A key issue in economic discourse today is the relation between economic behaviour and morality. Few would want to deny that human beings are in some sense moral or ethical creatures, but the devil is in the detail. Should we think of economic behaviour as an essentially amoral process – a process adequately characterised by a means-ends rationality – into which any number of subjective ethical concerns or orientations may be intruded to give a particular action its determinate moral content? Or is it rather the case that our moral being runs deeper than this, in the sense that all of our behaviour – ‘economic’ or otherwise – is enabled or capacitated by a competence that is fundamentally ethical in character? With new analyses of the work of Hobbes and Smith, Dixon and Wilson offer a fresh approach to the debate surrounding economics and morality with a novel discussion of the self in economic theory. This book calls for a change in the way that the relation between economic behaviour and morality is understood – from an understanding of morality as a kind of preference that informs certain types of other-regarding behaviour, to an idea of morality as a competence that enables or, rather, conditions the possibility of all forms of human behaviour, other-regarding or not. Offering a new insight on homo economicus, this book will be of great interest to all those interested in the history of economics and of economic thought.

There is a long and tortuous history of misinterpreting Smithian social theory. After rehearsing that history we offer here a way of understanding Smith that, unlike much of recent revisionist Smith scholarship, does not further add to this confusion. Our proposal is to understand the relation between moral and economic behaviour in Smith as analogous to the way in which Habermas makes strategic (and normatively oriented) behaviour parasitic on a more basic communicative competence. Given this analogy, it is ironic that Habermas's own understanding of Smith's theory also leaves much to be desired

In Adaptation and Natural Selection, George C. Williams linked the distinction between group and individual adaptation with the distinction between group and individual selection. Williams' Principle, as we will call it, says that adaptation at a level requires selection at that level. This is a necessary but not a sufficient condition; for example, group adaptation requires group selection, but the fact that group selection influences a trait's evolution does not suffice for the resulting trait frequency to be a group adaptation. What more is required? In this paper, we describe an answer to this question that has been developed in multilevel selection theory. We also discuss an alternative framework for defining units of adaptation that violates Williams' Principle.

It is a challenge to explain how evolutionary altruism can evolve by the process of natural selection, since altruists in a group will be less fit than the selfish individuals in the same group who receive benefits but do not make donations of their own. Darwin proposed a theory of group selection to solve this puzzle. Very simply, even though altruists are less fit than selfish individuals within any single group, groups of altruists are more fit than groups of selfish individuals. If a population is subdivided into many groups that vary in their altruistic tendencies, altruism will be favored at the level of selection among groups even as it is being disfavored at the level of selection among individuals within groups. Darwin’s scenario became the basis for a theoretical framework called multilevel selection theory.

This essay provides a sketch of religion as a set of biologically and culturally evolved adaptations that enable human groups to function as adaptive units. Recent developments in evolutionary biology make such a group-level interpretation of religion more plausible than in the past. A brief survey of relevant concepts is followed by a relatively detailed interpretation of Calvinism as a religious system in which explicit behavioral prescriptions, beliefs about God and his relationship with people, and numerous social control mechanisms combined to change the city of Geneva from a collection of warring factions to a unified population

We address the following issues raised by the commentators of our target article and book: (1) the problem of multiple perspectives; (2) how to define group selection; (3) distinguishing between the concepts of altruism and organism; (4) genetic versus cultural group selection; (5) the dark side of group selection; (6) the relationship between psychological and evolutionary altruism; (7) the question of whether the psychological questions can be answered; (8) psychological experiments. We thank the contributors for their commentaries, which provide a diverse agenda for future study of evolution and morality. Our response will follow the organization of our book, distinguishing between evolutionary issues that concern fitness effects and psychological issues that concern motives.

The hypothesis of group selection fell victim to a seemingly devastating critique in 1960s evolutionary biology. In Unto Others (1998), we argue to the contrary, that group selection is a conceptually coherent and empirically well documented cause of evolution. We suggest, in addition, that it has been especially important in human evolution. In the second part of Unto Others, we consider the issue of psychological egoism and altruism -- do human beings have ultimate motives concerning the well-being of others? We argue that previous psychological and philosophical work on this question has been inconclusive. We propose an evolutionary argument for the claim that human beings have altruistic ultimate motives.

The naturalistic fallacy is mentioned frequently by evolutionary psychologists as an erroneous way of thinking about the ethical implications of evolved behaviors. However, evolutionary psychologists are themselves confused about the naturalistic fallacy and use it inappropriately to forestall legitimate ethical discussion. We briefly review what the naturalistic fallacy is and why it is misused by evolutionary psychologists. Then we attempt to show how the ethical implications of evolved behaviors can be discussed constructively without impeding evolutionary psychological research. A key is to show how ethical behaviors, in addition to unethical behaviors, can evolve by natural selection.

Evolutionary science (ES) and contextual behavioral science (CBS) have developed largely independently during the last half century. However, the earlier histories of these two bodies of knowledge are thoroughly entwined. ES provides a unifying theoretical framework for the biological sciences, and is increasingly being applied to human-related sciences. Meanwhile, CBS is concerned with influencing human behavior in a practical sense. This groundbreaking volume seeks to integrate ES and CBS to promote real, positive change in peoples' lives. Evolution and Contextual Behavioral Science offers a unique glimpse into the histories of ES and CBS, shows how they are intrinsically linked, and outlines why their integration--or, reunification--is essential. By examining these two schools of thought side by side, you'll gain an understanding of why functional and contextual approaches in CBS need to be combined with ES for both fields to advance more rapidly. Finally, rather than the sequential relationship that is typically imagined between ES and CBS, you'll discover how an integrated relationship between these two sciences will result in a better framework for understanding predicting, and influencing human behavior--back cover.

_A powerful treatise that demonstrates the existence of altruism in nature, with surprising implications for human society_ Does altruism exist? Or is human nature entirely selfish? In this eloquent and accessible book, famed biologist David Sloan Wilson provides new answers to this age-old question based on the latest developments in evolutionary science. From an evolutionary viewpoint, Wilson argues, altruism is inextricably linked to the functional organization of groups. “Groups that work” undeniably exist in nature and human society, although special conditions are required for their evolution. Humans are one of the most groupish species on earth, in some ways comparable to social insect colonies and multi-cellular organisms. The case that altruism evolves in all social species is surprisingly simple to make. Yet the implications for human society are far from obvious. Some of the most venerable criteria for defining altruism aren’t worth caring much about, any more than we care much whether we are paid by cash or check. Altruism defined in terms of thoughts and feelings is notably absent from religion, even though altruism defined in terms of action is notably present. The economic case for selfishness can be decisively rejected. The quality of everyday life depends critically on people who overtly care about the welfare of others. Yet, like any other adaptation, altruism can have pathological manifestations. Wilson concludes by showing how a social theory that goes beyond altruism by focusing on group function can help to improve the human condition.

Wilson outlines the basic principles of evolution with stories that entertain as much as they inform, and shows how, properly understood, these principles can illuminate the length and breadth of creation, from the origin of life to the nature of religion. Now everyone can move beyond the sterile debates about creationism and intelligent design to share Darwin's panoramic view of animal and human life, seamlessly connected to each other. Evolution, as Wilson explains, is not just about dinosaurs and human origins, but about why all species behave as they do--from beetles that devour their own young, to bees that function as a collective brain, to dogs that are smarter in some respects than our closest ape relatives. And basic evolutionary principles are also the foundation for humanity's capacity for symbolic thought, culture, and morality.--From publisher description.

Gossip is a subject that has been studied by researchers from an array of disciplines with various foci and methods. We measured the content of language use by members of a competitive sports team across 18 months, integrating qualitative ethnographic methods with quantitative sampling and analysis. We hypothesized that the use of gossip will vary significantly depending on whether it is used for self-serving or group-serving purposes. Our results support a model of gossip derived from multilevel selection theory that expects gossip to serve group-beneficial rules when rewards are partitioned at the group level on a scale that permits mutual monitoring. We integrate our case study with earlier studies of gossip conducted by anthropologists, psychologists, and management researchers.
