We repeat again: strength of character does not consist solely in having powerful feelings, but in maintaining one’s balance in spite of them. Even with the violence of emotion, judgment and principle must still function like a ship’s compass, which records the slightest variations however rough the sea.

War is the domain of physical exertion and suffering.

There are times when the utmost daring is the height of wisdom.

Principles and rules are intended to provide a thinking man with a frame of reference.

Pursue one great decisive aim with force and determination. The bloody solution of the crisis, the effort for the destruction of the enemy's forces, is the first-born son of war. Only great and general battles can produce great results. Blood is the price of victory.

War is nothing but a duel on a larger scale.

War is the realm of uncertainty; three quarters of the factors on which action is based are wrapped in a fog of greater or lesser uncertainty.
