Judith Butler is one of the more extensively contemporary authors who has addressed the problematization of the subject from a feminist-queer and antiessentialist perspective, showing that the subject is not a closed and fully established category but a process of continuous construction and open to rearticulations constant. We may wonder, therefore, how J. Butler explains this process of construction of the subject and identity from an antiessentialist perspective and, more specifically, what she refers by stating that the subject is constructed? What means understanding the subject as construction?
