The affective sciences are essential to research regarding sustainable transition towards renewable energy. We focus on important questions that should be addressed by affective science in relation to the siting of large-scale renewable energy projects like wind and solar. Considering the recent acceleration of the transition, a more holistic understanding of negative and positive emotional responses to energy development will be essential. This is particularly important as the least controversial sites begin to dwindle in number. We break this commentary down (...) into four primary question categories for future research. These are the causal relationships between emotional elicitations and their sources, dual processing through cognitive and affective response, affect and its relationship with place, and how all of these elements change over time.

Author Jeremy Waldron has thoroughly revised thirteen of his most recent essays in order to offer a comprehensive critique of the idea of the judicial review of legislation. He argues that a belief in rights is not the same as a commitment to a Bill of Rights. This book presents legislation by a representative assembly as a form of law making which is especially apt for a society whose members disagree with one another about fundamental issues of principle.

Science is remarkably reliable. It puts people on the moon, performs laser eye surgery, tells us about ancient civilisations and species, and predicts the future of our climate. What underwrites this reliability? This book argues that the standard answers—the scientific method, rigour, and objectivity—are insufficient for the job. Here we propose a new model of science that places its products front and centre. This is the ‘Tangle of Science’. In this book we show how any reliable piece of science is (...) underpinned by a vast, diverse, and thick network of other scientific products. In doing so we bring back into focus areas of science that have been long neglected, emphasising how every product, from the screws that hold the space shuttle together to ways of measuring the consumer price index to Einstein’s theory of general relativity, work together to support results we can trust.

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

We argue against the disquotational meaning schema—‘φ’ means that φ—and suggest that rejecting it is the key to resolving further intensional paradoxes about the limits of thought.

This chapter offers an opinionated introduction to higher-order formal languages with an eye towards their applications in metaphysics. A simply relationally typed higher-order language is introduced in four stages: starting with first-order logic, adding first-order predicate abstraction, generalizing to higher-order predicate abstraction, and finally adding higher-order quantification. It is argued that both β-conversion and Universal Instantiation are valid on the intended interpretation of this language. Given these two principles, it is then shown how we can use pure higher-order logic to (...) ask, and begin to answer, metaphysical questions with non-trivial implications. In particular, while we must reject the popular idea that structural differences between sentences correspond to parallel distinctions in the logical structure of extra-linguistic reality, it may still be possible to give a purely logical characterization of objectual aboutness and related notions.

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question remains controversial (...) in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

This volume collects Jeremy Waldron's challenging and influential work on the moral, political and legal issues surrounding the response to terrorism since 9/11. The volume will be essential reading for all those engaged with contemporary politics and security law, and the continuing struggle for an ethical response to terrorism.

In 1837, Dirichlet proved that there are infinitely many primes in any arithmetic progression in which the terms do not all share a common factor. Modern presentations of the proof are explicitly higher-order, in that they involve quantifying over and summing over Dirichlet characters, which are certain types of functions. The notion of a character is only implicit in Dirichlet’s original proof, and the subsequent history shows a very gradual transition to the modern mode of presentation. In this essay, we (...) describe an approach to the philosophy of mathematics in which it is an important task to understand the roles of our ontological posits and assess the extent to which they enable us to achieve our mathematical goals. We use the history of Dirichlet’s theorem to understand some of the reasons that functions are treated as ordinary objects in contemporary mathematics, as well as some of the reasons one might want to resist such treatment. We also use these considerations to illuminate the formal treatment of functions and objects in Frege’s logical foundation, and we argue that his philosophical and logical decisions were influenced by many of the same factors.

Most people who defend physician-assisted death (PAD) endorse the Joint View, which holds that two conditions—autonomy and welfare—must be satisfied for PAD to be justified. In this paper, we defend an Autonomy Only view. We argue that the welfare condition is either otiose on the most plausible account of the autonomy condition, or else is implausibly restrictive, particularly once we account for the broad range of reasons patients cite for desiring PAD, such as “tired of life” cases. Moreover, many of (...) the common objections to an Autonomy Only view fail once we understand the extent of the autonomy condition’s requirements—in particular, the importance of one’s values for autonomous choices. If our view is correct, then the scope of permissible PAD is broader than is currently accepted in both the philosophical literature and the law, and therefore poses an important challenge to this widely accepted view on justified PAD.

Self-criticism is a trait associated with increased psychopathology, but self-criticism is also a personality state reflecting an action that people do in moments of time. In the current study, we explored factors associated with heightened self-criticism in daily life. Participants (N = 197) received five random prompts per day for one week on their mobile phones, where they reported their current affect (negative and positive affect), willpower self-efficacy, distress intolerance, degree of support and criticism from others, current context (location, activity, (...) hunger, tiredness) and momentary self-criticism. We first demonstrated that self-criticism varies over time and across contexts, and is associated with heightened trait self-criticism. Then, using multilevel modelling, we explored the contextual factors associated with greater self-criticism. We found that self-criticism was higher when people were at home, and more tired. We also found higher self-criticism to be associated with greater negative and lower positive affect, greater distress intolerance, lower willpower and greater perceived criticism from others. In addition, self-criticism predicted subsequent distress intolerance, willpower and positive affect in lagged analyses. This study provides evidence that both environmental and psychological factors are associated with the dynamics of self-critical thoughts. (shrink)

The Negation Problem states that expressivism has insufficient structure to account for the various ways in which a moral sentence can be negated. We argue that the Negation Problem does not arise for expressivist accounts of all normative language but arises only for the specific examples on which expressivists usually focus. In support of this claim, we argue for the following three theses: 1) a problem that is structurally identical to the Negation Problem arises in non-normative cases, and this problem (...) is solved once the hidden quantificational structure involved in such cases is uncovered; 2) the terms ‘required’, ‘permissible’, and ‘forbidden’ can also be analyzed in terms of hidden quantificational structure, and the Negation Problem disappears once this hidden structure is uncovered; 3) the Negation Problem does not arise for normative language that has no hidden quantificational structure. We conclude that the Negation Problem is not really a problem about expressivism at all but is rather a feature of the quantificational structure of the required, permitted, and forbidden. (shrink)

We review three broadly geometrodynamical---and in part, Machian or relational---projects, from the perspective of spacetime functionalism. We show how all three are examples of functionalist reduction of the type that was advocated by D. Lewis, and nowadays goes by the label `the Canberra Plan’. The projects are: the recovery of geometrodynamics by Hojman et al. ; the programme of Schuller and collaborators to deduce a metric from the physics of matter fields; the deduction of the ADM Hamiltonian by Gomes and (...) Shyam. We end by drawing a positive corollary about shape dynamics: namely, it has a good rationale for the Hamiltonian it postulates. (shrink)

Neo-Fregean logicists claim that Hume’s Principle (HP) may be taken as an implicit definition of cardinal number, true simply by fiat. A long-standing problem for neo-Fregean logicism is that HP is not deductively conservative over pure axiomatic second-order logic. This seems to preclude HP from being true by fiat. In this paper, we study Richard Kimberly Heck’s Two-Sorted Frege Arithmetic (2FA), a variation on HP which has been thought to be deductively conservative over second-order logic. We show that it isn’t. (...) In fact, 2FA is not conservative over n-th order logic, for all $n \geq 2$. It follows that in the usual one-sorted setting, HP is not deductively Field-conservative over second- or higher-order logic. (shrink)

This book offers a distinctive treatment of Hayek's ideas as a "research program". It presents a detailed account of aspects of Hayek's intellectual development and of problems that arise within his work, and then offers some broad suggestions as to ways in which the program initiated in his work might be developed further. The book discusses how Popper and Lakatos' ideas about "research programs" might be applied within political theory. There then follows a distinctive presentation of Hayek's intellectual development up (...) to The Road to Serfdom, together with critical engagement with his later ideas. The discussion draws on a full range of his writings, makes use of some neglected earlier work on social theory and law, and also draws on archival material. This book should appeal to anyone with an interest in Hayek's work, as well as to those with a concern for twentieth century intellectual history. (shrink)

Karl Popper was one of the most influential philosophers of the twentieth century. His criticism of induction and his falsifiability criterion of demarcation between science and non-science were major contributions to the philosophy of science. Popper's broader philosophy of critical rationalism comprised a distinctive philosophy of social science and political theory. His critique of historicism and advocacy of the open society marked him out as a significant philosopher of freedom and reason. This book sets out the historical and intellectual contexts (...) in which Popper worked, and offers an overview and diverse criticisms of his central ideas. The volume brings together contributors with expertise on Popper's work, including people personally associated with Popper, specialists on the topics treated, and scholars with special interests in aspects of Popper's work.

Most of us believe that partiality applies in a broad range of relationships. One relationship on which there is much disagreement is co-nationality. Some writers argue that co-national partiality is not justified in certain cases, like killing in war, since killing in defense of co-nationals is intuitively impermissible in other contexts. I argue that this approach overlooks an important structural feature of partiality—namely, that its scope is sometimes restricted. In this essay, I show how some relationships that generate reasons of (...) partiality are restricted in scope—that is, they generate reasons within particular contexts or with respect to particular goods. I then argue that co-national partiality is scope restricted. I then show how this fact helps proponents of co-national partiality overcome the aforementioned objection to its application in cases like war. (shrink)

Purpose Telemedicine has been advancing for decades and is more indispensable than ever in this unprecedented time of the COVID-19 pandemic. As shown, eHealth appears to be effective for routine management of chronic conditions that require extensive and repeated interactions with healthcare professionals, as well as the monitoring of symptoms and diagnostics. Yet much needs to be done to alleviate digital inequalities that stand in the way of making the benefits of eHealth accessible to all. The purpose of this paper (...) is to explore the recent shift in healthcare delivery in response to the COVID-19 pandemic towards telemedicine in healthcare delivery and show how this rapid shift is leaving behind those without digital resources and exacerbating inequalities along many axes. Design/methodology/approach Because the digitally disadvantaged are less likely to use eHealth services, they bear greater risks during the pandemic to meet ongoing medical care needs. This holds true for both medical conditions necessitating lifelong care and conditions of particular urgency such as pregnancy. For this reason, the authors examine two case studies that exemplify the implications of differential access to eHealth: the case of chronic care diseases such as diabetes requiring ongoing care and the case of time-sensitive health conditions such as pregnancy that may be compromised by gaps in continuous care. Findings Not only are the digitally disadvantaged more likely to belong to populations experiencing greater risk – including age and economic class – but they are less likely to use eHealth services and thereby bear greater risks during the pandemic to meet ongoing medical care needs during the pandemic. Social implications At the time of writing, almost 20% of Americans have been unable to obtain medical prescriptions or needed medical care unrelated to the virus. In light of the potential of telemedicine, this does not need to be the case. These social inequalities take on particular significance in light of the COVID-19 pandemic. Originality/value In light of the COVID-19 virus, ongoing medical care requires exposure to risks that can be successfully managed by digital communications and eHealth advances. However, the benefits of eHealth are far less likely to accrue to the digitally disadvantaged. (shrink)

In this contribution in honour of Paul Busch, we criticise the claims of many expositions that the time-energy uncertainty principle allows both a violation of energy conservation and particle creation, provided that this happens for a sufficiently short time. But we agree that there are grains of truth in these claims: which we make precise and justify using perturbation theory.

A critical appraisal of Chiara Bottici’s influential work on imaginal politics, this collection uses this rich theoretical framework for incisive analysis, within critical theory and political philosophy, psychoanalysis and sociology.

Depending on our mode of reasoning—moral, prudential, instrumental, empirical, dialectical, and so on—we may come to vastly different conclusions on the nature of death and the appropriate orientation toward matters such as euthanasia or procuring organs from brain-dead patients. These differing orientations have resulted in some of the most enduring conflicts in biomedical decision-making with roots in the earliest strands of philosophical discourse. Through continually grappling with questions over matters of death, we continually step closer to clarity, even if certainty (...) on these matters remains necessarily as elusive as death itself.

This volume brings together a selection of Rosalind Hursthouse’s essays on Aristotle, virtue ethics, and social philosophy. These articles—many of which are published in more obscure venues—provide valuable context and clarification for much of her more famous work on virtue ethics while drawing attention to new avenues of philosophical investigation Hursthouse pursued. Important contributions include articles on the development of virtue in children, what the Aristotelian practically wise person knows, how virtue ethicists can inform discussions about environmental and animal ethics, (...) what the starting point for virtue politics should be in a contemporary political context, and how human nature and ethical naturalism could provide the foundation for a virtue ethical system.

Hylomorphism is the theory according to which the entities within a specified domain are best understood as composed of both matter and form. Contemporary discussions of hylomorphism have found philosophers revisiting classic points of contention concerning the theory’s scope, application, and utility, but it has also led philosophers to carefully reconsider how best to understand hylomorphism’s most basic claims. In this introduction, I begin by providing a brief overview of some of these main points of discussion in the contemporary literature (...) on hylomorphism and some of the main hylomorphic views currently on offer. After that, I provide an overview of some of the main topics discussed in this special issue, offering a brief summary of each contribution. (shrink)

The first part of this paper surveys the current literature in the history of nineteenth-century mathematics in order to show that the question “Did the increasing abstraction of mathematics lead to a sense of anxiety?” is a new and valid question. I argue that the mathematics of the nineteenth century is marked by a growing appreciation of error leading to a note of anxiety, hesitant at first but persistent by 1900. This mounting disquiet about so many aspects of mathematics after (...) 1850 is seldom discussed. The second part explores the issue of anxiety in mathematical life through an interesting account of an address made by a mathematician in 1911, Oscar Perron. The third and final part ventures some conclusions about the value of anxiety as a question for historians of mathematics to pursue. (shrink)

Despite a significant amount of literature debating the efficiency of high-risk pools in health insurance, dramatically less has been written about their normative implications. The present article takes the route less traveled by setting aside the question of efficiency to argue that the use of high-risk pools creates some serious normative concerns. The article explores these concerns by dividing them on two fronts. First, as regards the social-recognitional status of those who are forced into the high-risk pool. Second, as regards (...) a general concern of distributive justice, namely fairness in access to resources. The author argues that regardless of the veracity of arguments which laud the efficiency of high-risk pools, their use in health insurance is unjust because of the herein explained implications for social recognition and distributive justice.

Introduction, by C.K. Ogden.--The theory of fictions, by Jeremy Bentham.

We argue that individual and institutional caregivers have a defeasible moral duty to provide dependent children with plant-based diets and related education. Notably, our three arguments for this claim do not presuppose any general duty of veganism. Instead, they are grounded in widely shared intuitions about children’s interests and caregivers’ responsibilities, as well as recent empirical research relevant to children’s moral development, autonomy development, and physical health. Together, these arguments constitute a strong cumulative case against inculcating in children the dietary (...) practice of regularly eating meat (and other animal products)—a practice we call “carnism.”.

Workplace ethics perceptions drive ethical behaviors, but our understanding of how context shapes the nature of this relationship is limited. Consequently, this article uses contingency theory to explore how perceptions of ethical priorities in the workplace—ethical work climate (EWC)—are differentially associated with ethical behavior based on the broader context. Specifically, we meta-analytically test theoretically relevant cultural values (i.e., collectivism, power distance) and work context factors (i.e., consequence of errors, job autonomy) as moderators of the connection between EWC perceptions and ethical (...) behavior. Our findings reveal that while higher power-distance societal contexts strengthen the connection between EWC perceptions and ethical behavior, work contexts with higher autonomy _weaken_ the connection. We found mixed support for collectivism as a contextual moderator, with results supporting theoretical expectations with one cultural conceptualization but not another. Contrary to expectations, the consequences of errors in work contexts did not moderate the association between EWC perceptions and ethical behavior. Taken together, this meta-analytic investigation highlights the meaningful role of the broader organizational context as a potential boundary condition for the influence of EWC perceptions on ethical behavior.

In this exciting and challenging account of the development and sustainability of the liberal democratic state, Ajume H. Wingo offers a completely new perspective from that provided by political theorists. Such theorists will typically argue for the basic values of liberal democracies by rationally justifying them. This book argues that it is non-rational factors - rhetoric, symbols, traditions - that more often than not provide the real source of motivation. Drawing from both historical and philosophical sources Ajume H. Wingo demonstrates (...) that these 'veils', as he calls them, can play an essential role in a thriving, stable liberal democratic state. This theory of veil politics furnishes a conceptual framework within which we can reassess the role of aesthetics in politics, the nature and function of political myths in liberal democracies, and the value of civic education.

These remarks consider Andrew Fiala’s Tyranny from Trump to Plato in the context of political apathy and climate pessimism. First, I raise the issue of whether or not some form of tyranny might be necessary in dealing with the crisis of climate change.

Spatial Big Data—be this natively geocoded content, geographical metadata, or data that itself refers to spaces and places—has become a pervasive presence in the spaces and practices of everyday life. Beyond preoccupations with “the geotag” and with mapping geocoded social media content, this special theme explores what it means to encounter and experience spatial Big Data as a quotidian phenomenon that is both spatial, characterized by and enacting of material spatialities, and spatializing, configuring relations between subjects, objects, and spaces in (...) new and unprecedented ways.

In The Crane's Walk, Jeremy Barris seeks to show that we can conceive and live with a pluralism of standpoints with conflicting standards for truth--with the truth of each being entirely unaffected by the truth of the others. He argues that Plato's work expresses this kind of pluralism, and that this pluralism is important in its own right, whether or not we agree about what Plato's standpoint is.The longest tradition of Plato scholarship identifies crucial faults in Plato's theory of (...) Ideas. Barris argues that Plato deliberately displayed those faults, because he wanted to demonstrate that basic kinds of error or illogic have dimensions that are crucial to the establishing of truth. These dimensions legitimate a paradoxical coordination of logically incompatible conceptions of truth. Connecting this idea with emerging currents of Plato scholarship, he emphasizes, in addition to the dialogues' arguments, the importance of their nonargumentative features, including drama, myths, fictions, anecdotes, and humor. These unanalyzed nonargumentative features function rigorously, as a lever with which to examine the enterprise of rational argument itself, without presupposing its standards or illegitimately assimilating any position to the standards of another.Today, communities are torn apart by conflicts within and between a host of different pluralist and absolutist commitments. The possibility developed in this book-a coordination of absolute and relative truth that allows an understanding of some relativist and some absolutist positions as being fully legitimate and as capable of existing in a relation to their opposites-may contribute to perspectives for resolving these conflicts.

This is the first Italian translation of Bentham’s “Deontology”. The translation goes with a rather extended apparatus meant to provide the reader with some information on Bentham’s ethical theory's own context. Some room is made for so-called forerunners of Utilitarianism, from the consequentialist-voluntarist theology of Leibniz, Malebranche, John Gay, Thomas Brown and William Paley to Locke and Hartley's incompatible associationist theories. After the theoretical context, also the real-world context is documented, from Bentham’s campaigns against the oppression of women and cruelty (...) to animals to his projects of political reform. Another section illustrates the ideas of Bentham's followers as well as the objections raised by nineteenth- and twentieth-century critics of utilitarianism. -/- Table of contents I.

The later thought of Karl Popper—notably, his ideas about traditions and his “modified essentialism” in the philosophy of natural science— should lead to revisions in the political philosophy set out in The Open Society and Its Enemies. The structural approach allowed for by Popper's modified essentialism, and the delicate nature of traditions, buttress certain issues raised by Friedrich Hayek that pose serious problems for Popper's social‐democratic approach to politics. Fred Eidlin's review essay on my Political Thought of Karl Popper misses (...) these problems, and in general underestimates the difficulties that unintended consequences pose for any non‐utopian theory of politics. Thus, Eidlin uncritically cites Popper's abstract political recognition of unintended consequences and his idealized view of the political process, as if that puts to rest the questions my book asks.

The overall goal of the approach developed in this paper is to estimate the likelihood of a given kinetic kill scenario between hostile spacebased adversaries using the mathematical framework of Complex Conceptual Spaces Single Observation. Conceptual spaces are a cognitive model that provide a method for systematically and automatically mimicking human decision making. For accurate decisions to be made, the fusion of both hard and soft data into a single decision framework is required. This presents several challenges to this data (...) fusion framework. The first is the challenge involved in handling multiple complex terminologies, which is addressed by drawing on a set of Space Domain Ontologies. Another challenge is the complex combinatorics involved when considering all possible feature combinations. This can be mitigated by using integer linear programming optimization that is outlined by the Complex Conceptual Spaces Single Observation mathematical model framework. A third challenge is the complicated physics that is involved in a spacecraft collision that must be addressed to obtain a better understanding of threat assessment. Overcoming these various challenges allows for a quantitative ranking for the potential of a kinetic kill collision across multiple spacecraft pairs. In addition to overcoming these challenges this paper will break down threat assessment into four domains and identify a ranking of threat both for each individual domain and for the four domains combined. Simulation results are shown to verify the developed concepts. (shrink)
