Cultural evolution depends on both innovation (the creation of new cultural variants by accident or design) and high-fidelity transmission (which preserves our accumulated knowledge and allows the storage of normative conventions). What is required is an overarching theory encompassing both dimensions, specifying the psychological motivations and mechanisms involved. The bifocal stance theory (BST) of cultural evolution proposes that the co-existence of innovative change and stable tradition results from our ability to adopt different motivational stances flexibly during social learning and transmission. (...) We argue that the ways in which instrumental and ritual stances are adopted in cultural transmission influence the nature and degree of copying fidelity and thus also patterns of cultural spread and stability at a population level over time. BST creates a unifying framework for interpreting the findings of otherwise seemingly disparate areas of enquiry, including social learning, cumulative culture, overimitation, and ritual performance. We discuss the implications of BST for competing by-product accounts which assume that faithful copying is merely a side-effect of instrumental learning and action parsing. We also set out a novel “cultural action framework” bringing to light aspects of social learning that have been relatively neglected by behavioural ecologists and evolutionary psychologists and establishing a roadmap for future research on this topic. The BST framework sheds new light on the cognitive underpinnings of cumulative cultural change, selection, and spread within an encompassing evolutionary framework. (shrink)

The bifocal stance theory (BST) of cultural evolution has prompted a wide-ranging discussion with broadly three aims: to apply the theory to novel contexts; to extend the conceptual framework; to offer critical feedback on various aspects of the theory. We first discuss BST's relevance to the diverse range of topics which emerged from the commentaries, followed by a consideration of how our framework can be supplemented by and compared to other theories. Lastly, the criticisms that were raised by a subset (...) of commentaries allow us to clarify parts of our theory. (shrink)

The deflationary aim of this book, which occupies Part I, is to show that a widely held view has little to be said for it. The constructive aim, pursued in Part II, is to make plausible a measure-theoretic account of propositional attitudes. The discussion is throughout instructive, illuminating and sensitive to the many intricacies surrounding attitude ascriptions and how they can carry information about a subject's psychology. There is close engagement with cognitive science. The book should be read by anyone (...) seriously engaged with issues about propositional attitudes.According to the widely held view, which Matthews calls the Received View, the attitude of Φing that p is a matter of standing in a computational/functional relation to an explicit Representation that expresses the proposition that p, and thinking is ‘an inferential computational process defined over one or more of these Representations that eventuates in the production of either another Representation or a behavior’. The representations are understood to be sentences in a language of thought and thus to have a compositional syntax and semantics. The theory that Matthews aims to make plausible has it that ascriptions of propositional attitudes in the form ‘X Φs that p’, ascribe a state to a person by relating that person to an abstract object that is the representative of the state in roughly the way that numbers on a scale are the measure-theoretic representations of certain physical magnitudes. We are to think of the role of ‘Jones believes that interest rates will fall’ by analogy with that of ‘Jones weighs 150lbs’. The latter depends on there being arithmetical relations defined over numbers that enable its particular assignment of a number to Jones's weight to represent physical properties that Jones has in virtue ….

The principle of natural selection is stated. It connects fitness values (actual reproductive success) with expected fitness values. The term 'adaptedness' is used for expected fitness values. The principle of natural selection explains differential fitness in terms of relative adaptedness. It is argued that this principle is absolutely central to Darwinian evolutionary theory. The empirical content of the principle of natural selection is examined. It is argued that the principle itself has no empirical biological content, but that the presuppositions of (...) its applicability are empirical. They form the empirical biological core of evolutionary theory. (shrink)

Cross-national studies of business-related ethicality frequently have concluded that Americans possess higher ethical standards than non-Americans. These conclusions have generally been based on survey responses of relatively small convenience samples of individuals in a very limited number of countries. This article reports a study of the relationship between nationality and business-related ethicality based on survey responses from more than 6300 business students attending 120 colleges and universities in 36 countries. Two well-documented determinants of business ethics (gender and religiosity) were investigated (...) as moderators of the nationality–business ethicality relationship. The major research finding is that, while statistically significant differences were found between the business-related ethicality of American survey participants and the business-related ethicality of the non-American survey participants, the magnitudes of the differences were not substantial. The results of the study suggest that (i) more empirical cross-cultural/national research is required on business-related ethicality and (ii) previous explanations for cross-cultural/national differences in ethics need to be reconsidered before further generalizations are warranted.

In this paper we explore the thesis that the role of argumentation in practical reasoning in general and legal reasoning in particular is to justify the use of defeasible rules to derive a conclusion in preference to the use of other defeasible rules to derive a conflicting conclusion. The defeasibility of rules is expressed by means of non-provability claims as additional conditions of the rules.We outline an abstract approach to defeasible reasoning and argumentation which includes many existing formalisms, including default (...) logic, extended logic programming, non-monotonic modal logic and auto-epistemic logic, as special cases. We show, in particular, that the admissibility semantics for all these formalisms has a natural argumentation-theoretic interpretation and proof procedure, which seem to correspond well with informal argumentation.

Argument teachers and scholars have frequently invoked external justification-impressing one's viewpoint upon another-as the primary social function of argument. Pluralism and fundamental disagreement in contemporary democratic societies raise questions regarding the status of argument, including the functions argument should serve. In this essay, I suggest alternatives of agenda expansion, responsibility attribution, and identity formation as important functions of argument in diverse societies. Thesealternative functions are especially important under conditions of social inequality, since they allow less powerful individuals and groups to (...) confront more powerful actors in situations where decision making is not open to all.

The author's thesis is that human rights can be substantiated on the basis of discourse theory. The argument has two steps. The first step is the justification of the rules of discourse. The second step consists in the foundation of human rights.

Biology and the social sciences share an interest in phylogeny. Biologists know that living species are descended from past species, and use the pattern of similarities among living species to reconstruct the history of phylogenetic branching. Social scientists know that the beliefs, values, practices, and artifacts that characterize contemporary societies are descended from past societies, and some social science disciplines, linguistics and cross cultural anthropology for example, have made use of observed similarities to reconstruct cultural histories. Darwin appreciated that his (...) theory of descent with modification had many similarities of pattern and process to the already well developed field of historical linguistics. In many other areas of social science, however, phylogenetic reconstruction has not played a central role. (shrink)

We will here describe a conception of truth that is robust rather than deflationist, and that differs in important ways from the most familiar robust conceptions.' We will argue that this approach to truth is intrinsically and intuitively plausible, and fares very well relative to other conceptions of truth in terms of comparative theoretical benefits and costs.

The main thesis of this article is that Kant’s concept of law is a non-positivistic one, notwithstanding the fact that his legal philosophy includes very strong positivistic elements. My argument takes as its point of departure the distinction of three elements, around which the debate between positivism and non-positivism turns: first, authoritative issuance, second, social efficacy, and, third, moral correctness. All positivistic theories are confined to the first two elements. As soon as a necessary connection between these first two elements (...) and the third element, moral correctness, is established, the picture changes fundamentally. Positivism becomes non-positivism. There exist two kinds of connections between law and morality: classifying and qualifying connections. This distinction stems from different sorts of effects that moral defects give rise to. A classifying connection leads to the loss of legal validity, whereas a qualifying connection leads only to legal defectiveness. In Kant’s theory of law both connections are found. The qualifying connection is conspicuous throughout Kant’s theory of law, whereas the classifying connection, by contrast, is rare and well hidden. This will suffice to consider Kant as a representative of inclusive non-positivism. (shrink)

This is a condensed version of the material in chapters 8-10 in Meaning and Mental Representation (MIT, 1989). It is an explanation and defence of a theory of content for the mind considered as a symbolic computational process. It is a view i abandoned shortly thereafter when I abandoned symbolic computatioalism as a viable theory of cognition.

Many in science are disposed not to take biosemiotics seriously, dismissing it as too anthropomorphic. Furthermore, biosemiotic apologetics are cast in top-down fashion, thereby adding to widespread skepticism. An effective response might be to approach biosemiotics from the bottom up, but the foundational assumptions that support Enlightenment science make that avenue impossible. Considerations from ecosystem studies reveal, however, that those conventional assumptions, although once possessing great utilitarian value, have come to impede deeper understanding of living systems because they implicitly depict (...) the evolution of the universe backward. Ecological dynamics suggests instead a smaller set of countervailing postulates that allows evolution to play forward and sets the stage for tripartite causalities, signs, and interpreters—the key elements of biosemiosis—to emerge naturally out of the interaction of chance with configurations of autocatalytic processes. Biosemiosis thereby appears as a fully legitimate outgrowth of the new metaphysic and shows promise for becoming the supervenient focus of a deeper perspective on the phenomenon of life. (shrink)

In responding here to four respected colleagues I am grateful for their perceptive, and sympathetic but not uncritical, attention to my book. I discuss their comments in an order that permits me to focus first on the good and then on the right. I begin with some remarks addressed to two of my critics at once; there follow sections addressed to each of the four individually.

Kenneth Burke, arguably the most important American literary theorist of the twentieth century, helped define the theoretical terrain for contemporary literary and cultural studies. His perspectives were literary and linguistic, but his influences ranged across history, philosophy, and the social sciences. In this important and original study Robert Wess traces the trajectory of Burke's long career and situates his work in relation to postmodernity. His study is both an examination of contemporary theories of rhetoric, ideology, and the subject, and (...) an explanation of why Burke failed to complete his Motives trilogy. Burke's own critique of the 'isolated unique individual' led him to question the possibility of unique individuation, a strategy which anticipated important elements of postmodern concepts of subjectivity. Robert Wess's study is both a timely and judicious exposition of Burke's massive oeuvre, and a crucial intervention in current debates on rhetoric and human agency. (shrink)

Impartially Optimizing Consequentialism requires agents to act so as to bring about the best outcome, as judged by a preference ordering which is impartial among the needs and interests of all persons. IOC may seem to be only rational response to the recognition that one is only one person among many others with equal intrinsic moral status. A person who adopts a less impartial deontological alternative to IOC may seem to fail to take seriously the fact that other persons matter (...) in the same way that she takes herself to matter. This paper examines this ‘seductive appeal’ of IOC. It argues that IOC is not the only rational way to recognize the fact that each person matters. It presents an alternative conception of how to recognize the status of other persons as beingswho-matter, an alternative that has Kantian rather than consequentialist implications. (shrink)

This article examines the permissibility of teaching evolution in the public schools of a religiously diverse society. Science is committed to methodological naturalism, which is a limited epistemological position that is silent on issues of religious importance. The article argues that it is possible to teach evolution under the assumptions of methodological naturalism without violating the principle, of secular rationale or the neutrality principle which apply to religion in a pluralistic democracy. However, neither creationism nor Intelligent Design qualify for inclusion (...) in a science curriculum. The article ends with a discussion of philosophical and pedagogical approaches that an instructor should employ when teaching evolutionary theory. (shrink)

Can it be rational to be religious? Robert Audi gives a persuasive positive answer through an account of rationality and a rich, nuanced understanding of what religious commitment means. It is not just a matter of belief, but of emotions and attitudes such as faith and hope, of one's outlook on the world, and of commitment to live in certain ways.

To allocate resources ethically under DRGs, we need an expanded medical ethics. Appealing to traditional patient-centred principles such as beneficence and autonomy will not be sufficient. We also need to take into account the social principles of full beneficence and justice. If marginal benefits must be eliminated, clinicians should not participate in deciding who should get less care but should remain committed to their patients' interests.

The development of a framework for coding argumentations schemes in the transcripts of classroom dialogical deliberations on controversial, socioscientific topics is described. Arriving at a coding framework involved resolving a number of complex issues and challenges that are discussed in order to create practical remedies. The description of the development process is based on audio recordings and written exchanges between the authors as they attempted to resolve differences in the interpretation and application of argumentation schemes . These deliberations address theoretical (...) and practical concerns for adapting notions of argumentation schemes to the practical context of analyzing authentic classroom interactions. The framework was developed to accommodate research and curriculum development in school science education. A practical framework for analyzing argumentation in authentic classroom contexts is proposed and implications for science education and argumentation theory are raised. (shrink)

According to David Miller, duties of domestic national and global justice are of equal importance, given that nationhood is both intrinsically valuable and not inherently an unjust way of excluding outsiders. The consequence of this?split?level? view is that it may be reasonable to prioritize domestic justice in some cases, while letting demands of global justice take precedence in others, depending on a weighting model which seeks to account for the relative urgency of domestic and global claims and the extent to (...) which agents are more closely attached to compatriots than to outsiders. In this chapter, I argue against this weighting model on grounds of internal coherence with the theory set out in National responsibility and global justice. I first inquire into the conditions under which justice at home conflicts with justice in the world at large, according to Miller?s main principle of global justice? respect for basic human rights. I then show that on Miller?s own understanding of the various duties of global and domestic justice, cases of conflict rarely arise, and that when they do, there is a powerful argument for prioritizing global duties on grounds of urgency, which contradicts the reasoning of the weighting model. Finally, I address a problem arising from Miller?s basic assumption that under?fulfillment of basic human rights in poor countries only generates claims of global justice to which rich nations are under a duty to respond, following the acceptance of a scheme of remedial responsibilities to provide aid by each of these nations. The normative structure of the split?level view set out in NRGJ needs to be clarified with respect to the key question of whether nations can be held to be under a duty of justice to bring such a scheme into existence in the first place.

Making interactions between humans and artificial agents successful is a major goal of interaction design. The aim of this paper is to provide researchers conducting interaction studies a new framework for the evaluation of robot believability. By critically examining the ordinary sense of believability, we first argue that currently available notions of it are underspecified for rigorous application in an experimental setting. We then define four concepts that capture different senses of believability, each of which connects directly to an empirical (...) methodology. Finally, we show how this framework has been and can be used in the construction of interaction studies by applying it to our own work in human–robot interaction. (shrink)
