"But of the tree of the knowledge of good and evil, thou shalt not eat it; for in the day that thou eatest thereof thou shalt surely die.
- Genesis 2;17"
— Stephenie Meyer

"Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire,
I hold with those who favor fire.
But if I had to perish twice
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice."
— Robert Frost (Robert Frost's Poems)

"These violent delights have violent ends And in their triumph die, like fire and powder, Which, as they kiss, consume. (Romeo and Juliet, Act II, Scene VI )"
— William Shakespeare (Romeo and Juliet (Folger Shakespeare Library))

"Wisest is she who knows she does not know."
— Jostein Gaarder (Sophie's World: A Novel about the History of Philosophy)

"Shall I compare thee to a summer's day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date:
Sometimes too hot the eye of heaven shines,
And too often is his gold complexion dimm'd:
And every fair from fair sometimes declines,
By chance or natures changing course untrimm'd;
By thy eternal summer shall not fade,
Nor lose possession of that fair thou owest;
Nor shall Death brag thou wander'st in his shade,
When in eternal lines to time thou growest:
So long as men can breathe or eyes can see,
So long lives this and this gives life to thee."
— William Shakespeare
