Liberalism and nationalism are in many ways contradictory positions. The ideals of open borders, free movement of people, goods and services, cosmopolitanism and internationalism that are associated with liberalism, can be contrasted with nationalist ideals such as tradition, home and to guard the nation from outside influence.

In this conversation with Gustaf Arrhenius, professor of moral and political philosophy and director of the Institute for Futures Studies, David Miller explains why.
