“Constructing a social system that tends to those who agree with it is a piece of cake compared to constructing one that makes those who disagree with it want to obey its principles.”

Essay on Creativity in Science and Engineering

Political questionnaire response (1952)
Context: The other threat to the security of our tradition, I believe, lies at home. It is the current fear of radical ideas and of people who propound them. I do not agree with the extremists of either the left or the right, but I think they should be allowed to speak and to publish, both because they themselves have, and ought to have, rights, and once their rights are gone, the rights of the rest of us are hardly safe. Extremists typically want to squash not only those who disagree with them diametrically, but those who disagree with them at all. It seems to me that in every country where extremists of the left have gotten sufficiently in the saddle to squash the extremists of the right, they have ridden on to squash the center or terrorize it also. And the same goes for extremists of the right. I do not want that to happen in our country.

1963, Civil Rights Address
Context: The fires of frustration and discord are burning in every city, North and South, where legal remedies are not at hand. Redress is sought in the streets, in demonstrations, parades, and protests which create tensions and threaten violence and threaten lives. We face, therefore, a moral crisis as a country and as a people. It cannot be met by repressive police action. It cannot be left to increased demonstrations in the streets. It cannot be quieted by token moves or talk. It is a time to act in the Congress, in your State and local legislative body and, above all, in all of our daily lives. It is not enough to pin the blame on others, to say this is a problem of one section of the country or another, or deplore the fact that we face. A great change is at hand, and our task, our obligation, is to make that revolution, that change, peaceful and constructive for all. Those who do nothing are inviting shame as well as violence. Those who act boldly are recognizing right as well as reality.

Context: "You fought for the knife?"
"Yes, but — "
"Then you're a warrior. That's what you are. Argue with anything else, but don't argue with your own nature."
Will knew that the man was speaking the truth. But it wasn't a welcome truth. It was heavy and painful. The man seemed to know that, because he let Will bow his head before he spoke again.
"There are two great powers," the man said, "and they've been fighting since time began. Every advance in human life, every scrap of knowledge and wisdom and decency we have has been torn by one side from the teeth of the other. Every little increase in human freedom has been fought over ferociously between those who want us to know more and be wiser and stronger, and those who want us to obey and be humble and submit."
"And now those two powers are lining up for battle. And each of them wants that knife of yours more than anything else. You have to choose, boy. We've been guided here, both of us — you with the knife, and me to tell you about it."
