This article aims to contribute to the ongoing task of clarifying the relationships between reality, probability, and nonlocality in quantum physics. It is in part stimulated by Khrennikov’s argument, in several communications, for “eliminating the issue of quantum nonlocality” from the analysis of quantum entanglement. I argue, however, that the question may not be that of eliminating but instead that of further illuminating this issue, a task that can be pursued by relating quantum nonlocality to other key features of quantum (...) phenomena. I suggest that the following features of quantum phenomena and quantum mechanics, distinguishing them from classical phenomena and classical physics— the irreducible role of measuring instruments in defining quantum phenomena, discreteness, complementarity, entanglement, quantum nonlocality, and the irreducibly probabilistic nature of quantum predictions—are all interconnected, so that it is difficult to give an unconditional priority to any one of them. To argue this case, I shall consider quantum phenomena and quantum mechanics from a nonrealist or, in terms adopted here, “reality-without-realism” perspective. This perspective extends Bohr’s view, grounded in his analysis of the irreducible role of measuring instruments in the constitution of quantum phenomena. (shrink)

This article considers the relationships between the character of physical law in quantum theory and Bohr’s concept of complementarity, under the assumption of the unrepresentable and possibly inconceivable nature of quantum objects and processes, an assumption that may be seen as the most radical departure from realism currently available. Complementarity, the article argues, is a reflection of the fact that, as against classical physics or relativity, the behavior of quantum objects of the same type, say, all electrons, is not governed (...) by the same physical law in all contexts, specifically in complementary contexts. On the other hand, the mathematical formalism of quantum mechanics offers correct probabilistic or statistical predictions in all contexts, here, again, under the assumption that quantum objects themselves and their behavior are beyond representation or even conception. Bohr, in this connection, spoke of “an entirely new situation as regards the description of physical phenomena that, the notion of complementarity aims at characterizing.” The article also considers the relationships among complementarity, entanglement, and quantum information, by basing these relationships on this understanding of complementarity.

Building on Peres’ idea of “Delayed-choice for entanglement swapping” we show that even the degree to which quantum systems were entangled can be defined after they have been registered and may even not exist any more. This does not arise as a paradox if the quantum state is viewed as just a representative of information. Moreover such a view gives a natural quantification of the complementarity between the measure of information about the input state for teleportation and the amount of (...) entanglement of the resulting swapped entangled state.

The concepts of complementarity and entanglement are considered with respect to their significance in and beyond physics. A formally generalized, weak version of quantum theory, more general than ordinary quantum theory of physical systems, is outlined and tentatively applied to two examples.

Presentations of black hole complementarity by van Dongen and de Haro, as well as by 't Hooft, suffer from a mistaken claim that interactions between matter falling into a black hole and the emitted Hawking-like radiation should lead to a failure of commutativity between space-like-related observables localized inside and outside the black hole. I show that this conclusion is not supported by our standard understanding of quantum interactions. We have no reason to believe that near-horizon interactions will (...) threaten microcausality. If these interactions reliably transfer information to the outgoing radiation, then this response to Hawking's information loss argument should amount to a version of the bleaching scenario. I argue that the challenge facing black hole complementarity is that of reconciling this commitment to bleaching with the expectation that the event horizon will be locally unremarkable. This challenge is most promisingly met by proposals that postulate a consistent account of the limitations of our local semi-classical theories, but no support is added to these postulates by appeals to verificationism or to the interactions considered by 't Hooft.

The mental system of an individual usually generates a reality-model that includes a self-model and a world-model as fundamental components. Exceptional experiences (ExE) can be classified as subjectively experienced anomalies in the self-model or the world-model or in the relation of both. Empirical studies show significant correlations between specific patterns of ExE and socially and clinically relevant variables. In order to examine the ontological status of anomalous phenomena a psychophysical approach is presented in which the principle of complementarity is of (...) fundamental importance. Applying a generalized quantum theory to psychosocial and psychophysical systems, complementary aspects such as autonomy versus reliability or novelty versus confirmation are identified as possible local and global variables. The findings indicate that entanglement correlations could play a role in the occurrence of ExE and that specific psychological interventions can dissolve them. (shrink)

The term complementarity plays a central role in quantum physics, not least in various approaches to defining entanglement and the conditions for its occurrence. It has, however, been used in a variety of ways by different authors, denoting different concepts and relationships. Here we describe and clarify some of them and analyze the role they play with respect to the phenomenon of entanglement. Based on these considerations we discuss the recently proposed system-theoretical generalization of the concepts entanglement and complementarity (Atmanspacher (...) et al. in Found Phys 32(3):379–406, 2002; von Lucadou et al. in J Conscious Stud 14(4):50–74, 2007; Filk and Römer in Axiomathes 21(2):211–220, 2011; Walach and Von Stillfried in Axiomathes 21(2): 185–209, 2011). We hope that a clarification regarding the specific meaning of these terms can be useful to the growing engagement with this interesting hypothesis and its critical investigation. (shrink)

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)

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)

A coherent account of the connections and contrasts between the principles of complementarity and uncertainty is developed starting from a survey of the various formalizations of these principles. The conceptual analysis is illustrated by means of a set of experimental schemes based on Mach-Zehnder interferometry. In particular, path detection via entanglement with a probe system and (quantitative) quantum erasure are exhibited to constitute instances of joint unsharp measurements of complementary pairs of physical quantities, path and interference observables. The analysis uses (...) the representation of observables as positive-operator-valued measures (POVMs). The reconciliation of complementary experimental options in the sense of simultaneous unsharp preparations and measurements is expressed in terms of uncertainty relations of different kinds. The feature of complementarity, manifest in the present examples in the mutual exclusivity of path detection and interference observation, is recovered as a limit case from the appropriate uncertainty relation. It is noted that the complementarity and uncertainty principles are neither completely logically independent nor logical consequences of one another. Since entanglement is an instance of the uncertainty of quantum properties (of compound systems), it is moot to play out uncertainty and entanglement against each other as possible mechanisms enforcing complementarity.

The polemical term “interaction-free measurement” (IFM) is analyzed in its interpretative nature. Two seminal works proposing the term are revisited and their underlying interpretations are assessed. The role played by nonlocal quantum correlations (entanglement) is formally discussed and some controversial conceptions in the original treatments are identified. As a result the term IFM is shown to be consistent neither with the standard interpretation of quantum mechanics nor with the lessons provided by the EPR debate.

Despite the burgeoning interest in new and more complex accounts of the organism-environment dyad by biologists and philosophers, little attention has been paid in the resulting discussions to the history of these ideas and to their deployment in disciplines outside biology—especially in the social sciences. Even in biology and philosophy, there is a lack of detailed conceptual models of the organism-environment relationship. This volume is designed to fill these lacunae by providing the first multidisciplinary discussion of the topic of organism-environment (...) interaction. It brings together scholars from history, philosophy, psychology, anthropology, medicine, and biology to discuss the common focus of their work: entangled life, or the complex interaction of organisms and environments.

In this chapter, I propose a new framework for extended epistemology, based on a second-wave approach to extended cognition. The framework is inclusive, in that it takes into account the complex interplay between the diverse embodiments of extended knowers and the salient properties of technological artifacts, as well as the environment in which they are embedded. Thus it both emphasizes and exploits the complementary roles played by these different elements. Finally, I motivate and explain this framework by applying it to (...) a case of interaction with contemporary technologies. (shrink)

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)

A growing number of commentators have, in recent years, noted the important affinities in the views of Immanuel Kant and Niels Bohr. While these commentators are correct, the picture they present of the connections between Bohr and Kant is painted in broad strokes; it is open to the criticism that these affinities are merely superficial. In this essay, I provide a closer, structural, analysis of both Bohr's and Kant's views that makes these connections more explicit. In particular, I demonstrate the (...) similarities between Bohr's argument, on the one hand, that neither the wave nor the particle description of atomic phenomena pick out an object in the ordinary sense of the word, and Kant's requirement, on the other hand, that both ‘mathematical’ (having to do with magnitude) and ‘dynamical’ (having to do with an object's interaction with other objects) principles must be applicable to appearances in order for us to determine them as objects of experience. I argue that Bohr's ‘complementarity interpretation’ of quantum mechanics, which views atomic objects as idealizations, and which licenses the repeal of the principle of causality for the domain of atomic physics, is perfectly compatible with, and indeed follows naturally from a broadly Kantian epistemological framework.

Two quantum Macro-states and their Macroscopic Quantum Superpositions (MQS) localized in two far apart, space-like separated sites can be non-locally correlated by any entangled couple of single-particles having interacted in the past. This novel “Macro-Macro” paradigm is investigated on the basis of a recent study on an entangled Micro-Macro system involving N≈105 particles. Crucial experimental issues as the violation of Bell’s inequalities by the Macro-Macro system are considered.

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.

Entangled states provide the necessary tools for conceptual tests of quantum mechanics and other alternative theories. These tests include local hidden variables theories, pre- and postselective quantum mechanics, QND measurements, complementarity, and tests of quantum mechanics itself against, e.g., the so-called causal communication constraint. We show how to produce various nonlocal entangled states of multiple cavity fields that are useful for these tests, using cavity QED techniques. First, we discuss the generation of the Bell basis states in two entangled cavities, (...) when there is at most one photon in either of the cavities, and then a straightforward generalization to similar N-cavity states. We then show how to produce a nonlocal entangled state when there is precisely one photon hiding in three cavities. These states can be produced by sending appropriately prepared atoms through the cavities. As applications we briefly review two proposals: one to test quantum mechanics against the causal communication constraint using a two-cavity entangled state and the other to test pre- and postselective quantum mechanics using a three-cavity entangled state. The outcome of the latter experiment can be discussed from the viewpoint of the consistent histories interpretation of quantum mechanics and therefore provides an opportunity to subject quantum cosmological ideas to laboratory tests. Finally, we point out the relation between these schemes and the schemes suggested for quantum computing, teleportation, and quantum copying. (shrink)

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.

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)

The article provides a reply to critical remarks made during the discussion about creativity and scientific knowledge. The authors propose to consider their concept of creativity not as antagonistic or incommensurable with the alternative, but rather co-existing through the complementarity principle. Responding to a comment about the socio-cultural conditionality of a particular cognitive situation, the authors question whether globalization seriously influence this matter in science. They support the statement about the importance of the interaction between science and art, science and (...) philosophy as an opportunity to consider scientific problems from the outside, in an unusual way. Regarding the comment about serendipity, the authors note that in certain cases we need exactly epistemological randomization, since we cannot consciously induce serendipity. In conclusion, thanks are expressed to all participants in the discussion. (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.

The article presents a social phenomenology of naturalism. Starting from Stefan Bargheer’s Moral entanglements (2018), it argues that to understand the transformations of naturalist practices, we have to focus both on the shifting typifications of activity and their organizational moorings, but also on the experiential affordances of practice. Drawing on the work of Schutz and Merleau-Ponty, I focus on the transformation of animals from background into figure, the peculiar province of meaning that naturalist practice entails, as well as the experience (...) of “play” that Bargheer highlights. Doing so, I argue that the affordances of experience are a constitutive aspect of any historical account of practice: that a phenomenological approach is crucial not only for the micro-sociology of interaction and experience, but for understanding larger historical processes and transformations.

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)

This paper deals with an (otherwise classical) two-(non-interacting) particle system immersed in a common stochastic zero-point radiation field. The treatment is an extension of the one-particle case for which it has been shown that the quantum properties of the particle emerge from its interaction with the background field under stationary and ergodic conditions. In the present case we show that non-classical correlations—describable only in terms of entanglement—arise between the (nearby) particles whenever both of them resonate to a common frequency of (...) the field. For identical particles the entanglement becomes maximum and must be described by totally (anti)symmetric states. (shrink)

In this study, we examine the influence of senior leadership on firms’ corporate social responsibility. We integrate upper echelons research that has investigated either the influence of the CEO or the top management team on CSR. We contend that functional experience complementarity between CEOs and TMTs in formulating and implementing CSR strategy may underlie differentiated strategies in CSR. We find that when CEOs who have predominant experience in output functions are complemented by TMTs with a lower proportion of members who (...) have experience in output functions, there is a pronounced effect on the community, product, and diversity dimensions of CSR. In turn, when output-oriented CEOs are complemented by output-oriented TMTs, we observe an effect on the employee relations dimension of CSR. Interestingly, we find no influence of CEO-TMT complementarity on the environment dimension of CSR. In general, our empirical results support the relevance of the interaction between CEOs and their TMTs in defining their firms’ CSR profile. (shrink)

In our performance Entangled Speech, we connect the integration of microbial agency into a new complex ‘common good’ with the shared values of language. Drawing on a posthuman commons we aim for a hybrid language that not only processes formal symbols but also interacts with the microbes in the speaker’s mouth. We argue that the metaphors historically used to frame the relationship between microbiomes and speech cannot account for the co-creative material relationship between human speech and posthuman microbial, environmental and (...) biotechnological needs. In our performances, first we harvest sensitized microbes from a speaker’s mouth who had repeated those phonemes, which lead to a deviation of pH of saliva. This makes the microbes sensitive for the further processing: via a spectrogram, phonemes repetitively spoken by the audience drive pumps, which add pheromones to the microbes, the pheromones, which then are faded out. In the microbes, for some replication cycles, an ecological adaptation to the individual phonemes persists, which – in our definition – affirms some phonemes as ecological and others to be deleted, thereby changing the alphabetical order of the input word. Although parts of the process are digitally animated, the major parts develop in real time. We propose ‘microbial speech’ as a category beyond semantic meaning, with ecological qualities such as a transcorporeal mattering between words and the body. We aim at a language becoming a biological state in order to protect its own ecology. We propose a more entangled mode of microbes existing in common with language, affirming posthumanist transversal relations of all living and non-living matter. (shrink)

This article is an account of the dynamics of interaction across the social sciences and neurosciences. Against an arid rhetoric of ‘interdisciplinarity’, it calls for a more expansive imaginary of what experiment – as practice and ethos – might offer in this space. Arguing that opportunities for collaboration between social scientists and neuroscientists need to be taken seriously, the article situates itself against existing conceptualizations of these dynamics, grouping them under three rubrics: ‘critique’, ‘ebullience’ and ‘interaction’. Despite their differences, each (...) insists on a distinction between sociocultural and neurobiological knowledge, or does not show how a more entangled field might be realized. The article links this absence to the ‘regime of the inter-’, an ethic of interdisciplinarity that guides interaction between disciplines on the understanding of their pre-existing separateness. The argument of the paper is thus twofold: (1) that, contra the ‘regime of the inter-’, it is no longer practicable to maintain a hygienic separation between sociocultural webs and neurobiological architecture; (2) that the cognitive neuroscientific experiment, as a space of epistemological and ontological excess, offers an opportunity to researchers, from all disciplines, to explore and register this realization.

Knowledge of the entanglement properties of the wave functions commonly used to describe quantum many-particle systems can enhance our understanding of their correlation structure and provide new insights into quantum phase transitions that are observed experimentally or predicted theoretically. To illustrate this theme, we first examine the bipartite entanglement contained in the wave functions generated by microscopic many-body theory for the transverse Ising model, a system of Pauli spins on a lattice that exhibits an order-disorder magnetic quantum phase transition under (...) variation of the coupling parameter. Results for the single-site entanglement and measures of two-site bipartite entanglement are obtained for optimal wave functions of Jastrow-Hartree type. Second, we address the nature of bipartite and tripartite entanglement of spins in the ground state of the noninteracting Fermi gas, through analysis of its two- and three-fermion reduced density matrices. The presence of genuine tripartite entanglement is established and characterized by implementation of suitable entanglement witnesses and stabilizer operators. We close with a broader discussion of the relationships between the entanglement properties of strongly interacting systems of identical quantum particles and the dynamical and statistical correlations entering their wave functions.

Such difficulties in the theory of elementary particles as the infinite magnitudes of energy and charge when one takes into account a particle's interactions with vacuum, call for a radical synthesis and generalization of quantum and relativistic ideas if a real solution is to be obtained. It is purposed here to demonstrate that, if a synthesis of this kind is aimed at, the analysis of the concept of being may be of some heuristic value.

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.

The integrity of the patient–physician relationship depends on maintaining professional boundaries. While ethicists and professional organisations have devoted significant consideration to the subject of sexual boundary transgressions, the subject of non-sexual boundaries, especially outside the mental health setting, has been largely neglected. While professional organisations may offer guidance on specific subjects, such as accepting gifts or treating relatives, as well as general guidance on transparency and conflict of interest, what is missing is a principle-based method that providers can use to (...) assess non-sexual interactions with patients that transcend norms of practice. This paper attempts to offer an operational model for such assessment that considers not only the traditional emphasis on beneficence, but also incorporates concerns over entanglement and concordance.

A case study of quantum mechanics is investigated in the framework of the philosophical opposition “mathematical model – reality”. All classical science obeys the postulate about the fundamental difference of model and reality, and thus distinguishing epistemology from ontology fundamentally. The theorems about the absence of hidden variables in quantum mechanics imply for it to be “complete” (versus Einstein’s opinion). That consistent completeness (unlike arithmetic to set theory in the foundations of mathematics in Gödel’s opinion) can be interpreted furthermore as (...) the coincidence of model and reality. The paper discusses the option and fact of that coincidence it its base: the fundamental postulate formulated by Niels Bohr about what quantum mechanics studies (unlike all classical science). Quantum mechanics involves and develops further both identification and disjunctive distinction of the global space of the apparatus and the local space of the investigated quantum entity as complementary to each other. This results into the analogical complementarity of model and reality in quantum mechanics. The apparatus turns out to be both absolutely “transparent” and identically coinciding simultaneously with the reflected quantum reality. Thus, the coincidence of model and reality is postulated as necessary condition for cognition in quantum mechanics by Bohr’s postulate and further, embodied in its formalism of the separable complex Hilbert space, in turn, implying the theorems of the absence of hidden variables (or the equivalent to them “conservation of energy conservation” in quantum mechanics). What the apparatus and measured entity exchange cannot be energy (for the different exponents of energy), but quantum information (as a certain, unambiguously determined wave function) therefore a generalized law of conservation, from which the conservation of energy conservation is a corollary. Particularly, the local and global space (rigorously justified in the Standard model) share the complementarity isomorphic to that of model and reality in the foundation of quantum mechanics. On that background, one can think of the troubles of “quantum gravity” as fundamental, direct corollaries from the postulates of quantum mechanics. Gravity can be defined only as a relation or by a pair of non-orthogonal separable complex Hilbert space attachable whether to two “parts” or to a whole and its parts. On the contrary, all the three fundamental interactions in the Standard model are “flat” and only “properties”: they need only a single separable complex Hilbert space to be defined. (shrink)

In the past three decades a number of narrative self-concepts have appeared in the philosophical literature. A central question posed in recent literature concerns the embodiment of the narrative self. Though one of the best-known narrative self-concepts is a non-embodied one, namely Dennett’s self as ‘a center of narrative gravity’, others argue that the narrative self should include a role for embodiment. Several arguments have been made in support of the latter claim, but these can be summarized in two main (...) points. Firstly, a logical one: without taking the body into account Dennett’s theory becomes self-refuting. Secondly, a more practical/phenomenological point: a disembodied self-concept overlooks how personal the body is, and as such should be considered part of the self. In this paper I endorse these criticisms of non-embodied narrative self-concepts, but I argue that the relationship between the narrative self and the body is far from sufficiently fleshed out. I claim that the narrative self and the body are much more interwoven than the above criticisms suggest. What I aim to show in this paper is that the relationship between the body and the narrative self is interactive rather than unidirectional: not only does our body shape our narrative self, but our narrative self also shapes our body. The upshot of this is a better conception of the self is as a dynamic interaction between its various aspects. (shrink)

Disorders of Consciousness (DoCs) raise difficult and complex questions about the value of life for persons with impaired consciousness, the rights of persons unable to make medical decisions, and our social, medical, and ethical obligations to patients whose personhood has frequently been challenged and neglected. Recent neuroscientific discoveries have led to enhanced understanding of the heterogeneity of these disorders, and focused renewed attention on the medical and ethical problem of misdiagnosis. -/- This book examines the entanglement of epistemic and ethical (...) uncertainty in DoCs and other medical contexts, and how they interact to create both epistemic and ethical risks. Philosopher and bioethicist L. Syd M Johnson pulls together multiple threads in this work: the ontological mysteries of consciousness, medical uncertainty about unconsciousness, ableist bias, withdrawal of treatment in neurointensive care, and the rarely questioned view that consciousness is essential to personhood and moral status. Johnson challenges longstanding bioethical dogmas about DoC patients, and argues for an ethics of uncertainty for contexts where there is a need for decisive action in the presence of unavoidable uncertainty. The ethics of uncertainty refocuses ethical inquiry concerning persons with DoCs, placing less emphasis on their contested personhood, and more on inductive risk and uncertainty, on respect for autonomy, and especially on epistemic justice. With applications to various decisional contexts where uncertainty and ethical risk interact, this ethical approach enables surrogate decision makers facing fraught and risky choices to fulfill their obligations as moral and epistemic agents.

Relating visual images to textual messages may have great potential in facilitating students’ reading comprehension. The inevitable and important presence of visuals in textbooks obliges language teachers to exploit all semiotic resources to deepen students’ understanding. However, analysis of how images interact with text in textbooks has been rare, and among the efforts it has generally been found that visuals and text often fail to achieve coherence. This study investigates whether and how text and image complement each other ideationally by (...) six sense relations and interpersonally by the Mood system in ninth-grade English as a Foreign Language textbooks to reach intersemiotic complementarity. The results revealed that ideational rather than interpersonal IC is more frequent, where many more Participants than Processes in the texts find their visual complements. Ideational IC is particularly high in Information Reports while Recounts generally mark higher percentages of interpersonal IC. To accomplish ideational IC, repetition is most frequent, followed by hyponymy and collocation. Distinct IC patterns also characterize the different editions of textbooks investigated, which may suggest their different potentials in catering to students of varying proficiencies. (shrink)

Although it is, often considered a form of anti-realism, here it is argued that Bohr's complementarity viewpoint must accept entity realism based on its analysis of the causal interaction involved in observation. However, because Bohr accepts the quantum postulate he must reject the view that the goal of theory is to represent the independently existing object apart from observation. Thus he abandons the spectator account of knowledge and with it the correspondence theory of truth. In this respect his view is (...) parallel to the positions held by Hacking, Cartwright, and Ellis.

Rudyard Kipling, the famous english author of « The Jungle Book », born in India, wrote one day these words: « Oh, East is East and West is West, and never the twain shall meet ». In my paper I show that Kipling was not completely right. I try to show the common ground between buddhist philosophy and quantum physics. There is a surprising parallelism between the philosophical concept of reality articulated by Nagarjuna and the physical concept of reality implied (...) by quantum physics. For neither is there a fundamental core to reality, rather reality consists of systems of interacting objects. Such concepts of reality cannot be reconciled with the substantial, subjective, holistic or instrumentalistic concepts of reality which underlie modern modes of thought. (shrink)

Biologists and philosophers often use the language of determination in order to describe the nature of developmental phenomena. Accounts in terms of determination have often been reductionist. One common idea is that DNA is supposed to play a special explanatory role in developmental explanations, namely, that DNA is a developmental determinant. In this article we try to make sense of determination claims in developmental biology. Adopting a manipulationist approach, we shall first argue that the notion of developmental determinant is causal. (...) We suggest that two different theses concerning developmental determination can be articulated: determination of occurrence and structural determination. We shall argue that, while the first thesis is problematic, the second, opportunely qualified, is feasible. Finally, we shall argue that an analysis of biological causation in terms of determination cannot account for entangled dynamics. Characterising causal entanglement as a particular kind of interactive causation whereby difference-making causes ascribable to different levels of biological organisation influence a particular ontogenetic outcome, we shall, via two illustrative examples, diagnose some potential limits of a reductionist, molecular and intra-level understanding of biological causation.

SummaryA short exposition is given of the foundation of the causal description in classical physics and the failure of the principle of causality in coping with atomic phenomena. It is emphasized that the individuality of the quantum processes excludes a separation between a behaviour of the atomic objects and their interaction with the measuring instruments denning the conditions under which the phenomena appear. This circumstance forces us to recognize a novel relationship, conveniently termed complementarity, between empirical evidence obtained under different (...) experimental conditions. An appropriate tool for a complementary mode of description is provided by the quantum‐mechanical formalism which allows us to account for regularities of definite or statistical character beyond the grasp of classical physical explanation. – N.

This study examines urban agriculture (UA) in Sacramento, California (USA), the nation's self-branded “Farm-to-Fork Capital,” in order to highlight UA’s distinct yet entangled roots. The study is based on 24 interviews with a diverse array of UA leaders, conducted as part of a five-year transdisciplinary study of UA in Sacramento. In it, we unearth three primary “taproots” of UA projects, each with its own historical legacies, normative visions, and racial dynamics. In particular, we examine UA projects with “justice taproots,” “health (...) taproots,” and “market taproots.” We use this analysis to understand how different kinds of UA projects are embedded in racial capitalism in ways that transform relationships between people, the city, and food systems. Unearthing these entangled roots helps illuminate UA’s underlying politics, showing how these roots grow in both competitive and symbiotic ways within the soil matrix of racial capitalism. We argue that these roots interact differently with racial capitalism, creating disparities in their growth trajectories. In particular, UA projects associated with the justice taproot are historically underrepresented and undervalued. However, we argue that there are some prospects for building alliances between the UA movement’s three roots, and that these are both promising and problematic. (shrink)

Although Niels Bohr's notion of complementarity is usually referred to in the context of quantum mechanics, it is not of physical origin. Bohr derived it from the philosophical idea of a holistic entanglement of knowledge and action. Bohr's complementarity primarily refers to a key element of the pragmatist tradition, the reflective relation between the immediate experience of an object and the awareness of its objectification. Similar relations have been observed by Kurt Goldstein in his studies of brain-injured patients. From a (...) pragmatic point of view, Goldstein's idea of adequacy in biological knowledge might lead to novel approaches to current ethical questions in medicine as well as biotechnology. (shrink)

Recently, several experimental tests devoted to quantitatively establish complementarity relations in quantum systems have been reported. Starting from the results of fully quantum single-particle self-nterference experiments, we critically review the concept of entanglement, arguing that this quantity is a peculiar trait of composite quantum systems, and thus it can be looked as a basic concept of quantum mechanics.

Impelled by the intertwined expansion of capitalist institutions and fossil-fueled industry, human activity has made devastating impacts on ecosystems and earth systems. The colonial, class, racial, and gender systems that coevolved with these historical processes have long been critiqued for engineering exploitation and inequality. Yet the technologies with which these systems interact are widely portrayed as neutral and nonpartisan. This paper interrogates the purported independence of technology on two fronts. First, it uses a political ecology lens to illuminate some ways (...) in which the generation and application of technology have been historically entangled with colonial, racial, and gender systems. Second, it considers how those entanglements have been variously obscured, acknowledged, depoliticized, and/or politicized in two realms of thought and practice: ecomodernism and degrowth. Conclusions call for bringing creative innovation of ecomodernism together with degrowth commitment to just social–ecological transformation. (shrink)

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.

Interactive social cognition theory and approaches of developmental psychology widely agree that central aspects of emotional and social experience arise in the unfolding of processes of embodied social interaction. Bi-directional dynamical couplings of bodily displays such as facial expressions, gestures, and vocalizations have repeatedly been described in terms of coordination, synchrony, mimesis, or attunement. In this paper, I propose conceptualizing such dynamics rather as processes of affective resonance. Starting from the immediate phenomenal experience of being immersed in interaction, I develop (...) the philosophical notion of affective resonance to refer to a dynamic entanglement of moving and being-moved in relation. The concept of affective resonance makes visible that the interaction dynamic itself creates an affective experience rather than transmitting internal feeling states between pre-existent individuals. This leads to a philosophical framework in which relationality and ontogeny are primary over separate individuals, and in which the naturalistic distinction of a fundamental physical level versus an emerging level of social processes has to be given up.

Despite the entangled universe cannot be considered merely as an enormously complex system, as it is reactive to actions and observations, references on quantum entanglement in living systems may help find ways in which quantum effects can move from the microscopic to the macroscopic, in realms where the mind/brain behave as a quantum object and is sensitive to the dynamic state of the entire universe. Taking up vision from a synaesthetic perspective as a perfusion of senses, and putting together a (...) myriad of references around this perception phenomenon, the idea is to work in the building of artistic experiences where vision takes up a tactile function, emerging from a tension between the movements governed by the interaction of the attractors.
