  1. Does von Neumann Entropy Correspond to Thermodynamic Entropy?Eugene Y. S. Chua - 2021 - Philosophy of Science 88 (1):145-168.
    Conventional wisdom holds that the von Neumann entropy corresponds to thermodynamic entropy, but Hemmo and Shenker (2006) have recently argued against this view by attacking von Neumann's (1955) argument. I argue that Hemmo and Shenker's arguments fail due to several misunderstandings: about statistical-mechanical and thermodynamic domains of applicability, about the nature of mixed states, and about the role of approximations in physics. As a result, their arguments fail in all cases: in the single-particle case, the finite particles case, (...)

  2. John von Neumann's 'Impossibility Proof' in a Historical Perspective.Louis Caruana - 1995 - Physis 32:109-124.
    John von Neumann's proof that quantum mechanics is logically incompatible with hidden varibales has been the object of extensive study both by physicists and by historians. The latter have concentrated mainly on the way the proof was interpreted, accepted and rejected between 1932, when it was published, and 1966, when J.S. Bell published the first explicit identification of the mistake it involved. What is proposed in this paper is an investigation into the origins of the proof rather than the (...)

  3. Von Neumann's Methodology of Science: From Incompleteness Theorems to Later foundational Reflections.Giambattista Formica - 2010 - Perspectives on Science 18 (4):480-499.
    In spite of the many efforts made to clarify von Neumann’s methodology of science, one crucial point seems to have been disregarded in recent literature: his closeness to Hilbert’s spirit. In this paper I shall claim that the scientific methodology adopted by von Neumann in his later foundational reflections originates in the attempt to revaluate Hilbert’s axiomatics in the light of Gödel’s incompleteness theorems. Indeed, axiomatics continues to be pursued by the Hungarian mathematician in the spirit of Hilbert’s (...)

  4. Oversights in the Respective Theorems of von Neumann and Bell are Homologous.Joy Christian - manuscript
    We show that the respective oversights in the von Neumann's general theorem against all hidden variable theories and Bell's theorem against their local-realistic counterparts are homologous. When latter oversight is rectified, the bounds on the CHSH correlator work out to be ±2√2 instead of ±2.

  5. On the history of the isomorphism problem of dynamical systems with special regard to von Neumann’s contribution.Miklós Rédei & Charlotte Werndl - 2012 - Archive for History of Exact Sciences 66 (1):71-93.
    This paper reviews some major episodes in the history of the spatial isomorphism problem of dynamical systems theory. In particular, by analysing, both systematically and in historical context, a hitherto unpublished letter written in 1941 by John von Neumann to Stanislaw Ulam, this paper clarifies von Neumann's contribution to discovering the relationship between spatial isomorphism and spectral isomorphism. The main message of the paper is that von Neumann's argument described in his letter to Ulam is the very (...)

    Grenzwesen Mensch. Zur systematischen Aktualität von Georg Simmels Kulturphilosophie.Johannes Steizinger - 2020 - Zeitschrift für Kulturphilosophie 14 (2):123–136.
    This paper examines Georg Simmel’s philosophy of culture in relation to anthropological debates, developing a historical and a systematic argument: First, I show that Simmel’s approach can be read as a response to the anthropological challenge of modernity. Second, I demonstrate that Simmel’s theory of culture can be brought to bear on current anthropological debates. Focusing on his concept of cultivation, I argue that Simmel advances a transformative concept of humanity that considers both the biological nature of humans and the (...)

    Zwischen milieu intérieur und medical decision making – Aspekte einer medizinischen Kybernetik.Johannes W. Dietrich - manuscript
    Seit wenigen Jahren erfreuen sich in den Lebenswissenschaften mehrere Theorien eines immer weitergehenden Einflusses, die unter Etikettierungen wie Systembiologie, Netzwerktheorie oder Signalomics nur scheinbar unabhängige Herangehensweisen an komplexe Zusammenhänge darstellen. Navigation ist der übergreifende Gedanke, der so unterschiedliche Gebiete wie Regelungstheorie, Entscheidungstheorie und Systemwissenschaft verbindet.

    Die identitäre Ideologie. Wiederkehr des völkischen Denkens.Johannes Steizinger - 2018 - Perspektiven DS 35 (2):77-79.
    Nationalistische Ideen haben in der gegenwärtigen Politik Konjunktur. Dabei ist auch die Wiederkehr einer völkisch-traditionalistischen Ideologie zu beobachten. Der völkische Nationalismus ist in rechtsextremen Gruppen weit verbreitet. Mittlerweile wirken völkische Ideen jedoch weit in die bürgerliche Mitte hinein, nicht zuletzt aufgrund der erfolgreichen Strategien der sogenannten „Neuen Rechten“. Die Identitäre Bewegung (IB) spielt in dieser Szene eine wesentliche Rolle und wird zumeist als eine „neurechte Jugendbewegung“ (Bruns et al 2017) definiert. Diese Einschätzung möchte ich im Folgenden näher betrachten. Meine Auseinandersetzung (...)

    Die Semiotik der Gesellschaft: Skizze einer semiotisch-pragmatischen Theorie der Gesellschaft.Johannes Ehrat - 2007 - Gregorianum 88 (3):619-642.
    Gesellschaft ist ein schwieriger, weil prinzipiell nie konkret faßbarer Gegenstand der Erkenntnis. Zu diesem Problem gibt es u.a. transzendentale, phänomenologische, systemtheoretische Ansätze. Die Gegenstandsverfassung hat weitreichende forschungspraktische Konsequenzen, auch hinsichtlich sozialwissenschaftlicher Wissenschaftlichkeit. Pragmatismus und Semiotik fand, trotz Apels Peirce- und Joas’ Meadrezeption, noch nicht genügend Beachtung. Gesellschaft wird nicht als Objekt, sondern als erkenntnisdeterminierendes Ziel eines kognitiven Verhaltens eingeführt. Sie wird so kontextualisiert in einer Wahrheitstheorie, die sowohl objektive Fakten wie kognitive Allgemeinheit in sich vereint, und zwar konkret in jeder (...)

    Wydane w latach 1782-1786 Niemieckie baśnie ludowe Johanna Karla Augusta Musausa, znanego oświeceniowej publiczności autora poczytnych Podróży fizjognomicznych, przyjęto początkowo entuzjastycznie, uznając je za wyjątkowo udaną formę literaryzacji elementów baśniowej tradycji ustnej i pisanej oraz podkreślając walory "dowcipnej" narracji. W wieku XVIII pojęcie "baśni" (Miirchen) miało szerokie znaczenie. Słowniki i leksykony wskazują na to, iż pojęcia: "bajka" (Fabel), "baśń" (Mcirchen), "podanie" (Sage) i "legenda"(Legende) mogły być używane zamiennie.

    Kurz bevor Goethe in den Jahren 1808/9 die Wahlverwandtschaften schrieb, hatte sich sein ehemaliger naturwissenschaftlicher Kooperationspartner Johann Ritter in Untersuchungen zu Wünschelruten und Pendeln (1807/8) verloren, aus denen angeblich eine weitere tiefgreifende Analogie zwischen den Polaritäten in der Natur und denen beim Menschen hervorgehen sollte. Ritter arbeitete damals schon seit Jahren erfolgreich mit Goethes Polaritätsbegriff, und war dadurch sogar auf seinen größten Erfolg geleitet worden (die Entdeckung des UV-Lichts). So ist es nicht überraschend, dass sich Goethe für die Pendelexperimente (...)

    What does it mean to be conservative? What could it mean in the arts? Whoever merely conserves works of art may be a collector but is not an artist. Brahms’s trio op. 40 conserves the hand horn idiom. Yet its aesthetics will not be captured by the opposition of ‘conservative’ versus ‘progressive’. What is superior in terms of technology, Brahms maintained, need not be superior in terms of art.

  29. A Reconsideration of the Harsanyi–Sen–Weymark Debate on Utilitarianism.Hilary Greaves - 2016 - Utilitas:1-39.
    Harsanyi claimed that his Aggregation and Impartial Observer Theorems provide a justification for utilitarianism. This claim has been strongly resisted, notably by Sen and Weymark, who argue that while Harsanyi has perhaps shown that overall good is a linear sum of individuals’ von Neumann-Morgenstern utilities, he has done nothing to establish any con- nection between the notion of von Neumann-Morgenstern utility and that of well-being, and hence that utilitarianism does not follow. The present article defends Harsanyi against the (...)

  30. Prioritarianism and the Measure of Utility.Michael Otsuka - 2015 - Journal of Political Philosophy 23 (1):1-22.
    I argue that prioritarianism cannot be assessed in abstraction from an account of the measure of utility. Rather, the soundness of this view crucially depends on what counts as a greater, lesser, or equal increase in a person’s utility. In particular, prioritarianism cannot accommodate a normatively compelling measure of utility that is captured by the axioms of John von Neumann and Oskar Morgenstern’s expected utility theory. Nor can it accommodate a plausible and elegant generalization of this theory that has (...)

    In the first part of his magnum opus Hans Urs von Balthasarpresents his project of theological aesthetics where the experience of art becomes an entrance to a religious act and an ennobling way leading to the contemplation of God. Defining the essence of being human as a spiritual being directed towards God bears a deep ethical meaning in this consideration. H.U. von Balthasar’s reflection over the religious dimension of the essence of art is shaped within theology but at the same (...)

    Phenomenological reflection on the essence of art goes towards the revelation of its ultimate Source, which is also the Source of spirituality of a man and, finally, of artistic works.

For those philosophers the work of art is a ‘way’ which may lead (...)

  34. Set Theory, Topology, and the Possibility of Junky Worlds.Thomas Mormann - 2014 - Notre Dame Journal of Formal Logic 55 (1): 79 - 90.
    A possible world is a junky world if and only if each thing in it is a proper part. The possibility of junky worlds contradicts the principle of general fusion. Bohn (2009) argues for the possibility of junky worlds, Watson (2010) suggests that Bohn‘s arguments are flawed. This paper shows that the arguments of both authors leave much to be desired. First, relying on the classical results of Cantor, Zermelo, Fraenkel, and von Neumann, this paper proves the possibility of (...)

    We review our approach to quantum mechanics adding also some new interesting results. We start by giving proof of two important theorems on the existence of the A(Si) and i,±1 N Clifford algebras. This last algebra gives proof of the von Neumann basic postulates on the quantum measurement explaining thus in an algebraic manner the wave function collapse postulated in standard quantum theory. In this manner we reach the objective to expose a self-consistent version of quantum mechanics. In detail (...)

    Ancient Greek philosophers were the first to postulate the possibility of explaining nature in theoretical terms and to initiate attempts at this. With the rise of monotheistic religions of revelation claiming supremacy over human reason and envisaging a new world to come, studies of the natural order of the transient world were widely considered undesirable. Later, in the Middle Ages, the desire for human understanding of nature in terms of reason was revived. This article is concerned with the fundamental reversal (...)

  37. Consciousness and the Collapse of the Wave Function.David J. Chalmers & Kelvin J. McQueen - 2022 - In Shan Gao (ed.), Consciousness and Quantum Mechanics. Oxford University Press, Usa.
    Does consciousness collapse the quantum wave function? This idea was taken seriously by John von Neumann and Eugene Wigner but is now widely dismissed. We develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. In principle, versions of the theory can be tested by experiments (...)

  39. Making sense of ‘genetic programs’: biomolecular Post–Newell production systems.Mihnea Capraru - 2024 - Biology and Philosophy 39 (2):1-12.
    The biomedical literature makes extensive use of the concept of a genetic program. So far, however, the nature of genetic programs has received no satisfactory elucidation from the standpoint of computer science. This unsettling omission has led to doubts about the very existence of genetic programs, on the grounds that gene regulatory networks lack a predetermined schedule of execution, which may seem to contradict the very idea of a program. I show, however, that we can make perfect sense of genetic (...)

    People with the kind of preferences that give rise to the St. Petersburg paradox are problematic---but not because there is anything wrong with infinite utilities. Rather, such people cannot assign the St. Petersburg gamble any value that any kind of outcome could possibly have. Their preferences also violate an infinitary generalization of Savage's Sure Thing Principle, which we call the *Countable Sure Thing Principle*, as well as an infinitary generalization of von Neumann and Morgenstern's Independence axiom, which we call (...)

    Since John Von Neumann's proposition in 1932 of a relationship between quantum mechanics and the brain, different perspectives and proposals have evolved (Tarlaci, 2010). Hu & Wu (2006) point out that the seat of consciousness would be the spin within the membranes of neurons and proteins in the brain. Sieb (2016) applied the theory of relativity to spatiotemporal consciousness and found correlations with aspects of brain functioning. Another suggestion is that consciousness emerges because of the Orchestrated Objective Reduction in (...)

  42. Feyerabend on the Quantum Theory of Measurement: A Reassessment.Daniel Kuby & Patrick Fraser - 2022 - International Studies in the Philosophy of Science 35 (1):23-49.
    In 1957, Feyerabend delivered a paper titled ‘On the Quantum-Theory of Measurement’ at the Colston Research Symposium in Bristol to sketch a completion of von Neumann's measurement scheme without collapse, using only unitary quantum dynamics and well-motivated statistical assumptions about macroscopic quantum systems. Feyerabend's paper has been recognised as an early contribution to quantum measurement, anticipating certain aspects of decoherence. Our paper reassesses the physical and philosophical content of Feyerabend's contribution, detailing the technical steps as well as its overall (...)

    Could a sufficiently detailed computer simulation of consciousness replicate consciousness? In other words, is performing the right computations sufficient for artificial consciousness? Or will there remain a difference between simulating and being a conscious system, because the right computations must be implemented in the right way? From the perspective of Karl Friston's free energy principle, self-organising systems (such as living organisms) share a set of properties that could be realised in artificial systems, but are not instantiated by computers with a (...)

  45. There’s Plenty of Boole at the Bottom: A Reversible CA Against Information Entropy.Francesco Berto, Jacopo Tagliabue & Gabriele Rossi - 2016 - Minds and Machines 26 (4):341-357.
    “There’s Plenty of Room at the Bottom”, said the title of Richard Feynman’s 1959 seminal conference at the California Institute of Technology. Fifty years on, nanotechnologies have led computer scientists to pay close attention to the links between physical reality and information processing. Not all the physical requirements of optimal computation are captured by traditional models—one still largely missing is reversibility. The dynamic laws of physics are reversible at microphysical level, distinct initial states of a system leading to distinct final (...)

  46. Quantum Theories of Consciousness.Paavo Pylkkänen - 2018 - In Rocco J. Gennaro (ed.), Routledge Handbook of Consciousness. New York: Routledge. pp. 216-231.
    This paper provides a brief introduction to quantum theory and the proceeds to discuss the different ways in which the relationship between quantum theory and mind/consciousness is seen in some of the main alternative interpretations of quantum theory namely by Bohr; von Neumann; Penrose: Everett; and Bohm and Hiley. It briefly considers how qualia might be explained in a quantum framework, and makes a connection to research on quantum biology, quantum cognition and quantum computation. The paper notes that it (...)

  47. Killing Schrodinger's Cat: Why Macroscopic Quantum Superpositions Are Impossible In Principle.Andrew Knight - manuscript
    The Schrodinger's Cat and Wigner's Friend thought experiments, which logically follow from the universality of quantum mechanics at all scales, have been repeatedly characterized as possible in principle, if perhaps difficult or impossible for all practical purposes. I show in this paper why these experiments, and interesting macroscopic superpositions in general, are actually impossible in principle. First, no macroscopic superposition can be created via the slow process of natural quantum packet dispersion because all macroscopic objects are inundated with decohering interactions (...)

  48. How Academic Opinion Leaders Shape Scientific Ideas: An Acknowledgment Analysis.Catherine Herfeld & Malte Doehne - forthcoming - Scientometrics.
    In this paper, we examine how a research institution’s social structure and academic opinion leaders’ presence shaped the early adoption of a scientific innovation. Our case considers the early engagement of mathematical economists at the Cowles Commission with John von Neumann and Oskar Morgenstern’s Theory of Games and Economic Behavior. We argue that scholars with administrative leadership functions who were not only scientifically but also organizationally central – in our case the director of research Jacob Marschak – played a (...)

  49. The Allais paradox: what it became, what it really was, what it now suggests to us.Philippe Mongin - 2019 - Economics and Philosophy 35 (3):423-459.
    Whereas many others have scrutinized the Allais paradox from a theoretical angle, we study the paradox from an historical perspective and link our findings to a suggestion as to how decision theory could make use of it today. We emphasize that Allais proposed the paradox as a normative argument, concerned with ‘the rational man’ and not the ‘real man’, to use his words. Moreover, and more subtly, we argue that Allais had an unusual sense of the normative, being concerned not (...)
