'Ideology is a specious way or relating to the world. It offers human beings the illusion of an identity, of dignity, and of morality while making it easier for them to part with them. As the repository of something suprapersonal and objective, it enables people to deceive their conscience and conceal their true position and their inglorious modus vivendi, both from the world and from themselves. It is a very pragmatic but, at the same time, an apparently dignified way of legitimizing what is above, below, and on either side. It is directed toward people and toward God. It is veil behind which human beings can hide their own fallen existence, their trivialization, and their adaptation to the status quo. It is an excuse that everyone can use, from the greengrocer, who conceals his fear of losing his job behind an alleged interest in the unification of the workers of the world, to the highest functionary, whose interest in staying in power can be cloaked in phrases about service top the working class. The primary excusatory function of ideology, therefore, is to provide people, both as victims and pillars of the post-totalitarian system, with the illusion that the system is in harmony with the human order and the order of the universe.'
Vaclav Havel, 'The Power of the Powerless' in Open Letters, p.133.
