For Dialectic of Enlightenment discussion, we should be familiar with Homer’s Odyssey And yes, there is a huge problem with regard to class politics in Adorno and Horkheimer’s take on the classics, but think of the polytheism as the religion of a distinct mode of production and Odysseus’ transactional view of sacrifice as the new view of the market economy.
I also think it might be good to have a good sense of the major parameters of the Enlightenment and perhaps the European 18th Century in general, but for the purposes of our discussion, familiarity with Cartesian method, Jean Jacques Rousseau, the Marquis de Sade and the major French Revolution.
