Fim da luta de classes? A teoria das classes em poder político e classes sociais a partir de maio de 1968 e sua peculiaridade em relação à corrente Althusseriana

Departing from sociological interpretations inspired by May of 1968, this article attempts to revive the centrality of the theory of social classes for the understanding of the different social movements and collective organizations. To that end, it departs from the contributions of Nicos Poulantzas’s Political Power and Social Classes, attempting to determine its peculiarities, advances and limits en relation to the process of renovation of Marxism, in general, and the Althusserian current, in particular. The general thesis is that this work has a theory of social classes in a practical state, whose principle characteristic is the primacy of social practices in the delimitation of social classes
