Despite decades of research, we still lack a clear explanation for the emergence and persistence of inequality. Here we propose and evaluate a marginal utility of inequality hypothesis that nominates circumscription and environmental heterogeneity as independent, necessary conditions for the emergence of intragroup material inequality. After coupling the Standard Cross-Cultural Sample with newly generated data from remote sensing, we test predictions derived from this hypothesis using a multivariate generalized additive model that accounts for spatial and historical dependence as well as (...) subsistence mode. Our analyses show that the probability a society will be stratified increases significantly as a function of proxies of environmental heterogeneity and environmental circumscription. This supports the hypothesis that increasing environmental heterogeneity and circumscription drives the emergence and persistence of inequality among documented societies across the globe. We demonstrate how environmental heterogeneity and circumscription produce situations that limit individuals’ options so that some may find it in their best interest to give up some autonomy for material gain, while others may find it in their best interest to give up some material resources for another individual’s time or deference. These results support the marginal utility of inequality framework and enable future explorations of the ecological conditions that facilitate the emergence of intragroup inequality through time and across the globe.

Henrich et al.'s nice cross-cultural experiments would benefit from models that specify the decision rules that humans use and the specific developmental pathways that allow cooperative norms to be internalized. Such models could help researchers to design further experiments to examine human social adaptations. We must also test whether the “same” experiments measure similar constructs in each culture, using additional methods and measures.

War and Border Crossings brings together renowned scholars to address some of the most pressing problems in public policy, international affairs, and the intercultural issues of our day. Contributors from widely varying disciplines discuss cross-cultural ethical issues and international topics ranging from American international policy and the invasion and occupation of Iraq to domestic topics such as immigration, the war on drugs, cross-cultural bioethics and ethical issues involving American Indian tribes. The culture clashes discussed in these essays raise serious questions (...) about what principles ought to inform the negotiating of conflicts in order to achieve, or at least approach, outcomes that are fundamentally just, fair, responsible, and ethical.

This paper is a critique of some ideas about narrow content owing to Horgan and Tienson and Brian Loar.

Darwin's theory of evolution by natural selection is considered in its application to human beings in this book. Brian Baxter examines the various sociobiological approaches to the explanation of human behaviour which view the human brain, and so the human mind, as the product of evolution, and considers the main arguments for and against this claim. In so doing he defends the approaches against some common criticisms, such as the charge that they are reductionist and dehumanising. The implications of (...) these arguments for the social sciences and humanities are assessed, as is the naturalistic view of ethics to which they lead. A key issue examined in the book is the connection between this Darwinist perspective on human beings and modern environmental ethics, which also often assume that human beings are part of an evolved living world. The implications of these positions for the meaningfulness of human life are also examined.Throughout the discussion, the positions in sociobiology and environmental ethics developed by Edward O Wilson are taken as an exemplar of the characteristic features of a Darwinian worldview, and the arguments of Wilson and his chief critics are thoroughly examined.

The contextual approach is a prominent framework for thinking about group selection. Here, I highlight ambiguity about what the contextual approach is. Then, I discuss problematic entailments the contextual approach has for what processes count as group selection—entailments more troublesome than typically noted. However, Sober and Wilson’s version of the Price approach, which is the main alternative to the contextual approach, is problematic too: it leads to an underappreciated paradox called the vanishing selection problem and thereby generates the wrong (...) qualitative account of whether group selection is occurring in a certain family of cases. In response, I develop an account of group selection that can deal with the counterexamples to both the contextual approach and the Price approach. I then discuss the role that contextual analysis can continue to play in the discussion of individual fitness and metapopulation evolution. (shrink)

This is a review of the biographic drama Love and Mercy. More than a story of the evolution of The Beach Boys, it is the story of the lead Beach Boy, Brian Wilson, and his struggle with substance abuse, mental illness, family stress, emerging love, and a controlling psychologist. Interwoven are many bioethics themes, including the doctor–patient relationship, conflict of interest, autonomy, and patient welfare. For those unaware of the sadness and torment running directly alongside the sunny, bubbly (...) life of The Beach Boys, this film is an eye-opener. It is also a great reminder of the importance of boundaries between clinicians and their patients. (shrink)

Prior to its publication, Gary Cox's MakingVotesCount was widely and eagerly anticipated. (Indeed, some years ago, I received a referee report dismissing my submission as unnecessary because superior analysis would eventually appear in Cox's then forthcoming manuscript.) Upon its release in 1998, the book was instantly lauded: it collected multiple awards, including the prestigious Woodrow Wilson prize for best book published on government, politics, or international affairs. This acclaim was scarcely surprising – Cox has been one of the foremost (...) scholars of elections and legislatures for the whole of his professional career. He is responsible for an impressive body of work spanning multiple research topics, nations, and methods of analysis. This book is testimony to his breadth, as it catalogs the key electoral features of virtually the whole set of modern democracies (more than 70), and makes frequent forays into diverse nations in search of empirical support for novel theoretical findings. In brief, Cox's project is to bring together a large formal, deductive literature on voting rules and social choice with an equally voluminous empirical, inductive literature on elections and party systems in the world's democracies. The prizes it garnered are one measure of the book's success at this merger; a large boost in Cox's swelling citation count will doubtless follow, reiterating the judgement that this is the major work on electoral law and voting to date.

A number of authors have combined a commitment to Darwinian evolution as a major source of insight into human nature with a strong commitment to environmentalist concerns. The most notable of these is perhaps Edward O. Wilson, in a series of books. Yet it may appear that there is a tension between Darwinism as a world-view – or least some major aspects of it – and a concern for non-human entities as worthy of concern in their own right. In (...) the present paper, I want to address some of the reasons for thinking there is such a tension. (shrink)

How does Sober-Wilson group selection explain the possibility of the evolution of altruism, as modeled by cooperation in the Prisoner’s Dilemma? The essential point is that if the parameters of the model are just right, group structure can generate positive correlation of interactions between cooperators. If positive correlation is strong enough, cooperation can evolve; if not it cannot. This is true whether the positive correlation is generated by a group selection model or in some other way.

In 1975 E. O. Wilson called for biologists to appropriate ethics.1 Few philosophers worried deeply about this potential usurpation because they felt firmly ensconced on the other side of the Humean wall from the biologists. Science can provide neither guidance nor values. Perhaps nowhere is this more clear than in the crowning question of ethics; namely, what is the meaning of life? Since evolution proposes an ateleological account of the natural world, biologists can dismiss the question to which we (...) all desperately want an answer as a category mistake. If pressed to understand the question metaphorically, biologists begrudgingly reply that the meaning of life is to get as much of your genetic material. (shrink)

An artistic discussion on the critical potential of African American expressive culture In a major reassessment of African American culture, Phillip Brian Harper intervenes in the ongoing debate about the “proper” depiction of black people. He advocates for African American aesthetic abstractionism—a representational mode whereby an artwork, rather than striving for realist verisimilitude, vigorously asserts its essentially artificial character. Maintaining that realist representation reaffirms the very social facts that it might have been understood to challenge, Harper contends that abstractionism (...) shows up the actual constructedness of those facts, thereby subjecting them to critical scrutiny and making them amenable to transformation. Arguing against the need for “positive” representations, Abstractionist Aesthetics displaces realism as the primary mode of African American representational aesthetics, re-centers literature as a principal site of African American cultural politics, and elevates experimental prose within the domain of African American literature. Drawing on examples across a variety of artistic production, including the visual work of Fred Wilson and Kara Walker, the music of Billie Holiday and Cecil Taylor, and the prose and verse writings of Ntozake Shange, Alice Walker, and John Keene, this book poses urgent questions about how racial blackness is made to assume certain social meanings. In the process, African American aesthetics are upended, rendering abstractionism as the most powerful modality for Black representation. (shrink)

Storytellers and their audiences over many millennia have thought that we can learn from fiction. Philosopher Gregory Currie challenges that supposition. He doubts knowing can be founded on imagining, and claims that what we think we learn from fiction is not reli­able in the way science or philosophy is, because not tested through peerreview, experi­ment, and argument. He underrates the role of the imagination in understanding all hu­man language, in fictionality outside formal fictions, and in science. Science is not “reliabilist” (...) as Currie assumes: it aims at bold imaginative discoveries that often overturn what had previously been thought secure and may well be displaced by still newer discov­eries. Fiction may not have peer review, but it is tested on the highly developed intuitions of audiences, on the expertise of critics, and through the corrective competition and inno­vations of other storytellers, as Joyce challenges Homer, or David Sloan Wilson’s recent Atlas Hugged challenges Ayn Rand’s Atlas Shrugged. There are strong reasons for predicting that fiction has a prosocial bias from which humans over many millennia have learned to expand their sociality. That does not mean that all exposure to fiction is beneficial. (shrink)

Ruth Leys raises a number of important questions about the conceptual and empirical underpinnings of the affect theories that have emerged in the critical humanities, sciences, and social sciences in the last decade. There are a variety of frameworks for thinking about what constitutes the affective realm , and there are different preferences for how such frameworks could be deployed. We would like to engage with just one part of that debate: the contributions of Silvan Tomkins's affect theory. We take (...) issue with Leys's formulation that Tomkins's work along with that of Brian Massumi, William Connolly, and Paul Ekman form a group of like-minded theorists. We do not believe this represents an accurate account of the conceptual and empirical commitments of these various authors. By bundling their work together, Leys misses much of what is compellingly critical in each of these writers, and she overlooks what is most invigorating in the debates amongst them. In addition, the specificities of Tomkins's work have been badly served in Leys's essay. In four volumes stretching from 1962 to 1992 Tomkins laid out a complex and captivating theory of the human affect system, in which mechanisms of neurological feedback, social scripts, and facial behavior coassemble as affective events. Our response to Leys's essay is motivated by a wish to see more detailed engagements with this theory—the distinctiveness of which we believe has yet to be fully explored in this new affective turn.

Four principal papers and a total of 43 peer commentaries on the evolutionary origins of morality. To what extent is human morality the outcome of a continuous development from motives, emotions and social behaviour found in nonhuman animals? Jerome Kagan, Hans Kummer, Peter Railton and others discuss the first principal paper by primatologists Jessica Flack and Frans de Waal. The second paper, by cultural anthropologist Christopher Boehm, synthesizes social science and biological evidence to support his theory of how our hominid (...) ancestors became moral. In the third paper philosopher Elliott Sober and evolutionary biologist David Sloan Wilson argue that an evolutionary understanding of human nature allows sacrifice for others and ultimate desires for another's good. Finally Brian Skyrms argues that game theory based on adaptive dynamics must join the social scientist's use of rational choice and classical game theory to explain cooperation. (shrink)

In three experiments, subjects attempted to track multiple items as they moved independently and unpredictably about a display. Performance was not impaired when the items were briefly (but completely) occluded at various times during their motion, suggesting that occlusion is taken into account when computing enduring perceptual objecthood. Unimpaired performance required the presence of accretion and deletion cues along fixed contours at the occluding boundaries. Performance was impaired when items were present on the visual field at the same times and (...) to the same degrees as in the occlusion conditions, but disappeared and reappeared in ways which did not implicate the presence of occluding surfaces (e.g. by imploding and exploding into and out of existence, instead of accreting and deleting along a fixed contour). Unimpaired performance did not require visible occluders (i.e. Michotte’s tunnel effect) or globally consistent occluder positions. We discuss implications of these results for theories of objecthood in visual attention. (shrink)

As anyone who has flown out of a cloud knows, the boundaries of a cloud are a lot less sharp up close than they can appear on the ground. Even when it seems clearly true that there is one, sharply bounded, cloud up there, really there are thousands of water droplets that are neither determinately part of the cloud, nor determinately outside it. Consider any object that consists of the core of the cloud, plus an arbitrary selection of these droplets. (...) It will look like a cloud, and circumstances permitting rain like a cloud, and generally has as good a claim to be a cloud as any other object in that part of the sky. But we cannot say every such object is a cloud, else there would be millions of clouds where it seemed like there was one. And what holds for clouds holds for anything whose boundaries look less clear the closer you look at it. And that includes just about every kind of object we normally think about, including humans. Although this seems to be a merely technical puzzle, even a triviality, a surprising range of proposed solutions has emerged, many of them mutually inconsistent. It is not even settled whether a solution should come from metaphysics, or from philosophy of language, or from logic. Here we survey the options, and provide several links to the many topics related to the Problem. (shrink)

It is argued that propositions cannot be the compositional semantic values of sentences (in context) simply due to issues stemming from the compositional semantics of modal operators (or modal quantifiers). In particular, the fact that the arguments for double indexing generalize to multiple indexing exposes a fundamental tension in the default philosophical conception of semantic theory. This provides further motivation for making a distinction between two sentential semantic contents—what (Dummett 1973) called “ingredient sense” and “assertoric content”.

Higher-order evidence is evidence about what is rational to think in light of your evidence. Many have argued that it is special – falling into its own evidential category, or leading to deviations from standard rational norms. But it is not. Given standard assumptions, almost all evidence is higher-order evidence.

In education, we are concerned with the teaching and learning of subjects, but the word “subject” can refer to the discipline being studied as well as the individual who is studying. In this essay, Teresa Strong-Wilson explores this “double entendre” of curriculum studies through the analogy afforded by German author-in-exile W. G. Sebald's working through of difficult subjects by way of semi-autobiographical writing that takes the form of an “invisible subject”: a preoccupation with an unnamed injustice entangled with his (...) own upbringing. Curriculum theory, as currere, has foregrounded the autobiographical. While the place of autobiography in curriculum studies has often been taken to mean writing, currere is more an allegorical method of study, of intellectual engagement, of learning through reading and writing, and of teaching so as to open spaces for agency. Strong-Wilson suggests that Sebald can provide a strong example for us in curriculum studies of how to ethically bring into being an allegorical, autobiographical practice focused on “invisible” subjects of deep concern.

This chapter focuses specifically on the case of pain. Despite traditional opposition to the representational thesis, the latter has won widespread assent. The most important early proponents of the representational thesis were David Armstrong and George Pitcher, both of whom held that pain is a form of perception. Following Armstrong and Pitcher, intentionalists have traditionally held that the experience of pain has a content with roughly the following form: there is a disturbance with such-and-such features at location L. Since the (...) internal states associated with the experience of pain arguably track local physical properties of disturbances, it seems that the tracking intentionalist must identify the pain qualities represented by pain experience with these physical properties. But there are at least two important objections to the identification of pain qualities with local physical properties of disturbances. (shrink)

Consciousness often presents itself as a problem for materialists because no matter which physical explanation we consider, there seems to remain something about conscious experience that hasn't been fully explained. This gives rise to an apparent explanatory gap. The explanatory gulf between the physical and the conscious is reflected in the broader population, in which dualistic intuitions abound. Drawing on recent empirical evidence, this essay presents a dual-process cognitive model of consciousness attribution. This dual-process model, we suggest, provides an important (...) part of the explanation for why dualism is so attractive and the explanatory gap so vexing. (shrink)

Disagreement as we find it in both the history and the contemporary practice of philosophy is an inadequately understood phenomenon. In this paper I outline and motivate the problem of disagreement, arguing that "hard cases" of disagreement confront us with an unresolved, and seemingly unresolvable, challenge to the rationality of philosophical discourse, thereby raising the specter of a worri-some form of metaphilosophical skepticism. A variety of responses and attempted evasions are considered, though none are found to be particularly satisfying: Thus, (...) the specter remains unexorcised. El desacuerdo que encontramos tanto en la historia como en la práctica contemporánea de la filosofía es un fenómeno mal entendido. En este trabajo hago un esbozo y aduzco los motivos del problema del desacuerdo, argumentando que los "casos difíciles" de desacuerdo nos confrontan con un problema sin resolver y al parecer sin posibilidad de resolverse, que pone en duda la racionalidad del discurso filosófico, y con lo cual surge el espectro de una preocupante forma de escepticismo metafilosófico. Examino varias respuestas y tentativas de evasiones, aunque ninguna de ellas es particularmente satisfactoria. Así, el espectro sigue sin ser exorcizado. (shrink)

According to both traditional positivist approaches and also to the sociology of scientific knowledge, social analysts should not themselves become involved in the controversies they are investigating. But the experiences of the authors in studying contemporary scientific controversies—specifically, over the Australian Animal Health Laboratory, fluoridation, and vitamin C and cancer—show that analysts, whatever their intentions, cannot avoid being drawn into the fray. The field of controversy studies needs to address the implications of this process for both theory and practice.

The notion that visual attention can operate over visual objects in addition to spatial locations has recently received much empirical support, but there has been relatively little empirical consideration of what can count as an `object' in the ®rst place. We have investi- gated this question in the context of the multiple object tracking paradigm, in which subjects must track a number of independently and unpredictably moving identical items in a ®eld of identical distractors. What types of feature clusters can (...) be tracked in this manner? In other words, what counts as an `object' in this task? We investigated this question with a technique we call target merging: we alter tracking displays so that distinct target and distractor loca- tions appear perceptually to be parts of the same object by merging pairs of items (one target with one distractor) in various ways ± for example, by connecting item locations with a simple line segment, by drawing the convex hull of the two items, and so forth. The data show that target merging makes the tracking task far more dif®cult to varying degrees depending on exactly how the items are merged. The effect is perceptually salient, involving in some conditions a total destruction of subjects' capacity to track multiple items. These studies provide strong evidence for the object-based nature of tracking, con®rming that in some contexts attention must be allocated to objects rather than arbitrary collections of features. In addition, the results begin to reveal the types of spatially organized scene components that can be independently attended as a function of properties such as connectedness, part struc- ture, and other types of perceptual grouping. q 2001 Elsevier Science B.V.

Since its publication in 1965 _Political Argument_ has come to be recognized as occupying a key position in the revival of Anglo-American political philosophy. A number of the ideas introduced by Barry have become part of the standard vocabulary, such as the distinction between ideal-regarding and want-regarding principles and the division of principles into aggregative and distributive. _Political Argument_ provided the first precise analysis, still frequently cited, of the conception that political values have trade-off relations; the analysis of the notion (...) of the public interest has also enjoyed wide influence. For this long-awaited reprint, the author has prepared a substantial, new introductory essay in which he recounts the process of writing the book and sets it in the intellectual milieu of its time. He then offers extensive comments on the subsequent fate of some of the leading ideas and assesses the book in light of criticisms and later developments. Finally, Barry evaluates current approaches to political philosophy as they look today. This new edition of _Political Argument_ will interest political theorists, philosophers, economists, and a range of other scholars. Brilliant and incisive, it will engender discussion and debate from many quarters. (shrink)
