Book review

Simon Friederich’s Therapeutic Approach1 to quantum theory (QT) sheds new light on the status of the quantum state. In particular, Friederich presents revisionary ideas on how to exactly differentiate objective from subjective elements of the theory and thereby improves upon previous stabs at an epistemic interpretation of quantum states. The book not only provides interesting perspectives for the cognoscenti but is also written with sufficient care and free of unnecessary technicalities so as to be accessible and worth reading for the physical layman interested in the foundations of QT. The main achievement of the book is an innovative outline for interpreting quantum states epistemically while avoiding many problems of previous attempts.

Part I (chapters 1–3) introduces the general formalism along with the measurement problem (MP), argues that the collapse postulatedoes not provide a solution to the MP since an instantaneous, objective collapse raises well-known problems with...



I thank Simon Friederich for illuminating exchange on details of his book.
