Why do voters seek to change the political landscape or to retain it? System justification theory proposes that a separate system motive to preserve the existing order drives support for the status-quo, and that this motivation operates independently from personal and collective interests. But how does this explanation apply to recent populist shifts in the political order such as Brexit and the emergence of Donald Trump? While the system motive may seem useful in understanding why the usual progressives may want (...) to stick with an established order, it seems insufficient to explain why the more conservative voters would want to upend the establishment. Thus, we compared SJT’s system motive explanation for the system attitudes of voters on both sides of the political divide to an alternative explanation drawn from the newer social identity model of system attitudes. According to SIMSA, the difficulty in explaining the system attitudes of Brexit/Trump and Remain/Clinton voters from SJT’s system motive standpoint can be resolved by focusing instead on the collective interests that both camps seek to satisfy with their votes. We examined these explanations in two studies conducted soon after Brexit and Trump’s election in 2016, with results providing more support for SIMSA than for SJT. (shrink)

Review comment on the first edition "Wheldall asks himself and his readers what has transpired within the field of educational psychology ... and what its relevance actually is for teaching, learning and education. As such it is a 'must read' for all educational psychologists, students of educational psychology, teachers and teacher trainers." Professor Paul Kirschner, Open Universiteit, British Journal of Educational Technology What is the relevance of educational psychology in the twenty first century? In this collection of essays, leading educational (...) psychologists reflect on the seminal developments which have been made in the field over the past twenty five years or so and assess how far we have progressed. Given a broad and personal remit to address a range of issues, the contributors review and critique a variety of topics, including: intelligence; communication; family environments; individual differences; reading; peer learning; classroom behaviour; and higher education. Providing provocative and challenging insights into the state of contemporary educational psychology, the contributors acknowledge throughout the successes and progression in the field, but with a critical edge and a challenge being thrown down to psychologists of education to make study more seriously informed and as a consequence, reformed. Now in its second edition this compelling text for students and researchers is thoroughly updated and includes four new chapters. (shrink)

Thick terms and concepts, such as honesty and cruelty, are at the heart of a variety of debates in philosophy of language and metaethics. Central to these debates is the question of how the descriptive and evaluative components of thick concepts are related and whether they can be separated from each other. So far, no empirical data on how thick terms are used in ordinary language has been collected to inform these debates. In this paper, we present the first empirical (...) study, designed to investigate whether the evaluative component of thick concepts is communicated as part of the semantic meaning or by means of conversational implicatures. While neither the semantic nor the pragmatic view can fully account for the use of thick terms in ordinary language, our results do favour the semanticist interpretation: the evaluation of a thick concept is only slightly easier to cancel than semantically entailed content. We further discovered a polarity effect, demonstrating that how easily an evaluation can be cancelled depends on whether the thick term is of positive or negative polarity. (shrink)

The role of values in scientific research has become an important topic of discussion in both scholarly and popular debates. Pundits across the political spectrum worry that research on topics like climate change, evolutionary theory, vaccine safety, and genetically modified foods has become overly politicized. At the same time, it is clear that values play an important role in science by limiting unethical forms of research and by deciding what areas of research have the greatest relevance for society. Deciding how (...) to distinguish legitimate and illegitimate influences of values in scientific research is a matter of vital importance.Recently, philosophers of science have written a great deal on this topic, but most of their work has been directed toward a scholarly audience. This book makes the contemporary philosophical literature on science and values accessible to a wide readership. It examines case studies from a variety of research areas, including climate science, anthropology, chemical risk assessment, ecology, neurobiology, biomedical research, and agriculture. These cases show that values have necessary roles to play in identifying research topics, choosing research questions, determining the aims of inquiry, responding to uncertainty, and deciding how to communicate information. Kevin Elliott focuses not just on describing roles for values but also on determining when their influences are actually appropriate. He emphasizes several conditions for incorporating values in a legitimate fashion, and highlights multiple strategies for fostering engagement between stakeholders so that value influences can be subjected to careful and critical scrutiny.

The wide reflective equilibrium (WRE) is considered the most important method of ethical justification and is intensively discussed in the scientific community. However, it is unclear to what extent it is actually applied in the ethical literature. The objective of this paper is to fill this gap by providing a critical overview of its explicit applications. Explicit application refers to studies that, following Daniels’ definition, contain three levels, name their elements, and provide a connection between the levels. Philosophers Index, ProQuest, (...) PubMed, Web of Science, and Scopus were searched for studies that explicitly used the WRE method and were written in German or English. All topics, disciplines, and publication forms were considered. Nineteen studies were found in which the WRE was applied 23 times. In the 23 applications, 50 equilibria were discussed, and 19 times it was reported that an equilibrium state was reached. The authors applied the WRE in various disciplines, for different purposes, and to diverse topics. The applications themselves differed considerably regarding the application procedure and the scope. Differences can be seen in particular with regard to the presentation of the adjustment process and the WRE criteria used. The results indicate that the WRE can be successfully applied, but the number of explicit applications is still very low. Further research is needed to develop the WRE into an established method of justification. In particular, standards are needed for adjustment and for WRE criteria. (shrink)

In _Marx at the Margins_, Kevin Anderson uncovers a variety of extensive but neglected texts by the well-known political economist which cast what we thought we knew about his work in a startlingly different light. Analyzing a variety of Marx’s writings, including journalistic work written for the _New York Tribune_, Anderson presents us with a Marx quite at odds with our conventional interpretations. Rather than providing us with an account of Marx as an exclusively class-based thinker, Anderson here offers (...) a portrait of Marx for the twenty-first century: a global theorist whose social critique was sensitive to the varieties of human social and historical development, including not just class, but nationalism, race, and ethnicity, as well. _Marx at the Margins _ultimately argues that alongside his overarching critique of capital, Marx created a theory of history that was multi-layered and not easily reduced to a single model of development or revolution. Through highly-informed readings on work ranging from Marx’s unpublished 1879–82 notebooks to his passionate writings about the antislavery cause in the United States, this volume delivers a groundbreaking and canon-changing vision of Karl Marx that is sure to provoke lively debate in Marxist scholarship and beyond.

There is growing interest in understanding and eliciting division of labor within groups of scientists. This paper illustrates the need for this division of labor through a historical example, and a formal model is presented to better analyze situations of this type. Analysis of this model reveals that a division of labor can be maintained in two different ways: by limiting information or by endowing the scientists with extreme beliefs. If both features are present however, cognitive diversity is maintained indefinitely, (...) and as a result agents fail to converge to the truth. Beyond the mechanisms for creating diversity suggested here, this shows that the real epistemic goal is not diversity but transient diversity. (shrink)

Provides an accessible and scholarly introduction to the core ideas of the existentialist tradition. Kevin Aho draws on a wide range of existentialist thinkers in chapters centering on the key themes of freedom, being-in-the-world, alienation, nihilism, anxiety and authenticity. He also addresses important but often overlooked issues in the canon of existentialism, with discussions devoted to the role of embodiment, the movement's contribution to ethics, politics, and environmental and comparative philosophies, as well as its influence on contemporary psychiatry and (...) psychotherapy. The enduring relevance of existentialism is shown by applying existentialist ideas to contemporary philosophical discussions of interest to a wide audience. The book covers secular thinkers such as Heidegger, Merleau-Ponty, Nietzsche, Sartre, Camus, and Beauvoir as well as religious authors, such as Buber, Dostoevsky, Marcel, and Kierkegaard"--Back cover.

Perception involves the processing of content or information about the world. In what form is this content represented? I argue that perception is widely compositional. The perceptual system represents many stimulus features (including shape, orientation, and motion) in terms of combinations of other features (such as shape parts, slant and tilt, common and residual motion vectors). But compositionality can take a variety of forms. The ways in which perceptual representations compose are markedly different from the ways in which sentences or (...) thoughts are thought to be composed. I suggest that the thesis that perception is compositional is not itself a concrete hypothesis with specific predictions; rather it affords a productive framework for developing and evaluating specific empirical hypotheses about the form and content of perceptual representations. The question is not just whether perception is compositional, but how. Answering this latter question can provide fundamental insights into perception. (shrink)

This essay explores the unique temporal experience in anxiety. Drawing on first-person accounts as well as examples from literature, I attempt to show how anxiety not only disrupts our physiological and cognitive timing but also disturbs the embodied rhythms of everyday social life. The primary goal, however, is to articulate the extent to which human existence itself is a temporally structured event and to identity the ways that anxiety disrupts this structure. Using Martin Heidegger’s account of human existence as a (...) point of departure, I show how the mood of anxiety has the power to alter our self-interpretations by closing down or constricting our experience of the future. I argue that a constricted future impedes our ability ‘to be’ because it closes off the range of projective meanings that we would ordinarily draw on to create or fashion our identities. (shrink)

This book brings together eleven case studies of inductive risk-the chance that scientific inference is incorrect-that range over a wide variety of scientific contexts and fields. The chapters are designed to illustrate the pervasiveness of inductive risk, assist scientists and policymakers in responding to it, and productively move theoretical discussions of the topic forward.

Both scientists and philosophers of science have recently emphasized the importance of promoting transparency in science. For scientists, transparency is a way to promote reproducibility, progress, and trust in research. For philosophers of science, transparency can help address the value-ladenness of scientific research in a responsible way. Nevertheless, the concept of transparency is a complex one. Scientists can be transparent about many different things, for many different reasons, on behalf of many different stakeholders. This paper proposes a taxonomy that clarifies (...) the major dimensions along which approaches to transparency can vary. By doing so, it provides several insights that philosophers and other science studies scholars can pursue. In particular, it helps address common objections to pursuing transparency in science, it clarifies major forms of transparency, and it suggests avenues for further research on this topic. (shrink)

According to Phenomenal Conservatism (PC), if a subject S has an appearance that P, in the absence of defeaters, S has justification for believing P by virtue of her appearance's inherent justifying power. McCain and Moretti (2021) have argued that PC is affected by the problem of reflective awareness: if S becomes reflectively aware of an appearance, the appearance loses its inherent justifying power. This limits the explanatory power of PC and reduces its antisceptical bite. This paper provides a novel (...) argument to the same conclusion and contends that it does not apply to Phenomenal Explanationism, the appearance-based account of justification alternative to PC defended by McCain and Moretti (2021).

Increasingly, epistemologists are becoming interested in social structures and their effect on epistemic enterprises, but little attention has been paid to the proper distribution of experimental results among scientists. This paper will analyze a model first suggested by two economists, which nicely captures one type of learning situation faced by scientists. The results of a computer simulation study of this model provide two interesting conclusions. First, in some contexts, a community of scientists is, as a whole, more reliable when its (...) members are less aware of their colleagues' experimental results. Second, there is a robust tradeoff between the reliability of a community and the speed with which it reaches a correct conclusion. ‡The author would like to thank Brian Skyrms, Kyle Stanford, Jeffrey Barrett, Bruce Glymour, and the participants in the Social Dynamics Seminar at University of California–Irvine for their helpful comments.

A keen athlete in his late forties, philosophy professor Kevin Aho hadn't given much thought to his own mortality, until he suffered a sudden heart attack that left him fighting for his life. Confronted with death for the first time, he realized that the things he thought gave his life meaning, such as his independence or his ability to plan his own future, were in tatters. Aho turned to those thinkers who have reflected deeply on the meaning of life (...) and the anxiety of living when every heartbeat might be your last: the existentialists. Armed with insights from the likes of Kierkegaard, Heidegger, Nietzsche, and de Beauvoir, he found new meaning and comfort in a view of life that strives for authenticity and accepts aging and death as part of what makes life worthwhile. Existentialism asks us to face the frailty of our existence and to live with a sense of urgency and gratitude toward its manifold beauties. It is only then that we can be released from patterns of self-deception and begin to appreciate what truly matters in our fleeting, precious lives. (shrink)

You have higher-order uncertainty iff you are uncertain of what opinions you should have. I defend three claims about it. First, the higher-order evidence debate can be helpfully reframed in terms of higher-order uncertainty. The central question becomes how your first- and higher-order opinions should relate—a precise question that can be embedded within a general, tractable framework. Second, this question is nontrivial. Rational higher-order uncertainty is pervasive, and lies at the foundations of the epistemology of disagreement. Third, the answer is (...) not obvious. The Enkratic Intuition---that your first-order opinions must “line up” with your higher-order opinions---is incorrect; epistemic akrasia can be rational. If all this is right, then it leaves us without answers---but with a clear picture of the question, and a fruitful strategy for pursuing it. (shrink)

Theories of scientific rationality typically pertain to belief. In this paper, the author argues that we should expand our focus to include motivations as well as belief. An economic model is used to evaluate whether science is best served by scientists motivated only by truth, only by credit, or by both truth and credit. In many, but not all, situations, scientists motivated by both truth and credit should be judged as the most rational scientists.

Work on a computer program called SMILE + IBP (SMart Index Learner Plus Issue-Based Prediction) bridges case-based reasoning and extracting information from texts. The program addresses a technologically challenging task that is also very relevant from a legal viewpoint: to extract information from textual descriptions of the facts of decided cases and apply that information to predict the outcomes of new cases. The program attempts to automatically classify textual descriptions of the facts of legal problems in terms of Factors, a (...) set of classification concepts that capture stereotypical fact patterns that effect the strength of a legal claim, here trade secret misappropriation. Using these classifications, the program can evaluate and explain predictions about a problem’s outcome given a database of previously classified cases. This paper provides an extended example illustrating both functions, prediction by IBP and text classification by SMILE, and reports empirical evaluations of each. While IBP’s results are quite strong, and SMILE’s much weaker, SMILE + IBP still has some success predicting and explaining the outcomes of case scenarios input as texts. It marks the first time to our knowledge that a program can reason automatically about legal case texts. (shrink)

This Element introduces the philosophical literature on values in science by examining four questions: How do values influence science? Should we actively incorporate values in science? How can we manage values in science responsibly? What are some next steps for those who want to help promote responsible roles for values in science? It explores arguments for and against the “value-free ideal” for science and concludes that it should be rejected. Nonetheless, this does not mean that value influences are always acceptable. (...) The Element explores a range of strategies for distinguishing between appropriate and inappropriate value influences. It concludes by proposing an approach for managing values in science that relies on justifying, prioritising, and implementing norms for scientific research practices and institutions. (shrink)

The role of research ethics consultants in biomedical research has increased to the point that they have an advisory capacity at all research institutes. For such professionals, we have established an educational system, which includes teaching materials, training methods, and nationwide educational workshops. These workshops have served to examine the developed system’s usefulness and to provide realistic training for consultant candidates. In addition, we have used the current workshop to encourage clinical research investigators to participate. Subsequently, we examined its usefulness (...) as an opportunity to provide exposure to research ethics. In October 2019, we held a 1-day pilot workshop in Tokushima, Japan, which included a basic lecture in research ethics. During the lecture, two sets of materials were used for case discussion: case 1, covering issues related to a clinical trial, and case 2, covering issues related to human biological specimens. At the end of the workshop, a 30-item self-reporting anonymous questionnaire was provided. Of the 13 total participants, 9 were clinical research investigators and related personnel, while 6 had no direct intention to act as consultants. Respondents indicated that case 2 was more difficult than case 1. However, both cases were generally accepted as educational materials; thus, satisfaction was expressed in relation to both. As the evaluations of the cases were generally positive, we will further examine the usefulness of participation in the workshop in the cultivation of research ethics in the investigator community.

Sosa, Pritchard, and Vogel have all argued that there are cases in which one knows something inductively but does not believe it sensitively, and that sensitivity therefore cannot be necessary for knowledge. I defend sensitivity by showing that inductive knowledge is sensitive.

In recent papers and a book, Heather Douglas has expanded on the well-known argument from inductive risk, thereby launching an influential contemporary critique of the value-free ideal for science. This paper distills Douglas’s critique into four major claims. The first three claims provide a significant challenge to the value-free ideal for science. However, the fourth claim, which delineates her positive proposal to regulate values in science by distinguishing direct and indirect roles for values, is ambiguous between two interpretations, and both (...) have weaknesses. Fortunately, two elements of Douglas’s work that have previously received much less emphasis provide resources for developing a more promising approach for regulating values in science. (shrink)

In the eyes of many, liberalism requires the aggressive secularization of social institutions, especially public media and public schools. The unfortunate result is that many Americans have become alienated from the liberal tradition because they believe it threatens their most sacred forms of life. This was not always the case: in American history, the relation between liberalism and religion has often been one of mutual respect and support. In Liberal Politics and Public Faith: Beyond Separation , Kevin Vallier attempts (...) to reestablish mutual respect by developing a liberal political theory that avoids the standard liberal hostility to religious voices in public life. He claims that the dominant form of academic liberalism, public reason liberalism, is far friendlier to religious influences in public life than either its proponents or detractors suppose. The best interpretation of public reason, convergence liberalism, rejects the much-derided "privatization" of religious belief, instead viewing religious contributions to politics as a resource for liberal political institutions. Many books reject privatization, Liberal Politics and Public Faith: Beyond Separation is unique in doing so on liberal grounds. (shrink)

Although many philosophers have employed the distinction between “direct” and “indirect” roles for values in science, I argue that it merits further clarification. The distinction can be formulated in several ways: as a logical point, as a distinction between epistemic attitudes, or as a clarification of different consequences associated with accepting scientific claims. Moreover, it can serve either as part of a normative ideal or as a tool for policing how values influence science. While various formulations of the distinction may (...) contribute to a normative ideal, they have limited effectiveness for regulating how values influence science. (shrink)

Vogel, Sosa, and Huemer have all argued that sensitivity is incompatible with knowing that you do not believe falsely, therefore the sensitivity condition must be false. I show that this objection misses its mark because it fails to take account of the basis of belief. Moreover, if the objection is modified to account for the basis of belief then it collapses into the more familiar objection that sensitivity is incompatible with closure.

This article considers the motivations of teachers to pursue ongoing professional learning. During recent decades, the international policy context has been characterised by high-stakes accountability, but the implications of this agenda for teachers’ motivations toward professional learning remains under-explored. In this mixed methods study, combining a large teacher survey and in-depth teacher interviews, a new and significant concept of ‘instrumental motivation’ is generated to capture how high-stakes performance management policies damage the motivation of teachers to learn professionally. This innovative approach, (...) employing ordinal factor analysis and inductive/deductive hybrid thematic analysis inclusive of self-determination theory, reveals how the ‘instrumental motivation’ of teachers should be constrained and argues for the adoption of alternative motivational strategies to support effective professional learning in schools.

The rise of medically unexplained conditions like fibromyalgia and chronic fatigue syndrome in the United States looks remarkably similar to the explosion of neurasthenia diagnoses in the late nineteenth century. In this paper, I argue the historical connection between neurasthenia and today’s medically unexplained conditions hinges largely on the uncritical acceptance of naturalism in medicine. I show how this cultural acceptance shapes the way in which we interpret and make sense of nervous distress while, at the same time, neglecting the (...) unique social and historical forces that continue to produce it. I draw on the methods of hermeneutic philosophy to expose the limits of naturalism and forward an account of health and illness that acknowledges the extent to which we are always embedded in contexts of meaning that determine how we experience and understand our suffering.

We argue that the analysis of cognitive attitudes should play a central role in developing more sophisticated accounts of the proper roles for values in science.

What is the property of being true like? To answer this question, begin with a Canberra-plan analysis of the concept of truth. That is, assemble the platitudes for the concept of truth, and then investigate which property might satisfy them.

Conceptual engineering is assessing the quality of our concepts, and when they are found defective, offering new and better concepts to replace them for certain purposes.

We can treat these aletheic properties as a guide to the multitude of new aletheic concepts, which are concepts similar to, but distinct from, the concept of truth. Any new aletheic concept or team of concepts might be called on to replace the concept of truth. In particular, the concepts of ascending truth and descending truth are recommended, but the most important point is that we need a full-scale investigation into the space of aletheic properties and new aletheic concepts—that is, we need an Aletheic Principles Project.

There has been relatively little effort to provide a systematic overview of different forms of exploratory experimentation (EE). The present paper examines the growing subdiscipline of nanotoxicology and suggests that it illustrates at least four ways that researchers can engage in EE: searching for regularities; developing new techniques, simulation models, and instrumentation; collecting and analyzing large swaths of data using new experimental strategies (e.g., computer-based simulation and "high-throughput" instrumentation); and structuring an entire disciplinary field around exploratory research agendas. In order (...) to distinguish these and other activities more effectively, the paper proposes a taxonomy that includes three dimensions along which types of EE vary: (1) the aim of the experimental activity, (2) the role of theory in the activity, and (3) the methods or strategies employed for varying experimental parameters.

Experts from wine tasters to radiologists to bird watchers have all undergone perceptual learning-long-term changes in perception that result from practice or experience. Philosophers have been discussing such cases for centuries, from the 14th-century Indian philosopher Vedanta Desika to the 18th-century Scottish philosopher Thomas Reid, and into contemporary times. -/- This book uses recent evidence from psychology and neuroscience to show that perceptual learning is genuinely perceptual, rather than post-perceptual. It also offers a taxonomy for classifying cases in the philosophical (...) literature. In some cases, perceptual learning involves changes in how one attends; in other cases, it involves a learned ability to differentiate two properties, or to perceive two properties as unified. Connolly uses this taxonomy to rethink several domains of perception in terms of perceptual learning, including multisensory perception, color perception, and speech perception. -/- As a whole, the book offers a theory of the function of perceptual learning. Perceptual learning embeds into our quick perceptual systems what would be a slower task were it to be done in a controlled, cognitive manner. A novice wine taster drinking a Cabernet Sauvignon might have to think about its features first and then infer the type of wine, while an expert can identify it immediately. This learned ability to immediately identify the wine enables the expert to think about other things like the vineyard or the vintage of the wine. More generally, perceptual learning serves to free up cognitive resources for other tasks. This book offers a comprehensive empirically-informed account, and explores the nature, scope, and theoretical implications of perceptual learning. (shrink)

In a recent paper, Melchior pursues a novel argumentative strategy against the sensitivity condition. His claim is that sensitivity suffers from a ‘heterogeneity problem:’ although some higher-order beliefs are knowable, other, very similar, higher-order beliefs are insensitive and so not knowable. Similarly, the conclusions of some bootstrapping arguments are insensitive, but others are not. In reply, I show that sensitivity does not treat different higher-order beliefs differently in the way that Melchior states and that while genuine bootstrapping arguments have insensitive (...) conclusions, the cases that Melchior describes as sensitive ‘bootstrapping’ arguments don’t deserve the name, since they are a perfectly good way of getting to know their conclusions.

This paper approaches the problem of testimony from a new direction. Rather than focusing on the epistemic grounds for testimony, it considers the problem from the perspective of an individual who must choose whom to trust from a population of many would-be testifiers. A computer simulation is presented which illustrates that in many plausible situations, those who trust without attempting to judge the reliability of testifiers outperform those who attempt to seek out the more reliable members of the community. In (...) so doing, it presents a novel defense for the credulist position that argues one should trust testimony without considering the underlying reliability of the testifier. (shrink)

He argues further that the discussion included here shows how deeply our understanding of nature, and our understanding of nature sports, influence both our experiences within those sports and our broader experience of the world.

Homo sapiens is entering a vital era in which the human-technology link is an inexorable trend. In this paper a look is taken as to how and why this is coming about and what exactly it means for both the posthuman species Homo technologicus and its originator Homo sapiens. Clearly moral and ethical issues are at stake. Different practical experimentation results that relate to the theme are described and the argument is raised as to why and how this can be (...) regarded as a new species. A picture is taken of the status of cyborgs as it stands today but also how this will change in the near future, as the effects of increased technological power have a more dramatic influence. An important ultimate consideration is whether Homo technologicus will act in the best interests of Homo sapiens or not. This paper concludes that the answer is clear. (shrink)
