Care is a matter of responsibility for human and nonhuman allies, an ecological network. Care is an imperative, and acting with care approaches the world beyond selfhood. ON CARE, an aggregate of voices, discusses the politics of caring, support and the role of welfare in an increasingly neoliberal society. It questions who is seen as worthy of care, whose narratives are given attention, and whose lives are overlooked in a complex web of assemblages: conceptions of medical authority, the co-option of self-care in political rhetoric, care as a commodity in the hospitality industry, inter generational intimacy, sexecology; care as utopian and care as transactional. ON CARE maps a constellation of perspectives, as testaments, fictions, and essays, addressing the relation between good health, interdependence, and the ethics of (Self)care.
