Victor Hugo 

"We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion. And medicine, law, business, engineering, these are noble pursuits and necessary to sustain life. But poetry, beauty, romance, love, these are what we stay alive for. To quote from Whitman, 'O me! O life!... of the questions of these recurring; of the endless trains of the faithless... of cities filled with the foolish; what good amid these, O me, O life?' Answer. That you are here - that life exists, and identity; that the powerful play goes on and you may contribute a verse. That the powerful play goes on and you may contribute a verse. What will your verse be?" 

~ Robin Williams in "Dead Poets Society" (1989).

"This is the point.
The duke is very strangely gone from hence;
Bore many gentlemen, myself being one,
In hand and hope of action: but we do learn
By those that know the very nerves of state,
His givings-out were of an infinite distance
From his true-meant design. Upon his place,
And with full line of his authority,
Governs Lord Angelo; a man whose blood
Is very snow-broth; one who never feels
The wanton stings and motions of the sense,
But doth rebate and blunt his natural edge
With profits of the mind, study and fast.
He--to give fear to use and liberty,
Which have for long run by the hideous law,
As mice by lions--hath pick'd out an act,
Under whose heavy sense your brother's life
Falls into forfeit: he arrests him on it;
And follows close the rigour of the statute,
To make him an example. All hope is gone,
Unless you have the grace by your fair prayer
To soften Angelo: and that's my pith of business
'Twixt you and your poor brother."

--Lucio from "Measure for Measure" (1.4) by William Shakespeare

One of George Eliot's best-loved works, The Mill on the Floss is a brilliant portrait of the bonds of provincial life as seen through the eyes of the free-spirited Maggie Tulliver, who is torn between a code of moral responsibility and her hunger for self-fulfillment. Rebellious by nature, she causes friction both among the townspeople of St. Ogg's and in her own family, particularly with her brother, Tom. Maggie's passionate nature makes her a beloved heroine, but it is also her undoing.
The Mill on the Floss is a luminous exploration of human relationships and of a heroine who critics say closely resembles Eliot herself.

"I am a ridiculous person. Now they call me a madman. That would be a promotion if it were not that I remain as ridiculous in their eyes as before. But now I do not resent it, they are all dear to me now, even when they laugh at me — and, indeed, it is just then that they are particularly dear to me. I could join in their laughter — not exactly at myself, but through affection for them, if I did not feel so sad as I look at them. Sad because they do not know the truth and I do know it. Oh, how hard it is to be the only one who knows the truth! But they won't understand that. No, they won't understand it."

--from "The Dream of a Ridiculous Man" (1877) by Fyodor Dostoevsky 

"The sun was almost down on the mountain tops, and the shadows of the whole group fell upon the snow. I saw the Count lying within the box upon the earth, some of which the rude falling from the cart had scattered over him. He was deathly pale, just like a waxen image, and the red eyes glared with the horrible vindictive look which I knew so well. As I looked, the eyes saw the sinking sun, and the look of hate in them turned to triumph. But, on the instant, came the sweep and flash of Jonathan's great knife. I shrieked as I saw it shear through the throat. Whilst at the same moment Mr. Morris's bowie knife plunged into the heart. It was like a miracle, but before our very eyes, and almost in the drawing of a breath, the whole body crumbled into dust and passed from our sight. I shall be glad as long as I live that even in that moment of final dissolution, there was in the face a look of peace, such as I never could have imagined might have rested there."

--Mina Harker from "DRACULA" by Bram Stoker
