Optimism (1903)
Context: The idea of brotherhood redawns upon the world with a broader significance than the narrow association of members in a sect or creed; and thinkers of great soul like Lessing challenge the world to say which is more godlike, the hatred and tooth-and-nail grapple of conflicting religions, or sweet accord and mutual helpfulness. Ancient prejudice of man against his brother-man wavers and retreats before the radiance of a more generous sentiment, which will not sacrifice men to forms, or rob them of the comfort and strength they find in their own beliefs. The heresy of one age becomes the orthodoxy of the next. Mere tolerance has given place to a sentiment of brotherhood between sincere men of all denominations.

Summation for the Prosecution, July 26, 1946
Quotes from the Nuremberg Trials (1945-1946)
Context: These men saw no evil, spoke none, and none was uttered in their presence. This claim might sound very plausible if made by one defendant. But when we put all their stories together, the impression which emerges of the Third Reich, which was to last a thousand years, is ludicrous. If we combine only the stories of the front bench, this is the ridiculous composite picture of Hitler's Government that emerges. It was composed of:
A No. 2 man who knew nothing of the excesses of the Gestapo which he created, and never suspected the Jewish extermination programme although he was the signer of over a score of decrees which instituted the persecution of that race;
A No. 3 man who was merely an innocent middleman transmitting Hitler's orders without even reading them, like a postman or delivery boy;
A Foreign Minister who knew little of foreign affairs and nothing of foreign policy;
A Field-Marshal who issued orders to the armed forces but had no idea of the results they would have in practice …
… This may seem like a fantastic exaggeration, but this is what you would actually be obliged to conclude if you were to acquit these defendants.
They do protest too much. They deny knowing what was common knowledge. They deny knowing plans and programmes that were as public as Mein Kampf and the Party programme. They deny even knowing the contents of documents which they received and acted upon. … The defendants have been unanimous, when pressed, in shifting the blame on other men, sometimes on one and sometimes on another. But the names they have repeatedly picked are Hitler, Himmler, Heydrich, Goebbels, and Bormann. All of these are dead or missing. No matter how hard we have pressed the defendants on the stand, they have never pointed the finger at a living man as guilty. It is a temptation to ponder the wondrous workings of a fate which has left only the guilty dead and only the innocent alive. It is almost too remarkable.
The chief villain on whom blame is placed — some of the defendants vie with each other in producing appropriate epithets — is Hitler. He is the man at whom nearly every defendant has pointed an accusing finger.
I shall not dissent from this consensus, nor do I deny that all these dead and missing men shared the guilt. In crimes so reprehensible that degrees of guilt have lost their significance they may have played the most evil parts. But their guilt cannot exculpate the defendants. Hitler did not carry all responsibility to the grave with him. All the guilt is not wrapped in Himmler's shroud. It was these dead men whom these living chose to be their partners in this great conspiratorial brotherhood, and the crimes that they did together they must pay for one by one.

The Great Dictator (1940), The Barber's speech
Context: I'm sorry, but I don't want to be an emperor. That's not my business. I don't want to rule or conquer anyone. I should like to help everyone, if possible, Jew, gentile, black man, white. We all want to help one another. Human beings are like that. We want to live by each other's happiness — not by each other's misery. We don't want to hate and despise one another.
In this world there is room for everyone. And the good earth is rich and can provide for everyone. The way of life can be free and beautiful, but we have lost the way. Greed has poisoned men's souls, has barricaded the world with hate, has goose-stepped us into misery and bloodshed. We have developed speed, but we have shut ourselves in. Machinery that gives abundance has left us in want. Our knowledge has made us cynical. Our cleverness, hard and unkind. We think too much and feel too little. More than machinery we need humanity. More than cleverness we need kindness and gentleness. Without these qualities, life will be violent and all will be lost.
The aeroplane and the radio have brought us closer together. The very nature of these inventions cries out for the goodness in men, cries out for universal brotherhood, for the unity of us all. Even now my voice is reaching millions throughout the world — millions of despairing men, women and little children — victims of a system that makes men torture and imprison innocent people. To those who can hear me, I say — do not despair. The misery that is now upon us is but the passing of greed — the bitterness of men who fear the way of human progress. The hate of men will pass, and dictators die, and the power they took from the people will return to the people and so long as men die, liberty will never perish.
Soldiers! Don't give yourselves to brutes — men who despise you — enslave you — who regiment your lives — tell you what to do — what to think or what to feel! Who drill you, diet you, treat you like cattle, use you as cannon fodder. Don't give yourselves to these unnatural men — machine men with machine minds and machine hearts! You are not machines! You are not cattle! You are men! You have the love of humanity in your hearts. You don't hate! Only the unloved hate — the unloved and the unnatural!
Soldiers! Don't fight for slavery! Fight for liberty! In the 17th Chapter of St. Luke it is written: "the Kingdom of God is within man" — not one man nor a group of men, but in all men! In you! You, the people have the power — the power to create machines. The power to create happiness! You, the people, have the power to make this life free and beautiful, to make this life a wonderful adventure.
Then, in the name of democracy, let us use that power! Let us all unite! Let us fight for a new world, a decent world that will give men a chance to work, that will give youth the future and old age a security. By the promise of these things, brutes have risen to power, but they lie! They do not fulfill their promise; they never will. Dictators free themselves, but they enslave the people! Now, let us fight to fulfill that promise! Let us fight to free the world, to do away with national barriers, to do away with greed, with hate and intolerance. Let us fight for a world of reason, a world where science and progress will lead to all men's happiness.
Soldiers! In the name of democracy, let us all unite!
[Cheers]
Hannah, can you hear me? Wherever you are, look up, Hannah. The clouds are lifting. The sun is breaking through. We are coming out of the darkness into the light. We are coming into a new world, a kindlier world, where men will rise above their hate, their greed and brutality. Look up, Hannah. The soul of man has been given wings, and at last he is beginning to fly. He is flying into the rainbow — into the light of hope, into the future, the glorious future that belongs to you, to me and to all of us. Look up, Hannah. Look up.
