To endure oneself may be the hardest task in the universe. You cannot hire a wise man or any other intellect to solve it for you. There's no writ of inquest or calling of witness to provide answers.

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.

Many have marked the speed with which Muad'Dib learned the necessities of Arrakis. The Bene Gesserit, of course, know the basis of this speed. For the others, we can say that Muad'Dib learned rapidly because his first training was in how to learn. And the first lesson of all was the basic trust that he could learn.

If you must label the absolute, use its proper name: Temporary.
