In this article on Elizabeth Grosz's philosophy and its implications for discussions about feminist theory, I first suggest that Charles Darwin plays a particular role in Grosz's recent ontological thought. This role is to provide help in joining together two incompatible sources in her work: Gilles Deleuze's monistic ontology of a constant flow of new differentiations, on the one hand, and Luce Irigaray's thought of sexual difference as the primary ontological difference, on the other. I argue that Grosz's intellectual project (...) has developed into a grand general theory of change in which both Darwin and Irigaray are turned into ontologists in a Deleuzian vein. I then point out that Grosz's ontology also includes a political aspect, which manifests in the fact that Grosz redescribes Darwin through interpreting him primarily as a theorist of “event” and the unexpected. However, through an analysis of the discussion on Grosz between Luciana Parisi and Jami Weinstein, I speculate whether Grosz's ambition to provide a total and complete explanation of change encourages the tone of feminist discussion toward one of explanation rather than intervention.
