Data from the Kipsigis of Kenya are used to test two models for how parents invest in offspring, the Trivers-Willard and local resource competition/enhancement hypotheses. Investment is measured as age-specific survival, educational success, marital arrangements, and some components of property inheritance, permitting an evaluation of how biases persist or alter over the period of dependence. Changes through time in such biases are also examined. Despite stronger effects of wealth on the reproductive success of men than women, the survival of sons (...) and daughters is not related to parental wealth. However, a Trivers-Willard effect characterizes educational investment: poor families show a greater concern for daughters’ (vis-à-vis sons’) schooling than do rich families, a trend that has increased over time. In regard to models of local resource competition and enhancement, men’s reproductive success decreases with number of brothers and increases with number of sisters; this pattern of competition with same-sex sibs and cooperation with opposite-sex sibs is not found among women. As predicted from these observations, parents show reduced investment in sons with a large number of brothers, and increased investment in sons with a large number of sisters. By contrast, investment in daughters is entirely unaffected by number of sisters and is influenced only in subtle ways by number of brothers. Levels of investment in relation to sibship size (irrespective of siblings’ sex) are highest for younger children of large sib sets.Discussion of the results in relation to those from other studies leads to three conclusions. First, predictive models for how investment biases vary across societies must consider a broad range of socioecological factors constraining parental options and payoffs. Second, the timing of investment biases within societies will be affected by the value of children and the costs of parental investment. Third, measures of investment appropriate for between-sex and between-class comparisons need careful attention. Each of these issues is brought to bear on the question of why, in contrast to so many other parts of the world, sex preferences are so muted in Africa. (shrink)

Tracing the historical roots of modern conservation thought & practice, this book explores current perspectives from evolutionary & community ecology, conservation biology, anthropology, political ecology, economics, and policy.

Both behavioral ecological and social anthropological analyses of polygynous marriage tend to emphasize the importance of competition among men in acquisition of mates, whereas the strategic options to women both prior to and after the establishment of a marriage have been neglected. Focusing on African marriage systems that are in some senses analogous to resource-defense polygyny, I first review the evidence of reproductive costs of polygyny to women. Then I discuss why the conflict of interests between men and women over (...) mate number is often likely to be settled in favor of men. Using East African ethnographic data I examine the strategic responses of women and their families to polygynous marriage, focusing on four topics: mate choice (Kipsigis), attitudes toward incoming wives (Kipsigis), labor allocation and cooperation (comparative data, Kipsigis), and use of parental wealth (Datoga). The results of these quantitative analyses suggest that through a combination of judicious marriage choice and strategic responses within marriage, polygyny need not be costly to women in resource-defense polygynous systems. The conclusion is that a hierarchy of questions need to be addressed in the analysis of any polygynous marriage system. (shrink)

Applications of sexual selection theory to humans lead us to expect that because of mammalian sex differences in obligate parental investment there will be gender differences in fitness variances, and males will benefit more than females from multiple mates. Recent theoretical work in behavioral ecology suggests reality is more complex. In this paper, focused on humans, predictions are derived from conventional parental investment theory regarding expected outcomes associated with serial monogamy and are tested with new data from a postreproductive cohort (...) of men and women in a primarily horticultural population in western Tanzania (Pimbwe). Several predictions derived from the view that serial monogamy is a reproductive strategy from which males benefit are not supported. Furthermore, Pimbwe women are the primary beneficiaries of multiple marriages. The implications for applications of sexual selection theory to humans are discussed, in particular the fact that in some populations women lead sexual and reproductive lives that are very different from those derived from a simple Bateman-Trivers model.

What are the driving forces of cultural macroevolution, the evolution of cultural traits that characterize societies or populations? This question has engaged anthropologists for more than a century, with little consensus regarding the answer. We develop and fit autologistic models, built upon both spatial and linguistic neighbor graphs, for 44 cultural traits of 172 societies in the Western North American Indian (WNAI) database. For each trait, we compare models including or excluding one or both neighbor graphs, and for the majority (...) of traits we find strong evidence in favor of a model which uses both spatial and linguistic neighbors to predict a trait’s distribution. Our results run counter to the assertion that cultural trait distributions can be explained largely by the transmission of traits from parent to daughter populations and are thus best analyzed with phylogenies. In contrast, we show that vertical and horizontal transmission pathways can be incorporated in a single model, that both transmission modes may indeed operate on the same trait, and that for most traits in the WNAI database, accounting for only one mode of transmission would result in a loss of information.

The analogy between biological and cultural evolution is not perfect. Yet, as Mesoudi et al. show, many of the vaunted differences between cultural and genetic evolution (for example, an absence of discrete particles of cultural inheritance, and the blurred distinction between cultural replicators and cultural phenotypes) are, on closer inspection, either illusory or peripheral to the validity of the analogy. But what about horizontal transmission? We strongly agree with the authors that the potential for horizontal transmission of cultural traits does (...) not invalidate an evolutionary approach to culture. We suggest, however, that it does require a different evolutionary treatment. (Published Online November 9 2006). (shrink)

Biology and the social sciences share an interest in phylogeny. Biologists know that living species are descended from past species, and use the pattern of similarities among living species to reconstruct the history of phylogenetic branching. Social scientists know that the beliefs, values, practices, and artifacts that characterize contemporary societies are descended from past societies, and some social science disciplines, linguistics and cross cultural anthropology for example, have made use of observed similarities to reconstruct cultural histories. Darwin appreciated that his (...) theory of descent with modification had many similarities of pattern and process to the already well developed field of historical linguistics. In many other areas of social science, however, phylogenetic reconstruction has not played a central role. (shrink)

Although the word empathy only recently came into existence, eighteenth century philosopher, David Hume, significantly contributed to our current understanding of the term. Hume was among the first to suggest that an empathic mechanism is the central means by which we make ethical judgments and glean moral knowledge. In this paper, I explore Hume's moral sentimentalism, and I argue that his conception of empathy provides a surprisingly apposite framework for interpreting and addressing a current issue in practical ethics: the moral (...) significance of ultra-violent video games. Ultimately, I attempt to show that a Humean account of morality uniquely explains the dangers of ultra-violent video gaming by elucidating a direct connection between playing such games and moral harm.

There have been and continue to be disagreements about how to consider the traditional square of opposition and the traditional inferences of obversion, conversion, contraposition and inversion from the perspective of contemporary quantificational logic. Philosophers have made many different attempts to save traditional inferences that are invalid when they involve empty classes. I survey some of these attempts and argue that the only satisfactory way of saving all the traditional inferences is to make the existential assumption that both the subject (...) and predicate classes and their complement classes are non-empty for all the propositions we admit. I briefly indicate the room for continued controversy over how properly to interpret Aristotle's statements regarding these inferences, but find some plausibility in the views of Manley Thompson and A.N.Prior that Aristotle had in mind a particular arrangement of existential import unfamiliar to most contemporary logicians.

Life poses a threat to materialism. To understand the phenomena of animate nature, we make use of a teleological form of explanation that is peculiar to biology, of explanations in terms of what I call the ‘vital categories’ – and this holds even for accounts of underlying physico-chemical ‘mechanisms’. The materialist claims that this teleological form of explanation does not capture what is metaphysically fundamental, whereas her preferred physical form of explanation does. In this essay, I do three things. (1) (...) I argue that the ‘vital categories’, such as life form and life-process, do not reduce to the ‘physical categories’ and show that there are no grounds for the materialist's metaphysically limiting claim; (2) I sketch a positive view on how vital and physical explanations can both apply to a given phenomenon, and on how they interrelate; and (3) I show that this view meshes nicely with evolutionary theory, despite being committed to a form of ‘biological essentialism’.

This symposium on Monique Deveaux’s Poverty, Solidarity, and Poor-Led Social Movements includes commentaries by Sally Matthews, Renante D. Pilapil, Violetta Igneski, and Wouter Peeters, with a reply from Deveaux. The book makes the case that normative thinking about poverty should engage closely with the aims, insights, and actions of poor-led organizations and social movements. Challenging conventional framings of poverty by moral philosophers, Deveaux argues that chronic poverty is centrally about the subordination and dispossession of the poor – not mere (...) needs scarcity. To exclude people living in poverty from shaping antipoverty solutions is therefore to perpetuate their social-political domination and epistemic oppression. Deveaux’s book explains what a political reframing of poverty looks like from the vantage point of several poor-led organizations and social movements, using concrete examples from across the globe, and argues for political responsibility for solidarity with those movements.

Political philosophers’ prescriptions for poverty alleviation have overlooked the importance of social movements led by, and for, the poor in the global South. I argue that these movements are normatively and politically significant for poverty reduction strategies and global justice generally. While often excluded from formal political processes, organized poor communities nonetheless lay the groundwork for more radical, pro-poor forms of change through their grassroots resistance and organizing. Poor-led social movements politicize poverty by insisting that, fundamentally, it is caused by (...) social relations of power that exploit and subordinate poor populations. These movements and their organizations also develop the collective capabilities of poor communities in ways that help them to contest the structures and processes that perpetuate their needs deprivation. I illustrate these contributions through a discussion of the Landless Rural Worker’s Movement in Brazil (the MST), a poor mobilization organization in Bangladesh (Nijera Kori), and the slum and pavement dweller movement in India. Global justice theorizing about poverty cannot just “add on” the contributions of such struggles to existing analyses of, and remedies for, poverty, however; rather, we will need to shift to a relational approach to poverty in order to see the vital importance of organized poor communities to transformative, poor-centered poverty reduction.

Recent research emphasizes the complexity of providing useful explanations of computer-generated output. In developing an explanation-generating tool, the computer scientist should take a user-centered perspective, while taking into account the user’s susceptibility to certain biases. The purpose of this paper is to expand the research results on explainability from the social sciences, and to indicate how these results are relevant to the field of XAI. This is done through the presentation of two surveys to university students. The analysis of the (...) results leads to some interesting hypotheses, for example that the presented order of historical facts might be more influential on the interpretation or appreciation of an event than the actual temporal order of these facts. The computer scientist should, therefore, pay particular emphasis to the format of the produced output of any explainable artificial intelligence system. The main message of the paper is that results from the social sciences must be regarded as a crucial foundation of any explainable artificial intelligence system. (shrink)

Baselines are commonly used to enable harm identification. The temporal, the counterfactual and the duty-based normative baselines are the most prominent. Each of these captures an aspect of common conceptions of what it is to harm and be harmed. However, each baseline also fails to deliver workable identifications of harm when presented with certain types of case. Problematic cases are found readily in childhood, a venue in which harm identification is often called for. Without a reliable means of identifying harm (...) in childhood, harm cannot properly play a central role in normative assessments of parental practices and state intervention. This paper presents childhood cases in which the prominent baselines fail and offers an alternative: the interest-based normative baseline. Should the interest-based normative baseline replace its rivals and reign supreme? I argue not, presenting a case for maintaining a suite of baselines for use in varying contexts. (shrink)

Although contemporary powers metaphysics largely understands itself as a metaphysical realist undertaking, recently powers have come to the surface also within an idealist context. This paper aims to characterize and motivate an absolute idealist conception of powers. I compare realist and idealist powers metaphysics in their respective responses to Humean scepticism concerning powers, thereby motivating the claim that the very idea of a power is actually best understood as an idealist idea. I continue to characterize the absolute idealist’s understanding of (...) power, for which it is necessary to see that the content of her power notion is inseparable from the way in which she arrives at that notion. I close with a brief reflection on the absolute idealist’s understanding of the power of thought, which is where idealist and realist powers metaphysics diverge most radically. (shrink)

Humeans take reality to be devoid of ‘necessary connections’: things just happen. Laws of nature are to be understood in terms of what ‘just happens’, not vice versa. Here the Humean needs some conception of what it is that ‘just happens’ – a conception of the Humean mosaic. Lewis’s Humeanism incorporates such a conception in the form of a Lewis-style metaphysics of objects, properties, and modality. Newer versions of Humeanism about laws of nature, such as the Better Best Systems approach, (...) typically reject such a Lewisian metaphysics, but it remains unclear what they can offer in its place. By exploring different candidate conceptions, this paper sheds light on the limits of Humeanism about laws of nature: not all conceptions of the Humean mosaic form a suitable basis for a Humean theory of laws. In fact, only a metaphysics roughly in line with Lewis’s will do. The paper ends with a tentative generalization of this result, thus pointing to the ‘limit’ of Humeanism in general: taking the Humean way of thinking to its limit results in a rejection of the whole idea of such a mosaic – and hence of Humean mosaic-based accounts of anything.

The brain adapts to changes that take place in the body. Deprivation of input results in size reduction of cortical representations, whereas an increase in input results in an increase of representational space. Amputation forms one of the most dramatic disturbances of the integrity of the body. The brain adapts in many ways to this breakdown of the afferent–efferent equilibrium. However, almost all studies focus on the sensorimotor consequences. It is not known whether adaptation takes place also at other “levels” (...) in the system. The present study addresses the question whether amputees dream about their intact body, as before the amputation, or about the body after the amputation and whether the dream content was a function of time since the amputation and type of amputation. The results show that the majority of the dreamers reported dreams about their intact body although the mean time that elapsed since the amputation was twelve years. There is no clear relation with the type of amputation. The results give modest evidence for the existence of a basic neural representation of the body that is, at least, partly genetically determined and by this relatively insensitive for changes in the sensory input.

Ex aequo et bono compensations refer to tribunal’s compensations that cannot be determined exactly according to the rule of law, in which case the judge relies on an estimate that seems fair for the case at hand. Such cases are prone to legal uncertainty, given the subjectivity that is inherent to the concept of fairness. We show how basic principles from statistics and machine learning may be used to reduce legal uncertainty in ex aequo et bono judicial decisions. For a (...) given type of ex aequo et bono dispute, we consider two general stages in estimating the compensation. First, the stage where there is significant disagreement among judges as to which compensation is fair. In that case, we let judges rule on such disputes, while a machine tracks a certain measure of the relative differences of the granted compensations. In the second stage that measure, which expresses the degree of legal uncertainty, has dropped below a predefined threshold. From then on legal decisions on the quantity of the ex aequo et bono compensation for the considered type of dispute may be replaced by the average of previous compensations. The main consequence is that this type of dispute is, from this stage on, free of legal uncertainty. (shrink)

In this paper I consider Kierkegaard’s pseudonymous attack on natural theology with respect to how it lines up with Catholic thought on that topic. I argue that Kierkegaard’s recently shown similarities to accounts of basic beliefs raise an interesting question when a Catholic hybrid of basic beliefs and natural theology, which I develop in the paper, is considered. Kierkegaard does not attack what we might call natural reason, or a natural awareness of God’s existence, only natural theology’s demonstrative capabilities, and (...) his reasons for doing the latter, in our current epistemological climate, are shown to be mistaken.

All media begin as a potential in our bodies, expand into the public domain, creating a world – and finally end again in the body, as a way of being, a range of feeling, a belief system. Media theory studies this trajectory. For media theory, media have two limits. Media cannot, by definition, make contact with the extramedial (because, if they could, they would become intramedial). And when media are translated into software they lose their identity and become part of (...) something beyond media theory. (shrink)

In this paper, I consider how a Kierkegaardian could respond critically to the question of strong theological universalism, i.e., the belief that all individuals must eventually be reconciled to God and experience everlasting happiness. A Kierkegaardian would likely reject what Thomas Talbott has called “conservative theism,” but has the resources to mount a sustained attack on the view that all individuals must experience everlasting happiness. Some have seen that Kierkegaard has some potential in this regard, but a full Kierkegaardian response (...) to strong theological universalism has yet to be given. In this paper, I give such an account. (shrink)

The concepts “dispositive” and “intermediality” emerged at the same time and are becoming increasingly prominent. In this article, I propose to consider what intermediality brings to the dispositive, based on a case study of the diptych El Otro Lado de la Cama and Los Dos Lados de la Cama, two mainstream films from contemporary Spain in the early twenty-first century. Dispositive theory has been developed in France by academics working in the fields of modern literature and theater at the University (...) of Toulouse, notably Marie-Thérèse Mathet, Stéphane Lojkine, Philippe Ortel and Arnaud Rykner. In the late 1990s, this group adapted Foucault’s concept of the dispositive 2 to the fields of literature and.. (shrink)

In the present research we investigated gender-specific beliefs about emotional behaviour. In Study 1, 180 respondents rated the extent to which they agreed with different types of beliefs (prescriptive, descriptive, stereotypical, and contra-stereotypical) regarding the emotional behaviour of men and women. As anticipated, respondents agreed more with descriptive than with prescriptive beliefs, and more with stereotypical than with contra-stereotypical beliefs. However, respondents agreed more with stereotypical beliefs about the emotional behaviour of women than with those about men. These results were (...) replicated in Study 2 with a sample of 75 students and 80 nonstudents. In Study 3, a sample of 279 respondents rated the extent of agreement with the same items, this time with respect to then own emotional behaviour. A similar pattern of results was obtained, although agreement rates were higher than in Study 1 and 2. (shrink)

Xenotransplantation is defined as “any procedure that involves the transplantation, implantation, or infusion into a human recipient of either live cells, tissues, or organs from a nonhuman animal source, or human body fluids, cells, tissues or organs that have had ex vivo contact with live nonhuman animal cells, tissues, or organs.” Xenotransplantation has been viewed by desperate patients and their surgeons as a solution to the problem of the paucity of human organs available for transplantation. Foes of xenotransplantation argue that (...) the use of animal organs degrades the human race and should be avoided.In this paper, we briefly review the cultural context of xenotransplantation and explore the infectious disease risk of xenotransplantation. The United States Code of Federal Regulations requires life-long surveillance of a xenotransplantation recipient due to the largely unknown risk of novel infectious disease transmitted across species, known as xenogeneic infectious disease. We argue that despite being in the interest of protecting the public health, the imposition of lifelong surveillance requirements on xenotransplant recipients effectively abrogates the right to withdraw from a clinical trial after the transplantation has taken place. Moreover, we argue that a waiver of the right to withdraw should be made explicit in the interest of full disclosure, out of respect for the research subject’s right of self-determination. (shrink)

In 2017 and 2018, the English courts were asked to decide whether continued life‐sustaining treatment was in the best interests of three infants: Charlie Gard, Alfie Evans and Isaiah Haastrup. Each infant had sustained catastrophic, irrecoverable brain damage. Dignity played an important role in the best interests assessments reached by the Family division of the High Court in each case. Multiple conceptions of dignity circulate, with potentially conflicting implications for infants such as Charlie, Alfie and Isaiah. The judgements do not (...) explicate the conceptions of dignity upon which they rely. This article reconstructs the conceptions of dignity invoked in these judgements, finding that a broadly Kantian, agential conception dominates, under which human dignity requires the prospect of agency. This conception is situated within the broader body of thought on dignity, and the potentially adverse implications of applying the reconstructed conception in best interests assessments for infants with severely restricted consciousness are discussed.

“Agent-centered” approaches to global poverty insist that effective arguments for poverty reduction must specify the concrete duties of particular duty-bearers. This article takes up a recent, influential, version of this view, Thomas Pogge’s human rights-based argument for global economic reforms to reduce chronic deprivation. While signaling a welcome shift from the diffuse allocation of responsibilities common to much philosophical writing on poverty, I argue that Pogge’s approach too readily assigns to powerful institutions in the global North the role of devising (...) and directing anti-poverty initiatives. In so doing, he overlooks the agency—actual and potential—of the poor themselves, as evidenced by poor-led political movements and poor-centered, participatory models of poverty reduction in development theory and practice. While agent-oriented approaches are right to focus our attention on structures that cause poverty, they ought not to assume that the powerful agents responsible for these are the only—or most appropriate—agents to lead the way to poverty reduction. Just as development organizations working in the global South have come to recognize that the participation of poor communities is critical to the success of development strategies, so should normative theorists writing about global injustice acknowledge the importance of the poor as active agents in poverty reduction efforts.

The most basic divide amongst analytic metaphysicians separates realists from anti-realists. By examining certain characteristic and problematic features of these two families of views, we uncover their underlying metametaphysicalorientations, which turn out to coincide. This shared philosophical picture that underlies both the realist and the anti-realist project we call the Modern Picture. It rests on a crucial distinction between reality as it is for us and reality as it is in itself. It is argued that this distinction indeed generates the (...) realism/anti-realism dichotomy, and is also responsible for the problematic aspects highlighted earlier. We conclude by sketching an alternative philosophical picture that rejects the distinction between reality as it is for us and reality as it is in itself, which we call the Aristotelian Picture, and consider whether it is able to avoid the issues to which the Modern Picture gives rise.

Monique Roelofs offers a pathbreaking systematic model of the field of address and puts it to work in the arts, critical theory, and social life. She shows how address props up finely hewn modalities of relationality, agency, and normativity. Address exceeds a one-on-one pairing of cultural productions with their audiences. As ardently energizing tiny slippages and snippets as fueling larger impulses in the society, it activates and reaestheticizes registers of race, gender, class, coloniality, and cosmopolitanism. In readings of writers (...) and artists ranging from Julio Cortázar to Jamaica Kincaid and from Martha Rosler to Pope.L, Roelofs demonstrates the centrality of address to freedom and a critical political aesthetics. Under the banner of a unified concept of address, Hume, Kant, and Foucault strike up conversations with Benjamin, Barthes, Althusser, Fanon, Anzaldúa, and Butler. Drawing on a wide array of artistic and theoretical sources and challenging disciplinary boundaries, the book illuminates address's significance to cultural existence and to our reflexive aesthetic engagement in it.

The term “emotional practices” is gaining currency in the historical study of emotions. This essay discusses the theoretical and methodological implications of this concept. A definition of emotion informed by practice theory promises to bridge persistent dichotomies with which historians of emotion grapple, such as body and mind, structure and agency, as well as expression and experience. Practice theory emphasizes the importance of habituation and social context and is thus consistent with, and could enrich, psychological models of situated, distributed, and (...) embodied cognition and their approaches to the study of emotion.It is suggested here that practices not only generate emotions, but that emotions themselves can be viewed as a practical engagement with the world. Conceiving of emotions as practices means understanding them as emerging from bodily dispositions conditioned by a social context, which always has cultural and historical specificity. Emotion-as-practice is bound up with and dependent on “emotional practices,” defined here as practices involving the self , language, material artifacts, the environment, and other people. Drawing on Pierre Bourdieu's concept of habitus, the essay emphasizes that the body is not a static, timeless, universal foundation that produces ahistorical emotional arousal, but is itself socially situated, adaptive, trained, plastic, and thus historical. Four kinds of emotional practices that make use of the capacities of a body trained by specific social settings and power relations are sketched out—mobilizing, naming, communicating, and regulating emotion—as are consequences for method in historical research.

It is not uncommon for philosophers to name disinterestedness, or some like feature, as an essential characteristic of love. Such theorists claim that in genuine love, one’s concern for her beloved must be non-instrumental, non-egocentric, or even selfless. These views prompt the question, “What, if any, positive role might self-interestedness play in genuine love?” In this paper, I argue that attachment, an attitude marked primarily by self-focused emotions and emotional predispositions, helps constitute the meaning and import of at least some (...) kinds of adult reciprocal love. In this way, attachment represents a type of self-interestedness that not only contributes positively to such relationships but is also essential to them. (shrink)
