Three Kinds of Metaphysical Indeterminacy

Lisa Vogt (University of Geneva)

This talk distinguishes between three different kinds of indeterminacy in the world and shows how they can be modeled within a unified framework in truthmaker-semantics: indeterminacy as fundamental incompleteness, indeterminacy as fundamental indecision, and merely derivative indeterminacy. As we will see, for any putative case of metaphysical indeterminacy, the resulting overall picture and the incurred metaphysical commitments differ substantially depending on which kind of metaphysical indeterminacy is used to understand the case. Modeling these distinctions allows us to acquire a more nuanced picture of the structure of indeterminacy and helps us to get clearer on the question of whether we should understand worldly indeterminacy as a phenomenon that concerns primarily the fundamental level.
