This volume explores questions of modernity through critical engagements with the work of Anthony Giddens, focusing in particular on the relationships between his social theory and political sociology. Three substantive areas - reflexivity, environment and identity - are examined theoretically through the relationships between reflexivity and rationality, life politics and institutional power, and universalism and 'difference'. As well as specifically addressing Giddens' reconstruction of sociology, the contributors also explore a wide variety of critical issues currently occupying centre stage in social theory. These include questions about the character of contemporary societies, the periodisation of social change, the processes of change by which societies are constantly made and remade by people, the relationships between the 'social' and the 'natural', the formation and maintenance of identities and matters of epistemology and methodology in social science.
