Context: If those in charge of our society — politicians, corporate executives, and owners of press and television — can dominate our ideas, they will be secure in their power. They will not need soldiers patrolling the streets. We will control ourselves.
"The Intellectual in America" (1955), from A Sad Heart at the Supermarket (1962)

“It's our duty to honor the dead by bringing democracy to this country.”
As quoted in "Reds parade coffins as govt accuses "terrorists"" in Bangkok Post (12 April 2010) http://www.bangkokpost.com/news/local/174496/reds-parade-coffins-as-govt-says-armed-men-among-protesters
“To have no food for our heads no food for our hearts, no food for our activity, is that nothing?”
Cassandra (1860)
Context: To have no food for our heads no food for our hearts, no food for our activity, is that nothing? If we have no food for the body, how do we cry out, how all the world hears of it, how all the newspapers talk of it, with a paragraph headed in great capital letters, DEATH FROM STARVATION! But suppose one were to put a paragraph in the Times, Death of Thought from Starvation, or Death of Moral Activity from Starvation, how people would stare, how they would laugh and wonder! One would think we had no heads nor hearts, by the total indifference of the public towards them. Our bodies are the only things of any consequence.

The Enemies of Reason (August 2007)
Variant: We should be open-minded, but not so open-minded that our brain falls out.
