In his book "The Jargon of Authenticity," Theodor Adorno discusses what he considers to be a major fallacy with all of society: the way we talk. It is his opinion and observance that we speak in such a way as to bring others down while at the same time raising ourselves up. "The jargon -- objectively speaking, a system -- uses disorganization as its principle of organization, the breakdown of language into words in themselves." The jargon is a tool used by society in order to distinguish the few from the many, to distinguish "my" class from "your" class.
Adorno uses Language the same way Benjamin used cities. He demonstrates that language through "the jargon" is being manipulated to further the cause of capitalism. Adordo comes down on Existentialism, which is the notion that we create our own worlds through our choices. We choose a thing and thus it exists, it becomes real. Adorno felt this fell into the category of the subjective, and therefore the unrelieable. Adorno, like Horkhiemer, wanted a return to objective transcendent truth. This truth comes through a proper use of language. Adorno seems to agree with historical materialism in that he is calling for change, that nessisarily comes through revolution.
In order to become a better society, we need to overcome this basic problem of communication. We need to speak the Truth, not our own personal truth. We need to rid our discussions of the stereotypes, the advertisements, the put-downs, and especially the lies. In doing so, we will be able to discuss what is really important: the ideas. We will be able to open our minds and discover new ways of thinking, new ways of looking at the world, instead of trying to convince those around us that ours is the correct view.
