Book excerpt: R. M. Hare writes in his Preface: 'I offer this taxonomy of ethical theories to all those who are lost in the moral maze, including many of my philosophical colleagues. They are lost because, like most of those who hold forth on moral questions in the media, they have no map of the maze. This is has been my aim to provide.' Sorting Out Ethics is a characteristically lucid and lively survey of rival ethical theories by one of the most influential moral philosophers of the century. It also constitutes a definitive summary of Hare's own fundamental ethical position.
