Probing the Meaning of Quantum Mechanics: Probability, Metaphysics, Explanation and Measurement

This article examines the need for a comprehensive theory that explains the creation of the universe and the enigmatic behaviours observed in quantum particles. Recent advancements in quantum physics have revealed phenomena in the microscopic and macroscopic realms that challenge conventional explanations based solely on natural laws. This article introduces an argument centred on the concept of “presence of metaphysics in physics” as a means to provide a plausible account for the improbable existence of the universe and the mechanics of the space-time continuum. By incorporating ontological principles in classical physics and quantum mechanics, this proposed model sheds light on the origins of natural laws while also considering the mysterious balance and intricacies observed in micro and macrocosms. Moreover, this article argues that a mere succession of random events guided by mathematical probabilities cannot adequately establish and govern the natural laws that appear to have arisen with the aim of fostering life within the universe.

This chapter argues that the general philosophy of science should learn metaphilosophical lessons from the case of metaphysical underdetermination, as it occurs in non-relativistic quantum mechanics. Section 2 presents the traditional discussion of metaphysical underdetermination regarding the individuality and non-individuality of quantum particles. Section 3 discusses three reactions to it found in the literature: eliminativism about individuality; conservatism about individuality; eliminativism about objects. Section 4 wraps it all up with metametaphysical considerations regarding the epistemology of metaphysics of science.

Abstract Each formulation of quantum mechanics we consider in the book seeks to explain why we have determinate measurement records distributed according to the standard quantum statistics. The explanation we get relies on the metaphysical assumptions that underlie the particular theory. Metaphysics here does real explanatory work in accounting for our experience. While it is not at all clear what specific metaphysical commitments best explain our experience, one can distinguish between different types and degrees of empirical adequacy each formulation provides. Stronger notions of empirical adequacy might be characterized in terms of such things as the plausibility that one’s experience in fact supervenes on the sort of records a particular theory provides and the richness of the account of experience provided by the theory.
