Terry Eagleton, a prominent current theoretician of ideology, claims in the introduction to his well-known book Ideology. An Introduction (1991) that no one has ever come with a single satisfactory definition of ideology and in this respect he will not be an exception either. Then, he lists seventeen different meanings of the term ideology used nowadays (that is, in the 1990s) in both public and academic discourse. Some of these meanings are actually contradictory, some are judgmental – negative and/or pejorative and other are neutral.
