The Art of War by Sun Tzu was written in China in the late-sixth century BC and is one of the oldest and most successful books on military strategy in the world. The book is attributed to Sun Tzu, a high ranking military general and strategist of the Kingdom of Wu. This translation of The Art of War, by Lionel Giles, is written in simple form without notes so that the reader may interpret and form their own opinions as to meaning.
The Art of War is of equal value to both military historians and students of business strategy.
Sun Tzu said: The art of war is of vital importance to the State.
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.
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.
(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.
Heaven signifies night and day, cold and heat, times and seasons.
Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death.
The Commander stands for the virtues of wisdom, sincerity, benevolence, courage and strictness.
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.
These five heads should be familiar to every general: he who knows them will be victorious; he who knows them not will fail.
Therefore, in your deliberations, when seeking to determine the military conditions, let them be made the basis of a comparison, in this wise:
(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?
By means of these seven considerations I can forecast victory or defeat.
The general that hearkens to my counsel and acts upon it, will conquer: let such a one be retained in command! The general that hearkens not to my counsel nor acts upon it, will suffer defeat: let such a one be dismissed!
