“No, liberty is not made for us: we are too ignorant, too vain, too presumptuous, too cowardly, too vile, too corrupt, too attached to rest and to pleasure, too much slaves to fortune to ever know the true price of liberty. We boast of being free! To show how much we have become slaves, it is enough just to cast a glance on the capital and examine the morals of its inhabitants.”

As quoted in "Stray Questions for: David Eagleman" by Blake Wilson in The New York Times (10 July 2009) http://artsbeat.blogs.nytimes.com/2009/07/10/stray-questions-for-david-eagleman/
Context: Our ignorance of the cosmos is too vast to commit to atheism, and yet we know too much to commit to a particular religion. A third position, agnosticism, is often an uninteresting stance in which a person simply questions whether his traditional religious story (say, a man with a beard on a cloud) is true or not true. But with Possibilianism I’m hoping to define a new position — one that emphasizes the exploration of new, unconsidered possibilities. Possibilianism is comfortable holding multiple ideas in mind; it is not interested in committing to any particular story.

Variant: Corruption often exists because there are too many market forces, not too few.

Far too many important decisions are made for 36 hours' publicity.

Über den Umgang mit Menschen (1788)
Context: Do not be too much a slave of others' opinions of you! Be self-sufficient! Why, in the end, does the opinion of the whole world trouble you, if you do what you should?

Innkeeper's wife
Source: A Child is Born (1942)
Context: God pity us indeed, for we are human,
And do not always see
The vision when it comes, the shining change,
Or, if we see it, do not follow it,
Because it is too hard, too strange, too new,
Too unbelievable, too difficult,
Warring too much with common, easy ways,
And now I know this, standing in this light,
Who have been half alive these many years,
Brooding on my own sorrow, my own pain,
Saying "I am a barren bough. Expect
Nor fruit nor blossom from a barren bough."

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.
