A New Modal Interpretation of Quantum Mechanics in Terms of Relational Properties

Abstract

In this paper we propose a new modal interpretation of quantum mechanics, wherein quantum states assign to systems relational rather than intrinsic properties. We argue that this relational modal interpretation overcomes the major problems encountered by current modal interpretations. In particular, we explain how this new interpretation addresses the measurement problem and accounts for our experience of the classicallike behavior of macroscopic systems. We further provide an outline for the dynamics of relational properties, and demonstrate how this dynamics circumvents all the no-go theorems for relativistic modal interpretations. Finally, we discuss the difficulties and the prospects of providing a genuinely relativistic modal interpretation.
