After completing an essay entitled Traité de la Volonté ("Treatise on the Will"), Lambert is horrified when a teacher confiscates it, calls it "rubbish", and – the narrator speculates – sells it to a local grocer. Soon afterwards, a serious illness forces the narrator to leave the school. In 1815, Lambert graduates at the age of eighteen and lives for three years in Paris. After returning to his uncle's home in Blois, he meets a woman named Pauline de Villenoix and falls passionately in love with her. On the day before their wedding, however, he suffers a mental breakdown and attempts to castrate himself.
