Propaganda is the executive arm of the invisible government. - Edward Bernays

No serious sociologist any longer believes that the voice of the people expresses any divine or specially wise and lofty idea. The voice of the people expresses the mind of the people, and that mind is made up for it by the group leaders in whom it believes and by those persons who understand the manipulation of public opinion. It is composed of inherited prejudices and symbols and clichés and verbal formulas supplied to them by the leaders.

The best defense against propaganda: more propaganda.

Domination to-day is not a product of armies or navies or wealth or policies. It is a domination based on the one hand upon accomplished unity, and on the other hand upon the fact that opposition is generally characterized by a high degree of disunity.
