Well its undoubtedly a pacifist chapter. However, I cannot understand this part:
"The wise man prefers the left. The man of war prefers the right" (Feng).
"When the gentleman is at home, he honors the left; When at war, he honors the right (Henricks).
"In ordinary life, a gentleman regards the left side as the place of honor: In war, the right side is the place of honor"(Wu).
I can't imagine it been a political ideological theme or is it.
