“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.”

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

“The vision of time is broad, but when you pass through it, time becomes a narrow door.”

“Think you of the fact that a deaf person cannot hear. Then, what deafness may we not all possess? What senses do we lack that we cannot see and cannot hear another world all around us?”

“We say, "Well, the only answer is...." or, "If you would just. . . ." Whatever follows these two statements narrows the choices right there. It gets the vision right down close to the ground so that you don't see anything happening outside. Humans tend not to see over a long range. Now we are required, in these generations, to have a longer range view of what we inflict on the world around us. This is where, I think, science fiction is helping. I don't think that the mere writing of such a book as Brave New World or 1984 prevents those things which are portrayed in those books from happening. But I do think they alert us to that possibility and make that possibility less likely. They make us aware that we may be going in that direction.”

“There was a man who sat each day looking out through a narrow vertical opening where a single board had been removed from a tall wooden fence. Each day a wild ass of the desert passed outside the fence and across the narrow opening—first the nose, then the head, the forelegs, the long brown back, the hindlegs, and lastly the tail. One day, the man leaped to his feet with the light of discovery in his eyes and he shouted for all who could hear him: “It is obvious! The nose causes the tail!”

“Things could not be forever ordered and formulated. He had to find the rhythm of change and see between the changes to the changing itself.”
