Use Strengths Over Faults / 用人取长弃短

Use strengths over faults / 用人取长弃短 is a recurring talent-selection lesson in the Ruiqi pre-Qin branch. 《资治通鉴·周纪》06丨魏文侯选谁当宰相呢（1） adds an early version through 李克 evaluating 吴起 for 魏文侯: Wu Qi’s reputation and desires are dangerous, but his military ability is presented as role-critical for 魏国.

Zhouji 09 adds a cleaner later version through 子思 recommending 苟变. The ruler knows Gou Bian can command troops but hesitates because Gou Bian once took two eggs while collecting taxes.

Zisi’s analogy is practical: a carpenter uses usable timber by taking the strong part and discarding the weak part. In a wartime state, losing a capable commander over a small blemish can harm the polity more than the original fault did.

The concept does not say misconduct never matters. Its source-scoped claim is narrower: rulers need proportion, role-fit, and context when judging flawed talent, especially when state survival depends on scarce military ability.

《资治通鉴·周纪》75-2丨“穷奢极侈”的祖师爷管仲 adds a sharper political version through 管仲. Guan Zhong is not merely flawed; he is a former enemy who tried to stop 姜小白 from taking power. 鲍叔牙’s recommendation asks the ruler to judge whether the talent’s state-building value outweighs the personal and factional injury.

Hanji 154 adds the Chen Ping accusation version. 魏无知 and 陈平 do not ask 刘邦 to ignore every concern; Chen Ping explains the concrete “受金” charge and offers to return the money if his plans lack value. Liu Bang’s decision to keep and reward him makes the concept operate through proof of usefulness rather than through a claim that faults never matter.

Hanji 157 part 2 adds a defeated-adviser version through 韩信 and 李左车. Li Zuoche’s defeat could disqualify him socially, but Han Xin treats his earlier correct advice as evidence of usable strategic judgment. The source therefore turns “defeated general” status into a context marker rather than a total verdict on ability.

Key Claims

  • Talent evaluation should separate role-critical strengths from lesser defects.

  • Small past faults can become strategically expensive if they cause leaders to waste scarce capability.

  • Severe defects still need role-bound judgment; the Wu Qi case keeps the danger visible while arguing for military use.

  • The lesson is bounded by context: wartime urgency changes the tradeoff but does not erase judgment.

  • The Guan Zhong case adds a ruler-level version: using a former enemy can be rational when the office requires scarce statecraft talent.

  • The episode treats Zisi’s argument as “资治” material because it links moral evaluation to governing consequences.

  • Hanji 154 adds that preserving useful talent may require separating a concrete, explainable fault from an ungrounded smear.

  • Hanji 157 part 2 adds that defeat does not necessarily invalidate counsel; a commander can separate a person’s current defeated status from the quality of his earlier judgment.
