    Discussions on physics, metaphysics and metametaphysics: Interpreting quantum mechanics

    This thesis inquires what it means to interpret non-relativistic quantum mechanics (QM), and the philosophical limits of this interpretation. In pursuit of a scientific-realist stance, a metametaphysical method is expanded and applied to evaluate rival interpretations of QM, based on the conceptual distinction between ontology and metaphysics, for objective theory choice in metaphysical discussions relating to QM. Three cases are examined, in which this metametaphysical method succeeds in indicating what are the wrong alternatives to interpret QM in metaphysical terms. The first two cases failed in doing so due to different kinds of underdetermination. In the third case, unlike underdetermination, where there are many choices to be made, a “null-determination” is proposed where there may be no metaphysical choices in the available metaphysical literature. Considering what has been discussed, an agnostic philosophic position is adopted concerning the possibility of interpreting QM from a scientific-realistic point of view

    Nomic realism, simplicity, and the simplicity bubble effect

    We offer an argument against simplicity as a sole intrinsic criterion for nomic realism. The argument is based on the simplicity bubble effect. Underdetermination in quantum foundations illustrates the case.Comment: Contributed talk for the Third Graduate Conference of the Italian Network for the Philosophy of Mathematics --- FilMat.

    This book deals with some ontological implications of standard non-relativistic quantum mechanics, and the use of the notion of `consciousness' to solve the measurement problem

    Felinos inseparáveis: considerações históricas e filosóficas acerca do problema da medição em mecânica quântica

    Get PDF
    Este artigo trata de aspectos abordados aspectos históricos e filosóficos do problema da medição em mecânica quântica, com ênfase na famosa formulação de Erwin Schrödinger conhecida como o “paradoxo do Gato de Schrödinger”. Pensado para o uso em sala de aula em cursos de filosofia da ciência a nível de graduação e pós-graduação, o artigo trata, em especial: da gênese do problema da medição (§ 1); sua conexão com os debates filosóficos sobre a localidade e separabilidade (§ 2); as consequências para debates futuros na metafísica da ciência (§ 3).   Palavras-chave: filosofia da mecânica quântica; gato de Schrödinger; metafísica da ciência; problema da medição; separabilidade. &nbsp

    Making New Tools From the Toolbox of Metaphysics

    In this review, I specify the metametaphysical background against which Alastair Wilson’s “The Nature of Contingency” (Oxford University Press, 2020) should be properly understood. Metaphysics, as a philosophical discipline, is standing on thin ice. The caricature of the situation is polarized, and is often presented as follows: metaphysics is either entirely extracted from science or it is entirely independent of science. There is a recent trend that focuses on the middle ground between these extremes, searching the philosophical literature for metaphysical theories that can fill the gap, i.e., leaving metaphysics as a free discipline to produce spoils for the eventual needs of philosophers of science. We can appreciate it better with the following distinction between the tasks of ontology and metaphysics, as complementary disciplines. If, on the one hand, we understand ontology as dealing with what exists, we can somehow extract the entities that are existentially postulated by scientific theories. Metaphysics, on the other hand, would be located as an extra layer, in charge of investigating questions about the nature of the entities obtained in this “naturalized ontology”. As a tailor, Wilson adjusts a metaphysical theory in order to perfectly dress the physical and ontological nuances of Everettian quantum mechanics, thus creating a metaphysical theory that gives us intelligibility, with the concept of modality, in two areas: in quantum mechanics, and analytic metaphysics

    Is Coronavirus an object? Metametaphysics meets medical sciences

    In ontological terms, what can we learn from the current state of the art in Epidemiology? Applying the Quinean criterion of ontological commitment, we can learn that there are several fundamental entities for the theory to work. One is a virus type entity, in which the (in)famous Coronavirus is a particular case. In metaphysical terms, this entity can, in principle, be understood in several ways. One of those ways, apparently, and perhaps intuitively, is the notion of object. Applying the metametaphysical method of Unavailable Metaphysical Stories, we found that Epidemiology is incompatible with an object metaphysics

    Taking models seriously and being a linguistic realist

    Full text link
    Carnap's conception of linguistic frameworks is widespread; however, it is not entirely clear nor consensual to pinpoint what is the influence in his stance within the traditional realist/anti-realist debate. In this paper, we place Carnap as a proponent of a scientific realist stance, by presenting what he called "linguistic realism". Some possible criticisms are considered, and a case study is offered with wave function realism, a popular position in the philosophy of quantum mechanics.Comment: To appear in Principia, vol. 26, n. 1, 2022: https://periodicos.ufsc.br/index.php/principia/inde

    The roads to non-individuals (and how not to read their maps)

    Get PDF
    Ever since its beginnings, standard quantum mechanics has been associated with a metaphysical view according to which the theory deals with non-individual objects, i.e., objects deprived of individuality in some sense of the term. We shall examine the grounds of the claim according to which quantum mechanics is so closely connected with a metaphysics of non-individuals. In particular, we discuss the attempts to learn the required `metaphysical lessons' required by quantum mechanics coming from four distinct roads: from the formalism of the theory, treating separately the case of the physics and the underlying logic; from the ontology of the theory, understood as the furniture of the world according to the theory; and, at last, we analyze whether a metaphysics of non-individuals is indispensable from a purely metaphysical point of view. We argue that neither non-individuality nor individuality is not to be found imposed on us in any of these levels so that it should be seen as a metaphysical addition to the theory, rather than as a lesson from it.Comment: Forthcoming in J.
