Is it rational to be moral? Can moral disputes be settled rationally? Which criteria determine what we have a good reason to do? In this innovative book, Logi Gunnarsson takes issue with the assumption made by many philosophers faced with the problem of reconciling moral norms with a scientific world view, namely that morality must be offered a non-moral justification based on a formal concept of rationality. He argues that the criteria for the rationality of an action are irreducibly substantive, rather than purely formal, and that assuming that morality must be given a non-moral justification amounts to a distortion of both rationality and morality. His discussion includes substantial critical engagement with major thinkers from two very different philosophical traditions, and is notable for its clear and succinct account of Habermas' discourse ethics. It will appeal to anyone interested in practical reason and the rational credentials of morality.

As witnessed by recent films such as Fight Club and Identity, our culture is obsessed with multiple personality-a phenomenon raising intriguing questions about personal identity. This study offers both a full-fledged philosophical theory of personal identity and a systematic account of multiple personality. Gunnarsson combines the methods of analytic philosophy with close hermeneutic and phenomenological readings of cases from different fields, focusing on psychiatric and psychological treatises, self-help books, biographies, and fiction. He develops an original account of personal identity (the authorial correlate theory) and offers a provocative interpretation of multiple personality: in brief, "multiples" are right about the metaphysics but wrong about the facts.

In their contributions, the authors connect general philosophical reasoning about the foundational role of human dignity for human rights with more concrete demands as to how to deal with basic human needs and to end poverty. These legal and political arguments are based on recent rulings of regional courts and international human rights bodies. They discuss obligations that result from human rights and ask which institutions or corporations are responsible for their realisation.
