The authors demonstrate that unselfish behavior is in fact an important feature of both biological and human nature. Their book provides a panoramic view of altruism throughout the animal kingdom--from self-sacrificing parasites to the human capacity for selflessness--even as it explains the evolutionary sense of such behavior.

Humans massively depend on communication with others, but this leaves them open to the risk of being accidentally or intentionally misinformed. To ensure that, despite this risk, communication remains advantageous, humans have, we claim, a suite of cognitive mechanisms for epistemic vigilance. Here we outline this claim and consider some of the ways in which epistemic vigilance works in mental and social life by surveying issues, research and theories in different domains of philosophy, linguistics, cognitive psychology and the social sciences.

When people speak, their words never fully encode what they mean, and the context is always compatible with a variety of interpretations. How can comprehension ever be achieved? Wilson and Sperber argue that comprehension is an inference process guided by precise expectations of relevance. What are the relations between the linguistically encoded meanings studied in semantics and the thoughts that humans are capable of entertaining and conveying? How should we analyse literal meaning, approximations, metaphors and ironies? Is the ability to (...) understand speakers' meanings rooted in a more general human ability to understand other minds? How do these abilities interact in evolution and in cognitive development? MEANING AND RELEVANCE sets out to answer these and other questions, enriching and updating relevance theory and exploring its implications for linguistics, philosophy, cognitive science and literary studies.

In both biology and the human sciences, social groups are sometimes treated as adaptive units whose organization cannot be reduced to individual interactions. This group-level view is opposed by a more individualistic one that treats social organization as a byproduct of self-interest. According to biologists, group-level adaptations can evolve only by a process of natural selection at the group level. Most biologists rejected group selection as an important evolutionary force during the 1960s and 1970s but a positive literature began to (...) grow during the 1970s and is rapidly expanding today. We review this recent literature and its implications for human evolutionary biology. We show that the rejection of group selection was based on a misplaced emphasis on genes as “replicators” which is in fact irrelevant to the question of whether groups can be like individuals in their functional organization. The fundamental question is whether social groups and other higher-level entities can be “vehicles” of selection. When this elementary fact is recognized, group selection emerges as an important force in nature and what seem to be competing theories, such as kin selection and reciprocity, reappear as special cases of group selection. The result is a unified theory of natural selection that operates on a nested hierarchy of units.The vehicle-based theory makes it clear that group selection is an important force to consider in human evolution. Humans can facultatively span the full range from self-interested individuals to “organs” of group-level “organisms.” Human behavior not only reflects the balance between levels of selection but it can also alter the balance through the construction of social structures that have the effect of reducing fitness differences within groups, concentrating natural selection (and functional organization) at the group level. These social structures and the cognitive abilities that produce them allow group selection to be important even among large groups of unrelated individuals. (shrink)

The evolutionary problem of the units of selection has elicited a good deal of conceptual work from philosophers. We review this work to determine where the issues now stand.

The central problem for pragmatics is that sentence meaning vastly underdetermines speaker’s meaning. The goal of pragmatics is to explain how the gap between sentence meaning and speaker’s meaning is bridged. This paper defends the broadly Gricean view that pragmatic interpretation is ultimately an exercise in mind-reading, involving the inferential attribution of intentions. We argue, however, that the interpretation process does not simply consist in applying general mind-reading abilities to a particular (communicative) domain. Rather, it involves a dedicated comprehension module, (...) with its own special principles and mechanisms. We show how such a metacommunicative module might have evolved, and what principles and mechanisms it might contain. (shrink)

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. (shrink)

This paper questions the widespread view that verbal communication is governed by a maxim, norm or convention of truthfulness which applies at the level of what is literally meant, or what is said. Pragmatic frameworks based on this view must explain the frequent occurrence and acceptability of loose and figurative uses of language. We argue against existing explanations of these phenomena and provide an alternative account, based on the assumption that verbal communication is governed not by expectations of truthfulness but (...) by expectations of relevance, raised by literal, loose and figurative uses alike. Sample analyses are provided, and some consequences of this alternative account are explored. In particular, we argue that the notions of ‘literal meaning’ and ‘what is said’ play no useful theoretical role in the study of language use, and that the nature of explicit communication will have to be rethought. (shrink)

Our main aim in this paper is to show that constructing an adequate theory of communication involves going beyond Grice’s notion of speaker’s meaning. After considering some of the difficulties raised by Grice’s three-clause definition of speaker’s meaning, we argue that the characterisation of ostensive communication introduced in relevance theory can provide a conceptually unified explanation of a much wider range of communicative acts than Grice was concerned with, including cases of both ‘showing that’ and ‘telling that’, and with both (...) determinate and indeterminate import.

Altruism has both an evolutionary and a psychological meaning. As the term is used in evolutionary theory, a trait is deemed altruistic if it reduces the fitness of the actor and enhances the fitness of someone else. In its psychological sense, the thesis that we have altruistic ultimate motives asserts that we care about the welfare of others, not just as a means of enhancing our own well-being, but as an end in itself. In Unto Others (hereafter UO), we consider (...) both evolutionary altruism (Part I) and psychological altruism (Part II) from an evolutionary perspective. We propose a multilevel selection theory to explain how altruism can evolve from group selection, based on Darwin’s solution to the problem. Our presentation of multilevel selection theory expands the range of topics beyond altruism in other respects as well. In Part I1 of UO, we evaluate the arguments, both conceptual and empirical, that philosophers and psychologists have advanced in an attempt to choose between psychological egoism and motivational pluralism. We conclude that these arguments are inconclusive. (shrink)

On the relevance-theoretic approach outlined in this paper, linguistic metaphors are not a natural kind, and ―metaphor‖ is not a theoretically important notion in the study of verbal communication. Metaphorical interpretations are arrived at in exactly the same way as literal, loose and hyperbolic interpretations: there is no mechanism specific to metaphors, and no interesting generalisation that applies only to them. In this paper, we defend this approach in detail by showing how the same inferential procedure applies to utterances at (...) both ends of the literal-loose-metaphorical continuum, and how both literal and metaphorical utterances may create poetic effects.

The interpretation of metaphorical utterances often results in the attribution of emergent properties, which are neither standardly associated with the individual constituents in isolation nor derivable by standard rules of semantic composition. An adequate pragmatic account of metaphor interpretation must explain how these properties are derived. Using the framework of relevance theory, we propose a wholly inferential account, and argue that the derivation of emergent properties involves no special interpretive mechanisms not required for the interpretation of ordinary, literal utterances.

I examine the relationship between evolutionary definitions of altruism that are based on fitness effects and psychological definitions that are based on the motives of the actor. I show that evolutionary altruism can be motivated by proximate mechanisms that are psychologically either altruistic or selfish. I also show that evolutionary definitions do rely upon motives as a metaphor in which the outcome of natural selection is compared to the decisions of a psychologically selfish (or altruistic) individual. Ignoring the precise nature (...) of both psychological and evolutionary definitions has obscured many important issues, including the biological roots of psychological altruism. (shrink)

The Making of British Bioethics provides the first in-depth study of how philosophers, lawyers and other 'outsiders' came to play a major role in discussing and helping to regulate issues that used to be left to doctors and scientists. It details how British bioethics emerged thanks to a dynamic interplay between sociopolitical concerns and the aims of specific professional groups and individuals who helped create the demand for outside involvement and transformed themselves into influential 'ethics experts'. Highlighting this interplay helps (...) us appreciate how issues such as embryo research and assisted dying became high-profile 'bioethical' concerns in the late twentieth century, and why different groups now play a critical role in developing regulatory standards and leading public debates. The book draws on a wide range of original sources and will be of interest to historians of medicine and science, general historians and bioethicists. (shrink)

Our book Relevance (Sperber and Wilson 1986) treats utterance interpretation as a two-phase process: a modular decoding phase is seen as providing input to a central inferential phase in which a linguistically encoded logical form is contextually enriched and used to construct a hypothesis about the speaker's informative intention. Relevance was mainly concerned with the inferential phase of comprehension: we had to answer Fodor's challenge that while decoding processes are quite well understood, inferential processes are not only not understood, but (...) perhaps not even understandable (see Fodor 1983). Here we will look more closely at the decoding phase and consider what types of information may be linguistically encoded, and how the borderline between decoding and inference can be drawn. It might be that all linguistically encoded information is cut to a single pattern: all truth conditions, say, or all instructions for use. However, there is a robust intuition that two basic types of meaning can be found. This intuition surfaces in a variety of distinctions: between describing and indicating, stating and showing, saying and conventionally implicating, or between truth-conditional and non-truth-conditional, conceptual and procedural, or representational and computational meaning. In the literature, justifications for these distinctions have been developed in both strictly linguistic and more broadly cognitive terms. The linguistic justification goes as follows (see for example Recanati 1987). Utterances express propositions; propositions have truth conditions; but the meaning of an utterance is not exhausted by its truth conditions, i.e. the truth conditions of the proposition expressed. An utterance not only expresses a proposition but is used to perform a variety of speech acts. It can.. (shrink)

We argue that the presence of a word in an utterance serves as starting point for a relevance guided inferential process that results in the construction of a contextually appropriate sense. The linguistically encoded sense of a word does not serve as its default interpretation. The cases where the contextually appropriate sense happens to be identical to this linguistic sense have no particular theoretical significance. We explore some of the consequences of this view. One of these consequences is that there (...) may be many more mentally represented concepts than there are linguistically encoded concepts. (shrink)

Photography is valued as a medium for recording and visually reproducing features of the world. I seek to challenge the view that photography is fundamentally a recording process and that every photograph is a record—a view that I claim is based on a ‘single-stage’ misconception of the process. I propose an alternative, ‘multi-stage’ account in which I argue that causal registration of light is not equivalent to recording and reproducing an image. Intervention or non-intervention by photographers is more sophisticated than (...) the traditional view allows. Using the multi-stage account, I describe four models for producing photographic images and pictures. (shrink)

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. (shrink)

How are non-declarative sentences understood? How do they differ semantically from their declarative counterparts? Answers to these questions once made direct appeal to the notion of illocutionary force. When they proved unsatisfactory, the fault was diagnosed as a failure to distinguish properly between mood and force. For some years now, efforts have been under way to develop a satisfactory account of the semantics of mood. In this paper, we consider the current achievements and future prospects of the mood-based semantic programme.

Some photographs show determinate features of a scene because the photographed scene had those features. This dependency relation is, rightly, a consensus in philosophy of photography. I seek to refute many long-established theories of photography by arguing that they are incompatible with this commitment. In Section II, I classify accounts of photography as either single-stage or multi-stage. In Section III, I analyze the historical basis for single-stage accounts. In Section IV, I explain why the single-stage view led scientists to postulate (...) “latent” photographic images as a technical phenomenon in early chemical photography. In Section V, I discredit the notion of an invisible latent image in chemical photography and, in Section VI, extend this objection to the legacy of the latent image in digital photography. In Section VII, I appeal to the dependency relation to explain why the notion of a latent image makes the single-stage account untenable. Finally, I use the multi-stage account to advance debate about “new” versus “orthodox” theories of photography. (shrink)

Pragmatic processes crucially rely on background or contextual information supplied by the hearer, which may significantly affect the outcome of the comprehension process. Construed as a branch of cognitive psychology, pragmatics is the study of the cognitive systems apart from the I‐language and the parser which enable speaker and hearer (or communicator and audience) to co‐ordinate on the intended interpretation, and this is how we propose to treat it here. This chapter considers some of Noam Chomsky's suggestions about how the (...) cognitive systems underlying human abilities might be investigated. It discusses his reasons and consider how far this skepticism may be due to his particular conception of pragmatics. The chapter outlines an approach to pragmatics that seems to be compatible with his general methodology and is based on an alternative conception of pragmatics that we sketch out. (shrink)

Humans possess great capacity for behavioral and cultural change, but our ability to manage change is still limited. This article has two major objectives: first, to sketch a basic science of intentional change centered on evolution; second, to provide examples of intentional behavioral and cultural change from the applied behavioral sciences, which are largely unknown to the basic sciences community.All species have evolved mechanisms of phenotypic plasticity that enable them to respond adaptively to their environments. Some mechanisms of phenotypic plasticity (...) count as evolutionary processes in their own right. The human capacity for symbolic thought provides an inheritance system having the same kind of combinatorial diversity as does genetic recombination and antibody formation. Taking these propositions seriously allows an integration of major traditions within the basic behavioral sciences, such as behaviorism, social constructivism, social psychology, cognitive psychology, and evolutionary psychology, which are often isolated and even conceptualized as opposed to one another.The applied behavioral sciences include well-validated examples of successfully managing behavioral and cultural change at scales ranging from individuals to small groups to large populations. However, these examples are largely unknown beyond their disciplinary boundaries, for lack of a unifying theoretical framework. Viewed from an evolutionary perspective, they are examples of managing evolved mechanisms of phenotypic plasticity, including open-ended processes of variation and selection.Once the many branches of the basic and applied behavioral sciences become conceptually unified, we are closer to a science of intentional change than one might think.

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. (shrink)

_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. (shrink)

The naturalistic fallacy is mentionedfrequently by evolutionary psychologists as anerroneous way of thinking about the ethicalimplications of evolved behaviors. However,evolutionary psychologists are themselvesconfused about the naturalistic fallacy and useit inappropriately to forestall legitimateethical discussion. We briefly review what thenaturalistic fallacy is and why it is misusedby evolutionary psychologists. Then we attemptto show how the ethical implications of evolvedbehaviors can be discussed constructivelywithout impeding evolutionary psychologicalresearch. A key is to show how ethicalbehaviors, in addition to unethical behaviors,can evolve by natural selection.

Pathological Altruism presents a number of new, thought-provoking theses that explore a range of hurtful effects of altruism and empathy.

The primary outcome of natural selection is adaptation to an environment. The primary concern of epistemology is the acquistion of knowledge. Evolutionary epistemology must therefore draw a fundamental connection between adaptation and knowledge. Existing frameworks in evolutionary epistemology do this in two ways; (a) by treating adaptation as a form of knowledge, and (b) by treating the ability to acquire knowledge as a biologically evolved adaptation. I criticize both frameworks for failing to appreciate that mental representations can motivate behaviors that (...) are adaptive in the real world without themselves directly corresponding to the real world. I suggest a third framework in which mental representations are to reality as species are to ecosystems. This is a many-to-one relationship that predicts a diversity of adaptive representations in the minds of interacting people. As “species of thought”, mental representations share a number of properties with biological species, including isolating mechanisms that prevent them from blending with other representations. Species of thought also are amenable to the empirical methods that evolutionists use to study adaptation in biological species. Empirical studies of mental representations in everyday life might even be necessary for science to succeed as a normative “truth-seeking” discipline. (shrink)

This essay reviews the recently released Handbook of Philosophy of Management, using it as a jumping off point to explore some potential confusions in contemporary philosophy of management. The handbook itself, comprising 58 articles and some 1,000 pages, is a milestone for the field. At the same time, it brings a few problems into sharp relief. I argue for more clarity about the distinction between the philosophy of management and the philosophy of management research. I make the case that logic (...) as a de facto method for conducting inquiry may or may not be useful, while logic as a de jure standard for evaluating its conclusions is indispensable. I develop the view that neither management nor management studies is properly considered a science, or even an applied science. I contend that the seminal contributions of Alasdair MacIntyre are unjustly neglected by the field. And I advance the thesis that perhaps the leading issue for the philosophy of management today is the question of the purpose of management, pointing in some suggested directions for answering the question.

Chiappe and Kukla argue that relevance theory fails to solve the frame problem as defined by Fodor. They are right. They are wrong, however, to take Fodor’s frame problem too seriously. Fodor’s concerns, on the other hand, even though they are wrongly framed, are worth addressing. We argue that Relevance thoery helps address them.

In the first book-length study of American philosophy at the turn of the century, Daniel J. Wilson traces the formation of philosophy as an academic discipline. Wilson shows how the rise of the natural and physical sciences at the end of the nineteenth century precipitated a "crisis of confidence" among philosophers as to the role of their discipline. Deftly tracing the ways in which philosophers sought to incorporate scientific values and methods into their outlook and to redefine philosophy itself, Wilson (...) moves between close analysis of philosophical texts and consideration of professional careers of illustrative philosophers, such as Charles Sanders Peirce, John Dewey, and Josiah Royce. The author situates the emergence of professional philosophy in the context of the professionalization of American higher education and articulates, in the case of philosophy, the structures and values of a professional discipline. One of the most important consequences of this transformation was a new emphasis on communal theories of truth. Peirce, Dewey, and Royce all developed sophisticated and important theories of community as they were engaged in reshaping and redefining the limits of philosophy. This book will be of great importance for those interested in the history of philosophy, the rise of professions, and American intellectual and educational history, and to all those seeking to understand the contemporary revival of pragmatic thought and theories of community.

This article details the relationship between history and bioethics. I argue that historians' reluctance to engage with bioethics rests on a misreading of the field as solely reducible to applied ethics, and overlooks previous enthusiasm for historical perspectives. I claim that seeing bioethics as its practitioners see it – as an interdisciplinary meeting ground – should encourage historians to collaborate in greater numbers. I conclude by outlining how bioethics might benefit from new histories of the field, and how historians can (...) lend a fresh perspective to bioethical debates. (shrink)
