This paper argues that the different ways of facing Hegel's system, as an impossible attempt to harmonize tradition and openness to novelty, respond to an underlying malaise: that provoked by the disturbing question of “the actuality of philosophy” after Hegel. That question insistently arises with respect to different paradigms of contemporary philosophy, and is found in critical theory, in analytical philosophy of action, in Žižek's materialism, and in Derrida's deconstructive reading. Adorno's interpretation introduces the tension between universal concepts and laws, transmitted by the cultural tradition, and particular elements that the subject of the action must always take into account. As a consequence, the subject must include what is not reducible to a concept, which enables the construction of a language of experience that transcends the identifying thinking of the concept and makes negative dialectics possible as a theory of action.
