- The paper investigates the famous Searlean distinction between "brute" and "institutional" concepts from a logical point of view. We show how the partitioning of the non-logical alphabet—e.g., into "brute" and "institutional" atoms—gives rise to interesting modal properties. A modal logic, called UpTo-logic, is introduced and investigated which formalizes the notion of (propositional) logical equivalence up to a given signature.
