Abstract: Many solutions have been proposed for solving the problem of macroscopic superpositions of wave function ontology. A possible solution is to assume that, while the wave function provides the complete description of the system, its temporal evolution is not given by the Schroedinger equation. The usual Schroedinger evolution is interrupted by random and sudden “collapses”. The most promising theory of this kind is the GRW theory, named after the scientists that developed it: Gian Carlo Ghirardi, Alberto Rimini and Tullio Weber. It seems tempting to think that in GRW we can take the wave function ontologically seriously and avoid the problem of macroscopic superpositions just allowing for quantum jumps. In this paper it is argued that such “bare” wave function ontology is not possible, neither for GRW nor for any other quantum theory: quantum mechanics cannot be about the wave function simpliciter. All quantum theories should be regarded as theories in which physical objects are constituted by a primitive ontology. The primitive ontology is mathematically represented in the theory by a mathematical entity in three-dimensional space, or space-time.
Comment: This is a very interesting article on the ontology of Quantum Mechanics. It is recommended for advanced courses in Philosophy of Science, especially for modules in the Philosophy of physics. Previous knowledge of Bohmian mechanics and the Many Words Interpretation is necessary. Recommended for postgraduate students.[This is a stub entry.

Abstract: The aim of this paper is to summarize a particular approach of doing metaphysics through physics – the primitive ontology approach. The idea is that any fundamental physical theory has a well-defined architecture, to the foundation of which there is the primitive ontology, which represents matter. According to the framework provided by this approach when applied to quantum mechanics, the wave function is not suitable to represent matter. Rather, the wave function has a nomological character, given that its role in the theory is to implement the law of evolution for the primitive ontology.
Comment: This article works well as a secondary reading since it refers to specific theories of physics. Previous knowledge on the cornerstones of philosophy of physics is needed.[This is a stub entry.
