《资治通鉴·周纪》45｜以史为鉴，君王到底该不该杀人成性？

Summary

This 芮淇讲透资治通鉴 episode opens the show’s 周纪三 range, from 320 to 298 BCE, and uses 孟子 / Mencius’s meeting with 魏襄王 to ask whether violent rulers can truly settle the realm. Mencius answers that only a ruler who does not love killing can unify, and the host reads that claim through Qin’s short-lived conquest, 项羽 versus 刘邦, the failed five-state assault on 函谷关, and 宋康王 / 宋君偃’s brutal rise and destruction. The episode’s core distinction is between taking power through force and keeping order through people-based legitimacy.

Key Claims

• 周纪三 covers twenty-three years from 320 to 298 BCE, spanning 周慎靓王’s six-year reign and the first seventeen years of 周赧王.
• In 320 BCE, Wei’s ruler lowers his title amid decline, and 齐威王 dies with 齐宣王 succeeding; this is compatible with the wiki’s existing correction that Qi Xuan Wang’s first regnal year belongs around 319 BCE.
• In 319 BCE, 秦国 attacks 韩国 and takes Yanling, while 魏惠王 / 梁惠王 dies and 魏襄王 succeeds.
• Mencius judges Wei Xiang Wang as lacking kingly presence, then answers his question about settling the realm by saying unity is necessary and that the unifying ruler will be one who does not love killing.
• The host treats 不爱杀人者能一之 as a durable-order claim rather than a naive denial that violent states can win short-term victories.
• Qin’s eventual conquest appears to challenge Mencius, but the host notes that the Qin dynasty was short-lived, while the later Chu-Han contrast makes 刘邦’s comparatively less-killing image the founder of a long Han order against 项羽.
• In 318 BCE, 楚国, 赵国, 魏国, 韩国, and 燕国 attack Qin with 楚怀王 as alliance leader, while Qi promises support but has 孟尝君 / 田文 make the Qi army move slowly.
• The five-state army reaches Hangu Pass but fails because each state wants to preserve strength and avoid attacking first; Qin cuts Chu’s grain route, Chu withdraws, and the rest follow.
• 宋康王 / 宋君偃 claims kingly title in 318 BCE after the earlier Song coup branch, expands against Qi, Chu, Wei, Xue, and Teng, and makes Song briefly strong while creating enemies on all sides.
• Song Kang Wang’s cruelty toward advisers and ordinary people destroys domestic support; Qi, Chu, and Wei attack, Song’s people scatter rather than defend him, he is killed, and 宋国 disappears.

Key Quotes

“不爱杀人者能一之” - Mencius’s answer to who can unify the realm.

Connections

• 孟子 / Mencius, 《孟子》, 魏襄王, 魏惠王 / 梁惠王, 孟子的民本合法性, 孟子仁政, and 不爱杀人者能一之 - Mencius dialogue and legitimacy branch.
• 周慎靓王, 周赧王, 周王室, 《资治通鉴》, and 战国时期 - 周纪三 chronology and annalistic frame.
• 秦国, 韩国, 魏国, 齐国, 齐威王, and 齐宣王 - 320-319 BCE state and succession notices.
• 合纵, 共同敌人联盟, 联盟自保失灵, 函谷关, 楚怀王, 孟尝君 / 田文, 楚国, 赵国, 燕国, and 秦国 - failed five-state anti-Qin coalition.
• 宋国, 宋剔成, 宋康王 / 宋君偃, 齐国, 楚国, 魏国, 薛地, and 民心型政治安全 - Song coup sequel, violent expansion, and destruction.
• 项羽, 刘邦, 西汉, 王道 versus 霸道, and 孟子理想主义的限度 - host’s later-history response to Mencius’s claim.

Contradictions

• No direct contradiction found. The episode’s 320 BCE Qi Wei Wang death / Qi Xuan Wang succession notice should be read with the existing 齐威王编年争议 correction: Qi Xuan Wang can succeed after Qi Wei Wang’s death while his first regnal year is still treated as 319 BCE.
• The source also does not fully overturn Mencius by noting Qin’s later conquest. It explicitly distinguishes violent acquisition from durable rule: Qin can conquer, but its short life and the later Liu Bang/Xiang Yu contrast are used to keep 不爱杀人者能一之 as a long-term legitimacy claim.
