We suggest there is somewhat more potential than Christiansen & Chater (C&C) allow for genetic adaptations specific to language. Our uniquely cooperative social system requires sophisticated language skills. Learning and performance of some culturally transmitted elements in animals is genetically based, and we give examples of features of human language that evolve slowly enough that genetic adaptations to them may arise.

Languages spoken in larger populations are relatively simple. A possible explanation for this is that languages with a greater number of speakers tend to also be those with higher proportions of non‐native speakers, who may simplify language during learning. We assess this explanation for the negative correlation between population size and linguistic complexity in three experiments, using artificial language learning techniques to investigate both the simplifications made by individual adult learners and the potential for such simplifications to influence group‐level language (...) characteristics. In Experiment 1, we show that individual adult learners trained on a morphologically complex miniature language simplify its morphology. In Experiment 2, we explore how these simplifications may then propagate through subsequent learning. We use the languages produced by the participants of Experiment 1 as the input for a second set of learners, manipulating (a) the proportion of their input which is simplified and (b) the number of speakers they receive their input from. We find, contrary to expectations, that mixing the input from multiple speakers nullifies the simplifications introduced by individuals in Experiment 1; simplifications at the individual level do not result in simplification of the population's language. In Experiment 3, we focus on language use as a mechanism for simplification, exploring the consequences of the interaction between individuals differing in their linguistic competence (as native and non‐native speakers might). We find that speakers who acquire a more complex language than their partner simplify their language during interaction. We ultimately conclude that adult learning can result in languages spoken by more people having simpler morphology, but that idiosyncratic simplifications by non‐natives do not offer a complete explanation in themselves; accommodation—by comparatively competent non‐natives to less competent speakers, or by native speakers to non‐natives—may be a key linking mechanism.

Many human cultural traits become increasingly beneficial as they are repeatedly transmitted, thanks to an accumulation of modifications made by successive generations. But how do later generations typically avoid modifications which revert traits to less beneficial forms already sampled and rejected by earlier generations? And how can later generations do so without direct exposure to their predecessors' behavior? One possibility is that learners are sensitive to cues of non‐random production in others' behavior, and that particular variants (e.g., those containing structural (...) regularities unlikely to occur spontaneously) have been produced deliberately and with some effort. If this non‐random behavior is attributed to an informed strategy, then the learner may infer that apparent avoidance of certain possibilities indicates that these have already been sampled and rejected. This could potentially prevent performance plateaus resulting from learners modifying inherited behaviors randomly. We test this hypothesis in four experiments in which participants, either individually or in interacting dyads, attempt to locate rewards in a search grid, guided by partial information about another individual's experience of the task. We find that in some contexts, valid inferences about another's behavior can be made from partial information, and these inferences can be used in a way which facilitates trait adaptation. However, the benefit of these inferences appears to be limited, and in many contexts—including some which have the potential to make inferring the experience of another individual easier—there appears to be no benefit at all. We suggest that inferring previous behavior from partial social information plays a minimal role in the adaptation of cultural traits. (shrink)

Although evidence of teaching behaviour has been identified in some nonhuman species, human teaching appears to be unique in terms of both the breadth of contexts within which it is observed, and in its responsiveness to needs of the learner. Similarly, cultural evolution is observable in other species, but human cultural evolution appears strikingly distinct. This has led to speculation that the evolutionary origins of these capacities may be causally linked. Here we provide an overview of contrasting perspectives on the (...) relationship between teaching and cultural evolution in humans, and briefly review previous research which suggests that cumulative culture can occur without teaching. We then report the results of a novel experimental study in which we investigated how the benefits of teaching may depend on the complexity of the skill to be acquired. Participants were asked to tie knots of varying complexity. In our Teaching condition, opportunities to interact with an experienced partner aided transmission of the most complex knots, but not simpler equivalents, relative to exposure to completed products alone, and also relative to information about the process of completion. We conclude by considering the plausibility of various accounts of the evolutionary relationship between teaching and cultural evolution in humans. (shrink)

The article reconsiders the nature and location of science in the development of genetic classification. Drawing on field studies of medical genetics, we explore how patient categorization is accomplished in between the clinic and laboratory. We focus on dysmorphology, a specialism concerned with complex syndromes that impair physical development. We show that dys-morphology is about more than fitting patients into prefixed diagnostic categories and that diagnostic process is marked by moments of uncertainty, ambiguity, and deferral. We describe how different forms (...) of evidence are brought into play and how patterns of physical features are identified as genetic or not. We suggest that clinical categorical work helps articulate the genetic as an emergent domain of medical classification and that moments of ambiguity and deferral create an imperative space that helps legitimate the need for more technoscience, and consequently, more clinical judgment with which to fix the genetic future.

In The Structure of Science, Ernest Nagel finds fault with Werner Heisenberg’s explication of the uncertainty principle. Nagel’s complaint is that this principle does not follow from the impossibility of measuring with precision both the position and the momentum of a particle, as Heisenberg intimates, rather it is the other way around. Recent developments in theoretical physics have shown that Nagel’s argument is more substantial than he could have envisaged. In particular it has become clear that there are in fact (...) two uncertainty principles; as a result, there are four pairs of quantities to examine, whereas Heisenberg considers only one. These findings throw new light on Nagel’s criticism. They enable us to see that his intuition was surprisingly apposite, but also make clear where his argument misses the mark. (shrink)

Richard C. Atkinson’s eight-year tenure as president of the University of California reflected the major issues facing California itself: the state’s emergence as the world’s leading knowledge-based economy and the rapidly expanding size and diversity of its population. As this selection of President Atkinson’s speeches and papers reveals, his administration was marked by innovative approaches that deliberately shaped U.C.’s role in this changing California. These writings tell the story of the national controversy over the SAT and Atkinson’s (...) successful challenge to the dominance of the seventy-five-year-old college entrance examination. They also highlight other issues with national significance: U.C.’s experiments with race-neutral admissions programs; the challenges facing academic libraries and the University’s pioneering activities with the California Digital Library; and the University’s involvement in new paradigms of industry-university research. Together, these speeches and papers open a window on an eventful period in the history of the nation’s leading public research university and the history of American higher education. (shrink)

Hume's Reception in Early America: Expanded Edition brings together the original American responses to one of Britain's greatest men of letters, David Hume. Now available as a single volume paperback, this new edition includes updated further readings suggestions and dozens of additional primary sources gathered together in a completely new concluding section. From complete pamphlets and booklets, to poems, reviews, and letters, to extracts from newspapers, religious magazines and literary and political journals, this book's contents come from a wide variety (...) of sources published in colonial America and the early United States between 1758 and 1850. As well as classics by Thomas Jefferson, John Adams and Alexander Hamilton, it contains scores of unknown and hard-to-locate items, many of which have not been reprinted since their original publication. These responses are divided into four parts covering Hume's Essays; his Philosophical Writings; his History of England; and his Character and Death. Each of those parts has a separate introductory essay, and every selection is introduced by a short headnote that sets the piece in its historical context and provides bibliographical references. Packed with new insights into Hume and American thought and culture, Hume's Reception in Early America reveals the relevance and impact of Hume on American political, philosophical, historical, religious, and aesthetic debates.

This paper offers a new way to make sense of disagreement expansion from a polylogical perspective by incorporating various places in addition to players and positions into the analysis. The concepts build on prior implicit ideas about disagreement space by suggesting how to more fully account for argumentative context, and its construction, in large-scale complex controversies. As a basis for our polylogical analysis, we use a New York Times news story reporting on an oil train explosion—a significant point in the (...) broader controversy over producing oil and gas via hydraulic fracturing.

A specific issue for argumentation theory is whether information and communication technologies play any role in governing argument — that is, as parties engage in practical activities across space and time via ICTs, does technology matter for the interplay of argumentative content and process in managing disagreement? The case made here is that technologies do matter because they are not merely conduits of communication but have a role in the pragmatics of communication and argumentation. In particular, ICTs should be recognized (...) as communication-information services that are delegated degrees of responsibility for managing disagreements arising from practical activities. These services are organized around practical theories for designing disagreement space. However, recognizing this relationship between argument and technology requires accounting for procedures, techniques, or rules and speech acts that are not argumentative propositions in any strict sense but that are consequential for what becomes argumentation in any setting. An account about designing disagreement space, grounded in Jackson and Jacobs’s theory of Disagreement Management, is put forward to address these issues while more generally contributing to understanding argument in context.

It is time to bring the rich resources of these traditions into the contemporary debate about the nature of self. This volume is the first of its kind.

In Chapter 4 of his essay Utilitarianism, “Of what sort of Proof the Principle of Utility is susceptible,” J. S. Mill undertakes to prove, in some sense of that term, the principle of utility. It has very commonly been argued that in the course of this “proof” Mill commits two very obvious fallacies. The first is the naturalistic fallacy which he is held to commit when he argues that since “the only proof capable of being given that an object is (...) visible, is that people actually see it. The only proof that a sound is audible is that people hear it: and so of the other sources of our experience. In like manner … the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it.”1 Here Mill appears to hold that “X is desirable ”—a value judgment—follows deductively from “People desire x”—a factual statement. And the second is the fallacy of composition which seems to be involved in Mill'zs argument that since “each person's happiness is a good to that person … the general happiness, therefore, a good to the aggregate of all persons.”2.

There is growing interest in examining dark personality traits, to better explain malevolent and self-serving behaviour patterns commonly observed in clinical and non-clinical settings. Recently, taxonomies of dark personalities have been developed, along with psychometric tools to measure and delineate between traits including psychopathy, Machiavellianism and narcissism. The extent to which these constructs are distinct or overlapping remains controversial. Psychophysiological research can improve understanding of biological mechanisms contributing to personality that may help to evaluate taxonomies. This study investigated diurnal variations (...) in salivary cortisol (on waking, cortisol awakening response, and at bedtime, over two days) and their relationship to personality traits (Short Dark Triad Scale and IPIP Mini), psychopathology (Depression, Anxiety and Stress Scale; DASS) and quality of life (WHOQOL-BREF) in a non-clinical sample (N=45, 26 females, 19 males, 18-59 years). Dark personality traits correlated with low bedtime cortisol, reduced sleep, depression and poorer quality of life. Hierarchical linear regressions analyses indicated that bedtime cortisol levels significantly accounted for variance in Psychopathy (F(1,39)=5.55, p=.02, R=.52, B=-1.81, 95% CI [-3.37-(-.26)], β=-.33, sr2=.10) and reduced sleep uniquely accounted for variance Machiavellianism (F(2,40)=5.99, p=.01, R=.48, B=1.01, 95% CI [.16-2.02], β=.34, sr2=.11). These data provide preliminary evidence that supports the cortisol hypoarousal hypothesis of Psychopathy and has identified a link between Machiavellianism, sleep-wake cycles, and chronotype. The hypoarousal hypothesis of Psychopathy contends that the hypothalamic-pituitary-adrenal axis is unresponsive to the stress of social engagement. Machiavellianism was predicted by longer days with evidence for an evening chronotype. These findings indicated that the Dark Triad traits have different underlying biological mechanisms that require further exploration. (shrink)

In 1956, Hans Selye tentatively suggested that the scientific study of stress could ‘help us to formulate a precise program of conduct’ and ‘teach us the wisdom to live a rich and meaningful life’. Nearly two decades later, Selye expanded this limited vision of social order into a full-blown philosophy of life. In Stress without Distress, first published in 1974, he proposed an ethical code of conduct designed to mitigate personal and social problems. Basing his arguments on contemporary understandings of (...) the biological processes involved in stress reactions, Selye referred to this code as ‘altruistic egotism’. This article explores the origins and evolution of Selye’s ‘natural philosophy of life’, analysing the links between his theories and adjacent intellectual developments in biology, psychosomatic and psychosocial medicine, cybernetics and socio-biology, and situating his work in the broader cultural framework of modern western societies.

It is argued here that large-scale organization and networked computing enable new divisions of communicative work aimed at shaping the content, direction, and outcomes of societal conversations. The challenge for argumentation theory and practice lies in attending to these new divisions of communicative work in constituting contemporary argumentative realities. Goffman’s conceptualization of participation frameworks and production formats are applied to articulate the communicative work of organizations afforded by networked computing that invents and innovates argument in all of its senses—as product, (...) process, and procedure. Communicative work, however, may be scaffolding argumentative contexts and practices that are quite different than what has constituted past argumentative realities. The computerization of argument happens as organizations invent and innovate argument practice relative to the demands and opportunities of interorganizational communication. The cases and examples examined here suggest that argument practice is evolving around the logic of conversation and the principle of personalization. The analysis challenges argumentation theory to seriously engage with the construction of communicative contexts and the realization of ideas about disagreement management in organizational practice and information infrastructures. Directions for integrating insights from a design perspective on argument with insights from organizational and information systems theory are proposed for coming to terms with an era of large-scale organization and computerization, in particular the evolution of argument practice, the inscription of argument in the built environment, and the absorption of socio-cultural argument practices by organizations and computation.

Since the 1960s, many artists have incorporated ecological concerns into their work, an endeavor that has required new strategies in art-making. To explore recent American manifestations of these interests, the David and Alfred Smart Museum commissioned new projects from artists Mark Dion, Peter Fend, and Dan Peterman, each focusing on interrelationships between particular organisms—human beings-and a specific group of sites—a museum building, a river landscape, and a university campus. The results, exhibited at the Smart Museum during the summer of (...) 2000, evoke the varied scales, from the microscopic to the global, at which human actions affect the environment. This catalog documents each of the artists' projects through an array of images and words: Smart Museum Associate Curator Stephanie Smith provides an introduction and brief overviews of the three projects, each of the artists contribute statements, and photographers Susan Anderson and Tom van Eynde document—in over 100 images—the processes and projects that comprise the exhibition.

A revelatory new theory of consciousness that returns emotions to the center of mental life. For Mark Solms, one of the boldest thinkers in contemporary neuroscience, discovering how consciousness comes about has been a lifetime's quest. Scientists consider it the "hard problem" because it seems an impossible task to understand why we feel a subjective sense of self and how it arises in the brain. Venturing into the elementary physics of life, Solms has now arrived at an astonishing answer. (...) In The Hidden Spring, he brings forward his discovery in accessible language and graspable analogies. Solms is a frank and fearless guide on an extraordinary voyage from the dawn of neuropsychology and psychoanalysis to the cutting edge of contemporary neuroscience, adhering to the medically provable. But he goes beyond other neuroscientists by paying close attention to the subjective experiences of hundreds of neurological patients, many of whom he treated, whose uncanny conversations expose much about the brain's obscure reaches. Most importantly, you will be able to recognize the workings of your own mind for what they really are, including every stray thought, pulse of emotion, and shift of attention. The Hidden Spring will profoundly alter your understanding of your own subjective experience. (shrink)

The first issue of Artificial Intelligence and Law journal was published in 1992. This paper provides commentaries on nine significant papers drawn from the Journal’s second decade. Four of the papers relate to reasoning with legal cases, introducing contextual considerations, predicting outcomes on the basis of natural language descriptions of the cases, comparing different ways of representing cases, and formalising precedential reasoning. One introduces a method of analysing arguments that was to become very widely used in AI and Law, namely (...) argumentation schemes. Two relate to ontologies for the representation of legal concepts and two take advantage of the increasing availability of legal corpora in this decade, to automate document summarisation and for the mining of arguments.

A major objection to epistemic infinitism is that it seems to make justification impossible. For if there is an infinite chain of reasons, each receiving its justification from its neighbour, then there is no justification to inherit in the first place. Some have argued that the objection arises from misunderstanding the character of justification. Justification is not something that one reason inherits from another; rather it gradually emerges from the chain as a whole. Nowhere however is it made clear what (...) exactly is meant by emergence. The aim of this paper is to fill that lacuna: we describe a detailed procedure for the emergence of justification that enables us to see exactly how justification surfaces from a chain of reasons.

Bioinformatics – the so-called shotgun marriage between biology and computer science – is an interdiscipline. Despite interdisciplinarity being seen as a virtue, for having the capacity to solve complex problems and foster innovation, it has the potential to place projects and people in anomalous categories. For example, valorised ‘outputs’ in academia are often defined and rewarded by discipline. Bioinformatics, as an interdisciplinary bricolage, incorporates experts from various disciplinary cultures with their own distinct ways of working. Perceived problems of interdisciplinarity include (...) difficulties of making explicit knowledge that is practical, theoretical, or cognitive. But successful interdisciplinary research also depends on an understanding of disciplinary cultures and value systems, often only tacitly understood by members of the communities in question. In bioinformatics, the ‘parent’ disciplines have different value systems; for example, what is considered worthwhile research by computer scientists can be thought of as trivial by biologists, and vice versa. This paper concentrates on the problems of reward and recognition described by scientists working in academic bioinformatics in the United Kingdom. We highlight problems that are a consequence of its cross-cultural make-up, recognising that the mismatches in knowledge in this borderland take place not just at the level of the practical, theoretical, or epistemological, but also at the cultural level too. The trend in big, interdisciplinary science is towards multiple authors on a single paper; in bioinformatics this has created hybrid or fractional scientists who find they are being positioned not just in-between established disciplines but also in-between as middle authors or, worse still, left off papers altogether.

In his paper ‘Mind, Mortality and Material Being’ Paul Anders attempts to show that Peter van Inwagen’s materialist metaphysics of the human person, combined with the belief that human persons survive death, faces a dilemma. Either, on the one hand, van Inwagen has to accept an account of the survival of human persons across death that cannot escape the duplication objection, or, on the other hand, van Inwagen has to accept an account of the survival of human persons across death (...) that entails the possibility of that which is logically impossible and, in consequence, renders his metaphysics necessarily false. This paper is concerned with the second horn of the dilemma. In this paper, I will attempt to do two things. First, I will attempt to show that Anders’ description of van Inwagen’s ‘naked kernel’ account of the survival of human persons across death is, at times, unclear, before, second, attempting to demonstrate that there is a response that van Inwagen could give to Anders’ argument regardless of these unclarities. Consequently, I think that, at least until Anders’ description is made clearer, and until Anders tells us why van Inwagen can’t opt for the solution I propose, we should consider van Inwagen’s inclination that God can preserve a kernel that is sufficient for the survival of human persons across death to be unharmed by Anders’ argument.

This paper examines the ethical dimensions of the closure process of an English large long-stay institution for people with learning difficulties during the last quarter of the twentieth century. It does this primarily through an analysis of oral historical interview data stemming from those managers who implemented rundown. The paper illustrates the ways in which their testimonies indicate the presence of a morally infused dominant rhetoric, which was based upon the therapeutic benefits of closure, informed by the ideas of normalisation (...) and social role valorisation. However, the paper argues that this principled managerial perspective had unfortunate ethical consequences, in that it under-acknowledged, marginalised and discredited staff viewpoints which raised pertinent issues relating to the downsizing of this particular hospital.

Cooperation for the public good is vulnerable to exploitation by free-riders because it always pays individuals to exploit the social contract for their own benefit. This problem can be resolved if free-riders are punished, but punishment is itself a public good subject to free-riding. The fear of supernatural punishment hypothesis (FSPH) proposes that belief in supernatural punishment might offer a solution to this problem by deflecting the cost of punishment onto supernatural forces and thereby incentivizing cooperation. FSPH is supported empirically (...) by ethnographic data, but this work has so far focused on (1) institutional cooperative traits which may not reflect individual choices on how to behave in everyday social interactions and (2) threat of punishment from all-powerful moralizing high gods rather than other agents capable of supernatural punishment. Here, we consider the FSPH using variables which are linked to individual interaction and expand the number of variables measuring belief in different forms of supernatural punishment. Our findings do not fit these more general FSPH predictions. We suggest there may be something special about the link between moralizing high gods and institutional enforcement of cooperation that is not captured by these other variables. (shrink)
