But, Three:

"... My mother said I broke her heart...but it was my integrity that was important. Is thatso selfish? It sells for so little, but it's all we have left in this place. It is the very last inch of us...but within that inch we are free...."

"Happiness is the most insidious prison of all."

"I shall die here. Every last inch of me shall perish . Except one. An inch. It's small and it's fragile and it's the only thing in the world worth having. we must never lose it, or sell it, or give it away. We must never let them take it from us."

"Since mankind's dawn, a handful of oppressors have accepted the responsibility
over our lives that we should have accepted for ourselves. By doing so, they took our power. By doing nothing, we gave it away. We've seen where their way leads, through camps and wars, towards the slaughterhouse."

"Because while the truncheon may be used in lieu of conversation in lieu of conversation, words will always retain their power. Words offer the means to meaning, and for those who will listen, the enunciation of truth. And the truth is, there is something terribly wrong with this country, isn't there? Cruelty and injustice, intolerance and oppression. And where once you had the freedom to object, to think and speak as you saw fit, you now have censors and systems of surveillance coercing your conformity and soliciting your submission. How did this happen? Who's to blame? Well certainly there are those more responsible than others, and they will be held accountable, but again truth be told, if you're looking for the guilty, you need only look into a mirror. I know why you did it. I know you were afraid. Who wouldn't be? War, terror, disease. There were a myriad of problems which conspired to corrupt your reason and rob you of your common sense."

"God is in the rain."

But there are other great examples in art:

Jean Valjean in Les Mis

Scrooge

Tale of Two Cities

Darth Vader and his son.....
