Rovelli’s Relational Quantum Mechanics, Anti-Monism, and Quantum Becoming
Mauro Dorato
Abstract
In this chapter Rovelli’s relational interpretation of quantum mechanics (RQM) is defended from some foreseeable objections, so as to clarify its distinctive philosophical implications. In particular, the chapter considers whether RQM presupposes a duality of evolutions and of ontology (the relationality of quantum world and the intrinsicality of the classical world). It then concentrates on the pluralistic, anti-monistic metaphysical consequences of the theory, due to the impossibility of assigning a quantum state to the entire universe. Finally interesting consequences of RQM with respect to the possibility of defining a local, quantum relativistic becoming are noted. Given the difficulties with the cosmic form of becoming required by priority monism, RQM seems to present an important advantage with respect to monistic views, at least as far as the possibility of explaining our experience of time is concerned.
