Orwell got the concepts from Marx and Engles. All of the breakdown of society in socialist states and ideologies are all outlined in Marx’s and Engles’ works. A culture of distrust is necessary in order to control the thoughts of the workers and protect them from the ever present threat of capitalist thought. It’ all in the “manual”.
In bourgeois society the past controls the present; in communist society, the present controls the past.Straight out of the Manifestos second chapter. The USSR put that into practice, as did everyone that followed them in that sick revolution into dystopia.
Also embodied in the Manifesto’s calls for the abolition of the family and of private property.
If you ask me which historical figure I would have aborted if I could, Karl Marx would probably be my pick.
