Query: The Meaning of the Wave Function: In Search of the Ontology of Quantum
  Mechanics   The meaning of the wave function has been a hot topic of debate since the
early days of quantum mechanics. Recent years have witnessed a growing interest
in this long-standing question. Is the wave function ontic, directly
representing a state of reality, or epistemic, merely representing a state of
(incomplete) knowledge, or something else? If the wave function is not ontic,
then what, if any, is the underlying state of reality? If the wave function is
indeed ontic, then exactly what physical state does it represent? In this book,
I aim to make sense of the wave function in quantum mechanics and find the
ontological content of the theory. The book can be divided into three parts.
The first part addresses the question of the nature of the wave function
(Chapters 1-5). After giving a comprehensive and critical review of the
competing views of the wave function, I present a new argument for the ontic
view in terms of protective measurements. In addition, I also analyze the
origin of the wave function by deriving the free Schroedinger equation. The
second part analyzes the ontological meaning of the wave function (Chapters 6,
7). I propose a new ontological interpretation of the wave function in terms of
random discontinuous motion of particles, and give two main arguments
supporting this interpretation. The third part investigates whether the
suggested quantum ontology is complete in accounting for our definite
experience and whether it needs to be revised in the relativistic domain
(Chapters 8, 9).
