The purpose of this article is to offer an approach to Michael Löwy's Latin American Marxism. In my hypothesis, Löwy’s Marxism is marked by a radical critique of Eurocentrism and lies in permanent dialogue with the “warm currents” of European Marxism. Applying the theoretical approach of the sociology of revolutionary intellectuals and through a qualitative methodology of hermeneutical nature, we will analyze two central dialogic knots in Löwy's work, expressed in the affinities between León Trotsky and Ernesto Guevara, such as those of José Carlos Mariátegui and Walter Benjamin.
