Some of the language we come across, in reading other peoples' works or listening to others speak, moves us profoundly. It requires a response from us; it occupies and involves us. Writers, always readers and listeners as well, are fascinated by this phenomenon, which became the subject of the classical treatise On the Sublime , traditionally attributed to Longinus. Emma Gilby looks at this compelling and complex text in relation to the work of three major seventeenth-century authors: Pierre Corneille, Blaise Pascal and Nicolas Boileau. She offers, in each case, intimate critical readings which spin out into broad interrogations about knowledge and experience in early modern French literature.
