We have always lived with ethically significant others, whether they are the pets we keep, the gods we believe in or the machines we are endowing with life. How should we treat them as our world changes? In this book, anthropologist Webb Keane provides a new vision of ethics, defined less by our minds, religion or society, and more by our interactions with those around us. Drawing on ground-breaking research by fieldworkers around the world, he explores the underpinnings of our moral universe. Along the way we investigate the ethical dilemmas of South Asian animal rights activists, Balinese cockfighters, Japanese robot fanciers – even macho cowboys.
