The present era of economic devastation, legacies of colonization and imperialism, climate change and habitat loss, calls for a new understanding of ethics. These essays on otherness, responsibility and hospitality raise urgent questions. Contributors range from the prominent--including Levinas, Michel Foucault, Jacques Derrida and Giorgio Agamben--to recent theorists such as Judith Butler, Enrique Dussell and Rosi Braidotti. The essays emphasize the always vulnerable status of a radically different Other, even as they question what responsibility to that Other might mean.
