Recently the CJEU decision in the case of ‘Ewa Glawischnig-Piesczek v. Facebook Ireland Limited’ has raised the issue of the transcultural/trans-territorial signification of hate speech and hate crimes. Taking a cue from this decision and the related semiotic/legal implications, the paper proposes an analysis of the semio/pragmatic conditions for the production of performativity inherent in hate speech across different cultural universes of discourse. Given that web-based digital communication is global—at least, potentially—regardless of any spatial/political compartmentalization, it crosses different semio-cultural circuits. (...) This trans-spatiality implies transcultural crossings that can multiply and even transfigure the semantic implications of the original signifier and the related prognoses of ‘semantic effectiveness.’ Cultural boundaries therefore may function as a kind of ‘horizon of events’ for hate speech and, more inclusively, all linguistic acts and their legal signification/classification. The question then arises regarding whether and to what extent the performativity of hate speech is able to withstand the variation of cultural boundary conditions. Insofar as cultures are universes of experience, the issue to be investigated broadens, and ends up invoking the question of whether or not the production of performativity implicitly presupposes and tacitly epitomizes the semio-pragmatic implications/consequences (or, in Peircean terms, ‘bearings’) coextensive with cultural universes of experience. Were this the case, it would seem to call into question the very possibility of ‘making things only with words,’ or more explicitly, the alleged meaning of ‘linguistic acts.’. (shrink)

Although the laws of thermodynamics are well established for black hole horizons, much less has been said in the literature to support the extension of these laws to more general settings such as an asymptotic de Sitter horizon or a Rindler horizon (the event horizon of an asymptotic uniformly accelerated observer). In the present paper we review the results that have been previously established and argue that the laws of black hole thermodynamics, as well as their (...) underlying statistical mechanical content, extend quite generally to what we call here “causal horizons.” The root of this generalization is the local notion of horizon entropy density.

An analogue of Hawking's black hole area theorem is proved for Friedmann-type cosmological models with event horizons. The generalised second law of thermodynamics is investigated in cases where the horizon shrinks.

Experiences of shame are not always discrete, but can be recurrent, persistent or enduring. To use the feminist phenomenologist Sandra Lee Bartky’s formulation, shame is not always an acute event, but can become a “pervasive affective attunement” (Bartky, 1990 : 85). Instead of experiencing shame as a discrete event with a finite duration, it can be experienced as a persistent, and perhaps, permanent possibility in daily life. This sort of pervasive or persistent shame is commonly referred to as (...) “chronic shame” (Pattison, 2000 ; Nathanson, 1992 ; Dolezal, 2015 ). Chronic shame is frequently associated with political oppression and marginalization. In chronic shame, it is the potentiality of shame, rather than the actuality, that is significant. In other words, the anticipation of shame (whether explicit or implicit) comes to be a defining feature of one’s lived experience. Living with chronic shame has important socio-political consequences. Thus far, chronic shame has eluded simple phenomenological analysis, largely because chronic shame often does not have a clear experiential profile: it is frequently characterised by the _absence_ rather than the _presence_ of shame. The aim of this article is to provide a phenomenology of chronic shame, drawing from Edmund Husserl’s formulation of the ‘horizon’ as a means a to discuss structural aspects of chronic shame experiences, in particular how chronic shame is characterised by structures of absence and anticipation.

When we think of improvised musical performance, we commonly think of musicians engaged in an activity that brings forth a musical event of some kind. This activity is both situated and situating—it occurs in a particular locale and the event itself situates the players who are literally located within that event. This paper explores how we might understand the spatio-temporal field in which improvising musicians are situated when they perform. To comprehend what I refer to as the (...) “horizonal field” of improvised musical performance requires understanding the nature of listening and hearing, the materiality of sound, and the spatio-temporal qualities of the audible event itself. Considering each of these topics, this paper presents the “horizonal field” of improvised musical performance as a particular region bounded by silence. (shrink)

Surface presentism is the combination of a general relativistic physics with a presentist metaphysics. In this paper, we provide an argument against this combination based on black holes. The problem focuses on the notion of an event horizon. We argue that the present locations of event horizons are ontologically dependent on future black hole regions, and that this dependence is incompatible with presentism. We consider five responses to the problem available to the surface presentist, and argue that (...) none succeed. Surface presentism thus faces the prospect of refutation based on evidence that confirms the existence of black holes. (shrink)

The generalized second law of thermodynamics states that entropy always increases when all event horizons are attributed with an entropy proportional to their area. We test the generalized second law by investigating the change in entropy when dust, radiation and black holes cross a cosmological event horizon. We generalize for flat, open and closed Friedmann–Robertson–Walker universes by using numerical calculations to determine the cosmological horizon evolution. In most cases, the loss of entropy from within the cosmological (...) horizon is more than balanced by an increase in cosmological event horizon entropy, maintaining the validity of the generalized second law of thermodynamics. However, an intriguing set of open universe models shows an apparent entropy decrease when black holes disappear over the cosmological event horizon. We anticipate that this apparent violation of the generalized second law will disappear when solutions are available for black holes embedded in arbitrary backgrounds. (shrink)

Niels Bohr famously argued that a consistent understanding of quantum mechanics requires a new epistemic framework, which he named complementarity . This position asserts that even in the context of quantum theory, classical concepts must be used to understand and communicate measurement results. The apparent conflict between certain classical descriptions is avoided by recognizing that their application now crucially depends on the measurement context. ;Recently it has been argued that a new form of complementarity can provide a solution to the (...) so-called information loss paradox. Stephen Hawking argues that the evolution of black holes cannot be described by standard unitary quantum evolution, because such evolution always preserves information, while the evaporation of a black hole will imply that any information that fell into it is irrevocably lost---hence a "paradox." Some researchers in quantum gravity have argued that this paradox can be resolved if one interprets certain seemingly incompatible descriptions of events around black holes as instead being complementary. ;In this dissertation I assess the extent to which this black hole complementarity can be undergirded by Bohr's account of the limitations of classical concepts. I begin by offering an interpretation of Bohr's complementarity and the role that it plays in his philosophy of quantum theory. After clarifying the nature of classical concepts, I offer an account of the limitations these concepts face, and argue that Bohr's appeal to disturbance is best understood as referring to these conceptual limits. ;Following preparatory chapters on issues in quantum field theory and black hole mechanics, I offer an analysis of the information loss paradox and various responses to it. I consider the three most prominent accounts of black hole complementarity and argue that they fail to offer sufficient justification for the proposed incompatibility between descriptions. ;The lesson that emerges from this dissertation is that we have as much to learn from the limitations facing our scientific descriptions as we do from the successes they enjoy. Because all of our scientific theories offer at best limited, effective accounts of the world, an important part of our interpretive efforts will be assessing the borders of these domains of description.

The practice of personal autonomy is a dynamic event that consists of a vital interplay between the self, socio-cultural reality, meaning, and being epistemically responsible. Autonomy is not static, something that we simply possess by virtue of a status as 'rational beings'. Therefore, in this dissertation, I examine the traditional notion of autonomy as it has been developed by Kant and subsequently influenced the current debate between 'liberals' and 'communitarians'. Primarily from the standpoint of the critiques developed by Charles (...) Taylor, I argue that the fundamental disagreement between these two camps is over the concept of the self. While this landscape stands divided, some middle ground can be found in the work of Joseph Raz, who postulated the need for a combination of individual abilities and an autonomy-supporting environment as necessary conditions for practicing personal autonomy. His characterization of 'personal autonomy', distinct from Kantian autonomy, forms the underlying paradigm for this work. (shrink)

Paul Ricœur’s recourse to the metahistorical categories, space of experience and horizon of expectation, invites an inquiry into geography’s role as the guarantor of history. The ontology of the flesh provides the first indication of how one’s body is implicated in the sense of one’s place in the world. In turn, narrative inscriptions of events on the landscape transform the physical topography of a place into an array of sites where memories of ancestral wisdom and historical traumas endure. By (...) anchoring historians’ representations of the past in the places and locales in which events took place, geography constructs a third space analogous to the third time of history. The aporias engendered by the phenomenology of time, however, have no equivalent in the phenomenology of space. The dissymmetry between the dialectic that informs the discourse of space and the one that informs the discourse of time thus keeps in place the reciprocal relation between geography and historiography.

We develop a new understanding of the historical horizon of event ontology. Within the general area of the philosophy of nature, event ontology is a still emerging field of investigation in search for the ultimate materialist ontology of the world. While event ontology itself will not be explicated in full mathematical details here, our focus is on its conceptual interrelation with the dominant current of Idealism in Western thought approached by us as a problem in the (...) history of ideas. Our presentation is designed to be accessible to a wider audience. We especially highlight the deep connection between event ontology and postmodernism in general, and the post-war French philosophers Althusser, Foucault, Deleuze, and Guattari in particular, who are viewed as main sources for current and future programs of abstract materialism.

We extend attribution and stakeholder theory in the context of crisis reputation management by examining differences in stakeholder perceptions in the form of organization-related blame. We presented eight stakeholder groups with factual information surrounding the Deepwater Horizon Oil Spill and asked them to indicate the extent to which they blamed the leaders and organizations associated with the event. Stakeholders also completed a survey assessing their attribution styles. Results indicated that perceptions of blame were affected by the interaction of (...) stakeholder role (i.e., active vs. passive) with attribution style (i.e., optimistic vs. pessimistic). Our results suggest that organizational leaders’ understanding of their stakeholders may be an important aspect in managing stakeholders’ sensemaking during crises. (shrink)

A major problem threatens Deleuze’s project in The Logic of Sense. He makes an ontological distinction between events and substances, but he then collapses a crucial distinction between two kinds of events, namely, actions and mere occurrences. Indeed, whereas actions are commonly differentiated from mere occurrences with reference to their causal dependence on the intentions of their agents, Deleuze asserts a strict ontological distinction between the realm of causes and the realm of events, and holds that events of all types (...) are incorporeal happenings which are inseparable from expressed sense. For Deleuze, what counts as one’s action thus does not depend on one’s intention, but rather on a process of “making sense” of that action. Nevertheless, Deleuze continues to speak of the need to “will” the event. In order to resolve this apparent contradiction, I will read a conception of “expressive agency” into The Logic of Sense.

Many decisions involve multiple stages of choices and events, and these decisions can be represented graphically as decision trees. Optimal decision strategies for decision trees are commonly determined by a backward induction analysis that demands adherence to three fundamental consistency principles: dynamic, consequential, and strategic. Previous research found that decision-makers tend to exhibit violations of dynamic and strategic consistency at rates significantly higher than choice inconsistency across various levels of potential reward. The current research extends these findings under new conditions; (...) specifically, it explores the extent to which these principles are violated as a function of the planning horizon length of the decision tree. Results from two experiments suggest that dynamic inconsistency increases as tree length increases; these results are explained within a dynamic approach–avoidance framework. (shrink)

This paper identifies the duty to care for the public interest in the commonly valued ecological goods of the Gulf as one of the basic essential features of the moral significance of the federal policies that govern the Deepwater Horizon Oil Spill. I argue that the Clean Water Act and the Oil Protection Act implicitly provide for a communitarian interpretation of the public and ecological goods of this event that warrants a virtue ethical account of normativity that is (...) ultimately expressed in the duty to care, a duty that is one of the central moral principles that underlies the punitive damages doctrine.

This is a phenomenological description of what is happening when we experience the death of another that interprets surviving or living on after such death by employing the term event. This term of art from phenomenology and hermeneutics is used to describe a disruptive and transformative experience of singularity. I maintain that the death of the other is an experience of an event because such death is unpredictable or without a horizon of expectation, excessive or without any (...) principle of sufficient reason, and transformative or a death of the world itself.

'An urgent and extraordinary book. Weaving a philosophical analysis of Heidegger, Agamben and Foucault, Jan draws out the implications of their thought for a radical analysis of the ontological politics of Islam and Pakistan. Whether writing about the 'Ulama and Deoband schools, blasphemy laws, the military, beards, or the Bamiyan Buddhas, Jan provokes and challenges our thinking while unearthing the ground on which Pakistan—and our world—are built.' —Joel Wainwright, Department of Geography, Ohio State University, USA 'In this exceptionally inventive and (...) important book, Jan shows us that the problems besetting political life in Pakistan are part of a more troubling crisis in modern forms of power. Challenging accounts that cordon off "political Islam" from "the West," Jan discloses their fundamental indistinction and thus, through his practice of critical ontology, reorients our understanding of how power and violence are at work in the world.' —Joshua Barkan, Department of Geography, University of Georgia, USA The Metacolonial State presents a novel rethinking of the relationship between Islam and the Political. Key to the text is an original argument regarding the "biopoliticization of Islam" and the imperative need for understanding sovereign power and the state of exception in resolutely ontological terms. Through the formulation of a critical ontology of political violence, The Metacolonial State endeavors to shed new light on the signatures of power undergirding postcolonial life, while situating Pakistan as a paradigmatic site for reflection on the nature of modernity's precarious present. The cross-disciplinary approach of Dr. Jan's work is certain to have broad appeal among geographers, historians, anthropologists, postcolonial theorists, and political scientists, among others. At the same time, his explication of critical ontology – with its radical reading of the interlacement of history, power and the event – promises to add a bold new dimension to social science research on Islamism and biopolitics.

EVENTAL AESTHETICS RETROSPECTIVE 1. LOOKING BACK AT 10 ISSUES OF EVENTAL AESTHETICS.

Our contributors explore a rich variety of aesthetic problems that bring about the self-reflexive re-evaluation of ideas.

Is aesthetics a product of evolution? Are human aesthetic behaviors in fact evolutionary adaptations? The creation of artistic objects and experiences is an important aesthetic behavior. But so is the perception of aesthetic phenomena qua aesthetic. The question of evolutionary aesthetics is whether humans have evolved the capacity not only to make beautiful things but also to appreciate the aesthetic qualities in things. Are our near-universal love of music and cute baby animals essential to our species’ evolutionary development, which took (...) place over thousands of years? In other words, do aesthetic practice and appreciation help people to survive or reproduce? Do aesthetic behaviors help to propel natural selection? If so, what does that tell us about ourselves as human beings? What does it tell us about art, our other aesthetic practices, and aesthetic experience? (shrink)

In her book, Vibrant Matter, Jane Bennett thinks through what ontological, political, and ecological questions would look like if humans could admit that matter and nonhuman things are living, creative agents; the contributors to this issue of Evental Aesthetics begin to think through what aesthetic questions would look like.

This issue is dedicated to thinking about art and current aesthetic perspectives through Hegelianism.

In this special issue on animals and aesthetics, contributors explore encounters with animals in art and thought.

In this issue, our contributors demonstrate how art in the city, art “about” the city, art compared to the city, can bring to attention the insidious forces underlying every city’s gleaming, wide-awake veneer.

In "Aesthetic Histories" our contributors’ shared concern is the inspiring and confounding, healthy and uncomfortable and above all inevitable relationship between history and aesthetic praxis.

A hijacking is a violent takeover, a misappropriation of something for a purpose other than its intended one, by parties other than those for whom the thing was meant. This issue explores the aesthetic practices and consequences of unauthorized repurposing.

This issue profiles various attempts, both successful and fraught, to engage the divide between asceticism and opulence, between materialism and poverty.

The two competitive currents in French philosophy initiated by Jacques Derrida and Gilles Deleuze tackle the difference between empiricism and idealism in contrary motion. In Derrida, the move is toward a critique of representation. In Deleuze, it is toward recovery of the real. Nevertheless, this paper nominates their meeting in a kind of 'radical empiricism'. Both Derrida and Deleuze engage with empiricism at certain points in their work, although many who go by that label would be surprised to hear it.

This paper discusses some philosophical aspects related to the recent publication of the experimental results of the 2017 black hole experiment, namely the first image of the supermassive black hole at the center of galaxy M87. In this paper I present a philosophical analysis of the 2017 Event Horizon Telescope (EHT) black hole experiment. I first present Hacking’s philosophy of experimentation. Hacking gives his taxonomy of elements of laboratory science and distinguishes a list of elements. I show that (...) the EHT experiment conforms to major elements from Hacking’s list. I then describe with the help of Galison’s Philosophy of the Shadow how the EHT Collaboration created the famous black hole image. Galison outlines three stages for the reconstruction of the black hole image: Socio-Epistemology, Mechanical Objectivity, after which there is an additional SocioEpistemology stage. I subsequently present my own interpretation of the reconstruction of the black hole image and I discuss model fitting to data. I suggest that the main method used by the EHT Collaboration to assure trust in the results of the EHT experiment is what philosophers call the Argument from Coincidence. I show that using this method for the above purpose is problematic. I present two versions of the Argument from Coincidence: Hacking’s Coincidence and Cartwright’s Reproducibility by which I analyse the EHT experiment. The same estimation of the mass of the black hole is reproduced in four different procedures. The EHT Collaboration concludes: the value we have converged upon is robust. I analyse the mass measurements of the black hole with the help of Cartwright’s notion of robustness. I show that the EHT Collaboration construe Coincidence/Reproducibility as Technological Agnosticism and I contrast this interpretation with van Fraassen’s scientific agnosticism. (shrink)

On the 10th of April, 2019 the Event Horizon Telescope Collaboration presented the first image of the black hole. The image was obtained with a planet-scale array of eight ground-based radio telescopes. The observation relied on a technique called very long base interferometry which synchronises telescope facilities around the world. The image of a black hole together with the recent detections of gravitational waves confirms one of the most intriguing predictions of Einstein’s gravity theory, namely, the existence of (...) black holes. I will provide more details on this remarkable observation and explore its consequences for our understanding of nature. The physical reality of black holes is strongly supported by recent advances of astronomy. I claim that this fact is the key to understanding the relation between our world and the world of mathematics. (shrink)

The central idea of this paper is that forming the black hole horizon is attended with the transition from the classical regime of evolution to the quantum one. We offer and justify the following criterion for discriminating between the classical and the quantum: creations and annihilations of particle-antiparticle pairs are impossible in the classical reality but possible in the quantum reality. In flat spacetime, we can switch from the classical picture of field propagation to the quantum picture by changing (...) the overall sign of the spacetime signature. To describe a self-gravitating object at the final stage of its classical evolution, we propose to use the Foldy–Wouthuysen representation of the Dirac equation in curved spacetimes, and the Gozzi classical path integral. In both approaches, maintaining the dynamics in the classical regime is controlled by supersymmetry. (shrink)

This paper warns against destructive effects of subjectivist thinking. Subjectivist accounts, as Alan Sokal exposed, promote a distorted view of scientific practice. For example, Einstein's 1905 special theory of relativity relied on data produced by Fizeau, a physicist trained in classical mechanics. Einstein's use of Fizeau's results shows that the ontological foundation of uncontroversial data transcends conventional speculations. Einstein's employment of Fizeau's results mitigates against ideas such as paradigm shifts and revolutionary science. Instead, the ontology of shared horizons of fact (...) remains largely unadulterated. The descriptions scientists use accommodate received view shifts, but the horizon of fact remains unimpeachably the same. The apt performance of science shows what it means to move further away from error. The only direction away from error is toward truth. To deny the reality of this directionality flies in the face of common sense and prudent science. (shrink)

It is shown that certain kinds of behavior, which hitherto were expected to be characteristic for classical gravity and quantum field theory in curved spacetime, as the infinite dimensional Bondi-Metzner-Sachs symmetry, holography on event horizons and an area proportionality of entropy, have in fact an unnoticed presence in Minkowski QFT.This casts new light on the fundamental question whether the volume proportionality of heat bath entropy and the (logarithmically corrected) dimensionless area law obeyed by localization-induced thermal behavior are different geometric (...) parametrizations which share a common primordial algebraic origin. Strong arguments are presented that these two different thermal manifestations can be directly related, this is in fact the main aim of this paper.It will be demonstrated that QFT beyond the Lagrangian quantization setting receives crucial new impulses from holography onto horizons.The present paper is part of a project aimed at elucidating the enormous physical range of “modular localization”. The latter does not only extend from standard Hamiltonian heat bath thermal states to thermal aspects of causal- or event-horizons addressed in this paper. It also includes the recent understanding of the crossing property of formfactors whose intriguing similarity with thermal properties was, although sometimes noticed, only sufficiently understood in the modular setting (Schroer in arXiv:0905.4006 (2009)).

Jacob Bekenstein's identification of black hole event horizon area with entropy proved to be a landmark in theoretical physics. In this paper we trace the subsequent development of the resulting generalized second law of thermodynamics (GSL), especially its extension to incorporate cosmological event horizons. In spite of the fact that cosmological horizons do not generally have well-defined thermal properties, we find that the GSL is satisfied for a wide range of models. We explore in particular the case (...) of an asymptotically de Sitter universe filled with a gas of small black holes as a means of casting light on the relative entropic ‘worth’ of black hole versus cosmological horizon area. We present some numerical solutions of the generalized total entropy as a function of time for certain cosmological models, in all cases confirming the validity of the GSL. (shrink)

In 1981 Unruh proposed that fluid mechanical experiments could be used to probe key aspects of the quantum phenomenology of black holes. In particular, he claimed that an analogue to Hawking radiation could be created within a fluid mechanical `dumb hole', with the event horizon replaced by a sonic horizon. Since then an entire sub-field of `analogue gravity' has been created. In 2016 Steinhauer reported the experimental observation of quantum Hawking radiation and its entanglement in a Bose-Einstein (...) condensate analogue black hole. What can we learn from such analogue experiments? In particular, in what sense can they provide evidence of novel phenomena such as black hole Hawking radiation? (shrink)
