All the same, the fundamental truths which govern that art are still unchangeable; just as the principles of mechanics must always govern architecture, whether the building be made of wood, stone, iron or concrete; just as the principles of harmony govern music of whatever kind. It is still necessary, then, to establish the principles of war.

A beaten general is disgraced forever.

In whatever position you find yourself, determine first your objective.

The most powerful weapon on earth is the human soul on fire.

A battle won is a battle which we will not acknowledge to be lost.

Aviation is fine as a sport. But as an instrument of war, it is worthless.

The unknown is the governing principle of war.
