While postmodern approaches to politics and ethics have offered some intriguing and influential insights in philosophy and theory, Gary Steiner illuminates the fundamental inability of these approaches to arrive at viable ethical and political principles. Ethics require notions of self, agency, and value that are not available to postmodernists. Therefore much of what is published under the rubric of theory lacks a proper basis for a systematic engagement with ethics.Steiner provocatively critiques postmodernist approaches to the moral status of animals against the background of a broader indictment of postmodern thought and its inability to establish clear principles for action. He revisits the work of Derrida, Foucault, Nietzsche, and Heidegger, together with recent work by their American interpreters, and shows that the basic terms of postmodern thought are incompatible with any definitive claims about the moral status or rights of animalsand humans. Steiner acknowledges the failures of liberal humanist thought regarding the moral status of animals; but instead of following postmodern thinkers who reject humanist thought outright, he argues for the need to rethink humanist notions in a way that avoids the anthropocentric limitations of traditional humanist thought. Drawing on the achievements of the Stoics and Kant, Steiner builds on his earlier work, developing his ideas of cosmic holism and non-anthropocentric cosmopolitanism in order to arrive at a more concrete foundation for animal rights.
