A man wants his virility regarded. A woman wants her femininity appreciated, however indirect and subtle the indications of regard and appreciation. [Here] one is respected and judged only as a human being. It is an appalling experience.
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 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.
