“I'll not always be here on guard. The stars twinkle in the Milky Way and the wind sighs for songs across the empty fields of a planet a Galaxy away. You won't always be here. But before you go, whisper this to your sons and their sons - "The work was free. Keep it so.”

“Freedom is for honest people. No man who is not himself honest can be free – he is his own trap.”

“One's attitude toward life makes every possible difference in one's living. You know, you don't have to study a thousand ancient books to discover that fact. But sometimes it needs to be pointed out again that life doesn't change so much as you. ...The day when you stop building your own environment, when you stop building your own surroundings, when you stop waving a magic hand and gracing everything around you with magic and beauty, things cease to be magical, things cease to be beautiful. Well, maybe you've just neglected somewhere back in the last few years to wave that magic hand.”

“Scientology does not teach you. It only reminds you. For the information was yours in the first place.”

“When reading a book, be very certain that you never go past a word you do not fully understand. The only reason a person gives up a study or becomes confused or unable to learn is because he or she has gone past a word that was not understood.”

“You don't get rich writing science fiction. If you want to get rich, you start a religion.”

“The wise man tests before he talks. The critic but follows the fad of a cynical and apathetic age.”
