Marie Robert's philosophical journey began with the question, "Does thinking about death help life?" This existential inquiry became a turning point in her life, prompting her to study philosophy at the Sorbonne after high school. She later taught at Paris V University and wrote her first book, a philosophical work with a pedagogical and playful tone, titled Kant tu ne sais quoi faire… il reste la philo (Flammarion / Versilio 2018). The book explores how philosophers might handle everyday situations, such as what Spinoza might do at IKEA. Her frequent visits to IKEA were part of a professional project at the time, which involved setting up an alternative school with her future husband. The school, initially based on her experience at the only Montessori high school in France, now has eight locations. Marie Robert's passion for sharing knowledge, whether through teaching or writing, is closely linked to her interest in language, particularly the work of Ludwig Wittgenstein, which she specialized in after her master's degree. Her goal is to make language accessible to everyone, a challenge that remains relevant for her as a popularizer of philosophy. She uses various platforms, such as her podcast Philosophy is sexy and Instagram posts, to engage people's minds. Her new book, La puissance du lien, continues this mission by making complex questions accessible and directly addressing the reader. Her writing style is characterized by a sense of connection, possibly inherited from her family of artisans and merchants, combined with a love for storytelling, which she describes as a "familial tropism" due to the many novels read at home. In La puissance du lien, she acts as a life coach, offering practical advice enriched by profound knowledge of both classical and contemporary authors, including Aristotle, Kierkegaard, Arendt, Éric Fiat, Byung-chul Han, and Sophie Galabru. The book explores various aspects of human connection through chapters on different stages of personal and social life, such as "making a couple," "making a family," "making a team," and "making a society." Each chapter ends with introspective exercises inspired by the spiritual exercises of Saint Ignace de Loyola, emphasizing the importance of small, patient, and often invisible actions in building meaningful relationships. These include small gestures, words, and acts of recognition, such as saying "hello" or "thank you" with someone's name.
