“Most of us stand poised at the edge of brilliance, haunted by the knowledge of our proximity, yet still demonstrably on the wrong side of the line, our dealings with reality undermined by a range of minor yet critical psychological flaws (a little too much optimism, an unprocessed rebelliousness, a fatal impatience or sentimentality). We are like an exquisite high-speed aircraft which for lack of a tiny part is left stranded beside the runway, rendered slower than a tractor or bicycle.”

Context: When we meet someone and fall in love, we have a sense that the whole universe is on our side. And yet if something goes wrong, there is nothing left! How is it possible for the beauty that was there only minutes before to vanish so quickly? Life moves very fast. It rushes from heaven to hell in a matter of seconds.

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.

Context: I have sought with some touches of detail to bring out the solidarity and historical continuity of the High Intelligentsia of England, who have built up the foundations of our thought in the two and a half centuries, since Locke, in his Essay Concerning Human Understanding, wrote the first modern English book. I relate below the amazing progeny of Sir George Villiers. But the lineage of the High Intelligentsia is hardly less interbred and spiritually inter-mixed. Let the Villiers Connection fascinate the monarch or the mob and rule, or seem to rule, passing events. There is also a pride of sentiment to claim spiritual kinship with the Locke Connection and that long English line, intellectually and humanly linked with one another, to which the names in my second section belong. If not the wisest, yet the most truthful of men. If not the most personable, yet the queerest and sweetest. If not the most practical, yet of the purest public conscience. If not of high artistic genius, yet the most solid and sincere accomplishment within many of the fields which are ranged by the human mind.

Context: Let us roll all our strength and all
Our sweetness up into one ball,
And tear our pleasures with rough strife
Thorough the iron gates of life:
Thus, though we cannot make our sun
Stand still, yet we will make him run.
