War is a profession by which a man cannot live honorably; an employment by which the soldier, if he would reap any profit, is obliged to be false, rapacious, and cruel.

If someone puts up the argument that King Louis gave the Romagna to Pope Alexander, and the kingdom of Naples to Spain, in order to avoid a war, I would answer as I did before: that you should never let things get out of hand in order to avoid war.

Discipline in war counts more than fury.
