Simply put: "The party told you to reject the evidence of your eyes and ears. It was their final, most essential command." - 1984, Orwell
And from the opposite side of the political spectrum, similar sentiment:
"Have you ever wondered, perhaps, why opinions which the majority of people quite naturally hold are, if anyone dares express them publicly, denounced as ’controversial, ‘extremist’, ‘explosive’, ‘disgraceful’, and overwhelmed with a violence and venom quite unknown to debate on mere political issues? It is because the whole power of the aggressor depends upon preventing people from seeing what is happening and from saying what they see." - Enoch Powell
