“It is quite incorrect to believe that the dead are gone forever and never return to speak to the living. They return to speak to the living all the time; indeed, it is their main activity.” Thus writes Sylvie Weil in this illuminating memoir, in which contemporary readers can hear the voices of her famed philosopher aunt Simone and mathematician father André. Born into a freethinking Jewish family in France in 1909, Simone Weil was one of the twentieth century’s most original philosophers, influencing Albert Camus, T. S. Eliot, Simone de Beauvoir, Pope John XXIII, Czeslaw Milosz, and Susan Sontag. She fought for workers’ rights and, later, the Spanish Republican cause. Before her death at age thirty-four, Simone Weil turned increasingly to mysticism and religion, especially Roman Catholicism, exploring themes of sacrifice, asceticism, and the virtues of manual labor. She never converted, however, and Sylvie Weil writes from a Jewish perspective, emphasizing Simone’s Jewish heritage. Using previously unpublished family correspondence and conversations, Sylvie Weil paints the most vivid, private portrait of her aunt in print. The book illuminates Simone’s relationship with others, especially with her brother, André. Loving and unsparing, affectionate and incisive, At Home with André and Simone Weil is an insightful memoir about a family of intellectual luminaries.
