Differences That Matter challenges theories of the relationship between feminism and postmodernism that ask is/should feminism be modern or postmodern? Pointing out how postmodernism has been allowed to dictate feminist debates, Sara Ahmed argues instead that feminism must itself ask questions of postmodernism; that feminist theorists speak (back) to postmodernism rather than simply speak on (their relationship to) it. This speaking back involves a refusal to position postmodernism as a generalizable condition of the world, using close readings of postmodern constructions of rights, ethics, woman, subjectivity, authorship and film.
