"A really efficient totalitarian state would be one in which the all-powerful
executive of political bosses and their army of managers control a population of
slaves who do not have to be coerced, because they love their servitude. To make
them love it is the task assigned, in present-day totalitarian states, to
ministries of propaganda, newspaper editors and schoolteachers.... The greatest
triumphs of propaganda have been accomplished, not by doing something, but by
refraining from doing. Great is truth, but still greater, from a practical point
of view, is silence about truth."
Aldous Huxley
