The communicative behavior of chimpanzees has been cited in support of the hypothesis that language evolved from gesture. In this commentary, I compare gestural and vocal communication in wild chimpanzees. Because the use of gesture in wild chimpanzees is limited, whereas their vocal behavior is relatively complex, I argue that wild chimpanzee behavior fails to support the gestural origins hypothesis.

The emerging neurocomputational vision of humans as embodied, ecologically embedded, social agents—who shape and are shaped by their environment—offers a golden opportunity to revisit and revise ideas about the physical and information-theoretic underpinnings of life, mind, and consciousness itself. In particular, the active inference framework makes it possible to bridge connections from computational neuroscience and robotics/AI to ecological psychology and phenomenology, revealing common underpinnings and overcoming key limitations. AIF opposes the mechanistic to the reductive, while staying fully grounded in a (...) naturalistic and information-theoretic foundation, using the principle of free energy minimization. The latter provides a theoretical basis for a unified treatment of particles, organisms, and interactive machines, spanning from the inorganic to organic, non-life to life, and natural to artificial agents. We provide a brief introduction to AIF, then explore its implications for evolutionary theory, ecological psychology, embodied phenomenology, and robotics/AI research. We conclude the paper by considering implications for machine consciousness. (shrink)

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

Extended Cognition examines the way in which features of a subject's cognitive environment can become constituent parts of the cognitive process itself. This volume explores the epistemological ramifications of this idea, bringing together academics from a variety of different areas, to investigate the very idea of an extended epistemology.

The possibility of extended cognition invites the possibility of extended knowledge. We examine what is minimally required for such forms of technologically extended knowledge to arise and whether existing and future technologies can allow for such forms of epistemic extension. Answering in the positive, we explore some of the ensuing transformations in the ethical obligations and personal rights of the resulting ‘new humans.’.

This volume explores the epistemology of distributed cognition, the idea that groups of people can generate cognitive systems that consist of all participating members. Can distributed cognitive systems generate knowledge in a similar way to individuals? If so, how does this kind of knowledge differ from normal, individual knowledge?

First, a theoretical background to the volume’s topic, extended epistemology, is provided by a brief outline of its cross-disciplinary theoretical lineage and some key themes. In particular, it is shown how and why the emergence of recent and more egalitarian thinking in the cognitive sciences about the nature of human cognizing and its bounds—viz., the so-called ‘extended cognition’ program, and the related idea of an ‘extended mind’—has important and interesting ramifications in epistemology. Second, an overview is provided of the papers (...) included as chapters in the volume. The sixteen contributions are divided into two categories: those that engage with foundational issues to do with extended epistemology, and those that pursue applications of extended epistemology to new areas of research.

One of the most important research programmes in contemporary cognitive science is that of extended cognition, whereby features of a subject's cognitive environment can in certain conditions become constituent parts of the cognitive process itself. The aim of this volume is to explore the epistemological ramifications of this idea.... The first part of the volume explores foundational issues with regard to an extended epistemology, including from a critical perspective. The second part of the volume examines the applications of extended epistemology (...) and the new theoretical directions that it might take us. These include its ethical ramifications, its import to the epistemology of education and emerging digital technologies, and how this idea might dovetail with certain themes in Chinese philosophy.

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to be a premature burial.

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

In a recent very interesting and important challenge to tracking theories of knowledge, Williams & Sinhababu claim to have devised a counter-example to tracking theories of knowledge of a sort that escapes the defense of those theories by Adams & Clarke. In this paper we will explain why this is not true. Tracking theories are not undermined by the example of the backward clock, as interesting as the case is.

ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates the (...) epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

We argue that some key examples by Kripke involving red barns and such fail to provide any counterexample to Nozick's tracking theory of knowledge.

Tristan Haze claims we have made two mistakes in replying to his two attempted counter-examples to Tracking Theories of Knowledge. Here we respond to his two recent claims that we have made mistakes in our reply. We deny both of his claims.

Since Kripke's attack on Nozick's Tracking Theory of knowledge, there has been strong suspicion that tracking theories are false. We think that neither Kripke's arguments and examples nor other recent attacks in the literature show that the tracking theories are false. We cannot address all of these concerns here, but we will show why some of the most discussed examples from Kripke do not demonstrate that the tracking theories are false.

In “Beat the (Backward) Clock,” we argued that John Williams and Neil Sinhababu’s Backward Clock Case fails to be a counterexample to Robert Nozick’s or Fred Dretske’s Theories of Knowledge. Williams’ reply to our paper, “There’s Nothing to Beat a Backward Clock: A Rejoinder to Adams, Barker and Clarke,” is a further attempt to defend their counterexample against a range of objections. In this paper, we argue that, despite the number and length of footnotes, Williams is still wrong.

We introduce the CUBISM system for the analysis and deep understanding of multi-participant dialogues. CUBISM brings together two typically separate forms of discourse analysis: semantic analysis and sociolinguistic analysis.

Why should the work of the ancient and the medievals, so far as it relates to nature, still be of interest and an inspiration to us now? The contributions to this enlightening volume explore and uncover contemporary scholarship's debt to the classical and medieval past. Thinking About the Environment synthesizes religious thought and environmental theory to trace a trajectory from Mesopotamian mythology and classical and Hellenistic Greek, through classical Latin writers, to medieval Christian views of the natural world and our (...) relationship with it. The work also offers medieval Arabic and Jewish views on humanity's inseparability from nature. The volume concludes with a study of the breakdown between science and value in contemporary ecological thought. Thinking About the Environment will be a invaluable source book for those seeking to address environmental ethics from a historical perspective. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Paradox of Disability: Responses to Jean Vanier and L’Arche Communities from Theology and the Sciences ed. by Hans S. ReindersAdam ClarkThe Paradox of Disability: Responses to Jean Vanier and L’Arche Communities from Theology and the Sciences Edited by Hans S. Reinders Grand Rapids, MI: Eerdmans, 2010. 191pp. $18.00Jean Vanier introduces this collection of essays with a concise articulation of the themes that define L’Arche communities: those with (...) impairments “cry out” for loving service, yet love involves the receptivity by which those without obvious impairments learn to claim their own good amid a vulnerability that [End Page 205] appears to be its negation. Subsequent essays expand upon these themes, drawing on a range of theological and social-scientific perspectives. Most could serve as introductions for undergraduate or graduate classes. The volume also invites disability scholars to examine whether and how this “Vanier school” has succeeded in its attempt to reimagine and serve both those with and those without obvious impairments.For Vanier’s “school,” such reimagining entails perceiving those with impairments as “teachers.” Executing this, however, is difficult. Xavier Le Pichon, for example, argues that “the disabled” help us recover positive views of dependency in “childhood innocence” and “aged suffering” (since they embody both stages). Focusing on the suffering that human beings experience before death, he claims that paleo-anthropological evidence suggests that societies evolved as their care of the disabled taught them to accept suffering. His argument, however, risks strongly identifying persons with their impairments, thus reinforcing the social construction of “disability” as a marginalizing category in discourse and policy.Moreover, this difficulty is not limited to associations with disvalue. Hans Reinders draws on Søren Kierkegaard and Hans Ulrich in a comparison of the severely disabled to the “teachers” of Matthew 6: the birds and lilies. The disabled, he argues, embody a positive image of “humanity” characterized by dependence on God and a lack of competition with others. Such an image of grace “frees” one from a political economy that drives toward rational mastery of self and world. Yet, do the severely impaired always experience and manifest such dependence? If not, are they not being used to create a “human” image for others in which they, in fact, do not appear?Kevin Reimer’s essay contains similar difficulties. For him, the instructive values are “trust” and “gracious openness.” Citing studies that demonstrate how these values sustain communities—even absent rational agreement—he argues that they should replace rationality as the chief marker of moral maturity (as exemplified, e.g., in Lawrence Kohlberg’s stages of moral development). Like Reinders, Reimer clearly wants those with cognitive impairments to be appreciated as teachers of values that displace the rationalist ones that deprecate them. However, like Reinder’s argument, this easily slides toward defining “humanity” under a certain ideal form, thereby still implicitly devaluing those who do not embody that ideal form. Also, one finds here the danger of romanticizing that is often identified with Vanier: one only sees the form and not the real person.William Gaventa and Brian Brock, however, provide a counterresponse, the first pivotal turn in the book. Gaventa argues that the discovery of another’s value as “teacher” occurs only when one has already acknowledged her as a person (104). In other words, any “form” taught must come only after one has encountered a “person,” which is understood as a complete image of human [End Page 206] value. Here Vanier’s argument for mutual receptivity becomes a fundamental anthropology that grounds an ethic. Love must serve both persons—the teacher with impairments and the learning respondent—along distinct lines of practical action (107). In addition, Gaventa argues that persons need sources of support that are both familial and private, on the one hand, and institutional and public, on the other—thus transcending the usual splits between conservatives and liberals.Brock develops a similar anthropological ethic drawing on Martin Luther. Being human together simply means “becoming neighbors” through the absolute (Christological) imputation of personal value. Brock criticizes practices that negate this neighborly bond. In particular, he rejects the view, often endorsed by genetic counselors, that bearing potentially impaired... (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Humans are an exceptionally cooperative species, but there is substantial variation in the extent of cooperation across societies. Understanding the sources of this variability may provide insights about the forces that sustain cooperation. We examined the ontogeny of prosocial behavior by studying 326 children 3–14 y of age and 120 adults from six societies (age distributions varied across societies). These six societies span a wide range of extant human variation in culture, geography, and subsistence strategies, including foragers, herders, horticulturalists, and (...) urban dwellers across the Americas, Oceania, and Africa. When delivering benefits to others was personally costly, rates of prosocial behavior dropped across all six societies as children approached middle childhood and then rates of prosociality diverged as children tracked toward the behavior of adults in their own societies. When prosocial acts did not require personal sacrifice, prosocial responses increased steadily as children matured with little variation in behavior across societies. Our results are consistent with theories emphasizing the importance of acquired cultural norms in shaping costly forms of cooperation and creating cross-cultural diversity. (shrink)

The T&T Clark Handbook of Analytic Theology provides theological and philosophical resources that demonstrate analytic theology's unique contribution to the task of theology. Analytic theology is a recent movement at the nexus of theology, biblical studies, and philosophy that marshals resources from the analytic philosophical tradition for constructive theological work. Paying attention to the Christian tradition, the development of doctrine, and solid biblical studies, analytic theology prizes clarity, brevity, and logical rigour in its exposition of Christian teaching. Each contribution (...) in this volume offers an overview of specific doctrinal and dogmatic issues within the Christian tradition and provides a constructive conceptual model for making sense of the doctrine. Additionally, an extensive bibliography serves as a valuable resource for researchers wishing to address issues in theology from an analytic perspective. (shrink)

This volume offers an array of newly commissioned essays, addressing the topic of love in the Christian tradition. Drawn from a range of expert theologians and philosophers in contemporary analytic and non-analytic theology, these essays join current debates within the theology of love, and aim to propose new avenues for future research. Including the last essay written by Marilyn McCord Adams, Love, Divine and Human deals with a rich variety of issues related to divine and human love. The broad scope (...) of the book includes divine transcendence and its methodological bearing on the doctrine of divine love, the nature and scope of divine love, the interrelation between God's love and wrath, the plausibility of an impassable God of love, and the application of various conceptions of divine love to the problem of divine hiddenness, human ethics, and human free will, among other topics. This unified collection of cutting-edge papers will advance discussion for all those focused on the theology of love. (shrink)

This book offers both the theoretical background behind the minority effect, teachers' personal experiences as they experienced being a minority, and their analyses and insights for teaching diverse learners.

Choice experiment (CE) is a questionnaire based method that the accuracy of research questionnaire determines the validity of the research outcomes. Attribute selection has a prime importance in every CE studies. If respondents do not understand or do not have preference for a certain attribute, the attribute non-attendance problem might happen that biases overall results of the research. Qualitative approaches such as literature review, focus group discussion, and in depth discussion commonly applied in CE researches. However, especially in the developing (...) countries context where ethnical and cultural diversity is a challenge in conducting survey based questionnaires, qualitative methods are not sufficient in selecting attributes. Present study investigates the application of relative importance index (RII) in respondents¡¯ preference for attributes in a modal shift study in Klang Valley, Malaysia. The 5 point Likert scale questions were employed to enhance respondents¡¯ preferences for initial 24 selected attributes. The results of this study showed that from 24 pre-selected attributes, only 18 of them had RII>0.5 and could be included in the final CE design. The results of this study could help researchers to control for unobserved problems in selecting the attributes which could not be discovered through qualitative approaches. -/- . (shrink)

On June 11, 1963, in a dramatic gesture that caught the nation's attention, Governor George Wallace physically blocked the entrance to Foster Auditorium on the University of Alabama's campus. His intent was to defy Attorney General Nicholas Katzenbach, sent on behalf of the Kennedy administration to force Alabama to accept court-ordered desegregation. After a tense confrontation, President Kennedy federalized the Alabama National Guard and Wallace backed down, allowing Vivian Malone and James Hood to become the first African Americans to enroll (...) successfully at their state's flagship university. That night, John F. Kennedy went on television to declare civil rights a "moral issue" and to commit his administration to this cause. That same night, Medgar Evers was shot dead. In The Schoolhouse Door, E. Culpepper Clark provides a riveting account of the events that led to Wallace's historic stand, tracing a tangle of intrigue and resistance that stretched from the 1940s, when the university rejected black applicants outright, to the post-Brown v. Board of Education era. We are there in July 1955 when Thurgood Marshall and lawyers at the NAACP Legal Defense Fund win for Autherine Lucy and "all similarly situated" the right to enroll at the university. We are in the car with Lucy in February 1956 as university officials escort her to class, shielding her from a mob jeering "Lynch the nigger," "Keep 'Bama white," and "hit the nigger whore." Clark exposes the many means, including threats and intimidation, used by university and state officials to discourage black applicants following the Lucy episode. And he explains how University of Alabama president Frank Anthony Rose eventually cooperated with the Kennedy administration to ensure a smooth transition toward desegregation. We also witness Robert Kennedy's remarkable face-to-face plea for Wallace's cooperation and the governor's adamant refusal: "I will never submit voluntarily to any integration in a school system in Alabama." As Clark writes, Wallace's carefully orchestrated surrender would leave the forces of white supremacy free to fight another day. And the Kennedys' public embrace of the civil rights movement would set in motion a political transformation that changed the presidential base of the Democratic party for the next thirty years. In these pages, full of courageous black applicants, fist-shaking demonstrators, and powerful politicians, Clark captures the dramatic confrontations that transformed the University of Alabama into a proving ground for the civil rights movement and gave the nation unforgettable symbols for its struggle to achieve racial justice.

Within contemporary philosophy of mind, it is taken for granted that externalist accounts of meaning and mental content are, in principle, orthogonal to the matter of whether cognition itself is bound within the biological brain or whether it can constitutively include parts of the world. Accordingly, Clark and Chalmers (Analysis 58(1):7–19, 1998) distinguish these varieties of externalism as ‘passive’ and ‘active’ respectively. The aim here is to suggest that we should resist the received way of thinking about these dividing (...) lines. With reference to Brandom’s (1994, 2000, Inquiry 47:236–253, 2008) broad semantic inferentialism, we show that a theory of meaning can be at the same time a variety of active externalism. While we grant that supporters of other varieties of content externalism (e.g., Putnam 1975 and Burge (Philosophical Review 95:3–45, 1986) can deny active externalism, this is not an option for semantic inferentialists: On this latter view, the role of the environment (both in its social and natural form) is not ‘passive’ in the sense assumed by the alternative approaches to content externalism.

While admiring the breadth and interest of Clark's discussion of a persistent theme in science fiction, I worry about its capacity to reveal fundamental features of the genre. I also try to make explicit some of Clark's unstated assumptions.

review of Glymour's *Theory and Evidence* focusing on the arguments against holism.

This chapter discusses the flaws of Clark’s extended mind hypothesis. Clark’s hypothesis assumes that the nature of the processes internal to an object has nothing to do with whether that object carries out cognitive processing. The only condition required is that the object is coupled with a cognitive agent and interacts with it in a certain way. In making this tenuous connection, Clark commits the most common mistake extended mind theorists make; alleging that an object becomes cognitive (...) once it is connected to a cognitive agent is a “coupling-constitution fallacy.” From this fallacy, many hastily proceed to the conclusion that the object or process constitutes part of the agent’s cognitive apparatus or cognitive processing.

According to reductive intellectualists about knowledge-how :147–190, 2008; Philos Phenomenol Res 78:439–467, 2009) knowledge-how is a kind of knowledge-that. To the extent that this is right, then insofar as we might conceive of ways knowledge could be extended with reference to active externalist :7–19, 1998; Clark in Supersizing the mind: embodiment, action, and cognitive extension: embodiment, action, and cognitive extension. Oxford University Press, Oxford, 2008) approaches in the philosophy of mind, we should expect no interesting difference between the two. (...) However, insofar as anti-intellectualist approaches to knowledge-how are a viable option, there is an overlooked issue of how knowledge-how might be extended, via active externalism, in ways very differently from knowledge-that. This paper explores this overlooked space, and in doing so, illustrates how a novel form of extended knowledge-how emerges from a pairing of active externalism in the philosophy of mind with anti-intellectualism in the theory of knowledge. Crucial to our argument will be a new way of thinking about the extended mind thesis, as it pertains to the kinds of state one is in when one knows how to do something, and how this state connects with non-accidentally successful performance.

Adams and Aizawa, in a series of recent and forthcoming papers,, ) seek to refute, or perhaps merely to terminally embarrass, the friends of the extended mind. One such paper begins with the following illustration: "Question: Why did the pencil think that 2+2=4? Clark's Answer: Because it was coupled to the mathematician" Adams and Aizawa ms p.1 "That" the authors continue "about sums up what is wrong with Clark's extended mind hypothesis". The example of the pencil, they suggest, (...) is just an especially egregious version of a fallacy said to pervade the literature on the extended mind. This fallacy, which they usefully dub the " coupling-constitution fallacy ", is attributed, in varying degrees and manners, to Van Gelder and Port, Clark and Chalmers, Haugeland, Dennett, Clark, Gibbs, and Wilson. The fallacy, of course, is to move from the causal coupling of some object or process to some cognitive agent, to the conclusion that the object or process is part of the cognitive agent, or part of the agent's cognitive processing ms p.2). Proponents of the extended mind and related theses, Adams and Aizawa repeatedly assert, are prone to this fallacy in part because they either ignore or fail to properly appreciate the importance of " the mark of the cognitive" viz the importance of an account of "what makes something a cognitive agent". The positive part of Adams and Aizawa's critique then emerges as a combination of the assertion that this "mark of the cognitive" involves the idea that "cognition is constituted by certain sorts of causal process that involve non-derived contents" and that these processes look to be characterized by psychological laws that turn out to apply to many internal goings-on but not currently to any processes that take place in non-biological tools and artifacts. In what follows, I shall try to show why these arguments display nothing so much as mutual failures of communication: crossed wires concealing a couple of real, important, but much more subterranean, disagreements. In particular, I try to show why the negative considerations advanced by Adams and Aizawa fail to successfully undermine the argument for the extended mind, and why their more radical positive story, unless supplemented by implausible additional claims, fails to cast doubt on the claim that minds like ours can extend into the world.

That about sums up what is wrong with Clark's view.

This is a plausible reading of what Clark and Chalmers had in mind at the time, but it is not the radical claim at stake in the extended cognition debate.[1] It is a familiar functionalist view of cognition and the mind that it can be realized in a wide range of distinct material bases. Thus, for many species of functionalism about cognition and the mind, it follows that they can be realized in extracranial substrates.[2] And, in truth, even some (...) non-functionalist views of cognition apparently allow for the possibility that cognition extends into the external world.[3] So, the (logical, conceptual, or nomological) possibility of extended cognition seems to us not the kind of radical view the advocates of this view have often implied. This is not, of course, to assess or pass judgment on the truth of these possibilities; it is only to note that they are not what most agitates people about the hypothesis of extended cognition. Framing the radical extended cognition hypothesis is a more delicate matter than framing the modal extended cognition hypothesis, but something like the following is in the ballpark. The radical extended cognition hypothesis maintains that, in many mundane cases of tool use, human cognitive processes extend into the tools. The principal reason this hypothesis is so delicate is that there remains much room for dispute about what constitutes a. (shrink)
