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.

Introduction to Absurd Drama (1965)
Context: The Theatre of the Absurd attacks the comfortable certainties of religious or political orthodoxy. It aims to shock its audience out of complacency, to bring it face to face with the harsh facts of the human situation as these writers see it. But the challenge behind this message is anything but one of despair. It is a challenge to accept the human condition as it is, in all its mystery and absurdity, and to bear it with dignity, nobly, responsibly; precisely because there are no easy solutions to the mysteries of existence, because ultimately man is alone in a meaningless world. The shedding of easy solutions, of comforting illusions, may be painful, but it leaves behind it a sense of freedom and relief. And that is why, in the last resort, the Theatre of the Absurd does not provoke tears of despair but the laughter of liberation.
