A supplementary FraMEPhys Seminar was given by project visitor Dan Marshall (Lingnan University) on Monday 10th June 2019.
Dan’s title was “Facts and Grounding”.
Abstract: The most popular theories of the individuation conditions of facts are the coarse-grain theory, according to which facts are identical if and only if they are necessarily equivalent, and the structure theory, according to which facts are structured in the same kind of way sentences are structured. Despite their popularity, both these theories have serious problems. In this paper, I propose a new moderate-grain theory of facts that avoids these problems by individuating states of affairs more finely than the coarse-grain theory and more coarsely than the structure theory. I then defend the proposed theory from the objection that it is incompatible with widely accepted principles of grounding by arguing that these principles of grounding are false and should be replaced with alternative principles.
