    Are Metaphysical Claims Testable?Chrysovalantis Stergiou - forthcoming - Philosophia:1-18.
    To consider metaphysical claims a priori and devoid of empirical content, is a rather commonplace received opinion. This paper attempts an exploration of a contemporary philosophical heresy: it is possible to test metaphysical claims if they play an indispensable role in producing empirical success, i.e. novel predictions. To do so one, firstly, needs to express the metaphysical claims employed in the logico-mathematical language of a scientific theory, i.e. to explicate them. Secondly, they should have an understanding of what it is (...)

    Explaining Correlations by Partitions.Chrysovalantis Stergiou - 2015 - Foundations of Physics 45 (12):1599-1612.
    In this paper two accounts of Reichenbachian common cause systems are compared. Examples are provided which show that Hofer-Szabó and Rédei account and Hofer-Szabó et al. account is compatible, with but not equivalent, to Mazzola’s. Moreover, the difference of the two accounts with respect to their explanatory adequacy is discussed, in the light of Salmon’s statistical-relevance approach to statistical explanation.

    On Particle Phenomenology Without Particle Ontology: How Much Local Is Almost Local?Aristidis Arageorgis & Chrysovalantis Stergiou - 2013 - Foundations of Physics 43 (8):969-977.
    Recently, Clifton and Halvorson have tried to salvage a particle phenomenology in the absence of particle ontology within algebraic relativistic quantum field theory. Their idea is that the detection of a particle is the measurement of a local observable which simulates the measurement of an almost local observable that annihilates the vacuum. In this note, we argue that the measurements local particle detections are supposed to simulate probe radically holistic aspects of relativistic quantum fields. We prove that in an axiomatic (...)

    Empirical Underdetermination for Physical Theories in C* Algebraic Setting: Comments to an Arageorgis's Argument.Chrysovalantis Stergiou - 2020 - Foundations of Physics 50 (9):877-892.
    In this paper, I reconstruct an argument of Aristidis Arageorgis against empirical underdetermination of the state of a physical system in a C*-algebraic setting and explore its soundness. The argument, aiming against algebraic imperialism, the operationalist attitude which characterized the first steps of Algebraic Quantum Field Theory, is based on two topological properties of the state space: being T1 and being first countable in the weak*-topology. The first property is possessed trivially by the state space while the latter is highly (...)

    Common Causes Love to Hide: Gábor Hofer-Szabó, Miklós Rédei and László E. Szabó: The Principle of the Common Cause. Cambridge: Cambridge University Press, 2013, Vii+202pp, $99.00 HB. [REVIEW]Chrysovalantis Stergiou - 2015 - Metascience 24 (2):247-251.
    Anything other than paraphrasing the well-known Heraclitean aphorism would not be more appropriate to portray the crux of the contribution of the three philosophers of the Budapest School, Gábor Hofer-Szabó, Miklós Rédei and Lázló E. Szabó, in the ongoing discussion of the principle of the common cause . Indeed, ‘common causes love to hide’ and for that reason critics and aspirant falsifiers of PCC find correlations which, at a first level of analysis, might lack a common cause explanation. But as (...)

    Two Comments on the Common Cause Principle in Algebraic Quantum Field Theory.Chrysovalantis Stergiou - 2009 - In Henk W. de Regt (ed.), Epsa Philosophy of Science: Amsterdam 2009. Springer. pp. 387--402.
    I present two relatively independent sets of remarks on common causes and the violation of Bell inequalities in algebraic quantum field theory. The first set of remarks concerns the possibility of reconciling Reichenbachian ideas on common causes with quantum field theory in the face of an already known difficulty: the event shown to satisfy statistical relations for being the common cause of two correlated events has been associated with the union, rather than the intersection, of the backward light cones of (...)

    Book Notice: Bernard D’Espagnat: On Physics and Philosophy. Princeton and Oxford: Princeton University Press, 2013, Xiv+503pp, $27.95 PB. [REVIEW]Chrysovalantis Stergiou - 2014 - Metascience 23 (3):489-490.
    In 2013, we welcomed the paperback edition of this voluminous work, authored by Bernard d’Espagnat—a theoretical physicist having a special interest in philosophy and, particularly, in the investigation of the conceptual foundations of physics, dated from the mid 60s. The book tries to articulate a view on realism, open realism, abiding it by the developments in the twentieth-century physics.The work consists of two parts. In the first one, the author undertakes a negative task: to question what he calls objectivist realism (...)

    Note on Simplicity and Statistical Explanations of Correlations.Chrysovalantis Stergiou - unknown
    In this note, I discuss the simplicity of rival statistical explanations of a correlation, couched in terms of Reichenbachian Common Cause Systems. Simplicity is analyzed in two components, the so-called intrinsic and contextual simplicity. I show that if one disentangles simplicity from explanatory power then the size of the system provides an adequate for simplicity in both of its dimensions.

    Causal Processes and Locality in Classical and in Quantum Physics.Chrysovalantis Stergiou - 2011 - Dissertation, University of Athens & National Technical University of Athems
    In this work we try to study theories of causation based upon causal processes and causal interactions in the context of classical and quantum physics. Our central aim is to find out whether such causal theories are compatible with the world picture suggested by contemporary theories of physics. In the first part, we review, compare and try to place among more general taxonomical schemes, the causal theories by Russell (the causal lines approach), Reichenbach (mark method, probabilistic causality and the principle (...)
