This chapter explains the concept of reasonable multiculturalism. Building on the Rawlsian notion of reasonableness, and on Kymlicka’s formulation of multiculturalism, the mechanisms for reconciliation between liberalism and multiculturalism are outlined. What are the boundaries of multiculturalism within the framework of liberal democracy? What are the boundaries of state interference in the business of minority cultures whose norms and practices are at odd with liberal democracy? Reasonability assumes acceptance of the underpinning shared principles. Cultures that do not adhere to these principles are perceived as less reasonable. The extent of reasonability varies. But lacking reasonability does not immediately entail that the liberal majority should intervene in the business of the subcultures. Interference is warranted to restore justice. The chapter discusses the concept of mutual respect, distinguishing between two forms of cultural pluralism – ‘multination’ and ‘polyethnic’ states – and between two kinds of rights that a group might claim: the first involves the right of a group against its own members, the second involves the right of a group against the larger society. Furthermore, the nature of liberal tolerance and the mechanisms of deliberative democracy are explained, the latter instrumental for resolving disputes in a liberal democracy in a civil, non-violent way.
