The idea that diverse cultural and ethnic groups should co-exist within a country and that assimilation should not be forced upon immigrant groups - "multiculturalism" - was orthodoxy 20 years ago. Today it's coming under pressure. In this introduction to the political theory of multiculturalism, Andrew Shorten surveys the leading theories of multiculturalism, the critiques that have been levelled against the idea, and the debates surrounding cohesion, integration and diversity. He then goes on to demonstrate how multicultural political theory can be renewed, arguing that a single, monolithic vision of multiculturalism must be replaced by a multiculturalism made up of different strands, responding to distinctive but interrelated issues, and inspired by real-world policy debates about how political communities should respond to differences of religion, language and nationality. After tracing the influence of earlier multicultural ideas on these debates, Shorten reveals some new and surprising possibilities for mutual learning. Containing an up-to-date overview of multicultural political theory and its various offshoots, this book is essential reading for students and scholars interested in the politics of cultural, religious, linguistic and national diversity.
