"Jargon of Authenticity" takes a critical approach to language but is ideologically critical in the strict sense, examining a false consciousness as it is revealed in a very specific modern German vocabulary. Initially, the language form is analyzed for its expressive content, which is then derived from the falsehood of the philosophy that shapes that vocabulary. Thus, it concerns a piece of executed dialectics between form and content. The transformation of that false consciousness has immediate, impactful practical significance.
