Robert A. Heinlein

By cultivating the beautiful we scatter the seeds of heavenly flowers, as by doing good we cultivate those that belong to humanity.

Heroism' often consists in keeping your head in an emergency and doing the best you can with what you have instead of panicking and being shot in the tail. People who fight this way win more battles than do intentional heroes; a glory hound often throws away the lives of his mates as well as his own.

There is no way that writers can be tamed and rendered civilized or even cured. The only solution known to science is to provide the patient with an isolation room, where he can endure the acute stages in private and where food can be poked in to him with a stick.

A community where everyone is a ruthless murderer, with handy access to death-dealing devices, is a very polite community.

Victory in defeat, there is none higher. She didn't give up, Ben; she's still trying to lift that stone after it has crushed her. She's a father working while cancer eats away his insides, to bring home one more pay check. She's a twelve-year-old trying to mother her brothers and sisters because mama had to go to Heaven. She's a switchboard operator sticking to her post while smoke chokes her and fire cuts off her escape. She's all the unsung heroes who couldn't make it but never quit.

Most people can't think, most of the remainder won't think, and the small fraction who do think mostly can't do it very well.

Remember this: once the human race is established on more than one planet and especially, in more than one solar system, there is no way now imaginable to kill off the human race.

Always cut the cards...and smile when you lose.

Sin is cruelty and injustice, all else is peccadillo. Oh, a sense of sin comes from violating the customs of your tribe. But breaking custom is not sin even when it feels so; sin is wronging another person.

Ability is a wonderful thing, but its value is greatly enhanced by dependability. Ability implies repeatability and accountability.

Do this. Don't do that. Stay back in line. Where's tax receipt? Fill out form. Let's see license. Submit six copies. Exit only. No left turn. No right turn. Queue up and pay fine. Take back and get stamped. Drop dead— but first get permit.

Neither individuals nor corporations have any right to come into court and ask that the clock of history be stopped, or turned back.

A great artist can look at an old woman, portray her exactly as she is ... and force the viewer to see the pretty girl she used to be ... more than that, he can make anyone with the sensitivity of an armadillo see that this lovely young girl is still alive

The supreme irony of life is that hardly anyone gets out of it alive.

There comes a time in the life of every human when he or she must decide to risk ‘his life, his fortune and his sacred honor’ on an outcome dubious. Those who fail the challenge are merely overgrown children, can never be anything else.

Dad claims that library science is the foundation of all sciences just as math is the key -- and we will survive or founder, depending on how well the librarians do their jobs. Librarians didn't look glamorous to me but maybe Dad had hit on a not very obvious truth.

Moving parts in rubbing contact require lubrication to avoid excessive wear. Honorifics and formal politeness provide lubrication where people rub together. Often the very young, the untravelled, the naive, the sophisticated deplore these formalities as 'empty,' 'meaningless,' or 'dishonest,' and scorn to use them. No matter how 'pure' their motives, they thereby throw sand into machinery that does not work too well at best.

The whole principle (censorship) is wrong; it's like demanding that grown men live on skim milk because the baby can't eat steak.

Goodness without wisdom always accomplishes evil.

Democracy is four wolves and a sheep voting on dinner.

Always tell her she is beautiful, especially if she is not.
