Sobriety in literature is a multifaceted term that goes well beyond a mere absence of intoxication. It often connotes a quality of firmness, measured judgment, and self-possession—as when Augustine marvels at the “solidity” and “consistency” of an argument ([1]) or when Gibbon lauds a ruler's temperance in his historical narrative ([2]). At times, authors equate sobriety with moral rectitude and mental clarity, imbuing characters with a reserved dignity or a deliberate calm as seen in Brontë’s reflective prose ([3]) and in the ethical exhortations of Plutarch ([4]). Meanwhile, in character portrayals and social observations—from Casanova’s self-critical excessive sobriety ([5]) to the understated, soldier-like restraint described in a military setting ([6])—the term serves as a versatile emblem for moderation, intentionality, and the measured conduct that underscores both personal virtue and literary style.
