Ideology is a ubiquitous, continuously innovating dimension of human experience, but its character and impact are notoriously difficult to pinpoint within political and social life. Political Ideology in Parties, Policy, and Civil Society demonstrates that the reach and significance of political ideology can be most effectively understood by employing a multidisciplinary approach. Offering analyses that are simultaneously empirical and interpretive - in fields as diverse as development assistance policy and game theory - the contributors to this volume reveal ideology's penetration in varied spheres, including government activity, party competition, agricultural and working-class communities, and academic life.
