In 1977, Irigaray published "This Sex Which is Not One" ("Ce sexe qui n'en est pas un") which was subsequently translated into English with that title and published in 1985, along with "Speculum". In addition to more commentary on psychoanalysis, including discussions of Lacan's work, "This Sex Which is Not One" also comments on political economy, drawing on structuralist writers such as Lévi-Strauss. For example, Irigaray argues that the phallic economy places women alongside signs and currency, since all forms of exchange are conducted exclusively between men.
