The world is facing crises in global politics and international relations that have only recently begun to be discussed in the philosophical literature. There is a crisis in peace highlighted by the so-called war on terror (Sterba 2003b). There is a refugee crisis with people moving around the globe in unprecedented numbers driven by war, persecution, famine and economic hardship (Carens 1987; Goodin 1992; Boswell 2005). There is a crisis of global justice with entire populations in underdeveloped parts of the world facing the threat of starvation owing to avoidable poverty. There is a global environmental crisis, of which climate change is only the most widely debated consequence (Jonas 1984; Crocker & Linden 1998; Newton 2003). There is a crisis in the global economy with the high social costs of globalization and trade as well as threats to supplies of energy resources (Sen 1999).
