Heidegger and the "Dialectic of the Enlightenment"

I have been rereading the Dialectic of the Enlightenment in Edmund Jephcott's fairly new translation. In the course of working through it I have been struck as never before by certain similarities between this work and Heidegger's concerns in the 1950s. This, in turn, will connect in the future to certain reflections on Vattimo and Zabala's Hermeneutic Communism. I would like to take the time to note some of these similarities and the even more striking differences, in connection with Hegel and Marx, these aspects make apparent.
