Simone de Beauvoir’s readers who saw a heterosexual ideal in her relationship with Jean-Paul Sartre must have been dismayed by the 1990 French publication of her Journal de guerre (Wartime Diary) and Lettres à Sartre (Letters to Sartre). Discovered after Beauvoir’s death in 1986 and edited for publication by her adopted daughter, Sylvie Le Bon de Beauvoir, Beauvoir’s Wartime Diary and Letters to Sartre recount her sexual affairs with several young women. In Deirdre Bair’s authorized biography of Beauvoir, also published (...) in 1990, Bair describes the young women in question as merely Beauvoir’s friends and reports that Beauvoir denied having sexual relationships with women (Bair 1990, 213-15, 510). With the publication of the wartime diary and letters, Beauvoir’s readers and her biographer were thus confronted with the uncomfortable revelation that Beauvoir had lied to them about her sexual relationships. -/- Given society’s attitudes towards bisexuality, Beauvoir’s lies about her relationships with women may be understandable. But evidence, first discovered in Beauvoir’s and Sartre’s wartime diaries and letters by Edward Fullbrook, that Beauvoir lied about her work in philosophy and her influence on Sartre, is more perplexing (Fullbrook and Fullbrook 1993, 97-127; Fullbrook 1999). Beauvoir earned a graduate agrégation degree in philosophy and authored numerous philosophical novels and essays. But her philosophical work, including her metaphysical novel, She Came to Stay (1943)—the story of an unconventional solipsist who, forced to recognize the existence of other minds, resorts to murder as a solution to the problem of the Other—has traditionally been dismissed as a literary application of Sartre’s philosophy in Being and Nothingness (1943), a view paradoxically encouraged by Beauvoir herself. While the evidence that Beauvoir lied about her work in philosophy may be disconcerting, it does open up new areas of research, as I’ll suggest below, raising questions about her philosophy in She Came to Stay, her philosophical relationship with Sartre, and the wartime transformation in her philosophy that were foreclosed by the traditional reading of Beauvoir as Sartre’s follower. -/- .
