    An Inferential Account on Theoretical Concepts in Physics.Javier Anta - 2021 - Critica 52 (156).
    In this paper we develop an inferential account on the meaning and reference of theoretical concepts in physics, mainly based on the pragmatic notion of ‘inferential validity’. Firstly, we distinguish between empirical meaningfulness and theoretical significance as two different modes of meaning, wherein the former depends on consistently encoding experimental values, as proposed by Chang, and the latter on being semantically coherent with other concepts. Secondly, we argue that each of these contributions to the validity of inferences imports a causal (...)

  2. A Philosopher Against the Bandwagon. Carnap and the Informationalization of Thermal Physics.Javier Anta - forthcoming - Hopos: The Journal of the International Society for the History of Philosophy of Science.
    In this paper I aim to demonstrate that Rudolf Carnap's analysis of the application of information theory within physics, an intellectual-historical precedent of current philosophical criticisms toward this tendency, is justified. First, Carnap and Bar-Hillel (1952) underlined the unjustified ‘semantification’ of Shannon entropy Furthermore, Carnap criticized the ‘physicalization’ of Shannon entropy, but that criticism was not accepted by the physics community of the 1950s (Köhler 2001). Finally, in the posthumously published "Two Essays on Entropy" Carnap (1977) developed a critical assessment (...)

    Can Informational Thermal Physics Explain the Approach to Equilibrium?Javier Anta - 2021 - Synthese 199 (1-2):4015–4038.
    In this paper I will defend the incapacity of the informational frameworks in thermal physics, mainly those that historically and conceptually derive from the work of Brillouin (1962) and Jaynes (1957a), to robustly explain the approach of certain gaseous systems to their state of thermal equilibrium from the dynamics of their molecular components. I will further argue that, since their various interpretative, conceptual and technical-formal resources (e.g. epistemic interpretations of probabilities and entropy measures, identification of thermal entropy as Shannon information, (...)

    Diagrams as Part of Physical Theories: A Representational Conception.Javier Anta - 2021 - In 12th International Conference, Diagrams 2021, Virtual, September 28–30, 2021, Proceedings. pp. 52-59.
    Throughout the history of the philosophy of science, theories have been linked to formulas as a privileged representational format. In this paper, following, I defend a semantic-representational conception of theories, where theories are identified with sets of scientific re-presentations by virtue of their epistemic potential and independently of their format. To show the potential of this proposal, I analyze as a case study the use of phase diagrams in statistical mechanics to convey in a semantically consistent and syntactically correct way (...)

    Explicaciones Geométrico-Diagramáticas en Física desde una Perspectiva Inferencial.Javier Anta - 2019 - Revista Colombiana de Filosofía de la Ciencia 38 (19).
    El primer objetivo de este artículo es mostrar que explicaciones genuinamente geométricas/matemáticas e intrínsecamente diagramáticas de fenómenos físicos no solo son posibles en la práctica científica, sino que además comportan un potencial epistémico que sus contrapartes simbólico-verbales carecen. Como ejemplo representativo utilizaremos la metodología geométrica de John Wheeler (1963) para calcular cantidades físicas en una reacción nuclear. Como segundo objetivo pretendemos analizar, desde un marco inferencial, la garantía epistémica de este tipo de explicaciones en términos de dependencia sintáctica y semántica (...)

  7. Framing the Epistemic Schism of Statistical Mechanics.Javier Anta - 2021 - Proceedings of the X Conference of the Spanish Society of Logic, Methodology and Philosophy of Science.
    In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...)

    Indispensability and Effectiveness of Diagrams in Molecular Biology.Javier Anta - 2019 - Quaderns de Filosofia 6 (1):29-46.
    In this paper I aim to defend a twofold thesis. On one hand, I will sup-port, against Perini [7], the indispensability of diagrams when structurally complex biomolecules are concerned, since it is not possible to satisfactorily use linguistic-sentential representations at that domain. On the other hand, even when diagrams are dispensable I will defend than they will generally be more effective than other representations in encoding biomolecular knowledge, relying on Kulvicki-Shimojima’s diagrammatic effectiveness thesis. Finally, I will ground many epistemic virtues (...)

    Integrating Inferentialism About Physical Theories and Representations: A Case for Phase Diagrams.Javier Anta - 2021 - Critica 53 (158):47–77.
    In this paper we argue for an integrated inferential conception about theories and representations and its role in accounting for the theoretical value of philosophically disregarded representational practices, such as the systematic use of phase space diagrams within the theoretical context of statistical mechanics. This proposal would rely on both inferentialism about scientific representations (Suárez 2004) and inferentialism about particular physical theories (Wallace 2017). We defend that both perspectives somehow converge into an integrated inferentialism by means of the thesis theories (...)

    Ignorance, Milk and Coffee: Can Epistemic States Be Causally-Explanatorily Relevant in Statistical Mechanics?Javier Anta - 2021 - Foundation of Science.
    In this paper I will evaluate whether some knowledge states that are interpretatively derived from statistical mechanical probabilities could be somehow relevant in actual practices, as famously rejected by Albert (2000). On one side, I follow Frigg (2010a) in rejecting the causal relevance of knowledge states as a mere byproduct of misinterpreting this theoretical field. On the other side, I will argue against Uffink (2011) that probability-represented epistemic states cannot be explanatorily relevant, because (i) probabilities cannot faithfully represent significant epistemic (...)

  11. Information, Meaning and Physics: The Intellectual Transformation of the English School of Information Theory During 1946-1956.Javier Anta - forthcoming - Science in Context.
    In this comparative historical analysis, we will analyze the intellectual tendency that emerged between 1946 and 1956 to take advantage of the popularity of communication theory to develop a kind of informational epistemology of statistical mechanics. We will argue that this tendency results from a historical confluence in the early 1950s of certain theoretical claims of the so-called English School of Information Theory, championed by authors such as Gabor (1956) or MacKay (1969), and the search to extend the profound success (...)

    Make Information in Science Meaningful Again.Javier Anta - 2021 - Logos and Episteme: An International Journal of Epistemology (3):263-286.
    Although the everyday notion of information has clear semantic properties, the all-pervasive technical concept of Shannon information is usually considered as a non-semantic concept. In this paper I show how this concept was implicitly ‘semantized’ in the early 1950s by many authors, such as Rothstein or Brillouin, in order to explain the knowledge dynamics underlying certain scientific practices such as measurement. On the other hand, I argue that the main attempts in the literature to develop a quantitative measure of semantic (...)

    En este artículo pretendo evaluar las bases conceptuales y interpretativas de las ‘paradojas info-térmicas’ subyacentes a las aproximaciones informacionales a la física térmica, por las cuales nuestra información epistémica sobre un sistema molecular aumenta y disminuye simultáneamente cuando este se aproxima al equilibrio térmico. Defiendo que el contenido paradójico de nuestra tesis persiste incluso cuando se distinguen distintos tipos de información, debido a la conexión robusta entre la parte del incremento y la parte de la disminución informacional de la tesis.

  14. Sympathy for the Demon. Rethinking Maxwell’s Thought Experiment in a Maxwellian Vein.Javier Anta - 2021 - Teorema: International Journal of Philosophy 40 (3):49-64.
    In this paper I will defend an approach to the thought experiment known as ‘Maxwell’s Demon’ based on a Maxwellian conception of statistical mechanics. Instead of assuming that thermodynamic descriptions depend reductively on the dynamics of molecular components, I will adopt a conception of thermophysics as a ‘resource theory’ in the Maxwellian line recently defended by Myrvold (2011) and Wallace (2017). From this interpretative stance, Maxwell’s demon would not lead directly to the plausibility of violating the second law of thermodynamics, (...)

    In this study I aim to develop a cognitive evaluation of how semantically-driven and rule-based diagrammatic reasoning were psychologically plausible for partic-ular cases of scientific practice: an actual trackless path reconstruction in bubble chamber experiments, as reported by Galison (1997). I will propose “cognitive imagery projection and manipulation” (CIPM) as the most plausible psychologi-cal (perceptual/attentional/cognitive) mechanism matching the specific explanatory requirements for the case study, outlining the most significant current theories about this mental phenomenon (Shimojima; 2011).

    The Epistemic Schism of Statistical Mechanics.Javier Anta - 2021 - Theoria 36 (3):399-419.
    In this paper I will argue that the two main approaches to statistical mechanics, that of Boltzmann and Gibbs, constitute two substantially different theoretical apparatuses. Particularly, I defend that this theoretical split must be philosophically understood as a separation of epistemic functions within this physical domain: while Boltzmannians are able to generate powerful explanations of thermal phenomena from molecular dynamics, Gibbsians can statistically predict observable values in a highly effective way. Therefore, statistical mechanics is a counterexample to Hempel's (1958) symmetry (...)

    Un mundo de estructuras: Simetrías Grupo-Teóricas desde el Realismo Infoestructural.Javier Anta - 2019 - Metatheoria 10 (1):1-11.
    Ontic Structural Realism, as pivotal position in philosophy of science and metaphysics, defends the idea that the world is ultimately constituted of real physical structures. French (2014) regards physical symmetries as the foundational structure of a world without objects. On the other hand, Ladyman and Ross (2007) hold that the world is essentially made of non-redundant informational structure. I argue in this paper that these two positions are by no means incompatible, for instance by interpreting French’s physical symmetries as real (...)
