Capitalism’s grow-or-die imperative stands radically at odds with ecology’s imperative of interdependence and limit. The two imperatives can no longer coexist with each other; nor can any society founded on the myth that they can be reconciled hope to survive. Either we will establish an ecological society or society will go under for everyone, irrespective of his or her status.

Even 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.

When you light a candle, you also cast a shadow.

Science fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative. If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.

You 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?

Who knows a man's name, holds that man's life in his keeping. Thus to Ged, who had lost faith in himself, Vetch had given him that gift that only a friend can give, the proof of unshaken, unshakeable trust.
