Christine Battersby rethinks questions of embodiment, essence, sameness and difference, self and other, patriarchy and power. Using analyses of Kant, Adorno, Irigaray, Butler, Kierkegaard and Deleuze, she challenges those who argue that a feminist metaphysics is a a contradiction in terms. This book explores place for a metaphysics of fluidity in the current debates concerning postmodernism, feminism and identity politics.
