Whereas boson coherent states with complex parametrization provide an elegant, and intuitive representation, there is no counterpart for fermions using complex parametrization. However, a complex parametrization provides a valuable way to describe amplitude and phase of a coherent beam. Thus we pose the question of whether a fermionic beam can be described, even approximately, by a complex-parametrized coherent state and define, in a natural way, approximate complex-parametrized fermion coherent states. Then we identify four appealing properties of boson coherent states (eigenstate (...) of annihilation operator, displaced vacuum state, preservation of product states under linear coupling, and factorization of correlators) and show that these approximate complex fermion coherent states fail all four criteria. The inapplicability of complex parametrization supports the use of Grassman algebras as an appropriate alternative. (shrink)

A Benacerraf–Field challenge is an argument intended to show that common realist theories of a given domain are untenable: such theories make it impossible to explain how we’ve arrived at the truth in that domain, and insofar as a theory makes our reliability in a domain inexplicable, we must either reject that theory or give up the relevant beliefs. But there’s no consensus about what would count here as a satisfactory explanation of our reliability. It’s sometimes suggested that giving such (...) an explanation would involve showing that our beliefs meet some modal condition, but realists have claimed that this sort of modal interpretation of the challenge deprives it of any force: since the facts in question are metaphysically necessary and so obtain in all possible worlds, it’s trivially easy, even given realism, to show that our beliefs have the relevant modal features. Here I show that this claim is mistaken—what motivates a modal interpretation of the challenge in the first place also motivates an understanding of the relevant features in terms of epistemic possibilities rather than metaphysical possibilities, and there are indeed epistemically possible worlds where the facts in question don’t obtain.

This article proposes that Horace's Epodes and Ovid's Metamorphoses open with significant acrostics that comprise the first two letters, in some cases forming syllables, of successive lines: IB-AM/IAMB (Epod. 1.1–2) and IN-CO-(H)AS (Met. 1.1–3). Each acrostic, it will be argued, tees up programmatic concerns vital to the work it opens: generic identity and the interrelation of form and content (Epodes), etymology and monumentality (Metamorphoses). Moreover, as befits their placement at the head of collections, both acrostics negotiate the challenge of literary (...) commencement. The introduction reviews recent developments in acrostic studies and discusses important predecessors and parallels for Horace's and Ovid's ‘two-letter’ and syllabic acrostics. Two subsequent sections examine the acrostics singly, and a conclusion compares the dialogues that these acrostics open between author and reader, underscoring the welcome challenge which Ovid's acrostic offers to the prevailing scholarly view that this form of wordplay is a strictly visual affair.

Truth by convention, once thought to be the foundation of a uniquely promising approach to explaining our access to the truth in nonempirical domains, is nowadays widely considered an absurdity. Its fall from grace has been due largely to the influence of an argument that can be sketched as follows: our linguistic conventions have the power to make it the case that a sentence expresses a particular proposition, but they can’t by themselves generate truth; whether a given proposition is true—and (...) so whether the sentence that expresses it is true—is a matter of what the world is like, which means it isn’t a matter of convention alone. The consensus is that this argument is decisive against truth by convention. Strikingly, though, it has rarely been formulated with much precision. Here I provide a new rendering of the argument, one that reveals its structure and makes transparent just what assumptions it requires, and then I assess conventionalists’ prospects for resisting each of those assumptions. I conclude that the consensus is mistaken: contrary to what is almost universally thought, there remains a promising way forward for the conventionalist project. Along the way, I clarify conventionalists’ commitments by thinking about what truth by convention would need to be like in order for conventionalism to do the epistemological work it’s intended to do.

The aesthetics of imperfection emphasises spontaneity, disruption, process and energy over formal perfection and is often ignored by many commentators or seen only in improvisation. This comprehensive collection is the first time imperfection has been explored across all kinds of musical performance, whether improvisation or interpretation of compositions. Covering music, visual art, dance, comedy, architecture and design, it addresses the meaning, experience, and value of improvisation and spontaneous creation across different artistic media. A distinctive feature of the volume is that (...) it brings together contributions from theoreticians and practitioners, presenting a wider range of perspectives on the issues involved. Contributors look at performance and practice across Western and non-Western musical, artistic and craft forms. Composers and non-performing artists offer a perspective on what is 'imperfect' or improvisatory within their work, contributing further dimensions to the discourse. The Aesthetics of Imperfection in Music and the Arts features 39 chapters organised into eight sections and written by a diverse group of scholars and performers. They consider divergent definitions of aesthetics, employing both 18th-century philosophy and more recent socially and historically situated conceptions making this an essential, up-to-date resource for anyone working on either side of the perfection-imperfection debate.

Written across the disciplines of art history, literature, philosophy, sociology, and theology, the ten essays comprising the collection all insist on multidimensional definitions of evil. Taking its title from a moment in Shakespeare's Tempest when Prospero acknowledges his responsibility for Caliban, this collection explores the necessarily ambivalent relationship between humanity and evil. To what extent are a given society's definitions of evil self-serving? Which figures are marginalized in the process of identifying evil? How is humanity itself implicated in the production (...) of evil? Is evil itself something fundamentally human? These questions, indicative of the kinds of issues raised in this collection, seem all the more pressing in light of recent world events. The ten essays were originally presented at the First Global Conference on Perspectives on Evil and Human Wickedness, held in March 2000 in Lady Margaret Hall, Oxford University. (shrink)

India has a long, rich, and diverse tradition of philosophical thought, spanning some two and a half millenia and encompassing several major religious traditions. Now, in this intriguing introduction to Indian philosophy, the diversity of Indian thought is emphasized. It is structured around six schools of thought that have received classic status. Sue Hamilton explores how the traditions have attempted to understand the nature of reality in terms of inner or spiritual quest and introduces distinctively Indian concepts, such as (...) karma and rebirth. She also explains how Indian thinkers have understood issues of reality and knowledge-issues that re also an important part of the Western philosophical tradition. (shrink)

The frame problem refers to the fact that organisms must be able to zero in on relevant aspects of the world and intelligently ignore the vast majority of the world that is irrelevant to their goals. In this paper we aim to point out the connection between two leading frameworks for thinking about how organisms achieve this. Predictive processing is a rapidly growing framework within cognitive science which suggests that organisms assign a high ‘weight’ to relevant aspects of the world, (...) effectively treating relevant aspects of the world as if they are more precise. This assignment of weight is called precision-weighting and is the predictive processing account of how organisms allocate their attention. Relevance Realization is a framework that conceptualizes an organism’s ability to realize relevance as resulting from a dynamical system in which a cognitive agent makes use of opponent processing relationships to zero in on relevant aspects of the world. In this paper we use recent work on the diametric model of autism and psychosis to demonstrate that the tradeoffs inherent to precision-weighting are also inherent to relevance realization. This connection will demonstrate that although these frameworks have a different intellectual background and use a different set of concepts and vocabulary, they are both pointing to the same underlying process. The fact that these different frameworks have converged on such a similar solution to the problem of how organisms realize relevance serves to demonstrate the plausibility of that solution. (shrink)

Drawing on recent advances in evolutionary biology, prominent scholars return to the question posed in a pathbreaking book: how evolution itself evolved.

I argue that Quinean naturalists’ holism-based arguments against analyticity and apriority are more difficult to resist than is generally supposed, for two reasons. First, although opponents of naturalism sometimes dismiss these arguments on the grounds that the holistic premises on which they depend are unacceptably radical, it turns out that the sort of holism required by these arguments is actually quite minimal. And second, although it’s true, as Grice and Strawson pointed out long ago, that these arguments can succeed only (...) if there isn’t any principled criterion for meaning change, such a criterion turns out to be hard to come by. David Chalmers has recently argued that such a criterion must exist, since the norms governing belief revision are subject to obvious exceptions that can be explained only by appeal to meaning change. But this, I argue, is incorrect: if choices about how to use language are themselves rationally assessable, then there are no such exceptions to be explained. To show that this is so, I formulate a new kind of coherence norm that may be useful for reasoning formally about the relationship between meaning and evidence. (shrink)

Every day, new warnings emerge about artificial intelligence rebelling against us. All the while, a more immediate dilemma flies under the radar. Have forces been unleashed that are thrusting humanity down an ill-advised path, one that's increasingly making us behave like simple machines? In this wide-reaching, interdisciplinary book, Brett Frischmann and Evan Selinger examine what's happening to our lives as society embraces big data, predictive analytics, and smart environments. They explain how the goal of designing programmable worlds goes hand (...) in hand with engineering predictable and programmable people. Detailing new frameworks, provocative case studies, and mind-blowing thought experiments, Frischmann and Selinger reveal hidden connections between fitness trackers, electronic contracts, social media platforms, robotic companions, fake news, autonomous cars, and more. This powerful analysis should be read by anyone interested in understanding exactly how technology threatens the future of our society, and what we can do now to build something better. (shrink)

Emotion Review, Volume 14, Issue 3, Page 167-181, July 2022. A growing cadre of influential scholars has converged on a circumscribed definition of empathy as restricted only to feeling the same emotion that one perceives another is feeling. We argue that this restrictive isomorphic matching definition is deeply problematic because it deviates dramatically from traditional conceptualizations of empathy and unmoors the construct from generations of scientific research and clinical practice; insistence on an isomorphic form undercuts much of the functional value (...) of empathy from multiple perspectives of analysis; and combining the opposing concepts of isomorphic matching and self-other awareness implicitly requires motivational content, causing the RIM definition to implicitly require the kind of non-matching emotional content that it explicitly seeks to exclude.

Sensitivity has sometimes been thought to be a highly epistemologically significant property, serving as a proxy for a kind of responsiveness to the facts that ensure that the truth of our beliefs isn’t just a lucky coincidence. But it's an imperfect proxy: there are various well-known cases in which sensitivity-based anti-luck conditions return the wrong verdicts. And as a result of these failures, contemporary theorists often dismiss such conditions out of hand. I show here, though, that a sensitivity-based understanding of (...) epistemic luck can be developed that respects what was attractive about sensitivity-based approaches in the first place but that's immune to these failures.

An authoritative and accessible book by a qualified scientist, showing incredible proof of the mind-body connection. There is no longer any doubt that the way we think affects our bodies: countless scientific studies have shown this to be true. For former pharmaceutical scientist Dr David Hamilton, the testing of new drugs highlighted how profoundly the mind and body are connected. Time and time again, the control group of patients in drug trials improved at similar rates to those who actually (...) received the medicines. Astounded, Dr Hamilton decided to change the direction of his work to explore the relationship between the mind and the body. This bestselling acclaimed book was first published 10 years ago. In it, Dr Hamilton explores the effect of visualization, belief and positive thinking on the body, and shows how using our imagination and mental processes can stimulate our own defences and healing systems to combat disease, pain and illness. In this new edition, Dr Hamilton has added four new chapters to discuss the latest cutting-edge information and extraordinary new techniques. These include using imagery to stimulate the immune system - a method that can benefit cancer patients undergoing conventional treatment - effectively using the mind to speed up rehabilitation from stroke, and powerful visualization strategies to help facilitate recovery from injury and illness.

When epistemologists talk about knowledge, the discussions traditionally include only a small class of other epistemic notions: belief, justification, probability, truth. In this paper, we propose that epistemologists should include an additional epistemic notion into the mix, namely the notion of assuming or taking for granted.

Which rules should guide our reasoning? Human reasoners often use reasoning shortcuts, called heuristics, which function well in some contexts but lack the universality of reasoning rules like deductive implication or inference to the best explanation. Does it follow that human reasoning is hopelessly irrational? I argue: no. Heuristic reasoning often represents human reasoners reaching a local rational maximum, reasoning more accurately than if they try to implement more “ideal” rules of reasoning. I argue this is a genuine rational achievement. (...) Our ideal rational advisors would advise us to reason with heuristic rules, not more complicated ideal rules. I argue we do not need a radical new account of epistemic norms to make sense of the success of heuristic reasoning. (shrink)

The literature contains evidence from some studies of asymmetric patterns of choice cycles in the direction consistent with regret theory, and evidence from other studies of asymmetries in the opposite direction. This article reports an experiment showing that both patterns occur within the same sample of respondents operating in the same experimental environment.

Why can I not appropriately utter ‘It must be raining’ while standing outside in the rain, even though every world consistent with my knowledge is one in which it is raining? The common response to this problem is to hold that epistemic must, in addition to quantifying over epistemic possibilities, carries some additional evidential information concerning the source of one'S evidence. I argue that this is a mistake: epistemic modals are mere quantifiers over epistemic possibilities. My central claim is that (...) the seeming anomaly of the data above arises from a mistaken conception of what a possibility is. Instead of conceiving of possibilities as possible worlds, I argue that we should conceive of possibilities as answers to open questions. (shrink)

This paper describes a pattern of explanation prevalent in the biological sciences that I call a ‘lineage explanation’. The aim of these explanations is to make plausible certain trajectories of change through phenotypic space. They do this by laying out a series of stages, where each stage shows how some mechanism worked, and the differences between each adjacent stage demonstrates how one mechanism, through minor modifications, could be changed into another. These explanations are important, for though it is widely accepted (...) that there is an ‘incremental constraint’ on evolutionary change, in an important class of cases it is difficult to see how to satisfy this constraint. I show that lineage explanations answer important questions about evolutionary change, but do so by demonstrating differences between individuals rather than invoking population processes, such as natural selection.1.

It is commonly held that the context with respect to which an indexical is interpreted is determined independently of the interpretation of the indexical. This view, which I call Context Realism, has explanatory significance: it is because the context is what it is that an indexical refers to what it does.

I then develop an alternative that I call Context Constructivism, according to which indexicals are defined not in terms of (...) features of utterance situations, but rather in terms of roles that objects could play.

While research has focused on why certain entrepreneurs elect to create innovative solutions to social problems, very little is known about why some social entrepreneurs choose to scale their solutions while others do not. Research on scaling has generally focused on organizational characteristics often overlooking factors at the individual level that may affect scaling decisions. Drawing on the multidimensional construct of moral intensity, we propose a theoretical model of ethical decision making to explain why a social entrepreneur’s perception of moral (...) intensity of the social problem, coupled with their personal desire for control, can significantly influence scaling decisions. Specifically, we propose that higher levels of perceived moral intensity will positively influence the likelihood of scaling through open as opposed to closed modes in order to achieve greater speed and scope of social impact. However, we also propose this effect will be negatively moderated by a social entrepreneur’s higher levels of desire for control. Our model has implications for research and practice at the interface of ethics and social entrepreneurship. (shrink)

The dual-use issue is often framed as a series of paralyzing ‘dilemmas’ facing the scientific community as well as institutions which support innovation. While this conceptualization of the dual-use issue can be useful in certain contexts its usefulness is more limited when reflecting on the governance and politics of the dual-use issue. Within this paper, key shortcomings of the dilemma framing are outlined. It is argued that many of the issues raised in the most recent debates about ‘dual-use’ bird flu (...) research remain unresolved. This includes questions about the trajectories of certain lines of research, as well as broader trends in the practice and governance of science. This leads to difficult questions about current approaches to the dual-use issue within the US, as well as internationally. (shrink)

Humans’ indigenous microbes strongly influence organ functions in an age‐ and diet‐dependent manner, adding an important dimension to aging biology that remains poorly understood. Although age‐related differences in the gut microbiota composition correlate with age‐related loss of organ function and diseases, including inflammation and frailty, variation exists among the elderly, especially centenarians and people living in areas of extreme longevity. Studies using short‐lived as well as nonsenescent model organisms provide surprising functional insights into factors affecting aging and implicate attenuating effects (...) of microbes as well as a crucial role for certain transcription factors like forkhead box O. The unexpected beneficial effects of microbes on aged animals imply an even more complex interplay between the gut microbiome and the host. The microbiome constitutes the major interface between humans and the environment, is influenced by biosocial stressors and behaviors, and mediates effects on health and aging processes, while being moderated by sex and developmental stages.

After two years of discussions and revisions, the World Anti-Doping Agency (WADA) published the 2021 World Anti-Doping Code on June 16, 2020. Among the most significant additions to this iteration of the Code was the inclusion of new categories of athletes subject to differential treatment by WADA, including the “protected person” category. In this paper, we examine the recent case of figure skater Kamila Valeryevna Valieva, the first athlete given differential treatment due to her being categorized as a “protected person.” (...) We apply a relational justice framework to the case to provide a nuanced, descriptive analysis of the case generally, and the application of the “protected person” category in particular.We first describe details of the athlete, her performances and anti-doping rule violation, and the “protected person” category, to provide context. We then describe and analyze the relations between several institutional actors, principally WADA and the International Court for the Arbitration of Sport (CAS), the athlete and her team, and other figure skating athletes at the Beijing Winter Olympic Games. To do so, we use two concepts of justice, conservative and ideal, and their component parts, entitlement, desert, and need.Our description and analyses demonstrate that (1) WADA’s notions of justice are essentially conservative, while CAS acted toward more ideal notions, creating a fundamental disagreement in what was owed and to whom. We show (2) that CAS’ decision may have nonetheless caused harm to the athlete, raising questions about the efficacy and capability of the “protected person” category. Finally, (3) our analyses show the influence that notions of justice necessarily have these actors shape each other, thus change the sporting institutions and activities themselves. (shrink)

When government actors seek to restrict the sale of hazardous substances, industry actors tend to intervene, deploying coordinated strategies aimed at delaying, preventing or weakening attempts to regulate their products. In many cases, this has involved deliberate efforts to obfuscate science, mislead the public and manipulate political actors in order to ensure desired policy outcomes. Strategies of regulatory obstructionism have resulted in the prolonged dispersal of harmful chemical substances with tangible impacts on public health. This article proposes that this behavior (...) should be interpreted as a form of violence. Examining the regulatory histories of lead, benzene, asbestos and PCBs, the article demonstrates how regulatory obstructionism and violence have become intractable characteristics of the chemical industry.

His analysis placed him outside the major interpretations of fascism in the interwar period. (shrink)

I use some recent formal work on measuring causation to explore a suggestion by James Woodward: that the notion of causal specificity can clarify the distinction in biology between permissive and instructive causes. This distinction arises when a complex developmental process, such as the formation of an entire body part, can be triggered by a simple switch, such as the presence of particular protein. In such cases, the protein is said to merely induce or "permit" the developmental process, whilst the (...) causal "instructions" for guiding that process are already prefigured within the cells. I construct a novel model that expresses in a simple and tractable way the relevant causal structure of biological development and then use a measure of causal specificity to analyse the model. I show that the permissive-instructive distinction cannot be captured by simply contrasting the specificity of two causes as Woodward proposes, and instead introduce an alternative, hierarchical approach to analysing the interaction between two causes. The resulting analysis highlights the importance of focusing on gene regulation, rather than just the coding regions, when analysing the distinctive causal power of genes. (shrink)

One recent topic of debate in Bayesian epistemology has been the question of whether imprecise credences can be rational. I argue that one account of imprecise credences, the orthodox treatment as defended by James M. Joyce, is untenable. Despite Joyce’s claims to the contrary, a puzzle introduced by Roger White shows that the orthodox account, when paired with Bas C. van Fraassen’s Reflection Principle, can lead to inconsistent beliefs. Proponents of imprecise credences, then, must either provide a compelling reason to (...) reject Reflection or admit that the rational credences in White’s case are precise. (shrink)

In 2003, the concept of precarity emerged as the central organizing platform for a series of social struggles that would spread across the space of Europe. Four years later, almost as suddenly as the precarity movement appeared, so it would enter into crisis. To understand precarity as a political concept it is necessary to go beyond economistic approaches that see social conditions as determined by the mode of production. Such a move requires us to see Fordism as exception and precarity (...) as the norm. The political concept and practice of translation enables us to frame the precarity of creative labour in a broader historical and geographical perspective, shedding light on its contestation and relation to the concept of the common. Our interest is in the potential for novel forms of connection, subjectivization and political organization. Such processes of translation are themselves inherently precarious, transborder undertakings. (shrink)

Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks—from the way monkeys in a troop communicate to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this article, we argue there is a tension between how Skyrms talks of signalling networks and his formal measure (...) of information. Although Skyrms refers to both how information flows through networks and that signals carry information, we show that his formal measure only captures the latter. We then suggest that to capture the notion of flow in signalling networks, we need to treat them as causal networks. This provides the formal tools to define a measure that does capture flow, and we do so by drawing on recent work defining causal specificity. Finally, we suggest that this new measure is crucial if we wish to explain how evolution creates information. For signals to play a role in explaining their own origins and stability, they can’t just carry information about acts; they must be difference-makers for acts. _1_ Signalling, Evolution, and Information _2_ Skyrms’s Measure of Information _3_ Carrying Information versus Information Flow _3.1_ Example 1 _3.2_ Example 2 _3.3_ Example 3 _4_ Signalling Networks Are Causal Networks _4.1_ Causal specificity _4.2_ Formalizing causal specificity _5_ Information Flow as Causal Control _5.1_ Example 1 _5.2_ Examples 2 and 3 _5.3_ Average control implicitly ‘holds fixed’ other pathways _6_ How Does Evolution Create Information? _7_ Conclusion Appendix >.

The thesis that agents should calibrate their beliefs in the face of higher-order evidence—i.e., should adjust their first-order beliefs in response to evidence suggesting that the reasoning underlying those beliefs is faulty—is sometimes thought to be in tension with Bayesian approaches to belief update: in order to obey Bayesian norms, it’s claimed, agents must remain steadfast in the face of higher-order evidence. But I argue that this claim is incorrect. In particular, I motivate a minimal constraint on a reasonable treatment (...) of the evolution of self-locating beliefs over time and show that calibrationism is compatible with any generalized Bayesian approach that respects this constraint. I then use this result to argue that remaining steadfast isn’t the response to higher-order evidence that maximizes expected accuracy. (shrink)

While research has focused on financial and social goals in impact investing, we add to the limited research that focuses on how individuals manage identity multiplicity, defined as three or more role identities. Based on our qualitative study of Christian impact investors, we develop a model of identity multiplicity work, explaining how individuals manage their multiple role identities to reduce identity tensions during the process of impact investing. We find individuals engaged in an interactive, ongoing three-step process of identity multiplicity (...) work: prioritizing one of their salient identities, managing their identity multiplicity interrelationships, and reinforcing their prioritized identity. Investors generally prioritized an identity that was neither financial nor social, but rather religious. We also find this identity work implemented through three novel mechanisms: shadowing, one identity casts a shadow over another thereby enabling the simultaneous pursuit of related goals; distinguishing, all identities are retained and at least a minimum threshold of role expectations are met; and surrendering, partial sacrificing of goals of one identity in favor of another identity based on an individual’s self-reflective importance of the role. Our findings offer new insights to multiple identities, impact investing and business ethics literatures. (shrink)

Like Laland et al., I think Mayr’s distinction is problematic, but I identify a further problem with it. I argue that Mayr’s distinction is a false dichotomy, and obscures an important question about evolutionary change.

This essay examines the interconnected nature of salvation and health, and it does so by engaging both recent qualitative research and three scriptural accounts from the life, death, and resurrection of Jesus. In doing so, the essay argues that salvation and health—and their conceptual pairings, sin and disease—are never individualistic. These realities are always cosmic, communal, and interpersonal, even as sin and disease are fundamentally disintegrating and isolating. The salvation and health of people suffering with substance use issues are bound (...) up with the transformations of governing principalities and powers, social realities, and relationships. Health care practitioners and clergy should be wise, communal guides offering care and accompaniment in the pursuit of salvation and health. (shrink)

Two experiments examined the impact of causal relations between features on categorization in 5- to 6-year-old children and adults. Participants learned artificial categories containing instances with causally related features and noncausal features. They then selected the most likely category member from a series of novel test pairs. Classification patterns and logistic regression were used to diagnose the presence of independent effects of causal coherence, causal status, and relational centrality. Adult classification was driven primarily by coherence when causal links were deterministic (...) (Experiment 1) but showed additional influences of causal status when links were probabilistic (Experiment 2). Children’s classification was based primarily on causal coherence in both cases. There was no effect of relational centrality in either age group. These results suggest that the generative model (Rehder, 2003a) provides a good account of causal categorization in children as well as adults. (shrink)
