    Collapsing strong emergence’s collapse problem.J. M. Fritzman - 2024 - European Journal for Philosophy of Science 14 (2):1-24.
    It is impossible to deduce the properties of a strongly emergent whole from a complete knowledge of the properties of its constituents, according to C. D. Broad, when those constituents are isolated from the whole or when they are constituents of other wholes. Elanor Taylor proposes the Collapse Problem. Macro-level property p supposedly emerges when its micro-level components combine in relation r. However, each component has the property that it can combine with the others in r to produce p. (...)

  3. Four Tails Problems for Dynamical Collapse Theories.Kelvin J. McQueen - 2015 - Studies in the History and Philosophy of Modern Physics 49:10-18.
    The primary quantum mechanical equation of motion entails that measurements typically do not have determinate outcomes, but result in superpositions of all possible outcomes. Dynamical collapse theories (e.g. GRW) supplement this equation with a stochastic Gaussian collapse function, intended to collapse the superposition of outcomes into one outcome. But the Gaussian collapses are imperfect in a way that leaves the superpositions intact. This is the tails problem. There are several ways of making this problem more precise. But many (...)

  4. Divine Simplicity and Modal Collapse: A Persistent Problem.Ryan Mullins & Shannon Byrd - 2022 - European Journal for Philosophy of Religion 14 (1):21-52.
    In recent years the doctrine of divine simplicity has become a topic of interest in the philosophical theological community. In particular, the modal collapse argument against divine simplicity has garnered various responses from proponents of divine simplicity. Some even claiming that the modal collapse argument is invalid. It is our contention that these responses have either misunderstood or misstated the argument, and have thus missed the force of the objection. Our main aim is to clarify what the modal collapse argument (...)

  5. Wavefunction Collapse and Random Walk.Brian Collett & Philip Pearle - 2003 - Foundations of Physics 33 (10):1495-1541.
    Wavefunction collapse models modify Schrödinger's equation so that it describes the rapid evolution of a superposition of macroscopically distinguishable states to one of them. This provides a phenomenological basis for a physical resolution to the so-called “measurement problem.” Such models have experimentally testable differences from standard quantum theory. The most well developed such model at present is the Continuous Spontaneous Localization (CSL) model in which a universal fluctuating classical field interacts with particles to cause collapse. One “side effect” of (...)

    Collapse theories.Giancarlo Ghirardi - 2008 - Stanford Encyclopedia of Philosophy.
    Quantum mechanics, with its revolutionary implications, has posed innumerable problems to philosophers of science. In particular, it has suggested reconsidering basic concepts such as the existence of a world that is, at least to some extent, independent of the observer, the possibility of getting reliable and objective knowledge about it, and the possibility of taking (under appropriate circumstances) certain properties to be objectively possessed by physical systems. It has also raised many others questions which are well known to those involved (...)

    Position Measurement-Induced Collapse: A Unified Quantum Description of Fraunhofer and Fresnel Diffractions.Moncy V. John & Kiran Mathew - 2019 - Foundations of Physics 49 (4):317-329.
    Position measurement-induced collapse states are shown to provide a unified quantum description of diffraction of particles passing through a single slit. These states, which we here call ‘quantum location states’, are represented by the conventional rectangular wave function at the initial time of position measurement. We expand this state in terms of the position eigenstates, which in turn can be represented as a linear combination of energy eigenfunctions of the problem, using the closure property. The time-evolution of the location (...)

  8. Collapsing Emergence.Elanor Taylor - 2015 - Philosophical Quarterly 65 (261):732-753.
    The thesis that nature is composed of metaphysical levels is commonly understood in terms of emergence. In this paper, I uncover a problem for accounts of emergence, the collapse problem. The collapse problem suggests that emergence merely tracks relations between arbitrary groups of properties and so cannot be used in service of the levels view. I reject several failed attempts to solve the collapse problem and argue for an alternative solution according to which emergence is not (...)

    Gravitational Collapse in Quantum Einstein Gravity.Alfio Bonanno, Benjamin Koch & Alessia Platania - 2018 - Foundations of Physics 48 (10):1393-1406.
    The existence of spacetime singularities is one of the biggest problems of nowadays physics. According to Penrose, each physical singularity should be covered by a “cosmic censor” which prevents any external observer from perceiving their existence. However, classical models describing the gravitational collapse usually results in strong curvature singularities, which can also remain “naked” for a finite amount of advanced time. This proceedings studies the modifications induced by asymptotically safe gravity on the gravitational collapse of generic Vaidya spacetimes. It will (...)

  10. Theism and Modal Collapse.Klaas J. Kraay - 2011 - American Philosophical Quarterly 48 (4):361.
    God is traditionally taken to be a necessarily existing being who is unsurpassably powerful, knowledgeable, and good. The familiar problem of actual evil claims that the presence of gratuitous suffering in the actual world constitutes evidence against the existence of such a being. In contrast, the problem of possible evil claims that the possibility of bad worlds constitutes evidence against theism. How? It seems plausible to suppose that there are very bad possible worlds. But if God exists in (...)

    (1 other version)Does gravity induce wavefunction collapse? An examination of Penrose's conjecture.Shan Gao - 2013 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 44 (2):148-151.
    According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g. a quantum superposition of two different space–time geometries will collapse to one of them due to the ill-definedness of the time-translation operator for the superposition. In this paper, we argue that Penrose's conjecture on gravity's role in wavefunction collapse is debatable. First of all, it is still a controversial issue what the (...)

  12. Interpreting spontaneous collapse theories.Peter J. Lewis - 2004 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 36 (1):165-180.
    Spontaneous collapse theories of quantum mechanics require an interpretation if their claim to solve the measurement problem is to be vindicated. The most straightforward interpretation rule, the fuzzy link, generates a violation of common sense known as the counting anomaly. Recently, a consensus has developed that the mass density link provides an appropriate interpretation of spontaneous collapse theories that avoids the counting anomaly. In this paper, I argue that the mass density link violates common sense in just as striking (...)

    According to a particular interpretation of quantum mechanics, the causal role of human consciousness in the measuring process is called upon to solve a foundational problem called the “measurement problem.” Traditionally, this interpretation is tied up with the metaphysics of substance dualism. As such, this interpretation of quantum mechanics inherits the dualist’s mind-body problem. Our working hypothesis is that a process-based approach to the consciousness causes collapse interpretation (CCCI) ---leaning on Whitehead’s solution to the mind-body problem--- (...)

    Excuse, justification and collapse.Alexander Sarch - forthcoming - Jurisprudence.
    For any putative excuse, why not recast it as a justification rendering one’s wrongful conduct ultimately permissible? This paper confronts the worry that many, perhaps all, excuses might collapse into justifications – either in morality or criminal law. It is an especially pressing problem for normative expectations views, on which excuses speak to a lower standard than justifications. I argue that the prospects for decisively blocking collapse within morality look bleak – at least if we adhere to an important (...)

  15. Does Consciousness-Collapse Quantum Mechanics Facilitate Dualistic Mental Causation?Alin C. Cucu - forthcoming - Journal of Cognitive Science.
    One of the most serious challenges (if not the most serious challenge) for interactive psycho-physical dualism (henceforth interactive dualism or ID) is the so-called ‘interaction problem’. It has two facets, one of which this article focuses on, namely the apparent tension between interactions of non-physical minds in the physical world and physical laws of nature. One family of approaches to alleviate or even dissolve this tension is based on a collapse solution (‘consciousness collapse/CC) of the measurement problem in (...)

    Peter Lewis ([1997]) has recently argued that the wavefunction collapse theory of GRW (Ghirardi, Rimini and Weber [1986]) can only solve the problem of wavefunction tails at the expense of predicting that arithmetic does not apply to ordinary macroscopic objects. More specifically, Lewis argues that the GRW theory must violate the enumeration principle: that 'if marble 1 is in the box and marble 2 is in the box and so on through marble n, then all n marbles are in (...)

    Classical theism is often said to suffer from the problem of modal collapse: if God is necessary and simple then all of his effects (creatures) are also necessary. Many classical theists have turned to extrinsic predication in response: God’s simple and necessary act is compatible with any number of possible effects or no effects, and is only said to be an act of creating in virtue of the existence of the universe itself. Leftow and Schmid criticize this solution for (...)

  21. Simulation à la Goldman: pretend and collapse.Josef Perner & Johannes L. Brandl - 2009 - Philosophical Studies 144 (3):435-446.
    Theories of mind draw on processes that represent mental states and their computational connections; simulation, in addition, draws on processes that replicate (Heal 1986 ) a sequence of mental states. Moreover, mental simulation can be triggered by input from imagination instead of real perceptions. To avoid confusion between mental states concerning reality and those created in simulation, imagined contents must be quarantined. Goldman bypasses this problem by giving pretend states a special role to play in simulation (Goldman 2006 ). (...)

    Theistic modal realism and causal modal collapse.Nuno Maia - 2021 - Religious Studies 57 (1):120-135.
    Theistic modal realism argues for an extension of Lewis's modal realism capable of accommodating a theistic God. By affording elegant solutions to many atheistic challenges, the view is of great theoretical utility for the theist. However, it has been objected that within a Lewisian framework God cannot be causally efficacious on pain of collapsing intuitively distinct modal notions. In this article I explain why these worries are ill-founded and show how God's existence and causal power over the pluriverse can (...)

    Is Superluminal Signaling Possible in Collapse Theories of Quantum Mechanics?Shan Gao - 2023 - Foundations of Physics 53 (5):1-6.
    It is a received view that superluminal signaling is prohibited in collapse theories of quantum mechanics. In this paper, I argue that this may be not the case. I propose two possible mechanisms of superluminal signaling in collapse theories. The first one is based on the well-accepted solution to the tails problem, and the second one is based on certain assumptions about the minds of observers. Finally, I also discuss how collapse theories can avoid such superluminal signaling.

    A Proposal for a New Kind of Spontaneous Collapse Model.Nicolò Piccione - 2023 - Foundations of Physics 54 (1):1-24.
    Spontaneous collapse models are modifications of standard quantum mechanics in which a physical mechanism is responsible for the collapse of the wavefunction, thus providing a way to solve the so-called “measurement problem”. The two most famous of these models are the Ghirardi–Rimini–Weber (GRW) model and the Continuous Spontaneous Localisation (CSL) models. Here, we propose a new kind of non-relativistic spontaneous collapse model based on the idea of collapse points situated at fixed spacetime coordinates. This model shares properties of both (...)

    This paper examines three meta-ontological deflationary approaches – frameworks, verbal disputes, and metalinguistic negotiation – and applies them to ontological debates in philosophy of mind. An intriguing consequence of this application is that it reveals a deep, systematic problem for mental deflationism – specifically, a problem of cognitive collapse. This is surprising; cognitive collapse problems are usually reserved for serious ontological views such as eliminative materialism and mental fictionalism, not deflationism. This paper investigates why deflationism about the mental (...)

    A familiar interpretation of quantum mechanics (one of a number of views sometimes labeled the "Copenhagen interpretation'"), takes its empirical apparatus at face value, holding that the quantum wave function evolves by the Schrödinger equation except on certain occasions of measurement, when it collapses into a new state according to the Born rule. This interpretation is widely rejected, primarily because it faces the measurement problem: "measurement" is too imprecise for use in a fundamental physical theory. We argue that this (...)

    Crete in the Early Iron Age and Archaic periods presents a number of very particular problems for the ancient historian. Most educated lay people associate Crete with its Bronze Age civilization, the so-called Minoans, and most historians of ancient Greece tend to be more familiar with Athens and the Peloponnese. That is, after all, where the great events that Herodotus and Thucydides describe took place. Most of our literary sources for ancient Crete take the form of philosophical reflections or antiquarian (...)

    Emergent Causal Laws and Physical Laws.Ranpal Dosanjh - 2020 - Canadian Journal of Philosophy 50 (5):622-635.
    Contrasting accounts of physicalism and strong emergentism face two problems. According to the neutrality problem, contrasting supervenience-based formulations of these positions cannot be neutral with respect to certain unrelated metaphysical commitments. According to the collapse problem, emergent properties can be accounted for using an appropriately expansive physical ontology, rendering strong emergentism metaphysically suspect. I argue that both these problems can be solved with a principled distinction between emergent causal laws and physical laws. I propose such a distinction based (...)

    Collapse of a quantum field may affect brain function.C. M. H. Nunn, Christopher J. S. Clarke & B. H. Blott - 1994 - Journal of Consciousness Studies 1 (1):127-39.
    Experiments are described, using electroencephalography (EEG) and simple tests of performance, which support the hypothesis that collapse of a quantum field is of importance to the functioning of the brain. The theoretical basis of our experiments is derived from Penrose (1989) who suggested that conscious decision-making is a manifestation of the outcome of quantum computation in the brain involving collapse of some relevant wave function. He also proposed that collapse of any wave function depends on a gravitational criterion. As different (...)

These principles describe inconsistent behavior for quantum systems in so-called "measurement contexts." Many theorists have thought that the measurement problem can only be resolved by proposing a mechanistic explanation of (genuine or apparent) wavefunction collapse that avoids explicit reference to "measurement." However, I argue here that the measurement problem dissolves if we accept Humeanism about (...)

    Are Collapse Models Testable via Flavor Oscillations?Sandro Donadi, Angelo Bassi, Catalina Curceanu, Antonio Di Domenico & Beatrix C. Hiesmayr - 2013 - Foundations of Physics 43 (7):813-844.
    Collapse models predict the spontaneous collapse of the wave function, in order to avoid the emergence of macroscopic superpositions. In their mass-dependent formulation, they claim that the collapse of any system’s wave function depends on its mass. Neutral K, D, B mesons are oscillating systems that are given by Nature as superposition of two distinct mass eigenstates. Thus they are unique laboratory for testing collapse models that are sensitive to the mass. In this paper we derive—for the single mesons and (...)

Further, we aim to show that modal collapse properly fits into Gödel’s philosophical views, especially into his ontology of separation and union of force and fact, as well as into his cosmological theory of the nonobjectivity of the lapse of time.

    There have been many attempts to undertand the connections between quantum theory and Whiteheadian process philosophy. However, due to the ontological considerations, it is very important to specify which interpretation of quantum theory one embraces before inquiring into the details of Whitehead`s philosophy of organism. In this article, I argue that Ghirardi-Rimini-Weber (GRW) collapse interpretation of quantum theory serves as a suitable point of departure for future endeavors. Comparisons with many-worlds interpretation and decoherence approach have also been provided.

    Integrated Information-Induced Quantum Collapse.Kobi Kremnizer & André Ranchin - 2015 - Foundations of Physics 45 (8):889-899.
    We present a novel spontaneous collapse model where size is no longer the property of a physical system which determines its rate of collapse. Instead, we argue that the rate of spontaneous localization should depend on a system’s quantum Integrated Information, a novel physical property which describes a system’s capacity to act like a quantum observer. We introduce quantum Integrated Information, present our QII collapse model and briefly explain how it may be experimentally tested against quantum theory.

    Despite growing interest in risks of societal collapse due to anthropogenic climate change, there exists no consensus about how collapse should be understood. In this article, we critically examine existing definitions and argue that none adequately address the challenges for conceptualizing collapse that climate change presents. We therefore propose an alternative conception, which regards collapse as a reduction of collective capacity resulting in a pervasive and difficult-to-reverse loss of basic functionality. Our conception is dynamic in that it focuses on the (...)

    We define what it means for a function on ω1 to be a collapsing function for λ and show that if there exists a collapsing function for +, then there is no precipitous ideal on ω1. We show that a collapsing function for ω2 can be added by forcing. We define what it means to be a weakly ω1-Erdös cardinal and show that in L[E], there is a collapsing function for λ iff λ is less than (...)

    What collapse, exactly?Joseph Agassi - 2007 - Philosophy of the Social Sciences 37 (1):74-84.
    Hilary Putnam makes two related points in his recent collection of essays: (1) Values can be rational, and their inescapable intrusion into every kind of discourse is welcome. (2) Ignoring or suppressing this fact is common yet irrational. This is of course true; yet the intrusion in question can be trivial, and it can be problematic. Putnam ignores this here. The book is pleasant to read; it is infused with friendly and appreciative personal anecdotes and observations. It is almost entirely (...)

    Do Modal Distinctions Collapse in Carnap’s System?Genoveva Marti - 1994 - Journal of Philosophical Logic 23 (6):575 - 593.
    Føllesdal (1966 and 1969) claims that modal distinctions collapse, that is that p and Necessarily p are equivalent, in any system of modal logic that incorporates a standard theory of definite descriptions, like the one proposed by Carnap in M&N. I argue that his argument fails.

  47. Collapse Models:a theoretical, experimental and philosophical review.Mauro Dorato, Angelo Bassi & Hendrik Ulbricht - 2023 - Entropy 25 (645):1.
    In this paper, we review and connect the three essential conditions needed by the collapse model to achieve a complete and exact formulation, namely the theoretical, the experimental, and the ontological ones. These features correspond to the three parts of the paper. In any empirical science, the first two features are obviously connected but, as is well known, among the different formulations and interpretations of non-relativistic quantum mechanics, only collapse models, as the paper well illustrates with a richness of details, (...)

    Collapse theories as beable theories.Guido Bacciagaluppi - 2010 - Manuscrito 33 (1):19-54.
    I discuss the interpretation of spontaneous collapse theories, with particular reference to Bell's suggestion that the stochastic jumps in the evolution of the wave function should be considered as local beables of the theory. I develop this analogy in some detail for the case of non-relativistic GRW-type theories, using a generalisation of Bell's notion of beables to POV measures. In the context of CSL-type theories, this strategy appears to fail, and I discuss instead Ghirardi and co-workers' mass-density interpretation and its (...)

  49. Quantum collapse, consciousness and superluminal communication.Shan Gao - 2004 - Foundations Of Physics Letters 17 (2):167-182.
    The relation between quantum collapse, consciousness and superluminal communication is analyzed. As we know, quantum collapse, if exists, can result in the appearance of quantum nonlocality, and requires the existence of a pre- ferred Lorentz frame. This may permit the realization of quantum superluminal communication (QSC), which will no longer result in the usual causal loop in case of the existence of a preferred Lorentz frame. The possibility of the existence of QSC is further analyzed under the assumption that quantum (...)

    Predicative collapsing principles.Anton Freund - 2020 - Journal of Symbolic Logic 85 (1):511-530.
    We show that arithmetical transfinite recursion is equivalent to a suitable formalization of the following: For every ordinal \alpha there exists an ordinal /beta such that 1 + \beta \cdot (\beta + \alpha) admits an almost order preserving collapse into \beta. Arithmetical comprehension is equivalent to a statement of the same form, with \beta \cdot \alpha at the place of \beta \cdot (\beta + \alpha). We will also characterise the principles that any set is contained in a countable coded ω-model (...)
