Herein, we embark on a journey from its awakenings back in the 1960s. We begin our quest with Kate Millett, we will continue our discussion with Irigaray, Cixous, or Kristeva and their analysis of the difference created by gender. And, we will reflect on the influence it has made to the American movement. We use the aforementioned as the lead towards the theory of deconstruction in authors such as Felman or Spivak, and how we reach the concept of performativity of gender in line with Butler and the queer theory.展开更多
