In The End Quotes (page 26)
of all the weapons of destruction that man could invent, the most terrible-and the most powerful-was the word. Daggers and spears left traces of blood; arrows could be seen at a distance. Poisons were detected in the end and avoided. But the word managed to destroy without leaving clues.
Paulo Coelho
When people discuss his plays, he says that he feels like he's standing at customs watching an official ransack his luggage. He cheerfully declares responsibility for a play about two people, and suddenly the officer is finding all manner of exotic contraband like the nature of God and identity, and while he can't deny that they're there, he can't for the life of him remember putting them there. In the end, a play is not the product of an idea; an idea is the product of a play.
Tom Stoppard
It is those who have compassion for all life who will best safeguard the life of man. Those who become aroused only when man is endangered become aroused too late. We cannot make the world uninhabitable for other forms of life and have it habitable for ourselves. It is the conservationist who is concerned with the welfare of all the land and life of the country, who, in the end, will do most to maintain the world as a fit place for human existence.
