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.
