Quantum relational indeterminacy

Abstract

The paper presents the first thorough investigation of quantum metaphysical indeterminacy (MI) in the context of the Relational Interpretation of Quantum Mechanics (RQM). We contend that the interaction between MI and RQM is mutually beneficial. On the one hand, MI provides a metaphysical framework for RQM that has been neglected in the literature, and that promises to undermine some objections that are often raised against RQM. On the other hand, RQM might serve as an example of fundamental quantum MI.
