Frank Herbert

Secrets give birth to more secrets.

Sand keeps the skin clean, and the mind.

Peering back through the magnifying glass of time, men and women in the future view the personalities of the Great Revolt as larger-than-life. Such an impression comes not through any distortion of the glass, nor from a process of embellishment that generates mythology. Instead, the heroes of the Jihad were much as they are now remembered; they rose to the occasion when humanity needed them more then ever before.

Here is where the analytical power of the thinking machines fails them: they believe they have no weaknesses.

Those who refuse to fight against thinking machines are traitors to the human race. Those who do not use every possible weapon are fools.

Endurance. Belief. Patience. Hope. These are the key words of our existence.

Everything in the universe contains flaws, ourselves included. Even God does not attempt perfection in His creations. Only humankind has such foolish arrogance.

A human lifespan is not always sufficient for a person to achieve greatness. To counter this, some of us have seized more time for ourselves.

There is no such thing as the future. Humankind faces multiple possible futures, many of which hinge on seemingly inconsequential events.

In truth, is it better to remember or to forget? We must balance this decision between our history and our humanity.

Thoughts become weapons. Philosophies are distinct reasons for war. Good intentions are the most destructive arsenal of all.

The weakness of thinking machines is that they actually believe all the information they receive, and react accordingly.
