Judith Butler is an American philosopher and gender theorist. Butler’s work has influenced political philosophy, ethics, and the fields of third-wave feminism, queer theory, and literary theory. She argued that gender is a social construct, which is performed rather than adopted. Because gender identity is established through behaviour, there is a possibility to construct different genders via different behaviours. Butler offers a critique of the terms gender and sex as they have been used by feminists. Butler argues that feminism made a mistake in trying to make “women” a discrete, ahistorical group with common characteristics. Butler writes that this approach reinforces the binary view of gender relations. Butler believes that feminists should not try to define “women” and they also believe that feminists should “focus on providing an account of how power functions and shapes our understandings of womanhood not only in the society at large but also within the feminist movement. Judith herself is a lesbian, whose legally non-binary, and goes by she or they pronouns.
