Science fiction still is an idea genre.

I think... girls have a hard time being interesting. It’s actually easier to be famous, or notorious, than it is to be interesting. In our world, girls climb very well until they hit puberty-sexual maturity-and then they begin to fall out of the tree. They start role-playing instead of thinking, flirting instead of learning. They start admiring how smart the boys are-or how athletic or how handsome-instead of concentrating on their own intelligence.

Boys play with death as though it were a game, cutting their teeth on daggers.

Creation has the truth written all over it - the age of the universe, the history of the world - but nine-tenths of mankind either don't know it or think it's a sham, because it isn't what their book or their prophet says, and it isn't cozy or manipulable enough.

The sooner we can separate salvageable skeptics from self-righteous absolutists, the sooner we can move along.

There are writers who say they have no social responsibility except to write a good book, but that doesn't satisfy me.

Conflict acting on intelligence creates imagination. Faced with conflict, creatures are forced to imagine what will happen, where the next threat will come from. If there has never been conflict, imagination never develops. Wits arise in answer to danger, to pain, to tragedy. No one ever got smarter eating easy apples.
