This book brings together a group of Judith Butler's philosophical essays written over two decades that elaborate her reflections on the roles of the passions in subject formation. Working with theories of embodiment, desire, and relationality in conversation with philosophers as diverse as Hegel, Spinoza, Descartes, Merleau-Ponty, Freud, and Fanon, Butler reanimates and revises her basic propositions concerning the constitution and deconstitution of the subject within fields of power, taking up key issues of gender, sexuality, and race in several analyses.
