Book excerpt: Nothing Mat(t)ers is a feminist critique of the theories of Foucault, Derrida, and Lacan, among others. Somer Brodribb analyzes the texts and the arguments that post-structuralism has nominated as central, in the process exposing the misogyny at their core. Brodribb provides a history of definitions of structuralism, post-structuralism, deconstruction, and postmodernism. She considers feminist encounters with structuralism and existentialism. She evaluates the originality of Foucault's contributions and discusses feminist responses to his work. Turning to Derrida, she considers his fixation with dissemination and demeaning versus conception and new embodiment. She contrasts the work of Lacan and Irigaray on ethics before turning to the work of de Beauvoir, O'Brien, and other feminists as an authentic alternative to postmodern critical theory.
