It is argued that a realistic interpretation of quantum mechanics is possible and useful. Current interpretations, from “Copenhagen” to “many worlds” are critically revisited. The difficulties for intuitive models of quantum physics are pointed out and possible solutions proposed. In particular the existence of discrete states, the quantum jumps, the alleged lack of objective properties, measurement theory, the probabilistic character of quantum physics, the wave–particle duality and the Bell inequalities are analyzed. The sketch of a (...) realistic picture of the quantum world is presented. It rests upon the assumption that quantum mechanics is a stochastic theory whose randomness derives from the existence of vacuum fields. They correspond to the vacuum fluctuations of quantum field theory, but taken as real rather than virtual. (shrink)

Entanglement was initially thought by some to be an oddity restricted to the realm of thought experiments. However, Bell’s inequality delimiting local - behavior and the experimental demonstration of its violation more than 25 years ago made it entirely clear that non-local properties of pure quantum states are more than an intellectual curiosity. Entanglement and non-locality are now understood to figure prominently in the microphysical world, a realm into which technology is rapidly hurtling. Information theory is also increasingly recognized (...) by physicists and philosophers as intimately related to the foundations of mechanics. The clearest indicator of this relationship is that between quantum information and entanglement. To some degree, a deep relationship between information and mechanics in the quantum context was already there to be seen upon the introduction by Max Born and Wolfgang Pauli of the idea that the essence of pure quantum states lies in their provision of probabilities regarding the behavior of quantum systems, via what has come to be known as the Born rule. The significance of the relationship between mechanics and information became even clearer with Leo Szilard’s analysis of James Clerk Maxwell’s infamous demon thought experiment. Here, in addition to examining both entanglement and quantum information and their relationship, I endeavor to critically assess the influence of the study of these subjects on the interpretation of quantum theory.

We discuss a recent work by J. Lawrence et al. [arxiv.org/abs/2208.11793] criticizing relational quantum mechanics (RQM) and based on a famous nonlocality theorem Going back to Greenberger Horne and Zeilinger (GHZ). Here, we show that the claims presented in this recent work are unjustified and we debunk the analysis.

This thesis is an attempt to reconstruct the conceptual foundations of quantum mechanics. First, we argue that the wave function in quantum mechanics is a description of random discontinuous motion of particles, and the modulus square of the wave function gives the probability density of the particles being in certain locations in space. Next, we show that the linear non-relativistic evolution of the wave function of an isolated system obeys the free Schrödinger equation due to the requirements of (...) spacetime translation invariance and relativistic invariance. Thirdly, we argue that the random discontinuous motion of particles may lead to a stochastic, nonlinear collapse evolution of the wave function. A discrete model of energy-conserved wavefunction collapse is proposed and shown to be consistent with existing experiments and our macroscopic experience. In addition, we also give a critical analysis of the de Broglie-Bohm theory, the many-worlds interpretation and other dynamical collapse theories, and briefly discuss the issue of unifying quantum mechanics and special relativity.

The predominant function of Australian clinical ethics committees (CECs) is policy formation. Some committees have an educational role. Few committees play any direct role in advising on ethics in the management of individual patients and this occurs only in exceptional circumstances. There is a tendency to exaggerate both the number and function of committees. It is suggested that studies of ethics committees, based on questionnaire surveys, should be interpreted cautiously. An examination of ethical issues indicates that there is a role (...) for a critical analysis of power relations in Australian hospitals that is not fulfilled by CECs. (shrink)

Free Energy Principle underlies a unifying framework that integrates theories of origins of life, cognition, and action. Recently, FEP has been developed into a Markovian monist perspective. The paper expresses scepticism about the validity of arguments for Markovian monism. The critique is based on the assumption that Markovian models are scientific models, and while we may defend ontological theories about the nature of scientific models, we could not read off metaphysical theses about the nature of target systems from our theories (...) of nature of scientific models. The paper draws attention to different ways of understanding Markovian models, as material entities, fictional entities, and mathematical structures. I argue that none of these interpretations contributes to the defence of a metaphysical stance. This is because scientific representation is a sophisticated process, and properties of Markovian models—such as the property of being neither physical nor mental—could not be projected onto their targets to determine the ontological properties of targets easily.

The Orthodox Churches are part of the ecumenical movement with the inner wish to clarify the theological elements which keep the whole Christianity divided. For this goal, every Church is represented somehow in discussions by her theologians who are training to carry a theological dispute at this level. The Romanian Orthodox Church was indirectly represented in the World Council of Church by professor Ion Bria (1929-2002), who had worked officially at the Ecumenical Centre in Geneva for more than 20 years. (...) This theological research has the aim to speak to us about Bria’s personality and ecumenical activity. In order to accomplish this goal, I will expand my research in three chapters. In the first one, I will present his biographical life. Until this moment he remains the most important Romanian theologian involved in the ecumenical dialogue. The second chapter deals with the history of the modern ecumenical movement and also with Bria’s perspective on the dialogue between Orthodoxy and ecumenism, which are for him two correlative elements. Bria comes to confront the anti-ecumenical part within the Orthodox Church who does not accept the Christian dialogue being afraid of heresy. Bria explain how through dialogue, the line between Orthodoxy and the other Christians can be overrun. In the third chapter I explain the missionary concept ‘liturgy after the Liturgy’, both historically and theologically. Being aware that there are some uncertainties around this concept I decided to clarify it in a proper way. Bria is known as the promoter of this concept, so I will search to find out who is the originator of this expression as such. In the same chapter I will analyze the ecclesiological elements from Bria’s writings. The ecumenical dialogue is interpreted of being an ecclesiological problem par excellence so I will outline Bria’s position regarding the teaching of the Church. In conclusion I will present in a synthetic way the results of this study. (shrink)

The analysis, with the use of two state vectors, of a quantum system, during the time interval between two measurements, leads to some amazing results, which seem to contradict our usual “quantum common sense.” We explore the questions of compatibility with the conventional quantum theory, uniqueness of pre- and post-selected ensembles, commutativity, simultaneity and reality of strong and weak values in the intermediate time, and the meaning of the weak value. Common criticisms are shown to be (...) unfounded. (shrink)

This brief survey analyzes the epistemological implications about the role of observer in the interpretations of Quantum Mechanics. As we know, the goal of most interpretations of quantum mechanics is to avoid the apparent intrusion of the observer into the measurement process. In the same time, there are implicit and hidden assumptions about his role. In fact, most interpretations taking as ontic level one of these fundamental concepts as information, physical law and matter bring us (...) to new problematical questions. We think, that no interpretation of the quantum theory can avoid this intrusion until we do not clarify the nature of observer. (shrink)

The aim of the article is to define and investigate an interpretative framework for the philosophy of Leopold Blaustein, a student of Twardowski in Lwów and Husserl in Freiburg im Breisgau. The author defends the thesis that it is justified to refer to Blaustein’s philosophy not as phenomenology sensu stricto, but as a phenomenologically-oriented descriptive psychology related but not equivalent to the project expounded by Husserl in the first edition of Logische Untersuchungen as well as in his project of phenomenological (...) psychology. The article traces Blaustein’s critique of Husserl’s phenomenological methods, putting it in the historical context of the discussion with Ingarden. Next, the author juxtaposes Blaustein’s understanding of psychology with Husserl’s project of 1925, which makes it possible to identify not only the differences between the two projects, but also their similarities. The article also raises questions about the scope of descriptive-psychological analyses. (shrink)

Under the present judicial interpretation of federal securities law, an individual is prohibited from trading on non-public information that has been misappropriated in contravention of a fiduciary duty. Trades made using non-pubIic information that has not been misappropriated are not prohibited by Rule 10b-5, promulgated under the Securities and Exchange Act of 1934. The current requirement of misappropriation to trigger Rule 10b-5 liability creates a gap that permits transactions that are both ethically and economically undesirable. Judicial or legislative reforms are (...) recommended to close the gap and help ensure the fairness and efficiency of securities markets. (shrink)

In African society today, ubuntu as a notion of African humanism has been, and still is, subject to critical discussion. In African literature, philosophy, ethics, anthropology and theology, ubuntu plays a vast role and scholars in Africa and globally find the notion highly debated. The concept of identity development on the African continent has been written about broadly. This article unpacks the ubuntu philosophies of Augustine Shutte, Kwame Gyekye and John Mbiti. The views of these scholars will be contrasted (...) to critically engage the conceivable commonalities for identity development through cultures. The question addressed herein is: What are the similarities and dissimilarities of ubuntu as a cornerstone for identity development in modern Africa? This article also examines the divergent definition and historical development of ubuntu culture, ubuntu philosophy of identity development, environmental development and various thinkers’ understanding of this African worldview in current Africa and further afield. Contribution: This research contributes to African theological ethics of the new landscape identity and explores the ubuntu worldviews as a developmental process of identities across cultures. Since identity development across cultures is highly dynamic, the hermeneutical interpretation of the principles of ubuntu is crucial. (shrink)

The concept of the "new working class" was advanced by French Left radical sociologists 15 years ago, at a time when the social consequences of the revolution in science and technology under the conditions of governmentally intertwined monopoly capitalism had not yet become sufficiently clear. Bourgeois ideology hastened to interpret the social changes within the world of hired labor as the "dissolving" of the working class, its loss of revolutionary consciousness, and its integration into industrial society. Against this background, the (...) concept of the "new working class" stood out primarily because of its bearings on revolution: it asserted that the carrier of revolutionary ideas in the world today is precisely the working class, but not this class as a whole, only the portion of it associated with advanced branches of the economy. The concept of the "new working class" differed from the programs of the "New Left," with their spontaneous, emotional protest, in that it possessed a comprehensive, theoretical argumentum, reflecting both the changes in the economic and technological conditions of contemporary capitalism and the evolution of the social psychology of class consciousness.

abstract Mou Zongsan used to say that in Western philosophy there exist three different traditions. The first is the tradition of Plato and Aristoteles, the second is the tradition of Kant and Hegel, and the last is the tradition of Leibniz and Russell. I am afraid, however, that this kind of interpretation is already outdated and incapable of encompassing the rich variegations of Western philosophy as a whole. In my view, the various options would have been exhausted by supplementing the (...) preceding list with the tradition founded by Husserl and Heidegger and the one set up by Whitehead. All of these traditions together encapsulate the most important domains of philosophy, such as ontology, epistemology, and axiology. In this article I closely investigate the epistemological thought of Bertrand Russell in order to find out whether it contains any aspects from which we can borrow and learn. (shrink)

Biological systems exhibit complexity at all levels of organization. It has recently been argued by Michael Behe that at the biochemical level a type of complexity exists--irreducible complexity--that cannot possibly have arisen as the result of natural, evolutionary processes and must instead be the product of (supernatural) intelligent design. Recent work on self-organizing chemical reactions calls into question Behe's analysis of the origins of biochemical complexity. His central interpretative metaphor for biochemical complexity, that of the well-designed mousetrap that ceases (...) to function if critical parts are absent, is undermined by the observation that typical biochemical systems exhibit considerable redundancy and overlap of function. Real biochemical systems, we argue, manifest redundant complexity--a characteristic result of evolutionary processes. (shrink)

This book studies the foundations of quantum theory through its relationship to classical physics. This idea goes back to the Copenhagen Interpretation (in the original version due to Bohr and Heisenberg), which the author relates to the mathematical formalism of operator algebras originally created by von Neumann. The book therefore includes comprehensive appendices on functional analysis and C*-algebras, as well as a briefer one on logic, category theory, and topos theory. Matters of foundational as well as mathematical interest (...) that are covered in detail include symmetry (and its "spontaneous" breaking), the measurement problem, the Kochen-Specker, Free Will, and Bell Theorems, the Kadison-Singer conjecture, quantization, indistinguishable particles, the quantum theory of large systems, and quantum logic, the latter in connection with the topos approach to quantum theory.

The stochastic scheme proposed in a previous paper as subjacent to quantum mechanics is analyzed in the light of the difficulties and criticisms encountered by similar attempts. It is shown that the limitation of the domain where the theory is valid gives a reply to the criticisms, but restricts its practical usefulness to the description of basic features. A stochastic approach of the hadron mass spectrum, allowing the scheme to emerge in the domain of experimental verification (to be worked (...) out in a later paper) is outlined. The model is found not to be in disagreement with Bell's argument opposed to hidden variables; a same origin is suggested for the difficulties encountered in both domains. The views proposed are compared with the Copenhagen interpretation: common points and divergences are analyzed. (shrink)

This book investigates whether treaty interpretation at the ECtHR and WTO, which are sometimes perceived as promoting 'self-contained' regimes, could constitute a means for unifying international law, or, conversely, might exacerbate the fragmentation of international law. In this regard, the practice of the ICJ on treaty interpretation is used for comparison, since the ICJ has made the greatest contribution to the development and clarification of international law rules and principles. Providing a critical analysis of cases at the ICJ, (...) ECtHR and WTO, both prior to and since the adoption of the 1969 Vienna Convention on the Law of Treaties, the book reveals how the ECtHR and WTO apply the general rules of treaty interpretation in patterns which are similar to those used by the ICJ to address difficulties in interpreting the text of treaties. Viewed in the light of the ECtHR's and WTO's interpretative practices, both the VCLT's general rules of interpretation and the ICJ's interpretative practice serve to counteract the fragmentation of international law..

The validity of the conclusion to the nonlocality of quantum mechanics, accepted widely today as the only reasonable solution to the EPR and Bell issues, is questioned and criticized. Arguments are presented which remove the compelling character of this conclusion and make clear that it is not the most obvious solution. Alternative solutions are developed which are free of the contradictions related with the nonlocality conclusion. Firstly, the dependence on the adopted interpretation is shown, with the conclusion that the (...) alleged nonlocality property of the quantum formalism may have been reached on the basis of an interpretation that is unnecessarily restrictive. Secondly, by extending the conventional quantum formalism along the lines of Ludwig and Davies it is shown that the Bell problem may be related to complementarity rather than to nonlocality. Finally, the dependence on counterfactual reasoning is critically examined. It appears that locality on the quantum level may still be retained provided one accepts a newly proposed principle of nonreproducibility at the individual quantum level as an alternative of quantum nonlocality. It is concluded that the locality principle can retain its general validity, in full conformity with all experimental data. (shrink)

The overall purpose of this paper is to clarify the physical meaning and epistemological status of the term 'measurement' as used in quantum theory. After a review of the essential logical structure of quantum physics, Part I presents interpretive discussions contrasting the quantal concepts observable and ensemble with their classical ancestors along the lines of Margenau's latency theory. Against this background various popular ideas concerning the nature of quantum measurement are critically surveyed. The analysis reveals that, (...) in addition to internal mathematical difficulties, all the so-called quantum theories of measurement are grounded in unjustifiable, classical presuppositions.

How can we be certain of what a physics theory is talking about and, at the same time, not have a clue what the theory is about? Yet, this seemingly nonsensical question lurks in the background since the advent of quantum physics and is intimately entangled with the cluster of issues constituting the raw material for philosophers of science striving to negotiate the so-called classical to quantum divide.The discourse of theoretical physics unfolds on two levels: the experimental and (...) the mathematical. It is based on the competent use of everyday language, significantly enriched with sharply defined concepts, in order to deploy necessary resources, to set up and faithfully describe an experimental procedure, and to unambiguously communicate its results. And it expresses in mathematical form properties, states, their interrelations and transformations in the context of an overall conceptual framework.The synthesis of the two levels of discourse, established through the co-evolution of phy ..

In this paper we critically review the various attempts that have been made to understand quantum field theory. We focus on Teller's (1990) harmonic oscillator interpretation, and Bohm et al.'s (1987) causal interpretation. The former unabashedly aims to be a purely heuristic account, but we show that it is only interestingly applicable to the free bosonic field. Along the way we suggest alternative models. Bohm's interpretation provides an ontology for the theory--a classical field, with a quantum equation of (...) motion. This too has problems; it is not Lorentz invariant. (shrink)

The hidden-variable theorems of Bell and followers depend upon an assumption, namely the hidden-variable assumption, that conflicts with the precepts of quantum philosophy. Hence from an orthodox quantum perspective those theorems entail no faster-than-light transfer of information. They merely reinforce the ban on hidden variables. The need for some sort of faster-than-light information transfer can be shown by using counterfactuals instead of hidden variables. Shimony’s criticism of that argument fails to take into account the distinction between no-faster-than-light connection (...) in one direction and that same condition in both directions. The argument can be cleanly formulated within the framework of a fixed past, open future interpretation of quantum theory, which neatly accommodates the critical assumptions that the experimenters are free to choose which experiments they will perform. The assumptions are compatible with the Tomonaga–Schwinger formulation of quantum field theory, and hence with orthodox quantum precepts, and with the relativistic requirement that no prediction pertaining to an outcome in one region can depend upon a free choice made in a region spacelike-separated from the first.

To solve the probability problem of the Many Worlds Interpretation of Quantum Mechanics, D. Wallace has presented a formal proof of the Born rule via decision theory, as proposed by D. Deutsch. The idea is to get subjective probabilities from rational decisions related to quantum measurements, showing the non-probabilistic parts of the quantum formalism, plus some rational constraints, ensure the squared modulus of quantum amplitudes play the role of such probabilities. We provide a new presentation of (...) Wallace’s proof, reorganized to simplify some arguments, and analyze it from a formal perspective. Similarities with classical decision theory are made explicit, to clarify its structure and main ideas. A simpler notation is used, and details are filled in, making it easier to follow and verify.

The underlying physical reality is a central notion in the interpretations of quantum mechanics. The a priori physical reality notion affects the corresponding interpretation. This paper explore the possibility to establish a relationship between philosophical concept of physical reality in Nagarjuna's epistemology (emptiness) and the picture of underlying physical reality in Einstein, Rovelli and Zeilinger positions. This analysis brings us to conclude that the notion of property of a quantum object is untenable. We can only speak (...) about relational property of the object. On this basis, we are stimulated to build a new ontology of underlying physical reality: a relational ontology. Finally, we argue that Nagarjuna's view is comparable with Rovelli's interpretation of quantum mechanics. These views eliminate the privileged role of the observer. (shrink)

Buddhist Illogic. The 2nd Century CE Indian philosopher Nagarjuna founded the Madhyamika (Middle Way) school of Mahayana Buddhism, which strongly influenced Chinese, Korean and Japanese (Ch’an or Zen) Buddhism, as well as Tibetan Buddhism. Nagarjuna is regarded by many Buddhist writers to this day as a very important philosopher, who they claim definitively proved the futility of ordinary human cognitive means. His writings include a series of arguments purporting to show the illogic of logic, the absurdity of reason. He considers (...) this the way to verbalize and justify the Buddhist doctrine of “emptiness” (Shunyata). These arguments attack some of the basic tenets and techniques of reasoning, such as the laws of thought (identity, non-contradiction and the excluded middle), conceptualization and predication, our common assumptions of self, entities and essences, as well as our beliefs in motion and causation. The present essay demonstrates the many sophistries involved in Nagarjuna’s arguments. He uses double standards, applying or ignoring the laws of thought and other norms as convenient to his goals; he manipulates his readers, by giving seemingly logical form (like the dilemma) to his discourse, while in fact engaged in non-sequiturs or appealing to doubtful premises; he plays with words, relying on unclear terminology, misleading equivocations and unfair fixations of meaning; and he ‘steals concepts’, using them to deny the very percepts on which they are based. Although a critique of the Madhyamika philosophical interpretation and defense of “emptiness”, Buddhist Illogic is not intended to dissuade readers from Buddhism. On the contrary, its aim to enhance personal awareness of actual cognitive processes, and so improve meditation. It is also an excellent primer on phenomenological epistemology. (shrink)

Having analyzed the formal aspects of Wallace’s proof of the Born rule, we now discuss the concepts and axioms upon which it is built. Justification for most axioms is shown to be problematic, and at times contradictory. Some of the problems are caused by ambiguities in the concepts used. We conclude the axioms are not reasonable enough to be taken as mandates of rationality in Everettian Quantum Mechanics. This invalidates the interpretation of Wallace’s result as meaning it would be (...) rational for Everettian agents to decide using the Born rule. (shrink)

According to the modal interpretation, the standard mathematical framework of quantum mechanics specifies the physical magnitudes of a system, which have definite values. Probabilities are assigned to the possible values that these magnitudes may adopt. The interpretation is thus concerned with physical properties rather than with measurement results: it is a realistic interpretation. One of the notable achievements of this interpretation is that it dissolves the notorious measurement problem. The papers collected here, together with the introduction and concluding (...) class='Hi'>critical appraisal, explain the various forms of the modal interpretation, survey its achievements, and discuss those problems that have yet to be solved.

Recent developments regarding the pharmacology of psychoactive substances are significant for treating depressions or opioid addictions. Current theories, hypotheses, and models of drug effects assume a cause–effect narrative, which is based on a stimulus/response mechanism. These narratives prioritize effects rather than conscious experiences. In this sense, drug experiences are quickly subsumed into common categories and codes of biological determinism. If subjective experiences are in the focus of the research, it quickly becomes a link to mystical, spiritual, or transcendental narratives. These (...) classifications lead to epistemological doublets (Gadamer). In this article, psychedelic experiences of drug users are analyzed in the frame of the pharmaco-analysis by Deleuze/Guattari. These framed psychedelic experiences are interpreted by means of a non-philosophical approach through philo-fictions (Laruelle), i.e., contradictory assumptions and hyperspeculations. In this respect, the aim of this article is to bring philo-fictions in relation to psychedelic experiences and to discuss them with models of information science, quantum mechanics, new materialism, and the philosophy of immanence. The result will be an open synthesis, with the assumption of further reflections on the agency, immanence, and the wholeness of matter. (shrink)

This paper is a critical suvery on the philosophy and the Interpretations of Quantum Mechanics.

By questioning the validity of some of our basic concepts, such as space, object, and causality, quantum physics contributes quite decisively to the dramatic changes now taking place in our world picture. Veiled Reality provides a detailed view of the reasons why such a questioning arises, a survey of the corresponding conceptual and theoretical problems, and a comprehensive, up-to-date account, useful to scientists and epistemologists alike, of the various ways present-day physicists tackle these problems.The book deals with the E.P.R. (...) reality criterion, local causality, and quantum measurement including relativistic quantum collapse, decoherence theories, consistent histories approaches, and ontologically interpretable theories. Questions bearing on the connection between counterfactuality and realism, intersubjective agreement, and limits of the bearing of the verbs “to have” and “to be,” follow naturally from the analysis and are thoroughly examined. Finally, distinguishing between empirical reality and a veiled independent reality whose only knowable features are structural yields a clue to a plausible interpretation of current physics.Accessible to readers with only very elementary background in modern physics, Veiled Reality offers nonspecialists, including students in physics and philosophy, easy access to basic problems in the foundation of physics.

A number of authors have commented on the topic of mandated reporting in cases of suspected child maltreatment and the application of this requirement to researchers. Most of these commentaries focus on the interpretation of current legal standards and offer opinions for or against the imposition of mandated reporting laws on research activities.

This article critically examines the (...) ethical arguments made by authors on both sides of the debate. The conclusion is reached that researchers should be mandated reporters of child maltreatment because the current arguments do not justify their exclusion from current ethical and legal standards.

In this work we attempt to confront the orthodox widespread claim, present in the philosophical and foundational debates about Quantum Mechanics (QM), that ‘superpositions are never actually observed in the lab’. In order to do so, we begin by providing a critical analysis of the famous measurement problem which, we will argue, was originated as a consequence of the strict application of the empirical-positivist requirements to subsume the quantum formalism under their specific understanding of a physical (...) ‘theory’. In particular, the ad hoc introduction of the projection postulate (or measurement rule) can be understood as the necessity of imposing a naive empiricist standpoint which presupposes that observations are self evident givens of “common sense” experience independent of metaphysical (or conceptual) presuppositions yet necessarily represented in binary terms. We then turn our attention to two “non-collapse” interpretations of QM—namely, modal and many worlds—which even though deny that the “collapse” is a real physical process retain anyhow the projection rule as a necessary axiom of the theory itself. In contraposition, following Einstein’s claim that “it is only the theory which decides what can be observed”, we propose a return to the realist representational understanding of physical theories in which ‘observation’ is not a “self evident” given of experience but something that can be only understood in the context of a theoretical (formal-conceptual) scheme. It is from this standpoint that we discuss a new non-classical conceptual representation which allows us to understand quantum phenomena in an intuitive (anschaulicht) manner. Leaving behind the projection postulate, we discuss the general physical conditions for measuring and observing quantum superpositions in the lab. (shrink)

E. Schrödinger's ideas on interpreting quantum mechanics have been recently re-examined by historians and revived by philosophers of quantum mechanics. Such recent re-evaluations have focused on Schrödinger's retention of space–time continuity and his relinquishment of the corpuscularian understanding of microphysical systems. Several of these historical re-examinations claim that Schrödinger refrained from pursuing his 1926 wave-mechanical interpretation of quantum mechanics under pressure from the Copenhagen and Göttingen physicists, who misinterpreted his ideas in their dogmatic pursuit of the complementarity (...) doctrine and the principle of uncertainty. My analysis points to very different reasons for Schrödinger's decision and, accordingly, to a rather different understanding of the dialogue between Schrödinger and N. Bohr, who refuted Schrödinger's arguments. Bohr's critique of Schrödinger's arguments predominantly focused on the results of experiments on the scattering of electrons performed by Bothe and Geiger, and by Compton and Simon. Although he shared Schrödinger's rejection of full-blown classical entities, Bohr argued that these results demonstrated the corpuscular nature of atomic interactions. I argue that it was Schrödinger's agreement with Bohr's critique, not the dogmatic pressure, which led him to give up pursuing his interpretation for 7 yr. Bohr's critique reflected his deep understanding of Schrödinger's ideas and motivated, at least in part, his own pursuit of his complementarity principle. However, in 1935 Schrödinger revived and reformulated the wave-mechanical interpretation. The revival reflected N. F. Mott's novel wave-mechanical treatment of particle-like properties. R. Shankland's experiment, which demonstrated an apparent conflict with the results of Bothe–Geiger and Compton–Simon, may have been additional motivation for the revival. Subsequent measurements have proven the original experimental results accurate, and I argue that Schrödinger may have perceived even the reformulated wave-mechanical approach as too tenuous in light of Bohr's critique.

This unpublished 1990 preprint argues that a crucial distinction in discussions of the many-worlds interpretation of quantum mechanics (MWI) is that between versions of the interpretation positing a physical multiplicity of worlds, and those in which the multiplicity is merely psychological, and due to the splitting of consciousness upon interaction with amplified quantum superpositions. It is argued that Everett's original version of the MWI belongs to the latter class, and that most of the criticisms leveled against the MWI, (...) in particular that it is illogical or incoherent, are not valid against such "psychological-multiplicity" versions. Attempts to derive the quantum-mechanical probabilities from the many-worlds interpretation are reviewed, and Everett's initial derivation is extended in an attempt to show that these are the unique possible probabilities. But there remains a challenge for proponents of the MWI: to show that their interpretation requires probabilities, rather than merely nonprobabilistic indeterminacy. A 2002 preface, revised in 2004, briefly discusses the extent to which I still agree with the claims in the paper. While its derivation of probabilities used, and failed to justify, noncontextuality, I still agree with the paper's general interpretation of the MWI, though not with the MWI itself. (shrink)

The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', was independently developed by Murray Gell-Mann and James Hartle and extended to quantum cosmology. Criticisms of CH involve issues of meaning, truth, objectivity, and coherence, a mixture of philosophy and physics. We will briefly consider the original formulation of CH and some basic objections. The reply to these objections, like the objections themselves, (...) involves a mixture of physics and philosophy. These replies support an evaluation of the CH formulation as a replacement for the measurement, or orthodox, interpretation. (shrink)

It was widely believed among post-classical thinkers that the classical Mutakallimūn held that the cause of dependence of an effect on a cause was its origination, or a combination of origination and contingency, or its contingency on condition of its origination. Some post-classical thinkers, led by al-Sayyid al-Sharif al-Jurjānī, went further by interpreting Abu’l-Hasan al-Ashʿarī’s denial of the persistence of accidents was a consequence of his view that origination was the cause of dependence. This is because the origination view entailed (...) that the world was no longer in need of the Creator after its origination, and thus, him and his followers sought to deflect this consequence by holding that accidents do not persist, and since the persistence of substances was dependent on those accidents, and accidents do not persist more than one moment, those substances remained in need of the Creator for those accidents after their origination. This article seeks to investigate this analysis of the Shaykh al-Ashʿarī’s view, alongside the leading scholars of his school. After examining the original sources of classical Ashʿarī thinkers, along with the Baṣran Mu’tazila, and the texts of Ibn Sina, it becomes clear that the Ashꜥarīs did not hold that accidents did not persist in order to deflect that purported consequence. Indeed, it becomes clear that they did not hold that origination was the cause of dependence, but rather, that it was contingency. As for the Mu’tazila, they are explicit that the cause of dependence is origination, and that is based on their view on the reality of the nonexistent. Since essences are real in their state of nonexistence, they are not in need of a cause; and everything that obtains for those essences after they come into exist are entailments of that essence; thus, they only stand in need of a cause in their origination, that is, going from nonexistence into existence. Indeed, they are also explicit that effects do not need the Creator after their origination, and they clarified this through a comparison with a builder and a building. Indeed, the classical Ashꜥarīs criticized them for this, just as Ibn Sina did in the Ishārāt wa’l-tanbīhāt, al-Najāt, and al-Shifā. Thus, those post-classical scholars generalized the statement that origination is the cause of dependence to all classical mutakallimūn, and then they interpreted Ashʿarī’s motivation behind the denial of the persistence of accidents in accordance with that. The truth, however, is that his view on accidents is based on contingency, and that is because a substance is possible of persistence and possible of non-persistence, and therefore, it stands in need of cause to determine its state in the subsequent moment. That determination must entail something additional to the substance itself, otherwise, the effect is redundant. That additional property must be an accident, and since it is impossible for an accident to subsist in an accident, it is not possible for an accident to persist, because it is not receptive to the property which entails persistence; meanwhile, it is possible for substances, because they can sustain accidents.

The article takes under consideration three versions of the ensemble interpretation of quantum mechanics and discusses the interconnection of these interpretations with the philosophy of science. To emphasize the specifics of the problem of interpretation of quantum mechanics in the USSR, the Marxist ideology is taken into account. The present paper continues the author’s previous analysis of ensemble interpretations which emerged in the USA and USSR in the first half of the 20th century. The author (...) emphasizes that the ensemble approach turned out to be a dead end for the development of the interpretation of quantum mechanics in Russia. The article also argues that in Soviet Russia, the classical Copenhagen approach to quantum mechanics was used. The Copenhagen approach was developed by Lev Landau in 1919–1931 and became the basis of the Landau-Lifshitz famous course on quantum mechanics, one of the classics of twentieth-century physics literature. Although Vladimir A. Fock’s approach to the interpretation of quantum mechanics differs from the standard presentation by Lev Landau and Evgeny Lifshitz, Fock put forward a very important principle that complementarity is a “firmly established law of nature”. The fundamental writings of Lev Landau, Vladimir Fock and Igor Tamm, the authors of the mid-twentieth century, did a lot to defend the standard point of view such as the popular interpretations by Landau and Lifshitz. This approach can be traced back to Landau’s early writings and to Fock’s criticism of the ensemble approach. (shrink)

To the mind of humans death is an impossible riddle, the ultimate of mysteries; therefore it has always been considered a task of paramount importance for philosophers to provide a satisfactory account for death. Among the numerous efforts to deal with the riddle of death, Epicurus’ one stands out not only for its unsurpassed simplicity and lucidness, but also for the innovative manner in which it approaches the issue: Epicurus denounces the fear of death as a profoundly unfruitful, unreasonable and (...) unjustifiable passion of the mind. In this short paper I will first provide a brief account of Epicurus’ argumentation. Then I will argue that, although Epicure’s efforts to annihilate the fear of death proved to be unconvincing (people never ceased to fear death), still in a way they have been successful. Epicurus managed to rationalize in a certain degree the most deeply rooted fear in the souls of humans, and this seems to have been his initial purpose: consolation sometimes is due not only to definite resolution, but also to doubt and inconclusiveness.

The central theme in the discussion of how education about religion can, and should, be developed in pluralistic societies concerns challenges and opportunities involving intercultural religious education (RE). One example is Robert Jackson’s report Signposts, commissioned by the Council of Europe, in which various aspects of intercultural competence are captured and made visible regarding a religious didactic context. Here, different dimensions of what can be described as ‘ethical competence’ appear to be central. In this article, the interpretive approach, strongly connected (...) with Jackson, is considered to be in need of a development of a theoretical framing of forceful strategies for handling ethical challenges taking place in multicultural, multireligious and multi-confessional classrooms. It is argued that such strategies will depend on a careful analysis of the concept of ethical competence. A theoretical platform for the argument is presented with reference to James Rest’s analysis of ethical competence, which is shown to be relevant to an examination of how the concept of ethical competence can contribute to the development of strategies for teaching intercultural RE. As a basis for this examination, the Danish, Finnish and Norwegian syllabuses for compulsory school RE are analysed regarding how they express conceptions of ethical competence. This selection shaped the curricular arena of the investigation as being non-confessional, whilst simultaneously, more or less explicitly, resting on a shared historical Protestant anchorage. This twofold interpretation is shown to allow for an analysis of ethical competence, in relation to which an identification of certain prerequisites for developing strategies for teaching intercultural RE is possible.

ABSTRACTThe aim of this narrow-focused text is to argue against the claim that the appresentation of unperceived features of objects that is implied in perceptual intentionality presupposes a reference to perceptions other subjects could have of these objects. This claim, as it has been defended by Dan Zahavi, rests upon an erroneous supposition about the modal status of the perceptual possibilities to which the perceived object refers, which shall not be interpreted as effectively realizable but as mere de jure possibilities, (...) perceptions that could have been realized in principle, but that are maybe beyond one’s reach considering one’s concrete factual powers and opportunities. Horizontal intentionality is better accounted for in terms of perceptions that one could have had because of one’s embodied character and the always open possibility of occupying another position with respect to the object. This modal ubiquity which is inherent to one’s being-in-space is what supports the field of de jure possibil... (shrink)

Review of "The Collected Works of Eugene Paul Wigner", Volume I, III, and VI. Excerpt from the Conclusions: Many of Wigner’s papers on mathematical physics are great classics. Most famous is his work on group representations which is of lasting value for a proper mathematical foundation of quantum theory. The modern development of quantum theory (which is not reflected in Wigner’s work) is in an essential way a representation theory (e.g. representations of kinematical groups, or representations of C*-algebras). (...) This view owes very much to Wigner’s seminal papers on the unitary representations of compact and noncompact groups. Wigner showed much courage in relating the then unresolved questions of the measurement problem to the much deeper problem of consciousness. In view of this very unorthodox proposal it is astonishing that Wigner was very reactionary with respect of the dogmas of orthodox quantum mechanics. In contrast to von Neumann himself, he took the old von-Neumann codification of quantum mechanics as authoritative and not to be questioned. Much of the efforts to interpret the meaning of this codification and to prove no-go theorems, such as the insolubility of the measurement problem or the impossibility of a quantum theory of individual objects, are physically irrelevant since they are based on a codification of quantum mechanics that is valid only for strictly closed systems with finitely many degrees of freedom. However, in nature there are no such systems. Every material system is coupled to the gravitational and to the electromagnetic field – systems which require in a Hamiltonian description infinitely many degrees of freedom. A deeper insight into the conceptual problems of quantum theory is possible only if the modern development of a quantum theory of infinite systems is taken into account. (shrink)
