All knowledge is local, all truth is partial. No truth can make another truth untrue. All knowledge is part of the whole knowledge. Once you have seen the larger pattern, you cannot go back to seeing the part as the whole.
Ursula K. Le GuinEven in the obscure vast history of a planet the time it takes to make a forest counts. It takes a while. And not every planet can do it; it is no common effect, that tangling of the sun's first cool light in the shadow and complexity of innumberable wind-stirred branches.
Ursula K. Le GuinA forest ecology is a delicate one. If the forest perishes, its fauna may go with it. The Athshean word for world is also the word for forest.
Ursula K. Le GuinYou will die. You will not live forever. Nor will any man nor any thing. Nothing is immortal. But only to us is it given to know that we must die. And that is a great gift: the gift of selfhood. For we have only what we know we must lose, what we are willing to lose... That selfhood which is our torment, and our treasure, and our humanity, does not endure. It changes; it is gone, a wave on the sea. Would you have the sea grow still and the tides cease, to save one wave, to save yourself?
Ursula K. Le Guin
