In 1931, at just twenty-two years of age and having recently qualified as an *agrégée* in philosophy, Simone Weil began her teaching career in Le Puy-en-Velay. There, while actively engaging in social struggles and discovering the reality of the working class, she developed a teaching style that made a lasting impression on her students through her commitment and intellectual honesty. Notes taken by two of these students -- Yvette Argaud and Elisabeth Chanel -- partially reviewed by Weil herself and edited decades later by scholars of her work, now allow us to access these exceptional lessons. The volume is further enriched by previously unpublished documents and firsthand accounts from those who knew this unforgettable teacher. What is philosophy, and what is its purpose? In these pages, Simone Weil offers an answer that remains as relevant as ever: philosophy inspires action; it is a form of knowledge that places human beings at the center of everything, teaching us how to think, how to use language well, and how to live with greater clarity. It is an invitation to examine our way of being in the world.
