“And always, he fought the temptation to choose a clear, safe course, warning 'That path leads ever down into stagnation.”

“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.”

With his gaze on the depths, he recognized a maelstrom of boiling rapids there, the mirror of his life-precipitous currents and plunges, all movement gathering up all substance. Leto’s words wound through his mind on a path of golden smoke: “Caution is the path to mediocrity.

“Most civilisation is based on cowardice. It's so easy to civilize by teaching cowardice. You water down the standards which would lead to bravery. You restrain the will. You regulate the appetites. You fence in the horizons. You make a law for every movement. You deny the existence of chaos. You teach even the children to breathe slowly. You tame.”

“Ready comprehension is often a knee-jerk response and the most dangerous form of understanding. It blinks an opaque screen over your ability to learn. Be warned. Understand nothing. All comprehension is temporary.”
