Prohibit the taking of omens, and do away with superstitious doubts. Then, until death itself comes, no calamity need be feared.
Foreknowledge cannot be gotten from ghosts and spirits, cannot be had by analogy, cannot be found out by calculation. It must be obtained from people, people who know the conditions of the enemy.
But a kingdom that has once been destroyed can never come again into being; nor can the dead ever be brought back to life.
