  1. Probabilism for stochastic theories.Jer Steeger - 2019 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 66:34–44.
    I defend an analog of probabilism that characterizes rationally coherent estimates for chances. Specifically, I demonstrate the following accuracy-dominance result for stochastic theories in the C*-algebraic framework: supposing an assignment of chance values is possible if and only if it is given by a pure state on a given algebra, your estimates for chances avoid accuracy-dominance if and only if they are given by a state on that algebra. When your estimates avoid accuracy-dominance (roughly: when you cannot guarantee that other (...)

  2. One world is (probably) just as good as many.Jer Steeger - 2022 - Synthese 200 (97):1-32.
    One of our most sophisticated accounts of objective chance in quantum mechanics involves the Deutsch-Wallace theorem, which uses state-space symmetries to justify agents’ use of the Born rule when the quantum state is known. But Wallace argues that this theorem requires an Everettian approach to measurement. I find that this argument is unsound. I demonstrate a counter-example by applying the Deutsch-Wallace theorem to the de Broglie-Bohm pilot-wave theory.

  3. Is the classical limit “singular”?Jer Steeger & Benjamin H. Feintzeig - 2021 - Studies in History and Philosophy of Science Part A 88 (C):263-279.
    We argue against claims that the classical ℏ → 0 limit is “singular” in a way that frustrates an eliminative reduction of classical to quantum physics. We show one precise sense in which quantum mechanics and scaling behavior can be used to recover classical mechanics exactly, without making prior reference to the classical theory. To do so, we use the tools of strict deformation quantization, which provides a rigorous way to capture the ℏ → 0 limit. We then use the (...)

  4. Hypothetical Frequencies as Approximations.Jer Steeger - 2024 - Erkenntnis 89 (4):1295-1325.
    Hájek (Erkenntnis 70(2):211–235, 2009) argues that probabilities cannot be the limits of relative frequencies in counterfactual infinite sequences. I argue for a different understanding of these limits, drawing on Norton’s (Philos Sci 79(2):207–232, 2012) distinction between approximations (inexact descriptions of a target) and idealizations (separate models that bear analogies to the target). Then, I adapt Hájek’s arguments to this new context. These arguments provide excellent reasons not to use hypothetical frequencies as idealizations, but no reason not to use them as (...)

  5. Extensions of bundles of C*-algebras.Jer Steeger & Benjamin Feintzeig - 2021 - Reviews in Mathematical Physics 33 (8):2150025.
    Bundles of C*-algebras can be used to represent limits of physical theories whose algebraic structure depends on the value of a parameter. The primary example is the ℏ→0 limit of the C*-algebras of physical quantities in quantum theories, represented in the framework of strict deformation quantization. In this paper, we understand such limiting procedures in terms of the extension of a bundle of C*-algebras to some limiting value of a parameter. We prove existence and uniqueness results for such extensions. Moreover, (...)

  6. Two Forms of Inconsistency in Quantum Foundations.Jer Steeger & Nicholas Teh - 2021 - British Journal for the Philosophy of Science 72 (4):1083-1110.
    Recently, there has been some discussion of how Dutch Book arguments might be used to demonstrate the rational incoherence of certain hidden variable models of quantum theory. In this paper, we argue that the 'form of inconsistency' underlying this alleged irrationality is deeply and comprehensively related to the more familiar 'inconsistency' phenomenon of contextuality. Our main result is that the hierarchy of contextuality due to Abramsky and Brandenburger corresponds to a hierarchy of additivity/convexity-violations which yields formal Dutch Books of different (...)

  7. Optøjer som demokratisk ret.Philip Højme - 2021 - Antifacistisk Forum 1 (1):34-41.
    Lately, there has been a lot of talk about the Ghettos, about wayward youths and Instagram rappers that glorify violence. In this piece, a Warsaw-based philosopher contributes to this discussion by examining the music of the ghetto and the culture of riots. Not in opposition to how bourgeois society usually frames such acts of discontent but rather as a reasonable democratic right that minorities are entitled to.

    Je li Matija Vlačić Ilirik zagovornik hermeneutičkog realizma?Jure Zovko & Maja Ferenec Kuća - 2022 - Prilozi Za Istrazivanje Hrvatske Filozofske Baštine 48 (1):151-174.
    Ugledni mislitelji hermeneutičke filozofije Wilhelm Dilthey i Hans-Georg Gadamer okarakterizirali su Matiju Vlačića Ilirika kao klasika hermeneutičkog pristupa filozofiji. Taj sud dodatno dobiva na snazi jer su Dilthey i Gadamer okarakterizirani kao pristaše relativističke hermeneutike, dok je Vlačić inzistirao na adekvatnom razumijevanju i interpretiranju teksta. Uzevši u obzir da je za Vlačića ključno pravilo bilo da tekst treba tumačiti sukladno njegovu imanentnom smislu, razradio je dvije interpretacijske maksime, skop i hermeneutički krug, presudne za daljnji razvoj i konstituiranje hermeneutike kao metode (...)

    Iz Platonove filozofije.Irina Deretić - 2010 - Beograd: Plato.
    Kako je moguće baviti se Platonom danas, ukoliko je filozofija „svoje vreme obuhvaćeno mislima“? Autor Platonovom delu ne pristupa kao dogmatskom štivu, već kao tekstu prožetom paradoksima, koje izmiče svakom unapred pripremljenom, šematizovanom modelu čitanja. Obratiti se Platonu kao filozofskoj paradigmi isplativo je ukoliko filozofi koji progovaraju iz dubine vremena mogu nešto važno da nam saopšte i ukoliko smo kadri da im postavimo autentično pitanje. Zato filozofi moraju imati dah delfskog ronioca, jer biser se ne nalazi u svakoj školjci. Knjiga (...)
