This book brings together essays on modernity, social integration, social differentiation and social exclusion by Lockwood, Mouzelis and other eminent social theorists. At the same time it addresses critical issues facing Western democracies, such as social exclusion, the underclass, unemployment, new inequalities, globalization and the new competitive environment. Its novelty lies in the imaginative way it uses social theory to critique old, and suggest new, policies and political practices.
