Emir Sader majored in Philosophy and obtained his doctor's degree in Political Sciences at São Paulo University with a thesis entitled "Hegemony crisis and its ideology: theories of the Brazilian State during the military regime". As a professor, he taught in many national and international institutions and maintained an intense collaboration with Latin American countries. Since 2000, he has been teaching at the State University of Rio de Janeiro in the Graduate Program in Sociology and coordinating the Laboratory of Public Policies of the university. Emir Sader also coordinates the research group Knowledge, Autonomy and Participation, which researches Public Policies and Education. In 2004, he won the Jabuti Award, granted by the Brazilian Book Chamber. Among the author's recent books are Perspectivas [Prospects] (Record, 2005) and Crisis hegemónicas en tiempos imperiales [Hegemonic crises in imperial times] (Center for Investigation and Development, Havana, 2004). In this interview, which reveals the author's keen sense of these movements and of the geopolitical context of Latin America (reclaiming the liberating perspective present in the region's historical background), Emir Sader speaks of the weakening of the theory of neoliberalism, the roles of social movements in resisting to this model, and the aggravation of religious fundamentalism.
