A Minimal Characterization of Indeterminacy

The current literature on indeterminacy centers around two (related) projects. One concerns the logic of indeterminacy; the other concerns its nature or source. The aim of this paper is to introduce, motivate and go some way toward addressing a new, third project: that of providing what I call a minimal characterization (MC) of indeterminacy. An MC, to a first approximation, is a relatively pre-theoretical characterization of indeterminacy that is neutral between the various substantive theories of the nature and logic of indeterminacy. An MC thus captures a generic sense of indeterminacy that, at least in principle, is recognized by all parties to the debate over the phenomenon’s underlying nature and logic. I begin by introducing the concept of an MC and outlining some of the main theoretical virtues of providing an MC. I then establish some desiderata on a suitable MC, and use these desiderata to rule out various initially attractive proposals. In the final part of the paper I sketch the beginnings of my own MC and defend it against objections.
