“If a man cannot stand up in Charleston or Savannah or Richmond and say that he believes the right of every man to the enjoyment of life, liberty, and happiness to be self-evident; if he be tarred and feathered for saying it, or ridden upon a rail, or ducked in a horse-pond, or driven out of his pulpit or professorial chair, or shot down in his office, or waited upon by a committee who cannot be answerable for the chivalric impatience of their fellow-citizens — Mr. Douglas says it is a proof that his political principles are ruinous and fatal; which is simply the argument of a highway robber to his victim whom he knocks on the head, that if he didn't carry so much money in his pocket he wouldn't be robbed.”

1960s, The American Promise (1965)
Context: This was the first nation in the history of the world to be founded with a purpose. The great phrases of that purpose still sound in every American heart, North and South: "All men are created equal" — "government by consent of the governed" — "give me liberty or give me death." Well, those are not just clever words, or those are not just empty theories. In their name Americans have fought and died for two centuries, and tonight around the world they stand there as guardians of our liberty, risking their lives. Those words are a promise to every citizen that he shall share in the dignity of man. This dignity cannot be found in a man's possessions; it cannot be found in his power, or in his position. It really rests on his right to be treated as a man equal in opportunity to all others. It says that he shall share in freedom, he shall choose his leaders, educate his children, and provide for his family according to his ability and his merits as a human being.

God and the State (1871; publ. 1882)
Context: A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause. If we seek the liberation of the people by means of a lie, we will surely grow confused, go astray, and lose sight of our objective, and if we have any influence at all on the people we will lead them astray as well — in other words, we will be acting in the spirit of reaction and to its benefit.
