“FREEDOM, the realization of freedom: who can deny that this is what today heads the agenda of history?”

Variant: Those who deny freedom to others deserve it not for themselves, and, under a just God cannot retain it.

Source: Infinite in All Directions (1988), Ch. 1 : In Praise of Diversity
Context: Science and religion are two human enterprises sharing many features. They share these features also with other enterprises such as art, literature and music. The most salient features of all these enterprises are discipline and diversity. Discipline to submerge the individual fantasy in a greater whole. Diversity to give scope to the infinite variety of human souls and temperaments. Without discipline there can be no greatness. Without diversity there can be no freedom. Greatness for the enterprise, freedom for the individual — these are the two themes, contrasting but not incompatible, that make up the history of science and the history of religion.

The Ballot or the Bullet (1964), Speech in Detroit, Michigan (12 April 1964)
Context: The government has failed us; you can’t deny that. Anytime you live in the twentieth century, 1964, and you’re walking around here singing “We Shall Overcome,” the government has failed us. This is part of what’s wrong with you -- you do too much singing. Today it’s time to stop singing and start swinging. You can’t sing up on freedom, but you can swing up on some freedom. Cassius Clay can sing, but singing didn’t help him to become the heavyweight champion of the world; swinging helped him become the heavyweight champion.

The Path To Power (1995)

Address at the National Archives dedicating a shrine for the Declaration of Independence, the Constitution, and the Bill of Rights (15 December 1952) https://trumanlibrary.org/calendar/viewpapers.php?pid=2102
Context: Of course, there are dangers in religious freedom and freedom of opinion. But to deny these rights is worse than dangerous, it is absolutely fatal to liberty. The external threat to liberty should not drive us into suppressing liberty at home. Those who want the Government to regulate matters of the mind and spirit are like men who are so afraid of being murdered that they commit suicide to avoid assassination.
All freedom-loving nations, not the United States alone, are facing a stern challenge from the Communist tyranny. In the circumstances, alarm is justified. The man who isn't alarmed simply doesn't understand the situation — or he is crazy. But alarm is one thing, and hysteria is another. Hysteria impels people to destroy the very thing they are struggling to preserve.
Invasion and conquest by Communist armies would be a horror beyond our capacity to imagine. But invasion and conquest by Communist ideas of right and wrong would be just as bad.
For us to embrace the methods and morals of communism in order to defeat Communist aggression would be a moral disaster worse than any physical catastrophe. If that should come to pass, then the Constitution and the Declaration would be utterly dead and what we are doing today would be the gloomiest burial in the history of the world.

1930s, Fireside Chat in the night before signing the Fair Labor Standards (1938)
Context: And I am concerned about the attitude of a candidate or his sponsors with respect to the rights of American citizens to assemble peaceably and to express publicly their views and opinions on important social and economic issues. There can be no constitutional democracy in any community which denies to the individual his freedom to speak and worship as he wishes. The American people will not be deceived by anyone who attempts to suppress individual liberty under the pretense of patriotism. This being a free country with freedom of expression — especially with freedom of the press — there will be a lot of mean blows struck between now and Election Day. By "blows" I mean misrepresentation, personal attack and appeals to prejudice. It would be a lot better, of course, if campaigns everywhere could be waged with arguments instead of blows.

Variant: Until you 've lost your reputation, you never realize what a burden it was or what freedom really is.
