Sun Tzu said: 4. Thus, what enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge. 5. Now this foreknowledge cannot be elicited from spirits; it cannot be obtained inductively from experience, nor by any deductive calculation. 6. Knowledge of the enemy’s dispositions can only be obtained from other men.
In business: 4. Thus, what enables the wise owner and the good leader to campaign and succeed, and achieve things beyond the reach of the mediocre people, is foreknowledge. 5. Now this foreknowledge cannot be elicited from spirits; it cannot be obtained from experience, nor by any calculations. 6. Knowledge of the competition can only be obtained from other people.
