It is often an interesting proposition when lectures and other recordings meant for limited consumption are published for a broader audience. In this case, it is a mixed bag, but it tends towards the disappointing. There are flashes of insight towards practice, the problems of philosophy, and politics. Mostly, these lectures land squarely in the area of grand theory, with much conceptual discussion but not enough payoff for politics and human society.
Mixed in with the exegesis of Kant's moral philosophy, Adorno dashes in here and there a brilliant criticism and refutation of Stalinism. Similarly, he laid bare the idea that the individual should defer gratification for the society, as the payoff never comes. At the same time, Adorno reminds us, as his audience, that he is equally not a fan or an apologist for the late capitalist West under the sway of what he called the culture industry.
However, these points were too few and far between. The argument that C Wright Mills levied against Talcott Parsons in the Sociological Imagination proves all too applicable here too. As Mills pointed out, the cause of grand theory is their choice of a level of thinking so general that they cannot logically get down to observation. Like his contemporary, Parsons, this is Adorno in a nutshell. He never, as a grand theorist, gets down from the higher generalities to problems in their historical and structural contexts. In fact, as a prototypical grand theorist, Adorno has set forth a realm of concepts from which are excluded many structural features of human society, features long and accurately recognized as fundamental to its understanding.
Adorno seems to think—and this is implicit in his logic—that if he elevates and sores up high enough to the level of thought subsuming politics and society, he can then swoop back down and reemerge with clarity and the correct engagement. This is the Hegelian in him. In this, as a grand theorist, he is mistaken. Soaring up to the clouds, he loses touch with all of the detail. The best ways to truly engage with the political is to never disengage with it in the first place.
