" Governments may rise and fall for reasons which appear insignificant, Prince. What small events! An argument between two women . . . which way the wind blows on a certain day . . . a sneeze, a cough, the length of a garment or the chance collision of a fleck of sand and a courtier’s eye. It is not always the majestic concerns of Imperial ministers which dictate the course of history, nor is it necessarily the pontifications of priests which move the hands of God. "

― Frank Herbert , Children of Dune (Dune, #3)
