For and Against Metaphysics in the Modal Interpretation of Quantum Mechancis

In this paper we discuss the relation of quantum theory to the problem of metaphysics. Based on metaphysical and anti-metaphysical stances, we put forward an ‘interpretational map’ of quantum mechanics in general and of the modal interpretation in particular. Thus, within the modal interpretation, we distinguish between: Modal Interpretations (which start from) the Mathematical Formalism (MIMF) and Modal Interpretations (which start from) Metaphysical Principles (MIMP). Finally, we argue for a middle path in between metaphysical principles and the formal conditions imposed on quantum mechanics.
