dune quotes

To attempt an understanding of Muad'Dib without understanding his mortal
enemies, the Harkonnens, is to attempt seeing Truth without knowing Falsehood.
It is the attempt to see the Light without knowing Darkness. It cannot be.

-from "Manual of Muad'Dib" by the Princess Irulan

Prophecy and prescience--How can they be put to the test in the face of the
unanswered questions? Consider: How much is actual prediction of the "waveform"
(as Muad'Dib referred to his vision-image) and how much is the prophet shaping
the future to fit the prophecy? What of the harmonics inherent in the act of
prophecy? Does the prophet see the future or does he see a line of weakness, a
fault or cleavage that he may shatter with words or decisions as a
diamond-cutter shatters his gem with a blow of a knife?

"Yueh! Yueh! Yueh!" goes the refrain. "A million deaths were not enough for
Yueh!"
