Abstract
The point of departure of this study is Walter Benjamin’s last text, “Theses on the Philosophy of History.” Benjamin appeals to the significance of theology for historical materialism in order to overcome one of the decisive reasons why Marx’s unique theoretical project, in its positivistic interpretations, was not understood with the necessary radicality and had been in danger of losing its explanatory power and revolutionary impulse. The necessity of looking back to the past constitutes the basic theme of the study, and it is analyzed at the epistemological, ontological and political levels. The view backwards is also necessary because the past shows how all its atrocities, which we think have been overcome, may at any time return in a way which we are unable to imagine.
