In the Second Treatise of Government, Locke clearly intends to construct a political order that limits the harm a tyrannical ruler can do, but his account of prerogative also effectively limits the good a ruler can do. If political and paternal power are distinct, then the standard for legitimate rule is not the public good but the good as the public understands it. The significance of this distinction becomes clear when we recognize Locke’s pessimism about our ability to adequately judge (...) the public good. Locke’s reliance on the public’s judgment as the final authority, despite his expectation that we will judge badly, can be explained in practical or pedagogical terms. He further suggests that the limits to a ruler’s power follow from inherent limits on what human beings can know about the good. (shrink)

John Locke’s Some Thoughts Concerning Education emphasizes the need to develop the habit of rationally judging which desires should be fulfilled. While nurture plays an essential role in this development, nature provides the fundamental desire for self-preservation, the end in light of which reason makes its judgments. The significance of this natural element in Lockean virtue has generally been overlooked, but it becomes clear through a comparison to Aristotelian virtue. Locke rejects any virtue that would require changing our most basic (...) desires, and he does so as part of his rejection of a political order designed for such education. Locke’s account of education is not purely transformative; rather, it is intended to prevent the transformation that would be part of an Aristotelian moral education. (shrink)

This article is aimed at Foucauldian scholars and seeks to introduce them to ethnographic works that interrogate neoliberal governmentalities. As an analytic category ‘neoliberalism’ has over the last two decades helpfully illuminated connections between seemingly unrelated social changes occurring at multiple scales. Even earlier —in his College de France 1978-9 Birth of Biopolitics lectures, to be precise—Foucault began his engagement with neoliberalism as a dominant political force. Despite being more than three decades old, Foucault’s analysis of neoliberal rationalities remains fresh (...) and insightful, which perhaps explains why scholars inspired by his analytics of governmentality have been able to make major contributions to the current social science literature on neoliberalism. However, there are increasing concerns that governmentality scholars succumb to a more general tendency among social scientists to present neoliberal transformations in monolithic and linear terms. This article critically reviews contributions from a small but growing group of neo-Foucauldian researchers that avoid these tendencies. These researchers investigate the changes wrought by neoliberalism through methodologies that involve combining an analytics of governmentality with ethnographic and quasi-ethnographic methods, and in doing so they avoid deterministic, homogenous and static accounts of social transformation. By beginning with the “everyday,” these works reject the idea that neoliberal governmentality forms a coherent apparatus. Instead these ethnographies of neoliberal governmentalities focus on governmental ensembleges that link neoliberal political rationalities with non-liberal rationalities, and they explore how neoliberal thought and practice is transformed across time and space.

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

This paper provides new insights into the food security performance of long and short food chains, through an analysis of the resilience of such chains during the severe weather events that occurred in the Australian State of Queensland in early 2011. Widespread flooding cut roads and highways, isolated towns, and resulted in the deaths of people and animals. Farmlands were inundated and there were food shortages in many towns. We found clear evidence that the supermarket-based food chain delivery system experienced (...) significant difficulties in supplying food to flood-affected towns. In contrast, more localized food supply chains—which relied upon supply from growers in peri-urban areas and community-based food initiatives—remained largely intact, and provided food at a time when the supermarkets were limited in their ability to respond to consumer demand. However, on closer examination of food distribution during flooding in the regional city of Rockhampton and in the State capital, Brisbane, the demarcation of success between “long” and “short” food chains became blurred. Both types of food supply chains shared some key resilience characteristics in responding to crisis but diverged in other important ways. We argue that conceptualizing food chains in terms of key elements of resilience—scale, diversity, flexibility and cohesion—may be more fruitful than the short-long dichotomy alone. This approach is particularly useful when prioritizing food security as the basis for evaluating food system sustainability in a context of predicted increases in extreme weather events and future climate change.

ABSTRACT Human-technology interactions are omnipresent in daily life, a reality that must be faced to enact positive change without uprooting the technological systems that have come to define us. The present study develops a collective intelligence model for human-technology interaction design that aims to promote peace, prosperity, and happiness through design intentionality informed by utopian targets of radical improvement in society. Participants generated ideas, clarified and consolidated them, and then developed an interpretive structure model of the most important affordances identified (...) during the idea generation phase. Coupled with a two-pass thematic analysis of the original idea set, what emerged is a model that is informed by stakeholder users of the technologies of tomorrow. Affordance themes centered on the importance of promoting world peace through technological means, identifying and rectifying material and financial inequalities, addressing negative well-being effects in current technologies, and increasing global collaboration and eventual expansion into the cosmos.

The vast expansion of research in human-robot interactions (HRI) these last decades has been accompanied by the design of increasingly skilled robots for engaging in joint actions with humans. However, these advances have encountered significant challenges to ensure fluent interactions and sustain human motivation through the different steps of joint action. After exploring current literature on joint action in HRI, leading to a more precise definition of these challenges, the present article proposes some perspectives borrowed from psychology and philosophy showing (...) the key role of communication in human interactions. From mutual recognition between individuals to the expression of commitment and social expectations, we argue that communicative cues can facilitate coordination, prediction, and motivation in the context of joint action. The description of several notions thus suggests that some communicative capacities can be implemented in the context of joint action for HRI, leading to an integrated perspective of robotic communication.

Two types of variables impact face recognition: estimator variables that cannot be controlled and system variables that are under direct control by the criminal justice system. This article addresses some of the reasons that eyewitnesses are prone to making errors, particularly false identifications. It provides a discussion of the differences between typical facial memory and eyewitness studies and shows that the two areas generally find similar results. It reviews estimator variable effects and focuses on system variables. Traditional facial recognition researchers (...) rarely study system variables but reveal important factors that police and policy makers should consider with regard to eyewitness identification and the courts. It concludes that there is still room for considerable improvement in identification procedures and wants to encourage more system variable research as a means of reducing wrongful convictions.

How can the friction between genesis and validity be understood? Is it possible to »dissolve« it? This paper argues that the genesis/validity-problem reflects the fundamental epistemological differences between History and Philosophy, and it takes Michel Foucault's »Archeology« as a model case for this problem. Since Foucault's »archaeological« methodology, i.e. his discourse analysis, is deeply affected by these tensions, I will show, firstly, that the epistemological model for Foucault's anti-hermeneutical and genealogical approach was rooted not in philosophy, but in medicine, especially (...) in anatomy. Secondly, I will argue that the »paradoxical« position of discourse analysis, in Foucault's eyes, is necessarily a political one – i.e. as a position within political struggles. (shrink)

Aucune discussion d'ensemble des ecrits de Lyotard sur l'art n'avait ete entreprise. Or sa reflexion sur les arts - musique, cinema, peinture surtout - est une part essentielle de son oeuvre, comme en temoignent les analyses proposees dans Discours, figure, Que peindre?, Moralites postmodernes, L'Inhumain et Les Ecrits sur l'art contemporain et les artistes. Moins remarque pourtant est le fait que Lyotard a collabore avec des peintres (Monory, Guiffrey, Adami, Sam Francis, Appel, Buren, etc). Il a ete commissaire d'une exposition (...) en 1985 qui a fait date, " Les Immateriaux ", au Centre Georges-Pompidou. Plusieurs textes du volume ainsi qu'un entretien inedit avec Bernard Blistene sont consacres a cette manifestation. Pour ce livre Francoise Coblence et Michel Enaudeau ont sollicite non seulement des lecteurs avertis de Lyotard (Christine Buci-Glucksmann, Elisabeth de Fontenay, Jean-Michel Rey, Jean-Loup Thebaud, Herman Parret, Anne Cauquelin, Gerald Sfez, Jean-Claude Rolland, Claudine Eizykman et Guy Fihman, Jean-Francois Nordmann, Jean-Patrice Courtois), mais aussi de plus jeunes chercheurs (Gaelle Bernard, Frederic Fruteau de Laclos, Claire Pages, Jerome Glicenstein, Maud Pouradier, Evelyne Toussaint) qui decouvrent pour leur propre compte le travail de Lyotard sur les arts. Les contributions rassemblees analysent les concepts forges par Lyotard, tels que " figural ", "libidinal ", " sublime ", " immateriau ", " matiere ", " impresentable " " affect ", " ecriture ". A travers eux, cette pensee de l'art veut rompre avec l'esthetique au sens academique du terme pour voir ou entendre dans les oeuvres l'evenement de la couleur ou du son. C'est donc bien d'un enjeu " ontologique " qu'il y va : l'art est seul a nous presenter la frappe sensible de l'etre. (shrink)

Researchers have emphasized the value of authenticity, but not much is known about what makes a person authentic in the eyes of others. Our research takes an interpersonal perspective to examine the determinants of followers’ perceptions of leader authenticity. Building on social identity theory, we propose that two fundamental self-identifications–a leader’s sense of uniqueness and sense of belongingness–interact to influence followers’ perceptions of a leader’s authenticity via perceptions of a leader’s self-concept consistency. In a field study conducted among leader–follower dyads (...) and in a controlled laboratory experiment, we find that when a leader feels a low sense of belongingness, there is a positive relationship between a leader’s sense of uniqueness and perceptions of leader authenticity. When a leader feels a low sense of uniqueness, there is a positive relationship between a leader’s sense of belongingness and perceptions of leader authenticity. This is because followers perceive this leader as having high self-concept consistency. (shrink)

The human species is more reliant on cultural adaptation than any other species, but it is unclear how observational learning can give rise to the faithful transmission of cultural adaptations. One possibility is that teaching facilitates accurate social transmission by narrowing the range of inferences that learners make. However, there is wide disagreement about how to define teaching, and how to interpret the empirical evidence for teaching across cultures and species. In this article I argue that disputes about the nature (...) and prevalence of teaching across human societies and nonhuman animals are based on a number of deep-rooted theoretical differences between fields, as well as on important differences in how teaching is defined. To reconcile these disparate bodies of research, I review the three major approaches to the study of teaching – mentalistic, culture-based, and functionalist – and outline the research questions about teaching that each addresses. I then argue for a new, integrated framework that differentiates between teaching types according to the specific adaptive problems that each type solves, and apply this framework to restructure current empirical evidence on teaching in humans and nonhuman animals. This integrative framework generates novel insights, with broad implications for the study of the evolution of teaching, including the roles of cognitive constraints and cooperative dilemmas in how and when teaching evolves. Finally, I propose an explanation for why some types of teaching are uniquely human, and discuss new directions for research motivated by this framework. (shrink)

Building on contemporary research in embodied cognition, enactivism, and the extended mind, this book explores how social institutions in contemporary neoliberal nation-states systematically affect our thoughts, feelings, and agency. Human beings are, necessarily, social animals who create and belong to social institutions. But social institutions take on a life of their own, and literally shape the minds of all those who belong to them, for better or worse, usually without their being self-consciously aware of it. Indeed, in contemporary neoliberal societies, (...) it is generally for the worse. In The Mind-Body Politic, Michelle Maiese and Robert Hanna work out a new critique of contemporary social institutions by deploying the special standpoint of the philosophy of mind—in particular, the special standpoint of the philosophy of what they call essentially embodied minds—and make a set of concrete, positive proposals for radically changing both these social institutions and also our essentially embodied lives for the better.

Does thought precede language, or the other way around? How does having a language affect our thoughts? Who has a language, and who can think? These questions have traditionally been addressed by philosophers, especially by rationalists concerned to identify the essential difference between humans and other animals. More recently, theorists in cognitive science, evolutionary biology, and developmental psychology have been asking these questions in more empirically grounded ways. At its best, this confluence of philosophy and science promises to blend the (...) respective strengths of each discipline, bringing abstract theory to bear on reality in a principled and focused way. At its worst, it risks degenerating into a war of words, with each side employing key expressions in its own idiosyncratic way – or worse, contaminating empirical research with a priori dogmas inherited from outmoded philosophical worldviews. In Baboon Metaphysics (2007), Dorothy Cheney and Robert Seyfarth offer an analysis of baboon cognition that promises to exemplify the very best interaction of philosophical theory and empirical research. They argue that baboons have a language of thought: a language-like representational medium, which supports the sophisticated cognitive abilities required to negotiate their complex social environment. This claim is intended to be surprising in its own right, and also to shed light on the evolution of spoken language. Because our own ancestors likely lived in a similarly complex social environment, Cheney and Seyfarth propose that the earliest humans also developed language first as a cognitive medium, and that spoken language evolved as a means to express those thoughts. There are two potential difficulties here. First, ‘Language of Thought’ (LOT) is a term of art, with much associated theoretical baggage and often comparatively little careful exposition. Thus, evaluating the claim requires getting clearer about just what LOT implies in this context.. (shrink)

Prenatal genetic testing is becoming available for an increasingly broad set of diseases, and it is only a matter of time before parents can choose to test for hundreds, if not thousands, of genetic conditions in their fetuses. Should access to certain kinds of fetal genetic information be limited, and if so, on what basis? We evaluate a range of considerations including reproductive autonomy, parental rights, disability rights, and the rights and interests of the fetus as a potential future child. (...) We conclude that parents should be able to access information that could be useful during pregnancy, but that testing for non-medical information should be limited. Next, we argue that the government lacks a compelling state interest in regulating prenatal genetic testing and propose that regulation should occur through medical professional organizations. Finally, we present a framework for determining what testing physicians should recommend, offer neutrally, or not offer at all. (shrink)

Theorists often associate certain “poetic” qualities with metaphor – most especially, producing an open-ended, holistic perspective which is evocative, imagistic and affectively-laden. I argue that, on the one hand, non-cognitivists are wrong to claim that metaphors only produce such perspectives: like ordinary literal speech, they also serve to undertake claims and other speech acts with propositional content. On the other hand, contextualists are wrong to assimilate metaphor to literal loose talk: metaphors depend on using one thing as a perspective for (...) thinking about something else. I bring out the distinctive way that metaphor works by contrasting it with two other poetic uses of language, juxtapositions and “telling details,” that do fit the accounts of metaphor offered by non-cognitivists and contextualists, respectively.

BackgroundThe annual number of retracted publications in the scientific literature is rapidly increasing. The objective of this study was to determine the frequency and reason for retraction of cancer publications and to determine how journals in the cancer field handle retracted articles.MethodsWe searched three online databases (MEDLINE, Embase, The Cochrane Library) from database inception until 2015 for retracted journal publications related to cancer research. For each article, the reason for retraction was categorized as plagiarism, duplicate publication, fraud, error, authorship issues, (...) or ethical issues. Accessibility of the retracted article was defined as intact, removed, or available but with a watermark over each page. Descriptive data was collected on each retracted article including number of citations, journal name and impact factor, study design, and time between publication and retraction. The publications were screened in duplicated and two reviewers extracted and categorized data.ResultsFollowing database search and article screening, we identified 571 retracted cancer publications. The majority (76.4%) of cancer retractions were issued in the most recent decade, with 16.6 and 6.7% of the retractions in the prior two decades respectively. Retractions were issued by journals with impact factors ranging from 0 (discontinued) to 55.8. The average impact factor was 5.4 (median 3.54, IQR 1.8–5.5). On average, a retracted article was cited 45 times (median 18, IQR 6–51), with a range of 0–742. Reasons for retraction include plagiarism (14.4%), fraud (28.4%), duplicate publication (18.2%), error (24.2%), authorship issues (3.9%), and ethical issues (2.1%). The reason for retraction was not stated in 9.8% of cases. Twenty-nine percent of retracted articles remain available online in their original form.ConclusionsRetractions in cancer research are increasing in frequency at a similar rate to all biomedical research retractions. Cancer retractions are largely due to academic misconduct. Consequences to cancer patients, the public at large, and the research community can be substantial and should be addressed with future research. Despite the implications of this important issue, some cancer journals currently fall short of the current guidelines for clearly stating the reason for retraction and identifying the publication as retracted.

Awe has been defined as an emotional response to perceptually vast stimuli that overwhelm current mental structures, yet facilitate attempts at accommodation. Four studies are presented showing the information-focused nature of awe elicitors, documenting the self-diminishing effects of awe experience, and exploring the effects of awe on the content of the self-concept. Study 1 documented the information-focused, asocial nature of awe elicitors in participant narratives. Study 2 contrasted the stimulus-focused, self-diminishing nature of appraisals and feelings associated with a prototypical awe (...) experience with the self-focused appraisals and feelings associated with pride. Study 3 found that dispositional awe-proneness, but not dispositional joy or pride, was associated with low Need for Cognitive Closure, and also documented a relationship between dispositional awe and increased emphasis on membership in “universal” categories in participants’ self-concepts. Study 4 replicated the self-concept finding from Study 3 using experimentally elicited awe. Implications for future work on awe are discussed. (shrink)

In a recent BioEssays paper [W. F. Martin, BioEssays 2017, 39, 1700115], William Martin sharply criticizes evolutionary interpretations that involve lateral gene transfer into eukaryotic genomes. Most published examples of LGTs in eukaryotes, he suggests, are in fact contaminants, ancestral genes that have been lost from other extant lineages, or the result of artefactual phylogenetic inferences. Martin argues that, except for transfers that occurred from endosymbiotic organelles, eukaryote LGT is insignificant. Here, in reviewing this field, we seek to correct some (...) of the misconceptions presented therein with regard to the evidence for LGT in eukaryotes. A recent paper dismisses claims of lateral gene transfer into eukaryotic genomes. We counter the arguments made in that paper and discuss the extensive evidence for LGT in eukaryotes. (shrink)

This article presents an overview for clinician investigators on the concepts of decision-making capacity and vulnerability as related to human subjects research. Tools for capacity assessment and unacknowledged sources of vulnerability are discussed, and the practical gaps in current informed consent requirements related to impaired capacity and potential vulnerability are described. Options are suggested for research discussions when full regulatory consent is not possible and an exception from informed consent does not apply.

This book develops an intersectional feminist approach to moral responsibility. It accomplisheses four main goals. First, it outlines a concise list of the main principles of intersectional feminism. Second, it uses these principles to critique prevailing philosophical theories of moral responsibility. Third, it offers an account of moral responsibility that is compatible with the ethos of intersectional feminism. And fourth, it uses intersectional feminist principles to critique culturally normative responsibility practices. -/- This is the first book to provide an explicitly (...) intersectional feminist approach to moral responsibility. After identifying the five principles central to intersectional feminism, the author demonstrates how influential theories of responsibility are incompatible with these principles. She argues that a normatively adequate theory of blame should not be preoccupied with the agency or traits of wrongdoers; it should instead underscore, and seek to ameliorate, oppression and adversity as experienced by the marginalized. Apt blame and praise, according to her intersectional feminist account, is both communicative and functionalist. The book concludes with an extensive discussion of culturally embedded responsibility practices, including asymmetrically structured conversations and gender- and racially biased social spaces. -/- An Intersectional Feminist Approach to Moral Responsibility presents a sophisticated and original philosophical account of moral responsibility. It will be of interest to philosophers working at the crossroads of moral responsibility, feminist philosophy, critical race theory, queer theory, critical disability studies, and intersectionality theory.

In this consensus report by a diverse group of academics who conduct and/or are concerned about social and behavioral genomics (SBG) research, the authors recount the often‐ugly history of scientific attempts to understand the genetic contributions to human behaviors and social outcomes. They then describe what the current science—including genomewide association studies and polygenic indexes—can and cannot tell us, as well as its risks and potential benefits. They conclude with a discussion of responsible behavior in the context of SBG research. (...) SBG research that compares individuals within a group according to a “sensitive” phenotype requires extra attention to responsible conduct and to responsible communication about the research and its findings. SBG research (1) on sensitive phenotypes that (2) compares two or more groups defined by (a) race, (b) ethnicity, or (c) genetic ancestry (where genetic ancestry could easily be misunderstood as race or ethnicity) requires a compelling justification to be conducted, funded, or published. All authors agree that this justification at least requires a convincing argument that a study's design could yield scientifically valid results; some authors would additionally require the study to have a socially favorable risk‐benefit profile.

Metaphor is a pervasive and significant feature of language. We use metaphor to talk about the world in familiar and innovative ways, and in contexts ranging from everyday conversation to literature and scientific theorizing. However, metaphor poses serious challenges for standard philosophical theories of meaning, because it straddles so many important boundaries: between language and thought, between semantics and pragmatics, between rational communication and mere causal association. ;In this dissertation, I develop a pragmatic theory of metaphorical utterances which reconciles two (...) apparently incompatible intuitions. The first is that metaphors are vehicles for undertaking speech acts with a propositional content distinct from their conventional sentence meaning. The second is that metaphors are tools for inducing the essentially non-propositional effect of 'seeing things in a new light' or under a new aspect. These intuitions seem to be incompatible because it is assumed that only one can capture the essential function of metaphor. I propose instead that non-propositional 'seeing-as' or aspectual thought serves as the means by which speakers intend to accomplish their end of communicating content. This does not imply that speakers are not interested in and even committed to the effects of aspectual thought as well, only that it is not their sole, ultimate intention. ;In order to substantiate this proposal about how metaphor works, I develop an account of the psychological structures on which aspectual thought operates and the changes it engenders; I then show how the content of the speaker's intended speech act is determined by the aspect the sentence generates. By bringing propositional content and non-propositional aspectual thought together in this way, my account can treat the full range of metaphors, from 'ordinary' to 'poetic', within a unified theory. Armed with this account, we have the explanatory resources necessary to acknowledge both that ordinary conversational metaphors are efficient and sometimes essential vehicles for communicating determinate propositional contents, and also that rich, poetic metaphors are invitations to an open-ended contemplation of the subject under discussion. These apparently very different effects turn out to be manifestations of the same basic process of comprehension. (shrink)
