Violence harms the one who does it as much as the one who receives it. You could cut down a tree with an axe. The axe does violence to the tree, and escapes unharmed. Is that how you see it? Wood is soft compared to steel, but the sharp steel is dulled as it chops, and the sap of the tree will rust and pit it. The mighty axe does violence to the helpless tree, and is harmed by it. So it is with men, though the harm is in the spirit.
Robert JordanIf you ask the lion to protect from from wolves, you have only chosen to end in one belly instead of another.
Robert JordanYes...how else could Demandred explain the skill of the enemy general? Only a man with the experience of an ancient was so masterly at the dance of battlefields. At their core, many battle tactics were simple. Avoid being flanked, meet heavy force with pikes, infantry with a well-trained line, channelers with other channelers. And yet, the finesse of it...the little details...these took centuries to master. No man from this Age had lived long enough to learn the details with such care.
