This dissertation is an attempt to defend two founders of quantum theories, Niels Bohr and Wolfgang Pauli, against various anti-realist readings. These readings claim that Bohr's and Pauli's interpretations of quantum mechanics are based on a denial of the reality of the external world, and that their debates with Albert Einstein are over realism. But I argue that the differences between their views and Einstein's are neither about the reality of the external world, nor about the reality of theoretical entities (...) in general. Rather, the differences are about the reality of this or that particular theoretical entity and the viability of this or that particular idea of physics. Although in 1972 Clifford Hooker gave an adequate and then-comprehensive discussion of Bohr's ideas countering anti-realist readings, his work has been forgotten by a new generation of interpreters such as Arthur Fine and Mara Beller who read anti-realism into Bohr's ideas. One aim of this dissertation is to revive Hooker's defense of Bohr and to counter such misreadings. ;A second contribution this dissertation makes consists in an elaboration of Pauli's views. Pauli wrote extensively on many philosophical issues, and made important contributions to the debates between Einstein, Bohr and himself. However, his views are unfairly ignored by most philosophers of quantum mechanics, and when considered, are at best quickly dismissed as anti-realist. In my dissertation, I discuss Pauli's rich ideas on physics and philosophy and show that Pauli is not an anti-realist. In particular, Bohr's and Pauli's views on a problem introduced in a paper by Einstein, Boris Podolsky, and Nathan Rosen are discussed in detail. The close examination of Bohr's and Pauli's views also shows that there are significant differences between them, suggesting the inadequacy of the generic term "the Copenhagen school," often used to refer indiscriminately to their views. Through my studies of Bohr's and Pauli's ideas, I hope to show the inadequacy of using metaphysical doctrines such as realism and anti-realism to gain either a full understanding of general problems in physics, or an understanding of the ideas of these working physicists in particular.

Niels Bohr was born on October 7, 1885. He was one of the great innovators in physical science in the twentieth century. It so happens that 1985 also marks fifty years since the long discussions, which had begun in the 1920s between Albert Einstein and Bohr on the philosophical problems of quantum physics, attained their apogee. An article co-authored by Einstein, B. Podolsky, and N. Rosen, "Can Quantum Mechanics Be Considered a Complete Description of Physical Reality?," was published in (...) 1935 in the journal Physical Review. According to Bohr, "by virtue of its clarity and, it would seem, flawless argumentation, the work of Einstein, Podolsky, and Rosen has created excitement among physicists and played a great role in the discussion of general philosophical questions of physics." Precisely as a result of the publication of this article, the critical position of Einstein concerning quantum mechanics became known to a broader circle of physicists. In the same year, Bohr responded to Einstein and his co-authors with an article under the same title. (shrink)

In the formation of the multi-disciplinary field that investigates the participation of disabled persons in all forms of physical activity, little ethical and philosophical work has been published. This essay serves to contextualise a range of issues emanating from adapted physical activity (APA) and disability sports. First, we offer some general historical and philosophical remarks about the field which serve to situate those issues at the crossroads between the philosophy of disability and the philosophy of sports. Secondly, we (...) bring brief but critical attention to the contestation of key concepts such as ?ability? and ?normality? and the recent criticisms of polarisation of the medical and social models of disability. Finally, we show how these conceptual issues are implicated in the whole spectrum of contexts of APA and disability sports from the ethics of research with and for the disabled, to coaching, rehabilitation and teaching, and sports administration, that are predicated on key ethical concepts including empathy, entitlement and equity.

Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the detection of the Higgs particle and gravitational waves, and the failure to detect supersymmetry where many expected to find it, question the validity (...) of certain philosophical assumptions common among theoretical physicists, inviting us to engage in a clearer philosophical reflection on scientific method.

This chapter contains sections titled: Milieu Philosophy or Physics? Apprenticeship Starting Research and Minerva From Physics to Philosophy Causality and Levels Teaching Acknowledgment Books by Mario Bunge.

This accessible and engaging text explores the relationship between philosophy, science and physical geography. It addresses an imbalance that exists in opinion, teaching and to a lesser extent research, between a philosophically enriched human geography and a perceived philosophically ignorant physical geography. Science, Philosophy and Physical Geography , challenges the myth that there is a single self-evident scientific method, that can and is applied in a straightforward manner by physical geographers. It demonstrates the variety of alternative philosophical perspectives. (...) Furthermore it emphasizes the difference that the real world geographical context and the geographer make to the study of environmental phenomenon. This includes a consideration of the dynamic relationship between human and physical geography. Finally, it demonstrates the relevance of philosophy for both an understanding of published material and for the design and implementation of studies in physical geography. Key themes such as global warming, species and evolution and fluvial geomorphology are used to provide illustrations of key concepts in each chapter. Further reading is provided at the end of each chapter. (shrink)

In modern philosophy of nature the World is unified and holistic. Cosmic Universe and Human History, microcosm and macrocosm, inorganic and living matter coexist and form a unique unity manifested in multiple forms. The Physical and the Mental constitute the form and the content of the World. The world does not consist of subjects and objects, the “subject” and the “object” are metaphysical abstractions of the single and indivisible Wholeness. Man’s finite knowledge separates the Whole into parts and studies (...) fragmentarily the beings. The Wholeness is manifested in multiple forms and each form encapsulates the Wholeness. The rational explanation of the excerpts and the intuitive apprehension of the Wholeness are required to combine and create the open thought and the holistic knowledge. This means that the measurement should be defined by the ''measure'', but the responsibility for determining the ''measure'' depends on the man. This requires that man overcomes the anthropocentric arrogance and the narcissistic selfishness and he joins the Cosmic World in a friendly and creative manner. (shrink)

Accelerating Expansion explores some of the philosophical implications of modern cosmology, focused on the significance that the discovery of the accelerating expansion of the Universe has for our understanding of time, geometry, and physics. The appearance of the cosmological constant in the equations of general relativity allows one to model universes in which space has an inherent tendency towards expansion. This constant, introduced by Einstein but subsequently abandoned by him, returned to centre stage with the discovery of the accelerating (...) expansion. This pedagogically-oriented essay begins with a study of the most basic and elegant relativistic world that involves a positive cosmological constant, de Sitter spacetime. It then turns to the relatives of de Sitter spacetime that dominate modern relativistic cosmology. Some of the topics considered include: the nature of time and simultaneity in de Sitter worlds; the sense in which de Sitter spacetime is a powerful dynamical attractor; the limited extent to which observation can give us information about the topology of space in a world undergoing accelerated expansion; and cosmologists' favourite sceptical worry about the reliability of evidence and the possibility of knowledge, the problem of Boltzmann brains.

A survey of popular textbooks and websites on philosophy produces a ­remarkable consensus on the great problems facing philosophers from ­ancient to modern times. They typically include metaphysics - what is there?, the problem of knowledge - how do we know what exists?, the mind/body problem - can an immaterial mind move the material body?, the “hard problem” of consciousness, freedom of the will, theories of ethics - is there an objective universal Good?, and problems from theology - does (...) God exist?, is God responsible for evil? This book introduces the Information Philosopher website, a work in progress on several classic questions in philosophy that ­logical positivists and analytic language philosophers thought they could ­­dis-solve as logical puzzles, pseudo-problems, or conceptual errors.

Presents German physicist Werner Heisenberg's 1958 text in which he discusses the philosophical implications and social consequences of quantum mechanics and other physical theories.

Philosophers sometimes hope that our discipline will be transformative for students, perhaps especially when we teach so-called philosophy of the body. To that end, this article describes an experimental upper-level undergraduate course cross-listed between Philosophy and Physical Education, entitled “Thinking Through the Body: Philosophy and Yoga.” Drawing on the perspectives of professor and students, we show how a somatic practice (here, hatha yoga) and reading texts (here, primarily contemporary phenomenology) can be integrated in teaching and learning. We (...) suggest that the course raised questions about the ethics of evaluation as well as about the split between theory and practice, which have larger pedagogical implications. (shrink)

In the 20th century the infiltration of scientific elements into philosophical currents not only reached its maximum, but also science itself became a "philosophical factor". We look at these processes in physics starting from the fall of mechanistic philosophy. The advent of relativity theory and quantum mechanics has changed physics as science and raised a host of philosophical questions. Traditionally philosophical questions concerning space, time and causality cannot be any longer considered with no help of these theories. (...) Relativistic cosmology and its observational successes in the last decades of the century, for the first time in the history of human thought, provided a global framework for both science and philosophy. And the current search for the final unifying theory of physics leads directly to the most foundational questions of an ontological character. We argue that the success of the 20th century physics strongly suggests a kind of structuralist ontology. /// No século XX, a infiltração de elementos científicos nas correntes filosóficas não só alcançou o seu máximo, mas também é verdade que a própria ciência se tornou um "factor filosófico". O presente artigo considera estes processos na física, a começar com a decadência da filosofia mecanicista. O advento da teoria da relatividade e da mecânica quântica transformou a física enquanto ciência e levantou uma plêiade de questões filosóficas. Questões tradicionais acerca do espaço, do tempo e da causalidade não podem mais ser consideradas sem o contributo destas teorias. A cosmologia relati-vista e os seus sucessos observacionais nas últimas décadas do século passado, e isso pela primeira vez na história do pensamento humano, fornecem um esquema global tanto para a ciência como para a filosofia. Além disso, a busca corrente de uma última teoria unificadora da física conduz directamente às questões mais fundacionais de carácter ontológico. O autor do artigo defende que os sucessos da física do século XX sugerem fortemente uma espécie de ontologia estruturalista. (shrink)

Among the great ironies of quantum mechanics is not only that its conceptual foundations seem strange even to the physicists who use it, but that philosophers have largely ignored it. Here, Bernard d'Espagnat argues that quantum physics--by casting doubts on once hallowed concepts such as space, material objects, and causality-demands serious reconsideration of most of traditional philosophy. On Physics and Philosophy is an accessible, mathematics-free reflection on the philosophical meaning of the quantum revolution, by one of (...) the world's leading authorities on the subject. D'Espagnat presents an objective account of the main guiding principles of contemporary physics-in particular, quantum mechanics-followed by a look at just what consequences these should imply for philosophical thinking. The author begins by describing recent discoveries in quantum physics such as nonseparability, and explicating the significance of contemporary developments such as decoherence. Then he proceeds to set various philosophical theories of knowledge--such as materialism, realism, Kantism, and neo-Kantism--against the conceptual problems quantum theory raises. His overall conclusion is that while the physical implications of quantum theory suggest that scientific knowledge will never truly describe mind-independent reality, the notion of such an ultimate reality--one we can never access directly or rationally and which he calls "veiled reality"--remains conceptually necessary nonetheless.

Through both an historical and philosophical analysis of the concept of possibility, we show how including both potentiality and actuality as part of the real is both compatible with experience and contributes to solving key problems of fundamental process and emergence. The book is organized into four main sections that incorporate our routes to potentiality: (1) potentiality in modern science [history and philosophy; quantum physics and complexity]; (2) Relational Realism [ontological interpretation of quantum physics; philosophy and (...) logic]; (3) Process Physics [ontological interpretation of relativity theory; physics and philosophy]; (4) on speculative philosophy and physics [limitations and approximations; process philosophy]. We conclude that certain fundamental problems in modern physics require complementary analyses of certain philosophical and metaphysical issues, and that such scholarship reveals intrinsic features and limits of determinism, potentiality and emergence that enable, among others, important progress on the quantum theory of measurement problem and new understandings of emergence.

Paper presented in the 3rd edition of Bucharest Colloquium on Early Modern Science.

Ruth Glasner presents an illuminating reappraisal of Averroes' physics.

Quantum philosophy, a peculiar twentieth-century malady, is responsible for most of the conceptual muddle plaguing the foundations of quantum physics. When this philosophy is eschewed, one naturally arrives at Bohmian mechanics, which is what emerges from Schrodinger's equation for a nonrelativistic system of particles when we merely insist that 'particles' means particles. While distinctly non-Newtonian, Bohmian mechanics is a fully deterministic theory of particles in motion, a motion choreographed by the wave function. The quantum formalism emerges when (...) measurement situations are analyzed according to this theory. When the quantum formalism is regarded as arising in this way, the paradoxes and perplexities so often associated with quantum theory simply evaporate.Bohr's ... approach to atomic problems ... is really remarkable. He is completely convinced that any understanding in the usual sense of the word is impossible. Therefore the conversation is almost immediately driven into philosophical questions, and soon you no longer know whether you really take the position he is attacking, or whether you really must attack the position he is defending.

Study of realism with special reference to the philosophy of Upanishads and Vedanta.

The essay centers on Godel's views on the place of our intuitive concept of time in philosophy and in physics. It presents my interpretation of his work on the theory of relativity, his observations on the relationship between Einstein's theory and Kantian philosophy, as well as some of the scattered remarks in his conversations with me in the seventies-namely, those of the philosophies of Leibniz, Hegel and Husserl-as a successor of Kant-in relation to their conceptions of time.

In the tense religious climate of the late Renaissance (ca. 1550-1650), traditional charges of impiety directed against Aristotle carried new weight. Many turned to alternative philosophical authorities in the search for a truly pious philosophy. Another, "most pious" solution was to ground natural philosophy on a literal reading of the Bible, especially Genesis. I examine this kind of physics, often called Mosaic, or sacred, or Christian, through the example of Johann Amos Comenius and those whom he praises (...) as predecessors in his attempt to reform physics according to the "divine light" of Scripture. In analyzing the works of these authors, I conclude that what they shared most effectively was an agenda rather than a practice. They defended the single, universal truth of a "Christian philosophy" grounded in biblical literalism against the impious excesses of philosophical naturalism, on the one hand, and against the antiphilosophical attacks of extreme theologians, on the other hand. This peculiar strand of natural philosophy, neither traditional nor "modern," needs to be included in attempts to map the complex dynamics of contemporary debates and self-presentations. -/- .

Aristotle began his great study on causes, which he called Metaphysics, with a simple connection to physics: "All men by nature desire to know. An indication of this is the delight we take in our senses." Catholic high school physics teacher Matt D'Antuono makes a similar connection in his own teaching. While discussing the nature of science with his physics students, Matt pointed out that their topic of conversation was technically not science any more. Instead, when they (...) were talking about the nature of science, they were doing philosophy. The students then wanted Matt to teach them some philosophy, and Philosophy Fridays became a classroom tradition. Every secondary school teacher will find within this book the kind of practical wisdom that enlightens the young mind and engages their students in the act of contemplating all the wonders of our world, both physical and metaphysical.

It has often been claimed that without drastic conceptual innovations a genuine explanation of quantum interference effects and quantum randomness is impossible. This book concerns Bohmian mechanics, a simple particle theory that is a counterexample to such claims. The gentle introduction and other contributions collected here show how the phenomena of non-relativistic quantum mechanics, from Heisenberg's uncertainty principle to non-commuting observables, emerge from the Bohmian motion of particles, the natural particle motion associated with Schrödinger's equation. This book will be of (...) value to all students and researchers in physics with an interest in the meaning of quantum theory as well as to philosophers of science. (shrink)

An essay first published in 1917 presents key insights and ideas that shaped Whitehead’s physics and metaphysics. It also displays his apparently lifelong view that science cut off from philosophy (which for him meant, or at some point led to, metaphysics) will fall short in its vital mission of explaining facts and phenomena—a view dissenting sharply from reigning doctrines of the modem era. His largely implicit criticism of the modem assumption that science as such can do without (...) class='Hi'>philosophy merits clarification and evaluation. (shrink)

This collection of essays by leading philosophers of physics was first published in 2000, and offers philosophical perspectives on two of the central elements of modern physics, quantum theory and relativity.

Reading Bohr: Physics and Philosophy offers a new perspective on Niels Bohr's interpretation of quantum mechanics as complementarity, and on the relationships between physics and philosophy in Bohr's work, which has had momentous significance for our understanding of quantum theory and of the nature of knowledge in general. Philosophically, the book reassesses Bohr's place in the Western philosophical tradition, from Kant and Hegel on. Physically, it reconsiders the main issues at stake in the Bohr-Einstein confrontation and (...) in the ongoing debates concerning quantum physics. It also devotes greater attention than in most commentaries on Bohr to the key developments and transformations of his thinking concerning complementarity. Most significant among them were those that occurred, first, under the impact of Bohr's exchanges with Einstein and, second, under the impact of developments in quantum theory itself, both quantum mechanics and quantum field theory. The importance of quantum field theory for Bohr's thinking has not been adequately addressed in the literature on Bohr, to the considerable detriment to our understanding of the history of quantum physics. Filling this lacuna is one of the main contributions of the book, which also enables us to show why quantum field theory compels us to move beyond Bohr without, however, simply leaving him behind.
