LTT: Mike Hicks Tuesday, September 29th @ 12:00 pm - 1:30 pm EST Title: Pragmatic Realism about Modality, Natural and Metaphysical Abstract: Modal notions—which deal with necessity, possibility, and counterfactually robust conditionals–are central to our explanatory, predictive, and practical decision-making activities. In this talk, I will focus on two distinct types of modality: first, natural modality, the sort associated with causation, laws of nature, and scientific explanation; and second, metaphysical modality, of the sort associated with essences, semantic externalism, and grounding explanation. I will present and defend a first-order realist, higher-order pragmatist view of these modal notions. On this view, modal notions are backed by real, in the world relations: invariant regularities in the case of natural modals, and identity-like relations in the case of metaphysical modals. What makes these relations modal, however, are facts about our inferential practices. A relation is modally robust, on this view, just in case (and because) it is suitable to back a pattern of truth-conducive deductive inferences. I argue that this higher-order pragmatic explanation of the modality of these relations doesn’t challenge the view’s first-order realism, but does provide the view with the resources to solve some of realism’s more intractable normative and epistemic problems.
