The document discusses dissent and artistic expression under Soviet leadership. It explains that while dissent was too dangerous under Stalin, people were more willing to express opinions after Khrushchev challenged Communist infallibility. However, political dissent was still rare. The document also notes that Brezhnev allowed art that reflected the views of the working class but did not tolerate "art for art's sake." Those who challenged the system through artistic or intellectual expression became known as dissidents.
