Power is in tearing human minds to pieces  and putting them together again in new shapes of your own choosing.
George Orwell
1984
"Fear has always been the most potent instrument of the authoritarian state. Fear promotes intolerant conformism and provokes abuse at anyone who steps out of Government’s line.
These are the authentic ingredients of a totalitarian society.  I regret to say there is another feature …the propaganda by which the Government is allowed to promote its own agenda”.
Lord Sumption
