Pós-Modernos, marxistas e a pobre ciência na modernidade

Based on the discussions about modernity, rationality and science, this article intends to broach  the debate, within the field of Social Sciences, among postmodernists and Marxists about the  validity of modern science and the criterion to determinate, or not, a new historical stage. To  situate this debate, we sought an analysis of the Michel Meffesoli’s postmodern thought and the  Marxist critique of Ellen Wood Meiksins. As a result, this article intends to clarify key points of  the theoretical debate and present a critical analysis about the validity, and the problems, of  Marxist and post-modern’s approaches.
