The exertion of an inherent power
The expression was keenly intellectual
The facile conjectures of ignorant onlookers
The facts took him by the throat
The fitful swerving of passion
The flabbiness of our culture
The flaccid moods of prose
The flame of discord raged with redoubled fury
The flattest and most obvious truisms
The flippant insolence of a decadent skepticism
