Vaclav Havel, the Power of the Powerless (1978)

As the interpretation of reality by the power structure, ideology is always subordinated ultimately to the interests of the structure. Therefore, it has a natural tendency to disengage itself from reality, to create a world of appearances, to become ritual. In societies where there is public competition for power and therefore public control of that power, there also exists quite naturally public control of the way that power legitimates itself ideologically. Consequently, in such conditions there are always certain correctives that effectively prevent ideology from abandoning reality altogether. Under totalitarianism, however, these correctives disappear, and thus there is nothing to prevent ideology from becoming more and more removed from reality, gradually turning into what it has already become in the post-totalitarian system: a world of appearances, a mere ritual, a formalized language deprived of semantic contact with reality and transformed into a system of ritual signs that replace reality with pseudo-reality.
