This thesis contributes to critical theoretical interpretation of Sophocles' Antigone. Analyzing texts by Kelly Oliver, Jacques Lacan, and Judith Butler, the thesis demonstrates how the work of these writers re-installs oppositional binarism, the form of thought that undergirds the hierarchical structure of Western metaphysics as exemplified in the dialectical philosophy of G. W. F. Hegel. Focusing on texts by Carol Jacobs, Martin Heidegger, and Jacques Derrida, the thesis analyzes the performative effect of Antigone, as sister figure, in the graphics of these works. Employing a deconstructive and performative critical approach, the thesis explores the theoretical productivity of a "sororal" graphics, that, dispersing and subverting binarism, opens the texts and their interpretation to alterity. The thesis demonstrates how critical reading of the performativity of Antigone as sister figure implicates ethicological discussion on justice in relation to family, genre/gender, classification, and inheritance.
