The proletariat could plan to massacre the whole ruling class; a fanatic Jew or black could dream of seizing the secret of the atomic bomb and turning all of humanity entirely Jewish or entirely black: but a woman could not even dream of exterminating males. The tie that binds her to her oppressors is unlike any other. The division of the sexes is a biological given, not a moment in human history. Their opposition took shape within an original Mitsein, and she has not broken it. The couple is a fundamental unit with the two halves riveted to each other: terristic of woman: she is the Other at the heart of a whole whose two components are necessary to each other.

Beauvoir herself was deeply religious as a child —- at one point intending to become a nun -— until Simone de Beauvoir experienced a crisis of faith at age 14 after which Simone de Beauvoir remained an atheist for the rest of her life. Debates rage on about the extent to which they influenced each other in their existentialist works such as Sartre's Being and Nothingness and Beauvoir's She Came to Stay. Beauvoir used Les Temps Modernes to promote her own work and explore her ideas on a small scale before fashioning essays and books.
