Coady explores the challenges that morality poses to politics. He confronts the complex intellectual tradition known as realism, which seems to deny any relevance of morality to politics, especially international politics. He argues that, although realism has many serious faults, it has lessons to teach in particular, it cautions us against the dangers of moralism in thinking about politics and particularly foreign affairs. Morality must not be confused with Coady characterizes various forms of moralism and sketches their distorting influence on a realistic political morality. He seeks to restore the concept of ideals to an important place in philosophical discussion, and to give it a particular pertinence in the discussion of politics. He deals with the fashionable idea of "dirty hands," according to which good politics will necessarily involve some degree of moral taint or corruption. Finally, he examines the controversial issue of the role of lying and deception in politics. Along the way Coady offers illuminating discussion of historical and current political controversies. This lucid book will provoke and stimulate anyone interested in the interface of morality and politics.
