Mencius 7B.4: skill in war is a great crime
Mencius argues that turning the arts of battle into admirable expertise already reveals a deeply disordered hierarchy of values.
孟子曰:「有人曰:『我善為陳,我善為戰』,大罪也。國君好仁,天下無敵焉,南面而征北狄怨,東面而征西夷怨,曰:『奚為後我?』武王之伐殷也,革車三百兩,虎賁三千人。王曰:『無畏!寧爾也,非敵百姓也。』若崩厥角稽首。征之為言正也,各欲正己也,焉用戰?」
Mencius said, 'There are men who say "I am skilful at marshalling troops, I am skilful at conducting a battle!" They are great criminals. If the ruler of a State love benevolence, he will have no enemy in the kingdom. When Tang was executing his work of correction in the south, the rude tribes on the north murmured. When he was executing it in the east, the rude tribes on the west murmured. Their cry was "Why does he make us last?" When king Wu punished Yin, he had only three hundred chariots of war, and three thousand life-guards. The king said, "Do not fear. Let me give you repose. I am no enemy to the people!" On this, they bowed their heads to the earth, like the horns of animals falling off. "Royal correction" is but another word for rectifying. Each State wishing itself to be corrected, what need is there for fighting?'

Central question
Why does Mencius say that boasting of skill in formations and war is itself a great crime?

Because it shows that a person has made the capacity to seize and subdue into a central object of admiration. Mencius is correcting the hierarchy: when a ruler truly loves benevolence, the key to allegiance is not superior killing power but superior self-rectification and care for the people.
First principle
What is most dangerous is not violence alone, but the elevation of violent technique into an ideal of excellence.
Why it matters

Do not read it as denying every form of defense. Mencius is attacking the move that makes military prowess the primary language of political legitimacy and its practitioners the highest human type.
