  1. Disappearance and emergence of space and time in quantum gravity.Daniele Oriti - 2014 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 46 (2):186-199.
    We discuss the hints for the disappearance of continuum space and time at microscopic scale. These include arguments for a discrete nature of them or for a fundamental non-locality, in a quantum theory of gravity. We discuss how these ideas are realized in specific quantum gravity approaches. Turning then the problem around, we consider the emergence of continuum space and time from the collective behaviour of discrete, pre-geometric atoms of quantum space, and for understanding spacetime as a kind of “condensate”, (...)

    Levels of spacetime emergence in quantum gravity.Daniele Oriti - 2021 - In Christian Wüthrich, Baptiste Le Bihan & Nick Huggett, Philosophy Beyond Spacetime: Implications From Quantum Gravity. Oxford: Oxford University Press. pp. 16-40.
    We explore the issue of spacetime emergence in quantum gravity, by articulating several levels at which this can be intended. These levels correspond to the reconstruction moves that are needed to recover the classical and continuum notion of space and time, which are progressively lost in a progressively deeper sense in the more fundamental quantum gravity description. They can also be understood as successive steps in a process of widening of the perspective, revealing new details and new questions at each (...)

    Tightrope-Walking Rationality in Action: Feyerabendian Insights for the Foundations of Quantum Mechanics.Daniele Oriti - 2024 - International Studies in the Philosophy of Science 37 (4):161-193.
    We scan Paul K. Feyerabend's work in philosophy of physics and of science more generally for insights that could be useful for the contemporary debate on the foundations of quantum mechanics. We take as our starting point what Feyerabend has actually written about quantum mechanics, but we extend our analysis to his general views on realism, objectivity, pluralism, and the relation between physics and philosophy, finding that these more general views could in fact offer many interesting insights for physicists and (...)

    Epistemic–Pragmatist Interpretations of Quantum Mechanics: A Comparative Assessment.Ali Barzegar & Daniele Oriti - 2024 - Foundations of Physics 54 (5):1-34.
    In this paper, we investigate similarities and differences between the main neo-Copenhagen (or “epistemic–pragmatist”) interpretations of quantum mechanics, here identified as those defined by the rejection of an ontological nature of the quantum states and the simultaneous avoidance of hidden variables, while maintaining the quantum formalism unchanged. We argue that there is a single general interpretive framework in which the core claims that the various interpretations in the class are committed to, and which they emphasize to varying degrees, can be (...)

    The Bronstein hypercube of quantum gravity.Daniele Oriti - unknown
    We argue for enlarging the traditional view of quantum gravity, based on ‘quantizing GR’, to include explicitly the non-spatiotemporal nature of the fundamental building blocks suggested by several modern quantum gravity approaches, and to focus more on the issue of the emergence of continuum spacetime and geometry from their collective dynamics. We also discuss some recent developments in quantum gravity research, aiming at realising these ideas, in the context of group field theory, random tensor models, simplicial quantum gravity, loop quantum (...)

    No alternative to proliferation.Daniele Oriti - unknown
    We reflect on the nature, role and limits of non-empirical theory assessment in fundamental physics, focusing in particular on quantum gravity. We argue for the usefulness and, to some extent, necessity of non-empirical theory assessment, but also examine critically its dangers. We conclude that the principle of proliferation of theories is not only at the very root of theory assessment but all the more necessary when experimental tests are scarce, and also that, in the same situation, it represents the only (...)

    The quantum gravity seeds for laws of nature.Vincent Lam & Daniele Oriti - 2024 - European Journal for Philosophy of Science 14 (4):1-23.
    We discuss the challenges that the standard (Humean and non-Humean) accounts of laws face within the framework of quantum gravity where space and time may not be fundamental. This paper identifies core (meta)physical features that cut across a number of quantum gravity approaches and formalisms and that provide seeds for articulating updated conceptions that could account for QG laws not involving any spatio-temporal notions. To this aim, we will in particular highlight the constitutive roles of quantum entanglement, quantum transition amplitudes (...)

    A minimalist account of agency in physics.Ali Barzegar, Emilia Margoni & Daniele Oriti - manuscript
    We adopt a top-down approach to agency aimed at developing a minimalist, scalable and naturalized account of it. After providing a general definition, we explore some possible extensions and refinements, domain of applicability, as well as a comparison with other recent accounts of agency, and possible objections to our proposal. With respect to what we classify as strong (such as Tononi’s) and weak (such as Rovelli’s) characterizations, our notion of agency situates itself in a middle position – our intent being (...)
