“Certainty becomes you.”
“Certainty is not to be had. But as we learn this we become not more moral but more resigned. We become nihilists.”
“...while the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty.”
“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!”
“Power breeds certainty, and certainty has no clout against the unpredictable, whether you are playing poker or running a country.”
“All I know with utter certainty is this. Dan tamed me. We need each other.He has become unique to me in all the world.”
