In recent years there has been a renewal of interest in new modes of theorizing borders and margins, the impact of information technologies on the notion of borders as barriers, and the contribution of “marginal” groups to meditation on a variety of themes and concepts associated with the evolution of political thought in diverse contexts, such as statehood, sovereignty, citizenship, and global justice. This session seeks to accommodate a variety of approaches to the phenomenon of globalization and the role of borders and margins, including historical, philosophical, legal, normative, feminist, post-colonial, experimental trends. The session encourages presentations in all fields of political theory and political philosophy, including the history of political thought, normative political theory, analytical political philosophy, political ideologies, post-structuralism and other post-foundational methods of political theorizing, democratic theory, applied ethics, international political theory, and comparative political thought. Papers exploring various facets of the Congress theme: the impact of borders and margins on the development of contemporary political and social theory with a focus on e.g. citizenship, immigration, the obligations of states to citizens and non-citizens, and the idea of territoriality as a key feature of the modern state, are particularly welcome.
