Book excerpt: Horizons of Difference offers twelve original essays inspired by Luce Irigaray's complex, nuanced critique of Western philosophy, culture, and metaphysics, and her call to rethink our relationship to ourselves and the world through sexuate difference. Contributors engage urgent topics in a range of fields, including trans feminist theory, feminist legal theory, film studies, critical race theory, social-political theory, philosophy of religion, environmental ethics, philosophical aesthetics, and critical pedagogy. In so doing, they aim to push the scope of Irigaray's work beyond its horizon. Horizons of Difference seeks conversations that Irigaray herself has yet to fully consider and explores areas that stretch the limits of the notion of sexuate difference itself. Sexuate difference is a unifying mode of thought, bringing disparate disciplines and groups together. Yet it also resists unification in demanding that we continually rethink the basic coordinates of space, place, and identity. Ultimately, Horizons of Difference insists that the fragmented, wounded subjectivities within the dominant regime of masculine sameness can inform how we negotiate space, find place, and transform identity.
