This book examines why individuals and communities invest heavily in their religious life through multi-disciplinary perspectives. It pursues philosophical, psychological, deep time historical and adaptive answers to this question. Religion is a profoundly puzzling phenomenon from an evolutionary perspective. Commitment to religions are typically expensive, and most of the beliefs that motivate them cannot be true (since religious belief systems are inconsistent with one another). Yet some form of religion seems to be universal and resilient in historically known cultures – (...) though not, if archaeology is to be trusted, in human communities early in the evolution of our species. We have collectively invented religion over about the last 100,000 years. Stemming from an interdisciplinary workshop, this book grapples with these challenges and features diverse contributions: some offer evolutionary and historical analyses, identifying hidden adaptive benefits to religion independent of the veracity of religious belief. Others see connections between religious commitment and commitment to the social norms that make cooperative life possible and explore aspects of human psychology that make religious belief tempting. Broad in scope and theoretically ambitious, Religion and Its Evolution: Signals, Norms and Secret Histories will be a key resource for scholars and researchers of religious studies, sciences of religion, psychology, anthropology, the cultural evolution of religion and the sociology of religion. This book was originally published as a special issue of Religion, Brain & Behavior. (shrink)

The selected effects or ‘etiological’ theory of Proper function is a naturalistic and realist account of biological teleology. It is used to analyse normativity in philosophy of language, philosophy of mind, philosophy of medicine and elsewhere. The theory has been developed with a simple and intuitive view of natural selection. Traits are selected because of their positive effects on the fitness of the organisms that have them. These ‘selected effects’ are the Proper functions of the traits. Proponents argue that this (...) analysis of biological teleology has the unique advantage that the selected effect function of a trait is also a causal explanation of the trait: the trait exists because it performs this function. We show, however, that selected effect functions as currently defined explain the existence of traits only under highly restrictive assumptions about evolutionary dynamics. In many common scenarios in which traits evolve by natural selection, selected effect functions do not explain those traits. This is because definitions of selected effect function extract from any evolutionary scenario only the information that would be explanatorily relevant in the simple evolutionary scenario implicit in those definitions. When applied to more complex scenarios selected effect functions omit the key information that is explanatorily relevant in those scenarios. The assumptions required for selected effect functions to be explanatory are particularly unlikely to hold in the domain that its proponents care most about - the evolution of representation. A more adequate selected effects theory of Proper functions may be possible, but will require much greater attention to the structure of actual evolutionary explanations. (shrink)

We consider modifications to the standard David Lewis signaling game and relax a number of unrealistic implicit assumptions that are often built into the framework. In particular, we motivate and explore various asymmetries that exist between the sender and receiver roles. We find that endowing receivers with a more realistic set of responses significantly decreases the likelihood of signaling, while allowing for unequal selection pressure often has the opposite effect. We argue that the results of this article can also help (...) make sense of a well-known evolutionary puzzle regarding the absence of an evolutionary arms race between sender and receiver in conflict-of-interest signaling games.

Conceptual change can occur for a variety of reasons; some more scientifically significant than others. The 2006 definition of ‘planet’, which saw Pluto reclassified as a dwarf planet, is an example toward the more mundane end of the scale. I argue however that this case serves as a useful example of a related phenomenon, whereby what appears to be a single kind term conceals two or more distinct concepts with independent scientific utility. I examine the historical background to this case, (...) as a template for developing additional evidence for pluralist approaches to conceptual disputes within science and elsewhere. (shrink)

The signaling theory of religion has many claimed virtues, but these are not necessarily all realizable at the same time. Modeling choices involve trade-offs, and the available options here have not traditionally been well understood. This paper offers an overview of signaling theory relevant to the signaling theory of religion, arguing for a narrow, “core” reading of it. I outline a broad taxonomy of the choices on offer for signaling models, and examples of how previous and potential approaches to modeling (...) religious signaling meet or fail to meet the initial promise of the theory. A pluralist approach to religious signaling seems possible, but this would require a high level of detail and specificity with respect to both formal models and target systems. (shrink)

The origins of human social cooperation confound simple evolutionary explanation. But from Darwin and Durkheim onward, theorists (anthropologists and sociologists especially) have posited a potential link with another curious and distinctively human social trait that cries out for explanation: religion. This dissertation explores one contemporary theory of the co-evolution of religion and human social cooperation: the signalling theory of religion, or religious signalling theory (RST). According to the signalling theory, participation in social religion (and its associated rituals and sanctions) acts (...) as an honest signal of one’s commitment to a religiously demarcated community and its way of doing things. This signal would allow prosocial individuals to positively assort with one another for mutual advantage, to the exclusion of more exploitative individuals. In effect, the theory offers a way that religion and cooperation might explain one another, but which that stays within an individualist adaptive paradigm. My approach is not to assess the empirical adequacy of the religious signalling explanation or contrast it with other explanations, but rather to deal with the theory in its own terms – isolating and fleshing out its core commitments, explanatory potential, and limitations. The key to this is acknowledging the internal complexities of signalling theory, with respect to the available models of honest signalling and the extent of their fit (or otherwise) with religion as a target system. The method is to take seriously the findings of formal modelling in animal signalling and other disciplines, and to apply these (and methods from the philosophy of biology more generally) to progressively build up a comprehensive picture of the theory, its inherent strengths and weaknesses. The first two chapters outline the dual explanatory problems that cooperation and religion present for evolutionary human science, and surveys contemporary approaches toward explaining them. Chapter three articulates an evolutionary conception of the signalling theory, and chapters four to six make the case for a series of requirements, limitations, and principles of application. Chapters seven and eight argue for the value of formal modelling to further flesh out the theory’s commitments and potential and describe some simple simulation results which make progress in this regard. Though the inquiry often problematizes the signalling theory, it also shows that it should not be dismissed outright, and that it makes predictions which are apt for empirical testing. (shrink)

We argue that Stanford’s picture of the evolution of externalised norms is plausible mostly because of the idealisations implicit in his defence of it. Once we take into account plausible amounts of normative disagreement, plausible amounts of error and misunderstanding, and the knock-on consequences of shunning, it is plausible that Stanford under-counts the costs of externalisation.

This paper examines and contrasts two closely related evolutionary explanations in human behaviour: signalling theory, and the theory of Credibility Enhancing Displays. Both have been proposed to explain costly, dangerous, or otherwise ‘extravagant’ social behaviours, especially in the context of religious belief and practice, and each have spawned significant lines of empirical research. However, the relationship between these two theoretical frameworks is unclear, and research which engages both of them is largely absent. In this paper we seek to address this (...) gap at the theoretical level, examining the core differences between the two approaches and prospects and conditions for future empirical testing. We clarify the dynamical and mechanistic bases of signalling and CREDs as explanatory models and contrast the previous uses to which they have been put in the human sciences. Because of idiosyncrasies regarding those uses, several commonly supposed differences and comparative advantages are actually misleading and not in fact generalisable. We also show that signalling and CREDs theories as explanatory models are not interchangeable, because of deep structural differences. As we illustrate, the proposed causal networks of each theory are distinct, with important differences in the endogeneity of various phenomena within each model and their explanatory targets. As a result, they can be seen as complementary rather than in competition. We conclude by surveying the current state of the literature and identifying the differential predictions which could underpin more comprehensive empirical comparison in future research. (shrink)

It is often taken for granted that notions of health and disease are generally applicable across the biological world, in that they are not restricted to contemporary human beings, and can be unproblematically applied to a variety of organisms both past and present (taking relevant differences between species into account). In the historical sciences it is also common to normatively contrast health states of individuals and populations from different times and places: e.g., to say that due to nutrition or pathogen (...) load, some lived healthier lives than others. However, health concepts in contemporary philosophy of medicine have not been developed with such cross-lineage, non-human, or diachronic uses in mind, and this generates what I call the ‘new normal’ problem. I argue that the new normal problem shows that current naturalistic approaches to health (when based on biological reference classes) are worryingly incomplete. Using examples drawn from evolutionary archaeology and the human fossil record, I outline an alternative, function-based strategy for naturalizing health that might help address the new normal problem. Interestingly, this might also reconstruct a certain uniqueness for humans in the philosophy and science of health, due to the deep history of obligate enculturation and cultural adaptation that archaeology demonstrates.

Mehr et al. seek to explain music's evolution in terms of a unitary proper function – signalling cooperative intent – which they cash out in two guises, coalition signalling and parental attention signalling. Although we recognize the role signalling almost certainly played in the evolution of music, we reject “ultimate” causal explanations which focus on a unidirectional, narrow range of causal factors.

Veissière et al. must sacrifice explanatory realism and precision in order to develop a unified formal model. Drawing on examples from cognitive archeology, we argue that this makes it difficult for them to derive the kinds of testable predictions that would allow them to resolve debates over the nature of human social cognition and cultural acquisition.

The handicap principle stipulates that signal reliability can be maintained if signals are costly to produce. Yet empirical biologists are typically unable to directly measure evolutionary costs, and instead appeal to expenditure as a sensible proxy. However the link between expenditure and cost is not always as straightforward as proponents of HP assume. We consider signaling interactions where whether the expenditure associated with signaling is converted into an evolutionary cost is in some sense dependent on the behavior of the intended (...) recipient of the signal. We illustrate this with a few empirical examples and demonstrate that on this alternative expenditure to cost mapping the traditional predictions of HP no longer hold. Instead of full information transfer, a partially informative communication system like those uncovered by Wagner :163–181, 2013) and Zollman et al. is possible. (shrink)

Cultural evolution is a growing, interdisciplinary, and disparate field of research. In ‘Cultural evolution: conceptual challenges”, Tim Lewens offers an ambitious analytical survey of this field that aims to clarify and defend its epistemic contributions, and highlight the limitations and risks associated with them. One overarching contention is that a form of population thinking dubbed the ‘kinetic approach’ should be seen as a unifying and justifying principle for cultural evolution, especially when considering the role of formal modelling. This book makes (...) a number of extremely valuable contributions to the literature. However, I argue that not all is as it may seem regarding the kinetic approach and that, while it does little to diminish the book’s value, the use which Lewens makes for it is problematic. (shrink)

With this volume, the author stakes out a bold, authoritative position in the multidisciplinary literature on cultural evolution and human uniqueness.

This book takes a brain-centric approach to the evolution of religion, where the evolution of religion is the evolution of cognitive capacities and the evolution of these is rooted in that of the brain.

With In Search of Mechanisms, Carl F. Craver and Lindley Darden offer both a descriptive and an instructional account of how biologists discover mechanisms. Drawing on examples from across the life sciences and through the centuries, Craver and Darden compile an impressive toolbox of strategies that biologists have used and will use again to reveal the mechanisms that produce, underlie, or maintain the phenomena characteristic of living things. They discuss the questions that figure in the search for mechanisms, characterizing (...) the experimental, observational, and conceptual considerations used to answer them, all the while providing examples from the history of biology to highlight the kinds of evidence and reasoning strategies employed to assess mechanisms. At a deeper level, Craver and Darden pose a systematic view of what biology is, of how biology makes progress, of how biological discoveries are and might be made, and of why knowledge of biological mechanisms is important for the future of the human species.

Under what conditions are people responsible for their choices and the outcomes of those choices? How could such conditions be fostered by liberal societies? Should what people are due as a matter of justice depend on what they are responsible for? For example, how far should healthcare provision depend on patients' past choices? What values would be realized and which hampered by making justice sensitive to responsibility? Would it give people what they deserve? Would it advance or hinder equality? The (...) explosion of philosophical interest in such questions has been fuelled by increased focus on individual responsibility in political debates. Political philosophers, especially egalitarians, have responded to such developments by attempting to map out the proper place for responsibility in theories of justice. This book both reflects on these recent developments in normative political theory and moves the debate forwards. (shrink)

In his historical perspective on the changes in scientific thought over the last 100 years, Carl N. Degler explores the study of social evolution and the ongoing search for human nature. In Search of Human Nature provides a detailed perspective on the reasons behind the shifting emphasis in social thought from biology, to culture, and again to biology. Degler examines why these changes took place, the evidence and people fostering these changes and why students of human nature decided to (...) accept this momentous change in thought. He suggests varying ideologies as the underlying force behind this shift in the study of social science. From Darwin's theory that human social behaviour has drastically evolved from animals, to the belief that human experience serves as the basic differentiating factor in humans, Degler provides a thorough and captivating examination of the roots of human behaviour.

Much more than their machinic reality, current iterations of AI rely on imagined divisions of human and non-human properties and skills that have genealogical ties to colonization. For this reason, research efforts have recently been made to historicize these imaginaries, connecting them to colonial ideals that delegate black and brown colonized people into the realm of the non-human. Atanasoski and Vora (Surrogate humanity. Race, robots and the politics of technological futures, Duke, Durham and London, 2019) have called this a “surrogate (...) humanity”, where narratives of autonomous technologies function to disappear precisely the formerly colonized peoples that are enveloped in its production process. At the same time, the gendered and racialized roots of this maternal figure represents an opportunity to uncover and critique the invisibilization of embodied resources necessary to produce AI, precarious bodies labouring to produce algorithmic infrastructures in a manner that can be considered in a genealogy of carework and reproduction. These genealogies complicate the detachment suggested by the surrogate figure and go beyond it to proclaim a more generative function of the relationship between the black maternal figure and AI. The article analyses Tabita Rezaire’s multi-media artwork Sugar Walls Teardom to think through decolonial and queer renderings of the black female bodies upon which technological imaginaries rest, to extend beyond AI surrogacy and towards notions of kinship, care and world-making by producing an AI aesthetics that is relational, embodied, and celebratory of other ways of liveness.

Community-based participatory research (CBPR) focuses on specific community needs, and produces results that directly address those needs. Although conducting ethical CBPR is critical to its success, few academic programs include this training in their curricula. This article describes the development and evaluation of an online training course designed to increase the use of CBPR in mental health disciplines. Developed using a participatory approach involving a community of experts, this course challenges traditional research by introducing a collaborative process meant to encourage (...) increased participation by special populations and narrow the parity gap in effective mental health treatment and services delivery.

Carl Schmitt and the Problem of the Realization of Law 1. The famous pithy aphorisms that Carl Schmitt used to open his major works - 'the sovereign is he who decides on the exception', 'the concept of the state presupposes the concept of the political', etc. - have become a part of the common discourse of contemporary scholarship on politics and the law. The theoretical framework that animates these slogans, however, has remained somewhat opaque. It has often been (...) argued that there is no such framework, that Schmitt was a situational thinker whose works are best understood as interventions in concrete political debates that do not add up to a grand theoretical vision.

This article argues that, suitably modified, the method of reflective equilibrium is a plausible way of selecting moral principles. The appropriate conception of the method is wide and radical, admitting consideration of a full range of moral principles and arguments, and requiring the enquiring individual to consider others' views and undergo experiences that may offset any formative biases. The individual is not bound by his initial considered judgments, and may revise his view in any way whatsoever. It is appropriate to (...) describe the method as a balance between coherentism and fallibilist foundationalism. With these points in mind, various criticisms, including the claims that considered judgments are not initially credible and are shaped by prejudice, and that the method itself fails to determine principle selection, are challenged.

Carl Craver investigates what we are doing when we sue neuroscience to explain what's going on in the brain.

The world is awash in bullshit, and we're drowning in it. Politicians are unconstrained by facts. Science is conducted by press release. Startup culture elevates bullshit to high art. These days, calling bullshit is a noble act. Based on Carl Bergstrom and Jevin West's popular course at the University of Washington, Calling Bullshit is a modern handbook to the art of skepticism. Bergstrom, a computational biologist, and West, an information scientist, catalogue bullshit in its many forms, explaining and offering (...) readers the tools to see through the obfuscations, deliberate and careless, that dominate every realm of our lives. They instruct readers to ask: Who is saying it? How do they know? What do they have to gain by persuading me? Are the numbers or results too good or too dramatic to be true? Is the claim comparing like with like or apples and oranges? Is it confirming your personal bias? In this lively guide to everything from misleading statistics to "fake news," Bergstrom and West help you recognize bullshit whenever and wherever you encounter it--in data, in conversation, even within yourself--and explain it to your crystal-loving aunt or casually racist uncle. Now more than ever, calling bullshit is crucial to a properly functioning community, whether it be a circle of friends, a network of academics, or the citizenry of a nation. (shrink)

Racial preferences are among the most contentious issues in our society, touching on fundamental questions of fairness and the proper role of racial categories in government action. Now two contemporary philosophers, in a lively debate, lay out the arguments on each side. Carl Cohen, a key figure in the University of Michigan Supreme Court cases, argues that racial preferences are morally wrong--forbidden by the 14th Amendment to the Constitution, and explicitly banned by the Civil Rights Act of 1964. He (...) also contends that such preferences harm society in general, damage the universities that use them, and undermine the minorities they were intended to serve. James P. Sterba counters that, far from being banned by the Constitution and the civil rights acts, affirmative action is actually mandated by law in the pursuit of a society that is racially and sexually just. The same Congress that adopted the 14th Amendment, he notes, passed race-specific laws that extended aid to blacks. Indeed, there are various kinds of affirmative action--compensation for past discrimination, remedial measures aimed at current discrimination, the guarantee of diversity--and Sterba reviews the Supreme Court cases that build a constitutional foundation for each. Affirmative action, he argues, favors qualified minority candidates, not unqualified ones. Both authors offer concluding comment on the University of Michigan cases decided in 2003. Half a century after Brown v. Board of Education, issues pertaining to racial discrimination continue to grip American society. Ideal for courses in political, social, ethical, and legal philosophy, this penetrating debate explores the philosophical and legal arguments on all sides of affirmative action, but also reveals the passions that drive the issue to the forefront of public life.

One of the most prominent African American intellectuals of the twentieth century, W. E. B. Du Bois continues to influence the understanding of race relations in the United States. In this deeply personal introduction to the man and his ideas, esteemed scholar Carl A. Grant reflects on how Du Bois's work has illuminated his own life practices as a Black student, teacher, assistant principal, and professor. Sharing the story of a brilliant man's life contribution to teaching about race and (...) the ideologies and methodologies of racism in education and social and political thought, Grant begins his narrative with a broad overview of Du Bois's life and scholarship, before turning more specifically to Du Bois's theory of an educational system. The book concludes with an examination of Du Bois's curriculum model, predicated upon the work of the NAACP, the Harlem Renaissance, and Du Bois's own writings, as well as a discussion of the lasting legacy of Du Bois's educational and social theory in the present day. Ideal for graduate-level courses in curriculum theory, educational foundations, and education history, Du Bois and Education provides an in-depth examination of Du Bois's scholarship, social criticism, and political thought as they relate to his educational theory.
