“People said it because other people said it. They did not know why it was being said and heard everywhere. They did not give or ask for reasons. 'Reason,' Dr. Pritchett had told them, 'is the most naive of all superstitions.' 'The source of public opinion?' said Claude Slagenhop in a public radio speech. 'There is no source of public opinion. It is spontaneously general. It is a reflex of the collective instinct of the collective mind.”

“Promote, then, as an object of primary importance, institutions for the general diffusion of knowledge. In proportion as the structure of a government gives force to public opinion, it is essential that public opinion should be enlightened.”

“A woman who does not know herself has no choice other than to live with other people’s evaluations. But no one can adapt perfectly to public opinion. And herein lies the source of their destruction.”

“But the public did not know the truth about what happened to the people in the trucks; they believed the stories from the government, who said that these people, known as Untermensch (non-people or ‘lower people’), were simply moved to open spaces in the east and settled on farms, away from Germany, so as not to ‘contaminate’ the German race. This is an example of people not wishing to know the facts behind the rumours in which were whispered between trusted friends. The general belief was that the rumours were rubbish anyway, for how could a civilized country do such things? Our leaders would never allow anything bad to happen to these people; after all, we were not barbarians! And so nothing was said, or done, and the public developed a collective blindness to the truth.”

“Public opinion is the worst of all opinions.”

“The key obstacle to reforming aid is public opinion.. Public opinion drives them into the "I care" photo opportunities that dominate aid.”
