Cosmopolitan or nationalist? Why should we choose? It is time to redefine the meaning of origin and identity and stop mixing them. We are definitely unique, and the idea of origin is personal and the result of our identity.

Sarah is a French, Costa Rican and Tunisian national studying Politics and International Relations at the University of Cambridge, and is keen to complete her studies in International Law.

Sarah has a marked taste for current political debates about topics such as globalisation, climate change, cultural dialogue, security and peace building. Today, her interesting talk will focus on the "false debate" between respecting our own origins and traditions versus being free and cosmopolitan.
