Christine Delphy (born 1941) is a French sociologist, feminist, writer and theorist. She was a co-founder of the review Nouvelles questions féministes (New Feminist Issues) with Simone de Beauvoir in 1977.
Delphy studied sociology at the University of Paris and the University of California, Berkeley. She worked in 1965 for the Washington Urban League then began working for Centre National de Recherche Scientifique (CNRS) in Paris in 1966. After May 1968 events, Christine Delphy took part in the women's liberation movement (Mouvement de Libération des Femmes called MLF) and was one of the few women who brought flowers to the "wife of the unknown soldier" in August 1970. It was the first action of the MLF that received attention in the medias. Delphy is openly lesbian. She was a member of the Gouines rouges ("Red Lesbian").
Delphy's works are mostly about feminism and class-struggle issues. She created Material feminism, which is not just socialist feminism but applies a materialist approach to gender relations. For Karl Marx class is a position in the mode of production; for Delphy gender is also a position in the mode of production (domestic labour). So the main enemy of women is not capitalism but patriarchy. The sex comes after the gender (hierarchy) and is used to legitimate the domination.
Christine Delphy had a big influence on Monique Wittig, who had a big influence on Judith Butler. But Judith Butler de-emphasizes materialist analysis. For her, women are principally a cultural construction. Christine Delphy writes that this 'cultural turn' has dismissed the very real oppression of women.
Against Essentialism and the so-called "French Feminism"
Delphy challenges the biological essentialist view of gender and fights against essentialism, even when it comes from the women's movement. She also fights against what she called "the invention of 'french Feminism'": Most French feminists are against essentialism and very few support what was called "French Feminism" in the United States. For Delphy, the American invention of "French Feminism" had a political purpose: the acceptance of essentialism among Anglo-American feminists (it was expected they would think, If French women think this way, we have to respect/accept this.
