Judith Butler's new book shows how an ethic of nonviolence must be connected to a broader political struggle for social equality. Further, it argues that nonviolence is often misunderstood as a passive practice that emanates from a calm region of the soul, or as an individualist ethical relation to existing forms of power. But, in fact, nonviolence is an ethical position found in the midst of the political field. An aggressive form of nonviolence accepts that hostility is part of our psychic constitution, but values ambivalence as a way of checking the conversion of aggression into violence. One contemporary challenge to a politics of nonviolence points out that there is a difference of opinion on what counts as violence and nonviolence. The distinction between them can be mobilised in the service of ratifying the state's monopoly on violence.
