…the musical accompaniment with which the SS liked to drown out the screams of its victims

If negative dialectics calls for the self-reflection of thinking, the tangible implication is that if thinking is to be true—if it is to be true today, in any case—it must also be thinking against itself. If thought is not measured by the extremity that eludes the concept, it is from the outset in the nature of the musical accompaniment with which the SS liked to drown out the screams of its victims.

…to extinguish it in the very negation of negation that will not become a positing

It is a critique of the fact that critique itself, contrary to its own tendency, must remain within the medium of the concept. It destroys the claim of identity by testing and honoring it; therefore, it can reach no farther than that claim. The claim is a magic circle that stamps critique with the appearance of absolute knowledge. It is up to the self-reflection of critique to extinguish that claim, to extinguish it in the very negation of negation that will not become a positing. (406)

Represented in the inmost cell of thought is that which is unlike thought

Represented in the inmost cell of thought is that which is unlike thought. The smallest intra-mundane traits would be of relevance to the absolute, for the micrological view cracks the shells of what, measured by the subsuming cover concept, is helplessly isolated and explodes its identity, the delusion that it is but a specimen. There is solidarity between such thinking and metaphysics at the time of its fall. (406)
