David Miller argues that national identity is indispensable for the successful functioning of a liberal democracy. National identity makes important contributions to liberal democratic institutions, including creating incentives for the fulfilment of civic duties, facilitating deliberative democracy, and consolidating representative democracy. Thus, a shared identity is indispensable for liberal democracy and grounds a good claim for self-determination. Because Miller’s arguments appeal to the instrumental values of a national culture, I call his argument ‘instrumental value’ arguments. In this paper, I examine the instrumental value arguments and show that they fail to justify a group’s right to self-determination.
