Subjects enrolled in studies testing high risk interventions for incurable or progressive brain diseases may be vulnerable to deficiencies in informed consent, such as the therapeutic misconception. However, the definition and measurement of the therapeutic misconception is a subject of continuing debate. Our qualitative pilot study of persons enrolled in a phase I trial of gene transfer for Parkinson disease suggests potential avenues for both measuring and preventing the therapeutic misconception. Building on earlier literature on the topic, we developed and (...) tested an interview guide that focuses on how the subjects decided to participate, emphasizing the integration of subjects’ various statements that are relevant to assessing the therapeutic misconception, rather than evaluating them as isolated statements. The results indicate that a subject’s understanding of the purpose of research is best explored in juxtaposition to the subject’s motivation for participating. (shrink)

Bioethicists have long been concerned that seriously ill patients entering early phase (‘phase I’) treatment trials are motivated by therapeutic benefit even though the likelihood of benefit is low. In spite of these concerns, consent forms for phase I studies involving seriously ill patients generally employ indeterminate benefit statements rather than unambiguous statements of unlikely benefit. This seeming mismatch between attitudes and actions suggests a need to better understand research ethics committee members’ attitudes toward communication of potential benefits and risks (...) of early phase studies to potential subjects. We surveyed the members of two U.S. research ethics committees using a phase I gene transfer study scenario, and compared the results to a previous survey of potential subjects’ perceptions and attitudes toward benefit and risk for the same protocol. The results show that there is indeed a gap between the subjects’ perceptions and the committee members’ views on what is appropriate to be communicated to research subjects. This discrepancy is the product of both the commonly assumed optimism of the subjects and to a “protective pessimism” of the research ethics committee members. We discuss this discrepancy using “frameworks of trust” and demonstrate the need to incorporate these frameworks into the existing model of informed consent. (shrink)

An investigation of public support for coastal adaptation options and public finance options in Florida evaluated stakeholder judgments and how they changed through a participatory engagement process. The study found that public finance mechanisms that imposed fiscal burdens on those who directly benefit from hazard reduction were rated as more acceptable than others. Significantly, visualisations and data on local economic damage and return on investment of potential adaptation options further increased acceptability ratings. The question of whether a development fee for (...) adaptation or any other public purpose supported by private funds is a legal issue that depends on a test called the rational nexus. One concern of this article is to explore options for such fees to cover adaptation to climate change. This raises issues about the potential conflict with the community-wide and intergenerational nature of long-term adaptation. We also explore the relevance of environmental attitudes using the 'new environmental paradigm' (NEP) scale and political party affiliation. Results have implications for infrastructure improvements that require public approval for financing. (shrink)

The volume includes topics from political philosophy and normative ethics on the one hand to philosophy of science and the philosophical underpinnings of water management policy on the other. It contains reflections on ecological nationalism, the legacy of Grey Owl, the meaning of ‘outside’ to Canadians, the paradigm shift from mechanism to ecology in our understanding of nature, the meaning of the concept of the Anthropocene, the importance of humans self-identifying as ‘earthlings’, the challenges of biodiversity protection and the status (...) of cross-bred species, how to ground the moral considerability of ecosystems, the collapse of the Newfoundland and Labrador cod fishery, and much more. It covers metaphysics, ontology, ethics, political philosophy, critical history, and environmental policy. The range of topics and frames is as diverse and challenging as the land itself. (shrink)

Canadian Environmental Philosophy is the first collection of essays to take up theoretical and practical issues in environmental philosophy today, from a Canadian perspective. The essays cover various subjects, including ecological nationalism, the legacy of Grey Owl, the meaning of “outside” to Canadians, the paradigm shift from mechanism to ecology in our understanding of nature, the meaning and significance of the Anthropocene, the challenges of biodiversity protection in Canada, the conservation status of crossbred species in the age of climate change, (...) and the moral status of ecosystems. This wide range of topics is as diverse and challenging as the Canadian landscape itself. Given the extent of humanity's current impact on the biosphere – especially evident with anthropogenic climate change and the ongoing mass extinction – it has never been more urgent for us to confront these environmental challenges as Canadian citizens and citizens of the world. Canadian Environmental Philosophy galvanizes this conversation from the perspective of this place. (shrink)

Influencing students’ educational achievements first requires understanding the underlying processes that lead to variation in students’ performance. Researchers are therefore increasingly interested in analyzing the differences in behavior displayed in educational assessments rather than merely assessing their outcomes. Such analyses provide valuable information on the differences between successful and unsuccessful students and help to design appropriate interventions. Complex problem solving (CPS) tasks have proven to provide particularly rich process data as they allow for a multitude of behaviors several of which (...) can lead to a successful performance. So far, this data has often been analyzed on a rather aggregated level looking at an average number of actions or predefined strategies. with only a few articles investigating the specific actions performed. In this paper, we illustrate and discuss a more detailed report the results of an exploratory analysis of CPS process data based on the specific actions performed.log-files that is aimed at distinguishing between students that applied the correct strategy to a problem but failed to solve it and those applying the strategy successfully. In that, the sequence of behavior displayed is reduced to interpretable parts (n-grams) that allow searching for meaningful differences between the two groups of students. This level of analysis allows finding previously undefined or unknown patterns within the data and increases our understanding of the processes underlying successful problem -solving behavior even further.

This paper is about the first (L1) and second language (L2) skills of Turkish-German dual language learners (DLLs), the interrelatedness of the L1 and L2 skills, and their relation to other selected child and family variables. The first aim of the study was to examine L1 and L2 performance and the relation between the languages. Second, the study sought to explore the conditions in which functioning dual language development can be achieved, while trying to predict the extent to which child (...) and environmental factors are related to the DLLs’ language competencies. L1 and L2 language skills of N = 69 bilingually developing 3- to 5-year-old Turkish-German children were assessed via standardized tests. In addition, information on the children’s sociodemographic variables and home language environments was obtained by means of parental questionnaires. Correlational analyses were used to examine the interrelations between L1 and L2 skills and multiple regression analyses were conducted in order to predict the children’s language competencies. The children showed age-appropriate language skills in L1 (Turkish) and lower language skills in L2 (German). Whereas their phonological memory abilities were positively correlated with L1 and L2 skills, their expressive vocabulary in L1 was negatively correlated with L2 skills. Our findings also indicated that phonological memory was a strong predictor of language abilities. Concerning family variables, both early daycare entry and stimulating home language environment were significant predictors of better L2 skills. Lastly, balanced use of both languages at home had no negative consequences on language competencies. Although more research is needed, this study shows the benefits of using a combined language measure including both L1 and L2 skills to predict DLLs’ language competencies without disregarding either of their languages.

Yarkoni's analysis clearly articulates a number of concerns limiting the generalizability and explanatory power of psychological findings, many of which are compounded in infancy research. ManyBabies addresses these concerns via a radically collaborative, large-scale and open approach to research that is grounded in theory-building, committed to diversification, and focused on understanding sources of variation.

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of (...) small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model – based on self-interest – fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life. Key Words: altruism; cooperation; cross-cultural research; experimental economics; game theory; ultimatum game; public goods game; self-interest. (shrink)

We would like to thank the commentators for their generous comments, valuable insights and helpful suggestions. We begin this response by discussing the selfishness axiom and the importance of the preferences, beliefs, and constraints framework as a way of modeling some of the proximate influences on human behavior. Next, we broaden the discussion to ultimate-level (that is evolutionary) explanations, where we review and clarify gene-culture coevolutionary theory, and then tackle the possibility that evolutionary approaches that exclude culture might be sufficient (...) to explain the data. Finally, we consider various methodological and epistemological concerns expressed by our commentators. (shrink)

Negative acknowledgement is an impression management technique that uses the admission of an unfavourable quality to mitigate a negative response. Although the technique has been clearly demonstrated, the underlying process is not well understood. The current research identifies a key mediator and moderator while also demonstrating that the effect extends beyond the specific acknowledged domain to the overall evaluation of a target object. The results of study 1 indicate that negative acknowledgement works through mitigating negatively valenced cognitive responses. People who (...) are presented with a negative acknowledgement are less likely to counterargue when forming an evaluation. The results of study 2 reveal that individual differences in need for structure impact the effectiveness of the technique. People who are high in need for structure are more susceptible to the effect presumably because of their desire for easy-to-use information that aids the formation and maintenance of simple knowledge structures.

Frank Kermode is one of our most distinguished and beloved critics of English literature. Here, he contributes a new epilogue to his collection of classic lectures on the relationship of fiction to age-old concepts of apocalyptic chaos and crisis. Prompted by the approach of the millennium, he revisits the book which brings his highly concentrated insights to bear on some of the most unyielding philosophical and aesthetic enigmas. Examining the works of writers from Plato to William Burrows, Kermode shows (...) how they have persistently imposed their "fictions" upon the face of eternity and how these have reflected the apocalyptic spirit. Kermode then discusses literature at a time when new fictive explanations, as used by Spenser and Shakespeare, were being devised to fit a world of uncertain beginning and end. He goes on to deal perceptively with modern literaturewith "traditionalists" such as Yeats, Eliot, and Joyce, as well as contemporary "schismatics," the French "new novelists," and such seminal figures as Jean-Paul Sartre and Samuel Beckett. Whether weighing the difference between modern and earlier modes of apocalyptic thought, considering the degeneration of fiction into myth, or commenting on the vogue of the Absurd, Kermode is distinctly lucid, persuasive, witty, and prodigal of ideas.

Study of the diplomacy between the Carolingians and the ʿAbbāsids has been hampered by the absence of any sources from the Caliphate commenting on their relationship. This paper identifies two variants of the Arabic Tiburtine Sibyl, apocalyptic prophecies composed by Syriac Christians in the early ninth century, that provide contemporary Arabic references to contact between Charlemagne and Hārūn al-Rashīd. In doing so, they shed new light on this diplomatic activity by indicating that it was considerably more important for the Caliph (...) than normally appreciated. Combined with other references to the Franks in Arabic apocalyptic of the period, the evidence of these Sibyls suggests that Hārūn al-Rashīd accrued considerable prestige from his reception of Charlemagne’s envoys and the gifts that they brought with them.

Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, and humane a mind; and furthermore he went further, (...) as I soon realized when I looked for his name on other publications. I recall arguing with myself over his exploration of 'Indeterminacy and Economic Development' (1948), and even more when I read his 'Dialectical Materialism and Soviet Science' (1949). More papers, and then the fascinating, sometimes irritating, always insightful, books. His monograph on Psychoanalysis and Ethics 1955, the beautiful sociological and humanist study of Spinoza and the Rise of Liberalism (1958), his essays on 'The Social Roots of Einstein's Theory of Relativity' (1971) together with the book on Einstein and the Genera tions of Science (1974), the splendid reader from the works of Marx and Engels, Basic Writings on Politics and Philosophy (1959) which was a major text of the '60s, the stimulating essays on the social formation which seems to have been required for a modern scientific movement to develop, set forth most convincingly in The Scientific Intellectual (1963).

The symposium, with which the present issue of SCE is concerned, concluded with a frank and probing discussion about the future of theological ethics. It is the purpose of this final contribution to provide a sense of the character of that debate.

In his classic monograph, The Death of Contract, Grant Gilmore argued that Christopher Columbus Langdell, Oliver Wendell Holmes, and Samuel Williston trumped up the legal credentials for their classical bargain theory of contract law. Gilmore's analysis has been subjected to extensive criticism, but its specific, sustained, and fundamental charge that the bargain theory was based on a fraudulent misrepresentation of precedential authority has never been questioned. In this Essay, I argue that Gilmore's case against the classical theorists rests (...) on the suppressed premise that the precedential authority of cases resides in the express judicial reasoning used to decide them. In contrast, I argue that the classical theorists implicitly presuppose that the precedential authority of cases consists in the best theory that explains their outcomes, even if that theory is inconsistent with the case's express judicial reasoning. The classical view of precedential authority completely defuses Gilmore's charge of fraud. In Gilmore's view, merely demonstrating the inconsistency between the proposition for which the classical theorists cited a case and the express reasoning in that case suffices as proof of misrepresentation. But in the classical theorists' view, the express reasoning in a case is simply a theory of its precedential authority, which, like any theory, can be wrong. Thus, the classical theorists simply reject Gilmore's claim that a case cannot properly be cited for a proposition inconsistent with its express reasoning. The real dispute, then, between Gilmore and the classical theorists is over the nature of precedential authority and not the content of contract law. Having reframed the classic death-of-contract debate, I then trace these competing conceptions of precedential authority through the major schools of contemporary contract theory. I argue that a contract theory's embrace of one view instead of the other can be explained by the relative priority it accords to each of the two components in a conception of adjudicative legitimacy. A conception of adjudicative legitimacy consists in a theory of what it means for a decision to be based on law and a theory of what is required for law to be justified. I explain why theories according priority to the former tend to subscribe to the precedents-as-outcomes view, while theories according priority to the latter tend to favor the express reasoning view. The Essay concludes by arguing that the economic analysis of contract law subscribes to the precedents-as-outcomes view and therefore is the contemporary jurisprudential successor to the late nineteenth-century classical theorists.

I provide a theory of the metaphysical foundations of identity: an account what grounds facts of the form a=b. In particular, I defend the claim that indiscernibility grounds identity. This is typically rejected because it is viciously circular; plausible assumptions about the logic of ground entail that the fact that a=b partially grounds itself. The theory I defend is immune to this circularity.

The terms “politics” and “political” have become so overdetermined that it is difficult to use them in any effective manner. We argue that this has dangerous political consequences, and that this could be addressed by providing a new, sounder, notion of politics. This paper argues that defining politics in relation to the notion of play can provide a notion both intuitively appealing and able to withstand the problematic overdeterminations. We argue that politics is the set of practices through which the (...) indeterminate of Spielraum is made more determinate. This suggests that politics is always partly a matter of play: it is about instituting values without making any claims about the legitimacy of this instituting act. With reference to Huizinga and Nietzsche’s analyses of play, we define play as the living unity of seriousness and frivolity, and non-play as either seriousness without frivolity or frivolity without seriousness. In order to illustrate this, we comparatively analyse the attitudes of Barack Obama and Donald Trump in the single context of the well-known yearly White House Correspondent’s Dinner. There, we see two opposed attitudes to playfulness. Our analysis allows us to apply our _Spielraum_ model of politics to show that the thrust of Obama’s attitude involves an embrace of the non-foundational nature of politics as play, whereas Trump’s attitude is politicidal: it is animated by a refusal to acknowledge its own lack of foundation, leading to an oscillation between over-seriousness and over-frivolity.

Skepticism in epistemology refers to the supposedly irrational attitude of suspending judgment about all beliefs, particularly those taken for granted. The skeptical attitude presses philosophy to investigate the conditions under which knowledge and justification rather than accidental truths can be arrived at. In the first chapter, we will investigate how to construct a form of radical skepticism known as Pyrrhonian skepticism; we will see how Agrippa's Trilemma builds three ways of skeptical defense to object to three possible conditions in the (...) structuring of epistemic justification. In the second chapter, we will examine infinitism as a possible answer to the trilemma, as well as the conceptual bases that make possible the existence of this possible solution to the skeptical challenge. In the third, the main objection to infinitism known as the finite mind problem will be analyzed. In the fourth chapter, we will look at an alternative formulation of the trilemma, as well as the challenges this approach poses to the anti-skeptical response. (shrink)

Many philosophers have thought that our folk, or pre-reflective, view of persistence is one on which objects endure. This assumption not only plays a role in disputes about the nature of persistence itself, but is also put to use in several other areas of metaphysics, including debates about the nature of change and temporal passage. In this paper, we empirically test three broad claims. First, that most people (i.e. most non-philosophers) believe that, and it seems to them as though, objects (...) persist by enduring rather than perduring. Second, that most people have a view of change on which enduring but not perduring objects count as changing. Third, that one reason why the folk represent time as dynamical is because it seems to them, and they believe that, they endure through time. We found no evidence to support these claims. While there are certainly plenty of ‘folk’ endurantists in the population we tested, there are also plenty of ‘folk’ perdurantists. We did not find robust evidence that a majority of people believed that, or it seemed to them as though, objects endure rather than perdure. We conclude that many arguments in favour of endurantism that appeal to folk beliefs about, or experiences of, persisting objects and change rest on views about those beliefs and experiences that are empirically unsupported. There is no evidence to suggest that endurantism is the folk friendly view of persistence, and so we should stop treating it as such without argument. (shrink)

This research looks what happens to human reproduction when human genetic information is digitized. By employing speculative design as a transdisciplinary strategy to construct such an alternative future to open up public dialogues, it aims to stimulate audiences in an artistic way to deliberate two key questions: (1) how will biotechnology recondition and recontextualize the natural processes of genetic information (i.e. expression, replication, transmission and mutation) and our physiological processes (e.g. reproduction)? And (2) what might be the ethical, legal and (...) social implications (ELSI) for using such biotechnology? To this end, this practice-based research introduces the ‘e-gamete Digital Procreation Service’ (2019) – a speculative design project that has been developed as an approach to invite audiences to a future scenario of network-transmitted genetic information and computer-simulated human procreation. The carefully designed future service (an ironic practice of commercialization) allows human reproduction to take place outside of the human body. Audiences are encouraged to contemplate what novel situations might occur within their own futures and to consider broader questions like how family, parenthood, marriage, etc. are redefined and what new social relationships might emerge. By employing speculative design as an artistic research tool/tactic to step outside the technical limitations and craft the future service, the project asks vital question about the future in a provocative and quasi-realistic manner. Thus, the research forms a unique entanglement of sensitive topics by dealing with future biotechnology and human reproduction. (shrink)

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., a guard might accept (...) the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

At the core of Kant's ethics lies the claim that if there is a supreme principle of morality then it cannot be a principle based on utilitarianism or Aristotelian perfectionism or the Ten Commandments. The only viable candidate for such a principle is the categorical imperative. This book is the most detailed investigation of this claim. It constructs a new, criterial reading of Kant's derivation of one version of the categorical imperative: the Formula of Universal Law. This reading shows this (...) derivation to be far more compelling than contemporary philosophers tend to believe. It also reveals a novel approach to deriving another version of the categorical imperative, the Formula of Humanity, a principle widely considered to be the most attractive Kantian candidate for the supreme principle of morality. This book will be important not just for Kant scholars but for a broad swathe of students of philosophy. (shrink)

According to many philosophers, rationality is, at least in part, a matter of one’s attitudes cohering with one another. Theorists who endorse this idea have devoted much attention to formulating various coherence requirements. Surprisingly, they have said very little about what it takes for a set of attitudes to be coherent in general. We articulate and defend a general account on which a set of attitudes is coherent just in case and because it is logically possible for the attitudes to (...) be jointly satisfied in the sense of jointly fitting the world. In addition, we show how the account can help adjudicate debates about how to formulate various rational requirements. (shrink)

One shortcoming of the chain rule is that it does not iterate: it gives the derivative of f(g(x)), but not (directly) the second or higher-order derivatives. We present iterated differentials and a version of the multivariable chain rule which iterates to any desired level of derivative. We first present this material informally, and later discuss how to make it rigorous (a discussion which touches on formal foundations of calculus). We also suggest a finite calculus chain rule (contrary to Graham, Knuth (...) and Patashnik's claim that "there's no corresponding chain rule of finite calculus"). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Wellspring or Circuit?Commentary on Dewey and the Aesthetic UnconsciousnessFrank X. RyanEditor's note: This article contains material similar to a book review by the same author previously published in The Pluralist, vol. 18, no. 2, pp 114–21. The present article represents a further critical use of this material that we deem worthy of publication.in this vital and splendidly crafted work, Bethany Henning recovers a philosophy of aesthetic wisdom far richer (...) than the narrow epistemological lens dominant today. From its start, American philosophy looked beyond Europe's atomistic empiricism toward a continuity between our thought and nature's aesthetic splendor. Jonathan Edwards found beauty in the structure of being reflected in relations among ideas. For Emerson, each of us is a "transparent eyeball" in which nature's beauty fortifies our moral and spiritual agency. At the apex of this tradition is John Dewey, for whom "aesthetic experience [is] the highest mode of human experience" (Henning 55).Although aesthetic theory is usually associated with the cognitive evaluation of art, Dewey explores a broader non-reflective or unconscious dimension. Henning's appropriation of "unconscious"—the cradle of Freud's infantile id—is intentionally provocative. American culture, reflected in academic thought, has largely resisted appeals to subterranean urges and drives. In doing so, however, we perpetuate a myth of rational and moral exceptionalism masking a history of colonialism, oppression, and crass commercialism. In accepting the unconscious, European thought has taken strides to acknowledge and address such ills. Henning wonders whether America might accept "a dynamic unconscious, were it presented with an alternative mythology" (10) and finds a viable candidate in Dewey's underappreciated notion of qualitative immediacy: an "aesthetic (directly felt) connection between ourselves and [End Page 77] the world" (Henning 5). In affirming the unconscious depth of experience, this American reconfiguration welcomes "aesthetic experience back into our philosophical lives" (Henning 5).When embodied meaning supplements cognitive reflection, we come to champion "the sensuous, lived body" as "the primary reality" of qualitative immediacy—a felt aesthetic unity punctuated by "impulsions" arising from an organism's needs (Henning 69). As "a site of adaptive adjustments," Henning continues, "the body is responsive to the brink of coalescence at the point of contact with the world, in which things that are 'outside of it' belong to it" (71). "To move adeptly into aesthetic experience means to be skilled at loosening focal consciousness" so as to cultivate "the essential porousness of the world" (130).With this, the body-mind relation becomes a problem of normative aesthetics, not epistemology. The Cartesian detachment of intellect from nature perpetuated our cultural alienation from our bodies, our environments, and one another (Henning 81–84). With the re-emergence of the body, however, we can begin to acknowledge and heal this trauma.In tapping the significance of qualitative immediacy, of "having" beyond "knowing," Dewey and the Aesthetic Unconscious strives to recover Dewey's remarkable insight into our essential situatedness in the world. This alone establishes its importance. But Henning's book is equally ambitious in suggesting how Dewey's aesthetic understanding can(1). reconfigure the shadowy daemons of Freud's id;(2). replace the myth of American exceptionalism with authentic relationships rooted in pluralist values;(3). rehabilitate the body as an authentic vehicle of expression and communication;(4). vindicate the bold claim that all unified experience is aesthetic; and(5). identify and promote connections forged in shared human experiences.These aims are of inestimable value. I pledge to do whatever I can to defend and advance them. At the outset, however, I feel we must shore up the relationship between two different approaches to thinking about our situatedness in the world: (1) of organic beings existing in a porous world they dynamically interact with, and (2) a phenomenology of experience wherein nonreflective having is an unanalyzed totality from which thought and thing, subject and object, organism and environment, functionally emerge in what Dewey calls the pattern of inquiry. [End Page 78]The general consensus that Dewey failed to reconcile these two approaches—of existence with experience—was dubbed the "deep crack" in Dewey's thought, by Richard Bernstein in 1961. Bernstein laments Dewey's being caught between (1... (shrink)

The book maps out the dynamic relations between the forces at play in politics and the economy in the West through a philosophical analysis of the relations between the concepts of politics and of the economy. It finds that their porous relations inform what it is for humans to live.

The ethics of citation has attracted increased attention in recent discussions of research and publication ethics, fraud and plagiarism. Little attempt has been made, however, to situate specific citation misbehaviors in terms of broader ethical practices and principles. To investigate researchers’ perceptions of citation norms, we surveyed active US researchers receiving federal funding from the National Institutes of Health (NIH), the National Science Foundation (NSF), and the National Endowment for the Humanities (NEH). Participants (_n_ = 257) were asked about citation (...) norms they endorse (norm reports), the behaviors they perceive others to engage in (peer reports), and their own citation behaviors (self-reports). Our analyses showed that while considerable discrepancies exist between norm reports, peer reports and self-reports, respondents’ discipline has no significant effect on these. Participants indicated that their own practices and that of their peers falls short of the norms they endorse, but that their own behavior is much less ethically deficient than that of their peers. An exploratory factor analysis revealed that ethically questionable citation behaviors could be grouped usefully into three categories: strategic citations, neglectful citations, and blind citations. Contrary to our hypothesis, the survey showed that greater experience does not always result in better citation practices. A particularly divisive issue pertained to intentionally citing authors from underrepresented demographic groups for reasons of social justice, but broad support for this practice is lacking, although arts and humanities scholars are slightly more supportive. Most researchers view questionable citation practices as negatively affecting their disciplines. Our findings suggest the need for clearer articulations of the citation norms and improved guidance and training about citations. (shrink)

Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

A fundamental question asked in modal logic is whether a given theory is consistent. But consistent with what? A typical way to address this question identifies a choice of background knowledge axioms (say, S4, D, etc.) and then shows the assumptions codified by the theory in question to be consistent with those background axioms. But determining the specific choice and division of background axioms is, at least sometimes, little more than tradition. This paper introduces generic theories for propositional modal logic (...) to address consistency results in a more robust way. As building blocks for background knowledge, generic theories provide a standard for categorical determinations of consistency. We argue that the results and methods of this paper help to elucidate problems in epistemology and enjoy sufficient scope and power to have purchase on problems bearing on modalities in judgement, inference, and decision making.

Authority arguments generate support for claims by appealing to an agent’s authority status, rather than to reasons independent of it. With few exceptions, the current literature on argument schemes acknowledges two basic authority types. The _epistemic_ type grounds in knowledge, the_ deontic_ type grounds in power. We review how historically earlier scholarship acknowledged an_ attractiveness-based_ and a _majority-based_ authority type as equally basic type. Crossing these with basic speech act types thus yields authority argument sub-schemes. Focusing on the_ epistemic-assertive_ sub-scheme (...) (‘an epistemic authority _A_ _E_ asserts a proposition _P_’), we apply a meta-level approach to specifying critical questions. Results improve the evaluation of this sub-scheme and show how similar improvements are obtainable for other schemes. (shrink)

Inspired by recent progress in multi-agent Reinforcement Learning (RL), in this work we examine the collective intelligent behaviour of theoretical universal agents by introducing a weighted mixture operation. Given a weighted set of agents, their weighted mixture is a new agent whose expected total reward in any environment is the corresponding weighted average of the original agents' expected total rewards in that environment. Thus, if RL agent intelligence is quantified in terms of performance across environments, the weighted mixture's intelligence is (...) the weighted average of the original agents' intelligences. This operation enables various interesting new theorems that shed light on the geometry of RL agent intelligence, namely: results about symmetries, convex agent-sets, and local extrema. We also show that any RL agent intelligence measure based on average performance across environments, subject to certain weak technical conditions, is identical (up to a constant factor) to performance within a single environment dependent on said intelligence measure.
