Nobel Prize Winner Doris Lessing:

WHILE we have seen the apparent death of Communism, ways of thinking that were either born under Communism or strengthened by Communism still govern our lives. Not all of them are as immediately evident as a legacy of Communism as political correctness.
The first point: language. It is not a new thought that Communism debased language and, with language, thought. There is a Communist jargon recognizable after a single sentence. Few people in Europe have not joked in their time about “concrete steps,” “contradictions,” “the interpenetration of opposites,” and the rest.
The first time I saw that mind-deadening slogans had the power to take wing and fly far from their origins was in the 1950s when I read an article in The Times of London and saw them in use. “The demo last Saturday was irrefutable proof that the concrete situation…” Words confined to the left as corralled animals had passed into general use and, with them, ideas. One might read whole articles in the conservative and liberal press that were Marxist, but the writers did not know it. But there is an aspect of this heritage that is much harder to see.
Even five, six years ago, Izvestia, Pravda and a thousand other Communist papers were written in a language that seemed designed to fill up as much space as possible without actually saying anything. Because, of course, it was dangerous to take up positions that might have to be defended. Now all these newspapers have rediscovered the use of language. But the heritage of dead and empty language these days is to be found in academia, and particularly in some areas of sociology and psychology.
