In this paper, I will focus on the nature of the modernity from the perspective of a «logical» square. On the basis of its vectorial orientation, I will show the value of Guy Debord’s work, according to which, undeniably, there is a need to articulate two core issues of our time: «How does a multitude turn into a class?» (Benjamin’s question) and «How does the individual become a subject?» (Althusser’s question). It is precisely the nexus between these questions that allows (...) us to draw the line between the modernity and the postmodernity. (shrink)
