In this century there has been a deep concern about the dangers of nationalism. Many of those who have expressed such concerns have been liberals. Yet, ironically, in the last decade there has been a resurgence of interest in the idea of nationalism from within liberal thought- thus giving rise to the compound term ‘liberal nationalism’. Having situated liberal nationalism in a broader historical context, this paper critically reviews the arguments of liberal nationalism in the work of Neil MacCormick, David Miller and Yael Tamir. It concludes by drawing a distinction between the pragmatic and ethical significance of nationalism. This distinction neither entails a denial of the role of nationalism nor a defense of liberalism. It attempts to sever the connection between nationalism and ethics. Nationalism may be inevitable for the present, but it is not a virtue to be promoted.
