This book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop (...) quantum gravity.

Relationships between current theories, and relationships between current theories and the sought theory of quantum gravity (QG), play an essential role in motivating the need for QG, aiding the search for QG, and defining what would count as QG. Correspondence is the broad class of inter-theory relationships intended to demonstrate the necessary compatibility of two theories whose domains of validity overlap, in the overlap regions. The variety of roles that correspondence plays in the search for QG are illustrated, using examples (...) from specific QG approaches. Reduction is argued to be a special case of correspondence, and to form part of the definition of QG. Finally, the appropriate account of emergence in the context of QG is presented, and compared to conceptions of emergence in the broader philosophy literature. It is argued that, while emergence is likely to hold between QG and general relativity, emergence is not part of the definition of QG, and nor can it serve usefully in the development and justification of the new theory.

How much of philosophical, scientific, and political thought is caught up with the idea of continuity? What if it were otherwise? This paper experiments with the disruption of continuity. The reader is invited to participate in a performance of spacetime (re)configurings that are more akin to how electrons experience the world than any journey narrated though rhetorical forms that presume actors move along trajectories across a stage of spacetime (often called history). The electron is here invoked as our host, an (...) interesting body to inhabit (not in order to inspire contemplation of flat-footed analogies between ‘macro’ and ‘micro’ worlds, concepts that already presume a given spatial scale), but a way of thinking with and through dis/continuity – a dis/orienting experience of the dis/jointedness of time and space, entanglements of here and there, now and then, that is, a ghostly sense of dis/continuity, a quantum dis/continuity. There is no overarching sense of temporality, of continuity, in place. Each scene diffracts various temporalities within and across the field of spacetimemattering. Scenes never rest, but are reconfigured within, dispersed across, and threaded through one another. The hope is that what comes across in this dis/jointed movement is a felt sense of différance, of intra-activity, of agential separability – differentiatings that cut together/apart – that is the hauntological nature of quantum entanglements.

In times of crisis, when current theories are revealed as inadequate to task, and new physics is thought to be required—physics turns to re-evaluate its principles, and to seek new ones. This paper explores the various types, and roles of principles that feature in the problem of quantum gravity as a current crisis in physics. I illustrate the diversity of the principles being appealed to, and show that principles serve in a variety of roles in all stages of the crisis, (...) including in motivating the need for a new theory, and defining what this theory should be like. In particular, I consider: the generalised correspondence principle, UV-completion, background independence, and the holographic principle. I also explore how the current crisis fits with Friedman’s view on the roles of principles in revolutionary theory-change, finding that while many key aspects of this view are not represented in quantum gravity, the view could potentially offer a useful diagnostic, and prescriptive strategy. This paper is intended to be relatively non-technical, and to bring some of the philosophical issues from the search for quantum gravity to a more general philosophical audience interested in the roles of principles in scientific theory-change.

Definition of the problem Death and suicide wishes of older people represent a relevant and morally challenging issue for nurses. Especially in the context of wishes for assisted suicide, the risk for the development of moral uncertainty or even moral distress grows. As suicide rates and requests for assisted suicide are particularly high among people 65 years of age or older, the topic proves to be particularly relevant to the settings of long-term community and nursing home care. At the same (...) time, this fact underlines the importance of suicide prevention, which has recently been strengthened by the federal government, with the intention of launching a national strategy and a corresponding law. Arguments According to our hypothesis, the situational confrontation of nursing professionals with death and suicide wishes may cause an ethical field of tension between an unprejudiced, open, empathetic and respectful acceptance of death and suicide wishes on the one hand and the goal of suicide prevention on the other. The legal uncertainties in regards to the practice of assisted suicide, which currently prevails in practice, may intensify this risk. International studies point to the potential of moral distress of nurses when confronted with death and suicide wishes. Conclusion These findings and the reference to the current legal uncertainties and framework conditions in the national (German) context underpin the importance of the professional discussion about the topic, the need to sensitise (future) nursing professionals to potential ethical tensions and to enable them to deal with the accompanying moral uncertainty in a professional and competent manner.

Feelings of gratitude toward the natural environment are problematic because gratitude seems to be an appropriate response to someone’s intentional decision to benefit us, and ecosystems that sustain human life do not choose to do so. In accordance with one defense of the rationality and appropriateness of gratitude toward nature, intentional action can be regarded as not being a necessary condition for feelings of gratitude. Instead, gratitude toward an entity can be considered both rational and appropriate when (1) that entity (...) is the source of a valuable and unearned benefit and (2) the benefit did not result from some accidental and/or regrettable feature of that entity’s character. According to this analysis, we can provide a rational ground for gratitude to particular ecosystems by citing the valuable and unearned benefits that we receive from those systems and by demonstrating that these benefits result from elements within the ecosystems that are neither regrettable nor accidental.

Typically, a less fundamental theory, or structure, emerging from a more fundamental one is an example of synchronic emergence. A model emerging from a prior model upon which it nevertheless depends is an example of diachronic emergence. The case of spacetime emergent from quantum gravity and quantum cosmology challenges these two conceptions of emergence. Here, I propose two more-general conceptions of emergence, analogous to the synchronic and diachronic ones, but which are potentially applicable to the case of emergent spacetime: an (...) inter-level, hierarchical conception, and an intra-level, ‘flat’ conception. I then explore whether, and how, these ideas may be applicable in the case of several putative examples of relativistic spacetime emergent from the non-spatiotemporal structures described by different approaches to quantum gravity, and of spacetime emergent from a non-spatiotemporal ‘big bang’ state according to different examples of quantum cosmology.

An effective theory in physics is one that is supposed to apply only at a given length scale; the framework of effective field theory describes a ‘tower’ of theories each applying at different length scales, where each ‘level’ up is a shorter-scale theory. Owing to subtlety regarding the use and necessity of EFTs, a conception of emergence defined in terms of reduction is irrelevant. I present a case for decoupling emergence and reduction in the philosophy of physics. This paper develops (...) a positive conception of emergence, based on the novelty and autonomy of the ‘levels’, by considering physical examples, involving critical phenomena, the renormalisation group, and symmetry breaking. This positive conception of emergence is related to underdetermination and universality, but, I argue, is preferable to other accounts of emergence in physics that rely on universality. (shrink)

Within physics there are two ways of establishing the relative fundamentality of one theory compared to another, via two senses of reduction: "inter-level" and "intra-level" (Crowther, 2018). The former is standardly recognised as roughly correlating with the chain of ontological dependence (i.e., the phenomena described by theories of macro-physics are typically supposed to be ontologically dependent on the entities/behaviour described by theories of micro-physics), and thus has been of interest to naturalised metaphysics. The latter, though, has not been considered interesting (...) for metaphysics, because it is not thought to correlate either with ontological dependence, nor causal or dynamical dependence. I argue, however, that this is a mistake, and that actually, the intra-level relation does reflect ontological dependence (in the same sense as the inter-level relation) and thus should not be neglected by metaphysics of physics. This argument further supports the assertion that the same notion of fundamentality underlies both the inter- and intra-level claims of fundamentality in physics, and that this notion of relative fundamentality in physics correlates with that of metaphysics.

Singularities in general relativity and quantum field theory are often taken not only to motivate the search for a more-fundamental theory (quantum gravity, QG), but also to characterise this new theory and shape expectations of what it is to achieve. Here, we first evaluate how particular types of singularities may suggest an incompleteness of current theories. We then classify four different 'attitudes' towards singularities in the search for QG, and show, through examples in the physics literature, that these lead to (...) different scenarios for the new theory. Two of the attitudes prompt singularity resolution, but only one suggests the need for a theory of QG. Rather than evaluate the different attitudes, we close with some suggestions of factors that influence the choice between them. (shrink)

Quantum gravity is understood as a theory that, in some sense, unifies general relativity (GR) and quantum theory, and is supposed to replace GR at extremely small distances (high-energies). It may be that quantum gravity represents the breakdown of spacetime geometry described by GR. The relationship between quantum gravity and spacetime has been deemed ``emergence'', and the aim of this thesis is to investigate and explicate this relation. After finding traditional philosophical accounts of emergence to be inappropriate, I develop a (...) new conception of emergence by considering physical case studies including condensed matter physics, hydrodynamics, critical phenomena and quantum field theory understood as effective field theory. This new conception of emergence is unconcerned with the ideas of reduction and derivation (i.e. it holds that we may have emergence with reduction or without it). Instead, a low-energy theory (or model) is understood as emergent from a high-energy theory if it is novel and autonomous compared to the high-energy theory, and the low-energy physics is dependent in a particular, minimal sense on the high-energy physics (this dependence is revealed by the techniques of effective field theory and the renormalisation group). While novelty is construed in a broad sense, the autonomy comes essentially from the underdetermination of the high-energy theory by the low-energy theory, which reflects the minimal way in which the emergent, low-energy theory depends on the high-energy one. It results from the scaling behaviour of the theories and the limiting relations between them, and is demonstrated by the renormalisation group and effective field theory techniques, the idea of universality, and the phenomenon of symmetry-breaking. These ideas are important in exploring the relationship between quantum gravity and GR, where GR is understood as an effective, low-energy theory of quantum gravity. Without experimental data or a theory of quantum gravity, we rely on principles and techniques from other areas of physics to guide the way. As well as considering the idea of emergence appropriate to treating GR as an effective field theory, I investigate the emergence of spacetime (and other aspects of GR) in several concrete approaches to quantum gravity, including examples of the condensed matter approaches, the ``discrete approaches'' (causal set theory, causal dynamical triangulations, quantum causal histories and quantum graphity) and loop quantum gravity.

In this introduction, we describe the rationale behind this special issue on Principles of Quantum Gravity. We explain what we mean by ‘principles’ and relate this to the various contributions. Finally, we draw out some general themes that can be found running throughout these contributions.

This paper addresses a central interpretive problem in understanding Pierre Duhem's philosophy of science. The problem arises because there is textual support for both realist and antirealist readings of his work. I argue that his realist and antirealist claims are different. For Duhem, scientific reasoning leads straight to antirealism. But intuition (reasons of the heart) motivates, without justifying, a kind of realism. I develop this idea to suggest a motivational realist interpretation of Duhem's philosophy.

Experimental radiobiology represented a long-standing priority for the U.S. Atomic Energy Commission, but organizational issues initially impeded the laboratory progress of this government-funded work: who would direct such interdisciplinary investigations and how? And should the AEC support basic research or only mission-oriented projects? Alexander Hollaender's vision for biology in the post-war world guided AEC initiatives at Oak Ridge, where he created and presided over the Division of Biology for nearly two decades. Hollaender's scheme, at once entrepreneurial and system-oriented, made good (...) use of the unique resources provided by the AEC and by Oak Ridge's national laboratory setting, while at the same time it restructured wartime research practices to better reflect biologists' own priorities. Because Hollaender offered many academic experimental biologists a way of envisioning military-related patronage as integral - rather than antithetical - to their professional identities, his work provides an important lens through which to examine the early post-war intellectual and institutional development of radiobiology.

Current discussion of scientific realism and antirealism often cites Pierre Duhem’s argument for the underdetermination of theory choice by evidence. Participants draw on an account of his underdetermination thesis that is familiar, but incomplete. The purpose of this article is to complete the familiar account. I argue that a closer look at Duhem’s The aim and structure of physical theory suggests that the rationale for his underdetermination thesis comes from his philosophy of scientific language. I explore how an understanding of (...) physical laws as symbolic is meant to support the thesis. In the course of my argument, I point out that Duhemian underdetermination is not meta-practical but grounded in the practice of science, specifically in the scientist’s use of instruments and measurement techniques. Measurement has a significant limitation, according to Duhem: it always involves approximation and a degree of experimental error. Consequently, it cannot overcome the gap between the ordinary, concrete language of observation and the mathematical language of science. Moreover, Duhem argues that the use of instruments in experiment invokes whole groups of theories. I contend that, ultimately, this reliance on auxiliary assumptions—which makes possible the use of instruments—is the foundation of his thesis and that recognizing this completes the familiar account of his underdetermination argument.Author Keywords: Duhem; Suppes; Underdetermination; Measurement; Physical theory.

Self-tracking practices include the use of personal data-gathering apps, wearable devices, and data analysis tools to record patterns from daily activities, as well as the organization, visualization, and analysis of this data. This paper draws on theories of digital labour and feminist political economy to build a framework of digital productive labour that highlights the exploitation of activities external to the formal labour relationship. Self-tracking practices are analysed through the lens of digital productive insofar as they fulfill three roles: they (...) generate the content necessary for sustaining digital networks and producing data that can be captured in commodity form; they aid in the reproduction of the social factory’s labour force; and they cultivate subjectivities amenable to consumption and production in contemporary capitalism. The paper examines the production and commodification of data, highlighting the algorithmic means by which self-trackers are separated from the financial value of their data. This is connected to feminist analyses of unpaid labour, with particular attention to self-tracking’s role as a contemporary form of reproductive labour that replenishes the labour force. Finally, the paper provides an analysis of the themes of self-knowledge, self-discovery, and gamification to understand how these frame self-trackers’ understanding of themselves as labourers, thus reproducing and deepening capitalist subjectivities. The paper concludes by considering self-tracking through the lens of the exploitation of life ‘outside’ the official labour relationship. (shrink)

Certaines ont affirmé que le concept de gender était une invention américaine, intraduisible par le mot français « genre ». Pourtant, au-delà des distinctions grammaticales, il existe depuis longtemps - bien avant Beauvoir, Oakley, et l'usage postmoderniste construit par Joan Scott et Judith Butler - un usage français du terme « genre », qui spécifie dans le vocabulaire sociopolitique - notamment féministe - la construction sociale et culturelle des sexes. L’objet de cet article est d’en rétablir les trajectoires historiques et (...) de contribuer peut-être à balayer les dernières réticences manifestées en France à son égard. (shrink)

The idea of culture has been subject to critical debate in anthropology during the past decade as the result of a shift in emphasis from the bounded local culture to transnational cultural flows. But at the very same time that cultural mobility is being emphasized by anthropologists, the people they study are recasting culture as a place of belonging as they construct local identities. Siting Culture argues that it is only through rich ethnographic studies that anthropologists may explore the significance (...) of place in the global space of relations which mold the lives of people throughout the world. By examining the concept of culture through case studies from Europe, Africa, Oceania, Latin America and the Caribbean, it probes the methodological and theoretical implications of the divergent scholarly and popular concepts of culture.

The general conceit of Schiller’s aesthetic education is that our experiences with art and beauty set us free from internal and external constraints and allow us to embrace our full humanity as rational and sensuous beings. Experiencing the aesthetic, or the play impulse, puts one in a state of aesthetic determinacy—or rather indeterminacy—that Schiller calls the highest sense of freedom, aesthetic freedom. Gail K. Hart examines Anthony Burgess’s A Clockwork Orange as an example of what Schillerian aesthetic education might look (...) like in practice. Though it represents a distortion of Schiller’s aesthetic education, Hart argues that it also reveals an ineradicable element of coercion in aesthetic education. I argue that Burgess’s Ludovico Technique leaves out a key element of Schiller’s conception of aesthetic cultivation—play—and that Hart’s analysis of Schiller’s work likewise lacks a robust analysis of his notion of play. I argue that, when Schiller’s account of the play impulse is taken seriously as a necessary condition for aesthetic cultivation to take place, coercion is by definition made impossible. Aesthetic play is accomplished by the mutual destruction of physical and moral determinations, and this mutual erasure leads to a higher and more expansive freedom. External constraints and coercion cannot induce the aesthetic state, so aesthetic education as Schiller presents it in On the Aesthetic Education of Man cannot contain the element of coercion Hart suspects.

Ninety percent of this (...) group receives their insurance through employer-sponsored programs, and the remaining ten percent buy their own coverage. Approximately ten percent of the non-elderly population has insurance through a government program, and fifteen percent of the non-elderly population, almost forty-one million Americans, is uninsured.

The Court of Justice of the European Union and the way in which it works can be seen as a microcosm of how a multilingual, multicultural supranationalisation process and legal order can be constructed—the Court is a microcosm of the EU as a whole and in particular of EU law. The multilingual jurisprudence produced by the CJEU is necessarily shaped by the dynamics within that institution and by the ‘cultural compromises’ at play in the production process. The resultant texts, which (...) make up that jurisprudence, are hybrid in nature and inherently approximate. On the one hand, that approximation can lead to discrepancies between language versions of the Court’s case law and thus jeopardise the uniform application of EU law. On the other hand, that approximation and hybridity define EU law as a distinct, supranational legal order. This paper analyses the operation of the CJEU and considers whether a linguistic cultural compromise exists within that institution which exercises a formative influence on the character of its ‘output’—i.e. its jurisprudence—and what that may mean for our understanding of the development of EU law.

The welfare mother is a powerful symbol of the supposed irresponsible, sexually promiscuous, and immoral behavior of the poor. Resting on dominant ideologies of race, class, and gender, the welfare mother suggests not a poor mother but a bad mother. Based on interviews with 34 mothers receiving public assistance, this article explores how women receiving assistance claim for themselves an identity as good mothers by defining the appropriate responsibilities of mothers to prioritize, protect, discipline, provide for, and spend time with (...) their children. The material realities of poverty combined with work requirements now attached to public assistance exacerbate contradictions between these roles and create difficulties for these mothers. This article explores these contradictions and examines the possibilities for and limits of their use as resistance strategies. (shrink)

Bauer, Taub, and Parsi's review of an international sample of standards on informed consent, confidentiality, commercialization, and quality of research in tissue banking reveals that no clear national or international consensus exists for these issues. The authors' response to the lack of uniformity in the meaning, scope, and ethical significance of the policies they examined is to call for the creation of uniform ethical guidelines. This raises questions about whether harmonization should consist of voluntary international standards or international regulations that (...) include an official oversight mechanism and sanctions for noncompliance, and about who should participate in the harmonization process. Moreover, the normative assumptions and political dynamics that shape global policymaking need to be addressed. This commentary explores the policy implications and normative questions raised by the idea of international ethical guidelines for the use of biotechnologies and biotechnological resources such as stored samples of human tissue.
