may perform both of these functions at the same time. Ideology, in Mannheim's terms, is both "ideology" and "utopia."
Sixth, all ideologies serve as instruments for the manipulation and control of the people. A country's leaders are always in a position to dupe the masses, particularly in the light of contemporary advances in technologies of communication. The only questions are the regularity, extent, and intensity with which popular manipulation and control are exercised.
Finally, ideologies perform--or should perform--a self-maintenance function. A viable ideology must keep up with changing times and conditions; it must adapt its tenets and principles to the needs and requirements of the times. Ideologies that engage in this process of continuous adaptation are likely to thrive and flourish; ideologies that do not are likely to fall on hard times.
