Constructivist epistemology posits that all truths are knowable. One might ask to what extent constructivism is compatible with naturalized epistemology and knowledge obtained from inference-making using successful scientific theories. If quantum theory correctly describes the structure of the physical world, and if quantum theoretic inferences about which measurement outcomes will be observed with unit probability count as knowledge, we demonstrate that constructivism cannot be upheld. Our derivation is compatible with both intuitionistic and quantum propositional logic. (...) This result is implied by the Frauchiger-Renner theorem, though it is of independent importance as well.

In the paper we look into the epistemology of quantum theory. The starting point is the previously established mathematical ambiguity. The perspective of our study is the way that Schrödinger described Einstein’s idea of physics epistemology. Namely, physical theory is a map with flags. Each flag must, according to Einstein in Schrödinger’s representation, correspond to a physical reality and vice versa. With the ambiguity transformed to quantum-like operators we are able to mimic quantum theory. Therefore (...) we have created little flags. The question is raised whether nature itself is ambiguous. The created flags point at ambiguous nature. Or, nature is not ambiguous and the ambiguity can be repaired in mathematics. (shrink)

This article is the preface to the Russian translation of my Kuhn vs Popper. I use it as an opportunity to re-examine the difference between Kuhn and Popper on the nature of ‘revolutions’ in science. Kuhn is rightly seen as a ‘reluctant revolutionary’ and Popper a ‘permanent revolutionary’. In this respect, Kuhn sticks to the original medieval meaning of ‘revolution’ as restoration of a natural order, whereas Popper adopts the more modern meaning of ‘revolution’ that comes into fashion after the (...) French Revolution, which suggests a radical renewal. A key to understanding this difference in revolutionary mentalities lies in Kuhn’s and Popper’s respective treatment of the ‘Gestalt switch’ phenomenon. Kuhn sees the ambiguous Gestalt figure from the standpoint of the subject, and Popper from that of the experimenter. Behind this difference lies alternative interpretations of the significance of quantum mechanics for scientific epistemology, a preoccupation that Kuhn and Popper shared with the original Gestalt psychologists and is beginning engage the interest of social scientists.

This book explores the prospects of rivaling ontological and epistemic interpretations of quantum mechanics (QM). It concludes with a suggestion for how to interpret QM from an epistemological point of view and with a Kantian touch. It thus refines, extends, and combines existing approaches in a similar direction. -/- The author first looks at current, hotly debated ontological interpretations. These include hidden variables-approaches, Bohmian mechanics, collapse interpretations, and the many worlds interpretation. He demonstrates why none of these ontological interpretations (...) can claim to be the clear winner amongst its rivals. Next, coverage explores the possibility of interpreting QM in terms of knowledge but without the assumption of hidden variables. It examines QBism as well as Healey’s pragmatist view. The author finds both interpretations or programs wanting in certain respects. As a result, he then goes on to advance a genuine proposal as to how to interpret QM from the perspective of an internal realism in the sense of Putnam and Kant. -/- The book also includes two philosophical interludes. One details the notions of probability and realism. The other highlights the connections between the notions of locality, causality, and reality in the context of violations of Bell-type inequalities. (shrink)

Definitions I presented in a previous article as part of a semantic approach in epistemology assumed that the concept of derivability from standard logic held across all mathematical and scientific disciplines. The present article argues that this assumption is not true for quantum mechanics (QM) by showing that concepts of validity applicable to proofs in mathematics and in classical mechanics are inapplicable to proofs in QM. Because semantic epistemology must include this important theory, revision is necessary. The (...) one I propose also extends semantic epistemology beyond the ‘hard’ sciences. The article ends by presenting and then refuting some responses QM theorists might make to my arguments. (shrink)

We interpret the philosophy of Niels Bohr as related to the so called ''linguistic turn'' and consider paraconsistency in the light of the Bohrian notion of complementarity. Following [16], Jean-Yves Beziau has discussed the seemingly contradictory perspectives found in the quantum mechanical double slit experiment in terms of paraconsistent view-points [7, 8]. This interpretation goes in line with the well known Bohrian Neo-Kantian epistemological account of quantum mechanics. In the present paper, we put forward the idea that one (...) can also consider, within quantum mechanics and departing from the philosophy of the danish physicist, a more radical paraconsistency found within one of the main formal elements of the theory, namely, quantum superpositions. We will argue that, rather than epistemological, the contradictions found within quantum superpositions could be interpreted as ontological contradictions. (shrink)

In this paper we investigate the history of relationalism and its present use in some interpretations of quantum mechanics. In the first part of this article we will provide a conceptual analysis of the relation between substantivalism, relationalism and relativism in the history of both physics and philosophy. In the second part, we will address some relational interpretations of quantum mechanics, namely, Bohr’s relational approach, the modal interpretation by Kochen, the perspectival modal version by Bene and Dieks and (...) the relational interpretation by Rovelli. We will argue that all these interpretations ground their understanding of relations in epistemological terms. By taking into account the analysis on the first part of our work, we intend to highlight the fact that there is a different possibility for understanding quantum mechanics in relational terms which has not been yet considered within the foundational literature. This possibility is to consider relations in ontological terms. We will argue that such an understanding might be capable of providing a novel approach to the problem of representing what quantum mechanics is really talking about. (shrink)

The concepts of measurement and measurable quantity are discussed. A probabilistic interpretation independent of the arrow of time is recommended and a definition of quantizable physical systems is given. The space of states of information about the physical system is Schwarz space rather than Hilbert space.

The purpose of this book is to initiate a new discipline, namely a formalized epistemological method drawn from the cognitive strategies practised in the most effective among the modern scientific disciplines, as well as from general philosophical thinking. Indeed, what is lacking in order to improve our knowledge and our domination of the modes which nowadays are available for the generation and communication of knowledge, thoroughly and rapidly and with precision and detail? It is a systematic explication of the epistemological (...) essence encrypted in the specialized languages and algorithms of the major modern scientific approaches, a systematic cross-referencing of the explicated results, and a final elaboration of a new coherent whole. Quantum mechanics, like a diver, can take us down to the level of the very first actions of our conceptualization of reality. And starting from there, it can induce an explicit understanding of certain fundamental features of the new scientific thinking. A formalized epistemology should not be mistaken for a crossdisciplinary or a multidisciplinary project. The latter projects are designed to offer to nonspecialists access to information, to results obtained inside specialized disciplines, as well as a certain understanding of these results; whereas a formalized epistemology should equip anyone with a framework for conceptualizing himself in whatever domain and direction he or she might choose. A formalized epistemology should not be mistaken either for an approach belonging to the modern cognitive sciences. These try to establish as neutrally as possible descriptions of how the human body-and-mind work spontaneously when knowledge is generated; whereas a method of conceptualization should establish what conceptual-operational deliberate procedures have to be applied in order to represent and to achieve processes of generation of knowledge optimized accordingly to any definite aims. This book addresses philosophers of science, physicists, mathematicians, logicians, computer scientists, researchers in cognitive sciences, and biologists, as well as any intellectual who is interested in scientific and philosophical thinking.

Although contemporary analytic epistemology continues to be dominated by externalist accounts, an alternative internalist approach has recently emerged that emphasizes the epistemic role of consciousness, in particular of conscious experience. According to the phenomenological experience-first epistemology (PEFE) discussed in this paper, certain experiences constitute a source of immediate justification as well as our ultimate evidence. One reason why internalist approaches are less popular in current debates is the common assumption that externalism fits better with scientific practice. In this (...) picture, the natural sciences are typically understood as adopting a third-person perspective that successfully abstracts away from the subject and her personal experiences. Here, I discuss an alternative view of science, namely science as understood within the framework of agent-centered approaches to quantum mechanics. More specifically, my focus will be on QBism, a highly controversial but increasingly popular interpretation of quantum mechanics, whose defining feature is the interpretation of quantum probabilities as subjective Bayesian probabilities. The objective of this paper is to clarify the relationship between epistemology and science under the assumption that both PEFE and QBism are correct. (shrink)

We can easily verify that the development of the main theories of knowledge in the modern period of Western philosophy was closely related to the status quo of the development of mathematics and science in a general way. This characteristic is especially evident in the Kantian project of providing the philosophical basis to explain the possibility of (Euclidean) geometry and Newtonian physics, which Kant based on principles which he considered sine qua non conditions of human knowledge. However, the physics that (...) have developed in the first half of the 20th century presented situations in which physicists themselves had to question themselves about the epistemological problems involved in the description, interpretation, and ultimately, in the communication of observed phenomena, so that some concepts dear to traditional epistemology proved to be either invalid or inefficient to explain the possibility of objective knowledge in the face of this new set of phenomena. Therefore, we would like to briefly present how this contrast between traditional epistemology and quantum theory occurs, as well as how physicists Niels Bohr and Werner Heisenberg dealt with the new situation that was presented.

From the very beginning it was realised that quantum physics involves radically new interpretative and epistemological consequences.

The contributions in the present volume review the interpretative situation, analyze recent fundamental experiments, and discuss the implications of possible future technological applications. (...)

Among several possibilities for what reality could be like in view of the empirical facts of quantum mechanics, one is provided by theories of spontaneous wave function collapse, the best known of which is the Ghirardi–Rimini–Weber theory. We show mathematically that in GRW theory there are limitations to knowledge, that is, inhabitants of a GRW universe cannot find out all the facts true of their universe. As a specific example, they cannot accurately measure the number of collapses that a (...) given physical system undergoes during a given time interval; in fact, they cannot reliably measure whether one or zero collapses occur. Put differently, in a GRW universe certain meaningful, factual questions are empirically undecidable. We discuss several types of limitations to knowledge and compare them with those in other versions of quantum mechanics, such as Bohmian mechanics. Most of our results also apply to observer-induced collapses as in orthodox quantum mechanics. 1 Introduction1.1 Known examples of limitations to knowledge1.2 Remarks2 Brief Review of GRW Theories2.1 The GRW process2.2 GRWm2.3 GRWf3 First Examples of Limitations to Knowledge in GRW Theories4 Measurements of Flashes in GRWf, or of Collapses in GRWm4.1 An example in which ψ is known4.2 Other choices of ψ4.3 Experiments beginning before t24.4 If ψ is random4.5 Optimal way of distinguishing two density matrices4.6 If ψ is unknown5 Measurements of m in GRWmAppendix.

Philosophy of science and, more specifically, philosophy of quantum physics can be but special fields of a general philosophy of knowledge; and the problems arising in these fields can be evaluated properly only when they are seen under the perspective of the whole range of human knowledge.

The argument of the paper, however, has not been stated before in the direct and concise manner here attempted and may therefore contain elements of novelty even for those readers who are familiar with the books just mentioned.

After an outline of the macrorealistic solutions to the difficulties of the measurement theory, a new paradox is proposed and then discussed in the light of three different interpretations of quantum mechanics.

The cognition of quantum processes raises a series of questions about ordering and information connecting the states of one and the same system before and after measurement: Quantum measurement, quantum in-variance and the non-locality of quantum information are considered in the paper from an epistemological viewpoint. The adequate generalization of ‘measurement’ is discussed to involve the discrepancy, due to the fundamental Planck constant, between any quantum coherent state and its statistical representation as a statistical ensemble (...) after measurement. Quantum in-variance designates the relation of any quantum coherent state to the corresponding statistical ensemble of measured results. A set-theory corollary is the curious in-variance to the axiom of choice: Any coherent state excludes any well-ordering and thus excludes also the axiom of choice. However the above equivalence requires it to be equated to a well-ordered set after measurement and thus requires the axiom of choice for it to be able to be obtained. Quantum in-variance underlies quantum information and reveals it as the relation of an unordered quantum “much” (i.e. a coherent state) and a well-ordered “many” of the measured results (i.e. a statistical ensemble). It opens up to a new horizon, in which all physical processes and phenomena can be interpreted as quantum computations realizing relevant operations and algorithms on quantum information. All phenomena of entanglement can be described in terms of the so defined quantum information. Quantum in-variance elucidates the link between general relativity and quantum mechanics and thus, the problem of quantum gravity. The non-locality of quantum information unifies the exact position of any space-time point of a smooth trajectory and the common possibility of all space-time points due to a quantum leap. This is deduced from quantum in-variance. Epistemology involves the relation of ordering and thus a generalized kind of information, quantum one, to explain the special features of the cognition in quantum mechanics. (shrink)

If consciousness emerges into ontological reality at some point in nature, as system complexity increases, then it also ‘submerges’ at some adjoining point, as structures simplify. This has led some to posit a ‘latent-consciousness’ in what Bohr saw as the consciousness-like spontaneity of quantum phenomena. Yet to move on this basis to Whitehead's ontological pan-experientialism or to direct quantum explanations of consciousness faces serious epistemological limitations -- perhaps being more unwittingly projective than genuinely explanatory. More reasonable would be (...) an epistemological pan- experientialism in the sense of the later James. Consciousness, as the ultimate lens and medium of all knowledge, is inseparable from the physical reality it would know, especially at the very limits of empirical observation in microphysics. ‘Submerged’ consciousness is better understood in Jamesian pragmatic terms than via assumed but unprovable ontologies.

We argue about a conceptual approach to quantum formalism. Starting from philosophical conjectures (Platonism, Idealism and Realism) as basic ontic elements (namely: math world, data world, and state of matter), we will analyze the quantum superposition principle. This analysis bring us to demonstrate that the basic assumptions affect in different ways:(a) the general problem of the information and computability about a system, (b) the nature of the math tool utilized and (c) the correspondent physical reality.

Since the very begining of quantum theory there started a debate on the proper role of space and time in it. Some authors assumed that space and time have their own algebraic operators. On that basis they supposed that quantum particles had “coordinates of position”, even though those coordinates were not possible to determine with infinite precision. Furthermore, time in quantum physics was taken to be on an equal foot, by means of a so-called “Heisenberg’s fourth relation (...) of indeterminacy” concerning time and energy. In this paper, the proper role of space and time in the core of non-relativistic quantum phsysics is analyzed. We will find that, rigorously, that relation for time and energy shows a different root. For the role of space, it will be discussed that there is no “coordinate of position” in the conceptual structure of quantum physics because quantum particles are not point-like objects. (shrink)

The present article discusses shared epistemological characteristics of two distinct areas of research: the field of first-person inquiry and the field of quantum mechanics. We outline certain philosophical challenges that arise in each of the two lines of inquiry, and point towards the central similarity of their observational situation: the impossibility of disregarding the interrelatedness of the observed phenomena with the act of observation. We argue that this observational feature delineates a specific category of research that we call the (...) non-trivial domain. Unlike the trivial domain, non-trivial research cannot assume the view from nowhere on which the observed phenomena could be regarded as existing independently of the process of observation. Presenting first-person inquiry and quantum mechanics as two of its examples, we show that non-trivial research violates several fundamental observational presuppositions of the trivial domain, exemplified in the principles of classical physics. Drawing on Niels Bohr’s philosophy of quantum mechanics and the constructivist notion of enaction, we stress the constructive, participatory, and irreversible nature of observation in the non-trivial domain. We discuss the possibility of developing a non-representationalist epistemology of the non-trivial, and consider the implications of our discussion for research in the non-trivial domain, as well as for the general understanding of the scientific inquiry.

Bell introduces local beables in contrast to quantum mechanical observables. The present article emphasizes the importance and necessity of introducing local beables in quantum mechanics from the ontological and epistemological points of view. We argue that suggesting beables in the ontology of quantum mechanics is necessary to give an adequate account of its testability.

In this contribution, the role of epistemology in understanding quantum chemistry is discussed. Quantum chemistry is the study of the behavior of atoms and molecules using the principles of quantum mechanics. Epistemology helps us evaluate claims to knowledge, distinguish between justified and unjustified beliefs, and assess the reliability of scientific methods. In quantum chemistry, the epistemology of knowledge is heavily influenced by the mathematical nature of quantum mechanics, and models can be tested, (...) proven, and validated through experimentation. This paper also discusses key concepts used in quantum chemistry, such as the wave-particle duality of matter and the uncertainty principle. This work utilizes Kant’s philosophy of science to frame debates and discussions in quantum chemistry, particularly with regard to the interplay between empirical observation and theory. Additionally, the text explores how Kant’s ideas about the role of the mind in constructing our understanding of the world can help us comprehend the counterintuitive phenomena of quantum mechanics and its applications in quantum chemistry theory.

A rather recent interpretation of quantum mechanics, known under the various names of consistent histories, decohering histories, or logical interpretation, has brought interpretation into a standard deductive theory and is now investigated in many places. A key difference with the Copenhagen interpretation is the status of classical physics, now derived completely from quantum principles in both its dynamical and logical aspects. After describing briefly this new interpretation in its essentials, leaving aside technical details, it is shown how its (...) consequences in epistemology differ drastically from the familiar outcomes of the Copenhagen interpretation, leading in particular to a well-defined theory of knowledge. Some more speculative philosophical consequences associated with the unsolved problem of actuality are also mentioned. (shrink)

This paper examines the epistemological significance of the present situation of underdetermination in quantum mechanics. After analyzing this underdetermination at three levels---formal, ontological, and methodological---the paper considers implications for a number of variants of the thesis of scientific realism in fundamental physics and reassesses Lakatos‘ characterization of progress in physical theory in light of the present situation. Next, this paper considers the implications of underdetermination for Weinberg’s ‘‘dream of a final theory.’’ Finally, the paper concludes by suggesting how one (...) might still think of realism and progress in fundamental physics despite the possibility of persistent underdetermination in quantum mechanics.

In settler-colonial Canada, the state does not receive Indigenous testimony as credible evidence. While the state often accepts Indigenous testimony in formal hearings, the state fundamentally rejects Indigenous evidence as a description of the world as it is, as an onto-epistemology. In other words, the Indigenous worldview formation, while it functions as a knowledge system that knows and predicts life, is not admitted to regulatory discussions about effects of resource extraction projects on life. Particularly in such resource-extraction review hearings, (...) partly for obvious reasons of ecological ethics, there is no space for Indigenous relational-ontology. I theorize that beyond racism, white supremacy, and greed, settler-colonial onto-epistemological structures are structured to systematically eliminate the potential for relational-ontologies. This exclusion is complementary to resource-extractivist and legal positivist procedures and is biased against Indigenous knowledge and knowledge-sharing procedures; it is a crisis of state integrity and is philosophically unsound. In my analysis of Canadian National Energy Board documents, I ferret out some of these structures that de facto discredit Indigenous onto-epistemologies; I propose this fundamental problem of the Canadian settler-colonial state must be recognized and changed if the calls of Canada’s Truth and Reconciliation commission are to be met.

We note, for instance, that the informational view of quantum mechanics (primacy of the subjectivity) is due mainly to the evidence of the "random" physical quantities as ontic element. (...)

I investigate the relationship between traditional philosophical epistemology and cognitive science. I start my considerations with the following questions: does the development of cognitive science require any revision of epistemology, akin to the revision required in some areas analytic philosophy after the emergence of quantum physics? Does cognitive science continue philosophical epistemology or is the complete break with traditional philosophical approaches?

In this article, after a historical introduction, we give an epistemological point of view of the physics of complex systems. Complex systems are epistemologically interesting because of the fundamental interaction experiment/observer and physicists in their everyday life can experience the paradoxes given by this interaction. Here we describe some of these paradoxes, we make a parallel with quantum mechanics and give a possible philosophical solution, based on notorious physicists/philosopher from the past, transposing and reinterpreting their ideas to modern times. (...) In particular, we analyse the interaction with a complex system such as the living cell, and therefore we also analyse some biophysical implications of complexity. (shrink)

First, this article considers the nature of quantum reality and the concept of realism in quantum theory, in conjunction with the roles of locality, causality, and probability and statistics there. Second, it offers two interpretations of quantum mechanics, developed by the authors of this article, the second of which is also a different theory of quantum phenomena. Both of these interpretations are statistical. The first interpretation, by A. Plotnitsky, “the statistical Copenhagen interpretation,” is nonrealist, insofar as (...) the description or even conception of the nature of quantum objects and processes is precluded. The second, by A. Khrennikov, is ultimately realist, because it assumes that the quantum-mechanical level of reality is underlain by a deeper level of reality, described, in a realist fashion, by a model, based in the pre-quantum classical statistical field theory, the predictions of which reproduce those of quantum mechanics. Moreover, because the continuous fields considered in this model are transformed into discrete clicks of detectors, experimental outcomes in this model depend on the context of measurement in accordance with N. Bohr’s interpretation and the statistical Copenhagen interpretation, which coincides with N. Bohr’s interpretation in this regard. (shrink)

For many among the scientifically informed public, and even among physicists, Heisenberg's uncertainty principle epitomizes quantum mechanics. Nevertheless, more than 86 years after its inception, there is no consensus over the interpretation, scope, and validity of this principle. The aim of this chapter is to offer one such interpretation, the traces of which may be found already in Heisenberg's letters to Pauli from 1926, and in Dirac's anticipation of Heisenberg's uncertainty relations from 1927, that stems form the hypothesis of (...) finite nature. Instead of a mere mathematical theorem of quantum theory, or a manifestation of "wave-particle duality", the uncertainty relations turn out to be a result of a more fundamental premise, namely, the inherent limitation on spatial resolution that follows from the bound on physical resources. The implication of this view are far reaching: it depicts the Hilbert space formalism as a phenomenological, "effective", formalism that approximates an underlying discrete structure; it supports a novel interpretation of probability in statistical physics that sees probabilities as deterministic, dynamical transition probabilities which arise from objective and inherent measurement errors; and it helps to clarify several puzzles in the foundations of statistical physics, such as the status of the "disturbance" view of measurement in quantum theory, or the tension between ontology and epistemology in the attempts to describe nature with physical theories whose formalisms include subjective probabilities. Finally, this view also renders obsolete the entire class of interpretations of quantum theory that adhere to "the reality of the wave function". (shrink)

Many current problems surrounding science revolve around the complex epistemological framework that shapes a new vision of knowledge about reality. The traditional epistemological positions are characterized by the explanation of nature by means of concatenated facts; that is, as bricks attached to each other giving shape to the edifice of science. A conception of this nature showed that the idea of certainty was nothing more than a mere illusion, opening the way, on the contrary, to the idea of the uncertainty (...) of knowledge based on the descriptions of quantum physics, also a product of the non-reductionist conception of reality, thus criticizing the specular representation. This article addresses the main problems surrounding the critical conceptions that the emerging epistemology reveals about knowledge, pointing towards a much more complex vision of reality. (shrink)

Discussions related to the detection of objective reality, the truth and lie are still a heated topic in the domain of philosophical epistemology. While certain philosophical contexts and theories suggest that the notion "reality as an independent category" should not be engaged, instead, interpretations, including reciprocal, should be used, others hold it that philosophical discussion cannot continue without reference to the said notion. Different philosophers and scolars approach this problem from different angles. When discussing these topics, philosophers often resort (...) to certain thought experiments, engaging an important concept, which can broadly be identified as "the global observer." This concept has something in common with such concepts as the God's Eye, Omniscient Interpreter, Ultimate Observer (quantum physics), Agent of Logical omniscience (game theories), Ideal Observer (ethics and meta-ethics), God (analytic theology). Despite the abundance of works on the topic and scrupulosity of arguments, there still remain many uncertainties in such discussions, mostly related to a great number of logical paradoxes, associated with the problem. Therefore, in view of the current situation, the focus of the research paper is on the deliberation of consistency of the notion "global observer" from the standpoint of logic and philosophy. The results of the analysis of the issue at stake are expected to clarify the notion and to enrich current discussions on the topic. I examine certain difficulties in the philosophical assumptions concerning one of the philosophical concepts, which could be collectively named as the "global observer." The article below explores the notion of the global observer as the guarantor of the determinability and configuration of events in the world. There is explained the meaning of this concept and attempt to show that, despite variations in the wording, it is used in many philosophical contexts related to epistemology.

Many commentators have remarked in passing on the resonance between deconstructionist theory and certain ideas of quantum physics. In this book, Arkady Plotnitsky rigorously elaborates the similarities and differences between the two by focusing on the work of Niels Bohr and Jacques Derrida. In detailed considerations of Bohr's notion of complementarity and his debates with Einstein, and in analysis of Derrida's work via Georges Bataille's concept of general economy, Plotnitsky demonstrates the value of exploring these theories in relation to (...) each other. Bohr's term complementarity describes a situation, unavoidable in quantum physics, in which two theories thought to be mutually exclusive are required to explain a single phenomenon. Light, for example, can only be explained as both wave and particle, but no synthesis of the two is possible. This theoretical transformation is then examined in relation to the ways that Derrida sets his work against or outside of Hegel, also resisting a similar kind of synthesis and enacting a transformation of its own. Though concerned primarily with Bohr and Derrida, Plotnitsky also considers a wide range of anti-epistemological endeavors including the work of Nietzsche, Bataille, and the mathematician Kurt Gödel. Under the rubric of complementarity he develops a theoretical framework that raises new possiblilities for students and scholars of literary theory, philosophy, and philosophy of science. (shrink)
