“The limit of the law is the limit of enforcement—the real limit of organized society.”

“Growth is limited by that necessity which is present in the least amount.”

“Constitutions become the ultimate tyranny," Paul said. "They’re organized power on such a scale as to be overwhelming. The constitution is social power mobilized and it has no conscience.

“Maud’Dib could indeed, see the Future, but you must understand the limits of this power. Think of sight. You have eyes, yet cannot see without light. If you are on the floor of a valley, you cannot see beyond the valley. Just so, Maud’Dib could not always choose to look across the mysterious terrain. He tells us that a single obscure decision of prophecy, perhaps the choice of one word over another, could change the entire aspect of the future. He tells us “The vision of time is broad, but when you pass through it, time becomes a narrow door.” And always, he fought the temptation to choose a clear, safe course, warning “That path leads ever down into stagnation.”
