“I know the evil of my ancestors because I am those people. The balance is delicate in the extreme. I know that few of you who read my words have ever thought about your ancestors this way. It has not occurred to you that your ancestors were survivors and that the survival itself sometimes involved savage decisions, a kind of wanton brutality which civilized humankind works very hard to suppress. What price will you pay for that suppression? Will you accept your own extinction?
-The Stolen Journals”
― Frank Herbert, God Emperor of Dune

“Abandon certainty! That's life's deepest command. That's what life's all about. We're a probe into the unknown, into the uncertain. Why can't you hear Muad'Dib? If certainty is knowing absolutely an absolute future, then that's only death disguised! Such a future becomes now!”
― Frank Herbert, Children of Dune

“Empires do not suffer emptiness of purpose at the time of their creation. It is when they have become established that aims are lost and replaced by vague ritual.

-Words of Muad'dib by Princess Irulan.”
― Frank Herbert, Dune Messiah

“Dangers lurk in all systems. Systems incorporate the unexamined beliefs of their creators. Adopt a system, accept its beliefs, and you help strengthen the resistance to change”
― Frank Herbert, God Emperor of Dune
