Political participation is falling and citizen alienation and cynicism are increasing. A growing number of philosophers and political practitioners have advocated for a more deliberative form of democracy in response to evidence of this decline in the traditional mechanisms of democracy. This volume brings together leading scholars in the US and Europe who for the first time represent the full panorama of research aspects and methods applicable to deliberative democracy as a means of political participation. The topics they investigate include general political talk, dialogue groups, jury deliberations, citizen deliberation, parliamentary discussion and public policy impacts. Four of the leading philosopher advocates of deliberative democracy then contribute their commentaries on this groundbreaking empirical research and the significant questions it raises regarding the conception and practice of deliberative democracy.
