This article takes as its point of departure Luce Irigaray's Elemental Passions, in which a woman‐speaker tries to make her lover and the discipline of philosophy understand that she is not how they have imagined her to be; that she is not at all but that she keeps becoming through perpetual movement. The article investigates Irigaray's investment in a form of materialist difference feminism that offers conceptual links to the posthumanist work of Karen Barad's agential realism, especially her theorization of intra‐action. The link between Irigaray and Barad is established via a diffractive reading that incorporates the dance/movement research practice of Contact Improvisation. Although expressed through written language, Elemental Passions creates the impression of the woman‐speaker dancing, of encountering herself, her environment, and her lover through moved and moving contact, searching for a practice of moving‐together, feeling‐with, and feeling‐between that can be experienced in an improvised dance duet. Exploring how touch and the sharing of weight in Contact Improvisation challenges boundaries and establishes ever‐changing configurations and entanglements between dancers, the article proposes that Irigaray's woman‐speaker envisions herself as a posthuman/ist woman and that improvised dancing offers a practice of intra‐action through which she can encounter the world in her becoming.
