The main point of this article is that the task of critical educators in the age of massive globalised immigration is to move beyond national essentialism and cultural purism. They have to transgress the restraints of methodological nationalism, omnipresent in the diverse aspects of education including the action of many educators. This implies that they should act as public, critical and transformative intellectuals seeking to politicize education especially vis-a-vis current xenophobic political discourses and media representations, which draw on hegemonic understandings of history and culture. As the immigration history reminds us, these anti-immigrant crusades are intensified during economic crises because of nationalist propaganda triggered by the political elites in their attempt to gain over their disillusioned voters. In the era of forced migration, strongly associated with the pressures of late capitalism, educators should be inspired by humanist, democratic ideals, as framed understandings of cultural translation and not as another Western canon in order to pursue coexistence and activate alliances through cultural and other differences. This seems to be an urgent task in Greece now. (Contains 10 footnotes.)
