultural settings, kin have been shown to play an important role in promoting women’s reproductive success. Patrilocal postmarital residence is a potential hindrance to maintaining these support networks, raising the question: how do women preserve and foster relationships with their natal kin when propinquity is disrupted? Using census and interview data from the Himba, a group of semi-nomadic African pastoralists, I first show that although women have reduced kin propinquity after marriage, more than half of (...) married women are visiting with their kin at a given time. Mobility recall data further show that married women travel more than unmarried women, and that women consistently return to stay with kin around the time of giving birth. Divorce and death of a spouse also trigger a return to living with kin, leading to a cumulative pattern of kin coresidence across the lifespan. These data suggest that patrilocality may be less of a constraint on female kin support than has been previously assumed. (shrink)

Oxidised bases, such as 8-oxo-guanine, occur in cellular DNA as a result of attack by oxygen free radicals. The cancer-protective effect of vegetables and fruit is attributed to the ability of antioxidants in them to scavenge free radicals, preventing DNA damage and subsequent mutation. Antioxidant supplements (e.g., β-carotene, vitamin C) increase the resistance of lymphocytes to oxidative damage, and a negative correlation is seen between antioxidant concentrations in tissues and oxidised bases in DNA. Large-scale intervention trials with β-carotene have, however, (...) led to increases in cancer. Recent measurements of the frequency of oxidised DNA bases indicate that earlier estimates were greatly exaggerated; there may be only a few thousand 8-oxo-guanines per cell. Convincing evidence for mutations resulting from oxidative damage, in tumours or cultured cells, is lacking. It seems that efficient antioxidant defences together with DNA repair maintain a steady-state level of damage representing minimal risk to cell or organism.

This paper arises out of the transition from a PhD thesis on Heidegger's phenomenology to my attempts to come to terms with ‘becoming a teacher’. The paper will provide a phenomenological interpretation of being a teacher in relation to the question of an ‘authentic’ interpretation of teaching/learning and the possibility of an authentic interpretative praxis. I will argue that being a teacher is a phenomenon of human existence which can be interpreted as a possible way of being with authentic and (...) inauthentic potentialities. This way of being is intrinsically linked to that of learning; of becoming human or becoming the authentic possibilities of being‐human. As such, the problem of being a teacher is primarily an ethical question (or a question of ɛτηοσ—dwelling); of who we are as humans and of how being a teacher engages with the in‐formation of the becoming of students as authentic human beings. This then leads to the problem of how a phenomenological interpretation of education can be applied or lived; of authenticity in teaching/learning and the possibilities of authentic learning environments (educational dwelling).

The mother–adult daughter relationship has been highlighted in both the social sciences and the public health literature as an important facet of social support networks, particularly as they pertain to maternal and child health. Evolutionary anthropologists also have shown positive associations between support from maternal grandmothers and various outcomes related to reproductive success; however, many of these studies rely on proximity as a surrogate measure of support. Here I present data from the Puerto Rican Maternal and Infant Health Survey (PRMIHS) (...) comparing geographic proximity of mother and daughter with a self-reported measure of mother-to-daughter support. These two measures were used to predict infant health outcomes as well as various measures of instrumental and emotional aid provided during pregnancy and after birth. Primary support was shown to have a positive effect across the analyses, whereas geographic proximity was associated with an increased risk of infant mortality and low birth weight as well as reduced odds of receiving support. This paradox was then examined using a combination variable that teased out the interactions of maternal support and proximity. Women who were geographically close to their mothers but who did not consider them a primary source of support had increased odds of infant death and low birth weight, and were less likely to receive either tangible or intangible forms of aid, while women whose mothers were both close and primary showed uniformly positive outcomes. These results place the role of propinquity within the larger context of social support and highlight the need for more detailed studies of social support within evolutionary anthropology. (shrink)

This article explores how anticipations of parenthood differentially affect the career aspirations and choices of women and men who have not had children. Drawing from in-depth interviews conducted separately with 60 coupled young adults, I find that women in my sample were disproportionately likely to think and worry about future parenthood in their imagined work paths. Moreover, women were more likely than men to alter or downshift their present-day career goals in anticipation of the changes in preferences and responsibilities that (...) accompany new parenthood. Because men were unlikely to engage in the mental work of anticipating parenthood, they were also free from its emotional and behavioral consequences. In this way, gendered anticipations of parenthood, which begin relatively early in an individual’s career path, are likely to play a key role in reproducing patterns of labor market inequality even before the real constraints of parenthood have set in.

In Poverty, Solidarity, and Poor-Led Social Movements, Monique Deveaux builds a political theory of poverty as relational and responsibility for injustice as solidaristic. Identifying the ways that poor-led movements have politically theorized and acted, Deveaux develops a theory of relational poverty that entails politicizing poverty which requires local-level organizing, consciousness-raising, resisting injustice and developing and demanding alternatives, and engaging in public debate and discourse. She goes on to argue that the praxis of poor-led movements reveals normative commitments to mutuality, deference (...) and deep listening, and risk taking. These enable movements of people in poverty to take on the injustice of poverty together across difference, privilege, and other obstacles to transformative (solidaristic) politics. Deveaux provides a mode for doing grounded normative theory (GNT) by relying on secondary literature. GNT is a methodology for doing political theory that destabilizes the epistemological authority of the political theory of the academy by treating lived experience – words and actions – as providing relevant text for analysis. The methodology is particularly important for theories related to justice. Deveaux demonstrates how this can be done with secondary sources thus enabling comprehensive engagement without avoiding burdening social movement actors with interviews or other modes of accommodating researchers.

There are eleven known manuscripts of Hobbes’s Elements of Law. As they divide on textual grounds into two groups, they are effectively two separate editions, employing two different texts. While two of the manuscripts apparently were Hobbes’s working copies, it also seems clear that he never definitively established the text of the Elements. There are reasons for thinking it unlikely that, as has been suggested, Hobbes intended the work to influence debate in the Short Parliament. More likely, he hoped his (...) patron, Newcastle, would transmit his principles to the monarch and his chief advisors. (shrink)

Despite being a seemingly straightforward moral concept (that all humans have certain rights by virtue of their humanity), human rights is a contested concept in theory and practice. Theorists debate (among other things) the meaning of “rights,” the priority of rights, whether collective rights are universal, the foundations of rights, and whether there are universal human rights at all. These debates are of relatively greater interest to theorists; however, a given meaning of “human rights” implies a corresponding theory of change (...) and through that can be an important guide to the practice of human rights activists and their funders. In practice, any organization can describe their work as “rights based.” This article clarifies the practices of human rights activists and their funders that are consistent with a theory of human rights as (1) universal, (2) interdependent across groups and categories of people, (3) indivisible across issue areas and claims, and (4) measured by the enjoyment of rights.
