The Art of War
Sun Tzu
I. Laying Plans
1. Sun Tzu said: The art of war is of vital importance to the State.
2. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of
inquiry which can on no account be neglected.
3. 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.
4. These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Commander; (5) Method
and discipline.
5,6. 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.
7. Heaven signifies night and day, cold and heat, times and seasons.
8. Earth comprises distances, great and small; danger and security; open ground and
narrow passes; the chances of life and death.
9. The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and
strictness.
10. By method and discipline are to be understood the marshaling of the army in its proper
subdivisions, the graduations of rank among the officers, the maintenance of roads by
which supplies may reach the army, and the control of military expenditure.
11. These five heads should be familiar to every general: he who knows them will be
victorious; he who knows them not will fail.
12. Therefore, in your deliberations, when seeking to determine the military conditions, let
them be made the basis of a comparison, in this wise:--
13. (1) Which of the two sovereigns is imbued with the Moral law? (2) Which of the two
generals has most ability? (3) With whom lie the advantages derived from Heaven and
Earth? (4) On which side is discipline most rigorously enforced? (5) Which army is
stronger? (6) On which side are officers and men more highly trained? (7) In which army is
there the greater constancy both in reward and punishment?
