The quality of decision is like the well-timed swoop of a falcon which enables it to strike and destroy its victim.
All war is deception.
O divine art of subtlety and secrecy!
To capture an enemies army is better than to destroy it.
Be subtle! be subtle! and use your spies for every kind of business.
Prohibit the taking of omens, and do away with superstitious doubts. Then, until death itself comes, no calamity need be feared.
