Science Fiction has always been and will always be a fable teacher of morality.

You don't organize metaphors . . . you explode them.

We are all . . . children of this universe. Not just Earth, or Mars, or this system, but the whole grand fireworks. And if we are interested in Mars at all, it is only because we wonder over our past and worry terribly about our possible future.

The human race likes to give itself airs. One good volcano can produce more greenhouse gases in a year than the human race has in its entire history.

Every time you take a step, even when you don't want to. . . . When it hurts, when it means you rub chins with death, or even if it means dying, that's good. Anything that moves ahead, wins. No chess game was ever won by the player who sat for a lifetime thinking over his next move.

You're not like the others. I've seen a few; I know. When I talk, you look at me. When I said something about the moon, you looked at the moon.

Stuff your eyes with wonder.
