  2. The Internal Physical State View of Sensory Experience (chapter from my book *Perception*).Adam Pautz - forthcoming - In Perception.
    This is a chapter from my book Perception (Routledge). I explain the physical state view of sensory experience (Papineau, McLaughlin, others). I criticize an argument against it based on the "transparency observation". Then I develop two alternative arguments against it. The first is a Leibniz's Law argument based on the essentially externally directed character of some experiences. The second concerns "brains in vats". Finally I consider a recent response due to David Papineau, which involves rejecting essential external directedness.

  4. Do the Laws of Physics State the Facts?Nancy Cartwright - 1980 - Pacific Philosophical Quarterly 61 (1-2):75-84.
    The facticity view of fundamental laws of physics takes them to state facts about reality. To preserve the facticity of laws in the face of complex phenomena with multiple intervening factors, composition of causes, often by vector addition, is invoked. However, this addition should be read only as a metaphor, for only the resultant force is real. The truth and the explanatory power of laws can both be preserved by viewing laws as describing causal powers that objects possess, but this (...)

  6. Irreversibility, Statistical Mechanics and the Nature of Physical States.Robert W. Batterman - 1987 - Dissertation, University of Michigan
    I. Prigogine has proposed, and the writings of N. S. Krylov to some extent suggest, a novel and unorthodox solution to foundational problems in statistical mechanics. In particular, the view claims to offer new insight into two interconnected problems: understanding the role of probability in physics, and that of reconciling the irreversibility of physical processes with the temporal symmetry of dynamical theories. The approach in question advocates a conception of the state of a system which incorporates features of the (...)

    An Emerging Group of Membrane Property Sensors Controls the Physical State of Organellar Membranes to Maintain Their Identity.Toni Radanović, John Reinhard, Stephanie Ballweg, Kristina Pesek & Robert Ernst - 2018 - Bioessays 40 (5):1700250.
    The biological membranes of eukaryotic cells harbor sensitive surveillance systems to establish, sense, and maintain characteristic physicochemical properties that ultimately define organelle identity. They are fundamentally important for membrane homeostasis and play active roles in cellular signaling, protein sorting, and the formation of vesicular carriers. Here, we compare the molecular mechanisms of Mga2 and Ire1, two sensors involved in the regulation of fatty acid desaturation and the response to unfolded proteins and lipid bilayer stress in order to identify their commonalities (...)

    Symmetries and the identity of physical states.Simon Friederich - 2016 - EPSA15 Selected Papers 5.
    The paper proposes a combined account of identity for physical states and direct empirical significance for symmetries according to which symmetry-related state variables designate distinct physical states if and only if the symmetry that relates them has direct empirical significance. Strengthening an earlier result, I show that, given this combined account, the local gauge symmetries in our leading contemporary theories of particle physics do not have any direct empirical significance.

  9. Toppling the Pyramids: physics without physical state monism.William Simpson & Simon Horsley - 2022 - In Christopher J. Austin, Anna Marmodoro & Andrea Roselli (eds.), Powers, Time and Free Will. pp. 17–50.
    In this paper, we challenge a wide-spread assumption among philosophers that contemporary physics supports physical state monism. This is the claim that the causal powers of a system supervene upon the ‘lower-level’ laws and the lower-level state of the cosmos (as represented by our ‘best physics’). On this view, it makes sense to ignore a macroscopic system’s higher-level properties in determining its causal powers, since any higher-level powers are merely artifacts of our special interests. We argue that this assumption (...)

    Solid State Insurrection: How the Science of Substance Made American Physics Matter.Joseph D. Martin - 2018 - Pittsburgh, PA, USA: University of Pittsburgh Press.
    Solid state physics, the study of the physical properties of solid matter, was the most populous subfield of Cold War American physics. Despite prolific contributions to consumer and medical technology, such as the transistor and magnetic resonance imaging, it garnered less professional prestige and public attention than nuclear and particle physics. Solid State Insurrection argues that solid state physics was essential to securing the vast social, political, and financial capital Cold War physics enjoyed in the twentieth century. Solid state’s (...)

  12. Stating structural realism: mathematics‐first approaches to physics and metaphysics.David Wallace - 2022 - Philosophical Perspectives 36 (1):345-378.
    I respond to the frequent objection that structural realism fails to sharply state an alternative to the standard predicate-logic, object / property / relation, way of doing metaphysics. The approach I propose is based on what I call a ‘math-first’ approach to physical theories (close to the so-called ‘semantic view of theories') where the content of a physical theory is to be understood primarily in terms of its mathematical structure and the representational relations it bears to physical (...)

    Physical uniformities on the state space of nonrelativisitic quantum mechanics.Reinhard Werner - 1983 - Foundations of Physics 13 (8):859-881.
    Uniformities describing the distinguishability of states and of observables are discussed in the context of general statistical theories and are shown to be related to distinguished subspaces of continuous observables and states, respectively. The usual formalism of quantum mechanics contains no such physical uniformity for states. Using recently developed tools of quantum harmonic analysis, a natural one-to-one correspondence between continuous subspaces of nonrelativistic quantum and classical mechanics is established, thus exhibiting a close interrelation between physical (...)

    Children’s and young persons’ rights have received increasing been focus in recent decades, due in a significant degree to the UN Convention on the Rights of the Child. In Sweden, compulsory care in the social-services system is disputed, not least for the forceful measures that facility personnel have at their disposal to control children in certain conflict situations.

    Individual samples, preparations, and states in Piron's approach to quantum physics.Gianpiero Cattaneo, Tiziana Marsico & Giuseppe NisticÒ - 1994 - Foundations of Physics 24 (9):1293-1303.
    The mathematical description of the three distinct fundamental notions of “individual sample” of “preparing procedure,” and of “Piron's state” of a physical entity are precisely introduced in the framework of the Piron's “preparation-question structure” (without specific axioms C, P, A) based on Ludwig's “selection structure.” We compare our realization of the above notions with a similar use of the standard terminology of the “Geneva School” adopted by Pykacz and Santos in a recent paper.

  22. Relativistic Implications for Physical Copies of Conscious States.Andrew Knight - manuscript
    The possibility of algorithmic consciousness depends on the assumption that conscious states can be copied or repeated by sufficiently duplicating their underlying physical states, leading to a variety of paradoxes, including the problems of duplication, teleportation, simulation, self-location, the Boltzmann brain, and Wigner’s Friend. In an effort to further elucidate the physical nature of consciousness, I challenge these assumptions by analyzing the implications of special relativity on evolutions of identical copies of a mental state, particularly the (...)

    We show how effect algebras arise in physics and how they can be used to tie together the observables, states and symmetries employed in the study of physical systems. We introduce and study the unifying notion of an effect-observable-state-symmetry-system (EOSS-system) and give both classical and quantum-mechanical examples of EOSS-systems.

    Everettian quantum mechanics and physical probability: Against the principle of “State Supervenience”.Lina Jansson - 2016 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 53:45-53.
    Everettian quantum mechanics faces the challenge of how to make sense of probability and probabilistic reasoning in a setting where there is typically no unique outcome of measurements. Wallace has built on a proof by Deutsch to argue that a notion of probability can be recovered in the many worlds setting. In particular, Wallace argues that a rational agent has to assign probabilities in accordance with the Born rule. This argument relies on a rationality constraint that Wallace calls state supervenience. (...)

    Information Theoretic Characterization of Physical Theories with Projective State Space.Marco Zaopo - 2015 - Foundations of Physics 45 (8):943-958.
    Probabilistic theories are a natural framework to investigate the foundations of quantum theory and possible alternative or deeper theories. In a generic probabilistic theory, states of a physical system are represented as vectors of outcomes probabilities and state spaces are convex cones. In this picture the physics of a given theory is related to the geometric shape of the cone of states. In quantum theory, for instance, the shape of the cone of states corresponds to a (...)

    Emergence in Solid State Physics and Biology.George F. R. Ellis - 2020 - Foundations of Physics 50 (10):1098-1139.
    There has been much controversy over weak and strong emergence in physics and biology. As pointed out by Phil Anderson in many papers, the existence of broken symmetries is the key to emergence of properties in much of solid state physics. By carefully distinguishing between different types of symmetry breaking and tracing the relation between broken symmetries at micro and macro scales, I demonstrate that the emergence of the properties of semiconductors is a case of strong emergence. This is due (...)

    Comparing the long-term evolution of ``cognitive invariances'' in physics with a dynamics in states of consciousness.Gerhard Grössing - 2001 - Foundations of Science 6 (4):255-272.
    It is shown that the evolution of physics canin several regards be described by elements of``regression'', i.e., that within a certaintradition of ideas one begins with theconstruction of most ``plausible'' statements(axioms) at hand, and then ``works onselfbackwards'' with respect to developmental terms.As a consequence of this strategy, the furtherwork proceeds along such a ``regressive'' path,the more one arrives at concepts andrelationships which are unexpected or evencounter-intuitive in terms of our everydayexperiences. However, a comparable phenomenology is wellknown from studies on (...) of consciousness.In particular, the evolutionary logic of theconstructions of major ``cognitive invariances''in physics, which is in part due to everincreasing rates of data processing, ismirrored in a logic of states of consciousnesswhich deviate from a ``normal'' state of dailyroutine along increasing levels of centralnervous arousal. Examples are given from the evolution ofphysics, and future perspectives are brieflyoutlined on the basis thereof. (shrink)

    Leibniz’s Analysis of Change: Vague States, Physical Continuity, and the Calculus.Richard Arthur - unknown
    One of the most puzzling features of Leibniz’s deep metaphysics is the apparent contradiction between his claims that the law of continuity holds everywhere, so that in particular, change is continuous in every monad, and that “changes are not really continuous,” since successive states contradict one another. In this paper I try to show in what sense these claims can be understood as compatible. My analysis depends crucially on Leibniz’s idea that enduring states are “vague,” and abstract away (...)

    A complete theoretical model describing artificial disintegration of nuclei by bombardment with α-particles, developed by Majorana as early as 1930, is discussed in detail jointly with the basic experimental evidences that motivated it. By following the quantum dynamics of a state resulting from the superposition of a discrete state with a continuum one, whose interaction is described by a given potential term, Majorana obtained (among the other predictions) the explicit expression for the integrated cross section of the nuclear process, which (...)

    In Physical Realization, Sydney Shoemaker considers the question of how physicalism can be true: how can all facts about the world, including mental ones, be constituted by facts about the distribution in the world of physical properties? Physicalism requires that the mental properties of a person are 'realized in' the physical properties of that person, and that all instantiations of properties in macroscopic objects are realized in microphysical states of affairs. Shoemaker offers an account of both (...)

Hiesmayr, Florian Hipp, Marcus Huber, Gerd Krizek, Karoline Mühlbacher, Sasa Radic, Christoph Spengler & Lukas Theussl - 2012 - Foundations of Physics 42 (6):778-802.
    An effective formalism is developed to handle decaying two-state systems. Herewith, observables of such systems can be described by a single operator in the Heisenberg picture. This allows for using the usual framework in quantum information theory and, hence, to enlighten the quantum features of such systems compared to non-decaying systems. We apply it to systems in high energy physics, i.e. to oscillating meson–antimeson systems. In particular, we discuss the entropic Heisenberg uncertainty relation for observables measured at different times at (...)

This volume examines fundamental questions which connect scholars from both disciplines: is the universe a computer? Can a universal computing machine simulate every physical process? What is the source of the computational power of quantum computers? Are computational approaches to solving physical problems (...)
