On Quantum Things: A Constructive Guide to the Fundamentals of Quantum Theory

A realist, particle-based view of quantum theory-where the wavefunction no longer plays a central role-offers a clear, commonsense alternative to dominant metaphysical views.This book explores the metaphysics of quantum theory through a lens of scientific realism-the belief that successful scientific theories describe reality.It critically evaluates various interpretations, including structural realism, wave function realism, and the many-worlds view, highlighting their limitations.Valia Allori proposes a “spatiotemporal foundational ontology” approach, grounded in particles as fundamental entities evolving in three-dimensional space and time, following uniform, symmetric laws.This view is exemplified by Bohmian mechanics (pilot-wave theory), offering a constructive, commonsensical explanation of quantum phenomena.The wave function, in this framework, is not a physical object but plays a functional, law-like role in explaining interactions.Further, the book advances a radical thesis: f
