faculty is a capacity or power for vital operation. Faculties are distinct from the substance which possesses and uses them, for the immediate exercise of vital operations. Some of man's faculties belong to the living body, some belong to the soul. These facts are the psychological basis for admitting faculties (from facere, to do), capacities ( capax, from capere, to hold), or powers (from posse, to be able; the Scholastics generally use the corresponding Latin term potentiæ).
