Like the sun and moon, they end but to begin anew; like the four seasons, they pass away to return once more.

All war is based on deception.

It is only one who is thoroughly acquainted with the evils of war that can thoroughly understand the profitable way of carrying it on.

In war, then, let your great object be victory, not lengthy campaigns.

A clever general... avoids an army when its spirit is keen, but attacks it when it is sluggish and inclined to return. This is the art of studying moods. Disciplined and calm, he awaits the appearance of disorder and hubbub among the enemy. This is the art of retaining self-possession.

Those skilled at making the enemy move do so by creating a situation to which he must conform; they entice him with something he is certain to take, and with lures of ostensible profit they await him in strength.

Invincibility lies in the defense; the possibility of victory in the attack.

Ponder and deliberate before you make your move. He will conquer who has learned the artifice of deviation. Such is the art of maneuvering.

What is of the greatest importance in war is extraordinary speed: One cannot afford to neglect opportunity.
