Sports are an excellent venue for demonstrating evolutionary principles to audiences not familiar with academic research. Team sports and sports fandom feature dynamics of in-group loyalty and intergroup competition, influenced by our evolved coalitional psychology. We predicted that reactions to expressions signaling mutual team/group allegiance would vary as a function of the territorial context. Reactions should become more prevalent, positive, and enthusiastic as one moves from the home territory to a contested area, and from a contested area to a rival’s (...) territory during active rival engagement. We also predicted that men would be more responsive than women based on sex differences in evolved coalitional psychology. The research team visited public places immediately prior to 2016–2017 collegiate football and basketball games. A male research confederate wore a sweatshirt displaying the logo of one of the competing university teams and vocalized the team’s most popular slogan when he saw a fan displaying similar logos. Observers followed 5 m behind, recording reactions and response positivity/enthusiasm. Reaction tone was most positive in the rival territory, least positive in the home territory, and intermediate in the periphery and contested territory. Rates of “no reaction” were lowest in the rival territory but were highest in the periphery. Men had higher reaction rates and more positive and enthusiastic reaction tones than women. Reactions generally followed predictions based on expected signal value. This project provides evidence that coalitional psychology influences dynamics related to university sports team rivalries and that context matters for expressions of alliance. (shrink)

The notion of an enactive system requires thinking about the brain in a way that is different from the standard computational-representational models. In evolutionary terms, the brain does what it does and is the way that it is, across some scale of variations, because it is part of a living body with hands that can reach and grasp in certain limited ways, eyes structured to focus, an autonomic system, an upright posture, etc. coping with specific kinds of environments, and with (...) other people. Changes to any of the bodily, environmental, or intersubjective conditions elicit responses from the system as a whole. On this view, rather than representing or computing information, the brain is better conceived as participating in the action. (shrink)

The thermodynamic behavior is analyzed of a single classical charged particle in thermal equilibrium with classical electromagnetic thermal radiation, while electrostatically bound by a fixed charge distribution of opposite sign. A quasistatic displacement of this system in an applied electrostatic potential is investigated. Treating the system nonrelativistically, the change in internal energy, the work done, and the change in caloric entropy are all shown to be expressible in terms of averages involving the distribution of the position coordinates alone. A convenient (...) representation for the probability distribution is shown to be the ensemble average of the absolute square value of an expansion over the eigenstates of a Schrödinger-like equation, since the heat flow is shown to vanish for each hypothetical “state.” Subject to key assumptions highlighted here, the demand that the entropy be a function of state results in statistical averages in agreement with the form in quantum statistical mechanics. Examining the very low and very high temperature situations yields Planck's and Boltzmann's constants. The blackbody radiation spectrum is then deduced. From the viewpoint of the theory explored here, the method in quantum statistical mechanics of statistically counting the “states” at thermal equilibrium by using the energy eigenvalue structure, is simply a convenient counting scheme, rather than actually representing averages involving physically discrete energy states.

Cross-term conservation relationships for electromagnetic energy, linear momentum, and angular momentum are derived and discussed here. When two or more sources of electromagnetic fields are present, these relationships connect the cross terms that appear in the traditional expressions for the electromagnetic (1) energy, (2) linear momentum, and (3) angular momentum, over to, respectively, (1) the sum of the rates of work, (2) the sum of the forces, and (3) the sum of the torques, that are due to the fields of (...) each charge or current source acting upon the other charge and current sources. These relationships, although not new, appear to be rarely recognized and used in the physics literature. As shown here, they can be extremely helpful for solving and gaining a deeper physical understanding into a rather diverse range of interesting problems in electrodynamics, including (1) aspects of Poynting's theorem when applied to charged point particles, (2) the detailed physical basis of electrostatic analysis, (3) understanding the connection between different techniques used in the past for solving Casimir force problems, and (4) reconciling the invalidity of Newton's third law in electrodynamics.

In the past, a few researchers have presented arguments indicating that a statistical equilibrium state of classical charged particles necessarily demands the existence of a temperature-independent, incident classical electromagnetic random radiation. Indeed, when classical electromagnetic zero-point radiation is included in the analysis of problems with macroscopic boundaries, or in the analysis of charged particles in linear force fields, then good agreement with nature is obtained. In general, however, this agreement has not been found to hold for charged particles bound in (...) nonlinear force fields. The point is raised here that this disagreement arising for nonlinear force fields may be a premature conclusion on this classical theory for describing atomic systems, because past calculations have not directed strict attention to electromagnetic interactions between charges. This point is illustrated here by examining the classical hydrogen atom and showing that this problem has still not been adequately solved. (shrink)

In the game theory literature, Garrett Hardin’s famous allegory of the “tragedy of the commons” has been modeled as a variant of the Prisoner’s Dilemma, labeled the Herder Problem (or, sometimes, the Commons Dilemma). This brief paper argues that important differences in the institutional structures of the standard Prisoner’s Dilemma and Herder Problem render the two games different in kind. Specifically, institutional impediments to communication and cooperation that ensure a dominant strategy of defection in the classic Prisoner’s Dilemma are absent (...) in the Herder Problem. Their absence does not ensure that players will achieve a welfare-enhancing, cooperative solution to the Herders Problem, but does create far more opportunity for players to alter the expected payoffs through cooperative arrangements. In a properly modeled Herder Problem—along the lines of an assurance game—defection would not always be the dominant strategy. Consequently, the Herder Problem is not in the nature of a Prisoner’s Dilemma. (shrink)

An analysis is carried out involving reversible thermodynamic operations on arbitrarily shaped small cavities in perfectly conducting material. These operations consist of quasistatic deformations and displacements of cavity walls and objects within the cavity. This analysis necessarily involves the consideration of Casimir-like forces. Typically, even for the simplest of geometrical structures, such calculations become quite complex, as they need to take into account changes in singular quantities. Much of this complexity is reduced significantly here by working directly with the change (...) in electromagnetic fields as a result of the deformation and displacement changes. A key result of this work is the derivation that for such cavity structures, classical electromagnetic zero-point radiation is the appropriate spectrum at a temperature of absolute zero to ensure that the reversible deformation operations obey both isothermal and adiabatic conditions. In addition, a generalized Wien displacement law is obtained from the demand that the change in entropy of the radiation in these arbitrarily shaped structures must be a state function of temperature and frequency.

In this paper, I will attempt a defense of Hannah Arendt’s usage of the social/political distinction in her “Reflections on Little Rock,” demonstrating that not only is it tenable but also helpful. After distinguishing between her (in)famous distinction between the social and political spheres, I will use the notions of “power,” which is compatible with political freedom, and “force,” which is not, to analyze the strategy of governmentally enforced integration. What I hope to show is that althoughschools are of the (...) utmost political importance, governmental force cannot solve social prejudice, and it cannot legitimately be used outside of the sphere of establishing and protecting legal equality. I will further elucidate Arendt’s illustrative passage on how an integration effort might politically engage problems of exclusion and inequality in schools without having to resort to force to solve social problems and without reducing politics to instrumental administration.

In this essay I defend Heidegger’s critique of technology against possible criticisms that he may be an anti-humanist and a mystic. This essay will show that Heidegger’s critique of technology is helpful in thinking about ecological questions; and his contributions to such questions is relevant and not radically separated from some of the work of other philosophers today including Karen Warren and Marilyn Frye.

In this paper, I elaborate the difference between the concept of infinity and the idea of infinity through Cantor's diagonalization proof to illuminate a passage in Kant's Critique of Judgment. Taking Lyotard's analysis of aesthetic judgments as the basis for my own project, I focus on the idea of a collapse of temporality required for objective cognition and its concomitant preclusion of cognitive subjectivity. Finally, after borrowing language from Hegel's Phenomenology of Spirit, I show that even though there is not (...) a cognitive subject in judgments of the sublime, there is nevertheless a subjectivity that consciousness is tasked with, even if it never fulfills this task when it is confronted with a mathematically sublime object, and it is an subjectivity that would transcend time in order to know the object in-itself.

Decaying wood, while an abundant and stable resource, presents considerable nutritional challenges due to its structural rigidity, chemical recalcitrance, and low nitrogen content. Despite these challenges, certain insect lineages have successfully evolved saproxylophagy (consuming and deriving sustenance from decaying wood), impacting nutrient recycling in ecosystems and carbon sequestration dynamics. This study explores the uneven phylogenetic distribution of saproxylophagy across insects and delves into the evolutionary origins of this trait in disparate insect orders. Employing a comprehensive analysis of gut microbiome data, (...) from both saproxylophagous insects and their non‐saproxylophagous relatives, including new data from unexplored wood‐feeding insects, this Hypothesis paper discusses the broader phylogenetic context and potential adaptations necessary for this dietary specialization. The study proposes the “Detritivore‐First Hypothesis,” suggesting an evolutionary pathway to saproxylophagy through detritivory, and highlights the critical role of symbiotic gut microbiomes in the digestion of decaying wood.

This collection of essays argues that any valid theory of the modern should—indeed must—reckon with the medieval. Offering a much-needed correction to theorists such as Hans Blumenberg, who in his _Legitimacy of the Modern Age_ describes the “modern age” as a complete departure from the Middle Ages, these essays forcefully show that thinkers from Adorno to Žižek have repeatedly drawn from medieval sources to theorize modernity. To forget the medieval, or to discount its continued effect on contemporary thought, is to (...) neglect the responsibilities of periodization. In _The Legitimacy of the Middle Ages_, modernists and medievalists, as well as scholars specializing in eighteenth-, nineteenth-, and twentieth-century comparative literature, offer a new history of theory and philosophy through essays on secularization and periodization, Marx’s theory of commodity fetishism, Heidegger’s scholasticism, and Adorno’s nominalist aesthetics. One essay illustrates the workings of medieval mysticism in the writing of Freud’s most famous patient, Daniel Paul Schreber, author of _Memoirs of My Nervous Illness_. Another looks at Michael Hardt and Antonio Negri’s _Empire_, a theoretical synthesis whose conscientious medievalism was the subject of much polemic in the post-9/11 era, a time in which premodernity itself was perceived as a threat to western values. The collection concludes with an afterword by Fredric Jameson, a theorist of postmodernism who has engaged with the medieval throughout his career. _Contributors_: Charles D. Blanton, Andrew Cole, Kathleen Davis, Michael Hardt, Bruce Holsinger, Fredric Jameson, Ethan Knapp, Erin Labbie, Jed Rasula, D. Vance Smith, Michael Uebel. (shrink)

In this review essay Kevin Murray and Dan Liston examine three texts in what this symposium has deemed the recent resurgence in neo-Marxist accounts of schooling: David Blacker's The Falling Rate of Learning and the Neoliberal Endgame, Mike Cole's Marxism and Educational Theory, and John Marsh's Class Dismissed. Murray and Liston argue that Blacker, Cole, and Marsh provide a much-needed structural delineation of schooling in capitalist society. All three works have substantial merit and are in need of minor (...) adjustments. Blacker's vision is telling and chilling but may need some fine-tuning; Cole's defense of Marxism is commendable but tends toward the disembodied abstract; and Marsh's text capably highlights educationists' blinders but seems to miss elements of a critical structural account. While recognizing real limitations on transformative education under capitalism, Murray and Liston nevertheless elaborate a variation of the radical humanist project. It is their skeletal attempt at an educationally and morally defensible reparative theory. (shrink)

The Current Legal Problems lecture series and annual volume was established around sixty years ago at the Faculty of Laws, University College London and has long been recognized as a major reference point for legal scholarship.

The mass movement of people across the globe constitutes a major feature of world politics today. -/- Whatever the cause of the movement - often war, famine, economic hardship, political repression or climate change - the governments of western capitalist states see this 'torrent of people in flight' as a serious threat to their stability and the scale of this migration indicates a need for a radical re-thinking of both political theory and practice, for the sake of political, social and (...) economic justice. -/- This book argues that there is at present a serious gap between the legal and social practices of immigration and naturalisation in liberal democratic states and any theoretical justification for such practices that can be made within the tradition of liberal political philosophy. How can liberal states develop institutions of democratic citizenship and at the same time justifiably exclude 'outsiders' from participating in those institutions? The book examines various responses to this contradiction within the liberal tradition, and finds none of them satisfactory - there are no consistently liberal justifications for immigration control and this has serious implications both for liberal practice and theory.

This essay explores the mutual reinforcements between socioeconomic precarity and right-wing populism, and then envisions a politics that contests Trumpism through workers’ organizations that create alternatives to predominant patterns of subject formation through work. I first revisit my recent critique of precarity, which initiates a new method of critical theory informed by Paulo Freire’s political pedagogy of popular education. Reading migrant day laborers’ commentaries on their work experiences alongside critical accounts of today’s general work culture, this “critical-popular” procedure yields a (...) conception of precarity with two defining characteristics. First, precarity is socially bivalent: it singles out specific groups for especially harsh treatment even as it pervades society. Second, precarity constitutes subjects through contradictory experiences of time in everyday work-life, exacerbated by insoluble dilemmas of moral responsibility. Antonio Vásquez-Arroyo’s conception of “political literacy” and Bridget Anderson’s notion of “migrantizing the citizen,” in turn, help us understand how precaritization blocks workers from developing the critical dispositions toward time needed for democratic citizenship. This analysis then makes it possible to elucidate, in dialogue with Daniel Martinez-HoSang and Joseph Lowndes, how precaritized worker-citizenship facilitates the cross-class and multiracial appeal of Trumpism’s white supremacist discourse of national economic decline and resurgence, while normalizing the temporal affects of shock and violence characteristic of Trumpism, as theorized by Lia Haro and Romand Coles. Day laborers’ worker centers, I argue, refunction precaritized time, regenerate political literacy, and migrantize the citizen. A large-scale alternative to right-wing populism thus could emerge if the worker center network were expanded throughout the economy. (shrink)

This collection of essays explores the metaphysical thesis that the living world is not made up of substantial particles or things, as has often been assumed, but is rather constituted by processes. The biological domain is organised as an interdependent hierarchy of processes, which are stabilised and actively maintained at different timescales. Even entities that intuitively appear to be paradigms of things, such as organisms, are actually better understood as processes. Unlike previous attempts to articulate processual views of biology, which (...) have tended to use Alfred North Whitehead’s panpsychist metaphysics as a foundation, this book takes a naturalistic approach to metaphysics. It submits that the main motivations for replacing an ontology of substances with one of processes are to be found in the empirical findings of science. Biology provides compelling reasons for thinking that the living realm is fundamentally dynamic, and that the existence of things is always conditional on the existence of processes. The phenomenon of life cries out for theories that prioritise processes over things, and it suggests that the central explanandum of biology is not change but rather stability, or more precisely, stability attained through constant change. This edited volume brings together philosophers of science and metaphysicians interested in exploring the consequences of a processual philosophy of biology. The contributors draw on an extremely wide range of biological case studies, and employ a process perspective to cast new light on a number of traditional philosophical problems, such as identity, persistence, and individuality.

Our rapidly increasing reliance on frictionless AI interactions may increase cognitive and emotional distance, thereby letting our adaptive resilience slacken and our ethical virtues atrophy from disuse. Many trends already well underway involve the offloading of cognitive, emotional, and ethical labor to AI software in myriad social, civil, personal, and professional contexts. Gradually, we may lose the inclination and capacity to engage in critically reflective thought, making us more cognitively and emotionally vulnerable and thus more anxious and prone to manipulation (...) from false news, deceptive advertising, and political rhetoric. In this article, I consider the overarching features of this problem and provide a framework to help AI designers tackle it through system enhancements in smartphones and other products and services in the burgeoning internet of things (IoT) marketplace. The framework is informed by two ideas: psychologist Daniel Kahneman’s cognitive dual process theory and moral self-awareness theory, a four-level model of moral identity that I developed with Benjamin M. Cole. (shrink)

Physicalism, the thesis that everything is physical, is one of the most controversial problems in philosophy. Its adherents argue that there is no more important doctrine in philosophy, whilst its opponents claim that its role is greatly exaggerated. In this superb introduction to the problem Daniel Stoljar focuses on three fundamental questions: the interpretation, truth and philosophical significance of physicalism. In answering these questions he covers the following key topics: -/- (i)A brief history of physicalism and its definitions, (ii)what (...) a physical property is and how physicalism meets challenges from empirical sciences, (iii)'Hempel’s dilemma’ and the relationship between physicalism and physics, (iv)physicalism and key debates in metaphysics and philosophy of mind, such as supervenience, identity and conceivability, and (v)physicalism and causality. -/- Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making Physicalism ideal for those coming to the problem for the first time.

The purpose of the article is to show how the questions of anomality and animality belong together in phenomenology. The figure of the human animal serves as the guideline of the study, namely the figure of a person who is not considered as similar to myself in the frame of a Husserlian characterization of normality. Husserl’s thinking is analyzed with respect to the problem of an intersubjective co-constitution of a common world. It is shown that Husserl only accepts animality and (...) anomality within the restrictive perspective of a so-called normal humanity, that of the adult man, healthy, reasonable and European. However, he constantly strives to include the anomality and animality into humanity as well, an intention that distinguishes him from Heidegger. Heidegger radicalized the question with respect to race, which serves him as a guideline for thinking the very own of the human being. Defending a thinking of exclusion, Heidegger refuses to animals as well as to anomals all right of citizenship in the community of human beings. The article ends by proposing to overcome this duality between an inclusive thinking and an exclusive thinking. (shrink)

This paper raises several concerns about vulnerability as an alternative language to conceptualize injustice and politicize its attendant injuries. First, the project of resignifying “vulnerability” by emphasizing its universality and amplifying its generative capacity, I suggest, might dilute perceptions of inequality and muddle important distinctions among specific vulnerabilities, as well as differences between those who are injurable and those who are already injured. Vulnerability scholars, moreover, have yet to elaborate the path from acknowledging constitutive vulnerability to addressing concrete injustices. Second, (...) vulnerability studies respond to, and have been shaped by, debates in the 1980s and 1990s over oppression, identity and agency. This genealogy needs to be acknowledged and evaluated. As I demonstrate, prominent theorists define vulnerability in contradistinction to victimization, adopting neo-liberal formulations of victims and victimhood. Finally, I turn to address the politics of vulnerability. At issue are not simply matters of utility or programmes for implementation, but the fraught relationship among ontology, ethics and politics, which I address through an engagement with Rancière's conception of the political and the case of the Black Lives Matter movement.

I contend that mathematical domains are freestanding institutional entities that, at least typically, are introduced to serve representational functions. In this paper, I outline an account of institutional reality and a supporting metaontological perspective that clarify the content of this thesis. I also argue that a philosophy of mathematics that has this thesis as its central tenet can account for the objectivity, necessity, and atemporality of mathematics.

This textbook brings the humanities to students in order to evoke the humanity of students. It helps to form individuals who take charge of their own minds, who are free from narrow and unreflective forms of thought, and who act compassionately in their public and professional worlds.

It encourages them to (...) consider the ethical and existential issues related to the experience of disease, care of the dying, health policy, religion and health, and medical technology. Case studies, images, questions for discussion, and role-playing exercises help readers to engage in the practical, interpretive, and analytical aspects of the material, developing skills for critical thinking as well as compassionate care.

Stereotypes of social construction suggest that the existence of social constructs is accidental and that such constructs have arbitrary and subjective features. In this paper, I explore a conception of social construction according to which it consists in the collective imposition of function onto reality and show that, according to this conception, these stereotypes are incorrect. In particular, I argue that the collective imposition of function onto reality is typically non-accidental and that the products of such imposition frequently have non-arbitrary (...) and objective features. These conclusions are interesting in and of themselves since they debunk important aspects of our socially constructed conception of social construction. Yet, additionally, they have important implications for the viability of mathematical social constructivism since resistance to such constructivism is frequently grounded in the observation that mathematics is non-accidental, non-arbitrary, and objective. As a secondary focus, I explore these implications in this paper. (shrink)

What is like to live without touch or movement/position sense? The only way to understand the importance of these senses, so familiar we cannot imagine their absence, is to ask someone in that position. Ian Waterman lost them below the neck over forty years ago, though pain and temperature perception and his peripheral movement nerves were unaffected. Without proprioceptive feedback and touch the movement brain was disabled. Completely unable to move, he felt disembodied and frightened. Then, slowly, he taught himself (...) to dress, eat and walk by thinking about each movement and with visual supervision. In Losing Touch, the narrative moves between biography and scientific research, theatre, documentary and zero gravity. The book is the result of nearly 30 years close collaboration between author and subject. (shrink)

This chapter draws on insights from non-equilibrium thermodynamics to demonstrate the ontological inadequacy of the machine conception of the organism. The thermodynamic character of living systems underlies the importance of metabolism and calls for the adoption of a processual view, exemplified by the Heraclitean metaphor of the stream of life. This alternative conception is explored in its various historical formulations and the extent to which it captures the nature of living systems is examined. Following this, the chapter considers the metaphysical (...) implications of reconceptualizing the organism from complex machine to flowing stream. What do we learn when we reject the mechanical and embrace the processual? Three key lessons for biological ontology are identified. The first is that activity is a necessary condition for existence. The second is that persistence is grounded in the continuous self-maintenance of form. And the third is that order does not entail design. (shrink)

Thought experiments have been used by philosophers for centuries, especially in the study of personal identity where they appear to have been used extensively and indiscriminately. Despite their prevalence, the use of thought experiments in this area of philosophy has been criticized in recent times. Bernard Williams criticizes the conclusions that are drawn from some experiments, and retells one of these experiments from a different perspective, a retelling which leads to a seemingly opposing result. Wilkes criticizes the method of thought (...) experimentation itself, suggesting that the results drawn from the experiments are tainted by a faulty method. This paper examines both these types of objection, and concludes that neither can be sustained. (shrink)

Empirical studies of gesture in a subject who has lost proprioception and the sense of touch from the neck down show that specific aspects of gesture remain normal despite abnormal motor processes for instrumental movement. The experiments suggest that gesture, as a linguistic phenomenon, is not reducible to instrumental movement. They also support and extend claims made by Merleau-Ponty concerning the relationship between language and cognition. Gesture, as language, contributes to the accomplishment of thought.
