"The passions could be mobilized for social change by anyone who knows how to manipulate them successfully. This had been the lesson of the Enlightenment and the French Revolution. The lesson of war, a lesson soon to be transferred to the advertising agencies of the 1920s, was that these passions could be liberated by the manipulation of public opinion and redirected into channels congenial to those who control public opinion... Everyone had to be involved in the subversion of morals, in other words, or at least everyone had to be perceived as being involved. Otherwise, the aberrant individual would be ostracized for antisocial behaviour...
...But pan-cultural liberation can only take place with the assistance of pan-cultural instruments of persuasion. It could only take place with the emergence of mass-media, and it was precisely those instruments - magazines with a national circulation, cinema, radio, television - which emerged during the course of Bernay's' long life. It was Bernays, taking his cue from this famous uncle [Freud], who write the book on how to manipulate the masses through those instruments.
...In order to re-engineer man, the "invisible governors" had to create a world populated by "mass man", rootless individuals cut off from ethnic and religious affiliation who relied on the opinion of what seemed to be everyone else as propagated by the mass media. The new authority which everyone followed in this regard was science. Science broke taboos; science gave rational permission whereas tradition proposed only irrational restraint. - E Michael Jones (Libido Dominandi: Sexual Liberation and Political Control, Chapter 10: Versailles, pg. 186)
