How does Judith Butler`s speech act theory help us to read Gertrude Stein, Lyn Hejinian and Rosmarie Waldrop`s language-centered poetry? In this paper, I seek to demonstrate how Butler`s theory in particular her concepts of “performative” and “perlocutionary” language allows us to discern and describe different types of female subjectivity in Stein, Hejinian, and Waldrop`s experimental writings. Their poetic languages are good examples of Butler`s notion of the “differently” enacted and repeated language of misconception. Instead of having fantasies about Adam`s language before the Tower of Babel, they use their unpredictable languages to benefit those who are in subordinate positions in the realm of language, including women. By giving such people chances to revise, recreate, and restage the signifiers in different contexts, these female avant-gardists attempt to reconstruct speaking subjects as infinitely alternative subjects. And this vulnerability further opens up the possibility of counter-speeches against conventional ones, bringing some disruption in existing gender power dynamics and creating an alternative speaking subject.
