The contributions to this anthology address and refine the still emerging theoretical debates about multiculturalism, nationalism and immigration. They focus especially on multiculturalism and nationalism as factual consequences of, and normative responses to, immigration. The unifying theme of the articles thus concerns the (lack of) normative significance of culture, both in arguments about how immigration and the resulting diversity should be handled, and as the object of political claims more generally. The contributions share a heightened and admirable sensitivity to the complexities of these issues. While most contributors believe that some form of multiculturalism follows from acceptance of liberal egalitarian principles, all qualify or question general models of multiculturalism and emphasize the mutuality of obligations. Collectively, the authors show simple discussions of multiculturalism and nationalism to be implausible, while providing a range of examples showing how a theoretically more satisfactory kind of discussion of multiculturalism and nationalism might proceed. The anthology also offers a tidy, introductory overview of the field.
