If culture is defined as variation acquired and maintained by social learning, then culture is common in nature. However, cumulative cultural evolution resulting in behaviors that no individual could invent on their own is limited to humans, song birds, and perhaps chimpanzees. Circumstantial evidence suggests that cumulative cultural evolution requires the capacity for observational learning. Here, we analyze two models the evolution of psychological capacities that allow cumulative cultural evolution. Both models suggest that the conditions which allow the evolution of (...) such capacities when rare are much more stringent than the conditions which allow the maintenance of the capacities when common. This result follows from the fact that the assumed benefit of the capacities, cumulative cultural adaptation, cannot occur when the capacities are rare. These results suggest why such capacities may be rare in nature. (shrink)

E.O. Wilson (1975) described humans as one of the four pinnacles of social evolution. The other pinnacles are the colonial invertebrates, the social insects, and the non-human mammals. Wilson separated human sociality from that of the rest of the mammals because, with the exception of the social insect like Naked Mole Rats, only humans have generated societies of a grade of complexity that approaches that of the social insects and colonial invertebrates. In the last few millennia, human societies have even (...) begun to exceed, in numbers of individuals and degree of complexity, the societies of ants, termites, and corals. (shrink)

Among the many vivid metaphors in Darwin’s Dangerous Idea, one stands out. The understanding of how cumulative natural selection gives rise to adaptations is, Dennett says, like a “universal acid”—an idea so powerful and corrosive of conventional wisdom that it dissolves all attempts to contain it within biology. Like most good ideas, this one is very simple: Once replicators (material objects that are faithfully copied) come to exist, some will replicate more rapidly than others, leading to adaptation by natural selection. (...) The great power of the idea is that the resulting adaptations can be understood by asking what leads to efficient, rapid replication. Given that ideas seem to replicate, it is natural that Dawkins (1976, 1982), Dennett (1992), and others have explored the possibility of using this idea to explain cultural evolution. (shrink)

We review the evolutionary theory relevant to the question of human cooperation and compare the results to other theoretical perspectives. Then, we summarize some of our work distilling a compound explanation that we believe gives a plausible account of human cooperation and selfishness. This account leans heavily on group selection on cultural variation but also includes lower-level forces driven by both microscale cooperation and purely selfish motives. We propose that innate aspects of human social psychology coevolved with group-selected cultural institutions (...) to produce just the kinds of social and moral faculties originally proposed by Darwin. We call this the “tribal social instincts” hypothesis. The account is systemic in the sense that human social systems are functionally differentiated, conflicted, and diverse. A successful explanation of human cooperation has to account for these complexities. For example, a tribal-scale cultural group selection process alone cannot account for human patterns of cooperation because, on one hand, much conflict exists within tribes and, on the other, people have proven able to organize cooperation on a much larger scale than tribes. We include multilevel selection and gene–culture coevolution effects to account for some of these complexities and discuss empirical tests of the resulting hypotheses. In particular, we argue that strong support for the tribal social instincts hypothesis comes from the structure of modern social institutions. These institutions have conspicuous “work-arounds” that shed light on the underlying instincts. (shrink)

Is society an organic whole with each of its many components working together like the organs in a body? Like organisms, societies are composed of many parts which seem to work together enhance their survival. Different people fulfill different, necessary role—subsistence, reproduction, coordination, and defense. Regular exchange of matter and energy guarantees that each component has the resources it needs. Norms, laws and customs regulate virtually every aspect of social interaction, who may marry who, how disputes are resolved, and how (...) verbs should be conjugated. Ritual and religion provide comfort to the sick and fearful, maintain a feeling of solidarity and belonging, and serve to preserve and transmit knowledge through time. Even the simplest human societies seem like complex machines designed for growth and survival. (shrink)

The iterated prisoner’s dilemma (IPD) has been widely used in the biological and social sciences to model dyadic cooperation. While most of this work has focused on the discrete prisoner’s dilemma, in which actors choose between cooperation and defection, there has been some analysis of the continuous IPD, in which actors can choose any level of cooperation from zero to one. Here, we analyse a model of the continuous IPD with a limited strategy set, and show that a generous strategy (...) achieves the maximum possible payoff against its own type. While this strategy is stable in a neighborhood of the equilibrium point, the equilibrium point itself is always vulnerable to invasion by uncooperative strategies, and hence subject to eventual destabilization. The presence of noise or errors has no effect on this result. Instead, generosity is favored because of its role in increasing contributions to the most efficient level, rather than in counteracting the corrosiveness of noise. Computer simulation using a single-locus infinite alleles Gaussian mutation model suggest that outcomes ranging from a stable cooperative polymorphism to complete collapse of cooperation are possible depending on the magnitude of the mutational variance. Also, making the cost of helping a convex function of the amount of help provided makes it more difficult for cooperative strategies to invade a non-cooperative equilibrium, and for the cooperative equilibrium to resist destabilization by noncooperative strategies.

Most evolutionary analyses of animal communication suggest that low-cost signals can evolve only when both the signaller and the recipient rank outcomes in the same order. When there is a conflict of interest between sender and receiver, honest signals must be costly. However, recent work suggests that low-cost signals can be evolutionarily stable, even when the sender and the receiver rank outcomes in different orders, as long as the interest in achieving coordination is sufficiently great. In this paper, we extend (...) this body of work by analysing a game theory model that shows that low-cost signals can evolve when there are conflicts of interest and no interest in coordination, as long as individuals interact repeatedly. We also present an empirical example indicating that female rhesus macaques, Macaca mulatta, use honest, low-cost, vocal signals to facilitate interactions when conflicts of interest exist. (shrink)

Our aim in this chapter is to draw lessons from current theory on the evolution of human cooperation for the management of contemporary commons. Evolutionary theorists have long been interested in cooperation but social scientists have documented patterns of cooperation in humans that present unusual problems for conventional evolutionary theory (and for rational choice explanations as well). Humans often cooperate with nonrelatives and are prone to cooperate in one-shot games. Cooperation is quite dependent on social institutions. We believe that this (...) last fact is the critical clue to understanding human cooperation. Models of cultural evolution suggest that group selection is a more potent force on culture than on genes. Evolutionary theory is in essence a theory of preferences in terms of rational actor theory and is thus complementary to the bounded rational choice models that underpin so much theorizing in the social sciences. Thus, the theory suggests a source for prosocial impulses, and leads to predictions about the limits of human altruism and constraints likely to be imposed upon the evolution of social institutions. We also consider the dynamics of genes as they coevolved with increasingly sophisticated cultural institutions over the long course of human evolution in the Pleistocene. We hypothesize that the long exposure of human populations to group selected cultural norms and preferences is likely to have resulted in an innate psychology adapted to living in egalitarian, cooperative societies of a few hundred to a few thousand people. We call this the tribal social instincts hypothesis. The evolution of complex societies in the past few thousand years constitutes a series of natural experiments that test this hypothesis. If it is correct, the institutions of complex societies must somehow take advantage of the prosocial elements of the tribal instincts while finessing the problem that the tribal social instincts are ill adapted to life in large, hierarchical, inegalitarian societies with extensive dominance of subordinates by elites..

AIDSThe sudden appearance of a truly new disease is a wake-up call. A new global pandemic of an infectious agent, transmitted through sexual contact and blood, affecting alienated and/or deprived people and communities, infectious throughout, that causes a slowly progressive breakdown of defence against other infectious diseases, as well as causing dementia in some, and leads to a premature death, occurring in an era of extensive travel and rapid communication, is a veritable tocsin. These crude ingredients of AIDS as a (...) medical and social phenomenon, blended with the poignant personal histories revealed to clinical professionals, spiced — as if this were necessary — by the fear, the prejudice, the wild theorising and the voyeurism, have presented a substantial challenge to practical medical ethics.Familiar ethical debates have been reopened with new perspective and insight, others have been examined thoroughly for the first time. Building on the major developments in medical ethics over recent decades, AIDS has provided an opportunity, indeed a necessity, for its maturation. It continues to present new issues for debate, while those that were present from the outset continue to perplex us, as this issue of the journal should show. In teaching, AIDS offers a plethora of examples to illustrate most of the central tenets and tensions of medical ethics. As an exemplar, it has provided preparation and precedent for addressing some of the issues emerging from new challenges, such as screening for susceptibility to genetic disease.AJPBereavementThe word comes from the same germanic root as “to be robbed excessively”. Bereavement is an intensely personal and disorienting experience, to which people can react with denial, anger, guilt or depression, sometimes prolonged. In Western countries nowadays it is most commonly experienced in mid-life through the death of a parent, or in old age through that of a …. (shrink)

Religion and faith dominated much of Newton's life and work. His papers, never made available to the public, were filled with biblical speculation and timelines along with passages that excoriated the early Church fathers. Indeed, his radical theological leanings rendered him a heretic, according to the doctrines of the Anglican Church.

Creativity: Theory, History, Practice offers important new perspectives on creativity in the light of contemporary critical theory and cultural history. Innovative in approach as well as argument, the book crosses disciplinary boundaries and builds new bridges between the critical and the creative. It is organized in four parts: · Why creativity now? offers much-needed alternatives to both the Romantic stereotype of the creator as individual genius and the tendency of the modern creative industries to treat everything as a commodity. · (...) Defining creativity, creating definitions traces the changing meaning of "create" from religious ideas of divine creation from nothing to advertising notions of concept creation. It also examines the complex history and extraordinary versatility of terms such as imagination, invention, inspiration and originality. · Creation as myth, story, metaphor begins with modern re-telling of early African, American and Australian creation myths and -picking up Biblical and evolutionary accounts along the way - works round to scientific visions of the Big Bang, bubble universes and cosmic soup. · Creative practices, cultural processes is a critical anthology of materials, chosen to promote fresh thinking about everything from changing constructions of "literature" and "design" to artificial intelligence and genetic engineering. Rob Pope takes significant steps forward in the process of rethinking a vexed yet vital concept, all the while encouraging and equipping readers to continue the process in their own creative or "re-creative" ways. Creativity: Theory, History, Practice is invaluable for anyone with a live interest in exploring what creativity has been, is currently, and yet may be. (shrink)

It is almost 30 years since the sociobiology controversy burst into full bloom. The modern theory of the evolution of animal behavior was born in the mid 1960’s with Bill Hamilton’s seminal papers on inclusive fitness and George William’s book Adaptation and Natural Selection. The following decade saw an avalanche of important ideas on the evolution of sex ratio, animal conflicts, parental investment, and reciprocity, setting off a revolution our understanding of animal societies, a revolution that is still going on (...) today. By the mid-1970’s, Richard Alexander, E. O. Wilson, Napoleon Chagnon, Bill Irons, and Don Symons among others began applying these ideas to understand human behavior. Humans are evolved creatures, and quite plausibly the same evolutionary forces that shaped the behavior of other animals also molded our behavior. Moreover, the new theory of animal behavior—especially, kin selection, parental investment, and optimal foraging theory—seemed fit the data on human societies fairly well. (shrink)

Virtually every aspect of the current philosophical discussion of self-deception is a matter of controversy including its definition and paradigmatic cases. We may say generally, however, that self-deception is the acquisition and maintenance of a belief (or, at least, the avowal of that belief) in the face of strong evidence to the contrary motivated by desires or emotions favoring the acquisition and retention of that belief. Beyond this, philosophers divide over whether this action is intentional or not, whether self-deceivers recognize (...) the belief being acquired is unwarranted on the available evidence, whether self-deceivers are morally responsible for their self-deception, and whether self-deception is morally problematic (and if it is in what ways and under what circumstances). The discussion of self-deception and its associated puzzles gives us insight into the ways in which motivation affects belief acquisition and retention. And yet insofar as self-deception represents an obstacle to self-knowledge, which has potentially serious moral implications, self-deception is more than an interesting philosophical puzzle. It is a problem of particular concern for moral development, since self-deception can make us strangers to ourselves and blind to our own moral failings. (shrink)

Medical ethics, principles, persons, and perspectives is discussed under three headings: History, Theory, and Practice. Under Theory, the author will say something about some different approaches to the study and discussion of ethical issues in medicine—especially those based on principles, persons, or perspectives. Under Practice, the author will discuss how one perspectives based approach, hermeneutics, might help in relation first to everyday ethical issues and then to public controversies. In that context some possible advantages of moving from controversy to conversation (...) will be explored; and that will then be illustrated with reference to a current controversy about the use of human embryos in stem cell therapy research. The paper begins with history, and it begins in the author’s home city of Edinburgh. (shrink)

This book explores the concept of punishment: its meaning and significance, not least to those subject to it; its social, political and emotional contexts; its role in the criminal justice system; and the difficulties of bringing punishment to an end. It explores how levels of criminal punishment could and should be reduced, without compromising moral standards, public safety or the rights of victims of crime. Core contents include: Why punishment matters, the salience of emotions in its various discourses and the (...) role of culture. The politicisation of punishment and legitimacy. The penal system, the prominence of the prison in research on punishment and the role of community sanctions. The aims of punishment, its limits and the role of power. The ethics of punishment and human rights. Punishment and social order. This book is essential reading for all criminologists, as well as students taking courses on punishment, penology, prisons and the criminal justice system. (shrink)

The 3.5 Dungeon Master's Guide II sourcebook discusses player motivations such as these, recognizing that, for many, they are one of the main reasons to play DD. The actor plays a character that someone else has envisioned and written: a figment of someone else's imagination. The author's task looks at the other side of this coin: an author conceives of a world and characters, and then sees (...) how those characters will react to their circumstances. The very chapter owes its existence to one from whom the author learned that he had the capacity for courage and faith, to Lady Yui – to my other self. (shrink)

In the first work of investigative journalism in decades to give a comprehensive view into contemporary psychiatric incarceration and forced interventions, Your Consent Is Not Required exposes how rising numbers of people from many walks of life are being subjected against their will to surveillance, indefinite detention, and powerful tranquilizing drugs, restraints, seclusion, and electroshock.

This article examines how the availability of Big Data, coupled with new data analytics, challenges established epistemologies across the sciences, social sciences and humanities, and assesses the extent to which they are engendering paradigm shifts across multiple disciplines. In particular, it critically explores new forms of empiricism that declare ‘the end of theory’, the creation of data-driven rather than knowledge-driven science, and the development of digital humanities and computational social sciences that propose radically different ways to make sense of culture, (...) history, economy and society. It is argued that: Big Data and new data analytics are disruptive innovations which are reconfiguring in many instances how research is conducted; and there is an urgent need for wider critical reflection within the academy on the epistemological implications of the unfolding data revolution, a task that has barely begun to be tackled despite the rapid changes in research practices presently taking place. After critically reviewing emerging epistemological positions, it is contended that a potentially fruitful approach would be the development of a situated, reflexive and contextually nuanced epistemology.

In his profound and deeply personal new book, New York Times bestselling author Rob Bell explores the endless dynamic questions and connections that have shaped his life to provide powerful insight into understanding your purpose and place in the world. Our home is a universe of endless dynamic connections that never stop inviting us to participate in the great mysterious love at the heart of it all. Everything is Spiritual is a brief history of how these ideas about creation, love, (...) and connection shaped the author--and can shape every one of us. In this book, Rob Bell explores the concept that what people really want, more than anything, is to understand their purpose here--so much so that it gives them an abiding sense of awe and wonder. And when you embrace where and who you come from and your wounds and pains and regrets, you will discover that there's an invitation lurking there in the mess of life: an invitation to expand just like the universe has been doing for 13 billions years. There is a space beyond all the parts and divisions and differences and polarization where you see that it's all one connected whole and it's all rigged in favor of your growth, expansion, and joy.

The book provides a detailed yet clear introduction to the sociology of Basil Bernstein that will be accessible to those not already familiar with it, but also of interest to those who are. It locates his thinking within the history of the field of British sociology in his life-time, explores the classical sources in Durkheim and Marx, and shows how a world-wide network of scholars continues to apply and further develop his ideas. His later ideas about knowledge structures are applied (...) to Bernstein himself in terms of a historical analysis of the fields of British sociology and the sociology of education and his position within them. The book is, in this way, about British sociology and education as well as about Bernstein and intends to provide a provocative and challenging account of both. The book is organised in four main sections that deal with: theory, research, control and pedagogy. It explores the major areas of his work and shows their inter-relatedness and their development over time. Although Bernstein had a special interest in education, he did not see himself a sociologist of education alone. His was a broad and wide-ranging programme in the social sciences and it is in these terms that his work is presented in this book. (shrink)

It is widely acknowledged that individual moral obligations and responsibility entail shared (or joint) moral obligations and responsibility. However, whether individual epistemic obligations and responsibility entail shared epistemic obligations and responsibility is rarely discussed. Instead, most discussions of doxastic responsibility focus on individuals considered in isolation. In contrast to this standard approach, I maintain that focusing exclusively on individuals in isolation leads to a profoundly incomplete picture of what we're epistemically obligated to do and when we deserve epistemic blame. First, (...) I argue that we have epistemic obligations to perform actions of the sort that can be performed in conjunction with other people, and that consequently, we are often jointly blameworthy when we violate shared epistemic obligations. Second, I argue that shared responsibility is especially important to doxastic responsibility thanks to the fact that we don't have the same kind of direct control over our beliefs that we have over our actions. In particular, I argue that there are many cases in which a particular individual who holds some problematic belief only deserves epistemic blame in virtue of belonging to a group all the members of which are jointly blameworthy for violating some shared epistemic obligation.

Some conspicuous characteristics of argumentation as we all know this phenomenon from our shared everyday experiences are in my view vital to its theoretical treatment because they should have methodological consequences for the way in which argumentation research is conducted. To start with, argumentation is in the first place a communicative act complex, which is realized by making functional verbal communicative moves.

This article is about a sidebar in James Gibson's last book, The ecological approach to visual perception. In this sidebar, Gibson, the founder of the ecological perspective of perception and action, argued that to perceive an affordance is not to classify an object. Although this sidebar has received scant attention, it is of great significance both historically and for recent discussions about specificity, direct perception, and the functions of the dorsal and ventral streams. It is argued that Gibson's acknowledgment of (...) Wittgenstein's ideas of classification suggests a limited scope of his theory of direct perception?it cannot account for the classification of objects. The implications for both the specification debate and theorizing about the brain's dorsal and ventral pathways are explored. Based on a recent ecological conception of information and direct perception, we ultimately argue that both affordance perception and classification are direct. (shrink)

Some people (e.g., Drs. Paul and Susan Lim) and, with them, organizations (e.g., the National Embryo Donation Center) believe that, morally speaking, the death of a frozen human embryo is a very bad thing. With such people and organizations in mind, the question to be addressed here is as follows: if one believes that the death of a frozen embryo is a very bad thing, ought, morally speaking, one prevent the death of at least one frozen embryo via embryo adoption? (...) By way of a three‐premise argument, one of which is a moral principle first introduced by Peter Singer, my answer to this question is: at least some of those who believe this ought to. (Just who the “some” are is identified in the paper.) If this is correct, then, for said people, preventing the death of a frozen embryo via embryo adoption is not a morally neutral matter; it is, instead, a morally laden one. Specifically, their intentional refusal to prevent the death of a frozen embryo via embryo adoption is, at a minimum, morally criticizable and, arguably, morally forbidden. Either way, it is, to one extent or another, a moral failing. (shrink)
