The Art of War, then, is governed by five constant factors, to be taken into account in one's deliberations, when seeking to determine the conditions obtaining in the field.
These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Commander; (5) Method and discipline.
The MORAL LAW causes the people to be in complete accord with their ruler, so that they will follow him regardless of their lives, undismayed by any danger.
METHOD AND DISCIPLINE are paramount in the marshaling of forces, effective communications throughout the chain of command, logistics, and the expenditure of military funds.
Therefore, in your deliberations, when seeking to determine the proper strategic outcome, let your decision be guided through the basis of a comparison, by answering the proper questions.
While heeding the benefit of my counsel, avail yourself also of any helpful circumstances over and beyond the ordinary rules. According as circumstances are favorable, one should modify one's plans.
If your enemies have advantage, bait them; if confused, capture them; if they are numerous, prepare for them; if strong, avoid them; if angry, disturb them; if they are humble, make them haughty; if they are relaxed, toil them; if they are united, separate them.
Before doing battle, one calculates in the temple and will win, because many calculations were made; before doing battle, one calculates in the temple but will lose, because few calculations were made.
Many calculations mean victory; few calculations mean no victory; then how much worse when there are no calculations? From this perspective I can clearly predict victory or defeat.
