El proposito de este articulo es contribuir a la busqueda de enfoques teoricos, distintos a la ortodoxia, que permitan comprender la actual crisis sistemica que vive el mundo. Se plantea el pensamiento de Carlos Marx como alternativa, con base en que permite un enfoque complejo de la realidad social. Se lleva a cabo una historia sintetica de la formacion de este pensamiento y de su deuda teorica con Hegel y Feuerbach y la manera como Marx reelabora la herencia de sus maestros, para formar un metodo dialectico, historico y materialista. Se detallan, luego, las caracteristicas del metodo de Marx y la manera de identificarlas a lo largo de su obra,particularmente en El capital. Se agrega a lo anterior, en forma resumida, las visiones de algunos marxistas de la actualidad, para concluir que, dada la complejidad de la crisis actual, se requiere para su comprension de un enfoque que permita acercarse a esa complejidad y que el metodo de Carlos Marx es adecuado para ese proposito. ABSTRACT The purpose of this article is a contribution to the search for theoretical, rather than orthodox, approaches that allow an understanding of the current systemic crisis in the world. The article raises the thoughts of Carlos Marx as an alternative, with a base that allows for a more complex approach to social reality. The article carries out a synthetic history of the formation of this thought and its theoretical debt to Hegel and Feuerbach through which Marx re-elaborates the inheritance of his teachers to form a dialectical and historical materialist method. The above theories are listed along with the characteristics of Marx method and how to identify them throughout his work, particularly in Das Kapital (The capital). Added to the above, in summary form, are the visions of some contemporary Marxists, given the complexity of the current crisis, in order to amplify the comprehension of an approach to the complexity and method of Carl Marx to promote an explanation of its suitability toward that purpose.
