  1. Perfect Symmetries.Richard Healey - 2009 - British Journal for the Philosophy of Science 60 (4):697-720.
    While empirical symmetries relate situations, theoretical symmetries relate models of a theory we use to represent them. An empirical symmetry is perfect if and only if any two situations it relates share all intrinsic properties. Sometimes one can use a theory to explain an empirical symmetry by showing how it follows from a corresponding theoretical symmetry. The theory then reveals a perfect symmetry. I say what this involves and why it matters, beginning with a puzzle that is resolved by the (...)

  • Symmetry and Equivalence.Gordon Belot - 2013 - In Robert Batterman (ed.), The Oxford Handbook of Philosophy of Physics. Oxford University Press. pp. 318-339.
    This paper is concerned with the relation between two notions: that of two solutions or models of a theory being related by a symmetry of the theory and that of solutions or models being physically equivalent. A number of authors have recently discussed this relation, some taking an optimistic view, on which there is a suitable concept of the symmetry of a theory relative to which these two notions coincide, others taking a pessimistic view, on which there is no such (...)

  • Fundamentality, Effectiveness, and Objectivity of Gauge Symmetries.Aldo Filomeno - 2016 - International Studies in the Philosophy of Science 30 (1):19-37.
    UNOFFICIAL ABSTRACT It is not clear (to me at least) whether certain metaphysical questions really demand explanation. In this article I propose an argument for why fundamental laws of nature (of a form similar to those of the Standard Model) would welcome an explanation. The argument relies on Curie's first principle and on a feature of the current laws of particle physics. I also argue that this feature allows us to understand the ``unreasonable'' effectiveness of mathematics in physics (5.2) and (...)

  • Symmetry as an Epistemic Notion.Shamik Dasgupta - 2016 - British Journal for the Philosophy of Science 67 (3):837-878.
    Symmetries in physics are a guide to reality. That much is well known. But what is less well known is why symmetry is a guide to reality. What justifies inferences that draw conclusions about reality from premises about symmetries? I argue that answering this question reveals that symmetry is an epistemic notion twice over. First, these inferences must proceed via epistemic lemmas: premises about symmetries in the first instance justify epistemic lemmas about our powers of detection, and only from those (...)

  • Quantum Ontology in the Light of Gauge Theories.Gabriel Catren - unknown
    We propose the conjecture according to which the fact that quantum mechanics does not admit sharp value attributions to both members of a complementary pair of observables can be understood in the light of the symplectic reduction of phase space in constrained Hamiltonian systems. In order to unpack this claim, we propose a quantum ontology based on two independent postulates, namely the phase postulate and the quantum postulate. The phase postulate generalizes the gauge correspondence between first-class constraints and gauge transformations (...)
