Quantum mechanics tells us that states involving indistinguishable fermions must be antisymmetrized. This is often taken to mean that indistinguishable fermions are always entangled. We consider several notions of entanglement and argue that on the best of them, indistinguishable fermions are not always entangled. We also present a simple but unconventional way of representing fermionic states that allows us to maintain a link between entanglement and non-factorizability.

Potentiality, Entanglement and Passion-at-a-Distance is a book for theoretical physicists and philosophers of modern physics. It treats a puzzling and provocative aspect of recent quantum physics: the apparent interaction of certain physical events that cannot share any causal connection. These are said to be `entangled' in some way, but an explanation remains elusive. Abner Shimony - to whom the book is dedicated - and others suggest the need to revive the category of what may be seen as a metaphysical (...) potentiality. Abner has described these events without actions to link them as `passion at a distance': not active, but passive. The discussions gathered here are written by a truly remarkable cast of scientists and philosophers and shed new light on the most profound puzzles of our times. (shrink)

Rob Clifton was one of the most brilliant and productive researchers in the foundations and philosophy of quantum theory, who died tragically at the age of 38. Jeremy Butterfield and Hans Halvorson collect fourteen of his finest papers here, drawn from the latter part of his career (1995-2002), all of which combine exciting philosophical discussion with rigorous mathematical results. Many of these papers break wholly new ground, either conceptually or technically. Others resolve a vague controversy intoa precise technical problem, which (...) is then solved; still others solve an open problem that had been in the air for soem time. All of them show scientific and philosophical creativity of a high order, genuinely among the very best work in the field. The papers are grouped into four Parts. First come four papers about the modal interpretation of quantum mechanics. Part II comprises three papers on the foundations of algebraic quantum field theory, with an emphasis on entanglement and nonlocality. The two papers in Part III concern the concept of a particle in relativistic quantum theories. One paper analyses localization; the other analyses the Unruh effect (Rindler quanta) using the algebraic approach to quantum theory. Finally, Part IV contains striking new results about such central issues as complementarity, Bohr's reply to the EPR argument, and no hidden variables theorems; and ends with a philosophical survey of the field of quantum information. The volume includes a full bibliography of Clifton's publications. Quantum Entanglements offers inspiration and substantial reward to graduates and professionals in the foundations of physics, with a background in philosophy, physics, or mathematics. (shrink)

David Lewis is a natural target for those who believe that findings in quantum physics threaten the tenability of traditional metaphysical reductionism. Such philosophers point to allegedly holistic entities they take both to be the subjects of some claims of quantum mechanics and to be incompatible with Lewisian metaphysics. According to one popular argument, the non-separability argument from quantum entanglement, any realist interpretation of quantum theory is straightforwardly inconsistent with the reductive conviction that the complete physical state of the (...) world supervenes on the intrinsic properties of and spatio-temporal relations between its point-sized constituents. Here I defend Lewis's metaphysical doctrine, and traditional reductionism more generally, against this alleged threat from quantum holism. After presenting the non-separability argument from entanglement, I show that Bohmian mechanics, an interpretation of quantum mechanics explicitly recognized as a realist one by proponents of the non-separability argument, plausibly rejects a key premise of that argument. Another holistic worry for Humeanism persists, however, the trouble being the apparently holistic character of the Bohmian pilot wave. I present a Humean strategy for addressing the holistic threat from the pilot wave by drawing on resources from the Humean best system account of laws. (shrink)

This paper develops and explores the idea of moral entanglements: the ways in which, through innocent transactions with others, we can unintendedly accrue special obligations to them. More particularly, the paper explains intimacy-based moral entanglements, to which we become liable by accepting another's waiver of privacy rights. Sometimes, having entered into others' private affairs for innocent or even helpful reasons, one discovers needs of theirs that then become the focus of special duties of care. The general duty to warn them (...) of their need cannot directly account for the full extent of these duties, but does indicate why a silent retreat is impermissible. The special duties of care importantly rest on a transfer of responsibilities that accompanies the privacy waivers. The result is a special obligation of beneficence that, while grounded in a voluntary transaction, was never voluntarily undertaken. Impartialist views of beneficence cannot capture the relevant phenomena well. (shrink)

Initially Einstein, Podolsky, and Rosen (EPR) and later Bell shed light on the non-local properties exhibited by subsystems in quantum mechanics. Separately, Kochen and Specker analyzed sets of measurements of compatible observables and found that a consistent coexistence of these results is impossible, i.e., quantum indefiniteness of measurement results. As a consequence, quantum contextuality, a more general concept compared to non-locality, leads to striking phenomena predicted by quantum theory. Here, we report neutron interferometric experiments which investigate entangled states in a (...) single-particle system: entanglement is, in this case, achieved not between particles, but between degrees of freedom i.e., between spin, path, and energy degrees of freedom. Appropriate combinations of the spin analysis and the position of the phase shifter in the interferometer allow an experimental verification of the violation of a Bell-like inequality. In addition, state tomography, tomographic analysis of the density matrix of a quantum system, and Kochen-Specker-like phenomena are presented to characterize neutrons’ entangled states and their peculiarity. Furthermore, a coherent energy manipulation scheme is accomplished with a radio-frequency (RF) spin-flipper. This scheme allows the (total) energy degree of freedom to be entangled: the remarkable behavior of a triply entangled GHZ-like state is demonstrated. (shrink)

Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyse entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter's (...) ability to perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard non-relativistic quantum theory and classical relativistic field theory.

We consider the concept of entanglement for pure cases of finite dimensional state spaces. The criterion of unentangled states is related to demanding rank one of an associated eigenvalue problem. In addition to the conventional procedure based on the Schmidt decomposition, we devise a method based on the spectral resolution of unsymmetric matrices. In particular, we consider the case when all eigenvalues are zero, and find that the method still works.

Squashed entanglement :829–840, 2004) is a monogamous entanglement measure, which implies that highly extendible states have small value of the squashed entanglement. Here, invoking a recent inequality for the quantum conditional mutual information :575–611, 2015) greatly extended and simplified in various work since, we show the converse, that a small value of squashed entanglement implies that the state is close to a highly extendible state. As a corollary, we establish an alternative proof of the faithfulness of (...) squashed entanglement. We briefly discuss the previous and subsequent history of the Fawzi–Renner bound and related conjectures, and close by advertising a potentially far-reaching generalization to universal and functorial recovery maps for the monotonicity of the relative entropy.

In this paper recent work that attempts to link quantum entanglement to (i) thermodynamic energy, (ii) thermodynamic entropy and (iii) information is reviewed. With respect to the first two links the paper is essentially expository. The final link is elaborated on: it is argued that the value of the entanglement of a bipartite system in a pure state is equal to the value of the irreducible uncertainty (i.e. irreducibly missing information) about its subsystems and that this suggests that (...) entanglement gives rise to irreducible uncertainty. (The exact meaning of the phrase “irreducible uncertainty”, as used here, is explained in the body of the paper. Roughly speaking, it is the uncertainty about the post-measurement state of a system that cannot be removed at the pre-measurement stage.) This analysis is used to make a further connection between entanglement and statistical mechanical entropy: it is argued that these properties are indirectly linked, in so far as both give rise to forms of uncertainty (albeit rather different forms of uncertainty about rather different things). (shrink)

This paper argues for a metaphysics of relations based on a characterization of quantum entanglement in terms of non-separability, thereby regarding entanglement as a sort of holism. By contrast to a radical metaphysics of relations, the position set out in this paper recognizes things that stand in the relations, but claims that, as far as the relations are concerned, there is no need for these things to have qualitative intrinsic properties underlying the relations. This position thus opposes a (...) metaphysics of individual things that are characterized by intrinsic properties. A principal problem of the latter position is that it seems that we cannot gain any knowledge of these properties insofar as they are intrinsic. Against this background, the rationale behind a metaphysics of relations is to avoid a gap between epistemology and metaphysics. (shrink)

This chapter contains sections titled: Subjection and Autonomy: Foucault contra Habermas What Is Fallacious About the Genetic Fallacy? Conclusion References.

Distance, it is often argued, is the only coherent and empirically adequate world-making relation that can glue together the elements of the world. This paper offers entanglement as an alternative world-making relation. Entanglement is interesting since it is consistent even with quantum gravity theories that do not feature space at the fundamental level. The paper thereby defends the metaphysical salience of such non-spatial theories. An account of distance is the predominant problem of empirical adequacy facing entanglement as (...) a world-making relation. A resolution of this obstacle utilizes insights from the Ryu–Takayanagi formula and Susskind and Maldacena’s related ER = EPR conjecture. Together these indicate how distance can be recovered from entanglement and thus carves the way for entanglement fundamentalism. (shrink)

The relativistic three-particle systems are studied within the framework of Relativistic Schrödinger Theory, with emphasis on the determination of the energy functional for the stationary bound states. The phenomenon of entanglement shows up here in form of the exchange energy which is a significant part of the relativistic field energy. The electromagnetic interactions become unified with the exchange interactions into a relativistic U gauge theory, which has the Hartree–Fock equations as its non-relativistic limit. This yields a general framework for (...) treating entangled states of relativistic many-particle systems, e.g., the N-electron atoms. (shrink)

Experiments involving delayed-choice entanglement swapping seem to suggest that particles can become entangled after they’ve already been detected. This astonishing result is taken by some to undermine realism about entanglement. In this paper, I argue that one can offer a fully realist explanation of delayed-choice entanglement swapping by countenancing timelike entanglement relations. I argue that such an explanation—radical though it may be—isn’t incoherent and doesn’t invite paradox. I compare this approach to the antirealist alternative and a (...) more deflationary realist strategy defended by Egg, each of which face certain challenges. The upshot is that we should take seriously the possibility of timelike entanglement and seek to develop a framework for quantum theory which allows for it. (shrink)

We explore the entanglement of the vacuum of a relativistic field by letting a pair of causally disconnected probes interact with the field. We find that, even when the probes are initially non-entangled, they can wind up to a final entangled state. This shows that entanglement persists between disconnected regions in the vacuum. However the probe entanglement, unlike correlations, vanishes once the regions become sufficiently separated. The relation between entropy, correlations and entanglement is discussed.

This paper surveys some of the questions that arise when we consider how entanglement and relativity are related via the notion of non-locality. We begin by reviewing the role of entangled states in Bell inequality violation and question whether the associated notions of non-locality lead to problems with relativity. The use of entanglement and wavefunction collapse in Einstein's famous incompleteness argument is then considered, before we go on to see how the issue of non-locality is transformed if one (...) considers quantum mechanics without collapse to be a complete theory, as in the Everett interpretation.

Quantum mechanical entangled configurations of particles that do not satisfy Bell’s inequalities, or equivalently, do not have a joint probability distribution, are familiar in the foundational literature of quantum mechanics. Nonexistence of a joint probability measure for the correlations predicted by quantum mechanics is itself equivalent to the nonexistence of local hidden variables that account for the correlations (for a proof of this equivalence, see Suppes and Zanotti, 1981). From a philosophical standpoint it is natural to ask what sort of (...) concept can be used to provide a “joint” analysis of such quantum correlations. In other areas of application of probability, similar but different problems arise. A typical example is the introduction of upper and lower probabilities in the theory of belief. A person may feel uncomfortable assigning a precise probability to the occurrence of rain tomorrow, but feel comfortable saying the probability should be greater than ½ and less than ⅞. Rather extensive statistical developments have occurred for this framework. A thorough treatment can be found in Walley (1991) and an earlier measurement-oriented development in Suppes (1974). It is important to note that this focus on beliefs, or related Bayesian ideas, is not concerned, as we are here, with the nonexistence of joint probability distributions. Yet earlier work with no relation to quantum mechanics, but focused on conditions for existence has been published by many people. For some of our own work on this topic, see Suppes and Zanotti (1989). Still, this earlier work naturally suggested the question of whether or not upper and lower measures could be used in quantum mechanics, as a generalization of.. (shrink)

In this paper, it is argued that Aristotelian hylomorphism can supply a useful and informative account of composite entities as these are described by physical theory. In particular, a hylomorphic account of quantum entangled systems is defined in detail, and compared to other alternatives currently on offer—in particular, ontic structural realism. In closing, it is suggested that the view of entanglement outlined here meshes well with a recently proposed ‘coherentist’ conception.

The characteristic holistic features of the quantum theoretic formalism and the intriguing notion of entanglement can be applied to a field that is far from microphysics: logical semantics. Quantum computational logics are new forms of quantum logic that have been suggested by the theory of quantum logical gates in quantum computation. In the standard semantics of these logics, sentences denote quantum information quantities: systems of qubits (quregisters) or, more generally, mixtures of quregisters (qumixes), while logical connectives are interpreted as (...) special quantum logical gates (which have a characteristic reversible and dynamic behavior). In this framework, states of knowledge may be entangled, in such a way that our information about the whole determines our information about the parts; and the procedure cannot be, generally, inverted. In spite of its appealing properties, the standard version of the quantum computational semantics is strongly “Hilbert-space dependent”. This certainly represents a shortcoming for all applications, where real and complex numbers do not generally play any significant role (as happens, for instance, in the case of natural and of artistic languages). We propose an abstract version of quantum computational semantics, where abstract qumixes, quregisters and registers are identified with some special objects (not necessarily living in a Hilbert space), while gates are reversible functions that transform qumixes into qumixes. In this framework, one can give an abstract definition of the notions of superposition and of entangled pieces of information, quite independently of any numerical values. We investigate three different forms of abstract holistic quantum computational logic. (shrink)

The purpose of the article is to elaborate on the scholarly debate on affect. We consider the site of affect to be the activities of embodied, socioculturally and spatially situated participants: “Affective activity is a form of social practice” (Wetherell, 2015, p. 147). By studying affect as a social phenomenon, we treat affect as a social ontology. Social practices are constituted through participation in social interaction, which makes it possible to study affect empirically. Moreover, we suggest that to consider affect (...) a social ontology connects affect to agency. We regard affect as a participants’ phenomenon where emotions and knowledge are not separated, i.e. as a social epistemology. To capture the complexity of affective activity, the study of situated participation requires video data. We collected data at a centre for persons with acquired brain injury (ABI), which highlights research ethics. The International Classification of Functioning, Disability and Health (ICF) framework defines participation as involvement in life situations. ICF focuses on two broader perspectives: the body and the individual in society. We turn ICF’s abstract societal perspective on participation to meaningful local accomplishments in lived social practices. Our focus is, in line with a critical social ontology in disability studies, on how-ability, the communicative abilities of the residents (Hughes, 2007). To get closer to life situations as they unfold, we analyse participation in its details as embodied actions during activities in the material environment of the centre. To conclude, we demonstrate a resident’s competent participation in an occupational therapy session through a fine-grained analysis of affective activity. Interaction, practices and phenomena are complex theoretical and practical issues. In the analysis of the encounters as complex multimodal and -sensorial situations, we use an extended version of Ethnomethodological Conversation Analysis (EMCA) that incorporates the body and material environment with the interconnectedness of interactional episodes. To do this, we enlarge the scope of analysis from the complexity of local occasions of affective activity to connections between consecutive affective entanglements. In the indicated work we draw on theoretical (lamination) and methodological (nexus analysis) suggestions in order to best pursue the sociocultural nature of situated interactions. (shrink)

Using a single spin-1 object as an example, we discuss a recent approach to quantum entanglement. [A.A. Klyachko and A.S. Shumovsky, J. Phys: Conf. Series 36, 87 (2006), E-print quant-ph/0512213]. The key idea of the approach consists in presetting of basic observables in the very definition of quantum system. Specification of basic observables defines the dynamic symmetry of the system. Entangled states of the system are then interpreted as states with maximal amount of uncertainty of all basic observables. The (...) approach gives purely physical picture of entanglement. In particular, it separates principle physical properties of entanglement from inessential. Within the model example under consideration, we show relativity of entanglement with respect to dynamic symmetry and argue existence of single-particle entanglement. A number of physical examples are considered. (shrink)

The study of ancient DNA has gained increasing attention in science and society as a tool for tracing hominin evolution. While aDNA research overlaps with the history of population genetics, it embodies a specific configuration of technology, temporality, temperature, and place that, this article suggests, cannot be fully unpacked with existing science and technology studies approaches to population genetics. This article explores this configuration through the 2010 discovery of the Denisovan hominin based on aDNA retrieved from a finger bone and (...) tooth in Siberia. The analysis explores how the Denisovan was enacted as a technoscientific object through the cool and even temperatures of Denisova Cave, assumptions about the connection between individual and population, the status of populations as evolutionary entities, and underlying colonialist and imperialist imaginaries of Siberia and Melanesia. The analysis sheds light on how aDNA research is changing the parameters within which evolutionary history is imagined and conceptualized. Through the case study, it also outlines some ways in which the specific technoscientific and cultural entanglements of aDNA can be critically explored. (shrink)

The purpose of this short article is to build on the work of Ghirardi, Marinatto and Weber and Ladyman, Linnebo and Bigaj, in supporting a redefinition of en- tanglement for “indistinguishable” systems, particularly fermions. According to the proposal, non-separability of the joint state is insufficient for entanglement. The re- definition is justified by its physical significance, as enshrined in three biconditionals whose analogues hold of “distinguishable” systems.

Law is usually understood as an orderly, coherent system, but this volume shows that it is often better understood as an entangled web. Bringing together eminent contributors from law, political science, sociology, anthropology, history and political theory, it also suggests that entanglement has been characteristic of law for much of its history. The book shifts the focus to the ways in which actors create connections and distance between different legalities in domestic, transnational and international law. It examines a wide (...) range of issue areas, from the relationship of state and indigenous orders to the regulation of global financial markets, from corporate social responsibility to struggles over human rights. The book uses these empirical insights to inform new theoretical approaches to law, and by placing the entanglements between norms from different origins at the centre of the study of law, it opens up new avenues for future legal research. This title is also available as Open Access. (shrink)

This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a quantum handshake between normal and time-reversed waves, this model provides a clear visual picture explaining the baffling experimental results (...) that flow daily from the quantum physics laboratories of the world. To demonstrate its powerful simplicity, the transactional model is applied to a collection of counter-intuitive experiments and conceptual problems. (shrink)

The idea of entangled modernities is best understood as a complement and corrective to that of `multiple modernities': it serves to theorize the global unity and interconnections of modern socio-cultural formations in a non-reductionist and non-functionalist way. But it can also help to highlight complexity and divergence behind the outwardly uniform or parallel patterns of development. This line of thought seems particularly relevant to the history of Communism. The interdependent but divergent trajectories of the two imperial revolutions, Russian and Chinese, (...) exemplify the multiple patterns of entanglement in unusually instructive ways. In both cases, imperial legacies and traditions interacted with modernizing imperatives and geopolitical constraints, as well as with the revolutionary projects proposed as solutions to the imperial crises. The Sino-Soviet entanglement was highly asymmetric; although the Chinese connection seems to have been important at several critical junctures in Soviet history, the impact of the Soviet model on Chinese Communism was incomparably more formative. But the Chinese metamorphoses of the Soviet model deviated from the original in various ways; they were too complex and sometimes too self-destructive to be explained in terms of an adaptive logic. Rather, the transfigurations that took place at various stages - from the beginnings of Chinese Bolshevism to the aberrations of Maoism in power - can be understood as changing patterns of entanglement, combining radicalizing twists to the Soviet model with selective reactivation of Chinese traditions.

This paper explores some of the consequences of quantum entanglement for the mainstream metaphysician. The basic idea that entanglement has metaphysical consequences in the form of some kind of “holism” is familiar in the philosophy of physics literature, and finds its way into recent metaphysics, in discussions of failure of Humean supervenience, monism and emergence, for example. The principle aim here is to highlight some questions of detail that occur when attempting to make contact with those metaphysical debates (...) as they occur in the metaphysics literature-details that matter less when the aim is just to show that there is some novelty in entanglement, but more when articulating its precise nature. The conclusion is broadly that the differences are not as great as is sometimes supposed between entanglement and more familiar phenomena already accommodated in prominent metaphysical schemes.

Quantum entanglement is a key resource, which grants quantum systems the ability to accomplish tasks that are classically impossible. Here, we apply Feynman's sum-over-histories formalism to interacting bipartite quantum systems and introduce entanglement measures for bipartite quantum histories. Based on the Schmidt decomposition of the matrix comprised of the Feynman propagator complex coefficients, we prove that bipartite quantum histories are entangled if and only if the Schmidt rank of this matrix is larger than 1. The proposed approach highlights (...) the utility of using a separable basis for constructing the bipartite quantum histories and allows for quantification of their entanglement from the complete set of experimentally measured sequential weak values. We then illustrate the nonclassical nature of entangled histories with the use of Hardy's overlapping interferometers and explain why local hidden variable theories are unable to correctly reproduce all observable quantum outcomes. Our theoretical results elucidate how the composite tensor product structure of multipartite quantum systems is naturally extended across time and clarify the difference between quantum histories viewed as projection operators in the history Hilbert space and those viewed as chain operators and propagators in the standard Hilbert space.

We argue that in implanted neurotechnology research, participants and researchers experience what Henry Richardson has called “moral entanglement.” Participants partially entrust researchers with access to their brains and thus to information that would otherwise be private, leading to created intimacies and special obligations of beneficence for researchers and research funding agencies. One of these obligations, we argue, is about continued access to beneficial technology once a trial ends. We make the case for moral entanglement in this context through (...) exploration of participants’ vulnerability, uncompensated risks and burdens, depth of relationship with the research team, and dependence on researchers in implanted neurotechnology trials.

Violations of the Bell inequalities in EPR-Bohm type experiments have set the literature on the metaphysics of microscopic systems to flirting with some sort of metaphysical holism regarding spatially separated, entangled systems. The rationale for this behavior comes in two parts. The first part relies on the proof, due to Jon Jarrett [2] that the experimentally observed violations of the Bell inequalities entail violations of the conjunction of two probabilistic constraints. Jarrett called these two constraints locality and completeness. We prefer (...) the terminology of locality and factorizability.[3] The first part of the rationale for metaphysical holism urges that only Jarrett’s locality allows for “peaceful coexistence” between any model of EPR-Bohm type experiments and special relativity. Factorizability, it is suggested, must be jettisoned. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Entanglement: How Art and Philosophy Make Us What We Are by Alva NoëFrederik M. Bjerregaard-NielsenNOË, Alva. The Entanglement: How Art and Philosophy Make Us What We Are. Princeton, N.J.: Princeton University Press, 2023. 288 pp. Cloth, $27.95In The Entanglement, Alva Noë sets forth a minimal yet meaningful definition of art and philosophy and asks how they make us what we are. Art and philosophy (...) are the modes of practice that disrupt and disorganize our habitual ways of doing things, everything from dancing to language, to philosophy and art themselves. They are the reflection at a distance of what we do. “In this sense, then, art is disruptive. Always: everywhere.” From this basis, he tackles a wide range of phenomena from dancing, seeing, writing, and so forth, to introduce a distinction between these as everyday phenomena and their function as art. This delimitation is not material, nor intrinsic to any of the analyzed phenomena; rather, it depends on each practice’s ability to disrupt, disorganize, and force upon us the question of what dancing, seeing, writing is at all. Noë provides an example: At an art exhibition one is confronted with a painting that is ungraspable, foreign, meaningless. But, through a mediation (pointers from a friend, new knowledge of the era, analyses of the style, and so forth) the painting starts becoming significant; it starts to make sense. The viewer is stopped in her tracks, and a painting that was before closed is now opened up to a new perception, a new way of seeing.But Noë extends this aesthetic domain to experience and perception. In perception, we are actively engaged in achieving the things around us, achieving the world. And, in art, this habitual way of attainment is obstructed, for art presents us with new ways of seeing, listening, feeling, and so forth. Noë thus challenges common (especially neuro-aesthetic) views on perception and experience in favor of a more phenomenological approach by which he accentuates the active engagement in the world by which perception and experience come about. And this aesthetic domain, broadly understood, is the locus of showing how we, through these disruptive practices, create new ways of doing, perceiving, understanding, and, even further, create ourselves. We “all operate in a space of significance held open by art.” In other words, it is through a reassessment of the aesthetic that Noë shows how art and philosophy make us what we are. For what we are, for Noë, is this ability of disruption, development, and creation of ourselves. This is what makes us human. Human nature is therefore essentially cultural, a disruption of habit and new avenues of development, but one that is rooted in our body as a horizon of possibilities. Even though he does not conclude on this phylogenetic question, Noë does seem to suggest that the species’s ability to generate art (exemplified by early cave paintings) and philosophy are foundational [End Page 724] to its development or, more strongly, necessary to it being what it is. He thus proposes an alternative to the traditional schism of the nature/nurture and natural/cultural debate, which takes this wide view of aesthetics as its central term.One might raise the question whether the text would have benefited from more thorough analyses of the thinkers who are at play, sometimes at the margin, sometimes at the foundation of the disruption Noë’s text attempts, notably: Merleau-Ponty, with his extensive analyses of habit and style and their place in our life engaging behavior; Derrida’s deconstruction of phonocentrism, which attacks written language’s subordination to the spoken and asks the fundamental question of the ontology of language as such; or perhaps most present by its absence, Nietzsche’s grandiose thought of the human being and life itself as an aesthetic phenomenon. For Nietzsche thereby incorporated both ontology and critique in the sphere of aesthetics in his revaluation of all values. This, quite like Noë, allowed Nietzsche to set forth the human being as a creature of its own creation. These authors are given brief treatments, relegated to footnotes, or left out entirely.But such a critique might be too... (shrink)

This paper explains the phenomenon of `entanglement exchange' within the Bohmian approach to quantum mechanics. After explaining Bohmian mechanics and entanglement exchange, in which pairs of particles become entangled without ever interacting causally in the usual, unitary sense, our aim is to use this example, to illustrate how the `pilot wave' mediates non-local correlations. The discussion thus gives a useful new way to think about entanglement exchange, and clarifies the structure of Bohmian mechanics.

This paper outlines key applications of property rights theory from the standpoint of ‘entangled political economy,’ which conceptualises economic and political agents interacting within society. The entangled political economy framework stresses that property rights denote relationships between societal members, and that property rights are the subject of evolutionary change. The nature and role of property rights in an entangled political economy reinforces the ‘bundle of rights’ perspective, challenging notions of property rights that emphasise the primacy of ownership. Far from necessarily (...) imperilling the integrity of a market-based economic order, the bundle orientation inherent in entangled political economy can accommodate extensive market activities grounded in robust property right protections.

Food and life are intimately entangled. To grasp the underlying complexity of this seemingly simple statement, this article first introduces the approach to food/eating as an assemblage enacted by various heterogeneous components, and further develops it by engaging with actor network theory and material semiotics. Thereafter the focus turns to ‘entanglement’, as inspired by quantum physics, to elicit the basic dynamics of the entanglement of food and more-than-human beings, conceived of as involving mutual and differential becomings within and (...) among assemblages. The article illustrates these entangled becomings by drawing upon examples from Sri Lanka, which in an intercultural philosophical fashion serve to establish an articulation (in the sense of a connection) between the proposed abstract approach to food and some basic premises of Buddhism and Ayurveda, a South Asian health system. Overall, the article crafts a conceptual toolbox and performs ontological groundwork wherein food and human beings as entangled assemblages provide a productive, refined, and sensitive research apparatus for the intimate study of more-than-human life and organization while also spurring novel theorizations through food/eating.

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.

The path integral is not typically utilized for analyzing entanglement experiments, in part because there is no standard toolbox for converting an arbitrary experiment into a form allowing a simple sum-over-history calculation. After completing the last portion of this toolbox (a technique for implementing multi-particle measurements in an entangled basis), some interesting 4- and 6-particle experiments are analyzed with this alternate technique. While the joint probabilities of measurement outcomes are always equivalent to conventional quantum mechanics, differences in the calculations (...) motivate a number of foundational insights, concerning nonlocality, retrocausality, and the objectivity of entanglement itself.

When a quantum system is macroscopic and becomes entangled with a microscopic one, entanglement is not immediately total, but gradual and local. A study of this locality is the starting point of the present work and shows unexpected and detailed properties in the generation and propagation of entanglement between a measuring apparatus and a microscopic measured system. Of special importance is the propagation of entanglement in nonlinear waves with a finite velocity. When applied to the entanglement (...) between a macroscopic system and its environment, this study yields also new results about the resulting disordered state. Finally, a mechanism of wave function collapse is proposed as an effect of perturbation in the growth of local entanglement between a measuring system and the measured one by waves of entanglement with the environment.

It is not uncommon these days to claim that we should distinguish between artistic value and other types of value, including aesthetic value. A problem for this proposal is posed by the fact that artworks have valuable properties that are no part of its artistic value. Unless there is a way to distinguish artistically valuable properties from other valuable properties, some will be unconvinced that the distinction is viable.1 For this reason, I have proposed a test for artistic value to (...) underwrite support for the distinction.2 The main idea of the test is that we gain access to artistic values of artworks by means of understanding or appreciating those works, and this is not necessary to identify a work’s non-artistic values. Julian Dodd has argued the test is flawed and his criticism is based on a phenomenon I will call value entanglement.3 In this paper, I will identify the interesting phenomena of value entanglement, argue that it does not threaten the current version of the test I endorse, and explore whether there are other problems for that test.

Modernity is better defined as a time orientation, instead of as a set of institutions, which usually smuggles in some provincial or other aprioristic assumptions. A time conception of modernity also gives a precise meaning to postmodernity. Modernity in this non-Eurocentric sense, entails several different, competing master narratives, different social forces of, and conflicts between, modernity and anti-modernity, and different cultural contextualizations of the past-future contrast. But these different varieties do not simply coexist and challenge each other, they are entangled (...) with each other in various ways. Starting from observing how different time warps were interwoven in vanguard modernist art, an analytical framework for grasping, understanding, and explaining the entanglement of modernities is spelled out.

In this essay, I explore the founding violence that the Royal Danish Academy of Fine Arts can be said to rest on. I propose to view the building of Charlottenborg Castle which houses the Royal Danish Academy of Fine Arts as a “material witness” (Schuppli) to colonial history. I suggest that the building forms part of a material “cultural archive” (Wekker) of colonialism that can be seen as an entangled archive, that is simultaneously an entanglement of overlapping histories, and (...) an instrument that disentangled and disconnected communities affected by colonialism by producing a radical cut between the colonized communities and their creative expression. By juxtaposing paintings from the colonial era with contemporary art works the essay explores the following questions: What does it mean to conduct art education on such contested grounds? What are the ramifications of colonial-modernity within the art institutions today? And how does it continue (indirectly or directly) to distribute and determine what counts as a work of art and who counts as a subject? (shrink)

ABSTRACT Dance and music serve in this essay to exemplify both the looping entanglement of art and life as well as the account of art and philosophy developed in Strange Tools. This essay replies to criticisms of Carrie Noland, Nancy S. Struever, and Thomas Rickert and also offers a briefer restatement of the general approach.

This volume gathers together ground-breaking work on the foundations and philosophy of quantum physics, by one of the most brilliant and productive researchers in the field. Rob Clifton died tragically in 2002 at the age of 38; two of his colleagues, themselves leading philosophers of physics, present fourteen of his finest papers here, all of which combine exciting philosophical discussion with rigorous mathematical results. Quantum Entanglements offers inspiration and substantial reward to anyone working on the foundations of quantum theory, with (...) backgrounds in philosophy, physics, or mathematics. (shrink)
