After providing a brief overview of Adorno’s life, Schweppenhäuser turns to the theorist’s core philosophical concepts, including post-Kantian critique, determinate negation, and the primacy of the object, as well as his view of the Enlightenment as a code for world domination, his diagnosis of modern mass culture as a program of social control, and his understanding of modernist aesthetics as a challenge to conceive an alternative politics. Along the way, Schweppenhäuser illuminates the works widely considered Adorno’s most important achievements: Minima Moralia, Dialectic of Enlightenment (co-authored with Horkheimer), and Negative Dialectics. Adorno wrote much of the first two of these during his years in California (1938–49), where he lived near Arnold Schoenberg and Thomas Mann, whom he assisted with the musical aesthetics at the center of Mann’s novel Doctor Faustus.
