“If there were no heaven and no hell, I would still want to be a Christian because of what it does for our homes and our own families in this life.”

“A moderately bad man knows he is not very good: a thoroughly bad man thinks he is alright. This is common sense really. You understand sleep when you are awake, not well you are sleeping.”

“All you have is today. Never mourn for tomorrow that is past and gone. You don’t deserve to starve today of its pleasure and treasure. Feel happy!”

“All knowledge leads to self-knowledge.”

“Your real, new self (which is Christ's and also yours, and yours just because it is His) will not come as long as you are looking for it. It will come when you are looking for Him. Does that sound strange? The same principle holds, you know, for more everyday matters. Even in social life, you will never make a good impression on other people until you stop thinking about what sort of impression you are making. Even in literature and art, no man who bothers about originality will ever be original whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it. The principle runs through all life from top to bottom, Give up yourself, and you will find your real self. Lose your life and you will save it. Submit to death, death of your ambitions and favourite wishes every day and death of your whole body in the end submit with every fibre of your being, and you will find eternal life. Keep back nothing. Nothing that you have not given away will be really yours. Nothing in you that has not died will ever be raised from the dead. Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him, and with Him everything else thrown in.”

“I am certainly not an advocate for frequent and untried changes in laws and constitutions. I think moderate imperfections had better be borne with; because, when once known, we accommodate ourselves to them, and find practical means of correcting their ill effects. But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors.”

“Surely what a man does when he is taken off his guard is the best evidence for what sort of man he is.”

“If a man aspires to a righteous life, his first act of abstinence if from injury to animals.”

“A mind ill with negative attitudes is more dangerous than a sick body, for its sickness is always contagious”

“Helen Keller, author, speaker, and advocate for disabled persons, asserted,"Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing.” 

“God wants you to trust Him and have a happy expectation for something good. If you’re in a tough situation today, expect it to change. If you’re in a good situation today, expect it to get even better. God is a God of hope.”

“You must be always hungry and thirsty.” The Baron caressed his bulges beneath the suspensors. “Like me.”

“Your co-orbital anti-satellite weapon is designed to destroy satellites. Furthermore, the Soviet Union began research in defenses utilizing directed energy before the United States did and seems well along in research (and incidentally, some testing outside laboratories) of lasers and other forms of directed energy. I do not point this out in reproach or suggest these activities are in violation of agreements, but if we were to follow your logic to the effect that what you call space-strike weapons would only be developed by a country planning a first strike, what would we think?”

“The whole idea of motivation is a trap. Forget motivation. Just do it.”

“I will tell you a thing about your new name,” Stilgar said. “The choice pleases us. Muad’Dib is wise in the ways of the desert. Muad’Dib creates his own water. Muad’Dib hides from the sun and travels in the cool night. Muad’Dib is fruitful and multiplies over the land. Muad’Dib we call ‘instructor-of-boys.’ That is a powerful base on which to build your life, Paul-Muad’Dib, who is Usul among us. We welcome you.” Stilgar”
