It may be important to write a book that doesn't come up to what I would like to have rather than to write no book at all.

The only people who have the long view are some scientists and some science fiction writers.

I'm not sure a world run by women would be any better. They're human beings!

Science fiction still is an idea genre.

Do you realize it’s been only a century that we’ve been able to go from house to car to office to car to wherever, with the heater on, and the defroster on, protected from the rain and the cold? It hasn’t been much longer than that we’ve had lighting for streets. Think of all that darkness, all that world out there, all that mystery that we’ve turned into well-lighted concrete bunkers, safe and warm and dull.

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.

Mankind accepts good fortune as his due, but when bad occurs, he thinks it was aimed at him, done to him, a hex, a curse, a punishment by his deity for some transgression, as though his god were a petty storekeeper, counting up the day's receipts.
