“How to Tell a True War Story” from Tim O’Brien’s The Things They Carried:
“it can be argued, for in stance, that war is grotesque. But in truth war is also beauty.”

I understand O’Brien said that war is ugly, this is a common sense for all the people (who had not been in the war); however, for the soldiers who witness the war, they understand the beauty, like O’Brien use beautiful words to describe the death of Lemon. For them, this is the truth.
