Soviet Methods in the Anti Industry

Today I was  considering all sorts of things in a vague sort of way when the words of a famous novelist wandered through my mind.
They have an unarguable belief in the righteousness of their cause and the inevitability of that cause coming to fruition. They will listen to no argument against that cause. They consider all methods lawful that will further that cause. The use of lies and propoganda is necessary and correct to ensure that other people accept the imposition of that cause.
The words are from memory and may not as Eric Morcambe might said ' be nessessarily in the right order'  but are fairly accurate in their meaning. Who was he writing about? It was the attempted Sovietisation of Germany after the war but the words were learned well by the New Righteous to seek to regulate our lives by an increasing amount every day that passes.
