STOLIDITY — [Noun] The quality or state of being unemotional, impassive, or showing little sensibility. From the Latin stolidus ("dull, stupid, inert") + the suffix -itas ("-ity"), via Late Latin stoliditas and Middle French stolidité. Unlike "apathy," which implies a cool vacancy of interest, or "composure," which suggests a poised and conscious mastery of feeling, stolidity is a native, bovine impassiveness. It is the unblinking gaze of an ox at the plough, the unmoved set of a granite cliff in a gale, and the steady, unvarying heat from a banked fire long into the night—a monumental calm that feels less like a virtue than a geology, a fortress of self that mistakes its own silence for strength.
