Henrich et al.'s findings are generally consistent with the findings of other experimental field studies. However, the methodological variations deployed across field sites produced several systematic biases in their results. Hence, although the project is destined to become a watershed study, their results should be interpreted prudently.

We argue that ritual is not a by-product as Boyer & Lienard (B&L) claim, but rather an evolved adaptation for social communication that facilitates non-agonistic social interactions among non-kin. We review the neurophysiological effects of ritual and propose neural structures and networks beyond the cortical-striato-pallidal-thalamic circuit (CSPT) likely to be implicated in ritual. The adaptationist approach to ritual offers a more parsimonious model for understanding these effects as well as the findings B&L present. (Published Online February 8 2007).

In this paper I explore the psychology of ritual performance and present a simple graphical model that clarifies several issues in William Irons’s theory of religion as a “hard-to-fake” sign of commitment. Irons posits that religious behaviors or rituals serve as costly signals of an individual’s commitment to a religious group. Increased commitment among members of a religious group may facilitate intra-group cooperation, which is argued to be the primary adaptive benefit of religion. Here I propose a proximate explanation for (...) how individuals are able to pay the short-term costs of ritual performance to achieve the long-term fitness benefits offered by religious groups. The model addresses three significant problems raised by Irons’s theory. First, the model explains why potential free-riders do not join religious groups even when there are significant net benefits that members of religious groups can achieve. Second, the model clarifies how costly a ritual must be to achieve stability and prevent potential free-riders from joining the religious group. Third, the model suggests why religious groups may require adherents to perform private rituals that are not observed by others. Several hypotheses generated from the model are also discussed.

This paper considers religion in relation to four recurrent traits: belief systems incorporating supernatural agents and counterintuitive concepts, communal ritual, separation of the sacred and the profane, and adolescence as a preferred developmental period for religious transmission. These co-occurring traits are viewed as an adaptive complex that offers clues to the evolution of religion from its nonhuman ritual roots. We consider the critical element differentiating religious from non-human ritual to be the conditioned association of emotion and abstract symbols. We propose (...) neurophysiological mechanisms underlying such associations and argue that the brain plasticity of human adolescence constitutes an “experience expectant” developmental period for ritual conditioning of sacred symbols. We suggest that such symbols evolved to solve an ecological problem by extending communication and coordination of social relations across time and space. (shrink)

In this paper we examine the merit of bargaining theory, in its economic and ecological forms, as a model for understanding variation in the frequency of participation in cooperative fishing among men of Ifaluk atoll in Micronesia. Two determinants of bargaining power are considered: resource control and a bargainer’s utility gain for his expected share of the negotiated resource. Several hypotheses which relte cultural and life-course parameters to bargaining power are tested against data on the frequency of cooperative sail-fishing participation. (...) Consistent with predictions generated from bargaining theory, we show that (1) age is negatively correlated with cooperative fishing participation, (2) men of highranking clans and men with high levels of education fish less than men of low-ranking clans and less-educated men, (3) men with high expected utility gains from fishing returns fish more than men with low expected utility gains, (4) number of dependents is positively correlated with cooperative fishing participation, and (5) the number of young genetic offspring residing with a man is positively correlated with cooperative fishing participation, whereas the number of genetic offspring more than 13 years old who are residing with a man is negatively correlated with cooperative fishing participation.

We argue that religious ritual's ability to facilitate communication and the pervasiveness of its basic characteristics across societies, as well as its precedence in other social species, suggests that religious behavior is more than a mere by-product. Religious constructs constitute associationally conditioned mnemonics that trigger neuroendocrine responses which motivate religious behaviors. The adaptive value of these constructs resides in their utility as memorable and emotionally evocative primes.

There has been increasing interest in the evolutionary study of religion, but perfunctory fractionalization has limited our ability to explain how and why religion evolved, evaluate religion’s current adaptive value, and assess its role in contemporary decision-making. To move beyond piecemeal analyses of religion, I have recently offered an integrative evolutionary framework that approaches religions as adaptive systems. I argue that religions are an adaptive complex of traits consisting of cognitive, neurological, affective, behavioral, and developmental features that are organized into (...) a self-regulating feedback system. Here I explore four advantages of this systemic approach to religion: it avoids definitional problems that have plagued the study of religion, affords a contextual understanding of religious belief, informs current debates within the evolutionary study of religion, and provides links to both the natural sciences and humanities. I argue that the systemic approach offers the strongest potential for real progress and broad application of evolutionary theory to the study of religion. (shrink)

The fish-sharing patterns on Ifaluk Atoll underscore several limitations of the explanations of food sharing offered by Gurven and suggest that non-foraging labor activities may provide insights into reciprocity and punishment relevant for understanding food-sharing patterns. I also argue that future food-sharing studies should focus on signaling rather than resource holding potential (RHP).

Anthropological tests of patch choice models from optimal foraging theory have primarily employed acquisition rates as the currency of the model. Where foragers share their returns, acquisition rates may not be similar to consumption rates and thus may not be an appropriate currency to use when modeling foraging decisions. Indeed, on Ifaluk Atoll the distribution patterns of fish vary by fishing method and location. Previous analyses of Ifaluk patch choice decisions suggested that if Ifaluk fishers are trying to maximize their (...) production rates they should rarely torch fish for dogtoothed tuna. However, some men do spend considerable time and energy exploiting the dogtoothed tuna patch. To improve our understanding of the constraints and motivations influencing men’s decisions to exploit this patch, here I use per capita consumption rates as a currency, rather than production rates, to evaluate predictions generated from a patch choice model. Results indicate that although fish caught in other patches are more widely distributed than fish caught in the dogtoothed tuna patch, the consumption rates of torch fishers and their kin are still considerably lower than the consumption rates of men pursuing fish in other patches. Although these results are unable to explain why Ifaluk men exploit the dogtoothed tuna patch, an important explanatory hypothesis is eliminated. (shrink)

Life history theory aims to explain the relationship between life events, recognizing that the fertility and growth schedules of organisms are dependent on environmental conditions and an organism’s ability to extract resources from its environment. Using models from life history theory, we predict life expectancy to be positively correlated with educational investments and negatively correlated with adolescent reproduction and total fertility rates. Analyses of UN data from 193 countries support these predictions and demonstrate that, although variation is evident across world (...) regions, strong interactions exist among life expectancy, reproductive investments, and educational attainment, and these relationships occur independently of economic pressures and disease burdens. The interactions are strongest, however, in countries with a life expectancy of ≥60 years as these countries tend to have stable economies and a limited HIV/AIDS burden. These findings suggest that policies aimed at influencing education and reproductive decisions should consider environmental characteristics that drive people’s expectations about their longevity.

McKay & Dennett (M&D) observe that beliefs need not be true in order to evolve. We connect this insight with Schelling's work on cooperative commitment to suggest that some beliefs are best approached as social goals. We explain why a social-interactive perspective is important to explaining the dynamics of belief formation and revision among situated partners.

We argue that a closer look at the practices and tools that humans use to support willpower, and the cultural contexts in which they are employed, can broaden the applicability of Ainslie's theory and facilitate the development of more effective self-control techniques. To support our argument, we examine Alcoholics Anonymous's method of temptation resistance known as “playing the tape through”.

Juslin & Vll (J&V) advance our understanding of the proximate mechanisms underlying emotional responses to music, but fail to integrate their findings into a comprehensive evolutionary model that addresses the adaptive functions of these responses. Here we offer such a model by examining the ontogenetic relationship between music, ritual, and symbolic abstraction and their role in facilitating social coordination and cooperation.

We argue that limiting the theory of extreme self-sacrifice to two determinants, namely, identity fusion and group threats, results in logical and conceptual difficulties. To strengthen Whitehouse's theory, we encourage a more holistic approach. In particular, we suggest that the theory include exogenous sociopolitical factors and constituents of the religious system as additional predictors of extreme self-sacrifice.

Current evolutionary and cognitive theories of religion posit that supernatural agent concepts emerge from cognitive systems such as theory of mind and social cognition. Some argue that these concepts evolved to maintain social order by minimizing antisocial behavior. If these theories are correct, then people should process information about supernatural agents’ socially strategic knowledge more quickly than non-strategic knowledge. Furthermore, agents’ knowledge of immoral and uncooperative social behaviors should be especially accessible to people. To examine these hypotheses, we measured response-times (...) to questions about the knowledge attributed to four different agents—God, Santa Claus, a fictional surveillance government, and omniscient but non-interfering aliens—that vary in their omniscience, moral concern, ability to punish, and how supernatural they are. As anticipated, participants respond more quickly to questions about agents’ socially strategic knowledge than non-strategic knowledge, but only when agents are able to punish. (shrink)

The evolution of religious traditions may be partially explained by out-group avoidance due to pathogen stress. However, many religious rituals may increase rather than decrease performers' susceptibility to infection. Moreover, religions often spread through proselytizing, which requires out-group interaction; and in other cases, the benefits of economic exchange increase religious pluralism and social interactions with out-groups.

From the Introduction: This inquiry is concerned with the themes of praxis and action in four philosophic movements: Marxism, existentialism, pragmatism, and analytic philosophy. It is rare that these four movements are considered in a single inquiry, for there are profound differences of emphasis, focus, terminology, and approach represented by these styles of thought. Many philosophers believe that similarities among these movements are superficial and that a close examination of them will reveal only hopelessly unbridgeable cleavages. While respecting the genuine (...) fundamental differences of these movements, this inquiry is undertaken in the spirit of showing that there are important common themes and motifs in what first appears to be a chaotic babble of voices. I intend to show that the concern with man as an agent has been a primary focal point of each of these movements and further that each contributes something permanent and important to our understanding of the nature and context of human activity.

This book offers students a philosophical introduction to the ethical foundations of business management. It combines lessons from Kant with virtue ethics and also touches upon additional approaches such as utilitarianism. At the core of the book lies the concept of the nexus of imperfect managerial duty: building and reinforcing the virtuous managerial team, engaging in reasoned discourse among all stakeholders, and diligently pursuing business responsibilities, including the creative efforts necessary for modern organizations. Case illustrations of these applications are presented (...) throughout the book, including chapter appendices. Ancillary videos, test and answer banks and sample syllabi are available online via the author’s website. (shrink)

Drawing freely and expertly from Continental and analytic traditions, Richard Bernstein examines a number of debates and controversies exemplified in the works of Gadamer, Habermas, Rorty, and Arendt. He argues that a "new conversation" is emerging about human rationality—a new understanding that emphasizes its practical character and has important ramifications both for thought and action.

In this paper I argue that resource allocation in publicly funded medical systems cannot be done using a purely substantive theory of justice, but must also involve procedural justice. I argue further that procedural justice requires institutions and that these must be “local” in a specific sense which I define. The argument rests on the informational constraints on any non-market method for allocating scarce resources among competing claims of need. However, I resist the identification of this normative account of local (...) justice with the actual approach to local decision-making taken within the UK National Health Service. I illustrate my argument with reference to the case of provision of In Vitro Fertilisation within the UK NHS. (shrink)

To Serve With Honor should be required reading for all members of the officer corps of the United States military. Beyond that, it should be made required reading for all United States military academies, ROTC and officer candidate programs. This treatise on military ethics goes a long way in bridging the gap between the military and society's understanding of the military's ethical dilemma. It is a must for the student of military affairs. International Social Science Review To Serve With Honor (...) is the first book by an American to focus on the validity of current standards of military ethics in more than a century. This thoughtful study begins with the premise that the military profession is qualitatively different from any other profession. Author Richard Gabriel uses this assumption to address such vital questions as What are the limits of military obedience? and When does a soldier have an obligation to resist the orders of his superiors?

Few philosophers have been as widely misunderstood as Nietzsche. His detractors and followers alike have often fundamentally misinterpreted him, distorting his views and intentions and criticizing or celebrating him for reasons removed from the views he actually held. Now available in paper, Nietzsche assesses his place in European thought, concentrating upon his writings in the last decade of his productive life. Nietzsche emerges in this comprehensive study as a philosopher of considerable sophistication who diverged sharply from traditional and ordinary ways (...) of thinking, but whose criticism, departures, and alternative views and strategies deserve to be given the most serious attention by philosophers.

This article outlines how the international push for inclusive education cannot be aligned with current education systems centred on neoliberal ideals of individualism, measurement, and competition. The way that these systems are organised means that a proportion of (usually marginalised) students are necessarily excluded. In order to meaningfully address the global education crisis, that sees millions of children and young people either out of school or unengaged with learning, this ontological misalignment must be acknowledged, and discourse and engagement around it (...) must be promoted. Drawing from the work of Donella Meadows, I argue that ‘high leverage points’ (information flows, rules, system goals, mindsets) are crucial places to intervene in education systems. Intervention at such points, while challenging, has the potential to lead to transformational and sustainable change; change that current ‘low leverage point’ initiatives fail to produce. I conclude with a call for further discourse and research into an examination of ‘high leverage points’ within education systems, how they interact, and how the development of an associated framework would be beneficial for researchers and development partners.

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Orientalism and Religion offers us a timely discussion of the implications of contemporary post-colonial theory for the study of religion. Drawing on a variety of post-structuralist and post-colonial thinkers, including Foucault, Gadamer, Said, and Spivak, Richard King examines the way in which notions such as mysticism, religion, Hinduism and Buddhism are taken for granted, and shows us how religion needs to be redescribed along the lines of cultural studies.

The discussion of good and evil must not be confined to the sterile lecture halls of academics but related instead to ordinary human feelings, needs, and desires, says noted philosopher Richard Taylor. Efforts to understand morality by exploring human reason will always fail because we are creatures of desire as well. All morality arises from our intense and inescapable longing. The distinction between good and evil is always clouded by rationalists who convert the real problems of ethics into complex (...) philosophical puzzles. In the first part of Good and Evil, Taylor looks for a more meaningful conception by reexamining and rejecting the whole rationalistic tradition that dominates philosophical ethics. The second part provides an empirical explanation of good and evil, noting that one does not have to look too far to find prime examples of the failure of fixed moral rules. Including important commentary on Joseph Fletcher's groundbreaking situation ethics, and Aristotle's virtues (e.g., magnanimity and pride), Taylor rounds out the book by developing a philosophy of aspiration--personal worth as an ethical ideal--to replace the morality of duty. He offers a modified form of situation ethics to fit the contemporary problems we face. (shrink)

Ducklings were placed either singly or in pairs on a platform at two different heights. Both height and pairing influenced performance: More ducklings descended from the platform at low heights, and more single ducklings descended than paired ducklings. The social factor, pairing, made behavior more cautious and decreased the number of distress calls. A similar trend for pairing to influence performance was shown on the visual cliff. Without its peers, the duckling is a distressed animal. Previous careless behavior by ducklings (...) on the visual cliff may be ascribed to testing the ducklings outside their normal social environment. (shrink)
