Modal perspectivalism

There are limits to how things might have been. Yet tiny permissible differences between possibilities add up to large ones that exceed those limits. This tension lies at the heart of the so-called tolerance puzzle. In this paper, I propose a novel response grounded in the idea that metaphysical modality is perspectival. The perspectivalist framework is used to dissolve the puzzle and is contrasted with two alternatives: one that posits a plenitude of finely individuated entities, and another that appeals to a double relativization of modal claims—both to a world considered as actual and to a world considered as counterfactual.
