This book pursues an investigation at the intersection of philosophy of physics and philosophy of language, and offers a critical analysis of rival explanations of the semantic facts of quantum mechanics. The author presents new insights, including a reworking of Einstein''s incompleteness argument, a fresh take on Bohr''s correspondence principle, and several critiques of recent views in the philosophy of quantum logic. The book will be of interest to scholars and students whose philosophical work concerns language, logic, or physics.
